The Radeon HD 2600 and 2400
Below we have some pictures of ATI's upcoming Radeon HD 2600 and 2400 Pro and XT cards. If you're counting, including the Radeon XD 2900 XT, that makes 5 different Radeon so far...
First, let's talk about the Radeon HD 2600 XT and Pro. As we've already mentioned, the GPU at the heart of the Radeon HD 2600 family of cards is derived from the R600 and has essentially the same feature set. The Radeon HD 2600, however, has only 120 stream processing units, 8 texture units and 4 ROPs. Radeon HD 2600 cards are outfitted with a 128-bit memory interface and they'll be equipped with 256MB of DDR2, GDDR3, or GDDR4 memory. Memory clock speeds with range from 400MHz to 1.1GHz and GPU clocks will be between 600MHz and 800MHz depending on the model. As you can see, all of the cards are adorned with single-slot coolers.
Another noteworthy aspect to the Radeon HD 2600 series of GPUs is that they are manufactured on TSMC's 65nm process node. The GPU itself is comprised of roughly 390 million transistors and cards will consume approximately 45 watts, hence the lack of supplemental power connectors on the boards pictured here.
The Radeon HD 2400 family of cards is also comes in XT and Pro flavors. The Radeon HD 2400 GPU is made up of approximately 180 million transistors and it too is manufactured on TSMC's 65nm node. The GPU features 40 stream processing units with 4 texture units and 4 render back-ends, and depending on the model it will be clocked between 525MHz and 700MHz. All Radeon HD 2400 series cards also have single-slot coolers, and some will be passively cooled. Products in the Radeon HD 2400 family also feature a 64-bit memory interface and will be configured with between 128MB to 256MB of GDDR3 or DDR2 RAM clocked between 400MHz and 800MHz. Power consumption will be in the 25w range.
Both the Radeon HD 2400 and HD 2600 cards can output audio via HDMI using the same special adaptor mentioned earlier. 2400 series cards, however, will be equipped with only a single dual-link DVI output in conjunction with standard VGA and HD video outputs. The HD 2600 will have a similar dual, dual-link DVI plus HD video output configuration to the Radeon HD 2900 XT.
