Thanks to TG Daily we can now talk about the very soon to be released ATI HD 4800 series of graphics cards with more details. One week ahead of its presumable release date, general specifications of the new cards have been revealed. All Radeon 4800 graphics will use the 55nm TSMC produced RV770 GPU, that include over 800 million transistors, 480 stream processors or shader units (96+384), 32 texture units, 16 ROPs, a 256-bit memory controller (512-bit for the Radeon 4870 X2) and native GDDR3/4/5 support as reported before. At first, AMD’s graphics division will launch three new cards - Radeon HD 4850, 4870 and 4870 X2:
- ATI Radeon HD 4850 - 650MHz/850MHz/1140MHz core/shader/memory clock speeds, 20.8 GTexel/s (32 TMU x 0.65 GHz) fill-rate, available in 256MB/512MB of GDDR3 memory or 512MB of GDDR5 memory clocked at 1.73GHz
- ATI Radeon HD 4870 - 850MHz/1050MHz/1940MHz core/shader/memory clock speeds, 27.2 GTexel/s (32 TMU x 0.85 GHz) fill-rate, available in 1GB GDDR5 version only
- ATI Radeon HD 4870 X2 - unknown core/shader clock speeds, available with 2048MB of GDDR5 memory clocked at 1730MHz
The 4850 256MB GDDR3 version will arrive as the successor of the 3850 256MB with a price in the sub-$200 range. The 4850 512MB GDDR3 should retail for $229, while the 4850 512MB GDDR5 will set you back about $249-269. The 1GB GDDR5 powered 4870 will retail between $329-349. The flagship Radeon HD 4870 X2 will ship later this year for $499.
