GeForce GTX 1630 vs Radeon R9 M280X

Intro

Compare all that to the Radeon R9 M280X, which uses a 28 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 memory runs at a speed of 1375 MHz on this particular model. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the GeForce GTX 1630 should theoretically be a small bit superior to 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 is a bit (more or less 10%) more effective at AF than the Radeon R9 M280X. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1630 is superior to the Radeon R9 M280X, by far. (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 max amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
