Sony PlayStation 5 Rocks AMD Zen 2 And RDNA 2 Muscle, 5.5GB/Sec SSD, And 16GB GDDR6

Sony was the first out of the gate to reveal details on its next-generation game console: the PlayStation 5. Sony first told us about the PlayStation 5 in April 2019 and confirmed that the console would be powered by an AMD Zen 2-based processor, Navi GPU, and that it would have an ultra-fast SSD for storage. It was later revealed that the DualShock 5 controller would support haptic feedback. 

Today, however, Sony is giving us a true "deep dive" into the architecture of the PlayStation 5, much like how Microsoft has already done with its competing Xbox Series X. Not surprisingly, specs are very similar to that of the Xbox Series X with an 8-core Zen 2 CPU that runs at up to 3.5GHz.

However, the PlayStation 5 is using a less powerful RDNA 2 GPU (operating at 2.23GHz), which features just 36 CUs compared to 52 CUs for the Xbox Series X. As a result, maximum compute performance comes in at 10.28 TFLOPs versus 12 TFLOPs for the Xbox Series S. A total of 16GB GDDR6 memory is installed using a 256-bit interface, bringing total memory bandwidth to 448GB/sec.

In another comparison point against the Xbox Series X, the PlayStation 5 will features an 825GB PCIe 4.0 SSD (1TB for the Xbox Series X) that is rated at up to 5.5GB/sec and features a custom 12-channel controller. One area where the PlayStation 5 will outdo the Xbox Series X, however, is with storage expansion. The Xbox Series X uses a proprietary 1TB expansion card that is made by Seagate.

The PlayStation 5, on the other hand, will be able to accept off-the-shelf M.2 SSDs. But the SSD will have to meet certain specifications, including PCIe 4.0 compliance and read performance of at least 5.5GB/sec. Sony says that it will provide a full list of compatible SSDs when the PlayStation 5 launches.

When it comes to performance, Sony's Mark Cerny explained that while the PlayStation 4 was only capable of loading 1GB of data in about 20 second using its HDD, the PlayStation 5 can load 5GB of data in just one second. Cerny said that the inclusion of an SSD was the most frequently asked "upgrade" that developers wanted for the PlayStation 5.
