After a rather revealing leak just hours before the official show, AMD has unveiled its first CPU using the 3D V-Cache design at CES 2022. Ryzen 7 5800X3D will debut the company’s 3D V-Cache tech this spring and according to the numbers presented at the showing, it can take on Intel’s best and beat it by a healthy margin.
For the uninitiated, 3D V-Cache is a chip-stacking technology AMD showed off at Computex last year. In simple words, it adds more cache on top of a core complex, resulting in improved latency, and thus, better performance. AMD developed this solution in conjunction with TSMC so the extra cache is carried on a chiplet based on TSMC’s 7nm process that is optimized for further cache density.
As the name suggests, the 5800X3D is essentially just a normal Ryzen 7 5800X but with a lot more cache. In fact, the clock speeds are actually lower here, perhaps to accommodate for the extra wattage required by the cache chiplet. Whereas the original 5800X had a base clock of 3.8GHz and could boost up to 4.7GHz, the 3D V-Cache based Ryzen 7 5800X3D has a base clock of only 3.4Ghz and a boost clock of 4.5Ghz.
Apart from that, it carries the same 105W TDP and, of course, the same core configuration at 8 cores and 16 threads. Those cores are all Zen3 based since this is a 5800X which also makes it technically fall under Vermeer. Now, for the real kicker. The 5800X3D has a 96MB L3 cache (32+64) as compared to the 32MB cache found on the standard 5800X. That’s a whole 64MB more, putting it above even the Ryzen 9 5950X in terms of cache.
It’s important to note that since the 5800X3D is a Zen3 CPU (technically Zen3D because of the 3D V-Cache but you get the point) it is compatible with the AM4 socket. So, existing B450, B550, X470 and X570 boards should work with the processor and you will be able to overclock it similarly to the standard 5800X. With AM5 and Zen4 being right around the corner, this will be the last processor we’ll see on the AM4 socket.
And apparently that extra bit of cache is all the processor needs to trump both Intel and AMD’s own flagships in gaming. The 5800X3D is, on average, 15% faster than the Ryzen 9 5900X in 1080p gaming performance. Same goes for the Intel Alder Lake Core i9-12900K. Though, the gains versus the Alder Lake processor are less drastic and both CPUs are pretty much neck-in-neck.
AMD showed performance across a number of titles using an RTX 3080 as the graphic median of choice. Against the 12900K, AMD didn’t give us a percentage number, rather a simple quote saying “World’s Fastest Gaming Processor“. The benchmarks attached below tell us that there is a 0.98x to 1.2x increase in frame count for the 5800X3D versus the Core i9. It’s clearly apparent that the 5800X3D beats the i9 more often in recent titles than older ones.
We didn’t get any synthetic benchmarks giving us no productivity numbers to compare. Though that is probably a sign that AMD want to solely target gamers with this product and that the biggest gains here are, in fact, in gaming. According to Dr. Lisa Su, the Ryzen 7 5800X3D “once again makes Ryzen the fastest gaming CPU in the world.”
As of now, there’s no word on pricing but obviously expect it to be higher than the standard 5800X and somewhere around the Ryzen 9 5900X. The chip will be available in Spring of 2022 with no concrete release date in sight. It’s likely that AMD will show us more of the 5800X3D at Computex where we’ll also get a release date to look forward to.
