GeForce 8400 GS 512MB vs Radeon R7 M360

Intro

Compare those specs to the Radeon R7 M360, which uses a 28 nm design. AMD has clocked the core speed at 1125 MHz. The DDR3 RAM runs at a frequency of 1000 MHz on this particular card. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 M360 should theoretically be much superior to the GeForce 8400 GS 512MB in general. (explain)

Radeon R7 M360		16000 MB/sec
GeForce 8400 GS 512MB		6400 MB/sec
	Difference: 9600 (150%)

Texel Rate

The Radeon R7 M360 is much (more or less 419%) better at texture filtering than the GeForce 8400 GS 512MB. (explain)

Radeon R7 M360		27000 Mtexels/sec
GeForce 8400 GS 512MB		5200 Mtexels/sec
	Difference: 21800 (419%)

Pixel Rate

The Radeon R7 M360 will be quite a bit (about 246%) more effective at anti-aliasing than the GeForce 8400 GS 512MB, and capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R7 M360		9000 Mpixels/sec
GeForce 8400 GS 512MB		2600 Mpixels/sec
	Difference: 6400 (246%)

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 largest amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses 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 high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. 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 potential to get to the maximum fill rate.
