The Intel Broadwell Desktop Review: Core i7-5775C and Core i5-5675C Tested (Part 1)
by Ian Cutress on June 2, 2015 7:45 AM ESTProfessional Performance: Linux
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.
Due to our limited testing time and other issues, only the i7-5775C was processed in our Linux tests. These should be updated for Part 2.
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.

Not really sure how appealing this will be for anyone on LGA1150 for the desktop, given Skylake is just around the corner. Certainly more appealing to heavy duty laptops, maybe NUCs for the better GPU capabilities but the prices are too high compared to low-end CPU + dGPU options (Alienware Alpha at $400-500 comes to mind).CuriousBeing - Tuesday, June 2, 2015 - link
I could never understand why the FX-8350/FX-8370 are never used in these benchmarks....Refuge - Tuesday, June 2, 2015 - link
It is probably because of the new test setup. They haven't re-run everything yet.Not that I consider that a good excuse, I know they are busy though and it is an answer to your question at least if that helps. :P

Broadwell is not for users who want high integrated GPU performance or something like thatIt's an upgrade root for many with Haswell

Ian, buddy, you really need to step up your game when it comes to analyzing power, temperature, and noise. Seriously, Anandtech used to be a place where you could read a review on a product and have all the information you needed about it and now once i'm done reading an Anandtech review i have to look elsewhere to get the full story.Old Anandtech: Comprehensive and comprehensible.
New Anandtech: Comprehensible only because the reviews have become utterly incomprehensive.
Step it up buddy.

A bit harsh, but agree with the point. I'm now waiting (hoping) that somebody at Ars or TPU gives a more comprehensive review.This Delta power consumption shit has to go as well.

So the actual CPU part takes up less than half the die. My forehead cannot take much more of this, there are just to many facepalms these days.And this is what they want us to pay $276 for - a CPU that would take up much less than 100 mm2 and should cost $100.
God, please, let Zen be a good CPU, please. I will pray every day, I want Haswell to be my last Intel CPU for a long time.
I would just like to point out, than an i3 with a 750 Ti will destroy this APU, offering PS4 performance in every single game, for pretty much the same cost.

Don't expect Zen to be a some "cheap chip" AMD has stated they're going to focus on performance rather than cost. I'm expecting Zen with HBM to cost as much as comparable Intel offerings.Rather than complaining about the cost of new cutting edge hardware, put your money where your mouth is and get the i3 + 750TI. I have one here and it serves well as a secondary machine (as well as a doorstop). I'd much rather use my 2500K + 960...

I'd really love to see benchmarks of Civilization V on this thing. With such a CPU-intensive game, it'd be interesting to see how much the L4 cache makes an impact, not just with integrated graphics, but also when using dedicated graphics, to see how much the L4 cache helps the raw CPU performance in a game that is so easily CPU-constrained...Peichen - Tuesday, June 2, 2015 - link
I think Civ 5 is still single thread or maybe dual thread and have to process everything in order so each term still take minutes. I have the game at launch and all packs & DLCs and it doesn't stress my overclocked 3770K a bit. No core hits above 40% yet a term still takes forever. The game isn't 64-bit either so there is also that.
