AMD Jaguar vs Llano (K10) at same clocks

Sat May 25, 2013 10:06 am

Hi folks. I wrote a blogpost (with test data) about Jaguar vs Llano at same clocks (1.5GHz). I tested Llano myself while I sourced Jaguar data from TR, Anandtech as well as PCPer.

Thoughts welcome :)

Don't forget that Llano has dual-channel. The jaguar core may be starved in some workloads, so even though the execution potential is there, it also depends on the way memory is accessed.

Yeah that is a definite possibility. Perhaps sometime I will hobble the 3500M to a single channel and do the comparisons again :D

Thanks for posting this information.

If you're looking to expand the test items, what about some benchmarks where Jaguar has hardware support for instructions that Llano doesn't? AES-NI, AVX, etc. Some OpenCL applications might be worth comparing, too.
Wind, Sand and Stars.

Well to be honest not sure I will do more tests anytime soon. It was just something I quickly put together to get a ballpark estimate :)

Looking at it from the perspective of a "small, dual-issue [low-power]" core, this is very impressive.

Looking at it from the perspective of "new hardware from AMD", particularly with respect to this processor's inclusion in the new game consoles, these numbers are a little disappointing -- although not at all unexpected. Would have liked to have seen Kaveri in the new consoles. ┐(´∀`)┌

The consoles are already $500, do you want them to be $700?

Hehe, no, and there's the power consumption angle too. Llano's old Stars cores are absolute dogs in terms of perf/watt.

Llano/Trinity/Richland also have up to a 100w power envelope to Kabinis 25w max, so there's that too.

(as I see was kinda mentioned already :) )
