GeForce GTX 460 2GB vs Radeon R9 M380

Intro

The GeForce GTX 460 2GB comes with core clock speeds of 675 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR5 RAM. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 2GB, in theory, should perform just a bit faster than the Radeon R9 M380 in general. (explain)

GeForce GTX 460 2GB 115200 MB/sec
Radeon R9 M380 96000 MB/sec
Difference: 19200 (20%)

Texel Rate

The Radeon R9 M380 should be a small bit (approximately 6%) more effective at texture filtering than the GeForce GTX 460 2GB. (explain)

Radeon R9 M380 40000 Mtexels/sec
GeForce GTX 460 2GB 37800 Mtexels/sec
Difference: 2200 (6%)

Pixel Rate

The GeForce GTX 460 2GB should be much (approximately 35%) better at AA than the Radeon R9 M380, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 460 2GB 21600 Mpixels/sec
Radeon R9 M380 16000 Mpixels/sec
Difference: 5600 (35%)

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 maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
