GeForce GTX Titan Black vs Radeon R9 M380

Intro

Compare all of that to the Radeon R9 M380, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory runs at a frequency of 1500 MHz on this particular card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX Titan Black should in theory be much faster than the Radeon R9 M380 in general. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 240000 (250%)

Texel Rate

The GeForce GTX Titan Black is quite a bit (more or less 433%) better at anisotropic filtering than the Radeon R9 M380. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 173360 (433%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX Titan Black is superior to the Radeon R9 M380, and very much so. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 26672 (167%)

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 maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most 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 amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
