Linux Performance
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.
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 strong developer base, but also relies heavily on memory bandwidth as well as CPU performance.

You could have saved some money by not ordering a CPU on the very first day of availability. Other than that, there is no downside to having a 6800K instead of a 5820K, its just not vastly faster.ezcameron76 - Tuesday, May 31, 2016 - link
What would have been the difference in getting it say next week or at what time would you say would be better. I have to have the PC build by this Thursday so didn't have the time but I wouldn't think the price would change in a short amount of time.ShieTar - Tuesday, May 31, 2016 - link
About 50$ I assume. Don't know how to find this info for the US, but in Germany prices have dropped by 30€ from yesterday to today:http://geizhals.eu/?phist=1394467

I paid $450 on neweggezcameron76 - Tuesday, May 31, 2016 - link
My question is should I return the 6800k for the 5820k as it will overclock better or no?ShieTar - Wednesday, June 1, 2016 - link
Not really, the first 10% of better OC will be wasted on compensation of the IPC improvement anyways. And with virtually no CPU-limited games out there, you don't really need to OC anyways.TEAMSWITCHER - Tuesday, May 31, 2016 - link
I'm not sure. Most of the reviews are overclocking the 10-core 6950X. I'm wondering if there will be some sweet 6-core parts (6800K and 6950K) that overclock great because the four disabled cores are used separate the six functional cores. I'm speculating that having active cores separated by inactive cores might help to impede thermal accumulation.It's a funny thought I had today, but I don't know of any way to find out which cores are disabled.

Where the heck is the GTX 1080 review?It's been weeks since the NDA was lifted on it and now with the NDA lifted on the GTX 1070 nothing again.
Since there was time to do this review excuses about not enough time to do a proper review won't hold water.

For a mere $4,115, why not order a 22 core Xeon? :-Dhttp://ark.intel.com/products/91317/Intel-Xeon-Pro...
