Just for comparison, let's take a look at what NVIDIA is currently offering as well. We don't expect to see a higher performance mobile part until AMD can get the power consumption of its higher end hardware down (likely with a process shrink). This is very likely due to the high power draw and low performance per watt we see with AMD's 80nm R600. While 24 standard and XT versions will exist in the mobile space, there are currently no plans for a high end mobile part. The exception here is the Mobility Radeon HD 2300, which is a DX9 part based on R5xx hardware. While we aren't certain, our best guess is that mobile parts named similarly to desktop parts will have the same internal configuration of SPs, texture units, and render back ends. It's harder to pin down all the specs of the mobile parts, as all the clock speeds (and sometimes bus width) can change depending on the TDP envelope a notebook maker is working with. Let's take a look at a break down of what we do know we'll be getting: AMD R6xx Hardware This is unconfirmed at present, so take it with a grain of salt. There is currently no add-in retail hardware planned that tops the HD 2900 XT, but we are hearing rumors that faster parts may be available through OEMs only.
On the desktop, in addition to the HD 2900 XT, we will see the Radeon HD 2400 Pro and XT in the "value" segment, with the HD 2600 Pro and XT providing good mainstream-to-midrange gaming performance. Performance on all other R6xx parts won't be available until "late June", but we can still talk about what these parts will be when they finally make it to market. While all of this hardware is being made public, we've only got one piece of hardware to bring to the table today: the R600 based Radeon HD 2900 XT. The announcement today includes a top-to-bottom lineup of DX10 class hardware including four mobile parts (with one additional DX9 mobile part sharing the HD 2000 series naming) and five desktop parts.
