Level 505 has leaked benchmarks (thanks DailyTech) and specifications of AMD's upcoming ATI R600 graphics processor. The upcoming graphics processor is expected to launch in January 2007 with an expected revision arriving in March 2007:

64 4-Way SIMD Unified Shaders, 128 Shader Operations/Cycle
32 TMUs, 16 ROPs
512 bit Memory Controller, full 32 bit per chip connection
GDDR3 at 900 MHz clock speed (January)
GDDR4 at 1.1 GHz clock speed (March, revised edition)
Total bandwidth 115 GB/s on GDDR3
Total bandwidth 140 GB/s on GDDR4
Consumer memory support 1024 MB
DX10 full compatibility with draft DX10.1 vendor-specific cap removal (unified programming)
32FP internal processing
Hardware support for GPU clustering (any 2^n number, not limited to Dual or Quad-GPU)
Hardware DVI-HDCP support (High-Bandwidth Digital Content Protection)
Hardware Quad-DVI output support (Limited to workstation editions)
230W consumption
Multi-GPU cluster solutions will be available for the workstation market only until March, 2007.

Processing Power:
105,000,000,000 SOps (Shader Operations Per Second)
2,000,000,000 TCps (Triangle Calculations Per Second)
28 GTps (Gigatexels Per Second)

Level505 claims AMD is expected to equip the ATI R600 with GDDR3 and GDDR4 memory with the GDDR3 endowed model launching in January. Memory clocks have been set at 900 MHz for GDDR3 models and 1.1 GHz for GDDR4 models. Memory bandwidth of the ATI R600 is significantly higher than NVIDIA's GeForce 8800-series. Total memory bandwidth varies from 115GB/s on GDDR3 equipped models to 140GB/s on GDDR4 equipped models. Other notable hardware features include hardware support for quad DVI outputs, but utilizing all four outputs are limited to FireGL workstation edition cards.

The published results are very promising with AMD's ATI R600 beating out NVIDIA's GeForce 8800 GTX in most benchmarks. The performance delta varies from 8% up to 42% depending on the game benchmark.
