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.

Hmm ... rather disappointing that Anandtech did not include Ryzen 1600/X until called out by astute readers.mkaibear - Friday, October 6, 2017 - link
...apart from including all the data in their benchmark tool, which they make freely available, you mean? They put in the CPUs they felt that were most relevant. The readership disagreed, so they changed it from their benchmark database. That level of service is almost unheard of in the industry and all you can do is complain. Bravo.Koenig168 - Friday, October 6, 2017 - link
Irrelevant. While I agree with most of what you said, that does not change the fact that Anandtech did not include Ryzen 1600/X until called out by astute readers. To make things a little clearer for you, the i7-8700 is a 6C/12T processor. The Ryzen 1600 is a 6C/12T processor. Therefore, a comparison with the Ryzen 1600 is relevant.You should have addressed the point I made. Instead all you can do is complain about my post. Bravo. (In case this goes over your head again, that last bit is added just to illustrate how pointless such comments are.)

So your point is, in essence, "they didn't do what I wanted them to do so they're damned for all time".They put up the comparison they felt was relevant, then someone asked them to include something different - so they did it. They listened to their readers and made changes to an article to fix it.
Should they have put the R5 in the original comparison? Possibly. I can see arguments either way but if pushed I'd have said they should have done - but since even the 1600X gets beaten by the 8400 in virtually every benchmark on their list (as per https://www.anandtech.com/bench/product/2018?vs=20... they would then have been accused by the lurking AMD fanboys of having picked comparisons to make AMD look bad (like on every other article where AMD gets beaten in performance).
So what are you actually upset about? That they made an editorial decision you disagree with? You can't accuse them of hiding data since they make it publicly accessible. You can't accuse them of not listening to the readers because they made the change when asked to. Where's the issue here?

OK on further reading it's not "virtually every" benchmark on the list, just more than half. It's 50% i5 win, 37% R5 win, 12% tied. So not exactly a resounding triumph for the Ryzen but not as bad as I made it out to be.In the UK the price differential is about £12 in favour of the i5, although the motherboard is about £30 more expensive (though of course Z370 is a lot more fully featured than B650) so I think pricing wise it's probably a wash - but if you want gaming performance on anything except Civ VI then you'd be better off getting the i5.
...oh and if you don't want gaming performance then you'll need to buy a discrete graphics card with the R5 which probably means the platform costs are skewed in favour of Intel a bit (£25 for a GF210, £32 for a R5 230...)

As mentioned when I first called out this omission, I would think comparing a 6 vs 4 core irrelevant. This is what AnandTech recommended to lookout for on page 4 "Core Wars": Core i5-8400 vs Ryzen 5 1500X.You be the judge if this makes sense when there is a far better competition/ comparison between the i5 8400 vs R5 1600. Only when you go reading around and you realized that hey, the i5 8400 seems to be losing in some areas to the 1600. I give AnandTech the benefit of the doubt, so I am done debating what is relevant or not.

The Anandtech benchmark tool confirms what Ryan indicated in the introduction: the i7-8700k wins against the 1600X across the board, due faster clocks and better IPC. The comparison to the i5-8400 is more interesting. It either beats the 1600X by a hair, or loses rather badly. I think the issue is the lack of hyperthreading on the i5-8400 makes the 1600X the better all-around performer. But if you mostly run software that can't take advantage of more than 6 threads, then the i5-8400 looks very good.Personally, I wouldn't buy i5-8400 just because of the socket issue. Coffee Lake is basically just a port of Skylake to a new process, but Intel still came out with a new socket for it. Since I don't want to dump my motherboard in a landfill every time I upgrade my CPU, Intel needs a significantly superior processor (like they had when they were competing against AMD's bulldozer derivatives) to convince me to buy from them.

So Intel still isn't getting their head out of their rear and offering the option of a CPU that trades all the integrated GPU space for additional cores? Moronic.mkaibear - Friday, October 6, 2017 - link
Integrated graphics make up more than 70% of the desktop market. It's even greater than that for laptops. Why would they sacrifice their huge share of that 70% in order to gain a small share of the 30%? *that* would be moronic.In the meantime you can know that if you buy a desktop CPU from Intel it will have an integrated GPU which works even with no discrete graphics card, and if you need one without the integrated graphics you can go HEDT.
Besides, the limit for Intel isn't remotely "additional space", they've got more than enough space for 8/10/12 CPU cores - it's thermal. Having an integrated GPU which is unused doesn't affect that at all - or arguably it gives more of a thermal sink but I suspect in truth that's a wash.

We need a completely new PC architecture - you need more CPU cores - add more CPU cores, you need more GPU cores add more GPU cores, all of them connected via some sort of Infinity fabric like bus and sharing a single RAM. That should be possible to implement. Instead of innovating Intel is stuck in the current 80s architecture introduced by IBM.
