AMD Ryzen 4000 'Renoir' APU Runs Crysis Without Any Cooling Solution:

Fritzchens Fritz over at Twitter, who has provided several close-up die shots of CPUs and GPUs in the past, has managed to run a Ryzen 4000 APU without any cooling solution attached to it. Using the Ryzen 3 4300U, a four core and four-thread processor that's clocked at a base clock of 2.7 GHz base and 3.7 GHz boost clock, the chip was tested under an intense scenario where it was provided no active or even passive cooling.

[...] The CPU doesn't even feature an IHS to carry off the heat from the die which makes this little test even more brutal but the chip didn't even break a sweat. This was mostly achieved using the Renoir Mobile Tuning tool that helps set the original temperature limit down to 90C.

[...] But it's not the Cinebench R15 score that makes this little test interesting but rather a full run of the Crysis benchmark. The APU also houses five enhanced Vega compute units which equates to a total of 320 stream processors running at 1400 MHz. Like the CPU, the GPU also has to manage thermal limits by reducing clock speeds but despite no cooling solution, the chip was able to run a complete loop of the Crysis benchmark without a hiccup.

    Four cores, four threads, 2700/3700MHz? Fuck, it'd better run cool. The ten year old Phenom II x6 that just got the boot as my gaming rig was six cores, six threads, and 3200/3600MHz and it never got above 50C with non-impressive air cooling.

    Wow indeed. Do you really need that much computing power to play minesweeper? (grin)

      Butbutbut how can you play that lame old 2D minesweeper. You need 3D animations and loading screens after every move, and of course 4K support so you can really see it all blow up.

        Mea culpa. Does Dwarf Fortress plays OK, tho'?

          I was looking into Dwarf Fortress performance yesterday, and I found this:

          https://dwarffortresswiki.org/index.php/DF2014:System_requirements [dwarffortresswiki.org]

          As Dwarf Fortress's bottlenecks are mostly due to cache misses, it has been speculated on the DF forums that "a CPU with a positively giant L3/L4 cache (and I mean > 256 mb or GTFO)" would improve DF performance, as would using faster RAM with smaller transfer times.

          AMD is rumored to be stacking a DRAM L4 cache on the I/O die with Zen 4 or Zen 5. At least 1 GB would be likely, and Dwarf Fortress typically uses less than that, so that might be the perfect new CPU to play Dwarf Fortress on (coming in 2 to 4 years, possibly).

          Pffft, like I'd play that bloated monstrosity. There's gotta be at least 400K lines of code in that thing.
