AMD Ryzen 9 7900X3D: One-minute evaluation
The AMD Ryzen 9 7900X3D is the center little one of the present 3D V-Cache processors from Workforce Crimson alongside the 7800X3D and the 7950X3D. It launched alongside the remainder of the road again in February of this yr and gives heightened gaming efficiency, however comes at a worth.
Indisputably, it is without doubt one of the greatest processors for gaming in the marketplace. However at the same time as avid gamers are going to have the ability to get essentially the most out of this chip, it is productiveness efficiency is not too dangerous both.
Armed with a considerably decrease TDP than the remainder of the present AMD Zen 4 lineup, the AMD Ryzen 9 7900X3D packs in 12 cores and 24 threads on a 120W TDP with a base clock velocity of 4.4 GHz out of the field, and that is truthfully the core attraction of this chip.
It is extra energy environment friendly and gives higher uncooked gaming efficiency than its non-3D counterpart, however the addition of AMD’s 3D V-cache means it could possibly maintain up with far pricier processors as effectively.
It must be said that general, you are falling into one in all two camps with the AMD Ryzen 9 7900X3D, as it’s spectacular for gaming, however will not essentially set the world on fireplace with the creativity or productiveness facet of issues on the larger finish of the spectrum.
The uncooked gaming efficiency at its $599 / £479.99 / AU$859.99 worth level is first rate, however chances are high for those who’re spending this a lot on a CPU purely for gaming, you might argue that an additional $100 / £130 / AU$279 for the top-end 7950X3D may very well be a greater wager as a substitute.
AMD Ryzen 9 7900X3D: Worth and availability
- Comparable worth to the Intel Core i9-13900K
- $50 / £50 / AU$64 greater than base 7900X
The AMD Ryzen 9 7900X3D was launched on February 28, 2023, and presently retails for $599 / £479.99 / AU$859.99.
That is round $100 / £130 / AU$279 lower than the flagship AMD Ryzen 9 7950X3D which options 16 cores and 32 threads. As some extent of comparability, this AMD processor is available in just a little cheaper than the Intel Core i9-13900K within the UK and Australia, the place it presently sells at £699 / AU$929, and is simply $10 dearer within the US.
That is just one facet of the story, although. That is as a result of the AMD Ryzen 9 7900X3D requires an improve to the most recent AM5 socket, which implies a wholly new motherboard in addition to the unique use of DDR5 RAM, and the most effective DDR5 RAM is not low cost (even when it has come down in worth).
Primarily, you will be constructing a wholly new system across the chip as there isn’t any extra backward compatibility with AM4 as we noticed with the 2 earlier Ryzen processor generations (although the most effective CPU coolers for AM4 processors will nonetheless work with the brand new AMD chips).
That is owing to AMD’s transition from a PGA to LGA socket, which simply signifies that the processor now not has pins the best way earlier generations did, very like with the most effective Intel processors.
AMD Ryzen 9 7900X3D: Chipset & options
- Improved energy effectivity
- Zen 4 3D V-cache for underneath $600 / £500 / AU$900
The AMD Ryzen 9 7900X3D options lots of the identical broad strokes as its non-3D variant. You are getting the identical 12 cores and 24 threads on the AM5 socket with a complete enhance clock of as much as 5.6GHz. The core distinction right here, nonetheless, is the 3D V-Cache which doubles the inventory model’s 64MB L3 Cache for a complete of 128MB.
The upper the L3 cache is, the higher gaming or intensive processing workloads can carry out, that is as a result of it is the most important stage of cache accessible on a processor.
Added cache apart, the AMD Ryzen 9 7900X3D can be considerably extra power-efficient than any present non-3D Zen 4 processors accessible, because it clocks in with a Thermal Design Energy (TDP) of 120W, which is far decrease than the considerably larger 170W of its inventory variant.
