Ashes of the Singularity Escalation
Seen as the holy child of DirectX12, Ashes of the Singularity (AoTS, or just Ashes) has been the first title to actively go explore as many of DirectX12s features as it possibly can. Stardock, the developer behind the Nitrous engine which powers the game, has ensured that the real-time strategy title takes advantage of multiple cores and multiple graphics cards, in as many configurations as possible.
As a real-time strategy title, Ashes is all about responsiveness during both wide open shots but also concentrated battles. With DirectX12 at the helm, the ability to implement more draw calls per second allows the engine to work with substantial unit depth and effects that other RTS titles had to rely on combined draw calls to achieve, making some combined unit structures ultimately very rigid.
Stardock clearly understand the importance of an in-game benchmark, ensuring that such a tool was available and capable from day one, especially with all the additional DX12 features used and being able to characterize how they affected the title for the developer was important. The in-game benchmark performs a four-minute fixed seed battle environment with a variety of shots, and outputs a vast amount of data to analyze.
For our benchmark, we run a fixed v2.11 version of the game due to some peculiarities of the splash screen added after the merger with the standalone Escalation expansion, and have an automated tool to call the benchmark on the command line. (Prior to v2.11, the benchmark also supported 8K/16K testing, however v2.11 has odd behavior which nukes this.)
At both 1920x1080 and 4K resolutions, we run the same settings. Ashes has dropdown options for MSAA, Light Quality, Object Quality, Shading Samples, Shadow Quality, Textures, and separate options for the terrain. There are several presents, from Very Low to Extreme: we run our benchmarks at Extreme settings, and take the frame-time output for our average, percentile, and time under analysis.
All of our benchmark results can also be found in our benchmark engine, Bench.

Anyone having an issue with Bench? I'm trying to compare my i7-3770k to the i7-8700k and it comes back with no data. Same with trying the Threadripper 1920xmkaibear - Friday, October 6, 2017 - link
CPU tests changed so benchmarks weren't comparable. Latest processor tested on the old tests was the 7700K iirc, and not everything is tested on the new tests.I'd compare results for the 3770k and the 2600K to get a baseline then you can compare 2600K to the 8700K. It's a bit fiddly, I have to do the same with my 4790K.

We updated our CPU testing suite for Windows 10 in Q1. Regression testing is an on-going process, though it's been slow because of all the CPU launches this year. Normally we have 1/2 a year. We're so far at what, 6 or 7 for 2017?mczak - Thursday, October 5, 2017 - link
Doesn't look to me like the die size actually increased at all due to the increased gate pitch.The calculations in the article forgot to account for the increase of the unused area (at the bottom left) - this area is tiny with 2c die, but increases with each 2 cores added significantly. By the looks of it, that unused area would have grown by about 2 mm^2 or so going from 4 to 6 cores, albeit I'm too lazy to count the pixels...

Your conclusion is weirdest thing ever, you fully ignore the 8359k and AMD.In retail, the 8350k will do very very well and retail is what matters for most readers
And ignoring AMD is not ok at all, it's like you think that we are all idiots that buy on brand.You do think that, your system guides make that very clear but you should not accept, support and endorse such an idiotic behavior.
AMD got hit hard here, Intel takes back the lead and it's important to state that. Sure they might have Pinnacle Ridge in a few months and take back the lead but buyers that can't wait should go with Intel right now, for the most part. AMD could also adjust prices ofc.

Really confused why the pricing listed in this review isn't consistent- for Intel you were posting prices you found online, but for Ryzen you appear to be posting MSRP.The truth is- you can find 1700x for $298 right now EASILY (Amazon), yet Microcenter is selling the 8700k for $499.
If you factor this information in, the AMD solutions are still far more valuable per dollar.

I really can’t belive the amount of flak Anandtech takes these days. I find it un-earned an unwarrented. Out of all the tech sites and forums I manage to read in a given week, Anandtech is the most often quoted and linked to. Hell I use it as my go to for reference and comparison (and general reading). My only big complaint is your ads, and I’d gladly pay a sub to completely remove that nonsense and directly support the site!Ian, you and your staff deserve far more credit than you get and that’s an injustice. Each piece is pretty thorough and pretty spot on. So for that thank you very much.
This article is no exception to the rule and is superb. Your graph layouts are a welcome feature!!!!! I look forward to your ever expanding tests as new chips roll in. I think the 8600k is going to be a game changer in the i5 vs i7 performance category for these hexacore cpus. I think that’s why almost all the reviews I’m reading today are with the 8700k and 8400.
Agin, thank you and your staff very much for the work you put into publishing amazing articles!!

Personally I buy whatever is best at the time. Right now I'm typing this on a 1700x and I can see a 4770k build on the desk next to me. So it's always funny to see the bias. Intel review gets posted, AMD fanboys come out of the wood works to trash them as paid shills. But it works exactly the same on any positive AMD reviews. Intel fans come in trashing them. It's really odd. Anandtech is one of the most unbiased sites I've found and I trust their reviews implicitly.mkaibear - Saturday, October 7, 2017 - link
> Anandtech is one of the most unbiased sites I've found and I trust their reviews implicitly.Yep. Anyone who looks at AT and sees bias needs to examine their own eyesight.

For the H.264 encoding tests, you could consider using the "medium" preset or better. The "very fast" preset has a tendency to use fewer cores.
