GeForce 9400 GT 256MB vs Radeon R7 250X 2GB

Intro

The GeForce 9400 GT 256MB comes with a core clock frequency of 550 MHz and a GDDR2 memory frequency of 400 MHz. It also features a 128-bit memory bus, and uses a 65 nm design. It is made up of 16 SPUs, 8 TAUs, and 4 ROPs.

Compare that to the Radeon R7 250X 2GB, which has GPU core speed of 1000 MHz, and 2048 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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