GeForce GTX 650 vs Radeon HD 7790

Intro

The GeForce GTX 650 features a GPU core speed of 1058 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1250 MHz through a 128-bit bus. It also is made up of 384 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon HD 7790, which features a clock speed of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
