About this deal

The Riftbreaker is another game where Zen 4 processors aren't particularly impressive. The 7800X3D manages 225 fps on average, making the 13700K 2% faster which means performance between these two parts is basically identical, but the 13900K is 8% faster. Even with the fix in Horizon Zero Dawn, the 7800X3D is still faster than the 13900K, delivering 6% more performance in this game. Not a huge difference, but previous GeForce drivers handed AMD a significant advantage in this game. The 7800X3D is also just 7% faster than the 7700X, so 3D V-Cache isn't helping much here. The 13700K, on the other hand, was 44% faster, but it also consumed 89% more power, and that's total system power. In terms of efficiency, the 7950X3D is pretty amazing and the 7800X3D is also great for the level of performance it delivers. Gaming Benchmarks

JamesJones44 said:For gaming only the 7800x3d is the best choice. That's why I was a little surprised the came out with a 7900 and 7950 variant.I can see those other variants as people who game when they aren't working but still need a boat load of cores for their work. The most amazing thing about the gaming performance of the Ryzen 7 7800X3D, honestly, is its efficiency. All of the scores I got from my testing never pushed more than 80W of power through the chip, and at less than 80 degrees Celsius, you won't need a beast of a cooling solution for this processor. Outside of what the spec sheet says, the Ryzen 7 7800X3D is notable for using a single-core complex (CCX). The Ryzen 9 7950X3D and Ryzen 9 7900X3D both used a dual CCX design, forcing AMD to focus the cache on a single CCX. The Ryzen 7 7800X3D doesn’t have that problem, which allows for faster transfers. Ultimately, that translates into higher gaming performance in some titles, which I’ll dig into later. Test configurations Jacob Roach / Digital Trends Still, there are some things we can infer just from the little information we have currently. At CES 2023 AMD did provide an initial February launch window, and also availability of the specs for the three chips: No real surprise here. For gaming only the 7800x3d is the best choice. That's why I was a little surprised the came out with a 7900 and 7950 variant.AMD reworked the CCX on the Ryzen 7 7800X3D somewhat to improve its energy efficiency compared with other Ryzen 7000-series processors that don’t have the 3D V-Cache. This was necessary to help accommodate the added heat and power demands of the 3D V-Cache, and it results in the Ryzen 7 7800X3D being one of the more energy-efficient options we’ve tested. Even though we did run into a snag in our testing due to a driver anomaly that we reported to AMD, the Ryzen 7 7800X3D should benefit from the simplicity of a single compute chiplet design. ( Update 4/16/2023: These chips are now at retail for roughly two weeks, but we haven't heard of any reports of this issue, which is a positive sign.) 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 Performance For this review we've had to update all of our already very fresh data. This is because Nvidia recently changed the way their GeForce drivers behave by disabling Resizable BAR in games such as Horizon Zero Dawn and we believe Spider Man-Remastered as well, resulting in performance gains in those games. There were also a few smaller performance changes so we simply decided to re-test everything, including AM4 and AM5 processors.

You can also make your own pricing adjustments, the Ryzen 7700, for example, is 5% slower than the 7700X, so reduce the performance shown here from 199 fps to about 190 fps and then recalculate with your updated pricing. The 7800X3D is 18% faster than the 13900K, 21% faster than the 5800X3D, 25% faster than the 13700K and 38% faster than the 7700X.A processor that has impressive performance might fit well in a high-end work system, but be an unaffordable option for a home PC. A relatively low-performance chip might appear inadequate at first but be an ideal solution in a small form-factor PC where cooling and power limitations prevent power-hungrier chips from being used. All tests were performed inside of Windows 11 with the latest Windows updates installed. An Nvidia GeForce RTX 3080 was also used for all tests except for those focused on integrated graphics performance. CPU Tests The Ryzen 7 7800X3D is a gaming-focused processor, and there’s no contest in that regard. It’s the fastest gaming CPU you can buy, matching and sometimes even outperforming the more expensive Ryzen 9 7950X3D. You lose a lot in productivity performance, but for gamers, the Ryzen 7 7800X3D is still plenty fast. The rest of the test results were mixed, with the Ryzen 7 7800X3D unable to secure any more clear wins. Performance in the rest of these tests were all close together, which does show that, with a card like the Nvidia GeForce RTX 3080, at least with this game subset, you won’t see much in the way of a performance benefit from the Ryzen 7 7800X3D. You will likely need, as AMD advised us, a top-tier card like an RTX 4080 or RTX 4090 to see the 7800X3D pull away. But when you consider that 0.44%—that's less than half of one percent!—of PC gamers are using a GeForce RTX 4080 or 4090 per March 2023's Steam Hardware Survey these days, that's a niche within a niche's niche.
