(*) GeForce FX series has an Array-based Vertex Shader. Here is how the released versions of the "GeForce 6" series family compare to Nvidia's previous flagship GPU, the GeForce FX 5950 Ultra, in addition to the comparable units of ATI's newly released for the time Radeon X800 and X850 series: These problems seem to happen only on Direct3D based applications and do not affect OpenGL. Problems that have been known to arise are freezing, artifacts, reboots, and other issues that make gaming and use of 3D applications almost impossible. In addition, motherboards with some VIA and SIS chipsets and an AMD Athlon XP processor seemingly have compatibility problems with the GeForce 66 GPUs. PureVideo functionality varies by model, with some models lacking WMV9 and/or H.264 acceleration. Shader Model 3.0 was quickly adopted by game developers because it was quite simple to convert existing shaders coded with SM 2.0/2.0A/2.0B to version 3.0, and it offered noticeable performance improvements across the entire GeForce 6 line. 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. Nvidia was the first to deliver Shader Model 3.0 (SM3) capability in its GPUs.
Display ConnectorsĪPIs supported, including particular versions of those APIs.Nvidia PureVideo technology is the combination of a dedicated video processing core and software which decodes H.264, VC-1, WMV, and MPEG-2 videos with reduced CPU utilization. OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). Types and number of video connectors present on the reviewed GPUs.
Integrated GPUs have no dedicated VRAM and use a shared part of system RAM. Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth.
For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). Useful when choosing a future computer configuration or upgrading an existing one. Information on compatibility with other computer components. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed.
