GeForce GTX 1630 vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which features a core clock speed of 1100 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Radeon R9 M385X		96000 MB/sec
	Difference: 2304 (2%)

Texel Rate

The Radeon R9 M385X will be just a bit (approximately 11%) faster with regards to AF than the GeForce GTX 1630. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1630 is a better choice, by far. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If 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, 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 clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
