GeForce 830M vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which has clock speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M375X should perform a lot faster than the GeForce 830M in general. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R9 M375X should be much (approximately 147%) faster with regards to AF than the GeForce 830M. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 24136 (147%)

Pixel Rate

The Radeon R9 M375X will be quite a bit (about 97%) more effective at FSAA than the GeForce 830M, and also capable of handling higher screen resolutions better. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 8008 (97%)

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 transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core 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 also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
