AMD has produced a new processor from APU waste chips for consoles. The 4800S Desktop Kit probably has eight Zen 2 cores again, and the board should handle faster graphics cards, maybe even PCIe 4.0.
Obscure hardware has been thriving lately, thanks in part to the fact that AMD has begun recycling x86 APUs used in consoles and selling them as PC processors. After Jaguarech from Xbox One appeared this year AMD 4700S Desktop Kit, which was a processor with eight Zen 2 cores, which arises from defective pieces of APUs for the PlayStation 5. AMD now seems to be preparing another such processor, now designated the 4800S. And the board with it should be better for gaming use.
VideoCardz informs that it got photos of a new version of the board with such a recycled console chip, which is called AMD 4800S Desktop Kit. These processors are probably not sold separately, but directly with the whole board, so they will probably always appear with the same PCB. That’s why their name is AMD 4700S (or now 4800S) Desktop Kit.
While the 4700S version had a mini-ITX board with only one PCI Express × 16 slot (which in reality has perhaps only PCIe 2.0 × 4 connectivity), the AMD 4800S Desktop Kit is a multi-slot mATX board: long PCI Express × 16, one short PCIe × 1 and then another M.2 slot for a wireless module, which will probably also need one PCI Express line. And to the right of the processor (so with the advantage of cooling by blowing from the CPU cooler) there is also an M.2 slot for the SSD. It is not yet completely clear what connectivity the PCI Express × 16 graphics slot really has, according to VideoCardz, it could allegedly even support PCIe 4.0, but it is probably not certain yet.
The board also probably has four SATA ports for disks, SSDs and optical drives. The power supply is classically an ATX source. Interestingly, the photo shows two different passive heatsinks, almost as if the board had a chipset with a separate north and south bridge. This was not the case with the 4700S, it only had the smaller of the two liabilities on the chipset (AMD A77E, so it is a derivative of chipsets for a 28nm APU to the FM2 + socket). So we think the chipset is still smaller. The second and larger passive could be the PCI Express switch, which makes the limited number of lines provided by the processor more for the chipset and PCIe slots. This seems like the most logical, albeit inelegant, option.
Compatibility with heatsinks for AM4?
According to the photos, the board again probably uses GDDR6 memories, which are permanently powered on the bottom of the board (where the backplate is cooled by the 4700S). The 4700S board had its own special heatsink, but in the case of the 4800S Desktop Kit, it can be seen that the mounting holes corresponding to the heatsinks for the AM4 socket are used – Wraith Stealth seems to be used. This might allow a wide range of heatsinks to be used, but we don’t know if the difference between the height of the BGA processor and the CPU in the AM4 socket is somehow solved. In the end, it is not possible to use a number of heatsinks through the same holes, as they would be too high after installation. It will also probably be a good idea to choose a top flow cooler and not a tower cooler, because the VRMs on the left of the processor do not have passive coolers and should be blown directly for safety.

We don’t know yet what the parameters of the processor are, but it should probably have eight Zen 2 cores again, maybe at a slightly higher frequency than the 4700S, which has a clock speed of 3.6-4.0 GHz (unless a higher number in the 4800S indicates only better connectivity). Theoretically, it could be the same silicon as in the 4700S board, but it is also possible that instead of the recycled PS5 production, it is now an APU for Xbox Series S nebo Xbox Series X.
Available in a bundle with the Radeon RX 6600
Either way, the integrated graphics core may not be active again, and the chip will need separate graphics. This is a pity, especially if it is a solution to the current crisis with insufficient availability of all hardware (and that buying a graphics card now is definitely not a pleasant experience). It would be better if, like the A9-9820 board, the iGPU was active with at least a small number of computing units, so that the APU could work without separate graphics. Especially when a PCIe switch has to be installed for this.
The AMD 4800S Desktop Kit should be bundled with the graphics card, saying that the Radeon RX 6600 card from TUL (ie PowerColor, but it may be an OEM card that does not carry the PowerColor brand) could be sold with it. However, the board itself is reportedly manufactured by MSI.
This combo could reportedly be on sale from the first quarter of 2022. It is not clear whether it will normally have to be sold in component stores, or whether it will only come on the market in finished computers with a box, source and disk.
