8 cores for chess
All 8 worked for me. I can run 8 chess games simultaneously. And there are not 4 at a higher level than the others. Chess is integer not float. Still, wasn't that impressive as compared to the best Intel stuff...but I did not pay for the best Intel stuff either.
Most of the big talk about Bulldozer was way before launch. Everyone who wanted to look, could look at benchmarks. I honestly don't think the lawyers had a good case. But 12m probably does not hurt them too bad either. But then there are 49 more states. People generally don't buy CPUs for floating point. Float is better done by the GPU. That is likely why they had fewer float units.
I used my computer to play literally millions of games of chess for Stockfish development. Most of that independent testing of ideas, but some on their Framework.
I own AMD stock...so I am disclosing that. But everything I said was factual. http://tests.stockfishchess.org/users 549300 games run there. But like I said, most of the games I ran were not on the Framework.
