GeForce GTX 460 1GB vs Radeon R9 M385X

Intro

The GeForce GTX 460 1GB has a GPU core clock speed of 675 MHz, and the 1024 MB of GDDR5 RAM is set to run at 900 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 TAUs, and 32 ROPs.

Compare those specs to the Radeon R9 M385X, which uses a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this particular card. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 460 1GB should in theory be just a bit superior to the Radeon R9 M385X overall. (explain)

GeForce GTX 460 1GB 115200 MB/sec
Radeon R9 M385X 96000 MB/sec
Difference: 19200 (20%)

Texel Rate

The Radeon R9 M385X is much (approximately 63%) more effective at anisotropic filtering than the GeForce GTX 460 1GB. (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce GTX 460 1GB 37800 Mtexels/sec
Difference: 23800 (63%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 460 1GB is a better choice, and very much so. (explain)

GeForce GTX 460 1GB 21600 Mpixels/sec
Radeon R9 M385X 17600 Mpixels/sec
Difference: 4000 (23%)

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 (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 can be processed in one second. This figure 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 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 could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
