The cores in the second CCD only get 32 MB.
There won’t be any latency issues, either, as there is no other CCD to communicate with.
Game Mode must be enabled and the Xbox Game Bar needs to be up to date, too.
All test systems were configured with aGeForce RTX 4090, Windows 11, and Resizable BAR was enabled.
For testing, we normally include a lot more software benchmarks than what you’re about to see.
So the focus is going to be on gaming performance as this is where the X3D part should shine.
The results you’re seeing here are with theCorsair iCUE H150i Elite LCD XTinstalled.
With just CCD1 enabled (i.e.
Here, for example, it’s 11% slower and 3% slower than the standard 7950X.
So this looks a lot better.
With the second CCD disabled, we’re seeing an almost 80% increase in performance for the 7950X3D.
For testing CPU performance in Hogwarts Legacy, we used the Hogsmeade section of the game.
Spider-Man Remastered appears to hit a performance wall at around 140 fps.
This means the 7800X3D could be up to 20% faster than the 7700X in this game.
The 3D V-Cache is also providing around a 20% boost over the standard 7950X.
However, it was the massive 18% increase in 1% lows that stands out the most here.
This meant the 13900KS using 7200 memory was 5% faster than the 7950X.
This also allowed the 7950X3D to match the Core i9 processors.
This was enough to see AMD overtake Intel’s 13900KS, albeit by just a 6% margin.
The 7800X3D should be slightly faster again, but overall not much in it.
DecentIntel Z790 boardslook to start around $230, whileAMD X670 boardsare closer to $280.
