AMD’s X3D V-Cache tech is coming to Threadripper and next-gen APUs – Leaker Claims

It sounds like AMD’s X3D technology is coming to more products moving forward

Following reports of AMD’s plans for Ryzen Threadripper X3D CPUs, another source has confirmed the existence of this V-Cache-enhanced monster CPU range. zhangzhonghao, a well-known hardware leaker, AMD’x X3D tech is indeed coming to their Ryzen Threadripper CPU lineup. Additionally, the leaker revealed that AMD’s 3D V-Cache technology is coming to other next-generation AMD products.

Regarding Threadripper, zhangzhonghao noted that CCDs on AMD’s X3D CPUs will be “all stacked”. This means that all CCDs on AMD’s Ryzen Threadripper X3D CPUs will feature 3D V-Cache. This makes sense now that AMD has been able to achieve higher clocks speeds with their latest X3D CPUs.

With AMD’s next-generation “Halo-level” APUs, AMD will reportedly add its 3D V-Cache to boost the performance of its CPU and GPU components. This makes sense, given these products’ often bandwidth-starved nature.

AMD’s X3D V-Cache technology makes a lot of sense for a “Halo-level” APU

Adding 3D V-Cache to AMD’s next-generation version of “Strix Halo” would be a great move for AMD to make. After all, this chip would aim to deliver discrete-level GPU performance and high-end CPU performance within a single mobile-friendly package.

AMD’s Strix Halo APU will reportedly launch in 2025 with 16 Zen 5 CPU cores and an RDNA 3.5 GPU with 40 compute units. The GPU is said to deliver performance levels similar to those of an RTX 4070 (mobile), and its next-generation counterpart should be even stronger.

As mentioned before, AMD’s APUs are often bandwidth-starved. While AMD’s X3D V-Cache technology is often used to deliver performance gains through decreased data access latencies (accessing data on cache is orders of magnitude faster than accessing data on DRAM), it also frees up bandwidth on higher-level memory pools.

Adding 3D V-Cache to an APU will free up system memory bandwidth, which could be used elsewhere. This makes AMD’s X3D technology doubly beneficial. It will give their next-gen “Halo” APUs the same X3D benefits as existing CPUs. Furthermore, it will free up bandwidth that can speed up other areas of the SOC.

With this X3D APU, AMD could use V-Cache on just the CPU (or GPU), on both the CPU and GPU (separately), or on both using a shared X3D cache. Regardless of what way AMD uses it, it will boost overall SOC performance. That’s good news for AMD, and their future laptop customers.
