GeForce GTX 1630 vs Radeon R9 M280X

Intro

Compare that to the Radeon R9 M280X, which makes use of a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 RAM runs at a frequency of 1375 MHz on this card. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 1630, in theory, should perform just a bit faster than the Radeon R9 M280X in general. (explain)

GeForce GTX 1630		98304 MB/sec
Radeon R9 M280X		88000 MB/sec
	Difference: 10304 (12%)

Texel Rate

The GeForce GTX 1630 should be a little bit (about 10%) better at texture filtering than the Radeon R9 M280X. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon R9 M280X		50400 Mtexels/sec
	Difference: 5280 (10%)

Pixel Rate

The GeForce GTX 1630 will be quite a bit (about 93%) more effective at full screen anti-aliasing than the Radeon R9 M280X, and will be able to handle higher resolutions more effectively. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon R9 M280X		14400 Mpixels/sec
	Difference: 13440 (93%)

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 largest amount of information (in units of MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at 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 the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
