The firm bases its claim on a set of "industry standard" benchmarks which it said means that competing - that is to say Intel chips - are outperformed to the tune of 17 per cent.
AMD started shipping the Barton 3000+ today with 640K of cache memory - it also claims that's a first.
Companies shipping the chip today include NEC and Packard Bell, and AMD said other manufacturers will ship machines based on its latest product "soon".
The Barton 3000+ costs $588 when you buy them in 1,000 batches, said AMD.
AMD prices are here.
The next rev of Barton for the desktop is the 3200+, which the latest roadmaps indicate won't be out until late summer this year, unless AMD changes its mind.
There's reviews popping up all over the place, we'll write a separate story about that later. µ
