Almost a yr after the announcement of AMD’s 3D V-Cache chiplet design, we are able to lastly speak in-depth in regards to the expertise and the processor that’s set to function its cradle, the Ryzen 7 5800X3D. With the implementation of improved built-in reminiscence expertise and claims of higher single-core and general gaming efficiency than its non-3D counterpart and – maybe reasonably boldly – Intel’s personal Core i9-12900K, there’s nothing else to do aside from one factor.
Take this CPU for a spin.
Specs
Design
We’ve talked about AMD’s Zen3 CPU structure for the higher a part of two years at this level, there technically isn’t lots of new floor to interrupt on its lithography, aside from that one apparent addition, the 3D V-Cache chiplet design. On the finish of the day and to reiterate, the 5800X3D is principally AMD’s closing tune and farewell quantity for the Zen3 structure. So, if nothing else, it’s really a good option to ship off the structure and open the best way ahead for the Zen4 structure that’s anticipated to make its debut later this yr.
As for what’s completely different within the 5800X3D, you’re nonetheless acquired the identical 8-cores, 16-threads because the 5800X, however because of the brand new 3D V-Cache design, it has thrice the quantity of L3 Cache, actually. I’m speaking about 96MB of L3 Cache and that is achieved by stacking the extra cache vertically, as a substitute of laterally. If that design methodology sounds acquainted, it’s in all probability as a result of AMD’s took a cue out of its personal e book, when it beat the competitors to the punch with its first Excessive Bandwidth Reminiscence (HBM) design years in the past. The place the chipmaker stacked the chiplets for it on prime of it every, in order to chop down on the response time between every die and its capacitors.
However tripling the L3 Cache for improved efficiency comes with a few trade-offs. As you’ll see within the specs sheet above, the bottom and increase clocks are barely slower than the 5800X, whereas the CPU voltage has additionally been lowered from 1.35V to 1.3V. Additional, not one of the cores will be overclocked; due to the constraints of right now’s manufacturing expertise, AMD has no alternative however to implement a tough lock onto the processor.
The excellent news is that it is a one-off implementation and that this received’t be the case with future Ryzen CPUs.
Testbench
The testbench I’m utilizing to check out the CPU is identical X570 setup that I’ve used since 2019, with the one modifications being primarily beauty. On one other be aware, the 5800X3D would be the first CPU in my record that shall be examined utilizing Home windows 11.

Whereas it isn’t listed right here, the GPU I’m utilizing to run my take a look at is an NVIDIA GeForce RTX 3090 FE. Additionally, I up to date the motherboard’s BIOS to the newest AGESA, as per AMD’s advice to forestall any throttling or efficiency bottlenecks whereas testing the CPU.
Benchmarks
Within the artificial benchmarks, it’s clear that the 5800X3D is neither taking part in catch up nor pulling forward of the non-3D 5800X, and appears evenly balanced within the 3DMark exams. Within the Cinebench R20 take a look at, the processor’s efficiency is clearly affected by the caps on the CPU. Nevertheless, AMD did warn us about these slight efficiency hits with artificial benchmarks.
One of many titles AMD appreciated to point out off throughout its transient presentation operating their chops is Shadow of the Tomb Raider. As we are able to see within the charts, the 5800X3D clearly delivers and pulls forward of Intel’s personal top-of-the-line 12900K in that title, but in addition in a few others, together with Management and Deus Ex: Mankind Divided. For that matter, the 5800X3D can also be leaps and bounds forward of the 5800X and fairly surprisingly, it’s the dominating processor when put up towards AMD’s 5950X.
Temperature And Energy Consumption
There may be, in fact, the topic of warmth era and energy consumption to think about with the 5800X3D, and based mostly on what I’ve seen, the outcomes right here aren’t fairly as stunning as I had imagined. Whereas it appears to attract extra energy than the 5800X whereas idling, its sustained energy consumption when it’s put to work is kind of the identical as its non-3D counterpart. For that matter, it’s the 12900K that’s taking the lead right here, consuming much less energy than the all three AMD on the record.
It’s an analogous story with the 5800X3D’s general temperature too. Whereas it operates just a few levels larger than the remainder of the group, it’s nonetheless inside acceptable parametres.
Conclusion
As I stated close to the start of this assessment, the AMD Ryzen 7 5800X3D may be very clearly the corporate’s swan tune, the final hurrah for all its high-performance endeavours with the Zen3 structure, if you’ll. No matter its barely muted efficiency in comparison with its 3D V-Cache-lacking siblings, it’s nonetheless a succesful workhorse when put to work, and extra so when put to the duty it was so clearly designed and made for: gaming.
And whereas it feels a bit odd that the 5800XD’s cores can’t be overclocked, the ultimate gaming outcomes it may possibly obtain with its vertically stacked L3 Cache greater than makes up for the shortage of the function. So, in the event you’re not totally bothered about not having the ability to push the cores of the 5800X3D to breakneck speeds and also you’re in search of one thing barely extra reasonably priced than the Ryzen 9 5900X, or in the event you’re making a bounce from a 1st or 2nd era Ryzen CPU, then contemplate this in your PC.
The AMD Ryzen 7 5800X3D will go on sale on 20 April and can retail for US$449 (~RM1901). On the time of writing, we nonetheless should not have native pricing.
