Nvidia Titan X vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which uses a 28 nm design. AMD has set the core frequency at 1030 MHz. The DDR3 memory is set to run at a frequency of 900 MHz on this card. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Nvidia Titan X should be 3313% faster than the Radeon R5 M330 overall, because of its higher data rate. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 477120 (3313%)

Texel Rate

The Nvidia Titan X is much (approximately 1441%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 296808 (1441%)

Pixel Rate

If using a high resolution is important to you, then the Nvidia Titan X is the winner, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 127792 (1551%)

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 MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
