You lose Prolite, how much do you owe?
Sustained won't be anything close to that. Boost steps are temp driven and aggressively drop frequency in steps as temps rise. This is on GPU and now on CPU's as Zen is very temp sensitive. I follow the PC stuff closely so don't want to derail this too much but happy to go into any detail that's relevant.
We'll learn pretty fast what is sustained frequency.
I have more questions on the speeds because of this snippet from the DF Article --
Introducing boost for PlayStation 5
It's really important to clarify the PlayStation 5's use of variable frequencies. It's called 'boost' but it should not be compared with similarly named technologies found in smartphones, or even PC components like CPUs and GPUs. There, peak performance is tied directly to thermal headroom, so in higher temperature environments, gaming frame-rates can be lower - sometimes a lot lower. This is entirely at odds with expectations from a console, where we expect all machines to deliver the exact same performance. To be abundantly clear from the outset, PlayStation 5 is not boosting clocks in this way. According to Sony, all PS5 consoles process the same workloads with the same performance level in any environment, no matter what the ambient temperature may be.
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."
An internal monitor analyses workloads on both CPU and GPU and adjusts frequencies to match. While it's true that every piece of silicon has slightly different temperature and power characteristics, the monitor bases its determinations on the behaviour of what Cerny calls a 'model SoC' (system on chip) - a standard reference point for every PlayStation 5 that will be produced.

How? This isn't a open PC...
You'll have enough dev kits out in the wild that info like this will envitably leak.
Though probably true, we need to wait until we see the cooling solution. Cerny made a point of it being impressive, and he expects the GPU to stay at or around that speed.

But how slow will the CPU be when GPU is that fast? Doubtful to be able to have both maxed out at same time.
Let me stumble around blindly for a bit to have a look see. I know the page is supposed to be here, but I remember some mutterings from @Rys about having to revise something -- https://forum.beyond3d.com/help/subscribe-and-donate/
Variable frequencies up to 2.2ghz ? Has Cerny lost his mind ?
Memory Bandwidth is meh.
Ok then, this is a $399 machine. Better be for them.
