GeForce GTX 460 SE 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 RAM runs at a frequency of 1500 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 SE should in theory perform a small bit faster than the Radeon R9 M380 overall. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 12800 (13%)

Texel Rate

The Radeon R9 M380 should be a lot (about 28%) better at anisotropic filtering than the GeForce GTX 460 SE. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 8800 (28%)

Pixel Rate

The GeForce GTX 460 SE should be much (about 30%) more effective at AA than the Radeon R9 M380, and should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 4800 (30%)

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 data (counted in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
