The precise benefits that this new cache technology provides are yet to be seen, as it’s not currently used in any available AMD processors. Depending on the size of each of the stacked caches, we could see up to 128 or even 192 megabytes of 元 cache storage! This is similar in some ways to the HBM tech that AMD introduced to graphics card memory a few years back. Essentially, this allows “stacking” of 元 caches rather than placing them adjacently, creating potential for an enormous amount of memory and bandwidth. 元 tends to have a fairly large impact on gaming, with most modern processors having anywhere from 12 to 64 megabytes of 元 cache.ĭue to some new hardware technology that AMD is currently working on, at least part of the Zen 4 series will likely support what AMD calls “3D vertical cache”. There are three different common forms of processor caches: L1, which is fast and has a low capacity L2, which is moderate in both speed and capacity and 元, which is the largest and slowest. What even is a cache in a processor? We’ve touched on this before, but to put it simply, the “cache” is to the CPU as the RAM is to the rest of your computer it works at a very high speed, and stores short-term information that the processor needs to function optimally. Three-Dimensional Caching (On Higher-end Chips) But Intel users are probably used to socket compatibility woes for upgrades anyway. Pretty convenient! Well, unless you’re coming from an Intel board, of course. Interestingly, the AM5 socket retains the same form factor for cooling devices as the AM4 socket, allowing you to keep using your previous CPU cooler if you have one of AMD’s Zen 3 processors. But the other perks of the new AM5 boards should be well worth it. As for the update to PCIe 5.0, truthfully most graphics cards don’t even reach the maximum bandwidth of PCIe 4.0 or even PCIe 3.0, so PCIe 5.0 isn’t going to revolutionize… anything, really. When pins are on the board instead of the processor, it typically allows them to be stronger and less prone to damage from bending. DDR5 RAM remains expensive for the time being, but hopefully we’ll see prices deflate throughout the year to make a Ryzen 7000 build a little easier on the wallet.ĪM5 will also introduce a switch to LGA for the contacts, meaning the back of the processor is flat and covered with contacts rather than pins. There, they stated it would use a new AM5 motherboard socket, which will introduce support for both DDR5 RAM and PCIe 5.0 slots, bringing its compatibility in line with Intel’s 12 th generation of processors. We can most likely expect a release before the holiday season… but this is the facts section of the article, so get that speculation outta here! AM5 = DDR5 + PCIe 5.0ĪMD announced most of the info we currently know about Zen 4 processors at CES 2022 in January. It shouldn’t be too long before AMD announces a more solid release date, especially considering “H2 2022” is less than 4 months away from now. That’s quite a significant amount of time in the quickly evolving realm of CPUs! Considering Intel’s 12 th generation processors released in November 2021, AMD is taking potentially over 12 months to release their competition to the Alder Lake lineup. The Zen 4 platform of CPUs was scheduled to release in early 2021, but due to the massive supply shortages (that feel like they will never end), it got pushed back ~18 months to H2 2022. While we know the release window for the Zen 4 lineup is the second half of 2022, we don’t know anything more specific than that, like a release date.
