Gaming Performance with Battlefield 2 and Black & White 2

The gaming performance of the Core Duo is not as cut and dry with respect to the Pentium M as some of the other performance tests, mainly because the vast majority of games are still single threaded.  Here, we have to rely on the FP/SSE optimizations in games to overwhelm the increase in cache latency to give the Core Duo any sort of advantage over the Pentium M. 

Battlefield 2

Under Battlefield 2, we're able to see a small 3% performance advantage over the Pentium M. However, compared to the Athlon 64 X2, the Core Duo does not stand a chance. 

At higher resolutions, the performance advantage decreases in this particular game.  What performance at lower resolutions does tell us is that in this type of AI/physics load, the Athlon 64 X2 is a much better performer than the Core Duo, which does have some importance for performance in future games.

    Yup... as I posted above... the rumor is that Yonah was designed for 2.5GHz (maybe even 2.6GHz or so) and can easily be overclocked to those speeds but is being launched at the speeds it is for exactly what you say... to fit in a certain power envelope.

    We'll, that's definitely a logical argument, but I'd say only marginally relavent to this discussion. If a laptop with X% better power consumption comes out, does it really matter in the end where those X% came from. I can see the validity in saying that maybe some of those optimizations are on the board and thus the CPU shouldn't be given all the credit, but lower consumption is lower consumption. But that's all hypothetical. The reality is that even without optimizations, the Pentium M would have enjoyed lower power consumption just by moving to the 65nm proccess, as would any proccessor. that's where most of that 30% came from. I'd venture to say that the board design provides 1 or 2 % max, and definitely within the margin of error.

    Um, i got confused there a bit. I'm basically saying that the new "Core Duo" derives the majority of it's efficiency not from any architectual changes (although they do help a lot), but from the move to 65nm. When AMD makes that jump to (and if Intel hasn't already gone to 45nm) then you'll see AMD pull ahead in power consumption on all 65nm parts, if not performance as well. Remember, aside from the on-die controller, this new architecture is very similar to what AMD is doing. Like the author said, if they wanted to copy something, they should at least copy the serial bus!

    All one know that Dothan is 90nm.But it is very cool. hot == Intel's 90nm? No!
    The CPU's architecture of low power consume is key. We must understand that IC design is very complex, many advanced tech are applied to keep CPU cool, include the CPU's architecture(such as micro-ops fusion).

    Yonah is better? It seems to be like its a pretty even match clock-for-clock but if you consider that X2s max out at 2.4GHz (currently) and Yonah will launch in around 15 days at 2.13GHz (the FX-60 is supposed to launch around the same time, so the X2 max clock may hit 2.6GHz when Yonah arrives) then it is clearly inferior in the performance department. Granted, the power consumption is quite a bit better but I'd hardly say that the CPU is better, just better suited for low-power applications.

    Yonah(2GHz/L2 2M) is better than AthonX2(2GHz/L2 2M) in the many cases.
    Everyone also believe that Yonah is able to reach the very high frequency.
    In the past, We also known that PM can be overclocked better than A64. The PM's best record of Super Pi is much fast than A64/FX.

    Yonah Yonah Yonah... Nah it was hype as I suspected... these procesors are vitually identical to AMD's old A-64's.. AMD supposed to get signifigant bumps w. DDR2/3 and PCIe onboard plus I read about some technology AMD and IBM made to increase performance by a whopping 40%!!

    AMD has nothing to fear other than in power arena when longer pipe Conroe comes and even then that advantage may very well disappear.


  • IntelUser2000 - Tuesday, December 20, 2005 - link

    The 40% advantage is TRANSISTOR performance. Even then, its 40% advantage when no straining is included at all. AMD has strained silicon in their current process. Which means real advantage is FAR less than 40%.

    PCIe onboard is not a speed advantage. It´s more a tactic move towards the the computer on a chip solution.

    AMD is keen on ondie memory controller and in some years PCIe aswell due to the fact they suck at chipsets. Sure nVidia is making some good ones now. But it´s always been Intels extra strong point.

    PCIe would also gives less traces on the motherboard that gives lower cost. But your CPU will break the 1300pin mark atleast and will be unable to scale in any way. Like AMDs backwards setting with DDR. When some new PCIe or more PCIe lanes comes out. You would need a new socket.

    However personally I´m in favour of it. I just think AMDs ondie solutions is the wrong way. On package seems alot better and more flexible. Until we have an even more stagnant development cycle for external parts.

    DDR2 advantage? I wouldn't count on it. The latency on DDR2 still sucks compared to DDR. I wouldn't be so quick to scoff - Yonah performs as well as the X2 while consuming only a fraction of the electrical power.

    I don't see why people thought Yonah was going to be some sort of X2 destroyer. Its execution core has far fewer units than K8 and it lacks an on-die memory controler. The fact that it can match an X2 with slimmer cores makes it all the more impressive. The only hype was in your mind.

    The AMD/IBM technology is not in processors that we can benchmark today -- they have yet to bring this process to mass manufacturing.
