GeForce GTX 460 vs GeForce GTX 650 Ti

Intro

The GeForce GTX 460 features a GPU clock speed of 675 MHz, and the 768 MB of GDDR5 memory is set to run at 900 MHz through a 192-bit bus. It also is made up of 336 Stream Processors, 56 TAUs, and 24 ROPs.

Compare those specifications to the GeForce GTX 650 Ti, which features a GPU core clock speed of 928 MHz, and 1024 MB of GDDR5 memory set to run at 1350 MHz through a 128-bit bus. It also is made up of 768 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

3DMark Fire Strike Graphics Score

GeForce GTX 650 Ti 3434 points
GeForce GTX 460 2557 points
Difference: 877 (34%)

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 110 Watts
GeForce GTX 460 150 Watts
Difference: 40 Watts (36%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The GeForce GTX 650 Ti is much (about 57%) more effective at AF than the GeForce GTX 460. (explain)

GeForce GTX 650 Ti 59392 Mtexels/sec
GeForce GTX 460 37800 Mtexels/sec
Difference: 21592 (57%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 460 16200 Mpixels/sec
GeForce GTX 650 Ti 14848 Mpixels/sec
Difference: 1352 (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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 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 applied per second. This figure is calculated by multiplying the total number of texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
