GeForce GTX 1630 vs Radeon R9 M265X

Intro

Compare all that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has clocked the core speed at 575 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 1630 should be 37% quicker than the Radeon R9 M265X overall, due to its greater data rate. (explain)

GeForce GTX 1630		98304 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 26304 (37%)

Texel Rate

The GeForce GTX 1630 should be quite a bit (approximately 142%) more effective at anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 32680 (142%)

Pixel Rate

The GeForce GTX 1630 should be a lot (about 203%) better at full screen anti-aliasing than the Radeon R9 M265X, and also should be able to handle higher screen resolutions better. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 18640 (203%)

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 largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 are applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
