GeForce GTX 1630 vs Radeon R7 250

Intro

Compare all that to the Radeon R7 250, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory runs at a frequency of 1150 MHz on this specific model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Radeon R7 250		65 Watts
GeForce GTX 1630		75 Watts
	Difference: 10 Watts (15%)

Memory Bandwidth

The GeForce GTX 1630, in theory, should be quite a bit faster than the Radeon R7 250 overall. (explain)

GeForce GTX 1630		98304 MB/sec
Radeon R7 250		73600 MB/sec
	Difference: 24704 (34%)

Texel Rate

The GeForce GTX 1630 should be much (approximately 132%) more effective at AF than the Radeon R7 250. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 31680 (132%)

Pixel Rate

The GeForce GTX 1630 is quite a bit (more or less 248%) better at anti-aliasing than the Radeon R7 250, and also able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 19840 (248%)

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 maximum amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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