GeForce 9800 GTX vs Radeon R7 250X 2GB

Intro

Compare all that to the Radeon R7 250X 2GB, which features GPU core speed of 1000 MHz, and 2048 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce 9800 GTX		70400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The GeForce 9800 GTX will be a little bit (more or less 8%) more effective at AF than the Radeon R7 250X 2GB. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 3200 (8%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 250X 2GB is superior to the GeForce 9800 GTX, by far. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 5200 (48%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core 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 chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
