The Intel 6th Gen Skylake Review: Core i7-6700K and i5-6600K Tested

Built around several freely available benchmarks for Linux, Linux-Bench is a project spearheaded by Patrick at ServeTheHome to streamline about a dozen of these tests in a single neat package run via a set of three commands using an Ubuntu 11.04 LiveCD. These tests include fluid dynamics used by NASA, ray-tracing, OpenSSL, molecular modeling, and a scalable data structure server for web deployments. We run Linux-Bench and have chosen to report a select few of the tests that rely on CPU and DRAM speed.
C-Ray: link
C-Ray is a simple ray-tracing program that focuses almost exclusively on processor performance rather than DRAM access. The test in Linux-Bench renders a heavy complex scene offering a large scalable scenario.
NAMD, Scalable Molecular Dynamics: link
Developed by the Theoretical and Computational Biophysics Group at the University of Illinois at Urbana-Champaign, NAMD is a set of parallel molecular dynamics codes for extreme parallelization up to and beyond 200,000 cores. The reference paper detailing NAMD has over 4000 citations, and our testing runs a small simulation where the calculation steps per unit time is the output vector.
NPB, Fluid Dynamics: link
Aside from LINPACK, there are many other ways to benchmark supercomputers in terms of how effective they are for various types of mathematical processes. The NAS Parallel Benchmarks (NPB) are a set of small programs originally designed for NASA to test their supercomputers in terms of fluid dynamics simulations, useful for airflow reactions and design.
Redis: link
Many of the online applications rely on key-value caches and data structure servers to operate. Redis is an open-source, scalable web technology with a b developer base, but also relies heavily on memory bandwidth as well as CPU performance.

I'm not a hardcore gamer but when I'm GPU rendering with CUDA my whole UI slows to a crawl and I can hardly move windows. A passable GPU built in would let me use my NVidia cards for CUDA while freeing my CPU integrated graphics for windowing.lilmoe - Wednesday, August 5, 2015 - link
Just wondering, have you tried that very scenario in Windows 10? Please do. I'm assuming you're using Windows 7 since I've had the same problem. But even with 100% GPU utilization, Windows 10 has been very responsive in comparison, at least for me.Flunk - Wednesday, August 5, 2015 - link
They're on a die anyway, just cut down. Which makes it a really stupid waste.extide - Thursday, August 6, 2015 - link
No, the 48EU versions are separate dies than the 24EU versions.Beaver M. - Wednesday, August 5, 2015 - link
Wrong. Some games use the L4 cache, and you can see the increase in performance clearly. Also think about that the Broadwell is running lower clock speed.Skylake is a joke, if you open your eyes.

GT2 WILL NEVER BEAT GT3e graphics. It is all about those EU'S and GT2 just does not have enough of them... More L4 Cache would help, but it will not be enough.Beaver M. - Wednesday, August 5, 2015 - link
I am talking about L4 being used and increasing framerates even if the IGP is not being used. You can see it clearly in the benchmarks.Refuge - Wednesday, August 5, 2015 - link
Then it sounds like you want the CPU with Crystalwell memory, but no iGPU.Beaver M. - Wednesday, August 5, 2015 - link
I am talking about what is there right now. Skylake is supposed to be an upgrade, yet Broadwell wipes the floor with it in many cases because of that L4, even with lower clock speeds.fokka - Wednesday, August 5, 2015 - link
there will also be skylake chips with l4 cache.
