GeForce GTX 460 vs Radeon R9 M380

Intro

The GeForce GTX 460 uses a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 memory runs at a speed of 900 MHz on this particular model. It features 336 SPUs along with 56 Texture Address Units and 24 ROPs.

Compare all of that to the Radeon R9 M380, which features GPU core speed of 1000 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M380 should be a small bit faster than the GeForce GTX 460 overall. (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 bit (about 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

The GeForce GTX 460 is a bit (approximately 1%) better at anti-aliasing than the Radeon R9 M380, and should be capable of handling higher screen resolutions while still performing well. (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 max amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
