Regular HH readers might recall that Saturday earlier than final, we reported on a rumor relating to the existence of processors based mostly on Zen 4 CPU cores that slot into extant AM4 motherboards. Frequent leaker Greymon55 urged that such a factor is feasible, however admitted that he wasn’t positive of the veracity of the knowledge.

In half, we’re accountable for this rumor. Speaking to us on YouTube, AMD’s Robert Hallock mentioned that AMD’s sockets, AM4 and AM5, are to “co-exist,” and that AM4 “has a lot of life.” However, he additionally did say that whereas there should still be extra CPUs for AM4, “nothing specifically is planned right now.” Speaking to Forbes, he was a bit of extra direct. Forbes‘ Antony Leather requested Hallock if the 5800X3D was the final processor for AM4, and Hallock mentioned “probably not.”

Well, Hungarian site ProHardver! was bored with the rumors, apparently, and went straight to the source: motherboard distributors. The site does not elaborate which distributors it spoke with, however based on ProHardver!, no such product is on the way in which. The site says that such a development—Zen 4 on AM4—can be very troublesome as a result of the AM5 socket is an LGA with a decrease backside peak, but the identical high peak as AM4’s PGA socket. The chiplets are apparently designed to utilize this additional vertical area, and so they won’t slot in an AM4 bundle.

ProHardver! goes on to say that, based on the businesses it spoke with, there’s one other product on the way in which for Socket AM4, however that it is one other Zen 3 design with 3D V-Cache. The processor in query would certainly be often known as the Ryzen 9 5900X3D, which is to say that it’s purportedly a twelve-core processor utilizing two CCDs, every topped with their very own 64MB 3D V-Cache chiplet.
Like this, however smaller and with solely two cube. So not likely like this.

That would give the chip a complete of 192 MB of L3 cache and positively make it a monster for gaming, however we now have to marvel in regards to the cost-benefit evaluation of such a processor. As we noticed in our evaluation of the processor in addition to our evaluation of the Falcon Northwest Tiki that got here strapped with it, the Ryzen 7 5800X3D provides killer efficiency for gaming, however productiveness duties—historically the factor that you simply use many-core CPUs for—do not achieve a lot in any respect. We suppose we’ll see if AMD springs it on us.
