GeForce 830M vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which features core clock speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M365X should theoretically be much better than the GeForce 830M overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R9 M365X should be much (approximately 125%) better at AF than the GeForce 830M. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 20536 (125%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M365X is a better choice, by far. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 6568 (80%)

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 largest amount of data (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
