A Easier Slice of V-Cache For Gaming
In February, AMD launched the primary elements in its extremely anticipated Ryzen 7000X3D collection. This new line combines AMD’s 3D V-Cache packaging with high-performance and extremely environment friendly Zen 4 cores. Two out of the three X3D collection processors had been out there for the preliminary launch, together with the flagship Ryzen 9 7950X3D and the marginally lower-spec Ryzen 9 7900X3D. Nonetheless, AMD could have saved the perfect for final. Immediately, we might be trying on the third sibling from the Ryzen 7000X3D line-up, the long-awaited Ryzen 7 7800X3D.
The AMD Ryzen 7 7800X3D is the direct successor to final 12 months’s extremely profitable Ryzen 7 5800X3D, boasting 8 Zen 4 CPU cores, a base core frequency of 4.2 GHz, and a lift clock of as much as 5.0 GHz. However what units this processor aside from its predecessor is that it is utilizing AMD’s newest Zen 4 cores, constructed on TSMC’s 5 nm node, which guarantees to take energy and efficiency effectivity to the subsequent stage for avid gamers. Maybe the largest benefit of the Ryzen 7 7800X3D is its large 96 MB of L3 cache, due to AMD’s implementation of its 3D V-Cache packaging know-how in cooperation with TSMC. Our critiques of the earlier technology Ryzen 7 5800X3D and the behemoth Ryzen 9 7950X3D have proven this know-how to be a hit – generally, massively so – in particular video games which might be ready profit from the extra L3 cache.
Total, the Ryzen 7 7800X3D seems to be a promising addition to the Ryzen 7000X3D lineup. Its spectacular 96 MB of L3 cache and coming with the added advantages of Zen 4 cores make it a robust contender for avid gamers. Nonetheless, it stays to be seen the way it will carry out in real-world purposes in comparison with different present technology chips on take a look at, in addition to taking a look at how the efficiency in gaming stacks up.
AMD Ryzen 7 7800X3D: 8C/16T with 96MB of 3D V-Cache
Because it stands, the AMD Ryzen 7 7800X3D is one among three 8-core SKUs inside Ryzen 7000 collection, with all three pretty dissimilar CPUs concentrating on totally different markets. The Ryzen 7 7700X ($341) gives an unlocked multiplier for overclocking, with a base TDP of 120 W and PPT of 142 W; it provides extra energy to the cores for extra efficiency via AMD’s Precision Enhance Overdrive overclocking know-how. Though the Ryzen 7 7700 ($329) has the identical 8 x Zen 4 cores because the Ryzen 7 7700X, it advantages from a decrease base TDP of 65 W and a PPT worth of simply 88 W at inventory. This provides fans that need extra reasonably priced 8-core processor choices for both larger inventory efficiency with larger frequency and energy ranges or one thing with stable efficiency and distinctive energy effectivity with a sub-100 W energy output (from the CPU).
The third is the AMD Ryzen 7 7800X3D, which is primarily focused at avid gamers and, in the suitable conditions, can ship distinctive gaming efficiency with its 3D V-Cache packaging know-how. Trying to keep on from the success of its newest Ryzen 9 7950X3D ($699) and Ryzen 9 7900X3D ($599) with 3D V-Cache and construct upon the success of final 12 months’s Ryzen 7 5800X3D, the Ryzen 7 7800X3D has some very attention-grabbing points to its design that make it stand out from the remainder.

