Question about the Y2P Dual Core processor

Ok, so I was an an idiot and always thought that i7 meant quad core and was better than i5. However I just realized that there are some laptops with i5 that are quad core. On the other hand, this i7 Y2P laptop (which I won't get to play with till the 21st, since I am out of the country) has a dual core.
I now have a lenovo z570 quad-core i7 (note to Lenovo: still upset Lenovo about our power management software that never got fixed after 2 years). How much of a speed decrease am I expected to see???
I am going from quad core to dual core, 16 gb ram to 8 gb, 1 TB HDD (256 SSD + 750 HDD) to only 256 SSD.... Feels like I am compromising a lot for a touch screen.
Should I return the laptop?
Legit this whole i7 and i5 is crap marketing to get more $ imo. At the end of the day, I prefer quad-core i5 over dual core i7. What is the difference?
Looking at it, I see only a 0.4 GHz between the i5 and i7 model, both being dual core with hyperthreading. In the end, i7 is like $300 more. Why?
Feel like I overspent on this laptop cuz of a marketing gimmick.

Reading a bit more about it, I don't think there's any architecture difference, and the suggestion that these are actually the same part just programmed / binned / labeled differently sounds reasonable as Intel will not want to run two different manufacturing processes if they can get away with one.
The i7 is clocked a bit faster and has an extra MB of cache memory (those with manufacturing defects in cache might become i5s with that MB of cache disabled).
The i7 is definitely faster, but otherwise does not offer any other feature advantages that I can see, and the full-speed difference seems to be on the order of 15%, which is unlikely to make a difference in what you can use the machine for.
In gaming you might go from 30fps to 32fps say. It's probably not enough to run at a higher resolution or a higher quality setting.
Also, both processors try to run with lower clock speeds for both processor and graphics as much of the time as they can get away with, so I think most every-day activity will see nearly identical performance between the two.
Getting the 256GB SSD and 8GB of RAM is definitely worth it, so if it's then only another $100 for the i7 then maybe, but I'm really happy now that I went for the i5 since it doesn't seem like I'm missing out on anything. My i5 Y2P turns out to be a very good gaming ssytem and I have not had any performance issues with it.

Question about the new i5/i7 processors

I have been wondering if anybody had a definitive answer as to whether the new i5 and i7 processors are the desktop chips or their mobile counterparts? I know previous gen imacs use mobile parts but I've heard conflicting reports about the new 27 inch imacs. Some people say they are using desktop parts now while others claim they are still mobile processors...does anybody here know? I can't seem to find the information because I'm not really a techie so I don't really understand intels system for identifying their processors. The reason I ask is I recently placed an order for the i5 imac, I was comparing some i5/i7 benchmarking tests and ultimately decided the i5 was more than up to the job...however, now I don't even know if I was comparing the right chips (I didn't know there were different versions of the i5 and i7). Also, I had some concern with the heat issue, from what I've read the i7 produces tremendous heat so I also factored that in to my decision. I know Apple makes quality stuff (I love my MBP) and they placed the GPU and CPU on opposite ends of the imac, AND it has 3 fans AND the back is basically a HUGE heatsink lol...but I still wonder if the heat will cause the i7 to have a shorter expected life than the i5?(which is also pretty hot I guess). I thought I had my mind made up but this is turning out to be a very confusing process for me. If heat will effect the life cycle with only a relatively small power boost I'll stick with the i5...but if the versions of the chips they are using are mobile or not going to have this problem than I don't know what to do lol. Also, could you replace the i5 with an i7 later on down the road? AHHHH....can somebody help I'm spending so much money here I don't want to make a mistake :/

thanks for the help everyone. After reviewing all the information I think I'm gonna go with the i7...it will be $180 for me because of a student discount so in the end I guess thats not too much to pay for the increased speed and hyper-threading (which I probably will see no benefit from now but down the road...who knows). I had to cancel my order for the i5 anyway because after going into the Apple store last night to fondle the 27 inch imacs (which I hadn't seen in person yet) I realized I did not like the new keyboard ( don't get me wrong its a nice product but I use the Adobe CS4 software for digital art and animation so so lacking a numerical keypad for keystroke shortcuts is a little impractical for me).
Since I had to cancel and reorder anyway I'm now thinking I may as well upgrade to the i7 and be done with the doubting my decision lol. I haven't pulled the trigger yet but I will probably order today. Apparently the i5 and i7 have the same wattage so I guess if one will overheat the other will too so that kills that debate in my my mind.
BTW if anybody has not yet seen the 27 inch imacs in person yet they are behemoths...beautiful behemoths. I can't wait to have that much canvas space to paint in Photoshop.
Thanks again everyone.

