GeForce GTX 1630 vs Radeon R9 280X

Intro

Compare all of that to the Radeon R9 280X, which uses a 28 nm design. AMD has set the core speed at 850 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this card. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
Radeon R9 280X		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 280X will be 193% quicker than the GeForce GTX 1630 overall, due to its greater bandwidth. (explain)

Radeon R9 280X		288000 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 189696 (193%)

Texel Rate

The Radeon R9 280X will be quite a bit (more or less 95%) faster with regards to texture filtering than the GeForce GTX 1630. (explain)

Radeon R9 280X		108800 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 53120 (95%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1630 is the winner, but only just. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon R9 280X		27200 Mpixels/sec
	Difference: 640 (2%)

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 largest amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
