According to mobile marketing manager Ravi Gananathan, ATI tries to leverage its desktop technology into its mobile designs. Usually, the changes between the desktop and mobile designs revolve around optimizing performance and features while minimizing the laptop power consumption/heat dissipation requirements. The new ATI Rage Mobility 128 is just another example of this ATI tradition; the Rage Mobility 128 is basically the mobile version of the Rage 128 Pro, a chip just released 6 months ago. The Rage Mobility 128 will run with 105MHz core and 105MHz memory speeds.
Not just a repackaged Rage 128 Pro chip, the Rage Mobility 128 chip integrates many other mobile specific features required for notebook design (integrated TV encoder, dual CRT controllers with support for two independent digital displays, on-chip digital panel scaling, etc). RAGE Mobility 128's integrated TV-encoder is taken from ATI's RAGE Theatre chip - the one driving the TV on the Rage Fury Pro board. The Mobility 128 also has LVDS and TMDS interfaces for digital panel output support. Finally, the Mobility 128 also sports 8MB of SDRAM. The video memory is not on the die itself, but it is part of the packaging. The Rage Mobility 128 is priced at $55 in lots of 10,000.
All this looks impressive, but will the chip really be able to give gamers the performance needed for Quake 3 in a laptop? What about all the other factors besides speed that affect game play? Yes, there is more to game play than frames per second. ATI let our resident Quake 3 experts at FiringSquad give it a go on the Rage Mobility 128.
