GeForce 830M vs Radeon RX 480

Intro

Compare all of that to the Radeon RX 480, which uses a 14 nm design. AMD has set the core frequency at 1120 MHz. The GDDR5 memory runs at a speed of 2000 MHz on this specific card. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M		25 Watts
Radeon RX 480		150 Watts
	Difference: 125 Watts (500%)

Memory Bandwidth

In theory, the Radeon RX 480 is 1720% faster than the GeForce 830M in general, due to its greater data rate. (explain)

Radeon RX 480		262144 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 247744 (1720%)

Texel Rate

The Radeon RX 480 should be quite a bit (more or less 880%) better at AF than the GeForce 830M. (explain)

Radeon RX 480		161280 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 144816 (880%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 480 is superior to the GeForce 830M, by far. (explain)

Radeon RX 480		35840 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 27608 (335%)

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 information (measured in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the 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 that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
