Linux, different processors

I have Linux running on two diffeerent processors

E7-4890 v2 

E7- 8870

Open in new window


What are the differences between these two processors other than clock speed.

Based on what I have seen, I suspect the 4890 performance is enhanced by other factors than simply clock speed

Thanks

I don't see the 4890 on Intel's site.

There is a E7-4870: http://ark.intel.com/products/53579
and it's about the same as E7-8870: http://ark.intel.com/products/53580/Intel-Xeon-Processor-E7-8870-30M-Cache-2_40-GHz-6_40-GTs-Intel-QPI

except the fact that the big brother (8870) supports an 8-CPU configuration and double max RAM (4TB vs 2 TB).

HTH,
Dan

The amount of cores/threads is different (10/20 for 8870 and 15/30 for 4890v2).
