AMD Introduces Three Ryzen 7000X3D V-Cache Chips and Three New Non-X 65W Processors

3D V-Cache for everyone.

Today at CES 2023, AMD announced six new Zen 4 Ryzen 7000 processors for its AM5 platform, with three new high-end Ryzen 7000X3D processors leading the charge with the company’s revolutionary 3D V-Cache in chips that top out at an incredible 5.7 GHz. This now-proven technology should enable AMD to unseat Intel’s powerful Raptor Lake processors from the top of our list of the best CPUs for gaming and our CPU benchmark hierarchy when they arrive in February.

The new high-performance AMD chips are available with eight, sixteen, and twenty-four cores, significantly expanding the lineup of 3D V-Cache chips compared to the single Ryzen 7 5800X3D model introduced with the first-generation chips. These new chips, according to AMD, will outperform Intel’s fastest gaming chip by as much as 24% in some games, resulting in astronomical generational performance gains.

AMD also announced three new 65W Ryzen 7000 “non-X” models that span the Ryzen 5 to Ryzen 9 families, thus providing a new lower level of entry to the AM5 platform to address some of the pricing issues associated with the company’s new AM5 platform. These chips are scheduled to arrive on January 10. During its CES 2023 keynote, AMD divulged a wealth of new information and benchmarks; let’s delve in.

As a reminder, AMD’s 3D V-Cache is a revolutionary new technology that 3D-stacks an additional SRAM chip vertically on top of the processor, thereby increasing the L3 cache capacity by 64MB and enabling explosive gaming performance gains (productivity workloads are unaffected). This technology made its debut in AMD’s Ryzen 7 5800X3D, the first ‘X3D’ model, which you can learn more about here. Intel does not have comparable technology, but it will soon release the 6-GHz Core i9-13900KS to maintain its gaming dominance.

AMD has not disclosed pricing information for its new X3D chips, but the company says they will be available in February. The Ryzen 9 7950X3D features 16 cores and 32 threads, a new record for 3D V-Cache-equipped processors. This chip is essentially a modified Ryzen 9 7950X with an additional L3 cache chiplet and additional tuning. As before, the 3D-stacked SRAM L3 chip weighs 64MB, so the 7950X3D comes with a monstrous 144MB of total cache, with 128MB of that being L3 cache for enhancing gaming performance. This chip will compete with Intel’s Core i9-13900K and the upcoming 6 GHz Core i9-13900KS.

AMD has specified the 3D V-Cache processors with a minimum TPD of 120W and a maximum PPT of 162W, which is less than the 170W/230W threshold for the 7950X. The additional cache chiplet can result in slightly higher operating temperatures, so this is not entirely unexpected. With the new X3D models, AMD has significantly increased the boost speeds. As a result, the 7950X3D boosts to 5.7 GHz, which is a significant improvement over the previous generation’s 5800X3D maximum of 4.5 GHz and the same as the standard 7950X. In comparison to the 7950X, there is a 200 MHz decrease, which is a necessary concession for the 120W TDP.

Due to its lower boost clock rate, the performance of the previous-generation model notoriously suffers in productivity applications; however, the 7950X3D’s higher clock rate suggests that we won’t see as much of a performance hit in productivity applications with the new Zen 4 models. However, threaded workloads will be impacted by a 50W reduction in available power.

The frequencies of all three new X3D chips are increased. The maximum frequency of the 12-core 24-thread Ryzen 9 7900X3D is 5.6 GHz, the same as the standard 7900X, while base clocks decrease by a relatively minor 300 MHz (base clocks are rarely used). This chip is equipped with 104MB of cache, of which 96MB is L3. This chip also falls into the lower 120W TDP range, so its performance in heavily threaded applications will also decrease.

AMD’s 7950X3D and 7900X3D are the first multi-CCD processors to feature two four-core chiplets, a first for the company. As shown in the image above, AMD only mounts a single SRAM chiplet on top of one CCD, leaving the other CCD unadorned. This allows the chiplet to operate at full speed without the 3D-stacked SRAM, delivering the high boost clocks listed on the spec sheet. In the meantime, the SRAM-stacked CCD will operate at a slightly slower clock speed than the chip’s rated boost.

AMD is collaborating with Microsoft on Windows optimizations that will function in tandem with a new AMD chipset driver to identify games that prefer the increased L3 cache capacity and pin them to the CCD with a stacked cache. Other games that favor higher frequencies over a larger L3 cache will be restricted to the CCD. AMD claims that the bare chiplet can access the stacked L3 cache in the adjacent chiplet, although this is not optimal and will be uncommon. Yes, the chip with the additional L3 cache will run games at a slower speed, but since the majority of games do not operate at peak clock rates, you should still see a significant performance boost.

The Ryzen 7 7800X3D is the only 7800X model available, so there is no direct comparison with Zen 4 processors. However, it is directly comparable to Ryzen 7 5800X3D from the first generation. The 8-core, 16-thread 7800X3D has the same cache size and number of cores as its Zen 3 predecessor. The 7800X3D has a base clock of 4. x and a boost clock of 5.0 GHz, both of which are higher than the 5800X3D’s base clock of 3.0 GHz and a boost clock of 4.5 GHz. The 7800X3D, like the other X3D chips, has a TDP of 120W, which is 15W higher than the 5800X3D and the current-generation eight-core Ryzen 7 7700X. These faster clock speeds and higher TDP, coupled with the more modern Zen 4 architecture, will result in performance improvements over both the 5800X3D and the 7700X. It is reasonable to assume that this chip will provide the lion’s share of the gaming benefits offered by X3D chips, so we anticipate that this model will be popular.

