GeForce GTX 465 vs GeForce GTX 650 Ti 2GB

Intro

The GeForce GTX 465 has a GPU core clock speed of 607 MHz, and the 1024 MB of GDDR5 memory is set to run at 802 MHz through a 256-bit bus. It also is made up of 352 Stream Processors, 44 Texture Address Units, and 32 Raster Operation Units.

Compare that to the GeForce GTX 650 Ti 2GB, which comes with GPU core speed of 928 MHz, and 2048 MB of GDDR5 memory running at 1350 MHz through a 128-bit bus. It also features 768 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB 110 Watts
GeForce GTX 465 200 Watts
Difference: 90 Watts (82%)

Memory Bandwidth

In theory, the GeForce GTX 465 should be 19% quicker than the GeForce GTX 650 Ti 2GB in general, because of its higher data rate. (explain)

GeForce GTX 465 102592 MB/sec
GeForce GTX 650 Ti 2GB 86400 MB/sec
Difference: 16192 (19%)

Texel Rate

The GeForce GTX 650 Ti 2GB will be a lot (more or less 122%) faster with regards to texture filtering than the GeForce GTX 465. (explain)

GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 32684 (122%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 465 is the winner, and very much so. (explain)

GeForce GTX 465 19424 Mpixels/sec
GeForce GTX 650 Ti 2GB 14848 Mpixels/sec
Difference: 4576 (31%)

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: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
