GeForce GTX 260 Core 216 vs GeForce GTX 650 Ti

Intro

Compare all of that to the GeForce GTX 650 Ti, which features 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 Texture Address Units and 16 Rasterization Operator Units.

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

Texel Rate

The GeForce GTX 650 Ti should be much (more or less 43%) better at anisotropic filtering than the GeForce GTX 260 Core 216. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 260 Core 216 is a better choice, but not by far. (explain)

GeForce GTX 260 Core 216		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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
