GeForce 9400 GT 256MB vs Radeon R7 M260

Intro

The GeForce 9400 GT 256MB features a GPU core clock speed of 550 MHz, and the 256 MB of GDDR2 memory is set to run at 400 MHz through a 128-bit bus. It also features 16 SPUs, 8 TAUs, and 4 ROPs.

Compare all that to the Radeon R7 M260, which features core clock speeds of 715 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260 will be 25% quicker than the GeForce 9400 GT 256MB overall, because of its higher data rate. (explain)

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

Texel Rate

The Radeon R7 M260 is a lot (approximately 290%) better at anisotropic filtering 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 will be much (approximately 160%) more effective at anti-aliasing than the GeForce 9400 GT 256MB, and should be able to handle higher screen resolutions more effectively. (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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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