PS5 GDC Reveal and PS5 specs/performance Digital Foundry Video analysis : 3.5 Ghz 8 core Zen 2 CPU along with 10.3 TF RDNA 2 RT capable and 16GB GDDR6 RAM and also super crazy fast 5.5 GB/Second S

The two things I find interesting are Memory Bandwidth differences for the Vram between XsX and Ps5 and the ps5's boost behaviour.

XSX has 10GB of Vram at 560GB/s and 6GB at 336GB/s vs Ps5's all 16GB at 448GB/s. It will be interesting to see how games perform as more and more Vram gets used cause in theory, if a game needs more than 10GB of Vram, the ps5 might be a bit of an advantage depending on the situation.

The boost aspect is also kind of interesting:

It almost sounds like if a game is on full tilt using all 8 cores at 3.5ghz and gpu at 2.23ghz, the ps5 might down clock slightly to meet it's power targets.

"What happens when the processor does hit its power limit and components down-clock? In his presentation, Mark Cerny freely admits that CPU and GPU won't always be running at 3.5GHz and 2.23GHz respectively."

"When that worst case game arrives, it will run at a lower clock speed. But not too much lower, to reduce power by 10 per cent it only takes a couple of percent reduction in frequency, so I'd expect any downclocking to be pretty minor," he explains. "All things considered, the change to a variable frequency approach will show significant gains for PlayStation gamers."

"So how does boost work in this case? Put simply, the PlayStation 5 is given a set power budget tied to the thermal limits of the cooling assembly. "It's a completely different paradigm," says Cerny. "Rather than running at constant frequency and letting the power vary based on the workload, we run at essentially constant power and let the frequency vary based on the workload.""

"Rather than look at the actual temperature of the silicon die, we look at the activities that the GPU and CPU are performing and set the frequencies on that basis - which makes everything deterministic and repeatable," Cerny explains in his presentation. "While we're at it, we also use AMD's SmartShift technology and send any unused power from the CPU to the GPU so it can squeeze out a few more pixels."
