GeForce RTX 2070 vs Radeon RX 480 4GB

Intro

Compare all of that to the Radeon RX 480 4GB, which uses a 14 nm design. AMD has clocked the core speed at 1120 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular card. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Radeon RX 480 4GB		150 Watts
GeForce RTX 2070		175 Watts
	Difference: 25 Watts (17%)

Memory Bandwidth

Performance-wise, the GeForce RTX 2070 should in theory be quite a bit better than the Radeon RX 480 4GB in general. (explain)

GeForce RTX 2070		458752 MB/sec
Radeon RX 480 4GB		229376 MB/sec
	Difference: 229376 (100%)

Texel Rate

The GeForce RTX 2070 is a lot (about 26%) more effective at anisotropic filtering than the Radeon RX 480 4GB. (explain)

GeForce RTX 2070		203040 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 41760 (26%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 2070 is a better choice, and very much so. (explain)

GeForce RTX 2070		90240 Mpixels/sec
Radeon RX 480 4GB		35840 Mpixels/sec
	Difference: 54400 (152%)

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: Bandwidth is the largest amount of data (counted in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses 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 are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
