GeForce GTS 250 1GB vs Radeon R7 240

Intro

The GeForce GTS 250 1GB comes with a GPU core clock speed of 738 MHz, and the 1024 MB of GDDR3 RAM runs at 1100 MHz through a 256-bit bus. It also features 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon R7 240, which has GPU clock speed of 730 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 128-bit bus. It also is made up of 320 Stream Processors, 20 TAUs, and 8 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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