GeForce GTX Titan X vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which has a core clock frequency of 1030 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It features 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX Titan X should in theory be quite a bit faster than the Radeon R5 M330 overall. (explain)

GeForce GTX Titan X		336000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 321600 (2233%)

Texel Rate

The GeForce GTX Titan X should be a lot (more or less 832%) better at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 171400 (832%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX Titan X is a better choice, by a large margin. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 87760 (1065%)

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 (measured in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
