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

Intro

The GeForce GTX 650 Ti 2GB uses a 28 nm design. nVidia has set the core speed at 928 MHz. The GDDR5 memory runs at a frequency of 1350 MHz on this card. It features 768 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Compare all of that to the Radeon HD 5750 1GB, which comes with a clock speed of 700 MHz and a GDDR5 memory speed of 1150 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is comprised of 720(144x5) SPUs, 36 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
