GeForce 8800 GTS (G92) vs GeForce GTX 650 Ti 2GB

Intro

The GeForce 8800 GTS (G92) uses a 65 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 RAM runs at a speed of 970 MHz on this specific model. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Compare all that to the GeForce GTX 650 Ti 2GB, which features a clock frequency of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 768 SPUs, 64 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
