[edit] Overview
The Chrome S25 was launched alongside the Chrome S27 on 3 Nov 2005 as part of the Chrome 20 series(detailed specifications are there as well). It utilises the same core as its 'bigger brother', the Chrome S27 which is manufactured on Fujitsu's 90nm process but is clocked lower on both its memory(down 300 mHz to 400 mHz) and GPU clockspeed(down 100 mHz to 600 mHz). It core likely consist of GPUs which failed to make the grade for the Chrome S27 and thus have been clocked lower. It is targeted at the low end of the graphics card desktop market and at low power laptops with its Chromotion™ Video Engine as its main selling point. This is essentially its video and DVD playback capabilities. Another main selling point is its very low power consumption of as low as 9W and thus heat output even with comparison to similarly targeted graphics cards from Nvidia and ATI making it suited for HTPC and low power notebook setups. Possibly due to such targeting, it only has shader model 2 capabilities and not shader model 3 ones.
The Chrome S25 comes in a 128mb and 256mb DDR2 version only unlike the Chrome S27 which is able to utilise DDR3. It also has the AcceleRAM™ feature which allows the graphics card to cache data to the system memory if more is needed. Unlike the Chrome S27 however, The Chrome S25 has no MultiChrome (Multi GPU) capability.
[edit] Miscellanea
Although S3 graphics does not sell this card themselves, they can be found under the Xiai brand in Japan and the Axper brand in China. Both these cards have their GPU clockspeed and memory clocked 100 mHz higher than the default specification giving a 700 mHz memory and 500 mHz GPU clockspeed
