GeForce GTX 260 216SP 55 nm vs GeForce GTX 650 Ti

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti		110 Watts
GeForce GTX 260 216SP 55 nm		171 Watts
	Difference: 61 Watts (55%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 260 216SP 55 nm should in theory be a lot superior to the GeForce GTX 650 Ti in general. (explain)

GeForce GTX 260 216SP 55 nm		111888 MB/sec
GeForce GTX 650 Ti		86400 MB/sec
	Difference: 25488 (30%)

Texel Rate

The GeForce GTX 650 Ti should be much (more or less 43%) more effective at texture filtering than the GeForce GTX 260 216SP 55 nm. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
	Difference: 17920 (43%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 260 216SP 55 nm is the winner, not by a very large margin though. (explain)

GeForce GTX 260 216SP 55 nm		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 transported past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This 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 graphics 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 write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
