GeForce GTX 965M vs Radeon R7 M260X
Intro
The GeForce GTX 965M has a GPU clock speed of 944 MHz, and the 2048 MB of GDDR5 memory runs at 1000 MHz through a 128-bit bus. It also is made up of 1024 Stream Processors, 64 Texture Address Units, and 32 Raster Operation Units.Compare all of that to the Radeon R7 M260X, which features clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Memory Bandwidth
Both cards have exactly the same memory bandwidth, so in theory they should have the same performance. (explain)
Texel Rate
The GeForce GTX 965M is much (about 205%) faster with regards to AF than the Radeon R7 M260X. (explain)| GeForce GTX 965M |
|
60416 Mtexels/sec |
| Radeon R7 M260X |
|
19800 Mtexels/sec |

Pixel Rate
If using a high resolution is important to you, then the GeForce GTX 965M is the winner, by a large margin. (explain)| GeForce GTX 965M |

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
