AMD Unveils Ryzen 9 7950X3D, 7900X3D, and Ryzen 7 7800X3D, As much as 128 MB of L3 Cache And 5.7 GHz Enhance

Throughout Computex 22, AMD showcased its up to date CPU roadmap going via 2024, which yielded some thrilling propositions to the desktop processor market. A type of merchandise highlighted was a brand new 3D V-Cache SKU primarily based on Zen 4 cores, and with the success of its earlier Ryzen 7 5800X3D with 96 MB of 3D stacked V-Cache, players have been chomping on the bit for extra ever since. Utilizing their primetime keynote slot throughout CES 2023, AMD has unveiled its subsequent 3D V Cache-based processors to the market utilizing its Zen 4 core structure.

AMD hasn’t unveiled only one new Zen 4-based X3D SKU; it is asserting three throughout the Ryzen 7000 collection, the Ryzen 9 7950X3D, the Ryzen 9 7900X3D, and the Ryzen 7 7800X3D. Other than 64 MB of extra L3 cache via AMD’s 3D V-Cache stacking know-how, which is a 3D chiplet stacking know-how at the side of TSMC, all three Zen 4 X3D SKUs characteristic a 120 W TDP. In addition they have increased increase core frequencies than earlier X3D chips, with the Ryzen 9 7950X3D boosting as much as a formidable of 5.7 GHz on the core.

AMD and 3D Chiplets: Stacking L3 Cache For Players

Since AMD launched its first desktop processor that includes its 3D V-Cache packaging know-how, the Ryzen 7 5800X3D, it has given customers and players a style of the advantages that giant swimming pools of L3 cache can have on framerates in CPU-limited eventualities. Specializing in the earlier Ryzen 7 5800X3D, AMD and TSMC added 64 MB SRAM chiplet onto the highest of the prevailing 32 MB via a direct copper-to-copper bonding TSV to make sure circuit integrity.

The strategy consists of die thinning, desiring to allow parity between the 3D stacked chiplet, the remainder of the silicon, and the built-in warmth spreader (IHS) in order that it suits inside the identical general platform body, e.g., cooler and compatibility. Because the Ryzen 7 5800X3D and its 96 MB of stacked L3 V-Cache displayed vital enhancements in particular titles, the additional L3 cache did not present that efficiency achieve in different titles; there nonetheless is not an official record of video games that profit from further L3 cache.

The primary caveat with the Ryzen 7 5800X3D got here via its compute efficiency. With slower general core clock speeds than the Ryzen 7 5800X, it suffered in duties akin to rendering, encoding, and any process or workload that did not profit from massive quantities of L3 cache. It seems as if AMD thought of that and did it higher.

Beneath is an inventory of our detailed protection of AMD’s Ryzen 7000 desktop processors and its 3D V-Cache packing know-how:

Ryzen 9 7950X3D: New Flagship For Gaming with 128 MB L3 Cache, As much as 5.7 GHz

AMD has gone all out with its 3D V-Cache packaging know-how with the announcement of AMD Ryzen 9 7950X3D, a 16-core, 32-threaded behemoth with 128 MB of L3 cache, and a lift core clock velocity of as much as 5.7 GHz. Whereas we noticed some concessionary trade-offs between the earlier technology Ryzen 7 5800X3D in computation efficiency, this was defined by decrease voltages, necessitating a decrease core base frequency and a decrease core increase frequency. Consequently, pure CPU compute efficiency declined in distinction to the Ryzen 7 5800X.  

The newest Ryzen 7000 X3D SKUs look to alleviate a lot of the earlier discrepancies in efficiency like we noticed with the Ryzen 7 5800X3D and 5800X, by permitting for related peak turbo clock speeds with out interfering with the integrity of the stacked silicon within the 3D V-Cache stack.

