3D V-Cache Explained

Now is a great time to be an enthusiast looking to upgrade your computer thanks to Intel’s Alder Lake processors such as the i9-12900KS and AMD’s Ryzen 5800X3D. However with so many new advancements on this particular model from AMD, it’s important to know what exactly 3D V-Cache does and how it impacts system performance.

What is Processor Cache

Processor cache is a buffer of ultra-quick storage located on the CPU. It acts as an interface between system RAM and the processor, serving as system RAM when there’s enough space available, cutting down on the time it takes to access memory if there isn’t. We won’t go into specifics about how this technology works – because we all know that caches speed up recurring or commonly used calculations which helps out in terms of overall efficiency by reducing latency levels. In general, people overlook processors cache while they focus on core count and frequency – but without this factor then you will never truly understand what your computer can do.

Processor cache is classified into three levels – level one, two, and three – with level one being the quickest to access but least in memory storage size while level three is slower to access but larger in memory size.

What is AMD 3D V-Cache

The new 3D V-Cache may very well be the greatest invention for CPU cache since 10 years ago when AMD first introduced it. This time, they’re stacking it vertically and reducing the size of their own die – which means that they’ve been able to pack up to three times more than before! For example, on my Ryzen 7 5800X3D there is a whopping 96 MB of L3 vs the 32 MB in my previous generation’s Ryzen 5800X or 25 MB in Intel’s Core i7-12700k.

It is not just AMD’s consumer chips that make use of this new technology. Additionally, they provide server and datacenter solutions, including 3rd Gen Epyc models such as the Epyc 7773x and 7573x with 768MB of L3 VRAM.

How Does it Impact Performance?

Generally speaking, higher cache means better performance because it can calculate things faster than having to go out to the hard drive. With games in particular, there is always something being calculated or recalculated so a high-speed response time can make all the difference between playable and unplayable. Higher-end AMD processors offer this advantage – but whether it actually makes them the world’s fastest gaming desktop processor remains questionable. But when you look at their benchmark scores below, we see that they’re close enough where it might be worth considering one for gamers looking for a new machine; especially if you don’t want to spend an arm and leg on Intel’s equivalent processors.
