Core i7-4820K


Description
We need your help: we don't have results in all modes. If you have a i7-4820K and want to help us to complete the stats, you just have to run the benchmark in modes FPU, SSE, and validate the results. You don't have to register and the whole process will take less than 3 minutes per mode.

The Core i7-4820K is a cpu manufactured by Intel that was released on September 2013. This model has 4 Ivy Bridge -E cores with HyperThreading, runs at 3700 MHz as base frequency and has a a thermal design power of 130 W.

The i7-4820K has 32+32 kB of cache L1, 256 kB of cache L2 and 8192 kB of cache L3.

"Ivy Bridge is the last Intel microarchitecture for which there is official driver support for Windows XP . It is made under 22 nm Tri-Gate transistor (""3D"") technology and is basically a Sandy Bridge shrink. It has PCI Express 3.0 support and RdRand instruction for security tasks."

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.
