Our colleagues over at MadboxPC.com have managed to score some pictures of ATI's upcoming low-end HD 3400 and HD 3600 series graphics cards.
The slowest and thus the cheapest will be branded Radeon HD 3450, and according to the specs over at MadboxPC.com, it will be a low profile card with integrated Displayport. Both Radeon HD 3450 and HD 3470 will be based on the same 55nm RV620 chip with PCI-Express 2.0 support and 64-bit memory interface.
The slower Radeon HD 3450 will work at 525MHz for the core and 400MHz (800MHz effective) for 256MB of GDDR2 memory. The faster one HD 3470 will come clocked around 600MHz and it will use either 256 or 512MB of GDDR3 memory clocked at 500MHz (1000MHz effective). According to that same article, price for the HD 3450 will be around $50 USD, while HD 3470 will be sold for $60 USD.
The faster Radeon HD 3650 is based on 55nm RV635 GPU that works at 800MHz for XT and 600MHz for PRO version, which is strange since ATI has abandoned the XT and PRO branding. It will also use either 256MB or 512MB of GDDR3 memory working at 1000MHz (2000MHz effective), but unlike the low-end HD 3400 series this one will use a 128-bit memory interface. According to MadboxPC.com the suggested price for this card will be around $100 USD.
All of them will have DirectX 10.1 support and will come with ATI's praised UVD. ATI might have a low-end winner with these cards, but we hoped that low-end will no longer be using the 64-bit memory interface; but then again, $50 USD for a good low-profile HTPC card sounds good.
