AMD is preparing a passively cooled X570S chipset. Warhol and Zen3 +?

At the end of the year, news came and went again about fanless X570 boards. It looks like there will really be a more economical version with passive cooling, it’s called the X570S. By the way, the news about “Zen 3+” is another thing, it probably doesn’t exist at all.

Some time ago (before CES 2021) there were reports that AMD might release a version X570 chipset with lower consumption. The X570 has a relatively high TDP and virtually all boards use active cooling because of this (which, however, often does not prevent high temperatures due to being placed near a heating graphics card), but some more economical version might be without a fan.

Meanwhile, the news died down and there seemed to be nothing in the plan. But now the documents showing the existence of a new version of this chipset have reappeared.

X570S?

According to the Eurasian economic database, a new batch of boards with a chipset marked X570S may be being prepared. Gigabyte has registered several models of motherboards, which, depending on how the marking works, should have a chipset marked this way. Sometimes, however, manufacturers register something that does not go on the market, so this may not be definitive proof. Combined with the fact that reports of a more economical version of the X570 have appeared before and this would fit into them, there could be something wrong with the phenomenon. The list of boards includes the following models:

  • X570S Aorus Master
  • X570S Aorus Elite
  • X570S Aorus Elite AX
  • X570S Aorus Pro AX
  • X570S Aorus Aero G
  • X570S Aorus Gaming X
  • X570SI Aorus Pro AX (probably Mini-ITX board)
  • X570S UD

Nicknamed “Moore’s Law is Dead” on Twitter, Youtuber then said that it really should be a refreshed chipset with reduced consumption and perhaps usually passive fanless cooling. The “S” in the name is supposed to mean “Silent”, ie quiet cooling. It does not say how big the reduction in TDP should be or if there will be any differences in equipment (for example, fewer PCIe 4.0 lines).

The AMD X570 chipset is a relatively large piece of silicon, which is probably related to the higher TDP. In fact, it is the same chip that serves as the IO chiplet in the Ryzen 3000 and 5000 processors (Source: techPowerUp)

So let’s hope that this is true and that the boards will finally come to the market, where there will also be modern connectivity and at the same time there will be no need to worry about the fan on the chipset.

No Zen3 +, Warhol will be more like XT models of the Ryzen 3000

The same youtuber Moore’s Law also mentions that AMD is probably not going to do anything like “Zen3 +”, which is quite speculatively speculated about (and I have to say that it came a lot from youtubers, although I don’t know if this one too). “Warhol” processors that should replace current Ryzeny 5000 “Vermeer” and to be the last generation of desktop CPUs on the AM4 platform (then Zen 4 and AM5 with “Raphael” processors), according to these speculations, they should contain an improved version of the Zen 3 kernel (hence Zen 3+) with a slightly higher IPC. And there has also been speculation that they would use a 6nm process, which would allow higher beats. This spread based on a speculative roadmap from the 3DCenter website.

In reality, however, all this was not based on a solid foundation, which is the closest escape roadmap shown by leaker MebiuW, parts of which have already been confirmed. But this roadmap for Warhol still lists the Zen 3 cores and still the 7nm process, indicating no change in equipment and architecture:

It is therefore very likely that Warhol will not be a new chip, but rather a refresch of Vermeer with the same silicon still on the 7nm process without EUV. The 6nm process is already with the EUV and would therefore require major changes to the chip design. Better reckon with the fact that Warhol could be something like XT models of Ryzen 3000, which differed only in the increased single-core turbo Boosts. Theoretically, for example, the Ryzen 7 5800XT and Ryzen 9 5900XT could have the maximum boost increased to 4.9 GHz, as the Ryzen 9 5950X has (with the possibility that in reality the maximum will be a bit higher). The Ryzen 5 5600XT should probably boost slightly lower. But 7nm silicon, like the 3000XT series, has no reserve for the frequency to move much higher.
