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 7800X3D is impressive when it comes to power consumption. For example, the 13600K was 11% faster here, but for that extra performance we saw a whopping 52% increase in total system power consumption. If you are on a more limited budget and can't go for one of the more expensive chips, then you're going to have to decide which is more important: gaming, or everything else. If you choose gaming though, you won't be disappointed with the AMD Ryzen 7 7800X3D.
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 Blender Open Data is a core-heavy workload that isn't as efficiently accelerated by Intel E-cores and as a result the 13600K was just 11% faster in this test, though the 13700K mauled the 7800X3D by a 44% margin.
When it comes to productivity though, the 13900K is simply in a different league, as is the 13700K. 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
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. In this game, Intel's Core i9-13900K pushes total system usage just 16% higher than the 7800X3D and while that's a 73w increase in power draw, it's by no means the worst result we've seen. 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 AMD Ryzen 9 7950X3D and Intel Core i9-13900K are undoubtedly two of the best processors you can buy, but they aren't equal. We threw both of the CPUs on the test bench to answer the age-old question: is AMD or Intel better? Both are extremely power hungry for all core productivity workloads though, and need to be power limited, and at that point you are better served by the 7950X or 7950X3D which typically deliver a similar level of performance to that of an unlimited i7 or i9 while reducing total system usage by half, which is a staggering difference.
AMD's chipset driver manages which cores are best suited for specific tasks so games that benefit from V-Cache, for instance, get put on V-Cache cores while other apps would get thrown onto the full frequency cores. 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. 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. Similarly, the Ryzen 9 7950X3D squeezed out a win in Hitman 3,but the cheaper eight-core part was within a few frames. This game is a great showcase of Zen 4 and 3D V-Cache at work, with the Ryzen 7 7800X3D outpacing the previous generation by a whopping 26%. 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.
Unfortunately, this does not apply to the 7800X3D, which only has eight V-Cache-accessing cores. This translates into a lower 4.20GHz base frequency, compared to the 4.5GHz of both the 7950X3D and 7700X, and a boost frequncy of just 5.0GHz, compared to 5.7GHz and 5.4GHz for the 7950X3D and 7700X, respectively. This is also slower than the top speed of the Core i7-13700K, which boosts up to 5.40GHz from 3.40GHz base frequency. You can read the deep-dive details on AMD's thread-targeting implementation here, but the key takeaway is that it requires four different components to work together to alter the thread assignments into the cores automatically. AMD released the Ryzen 7 5800X3D around the time when its Ryzen 5000 Zen 3 series found itself bested by Intel's 12th Gen Core Alder Lake. The 5800X3D beat the fastest Core i9-12900K in gaming, forcing Intel to scamper for Special Edition chips with limited availability, such as the i9-12900KS, that level up to the 5800X3D, but at enormous power needed to maintain a 5.00 GHz all-core boost for the processor's eight P-cores. Fast forward to 2023 and we see the 7800X3D wanting to eat Intel's lunch in the high-end gaming CPU market once again, with its sights set on the Core i9-13900K. 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. These are the systems I used to test desktop CPU performance for both AMD and Intel chips in this review:
Then when running the single core test, we saw a sustained frequency of 5 GHz, so just a 200 MHz increase over the all core. The peak operating temperature also dropped to 66c. Benchmarks That said, if this data was vital to the review we would have included it, but realistically most people considering the 7800X3D are after a more no-compromise type gaming experience and therefore will likely be considering high-end CPUs offering maximum performance... Along with updating the RTX 4090 with the latest GeForce drivers, we've also updated all the motherboards BIOS revisions and we've moved the LGA1700 test system over to the Gigabyte Z790 Aorus Elite AX using DDR5-7200 CL34 memory. As for the AM5 test system, that's still using the Gigabyte X670E Aorus Master with DDR5-6000 CL30 memory, as that's the fastest memory speed that will work with all Zen 4 processors. Operating Behavior That’s not to say the Ryzen 7 7800X3D is slow because it’s not. It still shows massive gains over the previous generation in the web-based Jetstream benchmark, and it managed to match the Ryzen 9 7950X in Photoshop (though, Intel still claims the lead in Adobe benchmarks). Gaming performance Jacob Roach / Digital Trends 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.In 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 Ryzen 7 7800X3D has impressed us with its performance, but we're not blown away by the FPS figures. What has blown us away is the power efficiency, but how much gamers care about that is hard to say. Shopping Shortcuts: JamesJones44 said:For gaming only the 7800x3d is the best choice.
