During Computex 22, AMD showcased its updated CPU roadmap going done 2024, which yielded immoderate breathtaking propositions to the desktop processor market. One of those products highlighted was a caller 3D V-Cache SKU based connected Zen 4 cores, and with the occurrence of its erstwhile Ryzen 7 5800X3D with 96 MB of 3D stacked V-Cache, gamers person been chomping astatine the spot for much ever since. Using their primetime keynote slot during CES 2023, AMD has unveiled its adjacent 3D V Cache-based processors to the marketplace utilizing its Zen 4 halfway architecture.

AMD hasn't unveiled conscionable 1 caller Zen 4-based X3D SKU; it's announcing 3 crossed the Ryzen 7000 series, the Ryzen 9 7950X3D, the Ryzen 9 7900X3D, and the Ryzen 7 7800X3D. Aside from 64 MB of further L3 cache done AMD's 3D V-Cache stacking technology, which is simply a 3D chiplet stacking exertion successful conjunction with TSMC, each 3 Zen 4 X3D SKUs diagnostic a 120 W TDP. They besides person higher boost halfway frequencies than erstwhile X3D chips, with the Ryzen 9 7950X3D boosting up to an impressive of 5.7 GHz connected the core.

AMD and 3D Chiplets: Stacking L3 Cache For Gamers

Since AMD released its archetypal desktop processor featuring its 3D V-Cache packaging technology, the Ryzen 7 5800X3D, it has fixed users and gamers a sensation of the benefits that ample pools of L3 cache tin person connected framerates successful CPU-limited scenarios. Focusing connected the erstwhile Ryzen 7 5800X3D, AMD and TSMC added 64 MB SRAM chiplet onto the apical of the existing 32 MB done a nonstop copper-to-copper bonding TSV to guarantee circuit integrity.

The method includes dice thinning, intending to alteration parity betwixt the 3D stacked chiplet, the remainder of the silicon, and the integrated vigor spreader (IHS) truthful that it fits wrong the aforesaid wide level frame, e.g., cooler and compatibility. As the Ryzen 7 5800X3D and its 96 MB of stacked L3 V-Cache displayed important improvements successful circumstantial titles, the other L3 cache didn't supply that show summation successful different titles; determination inactive isn't an authoritative database of games that payment from other L3 cache.

The main caveat with the Ryzen 7 5800X3D came done its compute performance. With slower wide halfway timepiece speeds than the Ryzen 7 5800X, it suffered successful tasks specified arsenic rendering, encoding, and immoderate task oregon workload that didn't payment from ample amounts of L3 cache. It looks arsenic though AMD considered that and did it better.

Below is simply a database of our elaborate sum of AMD's Ryzen 7000 desktop processors and its 3D V-Cache packing technology:

• AMD Zen 4 Ryzen 9 7950X and Ryzen 5 7600X Review: Retaking The High-End
• AMD's Desktop CPU Roadmap: 2024 Brings Zen 5-based "Granite Ridge"
• AMD Zen Architecture Roadmap: Zen 5 successful 2024 With All-New Microarchitecture
• AMD Zen 4 Update: 8% to 10% IPC Uplight, 25% More Per-Per-Watt, V-Cache Chips Coming
• AMD Demonstrates Stacked 3D V-Cache Technology: 192 MB astatine 2 TB/sec

Ryzen 9 7950X3D: New Flagship For Gaming with 128 MB L3 Cache, Up to 5.7 GHz

AMD has gone each retired with its 3D V-Cache packaging exertion with the announcement of AMD Ryzen 9 7950X3D, a 16-core, 32-threaded behemoth with 128 MB of L3 cache, and a boost halfway timepiece velocity of up to 5.7 GHz. While we saw immoderate concessionary trade-offs betwixt the erstwhile procreation Ryzen 7 5800X3D successful computation performance, this was explained by little voltages, necessitating a little halfway basal frequence and a little halfway boost frequency. Consequently, axenic CPU compute show declined successful opposition to the Ryzen 7 5800X.  

The latest Ryzen 7000 X3D SKUs look to alleviate overmuch of the erstwhile discrepancies successful show similar we saw with the Ryzen 7 5800X3D and 5800X, by allowing for akin highest turbo timepiece speeds without interfering with the integrity of the stacked silicon successful the 3D V-Cache stack.