Whereas the next TDP normally pertains to larger efficiency, the inclusion of the added 3D V-cache signifies that the processor can entry a bigger pool of superfast cache reminiscence, which is much more helpful when gaming than simply throwing uncooked energy on the downside. With its personal devoted additional cache, there are fewer fetch operations to the PC’s fundamental reminiscence, so the chip runs extra effectively, and probably cooler underneath load.
That is mirrored when contrasted towards the AMD Ryzen 9 7900X’s core clock velocity of 4.7 GHz to the 3D variant’s 4.4 GHz. It is just a little slower out of the field regardless of the overclocking potential being the identical, nonetheless, the AMD Ryzen 9 7900X3D continues to be far quicker than any of the present Alder Lake or Raptor Lake processors when it comes to the uncooked velocity.
In the end, the diminished reminiscence latency signifies that you are getting a chip that runs cooler, attracts much less energy, and performs higher due to the addition of the second era of AMD’s V-cache.
- Design & options rating: 4 / 5
AMD Ryzen 9 7900X3D: Efficiency
You will not be shocked to listen to that the AMD Ryzen 9 7900X3D is without doubt one of the most succesful CPUs for gaming that I’ve ever used, holding its personal towards the flagship 7950X and the Intel Core i9-13900K.
That is evidenced by a few of the most spectacular artificial scores thus far in industry-standard packages corresponding to GeekBench 6, PCMark10, and Cinebench R23, amongst others, and you’ll see how the Ryzen 9 7900X3D compares to competing high-end processors beneath.
| Take a look at | Ryzen 9 7900X3D | Ryzen 9 7950X3D | Core i9-13900K |

| PCMark10 | 8,385 | 9,936 | 10,157 |
The place the AMD Ryzen 9 7900X3D falls behind the Intel Core i9-13900K and the 7950X3D when it comes to the productiveness benchmarks, the hole is significantly closed with the uncooked gaming efficiency. Turning to the gaming benchmarks, this chip’s 3D V-cache makes all of the distinction in demanding titles corresponding to F1 2022, Returnaland Complete Conflict: Warhammer 3.
| Recreation title | 7900X3D |
|---|---|
| Complete Conflict: Warhammer 3 | 417 |
| Returnal | 171 |
| F1 2022 | 415 |
As with our different CPU opinions, the video games examined within the AMD Ryzen 9 7900X3D evaluation are examined at 1080p on the lowest graphics settings to be able to isolate the processor’s contribution to gaming efficiency. Beneath, you may see how this chipset compares to the most effective AMD processor and greatest Intel processor respectively.
| Recreation title | Ryzen 9 7900X3D | Ryzen 9 7950X3D | Core i9-13900K |
|---|---|---|---|
| Complete Conflict: Warhammer 3 | 417 | 464 | 611 |
| Returnal | 171 | 274 | 169 |
| F1 2022 | 415 | 560 | 448 |
In comparison with the dearer chipsets, the AMD Ryzen 9 7900X3D completely holds its personal with the 7950X3D and the 13900K, with the most important hole seen seen with how AMD’s flagship handles Returnal. That is probably on account of the truth that the 7950X3D makes use of a further 4 cores and eight threads, and Complete Conflict sequence has at all times been Intel’s strongest gaming benchmark, which stays the case right here.
Nonetheless, with the Ryzen 9 7900X3D, we’re nonetheless speaking about an absolute powerhouse of a CPU, with framerates effectively above 100fps in demanding video games, and upwards of 400fps in tamer titles. Realistically, you may anticipate this chip to be an absolute behemoth for 1080p, although you will get diminishing returns at 1440p and 4K if you do not have the beefiest video card in your rig that may sustain with the processor.
General, the AMD Ryzen 9 7900X3D is a powerful processor for the cash which is unquestionably geared extra towards gaming than productiveness or creativity duties. If you happen to’re purely taken with enjoying video games then this processor gives sturdy price-to-performance on the $600 / £480 / AU$860 mark, however with the Ryzen 9 7950X3D so shut in worth, lots of patrons on the market are more likely to be torn.
