Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 M360 should in theory be a lot better 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 will be quite a bit (approximately 514%) more effective at texture 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

The Radeon R7 M360 will be a lot (about 309%) faster with regards to full screen anti-aliasing than the GeForce 9400 GT 256MB, and also will be able to handle higher screen resolutions without losing too much performance. (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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
