The rabbit in the pan goes crazy and screams for pepper…

The PS5 has apparently decided to set new standards not only graphically, but also thermally.

Instead of ray tracing, there were traces of soot, and the term “next-gen [...]


Scale or fail: The long story of the overclocked Easter bunnie

High memory temperatures on many RDNA4 cards and what exactly is behind them – Cause research and background information

As I was also surprised by the high memory temperatures on many (but not all) of the RDNA4 cards I have tested so far and have received various inquiries from readers, this was the trigger for me to take a closer look at the problem.
