GeForce GTX 260 vs GeForce GTX 650 Ti

Intro

Compare all of that to the GeForce GTX 650 Ti, which features core 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		182 Watts
	Difference: 72 Watts (65%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 is 30% faster than the GeForce GTX 650 Ti in general, because of its higher data rate. (explain)

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

Texel Rate

The GeForce GTX 650 Ti will be quite a bit (about 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

The GeForce GTX 260 is a little bit (more or less 9%) faster with regards to anti-aliasing than the GeForce GTX 650 Ti, and also should be capable of handling higher resolutions while still performing well. (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 MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
