GeForce GTX 465 vs GeForce GTX 650

Intro

The GeForce GTX 465 has a core clock frequency of 607 MHz and a GDDR5 memory speed of 802 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 352 SPUs, 44 TAUs, and 32 ROPs.

Compare all of that to the GeForce GTX 650, which uses a 28 nm design. nVidia has set the core frequency at 1058 MHz. The GDDR5 memory works at a speed of 1250 MHz on this specific model. It features 384 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 max fill rate.
