The GPU, called the Mali-450, is designed to help manufacturers build tablets that cost less than market-leading products like Apple's iPad, which starts at $399, but provide good enough graphics performance to keep most users satisfied.

With touchscreens and high-definition video now fairly mainstream, the GPUs in tablets and smartphones account for a bigger share of the cost, and take up more space on the CPU on which they're integrated.

Some manufacturers want cheaper parts, however, that offer reasonable graphics performance and occupy less die space. That's where the 450 is targeted, said Ian Smythe, director of marketing in ARM's Media Processing Division.

The new GPU is offered with up to eight cores and offers double the performance of its predecessor, the Mali-400, which has up to four cores, Smythe said. The Mali-450 is expected to appear in tablets in the first half of next year, he said.

Tablet makers are demanding a wide range of price and performance characteristics, so ARM is essentially bifurcating its GPU road map. It will offer the Mali-T600 family for higher-end devices, and the Mali-400 family, including the 450, for the low end.
