GeForce 9400 GT 256MB vs Radeon R7 M360

Intro

Compare those specifications to the Radeon R7 M360, which comes with GPU core speed of 1125 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also is made up of 384 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M360 should perform quite a bit faster than the GeForce 9400 GT 256MB overall. (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 much (approximately 514%) more effective at 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

The Radeon R7 M360 should be a lot (about 309%) more effective at full screen anti-aliasing than the GeForce 9400 GT 256MB, and also able to handle higher resolutions while still performing well. (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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at 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 record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