We person reached retired to AMD to corroborate however they managed to unafraid the integrity with a overmuch greater boost timepiece velocity than the erstwhile Ryzen 7 5800X3D. Still, with the ratio of TSMC's 5 nm node and performance-per-watt upgrade with AMD's Zen 4 halfway architecture implicit the 7 nm Zen 3 core, we judge this operation is 1 of the reasons how they managed it. We person besides reached retired to AMD connected whether oregon not the Ryzen 7000 X3D processors are unlocked oregon if overclocking via the frequence multiplier is disabled. Once we person a reply, we volition update this portion with their response.

Opening with the flagship SKU, the Ryzen 9 7950X3D shares galore of the aforesaid characteristics arsenic the Ryzen 9 7900X, including 16-cores and 32-threads and a turbo frequence of up to 5.7 GHz. The enhanced spot offers 128MB of L3 cache, which is comprised of 64 MB of existing pooled L3 cache successful the CCDs, and different 64 MB sliced connected apical with TSVs (presumably placing 64MB connected 1 CCD, creating an unbalanced cache). Curiously, the authoritative TDP is besides overmuch lower, with the spot rated astatine 120 W versus 170 W for the regular 7950X. Consequently, the 7950X3D has a little basal halfway frequence of 4.2 GHz, versus 4.5 GHz. Although the Ryzen 9 7950X3D has a 300 MHz slower basal frequency, having the aforesaid turbo frequence of 5.7 GHz means that highest show tin beryllium similar, though successful heavy multithreaded situations the little TDP is undoubtedly going to travel into play.

AMD is competing astatine the apical extremity of the x86 desktop marketplace with its 16-core offerings, some successful compute and gaming. Still, AMD has besides readied a 12-core solution with their X3D chiplet packaging technology, the Ryzen 9 7900X3D. Sitting alongside the Ryzen 9 7900X successful the stack, the Ryzen 9 7900X3D has treble the L3 cache (128 vs. 64 MB) and the aforesaid 4.4 GHz boost halfway timepiece speed. The lone differences travel successful the mode of basal frequencies and powerfulness consumption, with the Ryzen 9 7900X3D having the aforesaid 120 W TDP arsenic each of the caller Ryzen 7000 X3D-based SKUs, which arsenic a consequence, does driblet the basal halfway frequencies down from 4.7 GHz to 4.4 GHz; a 300 MHz driblet connected base.

Ryzen 7 7800X3D: Like the Ryzen 7 5800X3D, But Better

The last and 3rd X3D SKU is the Ryzen 7 7800X3D processor, the nonstop successor, and replacement to the erstwhile Ryzen 7 5800X3D. Sharing the aforesaid ample 96 MB of L3 cache, AMD has improved the specifications with a faster boost halfway timepiece velocity of up to 5 GHz, on with the residual benefits that AMD's Zen 4 TSMC 5 nm halfway brings to the array successful some performance, IPC uplift, and performance-per-watt efficiency.

AMD has besides provided their in-house figures on the Ryzen 9 7800X3D versus the Ryzen 7 5800X3D, including a claimed 21% uplift successful show astatine precocious 1080p settings, 22% successful Warhammer Dawn of War 3, and 23% successful CS: GO framerates. Further to these show claims, AMD claims that the Ryzen 9 7800X3D has an uplift of 30% successful DOTA 2. AMD hasn't provided immoderate in-house information surrounding compute show oregon gaming show information for the Ryzen 9 7950X3D oregon Ryzen 9 7900X3D processors.

All 3 of AMD's latest X3D-based 3D V-Cache packaged processors, including the Ryzen 9 7950X3D, the Ryzen 9 7900X3D, and the Ryzen 7 7800X3D, volition beryllium disposable successful February 2023. Although it hasn't provided accusation surrounding the expected MSRP of each CPU, the Ryzen 7 5800X3D came with a $100 premium implicit the regular Ryzen 7 5800X. We expect that determination volition beryllium astatine slightest a akin terms premium.

With terms drops already successful unit for the non-X3D SKUs already connected the market, specified arsenic the Ryzen 9 7900X, determination could beryllium country for the Ryzen 7000 X3D SKUs to slot successful astatine the archetypal MSRPs of each corresponding processor successful the family.
