GeForce GTX 460 vs Radeon R9 M380

Intro

The GeForce GTX 460 features a GPU clock speed of 675 MHz, and the 768 MB of GDDR5 RAM is set to run at 900 MHz through a 192-bit bus. It also is made up of 336 Stream Processors, 56 TAUs, and 24 ROPs.

Compare that to the Radeon R9 M380, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 RAM runs at a frequency of 1500 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M380 should in theory perform just a 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 will be just a bit (more or less 6%) faster with regards to texture 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 a high screen resolution is important to you, then the GeForce GTX 460 is superior to the Radeon R9 M380, not by a very large margin though. (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 transferred past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
