Standard 'D-Series' on Linux VM

Question

Hi,
Looking at the pricing and descriptions, I find here:
http://azure.microsoft.com/en-us/pricing/details/virtual-machines/#Linux
that the D-Series is meant to be 60% faster CPU.
However I find that in my linux VM, an A3-Series VM outputs this information (for all 4 cores):
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 45
model name      : Intel(R) Xeon(R) CPU E5-2660 0 @ 2.20GHz
stepping        : 7
microcode       : 0xffffffff
cpu MHz         : 2194.705
cache size      : 20480 KB
physical id     : 0
siblings        : 4
core id         : 0
cpu cores       : 4
apicid          : 0
initial apicid  : 0
fpu             : yes
fpu_exception   : yes
cpuid level     : 13
wp              : yes
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss ht syscall nx lm constant_tsc rep_good nopl eagerfpu pni pclmulqdq ssse3 cx16 sse4_1 sse4_2
popcnt aes xsave avx hypervisor lahf_lm xsaveopt
bogomips        : 4389.41
clflush size    : 64
cache_alignment : 64
address sizes   : 42 bits physical, 48 bits virtual
power management:
And a D-Series VM outputs exactly the same cpuinfo.
Why isn't the VM identifying a higher level CPU?
Thanks

Answer 1

Hi Ricardo;
You are getting the model name  : Intel(R) Xeon(R) CPU E5-2660 0 @ 2.20GHz” for your A-series VM, because your VM resides on hardware that is supposed to be for D-series. Azure does this to for easier transition and movement
towards scalability.
However that doesn’t mean you would get the processor speed of D-series, because the processor speed will be throttled down to match A-series.
Warm Regards;
