GeForce GTX 465 vs GeForce GTX 650 Ti

Intro

Compare all that to the GeForce GTX 650 Ti, which comes with GPU clock speed of 928 MHz, and 1024 MB of GDDR5 RAM running at 1350 MHz through a 128-bit bus. It also is made up of 768 Stream Processors, 64 TAUs, and 16 ROPs.

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

Texel Rate

The GeForce GTX 650 Ti should be a lot (about 122%) more effective at AF 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 should be much (more or less 31%) better at full screen anti-aliasing than the GeForce GTX 650 Ti, and capable of handling higher resolutions while still performing well. (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 max amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, 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 AA, HDR and high resolutions.

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

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