GeForce GTX Titan Black vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which comes with core clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX Titan Black, in theory, should be much faster than the Radeon R5 M330 overall. (explain)

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

Texel Rate

The GeForce GTX Titan Black should be quite a bit (more or less 936%) better at texture filtering than the Radeon R5 M330. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 192760 (936%)

Pixel Rate

The GeForce GTX Titan Black is quite a bit (approximately 418%) faster with regards to AA than the Radeon R5 M330, and also will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 34432 (418%)

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 (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
