GeForce GT 1030 vs Radeon RX 460

Intro

Compare all of that to the Radeon RX 460, which features a core clock frequency of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit bus, and uses a 14 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Texel Rate

The Radeon RX 460 is a lot (approximately 51%) more effective at texture filtering than the GeForce GT 1030. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 20560 (51%)

Pixel Rate

The GeForce GT 1030 will be a bit (about 16%) faster with regards to full screen anti-aliasing than the Radeon RX 460, and also will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 2800 (16%)

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 max amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
