AMD 4700S Review: PC Kit Based on PlayStation 5 SoC

A few weeks after AMD quietly announced its unique 4700S kit, the first review and real-world photos of this peculiar product, based on a custom SoC designed for the PlayStation 5, have emerged online.

First, let's recap what the AMD 4700S actually is. It's an APU based on a system-on-chip custom-made for the Sony PlayStation 5 console. The chip features 8 cores and 16 threads with AMD Zen 2 architecture, but its RDNA 2 graphics are disabled. For RAM, the device utilizes GDDR6 video memory (specifically, soldered Hynix chips in this instance), which is quite unusual for a desktop platform.

The 4700S APU connects to the AMD A77E Fusion Controller Hub (FCH). Interestingly, this is the same chipset used in the AMD A9-9820 system, which itself was based on the Xbox One APU codenamed 'Durango.' This is precisely why, during its early announcement, tech media speculated that the AMD 4700S system was based on an Xbox Series X or Series S SoC.

Key specs for this new product include 8GB of 14 GHz GDDR6 video memory (which is non-expandable) and a maximum APU core clock of 3200 MHz.

CPU-Z can't accurately display AMD 4700S specifications.

By the way, thanks to its GDDR6 memory, the AMD 4700S boasts an impressive 144 GB of bandwidth. However, given its modest capacity, it's difficult to count this as a significant advantage:

However, it's worth noting that 144 GB/s of bandwidth is an unattainable result for both AMD and Intel desktop platforms.

Unfortunately, as we mentioned earlier, the APU's graphics are disabled. So, for in-game testing, our colleagues atBodnara used an AMD Radeon RX 550 graphics card. In this setup, the AMD 4700S went up against a Core i7-11700 with integrated Intel graphics. However, keep in mind that the discrete graphics adapter in the AMD 4700 system is limited to PCI Express 2.0 x4. This means the Radeon RX 550's performance is bottlenecked by the PCI Express speed, making it pointless to install anything faster than the aforementioned graphics card.

Testing the AMD 4700S in 3D Mark, League of Legends, Overwatch, and PUBG:

Overall, the AMD 4700S + Radeon RX 550 proved slightly faster than the Core i7-11700 processor. But as the graphs above likely showed, the AMD 4700S clearly wasn't designed for gamers. This system is better suited for office use or, at best, embedded applications.
