GeForce GT 240 GDDR5 vs Radeon R7 250

Intro

The GeForce GT 240 GDDR5 makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 memory runs at a speed of 850 MHz on this card. It features 96 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.

Compare those specs to the Radeon R7 250, which comes with core clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high 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 texture units by the core clock speed of the chip. The better this number, the better the graphics 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 graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
