GeForce RTX 3080 12 GB vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which makes use of a 28 nm design. AMD has clocked the core speed at 725 MHz. The DDR3 memory runs at a frequency of 1000 MHz on this particular card. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce RTX 3080 12 GB should be 2820% quicker than the Radeon R7 M265 in general, because of its greater data rate. (explain)

GeForce RTX 3080 12 GB		934298 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 902298 (2820%)

Texel Rate

The GeForce RTX 3080 12 GB will be much (more or less 1928%) better at texture filtering than the Radeon R7 M265. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 335400 (1928%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3080 12 GB is superior to the Radeon R7 M265, and very much so. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 135320 (2333%)

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 within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
