GeForce GTX 260 vs GeForce GTX 650 Ti

Intro

Compare those specs to the GeForce GTX 650 Ti, which has a core clock frequency 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 comprised of 768 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti		110 Watts
GeForce GTX 260		182 Watts
	Difference: 72 Watts (65%)

Memory Bandwidth

Theoretically, the GeForce GTX 260 should perform quite a bit faster than the GeForce GTX 650 Ti in general. (explain)

GeForce GTX 260		111888 MB/sec
GeForce GTX 650 Ti		86400 MB/sec
	Difference: 25488 (30%)

Texel Rate

The GeForce GTX 650 Ti is quite a bit (approximately 61%) faster with regards to anisotropic filtering than the GeForce GTX 260. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 22528 (61%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 260 is superior to the GeForce GTX 650 Ti, but it probably won't make a huge difference. (explain)

GeForce GTX 260		16128 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 1280 (9%)

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 maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
