[NH] AMD Kaveri - graphics performance on par with Radeon HD 7750 - Page 3

I'm having a hard time keeping the names straight right now...
Current: Llano
Next: ??? (Can't remember the name...)
Next-next: Kaveri?
Is that correct?

Llano: 400 SP's - same transistor count as desktop 6570
Trinity: ??? Who knows. Supposed to be 30% faster than Llano.
Kaveri: 384 GCN SP's, same as 7750. Which is roughly the same performance as a 6770 (800 VLIW5 SP's). So.. that would be double from Llano.


I'd expect higher memory bandwidth than Llano, definitely. Perhaps AMD will add 512MB of GDDR5 onboard for the APU. One can dream biggrin.gif

Thank you!

A quick Google showed that Trinity might release during the summer of this year. Maybe I'll snag one of those in a laptop, although I'm having a hard time coming up with reasons my little Acer isn't doing it's job well...

We will see...

Kaveri will have 512 SP's like the 7750. 1 GCN Compute unit = 64 SP's. And if it's going to have 8 Compute units then it will have 512 SP's thumb.gif

if Bulldozer packed an iGPU that was on par with say a Juniper it would have been an amazing product for extreme budget game builds

Agreed. In terms of laptops, the AMD APU's are probably the best choice for the average consumer, in my opinion.

There are not many people out there that will even utilize i3 performance in a laptop. Plus, having decent graphics makes APUs a very well-rounded platform.

But an APU with even 80% of the graphics performance of a desktop 7750 will be awesome. BF3 will finally be playable with 60fps on an IGP!

i find lower latency rates on the memory help more than speed. even if we have1866@c9 then ity'll be awesome !

gotta love the speculation from a forum wizzard
