Is the 9950X3D capable of handling a full CPU workload and gaming?
If the application consumed 100% of the CPU initially, running a video game should allow the 9950X3D to manage resources effectively. The game will utilize its cores with vcache while the other application continues using all cores.
There are utilities such as process lasso or process hacker that let you adjust settings yourself when Windows, app, or game behaves undesirably.
The approach depends on the software's design; some applications that consume full CPU power have high priority, so even if the game runs on cache cores it would still perform poorly due to excessive CPU usage.
You need to configure affinity and priority for those elements that don't function as expected. (same applies for Intel with e-cores)
The application is Handbrake with the x265 encoder. I play main games like World of Warcraft Classic and Star Wars The Old Republic during encoding. I set the encoding to run two tasks at once because x265 doesn't fully utilize all threads. I can choose to use only the vcache cores, but Handbrake will still use them all. Games that are very CPU-intensive won't work well with Handbrake running. Most reviews I've seen mention people using this CPU for gaming and productivity, but the GPU handled it. None of them had an app or task using 100% CPU while playing a game. I prefer not to follow the usual setup of 8 cores for the game and 8 cores for the app.
I rarely play games but have tested and compared Handbrake a lot. I noticed H.265 uses over 85% CPU for 4K UHD files, around 50-60% for HD. HD works best with Process Lasso and one thread per core. Without that setup, Handbrake often assigns multiple threads per core, which slows performance compared to the single-thread-per-core method. Others mention various ways to manage Handbrake usage, especially for CPU-heavy games—avoiding concurrent encodes if they’re intense.
If every core is operating at full capacity, then playing any game won't perform well. It's not that complicated. What's your current CPU, if you have a PC? You might want to avoid heavily loading the CPU with tools like Handbrake or OCCT and then try running a game. The issue will still arise. Just because the processor has a 9950x3d doesn't mean it's significantly different from other CPUs in this regard. The same applies here. When cores are focused on one task, they reach their maximum capacity and can't allocate more resources to a game.
