The RV610LE will be known to the world as Radeon HD 2400 Pro, and will support 720p HD playback. If you want 1080p HD playback, you have to get a faster performing part. In addition, the HD2400Pro will be paired with DDR2 memory only, the very same chips many of enthusiasts use as their system memory - DDR2-800 or PC2-6400, 800 MHz memory. The reason for the 720p limitation is very simple - this chip heads against G86-303 chip with 64-bit memory interface, the 8300 series. It goes without saying that the RV610LE is a 64-bit chip as well.
The second in line is RV610Pro chip, branded Radeon HD 2400 XT. This pup is paired with GDDR3 memory and is the first chip able to playback Full HD video (1920x1080), thanks to the fact that this is a fully-fledged RV610 GPU, no ultra-cheap-64-bit-only-PCB. RV630 Pro is an interesting one. Formally named Radeon HD 2600 Pro, it sports the very same DDR2 memory used on HD 2400Pro and GeForce 8500GTs we have, but there are some memory controller differences that will be revealed to you as soon as we get permission to put the pictures online.
The RV630XT - the Radeon HD 2600 XT - is nearly identical to the Pro version when it comes to the GPU, but this board is a monster when it comes to memory support, just like its predecessor, the X1600XT. However, this is the only product in the whole launch day line-up that has support for both GDDR-3 and GDDR-4 memory types. Both GDDR-3 and GDDR-4 memory will end up clocked to heavens high, meaning the excellent 8600GTS will have a fearsome competitor.
The R600 512MB is the grand finale. R600 is HD 2900 XT, as our Wily already disclosed. This board packs 512MB of GDDR-3 memory from Samsung, and offers same or a little better performance than 8800GTX, at a price point of 8800GTS. R600 GPU supports two independent video streams, so even a dual-link DVI can be done, even though we doubt this was high on AMD's priority list. This product is nine months late, and a refresh is around the corner, unless AMD continues to execute as ATi did.
The R600 1GB is very interesting. Originally, we heard about this product as a GDDR-4 only, and it is supposed to launch on Computex. We heard more details, and now you need to order at least 100 cards to get it, it will be available in limited quantities only. We expect that ATi will refrain from introduction until a dual-die product from nV shows up, so that AMD can offer CrossFire version with 2GB of video memory in total, for the same price as Nvidia's 1.5GB. Then again, in the war of video memory numbers, AMD is now losing to Nvidia flat-out.
Damn! No 1GB card at launch? :( :( :(
That means R600 512MB will be competing with 768MB 8800GTX. I don't know what they are thinking, but don't people still think higher VRAM is always better? R600 might not need 1GB to unleash all its muscles, because it has been proven that the performance delta of 256MB X1950XT vs. 512MB X1950XTX is marginal even at very high resolutions because of the memory subsystem design. I hope they won't make this too expensive, because I thought the 1GB version will come out at US$500 range. :oo:
