GeForce GTX 650 vs Radeon R9 M365X

Intro

The GeForce GTX 650 uses a 28 nm design. nVidia has set the core frequency at 1058 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this particular card. It features 384 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M365X, which uses a 28 nm design. AMD has set the core frequency at 925 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 650 80000 MB/sec
Radeon R9 M365X 72000 MB/sec
Difference: 8000 (11%)

Texel Rate

The Radeon R9 M365X will be a bit (about 9%) better at texture filtering than the GeForce GTX 650. (explain)

Radeon R9 M365X 37000 Mtexels/sec
GeForce GTX 650 33856 Mtexels/sec
Difference: 3144 (9%)

Pixel Rate

The GeForce GTX 650 will be a little bit (more or less 14%) more effective at FSAA than the Radeon R9 M365X, and will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 650 16928 Mpixels/sec
Radeon R9 M365X 14800 Mpixels/sec
Difference: 2128 (14%)

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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
