GeForce 8800 GS vs GeForce GTX 650 Ti

Intro

The GeForce 8800 GS makes use of a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR3 memory is set to run at a speed of 800 MHz on this particular model. It features 96 SPUs along with 48 Texture Address Units and 12 Rasterization Operator Units.

Compare that to the GeForce GTX 650 Ti, which has a core clock speed of 928 MHz and a GDDR5 memory frequency of 1350 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 768 SPUs, 64 TAUs, and 16 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 ability to reach the maximum fill rate.
