GeForce RTX 3060 Ti vs Radeon HD 5870

Intro

Compare that to the Radeon HD 5870, which comes with clock speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 RAM. It features 1600(320x5) SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

Radeon HD 5870		188 Watts
GeForce RTX 3060 Ti		200 Watts
	Difference: 12 Watts (6%)

Memory Bandwidth

Performance-wise, the Radeon HD 5870 should in theory be a small bit superior to the GeForce RTX 3060 Ti overall. (explain)

Radeon HD 5870		153600 MB/sec
GeForce RTX 3060 Ti		(Unknown) MB/sec
	Difference: 153600 (-100%)

Texel Rate

The GeForce RTX 3060 Ti will be quite a bit (about 215%) faster with regards to AF than the Radeon HD 5870. (explain)

GeForce RTX 3060 Ti		214320 Mtexels/sec
Radeon HD 5870		68000 Mtexels/sec
	Difference: 146320 (215%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3060 Ti is a better choice, and very much so. (explain)

GeForce RTX 3060 Ti		112800 Mpixels/sec
Radeon HD 5870		27200 Mpixels/sec
	Difference: 85600 (315%)

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 maximum amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core clock 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 that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
