PowerVR Rogue GPU To Crank Out 350m "Real Polygons", 5GPx Fill Rate

Semiconductor giant ST-Ericsson spilt the beans on the next generation of PowerVR graphics processing unit, the Series6, codenamed Rogue which is going to be used in the Nova A9600, its top end system on chip, which will sample at the end of 2011.

In a press release issued yesterday, ST-Ericsson says that the A9600 will bring a more than 20-fold improvement in graphics performance compared to the U8500, which uses a single core ARM-based Mali 400 GPU clocked at 400MHz.

This corresponds to the comments made the day before by David Harold, the director of PR at Imagination Technologies, who told us that the Series6 architecture would bring a 20x improvement compared to the Series5 SGX.

The Rogue GPU will deliver more than 210GFlops (no details as if single or double precision), deliver 350 million real polygons per second and more than five gigapixels per second visible fill rate, which translates into 13 gigapixels of effective fill rate.

This is because, unlike other rival technologies, PowerVR only processes pixels that will be displayed, leaving out hidden ones.

Rogue will be compatible with existing APIs and soon-to-come ones like the OpenGL ES codenamed Haiti. The Nova A9600, which is the first official SoC to come with Rogue, will be manufactured using a 28nm geometry.

Imagination Technologies did confirm that the performance comparisons are for the same power envelope which makes it more than likely that Rogue's figures are for multicore parts.
