Doesn't look like the lack of L3 makes that much difference to me (except abby finereader), just turbo seems to fail to clock up even a tiny bit with multithreaded loads and never reaching anything close to the max even with single-threaded loads.
Yea you are right that L3 would have cost a lot for a little gain. Turbo seems to either be very limited or bugged.
Still poor excuse for using ddr3-1333 even on the desktop. Maybe though we'll see ddr3-1600 a bit more in notebooks now? Let's face it up to now there just wasn't much incentive to use faster memory in notebooks. Well intel didn't support it at all, not sure about AMD but it would have been totally pointless anyway. The (presumably pretty small) power draw disadvantage should be well worth the faster graphics you get from ddr3-1600 I think. Though I'm wondering why it only supports low-voltage ddr3-1333 and not the low-voltage ddr3-1600 version - but few notebooks use low-voltage dimms today.
I've seen these benches but there was no proof it was due to the L3 sharing. Even if it was though there are ways to solve this (could reserve portions of the L3 cache to either cpus or gpu for instance), in any case I expect sharing L3 between cpu and gpu is going to be inevitable for next gen, the advantages are just too big.and that classic shared memory architecture worked better.
sandy bridge has this little problem where the performance tanks if all CPU threads are fully loaded while amd keeps the GPU usable.
once again Intel is the high rev and high tech small gasoline engine, and AMD is the clunky turbo diesel that falls short on power, but is steady when hauling big loads and is quite advanced on its own too.
If we're talking gaming performance, I think the 4-core Llano is actually quite balanced to pair with a graphics system with a processing power equivalent to a downclocked desktop HD5750.
Of course you have to remember that multi GPU setups come with issues in some games and require profiles to perform well. Sometimes it simply doesn't benefit a particular game at all. That's why I tend to ignore Crossfire and SLI.
I tend to think that's about the best scaling you'll ever see though (and it's still 20% off that GTX460M btw).
Not even close there are plenty of HD5570 out there with, get this, DDR2 memory!
I don't really see any improvement in that area, the better prefetching should be specific to the cpu cores. For the gpu I think it won't make much of a difference, it'll just have slightly higher latency (likely as it's more complex) than redwood MC had.
Yes Brazos should be equally bandwidth limited. Strange though the cpu would get higher scores with gpu turned off, the GPU shouldn't need much bandwidth (when it's idle - of course running full tilt it might have a similar scheme to Llano giving gpu access higher priority).
Wow! I was ready to take bets there's going to be a 6570 inside Trinity!
