GeForce GTX 460 2GB vs GeForce GTX 650 Ti 2GB

Intro

The GeForce GTX 460 2GB has core speeds of 675 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR5 memory. It features 336 SPUs as well as 56 TAUs and 32 ROPs.

Compare all of that to the GeForce GTX 650 Ti 2GB, which has a clock frequency of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 768 SPUs, 64 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
