AMD 4700S Processor Could be Repurposed Xbox Series X/S APU

[Uskompuf]

The AMD 4700S is a new processor being advertised by Chinese manufactures as a complete ITX compatible solution. The processor is soldered to a custom "Cardinal" motherboard produced by AMD which lacks memory slots and instead features 16 GB of GDDR6 memory located around the processor. These specifications seem to closely reflect those of the Xbox Series X APU. The 4700S is an 8-core 16-thread 7 nm Zen 2 CPU with 12 MB cache and a boost clock of 4.0 GHz which is actually higher than that of the Xbox Series X/S at 3.8 GHz and 3.6 GHz respectively. This higher boost clock is likely due to the exclusion of an integrated GPU which increases the power available for the processor.

The seller also provided benchmarks for the processor in various Cinebench configurations where it outperformed the Intel Core i7-9700 and performed just below the AMD Ryzen 7 4750G. The processor paired with an RX 550 GPU also outperformed the Intel Core i7-9750H paired with an RTX 2060 and 32 GB memory in Cinebench and x264/x265 video encoding. The seller has a picture of the Xbox Series X APU in their advertising material for the new processor lending weight to the theory that these are reused processors which failed qualification.

Its a shame they disabled the RDNA2 GPU and provided a low end RX 550 instead. I would rather AMD disable some of the units on the GPU that is not fit for purpose. The CPU + the RDNA2 GPU will make this a formidable APU.

I’d bet on that the series s/x chip is in this product only because the GPU side does not function properly - and not in a way where you can just disable a few CUs, as there is a lot of leeway on the consoles already for that.

Could make a neat project board, but I doubt it'll be easily available outside of China.

10 memory chips equals 16GB?

if i recall correcty they had deffirent types of chips on there (i may be wrong) (probably because GPU need more RAM bandwith then the CPU ?)

I could show you the math, but it only works in my head.

lets start with 1+1=3 and go from there!

10 memory chips equals 16GB?

(paraphrased from a reddit post)

For the left and right rows, they are K4Z80325BC-HC14, or 14Gbps 1GB ICs from Samsung
For the row in the middle, they are K4ZAF325BM-HC14, or 14Gbps 2GB ICs from Samsung

So, basically 1x4+1x4+2x4=16

As to why they did this, Xbox engineering reasons that i'm to dumb to understand.

1+1+1+1+1+1+1+1+2+2+2+2=16
Xbox logic:
1+1=2
1+1+1+1=2+2
2+2+2+2+2+2+2+2=16
Now all the same!

Yup. First 10 gigs will work at a higher bandwidth than the last 6. It’ll be interesting to see if that is problematic in desktop use, considering that the amount of badwidth to use is pretty high in all cases as it is not shared with the iGPU (because it’s disabled).

AMD 4700S Desktop APU Is Slightly Faster Than The Xbox Series X Chip, Features 16 GB GDDR6 Onboard Memory, 8 Cores & Up To 4.0 GHz Clocks

The AMD 4700S APU is a faster Xbox Series X chip which is being sold in China for gaming desktop PCs with 16 GB GDDR6 memory.

wccftech.com

"Listed over at T-Mall by a 3rd party seller, the AMD 4700S is being sold as a complete unit within a Mini-ITX Gaming PC. The retailer has listed pricing of 4599 - 5599 Chinese Yuan which converts to around $700-$800 US which is a pretty hefty price but it does make some sense considering specs of this PC include not just the chip but the PSU, the case, storage, and an external discrete graphics card.

Does this make sense as a little lan box?
