AMD silicon is at the heart of the Xbox X, Xbox Series S and PlayStation 5 series, which means the red team is working hard to produce as much RDNA 2 and Zen 2 silicon as they can to meet demand. In doing so, you are likely to be accumulating a lot of broken chips, those with a few (or a few million) transistors out of the norm. Chips that don't finish cutting can end up in this desktop kit you have before: the AMD 4700S.
The AMD 4700S is almost the complete package for a PC (using Videocardz). Under the included refrigerator is a CPU with AMD Zen 2 technology, an eight-core chip, which puts it in line with the latest consoles and some Ryzen CPUs. Next to it is the revealing sign of the origin of the console of this chip: it includes 8 GB or 16 GB of GDDR6 memory.
Modern consoles use shared memory pools, i.e. GDDR6 currently, something you won’t find on any gaming PC. While GDDR6 offers a lot of bandwidth for GPUs, DDR4 is much better suited to the overall memory task of the system thanks to its low latencies. So there’s no real reason for AMD to produce a desktop kit with GDDR6 memory unless it already has the chips around.
From what I can tell, look at the pictures of Disclosuzen on Twitter (via TechPowerUp), the memory should be located at the bottom of the motherboard, under the extended rear heatsink. This does not provide the memory with the optimal cooling solution, although this machine is not able to outperform the PC.
With the memory probably at the bottom of the PCB, it looks like it's part of the PS5 SoC. Twitter rogame leaker also detects matching traces between the 4700S and the PS5, suggesting that this chip could have been destined once for Sony's console. The AMD-Sony chip-making agreement may have some stipulation that AMD may use or purchase chips that Sony does not use, but we cannot say for sure.
I'm pretty sure it's a PS5 APU. Just check the PCB trace memory. https://t.co/QvZhX4wBMc pic.twitter.com/fS7iQfYfTGJune 28, 2021
Note the lack of a Ryzen brand here, technically it’s not a Ryzen product despite sharing the Zen 2 architecture with AMD’s Ryzen 3000 chips. The AMD 4700S page features the painted circle logo that it had assumed was the Ryzen logo, but may be representative of Zen architecture. Either way, AMD is clearly trying to avoid the Ryzen brand here.
To build the whole set, the CPU and memory are paired with a fairly basic motherboard. It has two SATA ports, a 1 Gbps LAN port, eight USB ports, basic audio output from I / O and a couple of headers for additional USB connections. There is no M.2 NVMe port, however, and only a PCIe 2.0 x4 slot for a single GPU.
However, you must provide one. This kit does not include any form of GPU. If it was a chip taken from a console, it would include an RDNA 2 GPU running with a countable computing unit count (56, 36 or 20, depending on the console), but here it is completely disabled, it's a say, a graphics card needs some description.
It's a shame, an APU with console graphics would be immense.
There are only a few graphics cards listed with official compatibility with the 4700S: AMD's RX 500 series and Nvidia's GT 710, 730 and GTX 1050, 1050 Ti and 1060. bandwidth is to blame for GPU restrictions. You can read the system specifications in their installation and warranty brochure (PDF warning).
Not that you would want to build a gaming PC anyway on this board. We suspect that their performance would not be up to par with the latest gaming machines.
On graphics cards, wafers that don’t quite get the note are usually the reasons we end up with cards like the GeForce RTX 3060 Ti, built with a slightly less capable version of the GA104 GPU than otherwise would go into a GeForce RTX 3070. Microsoft will use the same tactic with chips that don’t shrink the Xbox Series X, instead of finding a home in the Xbox Series S. But if you’ve ever wondered what happens to all the disused chips and non-functional parts without If you use it on the ground console, the AMD 4700S should give you an idea of where they end up.
Don't waste it, you don't want to.
