GeForce GTX 560 Ti vs Radeon R9 M380

Intro

Compare all that to the Radeon R9 M380, which uses a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory works at a speed of 1500 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 560 Ti should theoretically be much faster than the Radeon R9 M380 in general. (explain)

GeForce GTX 560 Ti		128256 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 32256 (34%)

Texel Rate

The GeForce GTX 560 Ti is quite a bit (more or less 32%) more effective at AF than the Radeon R9 M380. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 12608 (32%)

Pixel Rate

The GeForce GTX 560 Ti should be much (about 64%) more effective at AA than the Radeon R9 M380, and able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 10304 (64%)

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 data (in units of megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few 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.
