GeForce GTX 1630 vs Radeon R9 M385X

Intro

The GeForce GTX 1630 features a GPU clock speed of 1740 MHz, and the 4096 MB of GDDR6 RAM runs at 1500 MHz through a 64-bit bus. It also is comprised of 512 SPUs, 32 TAUs, and 16 ROPs.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 1630 should theoretically be just 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 is a bit (approximately 11%) faster with regards to 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

If running with lots of anti-aliasing 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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