Labview 7.1 and Dual Core Processors

Hi,
I was wondering if anyone has encountered any problems using Labview
7.1 and the newer dual-core processors. I have a Dell Dimension DXPO51,
2.8 GHz Pentium D with 1 GB ram. There is NO virus software or any
other non-essential programs running in the background. The computer is
totally dedicated to controlling a machine.
Other NI boards installed: PCI-6221 for analog inputs, PCI-6602 for
reading encoders, PCI-7352 Motion Control board to control 2 motors.
The problem:
Periodically when I start my program, it locks up and I get the "Tell
Microsoft about this problem..." screen. After it exits out of Labview
and I restart, the Run arrow is not broken but the program will not run
until I make a change on the block diagram. Then I can run again.
Doesn't happen all the time, doesn't happen after running after a
certain amount of time, doesn't happen after a particular change is
made (i.e. adding case statements, adding an event, etc.). In other
words, totally random.
I have tried totally uninstalling ALL National Instruments software,
including cleaning the registry, and re-installing everything. Didn't
help.
The machine will be shipping with the executable file only but I'm still leary of problems arising due to this issue.
Any help or suggestions of things to try would be appreciated.
Thanks,
Teri

Hi Teri,
I've seen scattered reports of users having trouble with dual-processor
machines with earlier versions of LabVIEW, though I'm not aware of
verified solutions in those cases. The dual-processor operation
should be completely transparent to LabVIEW, although I know XP has had
some difficulties in providing the abstraction correctly. A
workaround that has been successful in the past is to set the processor
affinity for LabVIEW to a single processor. This should eliminate
the dual-processor nature of the system from consideration. If
the problem still recurs after that, then the issue stems from another
source and we can investigate further. Does it show this behavior
with any program (or just by opening the LabVIEW environment)?
How often does this occur (10%, 50% of the time)?
Cheers,

Using the 2nd of a dual core processor

I have a dual core processor laptop and currently it isn't using the 2nd one at the moment. The first one is full and I am getting messages saying I have no memory space. How can I use the 2nd processor?

We need to know your full model number, like Satellite A215-S7437, and your Part Number, like PSAFGU-00L002. You can find this information on the Toshiba label on the bottom of your computer. Also, we need your operating system version, like Windows 7 32bit.
In addition, give us the exact error message that you are getting. Do not paraphrase, spelling and syntax are important. A screen shot of the error message would be best.
However, I would mention that your processor(s), your available system RAM (Random Access Memory), and the available space on your HDD (Hard Disk Drive), are three completely different things.

