Ryzen 9 7900X3D vs i9-13900K, which is healthier?
Up to date: Feb 28, 2023 10:27 am
The Ryzen 9 7900X3D is lastly out, and issues are trying good for AMD’s long-awaited X3D CPU release. On this article, we’re evaluating the Ryzen 9 7900X3D with one in every of Intel’s high processors, the Core i9-13900K. That is Ryzen 9 7900X3D vs i9-13900K.
Now learn: Is Ryzen 7000X3D worth it
Ryzen 9 7900X3D vs i9-13900K: CPU specs
Earlier than we get into all the main points, let’s briefly take a look at the official specs for each processors so we all know what we’re working with.
AMD Ryzen 9 7900X3D
- Core rely: 12 (Multithreading enabled)
- Thread rely: 24
- Clock pace: 4.4GHz
- Increase clock pace: 5.6GHz
- L2 cache: 12MB
- L3 cache: 128 MB
- TDP: 120 watts
- iGPU: Radeon Graphics
- Socket: AM5
Intel Core i9-13900K
- P-cores: 8 (Hyperthreading enabled)
- E-cores: 16
- Thread rely: 32
- P.core clock pace: 3.0 / 5.8 GHz
- E.core clock pace: 2.2 / 4.3 GHz
- L2 cache: 32MB
- L3 cache: 36MB

- Socket: LGA1700
Ryzen 9 7900X3D and Intel Core i9-13900K in contrast
Let’s get the apparent variations out of the best way first. The Ryzen 9 7900X3D is a 12-core, 24-thread processor constructed on the Zen 4 structure.
The 13900K, however, options Intel’s hybrid core structure and packs two completely different core sorts – one designed for efficiency and the opposite for energy effectivity.
We see that the 13900K has the sting in uncooked clock pace, core rely, and thread rely. The one division the place the 7900X3D is main is the L3 cache; the brand new Ryzen processor contains a large 128MB cache dimension.
The 13900K has a wholesome 36MB of cache in its personal proper. However after all, that pales compared to the Ryzen’s 128MB cache.
Gaming efficiency
Each processors supply highly effective gaming efficiency, however the 7900X3D takes the sting right here because of its V-cache enhancement.
The 13900K does lead barely in singlethreaded efficiency, which is one thing we’ve identified to be the first dictator of gaming efficiency for a very long time.
Nevertheless, L3 cache dimension has turn out to be more and more essential currently as effectively. And, as we see with this comparability, the V-cache enhanced R9 7900X3D is ready to constantly supply extra frames in-game than the 13900K, regardless of having a decrease most clock pace.
And the clock pace distinction between the 2 processors is bigger than it might appear initially. Whereas the 13900K cores can increase all the best way as much as a 5.8GHz clock pace throughout gaming, the 7900X3D’s cores barely high 5GHz.
That’s as a result of all game-related processing on the brand new Ryzen processor is carried out on the primary 8-core CCD geared up with Vcache.
Sadly, V-cache may be very temperature delicate, so the increase clock for cores on this CCD needed to be lowered for stability.
The 5.6GHz max clock pace listed within the specs can solely be achieved by the 4 cores housed by the opposite CCD, which aren’t energetic throughout gaming however do pitch in to assist out in heavy multicore workloads.
This simply goes to point out you the way a lot of a distinction V cache makes – the 7900X3D runs at a a lot decrease clock pace than the 13900K whereas gaming however can nonetheless ship extra frames.
Workstation productiveness
For workstation productiveness, the 13900K is the clear winner. And to be truthful, you’ll anticipate it to be. That’s as a result of the 13900K has a outstanding 24 cores and 32 threads. By comparability, the R9 7900X3D has 12 cores and 24 threads.
Not solely does the 13900K have extra cores and threads, however every of those threads can also be working at a better clock pace than the 7900X3D’s when underneath full utilization. So the distinction is fairly clear-cut on this case.
The additional V cache doesn’t actually assist out the Ryzen processor since typical productiveness workloads don’t profit from it to a outstanding diploma.
Energy utilization and thermals
The Ryzen 9 7900X3D has a reasonable 120-watt TDP. That’s first rate, contemplating the efficiency supplied. The 13900K can eat upwards of twice as a lot energy, with a 253-watt max TDP.
The 7900X3D is the extra energy environment friendly of the 2 processors. As a result of each processors eat a good quantity of energy within the first place, the vitality financial savings supplied by the 7900X3D can add up over time.
Ultimate phrases
The distinction between the 2 processors is fairly clear. The R9 7900X3D is the higher gaming processor, whereas the 13900K affords extra multithreaded efficiency, making it the higher workstation processor for duties like video modifying, rendering, and media manufacturing.
