I hear you. But that 2.23 Ghz GPU in the PS5 is crazy high, and will run hot. I won't lie. I'm a bit concerned. Can't wait to see the actual design of the PS5 to see if it will alleviate my concerns.
To reach that clock figure they had to change the way they looked at thermal latency (AFAIK) and have knocked it out of the park with a solution going from reactive to proactive cooling. If the amount of heat being generated is mostly just a by-product of work done + ambient, then cooling should be a breeze for the ps5 - pun intended :)

I asked for a 1st class ticket on the Playstation train but no one put me there either... may I join your train? :messenger_tears_of_joy:
Even Phil Spencer is hyped, get in sir 🤣🤣

The cooling conrol fascinates me, I read that AMD smartshift has 2ms granularity, but what is response of clocks ? You would think they would sync the control of both....

And even if you can predict a hot set of work load, can you change the clocks and voltages in time or will teh change effect the next job in the queue most likely ? Fascinating...

Its got to be quick and many times a frame to be useful for sure. I know it will work Sony will have poured engineering into it and qualified it to death with expected console numbers, I am just interested.

One thing I'd like out of next generation: apps that don't require a system update to work even if they go online.

The one annoying thing about using a console as a media device as they tend to require all system updates be immediately installed in order to use them. I get why you need to do that for online games, but I feel like they could get away with marking media apps as not having the requirement, or at least do it on an update by update basis (have it so the update indicates what types of apps need to force an update before they can be used.)

The famitsu report about the sega rumour was supposed to be in a magazine right?, as some subscribers were likely to get it early there was a possibility that the info could be leaked by early week right?

My guess is there is a multiplexor(lookup table of bit pattern to clock/voltage) aggregating GPU instruction sets as they enter the L2 cache, with the multiplexor having a queue that changes the clock/voltage when the pattern actually executes.

The hard part in that scenario would be whether to lose clock performance and generate more excess heat by being overly conservative on power draw, or being less conservative and potentially breach the power limit. Maybe that was what Cerny meant by 'essentially using constant power'.

How smartshift factors in might also be surprising, as we could potentially have bursts where the GPU is working at full width and then needing to down clock, but if the CPU has spare power from working below maximum the excess could be shifted, allowing the GPU to do the full 2.23Ghz with all 36CUs working.

Completely agree. The cooling technology is going to be great to see.

It has to be job related wher maybe CPU and GPU are being pushed a certain way, a set of circumstances that is known to be a heat generator.

Maybe I read it wrong and that 2ms is the time in a given state not volts / clocks reaction time, its getting late lol

Holy.... 27!? Why dude? That's not good for your health. That hyped can't sleep? Are you planning to stay awake til the reveal? Lol.

On a side note, I remember back in the day when I went long without sleeping I'd get uncontrollably giggly as a side effect.
Get to bed now and stay there for two days, we need you fresh for the big event in the week.

I miss the gif hype. Previous to the PS4 GAF made our most famous actor its mascot and Cerny… I was about to put a Cerny gif but searching “Cerny gif” in google images returns some inappropriate gifs
this late at night. :messenger_hushed:
What ever you do with inappropriate images of Mark Cerny in your own home is totally up to you, i will not judge.

Its the Phil spenser ones i draw the line at.

I hear you back.

The theory is sound - but the implementation.... If Sony got it right that cooling system and balance to power usage will be just right.

But if they made a misstep - too little power and the processors can’t fill up the clock tick with useful work, too much it gets too hot. Running too close to the chassis TDP will risk down clocking if a work load spike crops up.

If they got the balance wrong they’re carrying that to PS5 pro at least.

But I think the system they’ve implemented is deterministic - they should’ve been able to foresee any issues and account for them.

It may all just come down to quality control at manufacturing!

We can only fit so much in the notification box and it was meant more for the thread in general. Also, my apologies as well since it seems you got caught in the crossfire. No warnings have been taken against your account when it comes to post deletions.

Thanks for the kind response! Apologies on my part actually. I should've just contacted one of you guys if I had an issue, rather than broadcast it... not my usual fare.

👍 👍

How the heck do you leave anything more than a 'like 👍' on someone post that you mighty like/agree with/find funny/or just intriguing ??
That is the only option I get is 'like 👍', am I missing something or need to upgrade my membership... or something?

I have options on my iPad, but if I’m on my PC I can only do thumbs up.
