Last week, AMD started rolling out the highly anticipated Ryzen 7 5800X3D as their first 3D V-Cache consumer-grade CPU, and they claim to be the “world’s fastest PC gaming processor,” even capable of powering Windows games Beyond the Core i9 12900K/12900KS. AMD didn’t seed this launch, which leads us to expect it to be less good for Linux gaming/not their target market. But after my great success with AMD Milan-X performance on Linux, I was very eager to try out this consumer-grade CPU with 3D stacked L3 cache and ended up buying the 5800X3D. In fact, the Ryzen 7 5800X3D is disappointing in terms of Linux gaming performance, but the 5800X3D is very interesting for a range of other technical workloads, which makes me very excited about future Ryzen CPUs with 3D V-Cache.
The AMD Ryzen 7 5800X3D as a refresher is AMD’s only 3D V-Cache desktop CPU currently. The Ryzen 7 5800X3D is very similar to the existing Ryzen 7 5800X, but swaps the 3.8GHz base clock for a 3.4GHz base clock and has 96MB of L3 cache thanks to the 3D V-Cache, while the 5800X only has 32MB of L3 cache. The Ryzen 7 5800X also has a max boost clock of 4.7GHz, while the 5800X3D is limited to 4.5GHz. Both models have a 105-watt TDP, Zen 3 cores, and other common features besides a large L3 cache, while swapping it for a lower base clock of 400MHz and a lower max turbo clock of 200MHz.
The AMD Ryzen 7 5800X3D will work with existing AM4 motherboards that support the Ryzen 5000 series when using the latest motherboard BIOS version.
I purchased a Ryzen 7 5800X3D to be able to perform these Linux benchmarks, unfortunately didn’t receive any review samples from AMD this time around. I was able to pick up the Ryzen 7 5800X3D for the suggested price of $449, and the Ryzen 7 5800X retails for about $335. However, as of this writing, the Ryzen 7 5800X3D appears to be sold out at all major internet retailers.
I’ve been benchmarking the AMD Ryzen 7 5800X3D under Linux for the past few days and got preliminary data to look at Linux gaming performance, but what’s more exciting is how well AMD Ryzen 3D V-Cache is doing in other areas Performance gets a boost from this large L3 cache. Today’s article only focuses on the performance of the 5800X vs. 5800X3D, as time is limited since getting the 5800X3D, and all comparison CPUs are always re-benchmarked for comment – stay tuned for new Larger comparisons and other follow-up 5800X3D benchmarks in the days and weeks ahead.
The “TLDR” version is that the AMD Ryzen 7 5800X3D is a waste for Linux gamers, but there are actually many other areas that show real promise for the 5800X3D and wider Ryzen CPUs with 3D V-Cache. Since there’s only this one octa-core SKU with 3D V-Cache, it’s fairly narrow, but when being able to find a 16-core 3D V-Cache/better in line with flagship Ryzen does give me an idea of what’s to come Product is very excited model.
