GeForce GTX 1630 vs Radeon HD 5970

Intro

Compare all that to the Radeon HD 5970, which uses a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this card. It features 1600 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

GeForce GTX 1630		55680 Mtexels/sec
	Difference: 176320 (317%)

Pixel Rate

The Radeon HD 5970 is quite a bit (about 233%) better at full screen anti-aliasing than the GeForce GTX 1630, and also will be capable of handling higher resolutions more effectively. (explain)

Radeon HD 5970		92800 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 64960 (233%)

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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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