GeForce GTX 1630 vs Radeon R7 250

Intro

Compare those specifications to the Radeon R7 250, which features GPU core speed of 1000 MHz, and 1024 MB of GDDR5 RAM running at 1150 MHz through a 128-bit bus. It also is comprised of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1630 is 34% quicker than the Radeon R7 250 in general, due to its higher bandwidth. (explain)

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

Texel Rate

The GeForce GTX 1630 will be much (about 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 should be a lot (more or less 248%) more effective at full screen anti-aliasing than the Radeon R7 250, and also should be able to handle higher resolutions without losing too much performance. (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 max amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a 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 clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
