AMD launched their processors with 3D V-Cache technology in their 5000 series of desktop CPUs. The first of the 3D V-Cache equipped CPU was the AMD Ryzen 7 7800X3D. What this does is basically increases the CPU cache massively allowing for more memory access for the CPU and even the GPU with Smart Access Memory technology. They introduced the same technology too to the new Ryzen 7000 series CPUS rather recently on the AMD Ryzen 9 7950X3D, Ryzen 9 7900X3D, Ryzen 7 7800X3D, and AMD Ryzen 5 5600X3D.
How they massively increased the size of the cache available to their CPUs is by stacking the V-Cache module on top of their chips, hence the 3D moniker. Instead of spreading the memory module out and about, they stacked the memory modules to increase the height of the processor slightly and in turn increase the size of their cache. While it is a great solution to increase the CPU’s efficiency and effective speed, it is not so great for overclocking since stacking one chip over the other is not necessarily recommended in heat management. Still, we thought it was a great way to make your laptops more powerful without increasing power consumption by all that much or overclocking your chips. While this did not happen in the previous generation Ryzen CPUs, it is happening now with the new AMD Ryzen 9 7945HX3D made for laptops.
While it might seem like redundant technology for modern laptops, it is a clever technology that might allow you to fully take advantage of high-performing gaming laptops or creator focused laptops. Gaming laptops today come with high speed and high-resolution displays. In most cases, while resolution and detail are the GPU’s responsibility, frame rates and speed are determined by how much a CPU can process. That also means that you want a fast CPU to keep up with fast displays. That is where the 3D V-Cache technology comes in.
For the AMD Ryzen 9 7945HX3D, the 3D V-Cache bumps its memory to a whopping 144MB from the measly 64MB the regular Ryzen 9 7945HX packs. All its 16 cores still clock up to 5.4Ghz and offer about 55W of TDP. Thanks to a larger memory though, the CPU can process much faster than before and keep up with high-speed displays with ease. According to AMD, they have recorded a 15% boost in performance over the regular processor. They are also seeing massive gains even when TDP is at a low 40W.
This is a mobile CPU though, which means that you will not be able to find the chip out in the market on its own. You will find the AMD Ryzen 7945HX3D first in the ASUS ROG Strix SCAR 17 X3D in August of 2023. Of course, AMD is working with more partners to bring the X3D technology to more gaming laptops.
