AMD is ready to battle Intel with next-gen 3D V-Cache CPUs

AMD is rumored to already have a working Zen 4 3D V-Cache chip, suggesting that it hopes to deal a large blow to Intel sooner than expected. An early sample of the CPU blew its predecessors out of the water in certain benchmarks.

If AMD is accelerating its launch strategy for the successor to the Ryzen 7 5800X3D, should Intel be worried? Today’s leaks indicate the answer is a tentative “yes, it probably should.”

Speculations about the upcoming AMD Zen 4 3D V-Cache chips.
Moore's Law Is Dead

Leaker Moore’s Law Is Dead has just released an in-depth video about the upcoming Ryzen 7000 3D V-Cache chips. AMD itself has confirmed that it will bring back the highly successful tech we already know from the Ryzen 7 5800X3D, but it didn’t say much else.

Now, Moore’s Law Is Dead swoops in with a fresh round of leaks citingAMD sources to back up these claims. As always, it’s best to approach them with a hint of doubt, but it’s also worth noting that the YouTuber does often present accurate information ahead of time. Now, assuming you’ve come prepared with that healthy pinch of skepticism, let’s dive in.

According to the recent video, the 3D V-Cache found on Zen 4 processors will represent the second generation of the tech, and as such, it will bring several improvements in terms of performance. This will help it keep up with the faster on-die L3 cache on the Zen 4 chiplets. Moore’s Law Is Dead always cites several sources with different levels of confidence, but one sentiment seems to echo across these reports — we’re about to see a substantial performance gain.

This seems to be true not just for 3D V-Cache chips, but for Zen 4 as a whole. Based on an internal AMD comparison done with constrained TDP levels, Zen 4 CPUs showed a clear performance lift, and the 3D V-Cache version only brought that up even more. Compared to a basic Zen 4 chip, the 3DV version was up to 30% faster.

The YouTuber was allegedly given some internal AMD benchmarks that compared the Zen 3, Zen 3 X3D, Zen 4 (A0), and Zen 4 X3D (A0) chips to one another. These benchmarks don’t tell us much, but it’s clear that Zen 4 3D has the potential to destroy other chips in some regards — and this includes Intel Raptor Lake.

Intel had the upper hand over AMD thanks to being able to release Alder Lake CPUs so much earlier. Introducing DDR5 RAM and PCIe Gen 5.0, those processors proved to be successful, although the flagships (such as the Core i9-12900KS) were really expensive. This gap is about to close. AMD already inched closer when it showed off the true power of the 3D V-Cache earlier this year, and now the manufacturer plans to continue down that same path.

So far, the predicted timeline tells us that AMD will launch the top Ryzen 7000 CPUs on September 27; at the same time, its partners will launch the high-end AM5 motherboards. Intel Raptor Lake will come next, but AMD is unlikely to stay dormant. It will follow up with budget Ryzen CPUs and motherboards, and soon may possibly tease the Zen 4 X3D, which would almost certainly give Intel a run for its money both in terms of raw performance and cost to performance.

Intel Raptor Lake might well outperform Zen 4 this year, or it might not — it’s too early to say one way or the other. But what will Intel do once AMD strikes back with these 3D V-Cache beasts? If they turn out to be as good as they seem, Intel might indeed have reasons to be worried.

4 CPUs you should buy instead of the Ryzen 7 7800X3D

The Ryzen 7 7800X3D is one of the best gaming processors you can buy, and it's easy to see why. It's easily the fastest gaming CPU on the market, it's reasonably priced, and it's available on a platform that AMD says it will support for several years. But it's not the right chip for everyone.

Although the Ryzen 7 7800X3D ticks all the right boxes, there are several alternatives available. Some are cheaper while still offering great performance, while others are more powerful in applications outside of gaming. The Ryzen 7 7800X3D is a great CPU, but if you want to do a little more shopping, these are the other processors you should consider.

AMD’s next-gen CPUs are much closer than we thought
AMD Ryzen 7 7800X3D held between fingertips.

We already knew that AMD would launch its Zen 5 CPUs this year, but recent motherboard updates hint that a release is imminent. Both MSI and Asus have released updates for their 600-series motherboards that explicitly add support for "next-generation AMD Ryzen processors," setting the stage for AMD's next-gen CPUs.

This saga started a few days ago when hardware leaker 9550pro spotted an MSI BIOS update, which they shared on X (formerly Twitter). Since then, Asus has followed suit with BIOS updates of its own featuring a new AMD Generic Encapsulated Software Architecture (AGESA) -- the firmware responsible for starting the CPU -- that brings support for next-gen CPUs (spotted by VideoCardz).

Intel may fire the first shots in the next-gen GPU war

The GPU market is about to start heating up in just a few short months, and that's not just due to AMD and Nvidia. According to a new report, Intel plans to release its highly anticipated, next-gen Arc Battlemage graphics cards sooner than many have expected, and the GPUs might drop at just the perfect time to steal some sales away from AMD and Nvidia.

The tantalizing news comes from a report by ComputerBase. The publication claims that during Embedded World 2024, an event that took place in Germany, Intel's partners implied that Arc Battlemage GPUs might launch before this year's Black Friday. Realistically, this implies that Intel would have to hit the market in early November at the latest, giving its partners and retailers enough time to make the products readily available during the Black Friday shopping craze.
