GeForce 9800 GTX+ vs Radeon R7 250

Intro

Compare all that to the Radeon R7 250, which has core speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

GeForce 9800 GTX+		70400 MB/sec
	Difference: 3200 (5%)

Texel Rate

The GeForce 9800 GTX+ should be much (about 97%) more effective at texture filtering than the Radeon R7 250. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 23232 (97%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 9800 GTX+ is superior to the Radeon R7 250, by a large margin. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 3808 (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 largest amount of information (measured in megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number 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 higher the texel rate, the better the video card will be at 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 the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
