GeForce GTX 1630 vs Radeon HD 7870 XT

Intro

Compare all of that to the Radeon HD 7870 XT, which uses a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this specific model. It features 1536 SPUs along with 96 TAUs and 32 ROPs.

GeForce GTX 1630		98304 MB/sec
	Difference: 93696 (95%)

Texel Rate

The Radeon HD 7870 XT is much (more or less 59%) better at AF than the GeForce GTX 1630. (explain)

Radeon HD 7870 XT		88800 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 33120 (59%)

Pixel Rate

The Radeon HD 7870 XT will be just a bit (more or less 6%) more effective at FSAA than the GeForce GTX 1630, and also capable of handling higher resolutions while still performing well. (explain)

Radeon HD 7870 XT		29600 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 1760 (6%)

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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, 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 the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
