GeForce GTX 460 vs Radeon R9 M295X

Intro

The GeForce GTX 460 comes with a GPU core speed of 675 MHz, and the 768 MB of GDDR5 memory runs at 900 MHz through a 192-bit bus. It also is made up of 336 Stream Processors, 56 Texture Address Units, and 24 ROPs.

Compare all that to the Radeon R9 M295X, which makes use of a 28 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM runs at a frequency of 1375 MHz on this specific card. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 460 86400 MB/sec
Difference: 89600 (104%)

Texel Rate

The Radeon R9 M295X should be a lot (approximately 154%) better at texture filtering than the GeForce GTX 460. (explain)

Radeon R9 M295X 96000 Mtexels/sec
GeForce GTX 460 37800 Mtexels/sec
Difference: 58200 (154%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M295X is a better choice, by a large margin. (explain)

Radeon R9 M295X 24000 Mpixels/sec
GeForce GTX 460 16200 Mpixels/sec
Difference: 7800 (48%)

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 transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
