AMD Ryzen 9 7950X3D Review: AMD Takes Back the Gaming Crown with 3D V-Cache
AMD’s $699 Ryzen 9 7950X3D has a 16-core thread stack that may deal with the heaviest productiveness workloads, whereas being specifically designed for players who need a blast in CPU-limited video games. The brand new chip contains the corporate’s second-generation 3D V-Cache know-how that unlocks 128MB of L3 cache, a mix of sixteen Zen 4 cores and the corporate’s quickest gaming efficiency in the marketplace. In our exams, the 7950X3D topped our listing of the perfect CPUs for gaming, beating Intel’s quickest chip, the 6GHz Core i9-13900KS, by a median of 13% and by as much as 40%+ in some video games.
The 7950X3D makes use of AMD’s newest 3D chip stacking know-how referred to as 3D V-Cache to offer an unimaginable 128MB L3 cache. Just like the Zen 3 Ryzen 7 5800X3D, AMD’s first X3D chip, the additional L3 cache comes due to a 3D stacked SRAM chip on prime of the processor mixed with hybrid coupling, which takes gaming to new heights in lots of video games. AMD additionally has a brand new thread concentrating on method designed to assist the good points apply extra evenly throughout a variety of video games.
The primary-generation 3D V-Cache chip gave AMD a lead over Intel’s rival processors and made it a necessary chip for players, nevertheless it struggled with some productiveness purposes as a consequence of its eight-core restrict and comparatively low enhance frequency. AMD’s new 16-core Ryzen 9 7950X3D, the primary 3D V-Cache chip to make use of two compute chips, boosts productiveness purposes and a better enhance of 5.7GHz, an enormous enchancment over the earlier technology’s 4.5GHz peak. gives the frequency.
Value | Cores / Enamel (P+E) | P-Core Base / Increase Clock (GHz) | Cache (L2/L3) | TDP / PBP / MTP | |
---|---|---|---|---|---|
Ryzen 9 7950X3D | 699 {dollars} | 16 / 32 | 4.2 / 5.7 | 144MB (16+128) | 120W / 162W |
Ryzen 9 7900X3D | $599 | 12 / 24 | 4.4 / 5.6 | 140MB (12+132) | 120W / 162W |
Ryzen 7 7800X3D | $449 | 8 /16 | 4.2 / 5.0 | 104MB (8+96) | 120W / 162W |
Ryzen 7 5800X3D | 348 {dollars} | 8 /16 | 3,4 / 4,5 | 104MB (8+96) | 105W |
Intel’s Raptor Lake lately took the gaming efficiency crown from AMD’s Zen 4 Ryzen 7000 chips, however AMD is now pushing the X3D offensive, which is available in 8-, 12-, and 16-core variants, all from $449 to $699. expanded with three alternating chips. It comes with the corporate’s newest Zen 4 structure etched on the 5nm course of. These chips are present in AM5 motherboards that assist the most recent connectivity applied sciences similar to DDR5 and PCIe 5.0 and deal with one other shortcoming of the primary technology mannequin. AMD additionally unlocked the chip for fundamental overclocking and undervoltage.
The 7950X3D is the top-of-the-line mannequin, however we have not examined the $599 12-core Ryzen 9 7900X3D, which may also launch tomorrow — AMD does not plan to pattern this chip for printing. Nevertheless, if historical past is any indication, the 7900X3D ought to provide almost the identical gaming efficiency because the costlier 7950X3D. The $449 octa-core Ryzen 7 7800X3D is coming in late April, and that is undoubtedly the chip to beat: AMD tells us 3D V-Cache will provide the lion’s share of gaming efficiency, nevertheless it comes at a way more reasonably priced worth level.
There are some trade-offs, although – some video games do not make the most of 3D V-Cache, and the chip is not as quick as competing Intel chips in productiveness purposes. The 7950X3D additionally suffers from most of the woes we have seen within the newly launched AM5 platform — the motherboard ecosystem is costlier than Intel’s choices, and the stringent DDR5 requirement raises prices considerably in comparison with Intel’s DDR4-friendly platform.
In fact, worth is not all that vital for high-end gaming methods such as you’ll be constructing across the 7950X3D, and the chip attracts a lot much less energy than Intel’s Raptor Lake. This implies you may get a cooler, quieter machine with the quickest gaming processor cash should purchase, and you will do effectively in different CPU benchmarks. Intel has no comparable know-how to extend L3 cache capability, so the 7950X3D will maintain the gaming title for this technology of processors. We additionally discovered some new particulars about AMD’s second-generation 3D V-Cache know-how. Let’s take a better look.

