GeForce GTX 465 vs GeForce GTX 650 Ti

Intro

Compare all of that to the GeForce GTX 650 Ti, which has core clock speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 RAM. It features 768 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 650 Ti		86400 MB/sec
	Difference: 16192 (19%)

Texel Rate

The GeForce GTX 650 Ti will be much (about 122%) better at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 32684 (122%)

Pixel Rate

The GeForce GTX 465 is quite a bit (more or less 31%) faster with regards to FSAA than the GeForce GTX 650 Ti, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 4576 (31%)

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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
