GeForce GTX 1630 vs Radeon R9 Nano

Intro

Compare those specs to the Radeon R9 Nano, which features clock speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM memory. It features 4096 SPUs as well as 256 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
Radeon R9 Nano		175 Watts
	Difference: 100 Watts (133%)

Memory Bandwidth

In theory, the Radeon R9 Nano should perform quite a bit faster than the GeForce GTX 1630 in general. (explain)

Radeon R9 Nano		512000 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 413696 (421%)

Texel Rate

The Radeon R9 Nano should be a lot (approximately 360%) better at texture filtering than the GeForce GTX 1630. (explain)

Radeon R9 Nano		256000 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 200320 (360%)

Pixel Rate

The Radeon R9 Nano is much (more or less 130%) more effective at anti-aliasing than the GeForce GTX 1630, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 Nano		64000 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 36160 (130%)

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 (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
