Bulldozer Performance Expectations

When Intel announced its first Core microarchitecture CPUs, we saw a number of charts that looked like this:

Intel used performance-per-watt to compare the efficiency of its new architecture to its predecessors. AMD is unveiling Bulldozer's performance target in a similar way, by looking at performance-per-watt:

In the client desktop/notebook space, Bulldozer will have around 1.3x better performance per watt than Barcelona. AMD also indicated that Bulldozer will deliver as much as 1.5 - 2.0x better performance per watt in the server and HPC space when compared to Barcelona.



Better efficiency is obviously important, but absolute performance can't be ignored which is why AMD tagged Bulldozer with the line: "designed to be the highest performing single and multi-threaded compute core in history."

Bulldozer will have to go up against Intel's Nehalem core, which to recap is a dramatically evolved member of the Core architecture.

    What the heck are RDDR and UDDR? My only guess is the U might stand for the UMA design, but I don't know if that would be preferred for the server or workstation. Reply

    RDDR = Registered DDR
    UDDR = Unbuffered DDR

    Take care,

    Ok, what is OoO? I couldn't find it with a search on Google. Reply

    OoO is "out-of-order" referring to OoOE, "out-of-order-execution"

    This is the best future roadmap article I have ever read. I am actually excited. No really. Reply

    I am an AMD fanboy, of 7 computers I have at home, only the 5 year old laptop has an Intel chip now. Dual cores are actually likely all I REALLY need. That said, I am sick of a bunch of hype and no new products. It's all blow and no show. I don't care about years down the road because it could all change between now and then.

    AMD/ATI could be a good thing too if they make good, polished drivers, 100% working for what was promised. How about throwing people a bone to make them switch, maybe even make some kick butt Linux drivers too.

    We were all on an AMD bus and nobody has been driving since the X2 chip. They taunted Intel and handed out huge bonuses, but forgot about any new development. I have to credit Intel, they kicked butt with Core 2, and seem to be doing more butt kicking going forward.

    I watched Hector on CNBC last night and he didn't look like he had a clue what was going on. Granted they weren't asking him details of any processors, but he was dodging basic business questions. Why do I have several hundred shares of AMD?

    Because those relatively cheap shares, compared to Intel's, might be worth hundreds of times more one day from that stuff you call blow. Blow = prospects in business terms.

    I would say the same thing as you did though at first. It's obvious AMD and ATi's pipeline dried up and unfortunately both consecutively. You can argue that the 2900XT is a good card, performs well, etc..etc.. but that doesn't explain why AMD offers crapware for main stream (where the real money is). As for AMD's CPU line up...well..you can only sell old for so long in the technology sector without taking a hit.

    .... dump ATi. The marriage made in hell. New products unable to meet schedule and with inferior performance, thus no way of rapidly recovering development costs by pricing for performance.

    Dave Orton sure did a neat sell-job on AMD, walking away with $$millions when AMD paid a 20% premium for a chronically non-performing company barely managing to eke out some tiny profits during the last couple of years. No wonder Mr. Orton was finally shown the door.

    What is the problem with AMD, did they not receive enough feedback that UVD is a "must have" on high end units. I don't want to have choose between good gaming performance and movie performance... I am paying a ridiculous premium already for hardware... the least they could do is make sure it has all the bells and whistles. Reply
