GeForce 9400 GT 256MB vs Radeon R7 M260

Intro

The GeForce 9400 GT 256MB has a GPU clock speed of 550 MHz, and the 256 MB of GDDR2 RAM runs at 400 MHz through a 128-bit bus. It also features 16 Stream Processors, 8 TAUs, and 4 ROPs.

Compare those specs to the Radeon R7 M260, which features GPU core speed of 715 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Performance-wise, the Radeon R7 M260 should in theory be much better than the GeForce 9400 GT 256MB overall. (explain)

Radeon R7 M260 16000 MB/sec
GeForce 9400 GT 256MB 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R7 M260 should be quite a bit (more or less 290%) better at AF than the GeForce 9400 GT 256MB. (explain)

Radeon R7 M260 17160 Mtexels/sec
GeForce 9400 GT 256MB 4400 Mtexels/sec
Difference: 12760 (290%)

Pixel Rate

The Radeon R7 M260 should be quite a bit (more or less 160%) more effective at AA than the GeForce 9400 GT 256MB, and also should be capable of handling higher resolutions while still performing well. (explain)

Radeon R7 M260 5720 Mpixels/sec
GeForce 9400 GT 256MB 2200 Mpixels/sec
Difference: 3520 (160%)

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 max amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 can be processed per 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 this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
