Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
Radeon HD 4850 X2 1GB		250 Watts
	Difference: 220 Watts (733%)

Memory Bandwidth

In theory, the Radeon HD 4850 X2 1GB is 159% faster than the GeForce GT 1030 in general, because of its higher data rate. (explain)

Radeon HD 4850 X2 1GB		127104 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 77952 (159%)

Texel Rate

The Radeon HD 4850 X2 1GB should be much (more or less 24%) better at AF than the GeForce GT 1030. (explain)

Radeon HD 4850 X2 1GB		50000 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 9520 (24%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GT 1030 is a better choice, but not by far. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 4850 X2 1GB		20000 Mpixels/sec
	Difference: 240 (1%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the interface 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 better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to 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 memory bandwidth is, the lower the ability to get to the max fill rate.