We now have reached out to AMD to verify how they managed to safe the integrity with a a lot larger increase clock velocity than the earlier Ryzen 7 5800X3D. Nonetheless, with the effectivity of TSMC’s 5 nm node and performance-per-watt improve with AMD’s Zen 4 core structure over the 7 nm Zen 3 core, we imagine this mixture is among the causes how they managed it. We now have additionally reached out to AMD on whether or not or not the Ryzen 7000 X3D processors are unlocked or if overclocking by way of the frequency multiplier is disabled. As soon as we obtain a reply, we are going to replace this piece with their response.

Opening with the flagship SKU, the Ryzen 9 7950X3D shares lots of the identical traits because the Ryzen 9 7900X, together with 16-cores and 32-threads and a turbo frequency of as much as 5.7 GHz. The improved chip provides 128MB of L3 cache, which is comprised of 64 MB of present pooled L3 cache within the CCDs, and one other 64 MB sliced on prime with TSVs (presumably putting 64MB on one CCD, creating an unbalanced cache). Curiously, the official TDP can also be a lot decrease, with the chip rated at 120 W versus 170 W for the common 7950X. Consequently, the 7950X3D has a decrease base core frequency of 4.2 GHz, versus 4.5 GHz. Though the Ryzen 9 7950X3D has a 300 MHz slower base frequency, having the identical turbo frequency of 5.7 GHz implies that peak efficiency could be related, although in closely multithreaded conditions the decrease TDP is undoubtedly going to come back into play.

AMD is competing on the prime finish of the x86 desktop market with its 16-core choices, each in compute and gaming. Nonetheless, AMD has additionally readied a 12-core answer with their X3D chiplet packaging know-how, the Ryzen 9 7900X3D. Sitting alongside the Ryzen 9 7900X within the stack, the Ryzen 9 7900X3D has double the L3 cache (128 vs. 64 MB) and the identical 4.4 GHz increase core clock velocity. The one variations are available in the best way of base frequencies and energy consumption, with the Ryzen 9 7900X3D having the identical 120 W TDP as the entire new Ryzen 7000 X3D-based SKUs, which as a consequence, does drop the bottom core frequencies down from 4.7 GHz to 4.4 GHz; a 300 MHz drop on base.

Ryzen 7 7800X3D: Just like the Ryzen 7 5800X3D, However Higher

The ultimate and third X3D SKU is the Ryzen 7 7800X3D processor, the direct successor, and alternative to the earlier Ryzen 7 5800X3D. Sharing the identical massive 96 MB of L3 cache, AMD has improved the specs with a sooner increase core clock velocity of as much as 5 GHz, together with the residual advantages that AMD’s Zen 4 TSMC 5 nm core brings to the desk in each efficiency, IPC uplift, and performance-per-watt effectivity.

AMD has additionally supplied their in-house figures on the Ryzen 9 7800X3D versus the Ryzen 7 5800X3D, together with a claimed 21% uplift in efficiency at excessive 1080p settings, 22% in Warhammer Daybreak of Battle 3, and 23% in CS: GO framerates. Additional to those efficiency claims, AMD claims that the Ryzen 9 7800X3D has an uplift of 30% in DOTA 2. AMD hasn’t supplied any in-house information surrounding compute efficiency or gaming efficiency information for the Ryzen 9 7950X3D or Ryzen 9 7900X3D processors.

All three of AMD’s newest X3D-based 3D V-Cache packaged processors, together with the Ryzen 9 7950X3D, the Ryzen 9 7900X3D, and the Ryzen 7 7800X3D, might be out there in February 2023. Though it hasn’t supplied data surrounding the anticipated MSRP of every CPU, the Ryzen 7 5800X3D got here with a $100 premium over the common Ryzen 7 5800X. We anticipate that there might be not less than an identical worth premium.

With worth drops already in drive for the non-X3D SKUs already in the marketplace, such because the Ryzen 9 7900X, there could possibly be room for the Ryzen 7000 X3D SKUs to fit in on the unique MSRPs of every corresponding processor within the household.
