GeForce GTX 1630 vs Radeon R9 295X2

Intro

Compare all that to the Radeon R9 295X2, which makes use of a 28 nm design. AMD has set the core speed at 1018 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this specific model. It features 2816 SPUs along with 176 Texture Address Units and 64 ROPs.

GeForce GTX 1630		55680 Mtexels/sec
	Difference: 302656 (544%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 295X2 is a better choice, by far. (explain)

Radeon R9 295X2		130304 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 102464 (368%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 number of pixels that the graphics 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 amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
