GeForce GTX 275 vs GeForce GTX 650 Ti 2GB

Intro

The GeForce GTX 275 uses a 55 nm design. nVidia has clocked the core speed at 633 MHz. The GDDR3 memory runs at a speed of 1134 MHz on this specific card. It features 240 SPUs as well as 80 TAUs and 28 ROPs.

Compare those specifications to the GeForce GTX 650 Ti 2GB, which has a GPU core clock speed of 928 MHz, and 2048 MB of GDDR5 RAM running at 1350 MHz through a 128-bit bus. It also is comprised of 768 Stream Processors, 64 Texture Address Units, and 16 ROPs.

GeForce GTX 650 Ti 2GB 86400 MB/sec
Difference: 40608 (47%)

Texel Rate

The GeForce GTX 650 Ti 2GB will be a bit (approximately 17%) more effective at anisotropic filtering than the GeForce GTX 275. (explain)

GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
GeForce GTX 275 50640 Mtexels/sec
Difference: 8752 (17%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 275 is the winner, not by a very large margin though. (explain)

GeForce GTX 275 17724 Mpixels/sec
GeForce GTX 650 Ti 2GB 14848 Mpixels/sec
Difference: 2876 (19%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, 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 the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
