AMD on the Ryzen 7 9800X3D: ‘We have a lot to say’

AMD just revealed its Ryzen 9000 chips at Computex 2024, but the company is already working on its versions of these processors with 3D V-Cache. These X3D variants, as they’re called, have been a mainstay of AMD’s lineup since the Ryzen 7 5800X3D, and they consistently rank among the best gaming processors. AMD’s Donny Woligroski says the company is “not just resting on laurels,” and that it has some big plans for the next version of X3D chips.

The news comes from PC Gamer, which shared various quotes from an interview with Woligroski. Although we’ve known for a while that 3D V-Cache would come to Ryzen 9000 eventually, Woligroski says that AMD is pushing the tech forward. “It’s not like, ‘hey, we’ve also added X3D to a chip.’ We are working actively on really cool differentiators to make it even better. We’re working on X3D, we’re improving it,” Woligroski told PC Gamer.

AMD’s technical marketing manager stopped short of saying how the company is improving 3D V-Cache, but there are a ton of possibilities. Woligroski says that AMD has “a lot to say” on 3D V-Cache with Ryzen 9000, so it’s hard to imagine this is just some backend fluff that won’t amount to any meaningful improvements.

One of the big points of potential improvement comes down to AMD’s chiplet approach. Each AMD die can support up to eight cores, so 16-core processors like the Ryzen 9 7950X3D include two dies. However, only one of those dies includes the extra cache. That’s led to some strange situations, where the cheaper Ryzen 7 7800X3D with only a single die can outperform the more expensive Ryzen 9 7950X3D with its two dies.

There’s also the possibility of simply stacking more cache. With AMD pushing for AI in laptops and including integrated graphics on its desktop CPUs, additional cache would certainly help. Both graphics and AI workloads are hungry for memory, so if AMD is able to accelerate these workloads with additional cache close to the CPU, it could speed things up. Of course, AMD would need a way to actually leverage this additional cache, as up to this point, we haven’t seen 3D V-Cache scale with a larger pool in games.

The improvement I most want to see, however, is efficiency. In every case so far, X3D chips run at lower clock speeds than their X-series counterparts, despite drawing the same power. You also have little to no room for overclocking, with overclocking even being disabled on the Ryzen 7 5800X3D. If AMD is able to improve the thermal situation with the memory, or produce a more efficient core overall, that could mean we’ll see Ryzen 9000 X3D chips go further.

Although we know Ryzen 9000 X3D chips are coming, AMD hasn’t shared what models we’ll see. If AMD follows the previous generation, we should see the Ryzen 7 9800X3D, Ryzen 9 9900X3D, and Ryzen 9 9950X3D toward the end of the year. It’s possible that AMD will extend the 3D V-Cache tech to more CPU models, however, which would certainly lengthen the rollout.

Nice try, Intel, but AMD 3D V-Cache chips still win
A hand holding AMD's Ryzen 9 7950X3D processor.

Intel's freshly released Core i9-14900KS processor is advertised as the fastest CPU in the world, but does that mean AMD can never hope to compete, even with its flagship Ryzen 9 7950X3D? Not at all. Each CPU has its merits, and both are insanely powerful in their own right. At this price point and at this performance level, making the right choice is tricky.

Let's zoom in and find out how the Core i9-14900KS and the Ryzen 9 7950X3D stack up against each other, what they excel at, and which one is the better option to buy.

We have some good news about AMD’s next massive CPU launch
The Ryzen 5 7600X sitting among thermal paste and RAM.

For a while, AMD's highly anticipated new CPUs seemed like they had slipped to 2025. That would have been bad news for AMD, but according to some new reporting on the topic, Zen 5 chips may be getting announced sooner than we thought.

As reported by Paul Alcorn of Tom's Hardware, an AMD rep confirmed that the Zen 5 lineup is on track for a 2024 release, likely in the second half of the year. The information was shared during an AMD earnings call for the final quarter of 2023.

AMD is valiantly keeping its word to gamers
Someone holding the Ryzen 7 5800X3D in a red light.

AMD's aging AM4 platform has been around since 2016, and it's a socket that AMD has promised to support for "for many years." We thought we'd waved goodbye to AM4 for good, but a new leak says that AMD has two new 3D V-Cache chips in the works, namely the Ryzen 7 5700X3D and the Ryzen 5 5500X3D. If the rumor is to be believed, AMD may not be done with AM4 yet, which is great news for those hoping not to have to upgrade their entire PC just to get the latest performance.

As per the user @g01d3nm4ng0 on Twitter, the new chips will serve up the same massive L3 cache we've come to expect from AMD's X3D chips, making them solid options for gamers on a tighter budget. No one expected that AMD would keep releasing new versions of last-gen chips well over a year since the launch of the Ryzen 7000, and yet, it seems that they're in the works.
