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.

Who needs to wait for DX12? Mantle is running great for me right now. :)sireangelus - Sunday, February 8, 2015 - link
would you do one quick test using an 8core fx?johnny_boy - Sunday, February 8, 2015 - link
Would have loved to see this, and some lower end CPUs even.editorsorgtfo - Sunday, February 8, 2015 - link
What about threaded CPUs ? for example 1 core 2 threads old pentium CPUs and 2 cores 4 threads i3 CPUs ? can you still count that them as 2 cores and 4 cores ?
I wanna ask this on the anandtech comment section but I don't have an account there XD

What I care about are great graphics. It is a shame there is no Crytek 4 engine to show off what DX12 could do. MS should have hired the original crytek developers to create some showpiece game.Gigaplex - Monday, February 9, 2015 - link
The API won't really change what you can do compared to DX11 other than reduce some system requirements. The feature levels are what provides new eye candy, and this preview doesn't cover that aspect. Wait until it hits retail, you'll probably see some fancy tech demos.Thermalzeal - Sunday, February 8, 2015 - link
I have one big question to ask.Since Direct X12 is resulting in significant performance gains, what is the potential for these improvements to translate over to the Xbox One? While I'm sure the Xbox One already has some of these bare metal improvements, due to the focus of the device...is it possible that DX12 will make the Xbox One more powerful than the PS4?

"Since Direct X12 is resulting in significant performance gains, what is the potential for these improvements to translate over to the Xbox One?"Only Microsoft really knows the answer to that one. But I would be shocked beyond belief if the XB1's D3D 11.X API didn't already implement many of these optimizations. It is after all a fixed console, where low-level APIs have been a mainstay since day one.
"is it possible that DX12 will make the Xbox One more powerful than the PS4?"
In a word, no. The best case scenario for Microsoft is that Sony implements their own low-level API (if they haven't already) and we're back at square one. APIs can't make up for hardware differences when both parties have the means and influence to create what would be similar APIs.
