GeForce 9400 GT 256MB vs Radeon R7 M360

Intro

Compare that to the Radeon R7 M360, which features a core clock frequency of 1125 MHz and a DDR3 memory speed of 1000 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M360 should in theory 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 will be much (more or less 514%) more effective at AF 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 is quite a bit (approximately 309%) more effective at anti-aliasing than the GeForce 9400 GT 256MB, and should be capable of handling higher screen resolutions without slowing down too much. (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: Bandwidth is the max amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 are applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling 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 write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
