AMD quietly confirms Radeon 6300M, 6500M notebook video

AMD Radeon 6000M made official in low-key intro

Without a formal launch, AMD has quietly confirmed the existence of the Radeon HD 6000M for notebooks. Dropping the Mobility tag, the 6300M and 6500M are the direct sequels to the mid-range Mobility Radeon 5400 and 5600 chips; both share the same improved architecture as their desktop equivalents. Both should be faster for the same amount of power and support the same visual features, including more natural morphological antialiasing and hardware tessellation to automatically increase or reduce object detail.

The 6300M is designed for budget notebooks and has the same 80 stream (visual effects processing) cores, eight texture units and other features of the outgoing 5400 series, including core clock speeds that range from 550MHz to 750MHz. AMD claims a lower polygon rate of 187.5 million polygons per second versus 550 million, but a much higher textured pixel fill rate of six gigapixels per second should help compensate for the earlier design's 4.4. It also boasts a faster 900MHz memory clock.

Moving to the 6500M provides a similar parallel to the Mobility Radeon 5650, sharing the same 400 stream cores and 20 texture units, but doesn't make any noticeable sacrifices in rendering performance. The 6500M's best model tops out at the same 650MHz as its predecessor, but a higher 500MHz base speed and faster 900MHz memory help push it up to a faster 500 to 600 million polygons per second.

The graphics chipsets aren't officially attached to shipping hardware, but a handful of computers from Acer, Gateway and Lenovo are already known to be shipping with 6550M and 6570M chipsets early next year. Other notebooks using current processors may arrive sooner.
