Details of AMD's next generation Radeon hit the web

Newly created site Level 505 has leaked benchmarks 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. These early specifications and launch dates line up with what DailyTech has already published and are present on ATI internal roadmaps as of workweek 49.

Preliminary specifications from Level 505 of the ATI R600 are as follows:
  • 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 [sic] internal processing
  • Hardware support for GPU clustering (any x^2 [sic] number, not limited to Dual or Quad-GPU)
  • Hardware DVI-HDCP support (High Definition Copy Protocol)
  • Hardware Quad-DVI output support (Limited to workstation editions)
  • 230W TDP PCI-SIG compliant
This time around it appears AMD is going for a different approach by equipping the ATI R600 with less unified shaders than NVIDIA’s recently launched GeForce 8800 GTX. However, the unified shaders found on the ATI R600 can complete more shader operations per clock cycle.

ATI's interal guidance states the R600 will have 320 stream processors at launch; 64 4-way unified shaders only accounts for 256 of these stream processors.

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.  As recent as two weeks ago, ATI roadmaps had said this GDDR3 launch was canceled.  These same roadmaps claim the production date for R600 is February 2007, which would be after a January 22nd launch.

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.

There’s also integrated support for multi-GPU clustering technologies such as CrossFire too. The implementation on the ATI R600 allows any amount ofATI R600 GPUs to operate together in powers of two. Expect multi-GPU configurations with greater than two GPUs to only be available for the workstation markets though.

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.

When DailyTech contacted the site owner to get verification of the benchmarks, the owner replied that the benchmark screenshots could not be published due to origin-specific markers that would trace the card back to its source -- the author mentioned the card is part of the Microsoft Vista driver certification program.

If Level505's comments seem a little too pro-ATI, don't be too surprised.  When asked if the site was affiliated in any way to ATI or AMD, the owner replied to DailyTech with the statement that "two staff members of ours are directly affiliated with AMD's business [development] division."

just out of boredom i started comparising the numbers on this site now that its been "updated" or atleast part 2 is there, and i found something amiss.

just out of curisoity i looked up the anandtech.com review of the 8800gtx, check out if the numbers compare a little. now the testing rig of level 505 is better (higher clocked, raid disks) than the rig for the 8800gtx on anand. both numbers come from 1600x1200 4xaa 16xaf. same for the ati crossfire setup, since 505 didnt 8use a single 1950xt i'll leave that out. also oblivion was done on both sides but different settings.

fear test:
anandtech 8800GTX: 84
level 505 8800GTX: 75,9
anandtech X1950XT CF: 94
level 505 X1950XT CF: 92,6

battlefield 2:
anandtech 8800GTX: 142,7
level 505 8800GTX: 148,9
anandtech X1950XT CF: 134,1
level 505 X1950XT CF: 114,1

http://anandtech.com/video/showdoc.aspx?i=2870&p=2...

now knowing that level 505 has the better rig and more up-to-date drivers theres no way theres such a gap between reviews in fear. nor is there an explanation, why, if in fear the card peforms much worse then the anandtech sample, it blows away anand's 8800gtx in BF2. that just makes no sense. and to me, the problems they had with BF2 running properly on a 1950xt CF (20 fps less then anand, cmon!) with the fact that they say themselves they "rushed it" just takes away all their credebility.

Yeah, HardOCP reviewed and 8800gtx on 1-1-2007 and their oblivion numbers where way higher than what is recorded on this site (level505).
