GeForce GTX 460 vs Radeon R9 M380

Intro

The GeForce GTX 460 features a core clock frequency of 675 MHz and a GDDR5 memory speed of 900 MHz. It also makes use of a 192-bit memory bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 TAUs, and 24 Raster Operation Units.

Compare those specs to the Radeon R9 M380, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory works at a speed of 1500 MHz on this model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M380 should theoretically be just a bit better than the GeForce GTX 460 in general. (explain)

Radeon R9 M380 96000 MB/sec
GeForce GTX 460 86400 MB/sec
Difference: 9600 (11%)

Texel Rate

The Radeon R9 M380 should be a small bit (approximately 6%) better at anisotropic filtering than the GeForce GTX 460. (explain)

Radeon R9 M380 40000 Mtexels/sec
GeForce GTX 460 37800 Mtexels/sec
Difference: 2200 (6%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 is superior to the Radeon R9 M380, but only just. (explain)

GeForce GTX 460 16200 Mpixels/sec
Radeon R9 M380 16000 Mpixels/sec
Difference: 200 (1%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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