Intel Xeon E5-4650 v2 vs. Intel Xeon E5-4650 v4 Specs & Speed Benchmarks

CPU Speed

These tests are designed to stress the CPU components of the processor

Memory Bandwidth (GB/Sec), Higher is better


Performance/Price (Value)

Some of the same tests as above, but shown as a relation to the price. This shows what performance you get for each additional dollar spent. The higher the score, and the more value you get for your money
