GeForce GTX 750 Ti vs Radeon R9 M265X

Intro

Compare that to the Radeon R9 M265X, which has GPU clock speed of 575 MHz, and 2048 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 750 Ti, in theory, should be just a bit faster than the Radeon R9 M265X in general. (explain)

GeForce GTX 750 Ti		86400 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 750 Ti will be quite a bit (more or less 77%) faster with regards to anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 17800 (77%)

Pixel Rate

The GeForce GTX 750 Ti is quite a bit (about 77%) more effective at FSAA than the Radeon R9 M265X, and should be able to handle higher resolutions better. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 7120 (77%)

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 data (counted in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could 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 filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
