GeForce 9800 GTX+ vs Radeon R7 250

Intro

Compare those specs to the Radeon R7 250, which has a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 memory running at 1150 MHz through a 128-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Power Consumption (Max TDP)

Radeon R7 250		65 Watts
GeForce 9800 GTX+		145 Watts
	Difference: 80 Watts (123%)

Memory Bandwidth

As far as performance goes, the Radeon R7 250 should theoretically be a small bit superior to the GeForce 9800 GTX+ overall. (explain)

Radeon R7 250		73600 MB/sec
GeForce 9800 GTX+		70400 MB/sec
	Difference: 3200 (5%)

Texel Rate

The GeForce 9800 GTX+ is quite a bit (about 97%) better at anisotropic 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 running with lots of anti-aliasing is important to you, then the GeForce 9800 GTX+ is the winner, and very much so. (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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