For the previous-generation 5800X3D, AMD only permitted memory and infinity fabric overclocking, not other forms of core overclocking. However, AMD will now permit both the auto-overclocking Precision Boost Overdrive (PBO) and the use of the Curve Optimizer. AMD informs us that the Curve Optimizer will maximize performance extraction, but both options are available. However, AMD prohibits direct frequency overclocking due to a 1.4V chip limit (this was a 1.1V limit with the previous-gen model).

As with all third-party tests, AMD provided some performance benchmarks, but you should take them with a grain of salt. These graphs also contain an unlabeled axis, which could be a non-zero axis that visually exaggerates performance deltas.

AMD demonstrated performance in stodgy titles that are frequently CPU-bound, so the advantages of the X3D architecture are evident, especially at the 1080p resolution used for testing. AMD claims the monstrous 16-core 7950X3D is between 13 and 24 percent faster than Intel’s flagship Core i9-13900K in these games. The Ryzen 7 5800X3D is an excellent gaming processor but performs poorly in application benchmarks. AMD claims that the 7950X3D is 4% to 52% faster than the Core i9-13900K in a variety of productivity benchmarks. This trade-off appears to be drastically reduced with the 7950X3D.

AMD’s benchmarks indicate that the Ryzen 7 7800X3D is anywhere from 21% to 30% faster than the 5800X3D in this selection of games. There are a few esports titles in this selection, and some games will either not benefit from the additional cache at all, or benefit less than others.

The 65W “non-X” Zen 4 Ryzen models have been eagerly awaited by value seekers, as they provide a lower cost of entry to the AM5 platform – a much-needed addition given the high cost of AM5 motherboards and the fact that Ryzen 7000 requires expensive DDR5 memory, whereas Intel’s chips can support either DDR4 or DDR5, giving it a cost advantage overall. In addition, the chips come with coolers that significantly improve the value proposition, and simply activating the auto-overclocking Precision Boost Overdrive (PBO) feature in conjunction with memory overclocking can produce nearly identical results to the X-series models. All of the new models have a base power of 65W and a maximum load power of 88W.

The Ryzen 9 7900 leads the pack with 12 cores and 24 threads, and you’ll notice that there is no non-X 7950X model, so 12 cores are the maximum you can purchase for a low-cost 65W chip. AMD has not yet disclosed the base frequency for any of the non-X models, though we expect it to be significantly lower than the 7900X to fit within the lower TDP rating. However, the 7900 is rated for a boost of up to 5.4 GHz. This is reasonable considering its lower 65W/88W TDP rating in comparison to the 7900X’s 170W/230W TDP rating. The remaining 7900 specifications are identical to those of the 7900X. The 7900 competes with the Core i9-13900 from Intel, but at a significantly lower price. This chip includes a competent RGB Wraith Prism cooler.

The Ryzen 7 7700 has eight cores and twelve threads for $329, which represents a small saving over the Ryzen 7 7700X’s $349 street price. This chip comes with a cooler while the 7700X does not, but we expect the 7700 to retail for significantly less than the suggested price. The maximum frequency of this chip is 5,1 GHz, 200 MHz slower than the 7700X. The 7700 will compete with the Core i7-13700 and includes the RGB-equipped Wraith Prism.

The Ryzen 7 7600 should be this generation’s value champion, just as the Ryzen 5 5600 was for the Zen 3 lineup. The 7600 has a boost frequency of 5.1 GHz, a 200 MHz decrease compared to the 7600X, and a Wraith Stealth cooler. This processor will compete with the Intel Core i5-13600.

AMD shared its performance benchmarks for the chips, highlighting a generational improvement of 7% to 31% in gaming and 12% to 48% in applications over Ryzen 9 5950X. Additionally, the company provided comparable benchmarks for the Ryzen 7 7700 over the previous-generation Ryzen 7 5800X and for the Ryzen 5 7600 over the Ryzen 5800X. These are remarkable generational improvements, but the lack of direct comparisons to Intel’s chips creates some ambiguity. As you might expect, reviews will soon be conducted to address any outstanding performance concerns.

Finally, AMD highlighted the advantages of its AM5 platform, including a PCIe 5.0 lane count advantage over Intel (24 vs 16) that allows your primary graphics card slot to continue operating at x16 when a PCIe 50 M.2 SSD is installed, whereas Intel’s slot will drop to x8. PCIe 5.0 SSDs are just now entering the market, so this may not be a significant advantage at the moment. However, AMD has pledged to support the platform until at least 2025, so it may become more significant in the future. AMD also shared a few benchmarks demonstrating that a Ryzen 9 7900 overclocked with the Wraith Stealth cooler yields a 34% increase in threaded work (Cinebench R23) and a 39% increase with water cooling. The company also presented the standard power/performance slide to illustrate the generational improvement in performance per watt.
