I'm not talking about the usual just-so-frequent incompatibilities, crashes, or other obvious problems, and not even about the various hacked overclocking tools. But something a bit more in the shadow:
- Llano has quite reduced DIV/IDIV performance (I'm really not the the guy recommending to undo errata fixes, but considering all the recent guarding around speculative execution.. maybe there is a chance?)
- Bulldozer has crippled x87 performance (there are no public errata regarding the feature, so this might be all free real estate?)
- Possibly every architecture before Ryzen could hit the TDP ceiling before even reaching the maximum frequencies (unclear whether this couldn't just be specific to some motherboards and/or workload though)
- Steamroller CPUs may get throttled when their iGPU is in use (which seems a pretty common scenario for every "low budget gamer", but of course you would have to first be CPU-limited to even hope for an improvement). Alternatively if a modded BIOS isn't available, editing p-states and disabling APM should be enough.
- funnily enough, this didn't seem to happen at least on the oldest bobcat apus, and it was somewhat holding down GPU performance
And I could swear I knew more, but time was hard on my memory.
