Geforce GTX 760 vs Radeon R9 M380

Intro

Compare those specs to the Radeon R9 M380, which comes with a core clock frequency of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Geforce GTX 760 should theoretically be a lot superior to the Radeon R9 M380 overall. (explain)

Geforce GTX 760		192256 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 96256 (100%)

Texel Rate

The Geforce GTX 760 is much (approximately 135%) more effective at AF than the Radeon R9 M380. (explain)

Geforce GTX 760		94080 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 54080 (135%)

Pixel Rate

If running with high levels of AA is important to you, then the Geforce GTX 760 is a better choice, by far. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 15360 (96%)

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 max amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core 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 applied in a second.

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