Mobility Radeon X800

[...]The Mobility Radeon X800 also quite frequently offers performance delta's to the Mobility Radeon 9800 in the order of 50%-80%, which again is a fairly impressive increase for the platform in only a few months. The margin to the desktop Radeon X800 PRO is as we would have expected given that they only differ in their clock speeds, and while the X800 PRO isn't the very highest end enthusiast product it is still fairly high up the scale.

While we discussed the aforementioned Mobility Radeon 9700 as the previous enthusiast product, one thing to note is that the Mobility Radeon X800's are only going to be in much larger chassis mobile solutions and be in a much smaller niche. Whilst the thermal conditions of Mobility Radeon 9700 saw it end up in a wide variety of solutions, right down to fairly thin notebooks, heat generated from the Mobility Radeon X800, and from the high performance CPUs that are also going to need to be supplied alongside such parts, are going to ensure that these will be in big chassis and, more often than not, need fairly impressive cooling for a mobile solution.

x800 mobile hat nur 8 pipes während die x800 pro 12 hat

die 9800er hat lei 4 pipelines und basiert mehr oder weniger aufn r350er core

M28, fundamentally, is very similar to M18 as they are both derived from basically the same core parts. Where M18 is derived from ATI’s R420 core, M28 is derived from R423 – both of these cores are architecturally, and performance configuration wise, the same but R420 is built for AGP graphics whilst R423 is built for PCI Express. Where the configurations differ, primarily, is in the number of pixel quads that are enabled - while R420 and R423 have 4 pixel quads (16 pipelines), M18 utilised 2 pixel quads (8 pipelines) whilst M28 has 3 pixel quads enabled.
