Radeon R600 is the codename for ATI Technologies' unannounced next generation Direct3D 10 graphics processing unit.
[edit] Rumors about Radeon R600
[edit] Launch date
[edit] Process
- The R600 is estimated to be a large GPU made with a rumored 500+ million transistor count. The PCB is also to be the thickest of all current VGA boards. Production is expected to be based on an 80 nm process with ATI having 65 nm/55 nm clearly in sight. [2]
[edit] Similar architectures
[edit] Architectural highlights
- Core working frequency ranging at 700 MHz to 800 MHz. [3]
- 64 unified shader pipelines (complex 4-way SIMD units [3]), 32 TMUs, and 16 ROPs.
- 512 bit "HyperScaled" external memory controller.
- 1024 bit internal bi-directional Ring Bus. [3]
- The R600 will feature support the GDDR4 memory interface with a 512 bit bus and 1024 MB RAM running higher than the X1950XTX's memory clock speeds of 1.0 GHz (2.0 GHz effective).
- Bandwidth range from 115.2 GB/s (using 1.0ns GDDR3 at 1800 MHz) to 140.8 GB/s (using 0.9ns GDDR4 at 2200 MHz). [4]
- Up to 2 GB GDDR4 on board. [4]
- 12 layer PCB design. [4]
- The Rage Theater chip was replaced with the newer digital Rage Theatre 200 chip. [4]
- The use of native CrossFire and will overtake the X1950 Pro as the most powerful card capable of Crossfire without a Master Card or an external Y-shaped dongle to connect the two cards.
[edit] Compatibility
- Designed "from the ground up" for Windows Vista and DirectX 10, according to sources at ATI. However it will still have support for DirectX 9 and OpenGL, as well as Windows XP.
[edit] Interface support
[edit] Power consumption
- Power consumption range from 130W to 300W. This increase in power consumption will make for higher-wattage Power Supply Units (to the 1 kW-1.2 kW range) and/or the addition of internal, secondary PSUs solely for powering the GPUs. [5]
[edit] Availability
- R600 is now being re-designed for make the PCB shorter and making it for better cooling, and to comply to the new PCI-SIG graphics spec of delivering 225/300W power for high-end graphics cards and providing a new 2x4 pin connector for additional power on top of the current 6-pin connector. [6]
- The first batch of R600 is being shipped to game developers and special customers which is clocked lower. [7]
[edit] Comparisons with main competitors
[edit] Miscellaneous
- R600 is the heaviest graphic card ever. [4]
[edit] Upcoming models
- There will be R680 and R700 coming up the near future as stated at a report listed below:

R680 will use the same cooler (as the R600) as well and still be able to work at over 1 GHz. This PCB is also the base for R700, but from what we are hearing, R700 will be a monster of a different kind. |
