GeForce GTX 1630 vs Radeon R7 250X

Intro

Compare all of that to the Radeon R7 250X, which uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
Radeon R7 250X		95 Watts
	Difference: 20 Watts (27%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1630 will be 37% faster than the Radeon R7 250X in general, because of its higher bandwidth. (explain)

GeForce GTX 1630		98304 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 26304 (37%)

Texel Rate

The GeForce GTX 1630 is a lot (about 39%) more effective at anisotropic filtering than the Radeon R7 250X. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 15680 (39%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1630 is superior to the Radeon R7 250X, by far. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon R7 250X		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 maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high 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 amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