A question about the impact of SQL*PLUS SERVEROUTPUT option on v$sql

Hello everybody,
SQL> SELECT * FROM v$version;
BANNER
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE    11.2.0.1.0 Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
SQL>
OS : Fedora Core 17 (X86_64) Kernel 3.6.6-1.fc17.x86_64I would like to ask a question about the SQL*Plus SET SERVEROUTPUT ON/OFF option and its impact on queries on views such as v$sql and v$session. Here is the problem
Actually I define three variables in SQL*Plus in order to store sid, serial# and prev_sql_id columns from v$session in order to be able to use them later, several times in different other queries, while I'm still working in the current session.
So, here is how I proceed
SET SERVEROUTPUT ON; -- I often activate this option as the first line of almost all of my SQL-PL/SQL script files
SET SQLBLANKLINES ON;
VARIABLE mysid NUMBER
VARIABLE myserial# NUMBER;
VARIABLE saved_sql_id VARCHAR2(13);
-- So first I store sid and serial# for the current session
BEGIN
    SELECT sid, serial# INTO :mysid, :myserial#
    FROM v$session
    WHERE audsid = SYS_CONTEXT('UserEnv', 'SessionId');
END;
PL/SQL procedure successfully completed.
-- Just check to see the result
SQL> SELECT :mysid, :myserial# FROM DUAL;
    :MYSID :MYSERIAL#
       129   1067
SQL> Now, let's say that I want to run the following query as the last SQL statement run within my current session
SELECT * FROM employees WHERE salary >= 2800 AND ROWNUM <= 10;According to Oracle® Database Reference 11g Release 2 (11.2) description for v$session
http://docs.oracle.com/cd/E11882_01/server.112/e25513/dynviews_3016.htm#REFRN30223]
the column prev_sql_id includes the sql_id of the last sql statement executed for the given sid and serial# which in the case of my example, it will be the above mentioned SELECT query on the employees table. As a result, right after the SELECT statement on the employees table I run the following
BEGIN
    SELECT prev_sql_id INTO :saved_sql_id
    FROM v$session
    WHERE sid = :mysid AND serial# = :myserial#;
END;
PL/SQL procedure successfully completed.
SQL> SELECT :saved_sql_id FROM DUAL;
:SAVED_SQL_ID
9babjv8yq8ru3
SQL> Having the value of sql_id, I'm supposed to find all information about cursor(s) for my SELECT statement and also its sql_text value in v$sql. Yet here is what I get when I query v$sql upon the stored sql_id
SELECT child_number, sql_id, sql_text
FROM v$sql
WHERE sql_id = :saved_sql_id;
CHILD_NUMBER   SQL_ID          SQL_TEXT
0              9babjv8yq8ru3    BEGIN DBMS_OUTPUT.GET_LINES(:LINES, :NUMLINES); END;Therefore instead of
SELECT * FROM employees WHERE salary >= 2800 AND ROWNUM <= 10;for the value of sql_text I get the following value
BEGIN DBMS_OUTPUT.GET_LINES(:LINES, :NUMLINES);Which is not of course what I was expecting to find in v$sql for the given sql_id.
After a bit googling I found the following thread on the OTN forum where it had been suggested (well I think maybe not exactly for the same problem) to turn off SERVEROUTPUT.
Problem with dbms_xplan.display_cursor
This was precisely what I did
SET SERVEROUTPUT OFFafter that I repeated the whole procedure and this time everything worked pretty well as expected. I checked SQL*Plus documentation for SERVEROUTPUT
and also v$session page, yet I didn't find anything indicating that SERVEROUTPUT should be switched off whenever views such as v$sql, v$session
are queired. I don't really understand the link in terms of impact that one can have on the other or better to say rather, why there is an impact
Could anyone kindly make some clarification?
thanks in advance,
Regards,
Dariyoosh

Hi Dariyoosh,
SET SERVEROUTPUT ON has the effect of executing dbms_output.get_lines after each and every statement. Not only related to system view.
Here below what Tom Kyte is explaining in this page:
Now, sqlplus sees this functionality and says "hey, would not it be nice for me to dump this buffer to screen for the user?". So, they added the SQLPlus command "set serveroutput on" which does two things
1) it tells SQLPLUS you would like it <b>to execute dbms_output.get_lines after each and every statement</b>. You would like it to do this network rounding after each call. You would like this extra overhead to take place (think of an install script with hundreds/thousands of statements to be executed -- perhaps, just perhaps you don't want this extra call after every call)
2) SQLPLUS automatically calls the dbms_output API "enable" to turn on the buffering that happens in the package.Regards.

Parallelism in oracle using only one dual-core processor

Hi, is usefull or could i use parallel execution in oracle using only one dual core processor?
Can someone explain me why?

Hi
To take advantage of parallel processing you need enough resources (mainly CPU and I/O). If you run serially and the bottleneck is the CPU, then parallel processing might help. On the contrary, if the bottleneck is located in the I/O sub-system, throwing more CPU to it would not make things better. So, it's a question of balance between the CPU and I/O resources you have.

How to use Real time execution trace toolkit with Dual-core processor??

hi there
the situation as follows:
i have a computer (PC and Laptop) types with Dual-core processors, and am trying to do simulation using Multi-core technology and based on different simulation scenarios...starting from sequantial processing,.......Piple lining processing strategy. so that i can differentiate the time delay between those types of processing based on (Using 1 processor then dual-core processor Computers)
my question is: As i read through Ni's white papers i saw many notes refer to Real-time execution trace toolkit to investigate the (processing-time , etc) of multi-core processors in processing diffenent algorithms. My algorithms are to be run on 1 computer with dual-core processor BUT, not in real time environments, that is ( No hardware to be connected to my pc) only algorithms running on my pc....
So, is it possible to use Real time execution trace toolkit or anyother tools in LabVIEW to show processing-delays and/or anyother timing critical issues without using my application for real- time hardware.???
in other words: how to use Real time execution trace toolkit in non-hardware and/or real-time scenarios???
please help me in this.
Any suggestion, comments, feedback.....is absolutely highly appreciated
thanks a lot in advance
Labview Lover

Hey,
The Realtime Execution Trace Toolkit only works for NI RT Targets.
But you can use the Desktop Execution Trace Toolkit, just search for it under ni.com.