Ryzen 9 7950X3D has 16 cores and 32 threads and solely works on AM5 platforms. On the floor, the 7950X3D appears to be like identical to a Ryzen 9 7950X with an additional L3 cache chip and extra silicon and software program tweaking. As earlier than, the 3D-stacked SRAM L3 chip weighs in at 64MB, so the 7950X3D comes with a whopping 144MB of complete cache, 128MB of which is the game-boosting L3 cache.
AMD’s Zen 4 3D V-Cache processors have a base TPD of 120 W and a most PPT of 162 W, though they’re 8, 12 and 16 cores. This implies the 7950X3D’s rankings are 68W decrease than the 170W/230W for the usual 7950X; this shall be efficient for heavy obligation work. The reductions are usually not fully shocking, as the extra cache chip may end up in barely greater working temperatures. The truth is, the 7950X3D’s most supported temperature is 89C, which is decrease than the 7950X’s restrict of 95C and the earlier technology 5800X3D’s restrict of 90C.
AMD has dramatically elevated enhance speeds with the brand new X3D fashions—the 7950X3D boosts it to five.7GHz, which is identical as the usual 7950X, which is a large leap over the 4.5GHz peak of the earlier technology 5800X3D. The bottom clock velocity is decreased by 200 MHz in comparison with the 7950X; this can be a essential adjustment for the decrease energy envelope. The chip does not include an included heatsink — AMD recommends a 280mm water cooler or higher for Ryzen 7000X3D processors.
AMD solely allowed overclocking of reminiscence and Infinity Material for the earlier technology 5800X3D, however will now permit each auto-overclocked Precision Increase Overdrive (PBO) and Curve Optimizer. AMD nonetheless does not permit direct frequency overclocking as a consequence of voltage limitation for one of many chips.
The $599 12-core 24-thread Ryzen 9 7900X3D peaks at 5.6GHz, the identical as the usual 7900X, whereas the bottom clocks drop by a comparatively small 300MHz. This chip comes armed with 104 MB cache, engraved as 96 MB L3.
The $449 Ryzen 7 7800X3D is akin to the first-gen Ryzen 7 5800X3D, however is the one CCD chip to return with a a lot quicker Zen 4 structure. The 8-core, 16-thread 7800X3D has 96MB of L3 cache, the identical core depend and cache capability because the earlier Zen 3. The 7800X3D has a base clock velocity of 4.2 GHz and a lift of 5.0 GHz, each greater than the 5800X3D’s 3.4 GHz base and 4.5 GHz enhance.
Each the 7950X3D and 7900X3D characteristic two octa-core Core Compute Die (CCD) chips, which suggests AMD is bringing 3D V-Cache know-how to the multi-CCD processor for the primary time. The picture above exhibits AMD putting in solely a single 7nm SRAM chip on prime of an octa-core CCD, leaving the opposite CCD clean.
This enables the 3D stacked SRAM-free chip to run at full velocity, thus offering the extremely accelerated clocks we see within the spec sheet for frequency rewarding purposes. In the meantime, the SRAM-stack CCD will run at a barely decrease clock velocity than the acceleration specified for the chip, however will meet the wants of purposes that worth low-latency entry, similar to video games. The chip itself has a 1.4 V peak, enabling excessive clock speeds, however the 3D V-Cache outfitted CCD has a ~1.1 V restrict to maintain thermals in examine.
Combining SRAM in only one CCD additionally lowers manufacturing prices, because the hybrid meeting course of and extra chip make this an costly know-how. AMD additionally says that utilizing two V-Cache chips does not present sufficient efficiency good points to justify the additional prices.
Both means, the brand new design requires the mixture of a brand new chipset driver and the Home windows Xbox Recreation Bar to position threads for various workload sorts on the correct chip. Sadly, AMD did not share many particulars in regards to the {hardware} implementation of the brand new second-generation 3D V-Cache, however we discovered lots of new particulars at a tech convention lately. Particulars of AMD’s thread concentrating on implementation and second-generation 3D V-Cache {hardware} could be discovered on the next pages; Then, we transfer on to the sport benchmarks.
