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 ESTOffice Performance
The dynamics of CPU Turbo modes, both Intel and AMD, can add a wrinkle to testing in environments with a variable threaded workload. There is also an added issue of the motherboard remaining consistent, depending on how the motherboard manufacturer wants to add in their own boosting technologies over the ones that Intel would prefer they used. In order to remain consistent, we implement an OS-level unique high performance mode on all the CPUs we test which should override any motherboard manufacturer performance mode.
All of our benchmark results can also be found in our benchmark engine, Bench.
Dolphin Benchmark: link
Many emulators are often bound by single-threaded CPU performance, and general reports tended to suggest that Haswell provided a significant boost to emulator performance. This benchmark runs a Wii program that raytraces a complex 3D scene inside the Dolphin Wii emulator. Performance on this benchmark is a good proxy of the speed of Dolphin CPU emulation, which is an intensive single core task using most aspects of a CPU. Results are given in minutes, where the Wii itself scores 17.53 minutes.
Crystal Well doesn’t help much in Dolphin, indicating it is more CPU frequency limited than DRAM/cache limited.
WinRAR 5.0.1: link
Our WinRAR test from 2013 is updated to the latest version of WinRAR at the start of 2014. We compress a set of 2867 files across 320 folders totaling 1.52 GB in size – 95% of these files are small typical website files, and the rest (90% of the size) are small 30 second 720p videos.
WinRAR is our typical benchmark to go to when testing whether DRAM is factor, and the improvements provided by the Crystal Well implementation trump any frequency deficit.
3D Particle Movement
3DPM is a self-penned benchmark, taking basic 3D movement algorithms used in Brownian Motion simulations and testing them for speed. High floating point performance, MHz and IPC wins in the single thread version, whereas the multithread version has to handle the threads and loves more cores.
3DPM, like Dolphin, is concerned more with CPU frequency than DRAM accesses.
FastStone Image Viewer 4.9
FastStone is the program I use to perform quick or bulk actions on images, such as resizing, adjusting for color and cropping. In our test we take a series of 170 images in various sizes and formats and convert them all into 640x480 .gif files, maintaining the aspect ratio. FastStone does not use multithreading for this test, and results are given in seconds.
Web Benchmarks
On the lower end processors, general usability is a big factor of experience, especially as we move into the HTML5 era of web browsing. For our web benchmarks, we take four well known tests with Chrome 35 as a consistent browser.
Mozilla Kraken 1.1
WebXPRT
Google Octane v2
In the webtests, the Broadwell-DT CPUs didn’t necessarily take top spot but they are punching above their expected weight for their frequency.

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.
