Maybe that's why the document was taken down. What a blunder. Robert Myers.

This is the starting link: http://sites.amd.com/us/atwork/promo/events/Pages/analyst-day.aspx Next is "Executive Presentations and Webcast Archive", which might work: http://phx.corporate-ir.net/phoenix.zhtml?c=74093&p=irol-analystday And of course all the links on that page are totally non-copyable. Idiots. I changed my opinion of Bulldozer, not two cores with shared FPU. Kind of one core with two separate integer pipes, and code threads. Actually a lot depends on how wide the fetch and decode is. For x86 fetch and decode is a large chunk of die space that is mostly idle. With that assumption you are back to this performing the same as a dual core, at 2/3rds the die space. Which would be a pretty overwhelming advantage. Unlike hypethreading this will never cost you performance. And for single thread benchmarks you turn off the second thread, same as Intel. ;) Brett

Which would be a pretty overwhelming advantage. Here is a Athlon64 die plot: http://www.amd.com/us-en/assets/content_type/DigitalMedia/Ath64_die_marked_P.jpg Biggest block is "Fetch Scan Align Microcode", second smallest is the execution units. Instruction Cache shared, Bus unit shared, Load/Store unit I am not sure. So Bulldozer has 2 Execution units, 2 L1 data caches, likely two Load/Store, and a doubled FPU that is shared. So indeed 2/3rds the die space of two full cores. If L2 size stays the same the total die size and production cost is ~20% greater for twice the performance. Overwhelming advantage. Brett

(Except from some of the guys > who were at AMD at the time.) But it feels good nevertheless. Freudian typo? It would have been better if I had stayed at either Intel or AMD to see MCMT through. But MCMT never took hold at Intel. Apparently it did at AMD. While I never took root at either company. Not for lack of trying. But neither was a friendly place. |
