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 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
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. 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 As for power consumption, we're going to show total system usage as we feel that's more relevant to someone looking at buying this CPU. These results are heavily influenced by performance, as in how many frames the RTX 4090 is able to pump out, so do keep that in mind. That said, the 7800X3D was 3% faster than the 13900K in this game while using 20% less power, so that's a big deal when it comes to thermal output.The 7800X3D's worst performance against the 13900K was Returnal, where it averaged about 12.5% fewer fps, while still managing an impressive score of 224 fps. Meanwhile, the 7800X3D battled the 13900K to a technical decision in Total War: Warhammer III (552 fps for the 7800X3D to the 13900K's 594 fps), while handily beating the more powerful processor in F1 2022 and Tiny Tina's Wonderland. 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. 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. 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. The Core i9-13900K gains ~5% more performance on average when going from DDR5-6400 to 7200 memory in our testing, so with more affordable memory the 7800X3D would be around 7-8% faster.
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.
Even so, the 7800X3D is 9% faster than the 13900K and remember the Core i9 processor has been paired with DDR5-7200 memory which does help in this bandwidth-sensitive game. Next up we have Shadow of the Tomb Raider and here the 7800X3D was the fastest CPU tested, pumping out an impressive 330 fps, making it 6% faster than the 7950X3D and 13% faster than the 13900K. We're also looking at a rather substantial 27% boost over the 7700X. Simply put, AMD's Ryzen 7 7800X3D fails to fill much of a niche. If you are after a fast processor in terms of pure CPU grunt, you’d be better off with almost any other chip shown in the charts above. Almost all of them are faster, and many of them are cheaper, too. Naturally, this means the Ryzen 7 7800X3D also doesn’t make sense as a budget option. 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. 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.
You can tinker with the performance profile to a degree in the Ryzen Master utility if you need to eek out some extra non-gaming performance, but how effective that will be will take a lot more testing on my part than I have time for in this review. Personally, I wouldn't even want to push it further than where its at, since the prospect of a processor running under 100W paired with a newer GPU running less than 200W has me seeing mini gaming PC builds dancing through my head. We did measure total system power usage for this game and here the 7800X3D configuration consumed slightly more power than the 7700X, a 4% rise, but we saw a 27% increase in performance, so the 3D V-Cache part was significantly more efficient. It also consumed 21% less power than the 13900K, despite delivering 13% more frames, so while the 13900K was quite impressive in terms of performance, power efficiency is just horrible.Having extra cache certainly can improve performance, though. One of the most commonly known things about computers is that more RAM can help your PC work faster, and cache is in many ways no different from RAM. Though both are essential, and having more is often beneficial, having too much of either can be detrimental, or at least accrue no additional benefit. Higher-capacity RAM kits often run at slower speeds, and the overabundance of cache on the Ryzen 7 7800X3D forces it to run at slower speeds, too. Like all AMD Zen 4 chips, though, this one will require you to upgrade to the AM5 platform, so you'll need a new motherboard if you don't already have a Zen 4 Ryzen 7000-series setup. You'll also need new DDR5 RAM, so this could be a more expensive upgrade than just the chip itself. That said, the same is pretty much true about Intel Alder Lake and Raptor Lake, so if you're upgrading from an 11000-series Intel chip or older, you're going to be paying a lot of money to make the upgrade either way. Cyberpunk 2077 has been tested with ray tracing enabled and here the 7800X3D basically matched the 7950X3D while producing similar numbers to the 13900K, though 1% lows are a bit stronger. 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.
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.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. 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).
