AMD Kabini, based on the new Jaguar Cores, is aimed at the ultrabook-alternative segment. Specifically the A4-5000 and A6-5200 are the quad-core parts at 15W and 25W TDP that will compete against Ivy Bridge and Haswell based Ultrabooks and ‘pro-sumer’ tablets in 2013 and 2014. We’re expecting clock-for-clock performance with the quad-core Kabini platforms on par with (dual core) Ivy Bridge Ultrabook platforms but with a slightly better power utilization figure, especially when when the GPU is under load. However, remember that the A4-5000 is running at 1.5Ghz with no Turbo boost. Real-world performance on that part won’t be up to what we see on Ultrabooks that can sustain 2.4Ghz. Will the A6-5200 be better positioned with 2.0Ghz clock?
Test results on an A4-5000 at Anandtech confirm a good but not Ivy Bridge Ultrabook-beating performance level. There’s no great advance in gaming capability for the ultrathin segment and CPU levels are simply on-par with Ivy Bridge. Efficiency is slightly improved on a task-by-task basis meaning that pricing will be the key to success for AMD Kabini, especially as BayTrail and Haswell reach the market in Q3/Q4.
Extrapolating the test figures out to an A6-5200 with HD8400 graphics and a 2.0Ghz clock with 25W TDP you can see some potential for ultrathin designs that match Ivy Bridge and HD4000 but is that enough as Haswell launches and those ‘old’ Ultrabooks start to drop in price dramatically? We don’t think so.
