GeForce 8800 Ultra vs GeForce GTX 650 Ti 2GB

Intro

Compare those specifications to the GeForce GTX 650 Ti 2GB, which makes use of a 28 nm design. nVidia has set the core frequency at 928 MHz. The GDDR5 memory runs at a speed of 1350 MHz on this card. It features 768 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Texel Rate

The GeForce GTX 650 Ti 2GB is much (more or less 52%) more effective at anisotropic filtering than the GeForce 8800 Ultra. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 20224 (52%)

Pixel Rate

The GeForce GTX 650 Ti 2GB should be a bit (about 1%) more effective at AA than the GeForce 8800 Ultra, and also will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 160 (1%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
