We've been asked by some members of the driving simulator community to change the way we test ACC, moving away from the Medium preset to Epic, so that's what we've done and this has led to some interesting results which verify what some sim racers have been reporting. Hitman 3 doesn't run particularly well on Zen 4 processors, at least relative to Intel Raptor Lake CPUs. The 7800X3D is just 4% faster than the 7700X and that means it's 11% slower than the 13900K and 8% slower than the 13700K. Once again, if you're interested in productivity performance then the 7800X3D isn't going to be for you, unless your workload benefits from having the 3D V-Cache which isn't the case for Blender. System Power Consumption

The 7800X3D basically matches the 7950X3D in the end, making it just 3% faster than the 13900K, and while that's technically a win for AMD, we think it's fair to say overall performance is much the same. The 7800X3D is 18% faster than the 13900K, 21% faster than the 5800X3D, 25% faster than the 13700K and 38% faster than the 7700X.But of course, given performance is basically identical, consuming an additional 73 watts is not a good result for Intel. 12 Game Average (RTX 4090 at 1080p) Next up we have Hogwarts Legacy with ray tracing enabled and here the 7800X3D does quite well, edging out the 13900K by a 3% margin, so performance overall is much the same between these two CPUs. Of course, what matters most is performance across the board, and we’re as keen as you to get some verified benchmarks to consider. As soon as we do, we’ll give you our expert view on this next step in AMD’s Zen 4 journey. We suspect the 7950X3D is using the 3D V-Cache enabled CCD for this workload, which is why the 7800X3D offered a similar level of performance.

This is already an enormous amount of L3 cache to have on a chip, but AMD pushes this to the next level by applying a 64MB 3D V-Cache chip to the Ryzen 7 7800X3D’s CCX. In total, this gives the Ryzen 7 7800X3D a massive 96MB of L3 cache. However, the 3D V-Cache cache might be better referred to as L4 cache, as it is architecturally separate from the CCX’s L3. The 3D V-Cache is also ever so slightly slower, though AMD has said the performance difference here is exceedingly small. Visual performance in general tended to be a bit better on the IGPs on competing Intel chips here as well, so if you are buying a processor and don’t want to buy a graphics card, it’s worth keeping this in mind. Power and Thermal PerformanceIn this review we're testing AMD's new Ryzen 7 7800X3D, which is the company's latest gaming monster based on the 3D Vertical Cache technology. It features an 8-core Zen 4 CCD with high frequencies, and should be able to provide a generational gaming performance uplift, letting AMD surpass even the fastest of Intel's 13th Gen Core Raptor Lake processors at gaming. For the bulk of gamers and e-sports athletes that aren't big on "gaming++" workloads such as streaming, heavy video processing, and live social media; and just need a processor for maxed out AAA gaming at the highest resolutions, with the fastest graphics cards available, the 7800X3D is supposed to be their knight in shining armor. The one area where the Ryzen 7 7800X3D has a hint of success is in the gaming market, but it's walking a thin line there. AMD provided us with data that clearly shows the Ryzen 7 7800X3D can perform better than the Intel Core i9-13900K or the AMD Ryzen 7 7700X when all three are paired with an Nvidia GeForce RTX 4090.
