NVIDIA prepares its next-generation mid-range and mainstream DirectX 10 GPUs

Earlier today DailyTech received it's briefiing on NVIDIA’s upcoming GeForce 8600GTS, 8600GT and 8500GT graphics processors. NVIDIA’s GeForce 8600GTS and 8600GT are G84-based GPUs and target the mid-range markets. The lower-positioned G86-based GeForce 8500GT serves as the flagship low to mid-range graphics card.
The budget-priced trio feature full support for DirectX 10 features including pixel and vertex shader model 4.0. NVIDIA has yet to reveal the amount of shaders or shader clocks though. Nevertheless, the trio supports NVIDIA SLI and PureVideo technologies.

NVIDIA GeForce 8600GT

NVIDIA touts three dedicated video engines on the G84 and G86-based graphics cards for PureVideo processing. The video engines provide MPEG-2 high-definition and WMV HD video playback up to resolutions of 1080p. G84 and G86 support hardware accelerated decoding of H.264 video as well; however, NVIDIA makes no mention of VC-1 decoding. G84 and G86 also feature advanced post-processing video algorithms. Supported algorithms include spatial-temporal de-interlacing, inverse 2:2, 3:2 pull-down and 4-tap horizontal, and 5-tap vertical video scaling.
At the top of the mid-range lineup is the GeForce 8600GTS. The G84-based graphics core clocks in at 675 MHz. NVIDIA pairs the GeForce 8600GTS with 256MB of GDDR3 memory clocked at 1000 MHz. The memory interfaces with the GPU via a 128-bit bus. The GeForce 8600GTS does not integrate HDCP keys on the GPU. Add-in board partners will have to purchase separate EEPROMs with HDCP keys; however, all GeForce 8600GTS-based graphics cards feature support for HDCP.
GeForce 8600GTS-based graphics cards require an eight-layer PCB. Physically, the cards measure in at 7.2 x 4.376 inches and available in full-height only. NVIDIA GeForce 8600GTS graphics cards feature a PCIe x16 interface, unlike ATI’s upcoming RV630. GeForce 8600GTS-based cards still require external PCIe power. NVIDIA estimates total board power consumption at around 71-watts.
Supported video output connectors include dual dual-link DVI, VGA, SDTV and HDTV outputs, and analog video inputs. G84-based GPUs do not support a native HDMI output. Manufacturers can adapt one of the DVI-outputs for HDMI.
NVIDIA’s GeForce 8600GT is not as performance oriented as the 8600GTS. The GeForce 8600GT GPU clocks in at a more conservative 540 MHz. The memory configuration has more flexibility, letting manufacturers decide between 256MB or 128MB of GDDR3 memory. NVIDIA specifies the memory clock at 700 MHz. The GeForce 8600GT shares the same 128-bit memory interface as the 8600GTS. HDCP support on GeForce 8600GT is optional. The GPU and reference board design support the required HDCP keys EEPROM, however, the implementation is up to NVIDIA’s add-in board partners.
GeForce 8600GT-based graphics cards only require a six-layer PCB instead of the eight-layer PCB of the 8600GTS. The physical board size is also smaller too – measuring in at 6.9 x 4.376 inches. GeForce 8600GT-based cards do not require external PCIe power. NVIDIA rates the maximum board power consumption at 43-watts – 28-watts less than the 8600GTS.
The GeForce 8600GT supports similar video outputs as the 8600GTS, however, the 8600GT does not support video input features.
NVIDIA has revealed very little information on the GeForce 8500GT besides support for GDDR3 and DDR2 memory. It supports dual dual-link DVI, VGA and TV outputs as well.
Expect NVIDIA to pull the wraps off its GeForce 8600GTS, 8600GT and 8500GT next quarter in time to take on AMD’s upcoming RV630 and RV610.

First Overclocked GeForce 8800 Cards From XFX: X-Rated Speeds

As if Nvidia's GeForce 8800 cards weren't already fast enough, XFX is taking it upon themselves to be the first company to overclock them, sending them into hyperspeed territory. At the head of the pack is the 8800 GTX XXX Edition which is overclocked from 575MHz to 630MHz. Meanwhile the core clock on the 8800 GTS XXX Edition gets a kick up from 500 MHz to 550MHz. Pricing on the cards isn't out yet, but you can expect to pay a nice premium for them when they do come out. – Louis Ramirez

Early AMD ATI "R600" Specs, Benchmarks Leaked

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.

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 of ATI 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."

AMD lent $650 million for New York State fab

We wanted to know which is the best overclocking platform for Intel’s Core 2 Duo and some people who are really into it said we should maybe wait for the Nforce 680i motherboards.

They should be the fastest for both memory and CPU overclocking and the boards should emerge in the following days.

We know these will end up faster than both Intel’s high-end chipset 975X and the P965 although we know it will have a rough ride to beat RD600 from DAAMIT.

It supports three PCIe slots, two for graphic cards and one for physics, I guess they saw this one from ATI. We know that the memory can hit 1200MHz if not even higher. The boards based on it should be announced on the 8th, together with the new Geforce thingummy.
