Only 20% faster than Llano D: Maybe they are only targeting notebooks with Trinity

 

[waffleironhead]

Isnt llano on par with phenom2 stars core minus the L3 cache? A 20% performance bump would be nice imo. 20% cpu boost with a 30% gpu boost would be nice. Hopefully they have 32nm evolved enough to get better efficiency and thermals out of it.

 

[Olikan]

not sure. it said to be 20% better at media workloads.

still, a 2 module trinity is supposed to run at 2.5ghz, and 1 module at 3.3ghz.
and a llano quadcore is 2.6ghz with better ipc... black magic?

still what is that samu? and vec?

Trinity uses the Piledriver core which is supposed to have something like 10-15% better IPC than Bulldozer

If you read carefully, it says 'up to 20% faster'. D:

I wonder how much more 'throughput'?

 

[Arkadrel]

20% faster CPU, 30% faster GPU.... doesnt sound so bad.

Its not like Llano is slow currently, atleast gpu wise, its over twice Sandy Bridges IGP. The question is how much faster is Intel's Ivy Bridge IGP gonna be (Im assumeing thats what trinity will be benched against).

CPU wise... I really hope there are signs of Piledriver saveing bulldozer.

That chart indicates 10-15% better performance/watt - so we don't know which way it'll go (higher perf, or less watts).

Well, that makes sense then. I was thinking a a top end Quad Trinity would be up at 3.3GHz or better. Too bad, so sad - it might have made a nice low end desktop system. Looks like they are aiming at Notebooks.

 

[podspi]

20% over Llano isn't going to blow the doors off of anything, but if GPGPU computing really takes off (media encoding where the quality doesn't suck, for example) and battery life is there, this could (again) make a potent budget media/gaming notebook.

I'd hope that ST performance increases more than 20% Llano tob-bin, given BD is a high-speed design and 3rd gen turbo. And while a K10 @ 2.5ghz isn't slow, it also isn't fast...

It is going to be very interesting watching Trinity compete with Ivy Bridge, especially in ULV configurations. Very excited for the possibilities w/ IB on the ultraportable end...

CPU wise... I really hope there are signs of Piledriver saveing bulldozer.

Last I read, BDII (w/Piledriver) isn't out till 2H12. So BDI w/B3 stepping will be up against Ivy Bridge, which probably means its relative performance to Intel's desktop chips will stay about the same (not good).

If GF can deliver 10% more on clock speed and Piledriver get at least a 10% IPC boost - then AMD would be back in the game. But this is just a wing and a prayer ATM. The are three major problems that need to be addressed with BD's implementation (effective decode issue width, cache latency and slow int operations) - apparently these aren't very easy fixes, otherwise Piledriver would produce a very competitive part.

My fear is, how can you put together such a massive CPU with a GPU big enough to actually make a chip good enough/fast enough for a low price? And bulldozer has proven to be very power INNEFICIENT.

If a 4.2GHz "8 core" cant compete with Intel, how is a reduced power nerfed 2.5GHz version going to compete? GPUs are good, but again, how can they put anything in there that will compete with the midrange dedicated cards (woulda had a better chance if the CPU werent so bloated/inneficient)?

Would you really want to skimp 150$ to get a slower machine with half the battery life? Im hoping trinity is a big win, but with figures in on bulldozer it doesnt sound like its a good chance. Especially with the prospect of mobile 28nm GPUs...current gen Intel/Optimus laptops already have great performance and battery life...lower cost lower power next gen GPUs will make an even more killer combo.

Would love to see a good 5hr midrange gaming laptop for $500

Trinity won't have the 8MB L3, that space saved will be where the GPU goes.

 

[sm625]

I pity the foo who actually thinks trinity will offer 20% more single threaded performance. I cant wait to see how they spin notebooks as not caring about IPC.

If it can deliver incredible performance/watt, it will definitely have a place, even if the raw performance isn't stellar. I'm doubting AMDs ability to deliver on this, but at this point my expectations may be so low that I'll end up pleasantly surprised.

 

[alyarb]

Llano is already a 32nm device and represents the highest performance per watt to date for AMD. Unless the cacheless Piledriver is a total departure what we saw from desktop Bulldozer, I imagine power will go up a little and performance will go down a little.

 

[gmaster456]

Well Its not like llano is terrible. Especially for sub $100. And in the mobile space llano is actually doing quite well. 20% better performance for trinity would be very welcome.

 

[frostedflakes]

Trinity production is expected to be prepared by November, with volume production beginning in January. If all goes well, Trinity should arrive before Intel's Ivy Bridge.

Had no idea these were coming out so soon. Will be interesting to see what kind of performance improvements (if any) Piledriver actually has.

20% faster than Llano would be pretty impressive. Remember that they'll still be using the same 32nm process, so 20% for only an architectural change isn't bad at all, IIRC that's inline with the kind of performance increases Intel delivers at every Tock when they introduce a new architecture. Certainly nothing to scoff at.

Really doubt it will be anywhere close to 20% faster for most tasks, though. Maybe for the handful of tasks that perform very well on Bulldozer, but not across the board. But we'll see.

I'm hoping Trinity brings cost down for AMD notebooks, because I don't see any reason to believe that it will bring meaningfully better performance or power consumption than Llano. Llano brought K10.5 down from 45nm to 32nm. Desktop Bulldozer is already based on 32nm and has similar power consumption as K10.5. I'm a big AMD fan, but it requires a large leap in logic to believe that another stepping is going to make enough of a difference to matter.

Then again Arrandale and Pine View had extremely little gains over their predecessors, and Intel didn't really suffer.

That's because everyone's been looking at peak power of BD running at full clock speed. It is much more likely that the new trinity core will not be the same clock speed as the desktop BD part. Also, remember that until Llano the previous AMD mobile CPUs had worse power characteristics using similar CPU architecture. And compared to the C2D the pre llano cores were uncompetitive as well on the same node scale.

Remember that rule of thumb for power dissipation goes up quadratically with clock frequency. So if you drop peak frequency by half you power goes down 4 times. To get 1/2 the power dissipation of 4ghz it is possible to do so by dropping the clock by 25%. Which should still leave trinity quite a bit higher clocked and thus faster than Llano.

@cotak13, from post #3 Trinity will be running around 2.5GHz - which should give it good thermals for notebooks.
