Move Aside 7950X3D, AMD Ryzen 7800X3D Is New Gaming CPU King


7950X3D vs 7800X3D vs 13900K: The reviews for the AMD Ryzen 7 7800X3D are out. Almost all of them show it beating other offerings from AMD and Intel while costing far cheaper.

When AMD announced Ryzen 7000 series, everyone, especially gamers, were waiting for one thing. Whether AMD is going to release a 3D V-Cache based CPU in it too. Many wanted AMD to release a Ryzen 7000 series version of massively popular AMD Ryzen 7 5800X3D.

To everyone’s surprise, AMD announced not one, but three processors with 3D V-Cache. AMD Ryzen 9 7950X3D, 7900X3D and Ryzen 7 7800X3D. This took the amount of X3D chips that AMD offered to 4 in total so far.

What 3D V-Cache does is it installs an additional 64 MB of cache on top of a pre-existing 32 MB cache on a single CPU chip. This gives the extra cache based CPUs a tremendous speed boost in workloads which benefit from it. Which is mostly limited to gaming.

When AMD released Ryzen 9 7950X3D and Ryzen 9 7900X3D, many wondered about two things. First, how will AMD Ryzen 7 7800X3D perform. Second, how will AMD install the extra cache on the top two CPUs.

The reason for the above question is simple. While AMD Ryzen 7 7800X3D comes with a single 8-core chiplet. AMD Ryzen 9 7950X3D and 7900X3D come with two 8-core and 6-core chiplet respectively. So What AMD did was to keep one chiplet without extra cache and boost its clock speed. The other chiplet, however, came with extra cache like mentioned above. The reason is simple, games don’t benefit much for above 8 cores.

So when Ryzen 7 7800X3D was announced. Everyone got excited. Looks like the reviews are exciting too.

Tom’s Hardware did a review for the AMD Ryzen 7 7800X3D.

First of all. They mentioned how the chipset driver AMD had released for Ryzen 9 7950X3D and 7900X3D created issues with Ryzen 7 7800X3D. This is because it was wrongly parking CPU cores in the 7800X3D during gaming (page 3 of the review), something which was meant for parking non-3D Cache chiplet cores in Ryzen 9 7950X3D and 7900X3D processors. The only way to fix this was to re-install the OS completely from the start.

Talking about the review. AMD Ryzen 7 7800X3D performs mediocre or poorly in productivity software due to it being a lower clocked CPU. However, what it excels is in gaming. In gaming benchmarks, AMD Ryzen 7 7800X3D equals or beats 7950X3D by a small margin at 1080p. Not only that, it’s 11% faster than the Intel’s flagship offering, the Intel Core i9-13900K at 1080p.

What is interesting is that the review finds AMD Ryzen 7 7800X3D to be significantly slower than Ryzen 9 7950X3D and Intel Core i9-13900K in 99th percentile FPS at 1080p, which is important for smoothness of gameplay. The reviewer blame a single game for the anomaly. However, that is fixed in the 1440p where Ryzen 7 7800X3D is back at top in 99th percentile FPS. The average FPS is a non-issue though, Ryzen 7 7800X3D is absolutely on top.

In terms of power usage (page 2), AMD Ryzen 7 7800X3D is extremely efficient. At max, it uses 82W at stock. Whereas Ryzen 9 7950X3D uses 143W and Intel Core i9-13900K uses a huge 280W for the same test.

igor’sLAB too did a review of AMD Ryzen 7 7800X3D.

In performance in 1080p (page 4), AMD Ryzen 9 7950X3D beats AMD Ryzen 7 7800X3D in average FPS tests by a very small and insignificant margin. Which they blame on slightly lower clock rates. However, that changes in 1440p tests where 7800X3D is back on top.

Here too in 1% low FPS, the Ryzen 9 7800X3D lags behind others a little at 1080p and 4K, but improves on 1440p.

Either way, at 1080p, AMD Ryzen 9 7800X3D is 9% faster than Intel Core i9-13900K, 17% faster than AMD Ryzen 5800X3D and 26% faster than the $50 cheaper Ryzen 7 7700X.

In terms of power usage (page 11), here too, AMD Ryzen 9 7800X3D is extremely efficient. At max using 88W in complex applications whereas Ryzen 9 7950X3D uses 144W and Intel Core i9-13900K uses a huge 280W for the same test. They however checked power usage in gaming too. In gaming, AMD Ryzen 9 7800X3D averaged at 40W, while Intel Core i9-13900K used 75W.

TechPowerUp was another one with the review for the AMD Ryzen 7 7800X3D.

They too mentioned the problem they had with AMD chipset drivers and core parking (page 28) and they too had to reinstall the OS to get rid of the issue, as recommended by the AMD’s guide.

In terms of gaming performance. Here too, the AMD Ryzen 9 7800X3D shines a lot. At 1080p, it’s almost 6% faster than both AMD Ryzen 9 7950X3D and Intel Core i9-13900K. At 1440p and 4K too it’s ahead than others.

In minimum FPS tests (page 22), AMD Ryzen 9 7800X3D leads ahead at 1080p, while being only slightly slower (1 FPS) than the other two at 4K.

In power efficiency (page 23), the power usage was similar as other reviewers in applications. However, while in gaming where AMD Ryzen 9 7800X3D used just 49W, Intel Core i9-13900K used 143W, almost three times more.

What TechPowerUp did which many other reviews didn’t. They tested the temps of AMD Ryzen 9 7800X3D. At stock, it didn’t go above 82C in complex workload and the gaming temps were significantly lesser than that.

TechSpot posted their review for AMD Ryzen 9 7800X3D only slightly later than others.

In performance at 1080p, it scores the same as AMD Ryzen 9 7950X3D. It’s also 3% faster than Intel Core i9-13900K.

In total PC power usage, the 7800X3D PC uses 207W. Whereas, AMD Ryzen 9 7950X3D uses 279W and Intel Core i9-13900K uses a huge 493W for the same. This information is important for those who buy a 1000W or more PSU for their PC.


There are many other reviewers one can check out. Like the detailed written ones from AnandTech. There is one that KitGuru has gotten too. Even famous YouTube reviewers like Gamers Nexus and Hardware Unboxed have posted their reviews on it.

Whatever review one checks, overall they all say the same thing. AMD Ryzen 7800X3D is as fast as or faster than the AMD Ryzen 9 7950X3D. It also beats Intel Core i9-13900K by some small margin. However, what’s the biggest difference is that it’s extremely power efficient than others.

It’s important to mention that a $449 AMD Ryzen 7800X3D is equaling a $699 AMD Ryzen 9 7950X3D and beats a $589 Intel Core i9-13900K.

Talking about the costs. The only issue until recently was the platform as a whole. The AM5 motherboards required for it are expensive. The DDR5 RAM which it requires were expensive too.

However, both the things can be largely sorted now. Higher quality versions of recently released A620 chipset motherboards can be paired with this CPU, though after some checking as some A620 ones only allow 65W CPU, whereas AMD Ryzen 7800X3D is rated for 120W. So it’s important to check the specs. The DDR5 RAM prices too have gotten cheaper considerably recently.

Some people complain about productivity speeds in this CPU. Which is understood if someone uses these things professionally. For those type of users, AMD Ryzen 7950X3D is suggested. However, common gamers are going to benefit massively from the Ryzen 7800X3D. Not to forget, speed difference in common tasks are hardly noticeable.

In all, AMD Ryzen 7800X3D is one of the best and greatest CPUs ever created in the world of computer gaming. Let’s hope Intel too has an answer for it. Maybe they too can consider adding extra cache in their processors.
