Test System And Benchmarks
In an effort to best demonstrate multiple configurations, we first tested our system at stock frequencies using 800 MHz memory at 8-8-8-24-2T timings. Those are the same settings used in February's Llano-based overclocking story. Then, we overclocked Corsair's Vengeance kit to 933 MHz (the architecture's highest official data rate) using 9-9-9-24-29-1T timings, but kept stock CPU and GPU speeds.
We're also including a standard overclock using the same 933 MHz memory setting, changing only the CPU and GPU multipliers, but not the reference clock. This gives us 3.6 GHz processing cores and a 960 MHz GPU.
Finally, we include the highest memory overclock, a 117 MHz reference clock, 3627 MHz CPU cores, a 936 MHz GPU, and 1092 MHz (2184 MT/s DDR3) memory at 10-10-10-27-35-2T.
We're ultimately interested in how our all-out overclock compares to a discrete Radeon HD 6670 DDR3. So, we installed it in the overclocked system and disengaged its on-die GPU.

This is pretty cool, this addresses most of the questions I would have about gaming with a LLano part. But it seems Trinity is right around the corner so I would still have reservations about recommending it. Except for the fact I just saw one of these quads for $90 at the egg, which does make a compelling case for folks on a tight budget.Reply
Interesting read. Can't wait to see how much of an improvement the desktop Trinity APU brings seeing Llano is better than what I imagine it would beReply
Don is the best!Reply
Hi Don, you have wrote great article!Reply
I have just one question - do you try to overclock the memory controller as well, because its not mentioned in the article? Thanks in advance
Llano is great, but i am waiting for the die-shrink to reduce power and heat.Reply
Wife's pentium intel g620 and amd 7750 on budget board and 8 gb budget ram .....only pulls 150 watts max !!!!!!!!lcost less and performs much better. Apu is a epic idea, alas still useless maybe trinity will save the day. Until then the hype and misleading performance promises will still make them money.Reply
On page 2 there is a reference to hwbot.com, which seemingly doesn't exist anymore.Reply
Thanks for catching that, fixed to hwbot.org!

Makes you wonder how old the article is that a dead domain link made it into the text :)
"So, we installed it (6670) in the overclocked system and disengaged its on-die GPU."Reply
I don't get why all these major sites don't test the dual graphics nature of the asymetrical xfire that Llano supports? Marry that APU with a 6570 or 6670 for maximum performance, that's the whole point of the Llano experience imo! I have a Llano notebook and am so hungry for info on other's experiments and results with the APU+DGPU.
Excuse the noob question, but if you had say 2 x 4gb sticks rather than 2 x 2 and you put on a corsair H40 contained water cooler for example could you get much better OC performance? This is looking like a viable option.Reply
