R600 to feature 700 to 800MHz clock for the GPU
- Complex 12-layer PCB monster
- 512-bit memory controller
- Each memory chip has its own 32-bit wide physical connection to the chip's bi-directional bus of 1024-Bit RingBus memory interface.
- Memory bandwidth 115GB/s to 140.1GB/s (GDDR4 at 1.1GHz - 2.2GHz in DDR) (8800GTX only =’s 86GB/s)
- The R600 board is FAT. The PCB will be shorter than 8800GTX's in every variant & can be compared to X1950XT and 7900GTX.
- R600 will be the heaviest board that will hit the market in history.
- Monstrous all copper cooler, longer-than-the-PCB quad-heat pipe.
- The cooler actually enhances the structural integrity of the PCB, so you should be aware that R600 will bring some interesting things to the table.
- Why is it important that a cooler is so big? Well, it needs to dissipate heat from practically every element of the board: GPU chip, memory chips and the power regulation unit.
- Two versions of the board: #1 called Pele w/ 1GB to 2GB of GDDR4 memory, and UFO w/ 1GB to 2GB of GDDR3 memory.
- Newer digital Rage Theatre 200 to replace the aging original Rage Theatre chip.
- R600 will offer video-in and video-out functions, VIVO, HD in and out connectors (Built in All-in-Wonder???)
- R600 = 80nm @ 200 to 220 Watts – should consume less power then Geforce 8800GTX.
- R600 features new dual-bridge connector for Crossfire capability.
- Expect this baby to be in stores during Q1'07, or around January 30th.
- ATI's R600 features 64 Shader 4-way SIMD units. This is a very different and complex approach compared to Nvidia's relatively simple scalar Shader units.
- Since R600 SIMD Shader can calculate the result of four scalar units, it yields with scalar performance of 256 units
- R600 should feature at least five times more eDRAM than Xbox 360 has.
80nm
64 Shader pipelines (Vec4+Scalar) = yields with scalar performance of 256 units
720+ million transistor
32 TMU's
32 ROPs
128 Shader Operations per Cycle
800MHz Core
102.4 billion shader ops/sec
512GFLOPs for the shaders
2 Billion triangles/sec
25.6 Gpixels/Gtexels/sec
512-bit 1GB to 2GB 2.0GHz GDDR3 & 4 Memory
140+ GB/sec Bandwidth (at 2.0 GHz)
1024-Bit Ring Bus (ALSO?)
WGF2.0 Unified Shader
Better sell those 8800's while they're still worth something, this beast will be arriving end of January/February

I'll wait for the benchmarks, then we'll talk. Btw, nVIDIA is launching 9 more SKUs in Q1.
