GeForce GTX 750 vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which has clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 750 should perform much faster than the Radeon R5 M330 in general. (explain)

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

Texel Rate

The GeForce GTX 750 is much (about 58%) more effective at texture filtering than the Radeon R5 M330. (explain)

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

Pixel Rate

The GeForce GTX 750 should be quite a bit (about 98%) more effective at AA than the Radeon R5 M330, and also will be capable of handling higher resolutions without slowing down too much. (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: Bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once 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 AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
