AMD Ryzen 7 5800X3D Review

AMD Ryzen 7 5800X3D Review

summary

Ryzen 7 5800X3D is AMD’s bid to claim the title of “fastest gaming processor”. This works in some games, but on average Intel’s faster Alder Lake processors remain somewhat faster in our game selection. However, AMD’s approach of vertically stacking the additional cache is more creative and elegant than increasing clock speeds as we’ve seen Intel do with the 12900KS before. So the 5800X3D is incredibly efficient while gaming. We’ll reward the 5800X3D with an innovation award for this, but due to the variable performance in other software and the high price tag, it will still be an attractive purchase for a few people.

A week after Intel boosted its lead with Core i9 12900KSAMD attacks the title of “fastest gaming processor”. Coincidence doesn’t exist, does it? However, AMD’s approach seems more interesting. Where Intel has simply increased clock speeds, AMD is for the first time implementing 3D V-Cache, short as an extension of its existing L3 cache, in a consumer processor. we have the AMD Ryzen 7 5800X3D It has been extensively tested.

about a year ago was standing Lisa Su on the platform with its first chip with 3D V-Cache, vertically stacked L3 additional cache. Then it kept a prototype based on the Ryzen 9 chip up in the air, a two-die processor, but the processor that’s now on the market is based on the octacore-5800X. Since each account has a shared L3 cache, only half of the cache is added as with this prototype.

Let’s take a look at the specifications first. As the name suggests, the Ryzen 7 5800X3D is very similar to the regular 5800X. For example, it has the same number of cores and the same tdp 105W. Remarkably, clock speeds are actually lower: single-core boost is 200MHz lower and you even lose 400MHz at base speed. On the one hand, this is necessary to allow the additional power consumption of the 3D V-Cache to match the same TDP, but on the other hand, the innovative production method also seems to throw a wrench in the works to the point that measures clock speed with voltage. We’ll go into more detail about this on the next page.

The Ryzen 7 5800X3D has the same suggested retail price as the 5800X when it came out, at $449. Meanwhile, not only did the euro fall against the dollar, but the 5800X also fell sharply. In practice, at the time of submission there is an additional cost of approximately 150 euros for the model with 3D V-Cache, which is a significant amount.
