Ryzen 9 7900X3D vs i9-12900K, which is best?
Up to date: Feb 28, 2023 10:51 am
The long-awaited Ryzen 9 7900X3D has lastly hit the market. The processor is a 3D V-cache enhanced variant of the usual R9 7900X, and the additional cache yields some spectacular efficiency positive aspects. On this article, we’re placing it up in opposition to the final Core i9 from Intel. That is Ryzen 9 7900X3D vs i9-12900K.
Now learn: Is Ryzen 7000X3D worth it
Ryzen 7 7900X3D vs i9-12900K: CPU specs
Let’s first go over the official specs for each processors.
Ryzen 9 7900X3D
- Core depend: 12 (Multithreading enabled)
- Thread depend: 24
- Core clock: 4.4GHz
- Increase clock: 5.6GHz
- L2 cache: 12MB
- L3 cache: 128 MB
- TDP: 120 watts
- iGPU: Radeon Graphics
- Socket: AM5
The 128MB of L3 cache is a document quantity, tied with the 7950X3D for probably the most L3 cache on a desktop processor. It’s fascinating to notice that the additional V-cache is on the market to solely one of many two CCD chiplets that make up the Ryzen 9 7900X3D CPU die.
Intel Core i9-12900K
- P-cores: 8 (Hyperthreading enabled)
- E-cores: 8
- Thread depend: 24
- P-core clock velocity: 3.2 / 5.2 (GHz)
- E-core clock velocity: 2.4 / 3.9 (GHz)
- L2 cache: 14MB
- L3 cache: 30MB
- Base TDP: 125W
- Max TDP: 241W
- iGPU: UHD770
- Socket: LGA1700
The 12900K was Intel’s early Alder Lake flagship. It’s now outclassed by among the newer choices however positively stays a high-end possibility.
Ryzen 7 7900X3D and i9-12900K in contrast
Each processors have considerably comparable specs, typically talking. They’re each 24-threaded processors with max clock speeds above 5GHz.
The 12900K has extra bodily cores, however half of those cores are smaller effectivity cores.
Probably the most fascinating distinction between the 2 processors is, after all, the a lot greater L3 cache within the 7900X3D.
Gaming efficiency
Gaming includes a variety of randomnesses (your laptop can’t actually inform what you’re going to do subsequent), so the CPU cores profit from having the ability to maintain extra info nearer to them within the L3 cache.
In additional easy phrases, the additional L3 cache sported by the 7900X3D delivers vital efficiency positive aspects in gaming.
You’ll have seen that the 7900X3D additionally has the next most clock velocity (5.6GHz), however apparently, that doesn’t fairly come into play right here.
Video games run solely on the primary 8-core CCD chiplet that has the additional V-cache. This V-cache-enhanced CCD has a decrease most clock velocity of simply above 5GHz, which is just about equal to the 12900K’s 5.2GHz clock.
The V-cache enhancement alone is sufficient to make loads of distinction, although. After all, video games fluctuate of their capacity to make the most of the extra cache, however, typically talking, you possibly can count on to see the 7900X3D give you wherever from 10 to 30% extra FPS in mainstream titles.
That’s a outstanding distinction, particularly since we’re evaluating processors within the high-end territory as a result of video games nearly all the time find yourself bottlenecked by the GPU when ran on processors of this grade.
Workstation productiveness
For basic productiveness, the 7900X3D takes the cake. Whereas its 2nd, 4-core CCD doesn’t come into play throughout gaming, it really works totally together with the first 8-core V-cache enhanced CCD when tackling workstation-like CPU-intensive workloads comparable to rendering, design, video enhancing, and manufacturing.
You get to see the whole 5.6GHz single-threaded efficiency and top-notch 12-core, 24-thread multithreaded efficiency promised by the 7900X3D in multicore workloads.
The distinction right here isn’t big, although. The 12900K continues to be a terrific workstation processor, solely barely worse than the 7900X3D.
The 7900X3D’s lead on this class may be attributed to its greater most clock velocity, not the additional cache. V-cache doesn’t actually profit workstation-based workloads noticeably, sadly.
Energy consumption and thermals
Whereas the 7900X3D has a reasonable 120-watt TDP, the 12900K can devour nearly 250 watts of energy beneath full load, which is almost twice as a lot. That additionally means the 12900K generates much more warmth and desires a stronger cooling resolution than the 7900X3D.
This can be a issue you need to consider as a result of whereas the 7900X3D can technically be air-cooled with a good air cooler, the 12900K requires you to have a costlier AIO liquid cooler.
You may as well get by utilizing a barely weaker PSU for the 7900X3D, though selecting an appropriate PSU normally has extra to do along with your GPU’s energy utilization.
Remaining phrase
For gaming, the 7900X3D is unquestionably the higher of the 2.
The 8-core CCD module designated for gaming runs at an equivalent clock velocity to the 12900K (5.2GHz), which means single-thread efficiency throughout gaming is about equal.
Nevertheless, the 7900X3D has a a lot greater 128MB L3 cache in comparison with the Core i9’s 30MB L3 cache. The additional cache permits the 7900X3D to ship extra frames within the recreation, even when paired up with comparatively weaker GPUs.
For workstation productiveness, the hole in efficiency is way smaller, with the 7900X3D nonetheless being the winner as a result of its greater most clock velocity on the 2nd 4-core CCD.
