GeForce GTX 650 Ti 2GB vs Radeon HD 5750 1GB

Intro

The GeForce GTX 650 Ti 2GB comes with a GPU core speed of 928 MHz, and the 2048 MB of GDDR5 memory is set to run at 1350 MHz through a 128-bit bus. It also is comprised of 768 Stream Processors, 64 Texture Address Units, and 16 ROPs.

Compare those specs to the Radeon HD 5750 1GB, which makes use of a 40 nm design. AMD has set the core frequency at 700 MHz. The GDDR5 memory is set to run at a frequency of 1150 MHz on this model. It features 720(144x5) SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that can be processed in one second. This figure is worked out 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
