GeForce GTX 460 2GB vs Radeon R9 M380

Intro

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

Compare that to the Radeon R9 M380, which uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 RAM works at a speed of 1500 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 460 2GB should in theory be a bit better 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 is a small bit (approximately 6%) more effective at anisotropic 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

If using high levels of AA is important to you, then the GeForce GTX 460 2GB is a better choice, 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 largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core 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 in a second.

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