Referring to the principle specs of the Ryzen 7 7800X3D, it has 8 Zen 4 cores, working inside a base TDP of 120 W a most Bundle Energy Monitoring (PPT) worth of 162 W. Apparently, this is a rise in general energy from the Ryzen 7 5800X3D, which had a base TDP of 105.
issues on a generational foundation, each the Ryzen 7 7800X3D and Ryzen 7 5800X3D are 8 core designs. Nonetheless, the Ryzen 7 7800X3D has the benefit of coming with the extra performant and power-efficient Zen 4 cores, and from our critiques of AMD’s Ryzen 7000 collection processors, we have seen Zen 4 ship on each fronts. At AMD’s chosen clockspeeds, Zen 4 has additionally proven to be extra energy environment friendly than competing chips from Intel’s thirteenth Gen Core and former twelfth Gen Core collection, which may attain larger efficiency ranges, however burn a good bit extra energy in doing so.
One main profit of selecting the AMD Ryzen 7 7800X3D with its newest Zen 4 structure over its predecessor, the Ryzen 7 5800X3D, is by way of core frequencies. The earlier mannequin had a base clock of three.4 GHz and a turbo of as much as 4.5 GHz. Overclocking was additionally not supported by AMD, resulting in some limitations in compute efficiency. The Ryzen 7 7800X3D boasts sooner cores, with a 4.2 GHz base frequency (a 23% improve generationally) and a turbo of as much as 5.0 GHz (an 11% improve in most clock speeds in comparison with the Ryzen 7 5800X3D). In our earlier evaluation of the Ryzen 9 7950X3D ($699), which has two CCDs – one with 3D V-Cache and one with out – we discovered that the clockspeed limitation 3D V-Cache-equipped Zen 4 chiplet is 5.0 GHz, because the CCD with 96 MB of L3 cache on the Ryzen 9 7950X3D additionally topped out at 5.0 GHz there (in comparison with the common CCD boosting as much as 5.7 GHz).
AMD Ryzen 7 7800X3D: One CCD to Rule Them All
Referring to the CCD scenario with the Ryzen 7 7800X3D, in contrast to the opposite two V-Cache-equipped X3D Ryzen 7000 elements, the Ryzen 9 7950X3D and Ryzen 9 7900X3D, the Ryzen 7 7800X3D options one core complicated die (CCD) and one centralized I/O die. That is in distinction to the 7900 collection chips, which used two CCDs. To distinguish which every chip has by way of cores, and CCDs, I’ve dissected each under:
- Ryzen 9 7950X3D: 2 x CCDs (8C/16T every), 1 x CCD /w 96 MB L3 Cache, 1 x CCD /w 32 MB L3 Cache
- Ryzen 9 7900X3D: 2 x CCDs (6C/12T every), 1 x CCD /w 96 MB L3 Cache, 1 x CCD /w 32 MB L3 Cache
- Ryzen 7 7800X3D: 1 x CCD (8C/16T), 1 x CCD /w 96 MB L3 Cache
With the launch of the AMD Ryzen 9 7950X3D, which we previously reviewed in February, it has two CCDs, one with the usual 32 MB of L3 cache and the opposite boosted with a further 64 MB of 3D V-Cache layered on prime (96 MB L3 in complete). This design meant that AMD needed to get artistic to permit it to work in order that the perfect ranges of efficiency could possibly be delivered by way of each compute and gaming efficiency, avoiding sacrificing an excessive amount of of both. With this, AMD introduced out its PPM Provisioning and V-Cache Efficiency Optimizer drivers that work with Microsoft’s Home windows 11 (and 10) working system to leverage whichever CCD most closely fits the duty.
Working in tandem with Microsoft’s ‘Sport Mode’ constructed into the working system, when a recreation is loaded up on the Ryen 9 7950X3D, Sport Mode would detect this and feed the data to the Provisioning driver. AMD’s drivers, in flip, would deprioritize and park non-V-Cache enabled CCD, pushing the whole lot to run from the CCD with the 96 MB of 3D V-Cache. The second CCD could possibly be fired again up if sufficient work necessitated it (albeit nonetheless at a decrease precedence), however ideally, AMD tries to keep away from this in order that recreation threads aren’t repeatedly passing information between the 2 non-homogenous CCDs.
The Ryzen 7 7800X3D is actually the Ryzen 9 7950X3D with only one CCD (7950X3D has two)
In any other case, when working a extremely threaded non-game workload equivalent to video rendering, the chip would behave extra usually, making all 16 cores out there and prioritizing the vanilla CCD. On this case, the V-Cache CCD was primarily a second set of barely decrease clocked Zen 4 cores.
Shifting again to the Ryzen 7 7800X3D, one can be proper in pondering that it is principally simply the 3D V-Cache CCD of the Ryzen 9 7950X3D with out the upper spec CCD with the sooner Zen 4 cores. This tremendously simplifies the scheduling course of, as the only, homogenous CCD implies that no particular actions are wanted to account for the additional L3 cache.
Finally, AMD has created a type of two (and a half-ish) tiered system with its Ryzen 7000X3D lineup The Ryzen 9 7950X3D can supply the perfect of each worlds, with sooner cores of as much as 5.7 GHz on one CCD for these heavy compute workloads equivalent to video rendering and content material creation. On the identical time, the Ryzen 7 7800X3D gives loads of grunt with 8C/16T. Ideally, it might nonetheless ship top-tier gaming efficiency via the mixture of Zen 4 cores and 3D V-Cache, however with at a 36% cheaper price ($699 vs. $449).

Trying on the present desktop processor panorama regarding the Ryzen 7 7800X3D, there’s numerous competitors from AMD’s personal stack within the sub-$500 enviornment. This consists of AMD’s personal Ryzen 7 7700X ($349), which can be an 8C/16T SKU. It has sooner cores (as much as 5.4 GHz) and totally helps overclocking. Another choice is the Ryzen 7 7700. Though the Ryzen 7 7700 is a lower-powered 8C/16T half and does not profit from the 3D V-Cache for these video games that may leverage it, it additionally helps overclocking and is in the end cheaper at $329.
As for AMD’s competitors, the AMD Ryzen 7 7800X3D is up in opposition to Intel’s thirteenth Gen Core collection, particularly the Core i9-13900K and Core i7-13700K. Whereas the Core i7-13700K is in the identical value vary because the Ryzen 7 7800X3D, it is value noting that we did not obtain a pattern of this specific Intel processor for testing. As a substitute, we reviewed the Core i9-13900K and Core i5-13600K at their launch in October of final 12 months.

Each of the Intel processors talked about earlier ought to supply higher compute efficiency than the Ryzen 7 7800X3D as a result of, partly, they’ve extra cores. Nonetheless, AMD is moderately particularly concentrating on avid gamers with the Ryzen 7 7800X3D, so the largest competitors is within the gaming house, the place going past 8 CPU cores isn’t useful proper now. We have examined the Core i9-13900K and Core i5-13600K at 1080p, 1440p, and 4K resolutions. Surprisingly, the cheaper Core i5-13600K (14C/20T) carried out nicely, indicating that at larger resolutions, graphics card efficiency is extra vital than CPU energy in reaching larger framerates.
The AMD Ryzen 7 7800X3D is an efficient selection for avid gamers who do not require cutting-edge compute efficiency or have to create content material. It is also $250 cheaper than the Ryzen 9 7950X3D, leaving additional finances for a greater graphics card, which may improve the gaming expertise. The principle questions folks have are how the Ryzen 7 7800X3D compares to the competitors and the way it stacks up in opposition to the earlier Ryzen 7 5800X3D, particularly contemplating its value of $449. On this evaluation, we’ll reply each questions.
