GeForce GTX 1630 vs Radeon R9 M380

Intro

Compare all that to the Radeon R9 M380, which comes with core speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 1630 should theoretically be a small bit better than the Radeon R9 M380 overall. (explain)

GeForce GTX 1630		98304 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 2304 (2%)

Texel Rate

The GeForce GTX 1630 is quite a bit (about 39%) faster with regards to texture filtering than the Radeon R9 M380. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 15680 (39%)

Pixel Rate

The GeForce GTX 1630 is quite a bit (more or less 74%) more effective at anti-aliasing than the Radeon R9 M380, and should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 11840 (74%)

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 max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at 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 chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
