GeForce GTX 460 2GB vs Radeon R9 M380

Intro

The GeForce GTX 460 2GB uses a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 memory works at a frequency of 900 MHz on this particular card. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

Compare all of that to the Radeon R9 M380, which comes with a GPU core clock speed of 1000 MHz, and 4096 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 2GB will be 20% quicker than the Radeon R9 M380 overall, due to its greater data rate. (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 bit (approximately 6%) more effective at AF 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

If running with high levels of AA is important to you, then the GeForce GTX 460 2GB is superior to the Radeon R9 M380, by a large margin. (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 information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
