Lol

Stumbled on this, curiously clicked it, this entire thread is hilarious in hindsight
lol haha. This is my favorite post. From ProElite/DukeBlueBalls/Tommy Fucking Fisher
This is AMD SmartShift:

Notice how the power ratios between GPU and CPU can be extreme either side?

The ends are the CPU downclocked by 50%, and the GPU upclocked by 20%, or the CPU upclocked by 20% and the GPU downclocked by 40%.

I expect the PS5 to spend most of its time at ~3.4GHz, and ~2ghz. The memory bandwidth suggests that operating range. 448GB/s is too little for ~10TF narrow and fast design.

Just a reminder that PS5 GPU at 2.23ghz has to push 53% more rasterization per GB/s than the X.

I think there are edge cases in some games where 2.23ghz can be brought to full use. I.e. moments with lots of alpha transparency effects (fog, windows).
  • GPU downclocked by 40%!!!!
  • CPU downclocked by 50%
  • 9 tflops.
  • Memory Bandwidth bottlenecks.

What a post!

I'm not proud to admit this but I fell for this BS. There was so much negativity at the time that I thought some of it was true. Fortunately that didn't happen.
Sony's terrible marketing and Cerny going silent didnt help matters. I legit thought the PS5 was a disaster. This was almost 8 months before RDNA 2.0 was announced and AMD's high clock and perf/watt gains were announced. We were working on half of the information.
