GeForce GTX 750 Ti vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which comes with GPU core speed of 1030 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 64-bit bus. It also is comprised of 320 Stream Processors, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 750 Ti will be 500% quicker than the Radeon R5 M330 overall, due to its higher data rate. (explain)

GeForce GTX 750 Ti		86400 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 72000 (500%)

Texel Rate

The GeForce GTX 750 Ti should be a lot (more or less 98%) better at AF than the Radeon R5 M330. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 20200 (98%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 750 Ti is the winner, by a large margin. (explain)

GeForce GTX 750 Ti		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 (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed 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 higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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