GeForce 9800 GT 512MB vs Radeon R7 250X 2GB
Intro
The GeForce 9800 GT 512MB makes use of a 65/55 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this particular model. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon R7 250X 2GB, which comes with a GPU core clock speed of 1000 MHz, and 2048 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once 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 higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video 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 amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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 of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
