GeForce GTX 1630 vs Radeon R5 M255

Intro

Compare that to the Radeon R5 M255, which features core speeds of 940 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1630 is 514% quicker than the Radeon R5 M255 overall, due to its higher data rate. (explain)

GeForce GTX 1630		98304 MB/sec
Radeon R5 M255		16000 MB/sec
	Difference: 82304 (514%)

Texel Rate

The GeForce GTX 1630 is much (about 196%) more effective at texture filtering than the Radeon R5 M255. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon R5 M255		18800 Mtexels/sec
	Difference: 36880 (196%)

Pixel Rate

The GeForce GTX 1630 should be a lot (about 270%) more effective at FSAA than the Radeon R5 M255, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon R5 M255		7520 Mpixels/sec
	Difference: 20320 (270%)

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 data (counted in MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, 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 number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
