GeForce GTX Titan Black vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which comes with a clock frequency of 1030 MHz and a DDR3 memory frequency of 900 MHz. It also uses a 64-bit memory bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 Texture Address Units, 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 a lot (approximately 936%) more effective at anisotropic 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 much (more or less 418%) better at full screen anti-aliasing than the Radeon R5 M330, and also will be capable of handling higher screen resolutions without slowing down too much. (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 max amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock 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 most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
