GeForce RTX 2080 SUPER vs Radeon R5 M230

Intro

Compare those specs to the Radeon R5 M230, which comes with a core clock speed of 780 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It is made up of 320 SPUs, 20 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER should perform a lot faster than the Radeon R5 M230 in general. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 491904 (3074%)

Texel Rate

The GeForce RTX 2080 SUPER is much (more or less 1931%) better at texture filtering than the Radeon R5 M230. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 301200 (1931%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is a better choice, by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 102480 (3285%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at 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 chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
