GeForce GTX 1630 vs Radeon R9 M290X

Intro

Compare those specs to the Radeon R9 M290X, which makes use of a 28 nm design. AMD has set the core speed at 850 MHz. The GDDR5 RAM is set to run at a speed of 1200 MHz on this card. It features 1280 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 1630		55680 Mtexels/sec
	Difference: 12320 (22%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1630 is superior to the Radeon R9 M290X, though not by far. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon R9 M290X		27200 Mpixels/sec
	Difference: 640 (2%)

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 across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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 number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
