GeForce RTX 2070 Super vs Radeon R9 380 4G

Intro

Compare all of that to the Radeon R9 380 4G, which has a core clock speed of 970 MHz and a GDDR5 memory speed of 1425 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Radeon R9 380 4G		108640 Mtexels/sec
	Difference: 148160 (136%)

Pixel Rate

The GeForce RTX 2070 Super should be quite a bit (more or less 231%) faster with regards to FSAA than the Radeon R9 380 4G, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Radeon R9 380 4G		31040 Mpixels/sec
	Difference: 71680 (231%)

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 max amount of data (measured in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
