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.

Can G3260 run the latest games that require quad core CPU?wallysb01 - Tuesday, June 2, 2015 - link
What is ‘good enough’ performance though? I put a G3220 pentium in my wife’s computer and its plenty good enough for everything she does, which I suspect represents 99.8% of the population (Microsoft office stuff, email, facebook and Netflix/Amazon prime). Heck I can even play DOTA2 on it reasonably well.Intel has had ‘good enough’ graphics for damn near everyone for a while now and that G3220 was like $55 on sale. To me ‘good enough’ graphics isn’t playing modern games at high resolution and quick frame rates. If you want an iGPU to do that, you should expect to pay for it since you’re in the <0.1% of the population that cares.

"Truth is (as pointed out) you can get an AMD chip with a $100 discrete graphics card which would blow either of the iGPUs away."Or you can compare that AMD chip and DGPU combo with an even cheaper Intel Pentium and same DGPU combo... :)

Give it a generation or two - the cost of eDRAM will fall dramatically once Intel starts shipping it in millions of CPUs.Refuge - Tuesday, June 2, 2015 - link
They have proven they can build it, but at that price it is a bit of a moot point ATM.First lets see the price of these iGPU's come down before we count it a success.

This who multipart review is slightly alarming...On the CPU itself: an IVB repeat: very minor CPU improvements, large GPU upgrade...
Oh, btw, since the CPUs are unlocked, can we get some identical speed benchmarks? Would be the nicest, easiest way to track IPC and eDRAM improvements.

The article mentioned them having problems with Beta Firmware stopping them from having overclocking and iGPU comparisons in this email.ZeDestructor - Wednesday, June 3, 2015 - link
I know. I feel that they should have pushed an early article out explaining the issues and published the review later on in one piece. You don't give good firmware, you get later coverage.vFunct - Tuesday, June 2, 2015 - link
The MSI page takeover ads here leave ZERO margins from the text..Ryan Smith - Tuesday, June 2, 2015 - link
On it. Sorry about that.
