The Zen 2 processor AMD 4700S which powers the Xbox Series X console has been spotted in a mini-ITX gaming PC at Tmall in China. The 4700S processor was first spotted online last week as part of the AMD 4700S Desktop Kit. You may be able to pick up one very soon but without the RDNA 2 graphics.
When the AMD 4700S was first spotted, it raised many questions regarding it. The chip does not carry the Ryzen branding, suggesting that it might be a custom processor that AMD developed for one of its clients. Stranger still, the processor is available for purchase as part of the AMD 4700S Desktop Kit.
The AMD 4700S is an octa-core Zen 2 processor with simultaneous multithreading (SMT). The processor has a base clock of 3.6 GHz and an all-core boost clock of 4 GHz. The Tmall merchant listed the AMD 4700S with 12MB of L3 cache, although we saw the chip with 8MB in a previous Geekbench 5 submission.
The AMD 4700S is outfitted with 16GB of GDDR6 memory, which is the same amount of memory in the Xbox Series X. It appears that AMD is salvaging defective dies that don’t meet the requirements for the Xbox Series X and reselling them as the AMD 4700S.
The AMD 4700S could be a result of a defective die with a faulty iGPU, similar to Intel’s graphics-less F-series chips. AMD could also have simply disabled the iGPU inside the AMD 4700S. The only image of the mini-ITX system’s interior revealed a motherboard that looks like the same size as the Xbox Series X. There are no memory slots, and we can see some of the GDDR6 chips that surround the processor.
AMD has reworked the motherboard for PC usage, as we can see by the addition of capacitors, passive heatsinks, power connectors, and connectivity ports. Since the AMD 4700S lacks an iGPU, AMD added a PCIe 3.0 x16 expansion slot for a discrete graphics card.
In general, the AMD 4700S lags behind the Ryzen 7 4750G (Renoir) and Core i7-9700 (Coffee Lake) in single-core workloads. The AMD 4700S did outperform the Core i7-9700 in multi-core workloads. However, it still placed behind the Ryzen 7 4750G.
It remains to be seen whether AMD is selling the Zen 2 AMD 4700S found in the Xbox Series X to retail customers or just OEMs.