Uneven Core usage on dual core processor

Hi there
I noticed today whilst doing some video encoding (.TS files to .MP4) that my Mac Mini is not spreading the load over both of the cores in my dual core processor. Whilst Core 1 is showing nearly 100% Core 2 is hardly being used. Also I noticed that when the load on Core 1 dips then Core 2 will peak but as soon as the load goes back to Core 1 it will equally dip on Core 2 so essentially in Activity Monitor it looks like the core usage is a negative image of each other. The total CPU usage never peaked above 54%.
Could this an indication of a failing CPU or is it a case of poor core management? The software I've been using is VLC Player and also iMagiConverter.
Cheers
Jonty

What I don't understand is why software developers make software (especially video encoding that is all about CPU number crunching) that only utilises 50% of the CPU resources!
There are any number of possible reasons, from an application using a cross-platform code base that doesn't lend itself well to mulitiprocessor optimization for a particular platform, to inexperienced programmers who don't well understand programming for parallel threads, to developers who just want to crank out an application as quickly as they can (iMagiConverter seems to sort of fall into that category, given the number of applications of a similar nature that the "company" has produced). You'd have to get involved in the project development to know for sure.

Is a Pentium(R) Dual-Core processor good enough for Adobe Premiere Pro?

is a Pentium(R) Dual-Core processor good enough for Adobe Premiere Pro? Under system requirements, Adobe listed Intel Core Duo...not sure if this is just as good?

Hi Brian,
Good question. Keep in mind that these are minimum system requirements. I have not had a core 2 duo for some time, but I recall that the performance was not that good at that time, and this was CS5.5, or so. If you are going to use this machine, be sure to work at lower playback resolutions until you can afford a more powerful computer.
Video editors typically have more powerful systems than the minimum system requirements. Check our hardware forum for details: Hardware Forum

Hi Bernard,
Which version of McAfee are you using?
On my (personal) laptop, I'm using McAfee VirusScan 9.0.10. I don't frequently run JDeveloper on this laptop, but when I do, it's not experiencing signficant startup delays (it's a very low power machine: PIII 650 512Mb)
McAfee VirusScan seems to have very few configuration options (noticably different from Norton, which I use on my corporate desktop machine). I specifically remember changing the "File Types to Scan" option to "Program files and documents only". You can get to this by right clicking the "M" notification area icon, VirusScan->Options menu, Advanced button on the ActiveShield page.
In Norton, I think I have it configured so that it only scans files on write rather than on read. I also exclude directories which contain jdeveloper installs or other large Java apps (although scanning only on write elliminates most of the performance problems anyway and still leaves your system reasonably secure).
The easiest way to convince your MIS dept that the virus checker is the source of your problems might be if you ask them to allow you to turn it off in order to test the difference it makes to performance. It's a reasonable request to make if you're trying to elliminate possible causes for the slowdown (from the description you gave, it does sound like the AV upgrade is the first place I'd start looking).
If the virus checker is the source of your problems, you'll probably be seeing massive slowness in most large Java applications that have a large number of JARs on their classpath.
Thanks,
Brian

Turning on Virtualization in Compaq/HP Presario C500 with Dual Core processor

Hoping someone can help me out.
Running a Compaq Presario C500 laptop with the Dual Core processor. Intel's site says the processor supports virtualization.
However, in the F.24 A Phoenix BIOS setup (pressing F10 on Startup), there's no option to turn on Intel Virtualization Technology on any of the Tabs. Tried downgrading the BIOS to F.14A -- as the description says; "Adds item to Setup utility (F10) to enable/disable Intel Processor Virtualization Technology."
However, when I startup, press F10 -- there's no option for turning this on.
Is there another place to go -- other than the F10 setup area of the BIOS -- to turn on Virtualization Technology?
If an expert out there can help, it would be very appreciated!
