GeForce GT 240 GDDR5 vs Radeon R7 250X 2GB

Intro

Compare all of that to the Radeon R7 250X 2GB, which comes with core speeds of 1000 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 240 GDDR5		70 Watts
Radeon R7 250X 2GB		95 Watts
	Difference: 25 Watts (36%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 250X 2GB should perform much faster than the GeForce GT 240 GDDR5 overall. (explain)

Radeon R7 250X 2GB		72000 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 17600 (32%)

Texel Rate

The Radeon R7 250X 2GB will be quite a bit (approximately 127%) more effective at anisotropic filtering than the GeForce GT 240 GDDR5. (explain)

Radeon R7 250X 2GB		40000 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 22400 (127%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 250X 2GB is superior to the GeForce GT 240 GDDR5, and very much so. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 11600 (264%)

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 (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 are applied per 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 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 maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
