GeForce 9400 GT 256MB vs Radeon R7 M360

Intro

Compare that to the Radeon R7 M360, which comes with clock speeds of 1125 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M360, in theory, should be much faster than the GeForce 9400 GT 256MB in general. (explain)

Radeon R7 M360		16000 MB/sec
GeForce 9400 GT 256MB		12800 MB/sec
	Difference: 3200 (25%)

Texel Rate

The Radeon R7 M360 should be a lot (about 514%) faster with regards to anisotropic filtering than the GeForce 9400 GT 256MB. (explain)

Radeon R7 M360		27000 Mtexels/sec
GeForce 9400 GT 256MB		4400 Mtexels/sec
	Difference: 22600 (514%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 M360 is a better choice, and very much so. (explain)

Radeon R7 M360		9000 Mpixels/sec
GeForce 9400 GT 256MB		2200 Mpixels/sec
	Difference: 6800 (309%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 processed in one second. This 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 graphics 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 maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
