With half the pixel pipelines and vertex shaders of the 6800 GT, and a smaller 128-bit memory bus, the lower-performance and lower-cost 6600 is the mainstream product of the GeForce 6 series.Launched on April 14, 2004, the GeForce 6 family introduced PureVideo post-processing for video, SLI technology, and Shader Model 3.0 support (compliant with Microsoft DirectX 9.0c specification and OpenGL 2.0).SLI-capability is limited to select members of the GeForce 6 family; 6500 and above.
SLI is only available for cards utilizing the PCI-Express bus. SM3 extends SM2 in a number of ways: standard FP32 (32-bit floating-point) precision, dynamic branching, increased efficiency and longer shader lengths are the main additions. Shader Model 3.0 was quickly adopted by game developers because it was quite simple to convert existing shaders coded with SM 2.02.0A2.0B to version 3.0, and it offered noticeable performance improvements across the entire GeForce 6 line. Problems that have been known to arise are freezing, artifacts, reboots, and other issues that make gaming and use of 3D applications almost impossible. These problems seem to happen only on Direct3D based applications and do not affect OpenGL. As the very first GeForce 6 model, the 16 pixel pipeline GeForce 6800 Ultra (NV40) was 2 to 2.5 times faster than Nvidias previous top-line product (the GeForce FX 5950 Ultra), packed four times the number of pixel pipelines, twice the number of texture units and added a much improved pixel-shader architecture. Nvidia added support for the PCI Express (PCIe) bus in later GeForce 6 products, usually by use of an AGP-PCIe bridge chip. In the case of the 6800 GT and 6800 Ultra, Nvidia developed a variant of the NV40 chip called the NV45. Later, when Nvidias GPUs were designed to use PCIe natively, the bidirectional bridge chip allowed them to be used in AGP cards. ATI, initially a critic of the bridge chip, eventually designed a similar mechanism for their own cards. The 6800 series was also incorporated into laptops with the GeForce Go 6800 and Go 6800 Ultra GPUs. But perhaps ironically, the first GeForce product(s) to offer PureVideo, the AGP GeForce 6800GTUltra, failed to support all of PureVideos advertised features. User and web reports showed little if any difference between PureVideo enabled GeForces and non-Purevideo cards. The prolonged public silence of Nvidia, after promising updated drivers, and test benchmarks gathered by users led the user community to conclude that the WMV9 decoder component of the AGP 6800s PureVideo unit is either non-functional or intentionally disabled. Of course, todays standard computers are fast enough to play WMV9 video and other sophisticated codecs like MPEG-4, H.264 or VP8 without hardware acceleration. The AGP version, however, uses the original NV40 chip and 6800 GT circuit board and the inactive pixel and vertex pipelines may potentially be unlockable. However, the PCI Express version lacks them entirely, preventing such modifications. Recent PCIe variants have the NV41 (IBM 0.13 micrometre) or NV42 ( TSMC 0.11 micrometre) cores, which are native PCIe implementations and do not have an integrated AGP bridge chip. The AGP version of the video card contains four masked pixel pipelines and one masked vertex shader, which are potentially unlockable through software mods. PCI-Express 6800 cards are incapable of such modifications, because the masked pixel pipelines and vertex buffers are nonexistent. It is produced using three cores (NV40NV41NV42), four memory configurations (128 MB DDR, 256 MB DDR, 128 MB GDDR3, 256 MB GDDR3, and 512 MB GDDR2), and has clock speeds ranging from 300-425 MHz (core) and 600-1000 MHz (memory). XT cards based on the NV40 core contain eight masked pixel pipelines and two masked vertex shaders, and those based on the NV42 core contain four masked pipelines and one masked shader (for some reason, the NV42 cards are almost never unlockable.
