Mid Quality Performance
Since our evaluation so far has been focused on performance with Star Swarm’s most resource intensive Extreme setting, we wanted to shake things up by trying a lower quality setting.
In this case Star Swarm’s various quality levels adjust both the CPU and GPU workload, with the Mid quality setting reducing both the number of draw calls generated and the amount of work generated per frame for the GPU. As a result we’re not adjusting just the CPU or the GPU workload, but it can give us an idea of what to expect from DirectX 12 and Star Swarm at lower settings more suitable for weaker systems.
Even with this lower quality setting, the CPU results tell us that only the GTX 980 is truly CPU bottlenecked with 2 cores. Everything else from the 290X on down can reach its GPU limit with a relatively weak CPU.
Overall the numbers are different, but the lineup is the same whether it’s Extreme quality or Mid quality. Every vendor still sees massive gains from enabling DirectX 12, though the overall gains aren’t quite as great as with Extreme quality. Meanwhile GTX 750 Ti in particular continues to see the weakest gains from DirectX 12, at only 14% for a 2 core configuration, thanks to a combination of NVIDIA’s lower CPU consumption and earlier GPU bottleneck.

??? Eh? The computer, with DX12, is working harder AND offering better results.bitcrazed - Saturday, February 7, 2015 - link
Windows 7 will remain in broad use in businesses for a while yet, but given that Win10 will be a free upgrade for everyone else means that we should see far faster upgrades to Win10 than prior OS'.Put it this way - who here with a gaming rig or a machine they game on regularly is going to say - "No, I don't want a free upgrade to this new fangled Win10 + DX12 nonsense - I prefer to play my games at 10 fps and to gradually fade into obscurity"?

Gamers also seem to upgrade at a much faster rate. windows 8+8.1 make up 30% of steam windows users, while they only make up 12% of the general market. given that its FREE, windows 10 will probably become very popular very quickly.wolrah - Saturday, February 7, 2015 - link
Why would you say that? Windows 10 will be a free upgrade for anyone on a DX11 compatible system and so far has been a great OS to use. At the moment there's literally no reason not to upgrade.If Microsoft doesn't screw it up and the users aren't change-hating morons about it, Windows 7 and 8 should be fading memories in a year or two as far as the gaming community is concerned. Corporate users will still be themselves and be slower to upgrade, but corporate users' relevance to new gaming APIs is minimal.

Another stab at Valve and their SteamOS.OpenGL NG is quite a bit away and this will likely make Linux lag behind Windows in gaming again. For now.
Also with Xbox for Windows 10 I assume they may have some competition (which is likely why they wanted to migrate to Linux in the first place, because app-stores on any OS have become the standard.)

I'd like to see an integrated graphics version of this. Intel and AMD APU. If you're feeling fiesty, an AMD APU with a second card in Crossfire.Question I would have in an APU related article. With APUs, does it now make even more sense to go with higher bandwidth RAM? Some suggestions for the CPUs: AMD 7850K (duh), AMD A-6, AMD A-8, Haswell (Intel 7, 5, and 3 plus a crappy Pentium), AMD Kabini (top sku), and the Crystalwell Pro.
I think this has big mobile implications. I'd like to see a choice of a performance cap at 30-60 fps and the remainder of what's left on the table delivered in less heat and longer battery life.

what do you mean under windows 10; are you talking about windows 7 or even windows 8.1 ?tviceman - Friday, February 6, 2015 - link
Ryan I appreciate the depth and analysis of all your reviews. Anandtech is always my first stop for analysis of new video cards and tablets. That said, the continued tardiness of the GTX 960 review, as well as the lack of any 970 memory performance investigations is really disheartening. Especially the 960, since it's now 2 weeks today since the NDA was lifted.Keep up the analysis, and hire extra help if needed. ;)

Uhm, they had an article on the 970 memory issues:http://anandtech.com/show/8935/geforce-gtx-970-cor...

They did have an article, but they didn't do any extensive investigations into performance when going over 3.5gb but staying within 4gb.
