CHIPMAKER Intel will dump Imagination's PowerVR graphics in favour of its own integrated GPU for the Bay Trail Atom chip, according to leaked slides.

Intel has been using PowerVR graphics cores on its Atom chips for a number of iterations but according to a leaked roadmap the firm will move to its own GPU with its Bay Trail Atom chip. The firm's Bay Trail chip will succeed Clover Trail and is expected to appear in 2014 sporting four cores and a clock speed of 2.1GHz.

According to Mobile Geeks' leaked roadmap slides the chip will be fabbed on Intel's 22nm process node that it uses to churn out its present Ivy Bridge chips, and will support low-profile DDR3-1067 memory. However the firm's biggest change will be the move to its HD Graphics core, which is likely to be a derivative of its Intel HD Graphics 4000 core that's found on its Ivy Bridge processors and supports Microsoft's Directx 11.

Intel still has to bring Clover Trail to market next year and the chip is expected to power a range of low-end Windows 8 laptops and tablets. However Bay Trail could be the chip that really pits the Atom against competition from ARM vendors, with gains in power efficiency thanks to the move to 22nm and tighter integration with more parts of the chip designed in-house.

Intel has previously said that its Atom roadmap will iterate faster than its Core processors and it needs to if Chipzilla is to have any hope of fighting off ARM designs. However it seems that by 2014 the company will have an all-Intel design and a very mature process node with which to churn out cheap X86 chips. µ
