GeForce GTX 1630 vs Radeon R9 280

Intro

Compare all that to the Radeon R9 280, which makes use of a 28 nm design. AMD has set the core speed at 933 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this model. It features 1792 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 1630		98304 MB/sec
	Difference: 141696 (144%)

Texel Rate

The Radeon R9 280 is much (more or less 88%) faster with regards to AF than the GeForce GTX 1630. (explain)

Radeon R9 280		104496 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 48816 (88%)

Pixel Rate

The Radeon R9 280 should be a bit (about 7%) more effective at FSAA than the GeForce GTX 1630, and will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 280		29856 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 2016 (7%)

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 max amount of information (measured in megabytes per second) that can be transported 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 RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock 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 output 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 ability to get to the maximum fill rate.
