GeForce GTX 1630 vs Radeon R9 M385X

Intro

The GeForce GTX 1630 makes use of a 12 nm design. nVidia has clocked the core speed at 1740 MHz. The GDDR6 RAM runs at a frequency of 1500 MHz on this specific model. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.

Compare that to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 RAM runs at a speed of 1500 MHz on this model. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

The GeForce GTX 1630 should theoretically perform a bit faster than the Radeon R9 M385X overall. (explain)

GeForce GTX 1630 98304 MB/sec
Radeon R9 M385X 96000 MB/sec
Difference: 2304 (2%)

Texel Rate

The Radeon R9 M385X will be a little bit (about 11%) more effective at anisotropic filtering than the GeForce GTX 1630. (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce GTX 1630 55680 Mtexels/sec
Difference: 5920 (11%)

Pixel Rate

The GeForce GTX 1630 should be much (more or less 58%) more effective at AA than the Radeon R9 M385X, and also capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 1630 27840 Mpixels/sec
Radeon R9 M385X 17600 Mpixels/sec
Difference: 10240 (58%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (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 card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
