GeForce GTX 750 vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which comes with GPU core speed of 1030 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 will be 456% quicker than the Radeon R5 M330 in general, because of its greater bandwidth. (explain)

GeForce GTX 750		80000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 65600 (456%)

Texel Rate

The GeForce GTX 750 is much (approximately 58%) better at AF than the Radeon R5 M330. (explain)

GeForce GTX 750		32640 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 12040 (58%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 750 is the winner, by a large margin. (explain)

GeForce GTX 750		16320 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 8080 (98%)

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 max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
