GeForce GTX 1630 vs Radeon R9 270

Intro

Compare those specifications to the Radeon R9 270, which uses a 28 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 RAM works at a frequency of 1400 MHz on this card. It features 1280 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
Radeon R9 270		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

In theory, the Radeon R9 270 should perform a lot faster than the GeForce GTX 1630 overall. (explain)

Radeon R9 270		179200 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 80896 (82%)

Texel Rate

The Radeon R9 270 should be quite a bit (approximately 29%) better at anisotropic filtering than the GeForce GTX 1630. (explain)

Radeon R9 270		72000 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 16320 (29%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 270 is a better choice, though only just barely. (explain)

Radeon R9 270		28800 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 960 (3%)

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 largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
