GeForce GTX 460 vs Radeon R9 M380

Intro

The GeForce GTX 460 uses a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 memory is set to run at a speed of 900 MHz on this specific card. It features 336 SPUs as well as 56 Texture Address Units and 24 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M380, which features GPU core 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 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M380 should theoretically be just a bit superior to the GeForce GTX 460 in general. (explain)

Radeon R9 M380 96000 MB/sec
GeForce GTX 460 86400 MB/sec
Difference: 9600 (11%)

Texel Rate

The Radeon R9 M380 should be just a bit (more or less 6%) more effective at AF than the GeForce GTX 460. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 460 is a better choice, but not by far. (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 data (counted in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
