GeForce GTX 1630 vs Radeon HD 3850 X2

Intro

Compare that to the Radeon HD 3850 X2, which features core clock speeds of 668 MHz on the GPU, and 828 MHz on the 512 MB of GDDR3 RAM. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 3850 X2 should in theory perform a little bit faster than the GeForce GTX 1630 in general. (explain)

Radeon HD 3850 X2		105984 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 7680 (8%)

Texel Rate

The GeForce GTX 1630 is much (about 160%) better at AF than the Radeon HD 3850 X2. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon HD 3850 X2		21376 Mtexels/sec
	Difference: 34304 (160%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1630 is the winner, and very much so. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon HD 3850 X2		21376 Mpixels/sec
	Difference: 6464 (30%)

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 largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once 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 number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock 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 quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
