GeForce GTX Titan vs Radeon R9 M380

Intro

Compare those specifications to the Radeon R9 M380, which has a core clock frequency of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan is 200% faster than the Radeon R9 M380 in general, because of its greater data rate. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 192384 (200%)

Texel Rate

The GeForce GTX Titan is quite a bit (about 369%) better at AF than the Radeon R9 M380. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 147488 (369%)

Pixel Rate

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

GeForce GTX Titan		40176 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 24176 (151%)

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 (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
