Not all the chips on a wafer turn out well, some of them turn out to be partially defective, allowing you to create new ranges of the same product at a lower price. But, in consoles where the specifications are fixed in all the models that partially defective chips appear on the wafer, or that do not give the expected performance in the quality tests, it causes them to have to be completely discarded.
A few weeks ago there were references to a new AMD CPU, which is called AMD 4700S, a nomenclature that is surprising for two reasons. The first is not having the term Ryzen in the name and the second is due to the fact that it derives from the APU or SoC used in the Xbox Series. Specifically, the Xbox Series X, which AMD has decided to sell as its AMD 4700 Desktop Kit in order to take advantage of the SoCs discarded in the manufacture of Microsoft’s console.
But, is the processor as is of the Microsoft console or has it suffered cuts? Rather the latter, so do not expect to be able to mount an Xbox Series X with this processor.
AMD 4700S, Xbox Series X APU becomes PC CPU
AMD has given an outlet to the APUs or SoCs of the Xbox Series X. So they have been sold on a board with all the elements integrated in the form of the AMD 4700S Desktop Kit. Which means that AMD sells in the same set the CPU 4700S, the board on which it is mounted and the RAM. Which is 16 GB of GDDR6 memory, which indicates that we are facing the Xbox Series X APU. All this soldered to the board, so it is a fully integrated system that we cannot update.
But why do we call the AMD 4700S CPU? Well, for the fact that Xbox Series X ‘powerful RDNA 2-based integrated GPU has been disabled, so therefore we are facing a CPU and not an APU as it lacks the GPU. Disabling the integrated GPU has allowed the 8-core Zen 2 CPU can reach 4 GHz.
The other difference with respect to the console is the chipset or Southbridge to which the AMD 4700S is connected, obviously it is not the Xbox one, but the AMD A77E Fusion Controller Hub, eWhich gives the AMD 4700S of 16 PCI Express lanes required to connect a graphics card, 2 SATA ports and interface 1 Gbps Ethernet. We also cannot forget the USB controller built into the internal IO Hub of CPUs based on AMD’s Zen architectures.
Certainly a curious way for AMD to capitalize on the Xbox Series X APUs that Microsoft cannot take advantage of for its console.
