GeForce GTX 280 vs GeForce RTX 2080

Intro

Compare all that to the GeForce RTX 2080, which uses a 12 nm design. nVidia has clocked the core frequency at 1515 MHz. The GDDR6 RAM runs at a speed of 1750 MHz on this particular model. It features 2944 SPUs as well as 184 Texture Address Units and 64 Rasterization Operator Units.

GeForce RTX 2080		215 Watts
GeForce GTX 280		236 Watts
	Difference: 21 Watts (10%)

Memory Bandwidth

Performance-wise, the GeForce RTX 2080 should in theory be much superior to the GeForce GTX 280 in general. (explain)

GeForce RTX 2080		458752 MB/sec
GeForce GTX 280		141696 MB/sec
	Difference: 317056 (224%)

Texel Rate

The GeForce RTX 2080 is a lot (more or less 479%) faster with regards to AF than the GeForce GTX 280. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce GTX 280		48160 Mtexels/sec
	Difference: 230600 (479%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 2080 is superior to the GeForce GTX 280, and very much so. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce GTX 280		19264 Mpixels/sec
	Difference: 77696 (403%)

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 information (in units of MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling 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 graphics card can possibly write to the 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 the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
