It’s been in development for a long time, with much thought put into supporting all the goodness of the CPU cores in today’s PCs.īut not all games are going to be Ashes of the Singularity, even if they carry the DirectX 12 label. Gears of War Ultimate Edition PerformanceĪshes of the Singularity is probably a best-case scenario for DirectX 12. I threw the latest Ashes of the Singularity beta benchmark at our 8-core rig to find out how many cores we’ll need for DX12 gaming.
A few games will overload that dual-core with physics or even audio chores, but a good dual-core with Hyper-Threading still works for many people in the vast majority of games today. In today’s conventional wisdom, that’s correct for most games. As you can see in the chart below, you pretty much top out at a dual-core with Hyper-Threading. That’s a bit of a bummer, but at least it’s better than the results for the same tests using DirectX 11. Adding Hyper-Threading and more cores made no difference.įutureMark’s API overhead feature test seems to top out at fewer cores than we expected. Unfortunately, it hits a wall at about six cores. 3DMark’s feature test shows DirectX 12 scales very nicely as you add Hyper-Threading and and core counts. This time, with an eight-core rig up and running, the results are far more interesting. Last year, unfortunately, I didn’t have an eight-core chip available and had to settle for quad-core numbers. These are tests of DirectX 12 performance differences between various thread counts and clock speeds on simulated CPUs. T he chart below pretty much proves that cores matter more than clock speed.
This was one of the first showcases for all that is possible with DirectX 12, and when I tested it last year I found that a quad-core with Hyper-Threading paid huge dividends over a dual-core.
It’s not about gaming but it shows how some workloads will climb for the stars.Ĭinebench R15’s rendering test, though, is a pure CPU test. What about gaming? For that, I first turned to 3DMark’s API overhead test. It doesn’t scale forever, as I discovered when testing the Falcon Northwest Tiki, but here with a “mere” eight cores, it climbs for the stars.Ĭinebench R15 is a 3D rendering benchmark that likes a ton of CPU cores thrown at it. It’s a great real-world benchmark that gives you an idea of how more threads could pay off. The first test I ran was Maxon’s Cinebench R15.
