GeForce GT 210 vs Radeon R9 M265X

Intro

Compare all that to the Radeon R9 M265X, which comes with core speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M265X should be 463% quicker than the GeForce GT 210 overall, due to its higher bandwidth. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 59200 (463%)

Texel Rate

The Radeon R9 M265X will be quite a bit (more or less 388%) more effective at anisotropic filtering than the GeForce GT 210. (explain)

Radeon R9 M265X		23000 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 18288 (388%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M265X is the winner, and very much so. (explain)

Radeon R9 M265X		9200 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 6844 (290%)

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 one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units 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 number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
