AMD showed off a new Acer tablet with a 5W Ontario APU at a press event in Singapore:
Maybe it's because it's early on a Monday morning, but beyond revealing the existence of the chip, the automated translation of the PC Watch piece doesn't seem very clear to me. Luckily, the folks at Softpedia seem to have figured it out. They say AMD managed to get its dual-core C-50 APU into a 5W power envelope by limiting the "number of frequencies and terminations" supported by the memory controller and by limiting I/O.
The result, apparently, is a 5W version of the AMD C-50 that still has two cores and, judging by this screenshot PC Watch grabbed, a 1GHz clock speed.
