ATI Radeon 7500 Mobility Announced
10:41 AM | Michael Eilers | Comment on this story

Following their announcement of the Radeon 8500 and 7500 chipsets earlier this month, ATI Technologies has announced the future availability of the Radeon Mobility 7500 chip. As the name implies, this is a chip aimed at portable computers, with specialized features designed to reduce power drain and enhance 2D video features.

As with the 7500 graphics card, there are no clear plans for this Mobility 7500 chip set to come to the Mac OS; Apple did not use the previous Radeon Mobility chip set in their portables either, much to the disappointment of would-be Powerbook gamers. But now Apple will have a dilemma when choosing the next chipset for a "refresh" of their Powerbook and iBook lines -- Radeon Mobility, Mobility 7500 or NVIDIA's GeForce 2GO chipset (based on the GeForce 2 MX series).

From the amazing feature set of the 7500, it seems gamers should be hoping and praying that the Mobility 7500 is the one that makes the cut. Here are some details from the press release:

ATI Technologies Inc. (TSE:ATY, NASDAQ:ATYT), the world's number one notebook graphics vendor, today unveiled the MOBILITY™ RADEON™ 7500, ATI's next-generation mobile graphics processor and the most powerful, feature-rich mobile solution in the world.

The MOBILITY RADEON 7500 delivers almost twice the performance of its nearest competitor on a range of industry standard benchmark tests, according to a study by Inquest Market Research . MOBILITY RADEON 7500 is also the first mobile GPU (graphics processor unit) to support 128-bit DDR (double data rate) memory - double the current standard and, therefore, dramatically raising the bar for notebook 3D performance.

When operated in power-saving mode using ATI's ground-breaking POWERPLAY™ voltage and frequency scaling technology, the new chip consumes less than half a watt in a light usage scenario. ATI's unique POWERPLAY technology, which further refines ATI's industry-leading power management technology, produces the lowest power consumption levels in typical 2D, 3D and DVD (digital versatile disc) modes. For example, POWERPLAY extends DVD playback on battery power by up to 25 percent, enabling, for example, full playback of feature-length movies. POWERPLAY modulates clock speeds and voltage settings automatically when users switch between AC (alternating current) and battery operation, and includes the option of user-selectable voltage/frequency scaling, which allows for maximum-performance even when running off battery power.

Unlike most portable chipsets which trim off the Transform and Lighting capabilities (like the GeForce2Go) the Mobility 7500 includes the entire Radeon feature set, including Charisma Engine, Pixel Tapestry, Video Immersion and ATI's Hyper-Z technology. The clock speed of the CPU and RAM are not given, though the 7500 is supposed to be clocked over 60% faster than the previous Radeon chipset.

Only time will tell as to which graphics hardware Apple will include in their next line of portables, but as ATI hardware has been the standard since Apple's first Powerbooks that seems a likely bet. Here's hoping that the Radeon Mobility 7500 is Apple's choice for their 2002 refresh of the Powerbook series.
