    The variable clocks (CPU moreso) and memory BW are the most disappointing.

    I swear Sony did 2.23ghz just to make me lose.

    Alright how about everyone donate?

    Does 2.23 count if it's boost clocks?

    I can't believe they cranked the speed up so high.

    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.

    I have several questions...

    We'll see what this is in practice though.

    GPU clocks above 2.2GHz.

    Pay up.

    $100K to B3D.
    Are we going to stick with this?

    But how slow will the CPU be when GPU is that fast? Doubtful to be able to have both maxed out at same time.

    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.
