GeForce GTX 750 vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which features a core clock speed of 1030 MHz and a DDR3 memory frequency of 900 MHz. It also features a 64-bit memory bus, and makes use of a 28 nm design. It is made up of 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, 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 quite a bit (approximately 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 much (about 98%) better at anti-aliasing than the Radeon R5 M330, and also should be capable of handling higher screen resolutions without losing too much performance. (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 max amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
