Xeon E5-4640


Performance
623k points

Description
The Xeon E5-4640 is a cpu manufactured by Intel that was released on May 2012. This model has 8 Sandy Bridge-EP cores with HyperThreading, runs at 2400 MHz as base frequency and has a a thermal design power of 95 W.

"Sandy Bridge codename was originally ""Gesher"". The development began in 2005 and four years later, the first Sandy Bridge CPU was presented. The most prominent features are Intel Turbo Boost 2.0, AES encryption and SHA-1 hashing acceleration, Advanced Vector Extensions (AVX) 256-bit instruction set and the ability to have up to 8 physical cores or 16 logical cores through Hyper-Threading."

Non-optimized benchmark
The benchmark in Mode 0 (FPU) measures cpu performance with non-optimized software. It uses the basic µinstructions from the i386 architecture with the i387 floating point unit. This mode is compatible with all CPUs so it's practical to compare very different CPUs

Monothread performance graph
Monothread performance graphics gives the performance vs time. They are useful to measure the time it takes to the CPU to reach the maximum performance.

Usually, CPU's performance will be steady during these tests but if it has a slow frequency strategy, the first samples will show a lower score.

Multithread performance graph
Multithread graphs measure the performance against a heavy load during certain time.

If CPU's TDP doesn't limit the frequency and the machine is properly cooled, performance should remain steady vs time. Otherwise, the performance score will oscillate or decrease over time.
