In a nutshell: At the end of recently, an AMD report explaining the functions and specs of the upcoming 5000- series Threadripper Pro CPUs was dripped. It stated that all 5 designs would have dual-socket performance. Soon after, 2 Threadrippers appeared in the PassMark database having actually finished the standard in dual-socket mode – however they’re not from the 5000- series.

Instead, they were 2 of the seventeen-month-old flagship of the 3000- series: the 3995 WX. In theory, since the CPU shares its hardware with the dual-socket-capable Epyc 77 x2-series, the 3995 WX has actually just ever been avoided from participating in a dual-socket mode by software application restrictions.

Working in tandem, the 2 CPUs accomplished a rating of 123,631 points; 35%more than the mean outcome of a single 3995 WX, and the greatest rating of any two-CPU pairing in the database.

If the outcome is authentic, which it appears to be, then there’s just one most likely perpetrator: AMD themselves. It’s just too not likely that another celebration might customize the 2 CPUs, which cost some $8,800 each, and the requisite motherboard, effectively.

As for why AMD would be explore their old CPUs, our finest guess is that the development of the very first dual-socket sWRX8 motherboards for the 5000- series has actually raised some concerns about their backwards compatibility. A microcode upgrade might possibly make it possible for dual-socket performance in 3000- series CPUs, though AMD does not have much of a reward to develop one.

At a minimum, however, AMD does have a reward to allow dual-socket performance on the 5000- series. In the past, doing so would’ve cannibalized the Epyc series; it’s one of the highlights that separate the 2 line of product. As of 2022, the Epyc series will be a whole “generation” ahead of Threadripper and utilize a more recent architecture at a minimum, if not a more recent node.

Most of the offered details about the 5000- series originates from the previously mentioned report, which was gotten by Igor’s Lab. Its contents have not been validated beyond a couple of match-ups with other leakages, however Igor’s Lab is a credible source. That stated, often requirements are altered in the lead-up to the processors’ statement.

There’s now just Pro (with a “W”) variations of the processors, according to Igor’s Lab. This year, there are 5, up from 4; the addition was of the 24- core design.

On the whole, the specs of these processors aren’t too various from their predecessors. Their all-core clock speeds are a number of hundred megahertz greater or lower sometimes, however broadly comparable. Just their single-core clock speed is a constant upgrade of 250-350 MHz.

Like the Ryzen 5000- series, the greatest upgrade is under the hood: the Zen 3 architecture. In our screening, it might offer an IPC efficiency uplift of 10-20%in numerous applications. It may offer an even bigger uplift on higher-core count designs that gain from its remarkable inter-core and cache latency, significantly enhanced over the Zen 2 architecture of the 3000- series.

But it’s most likely to be the dual-socket performance driving the sales, ought to it eventuate. It would be fascinating to see what 128 opened cores can do.
