GeForce RTX 3070 Ti vs Radeon HD 3850 1GB

Intro

Compare those specifications to the Radeon HD 3850 1GB, which uses a 55 nm design. AMD has set the core frequency at 668 MHz. The GDDR3 memory works at a speed of 828 MHz on this particular model. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 ROPs.

	Difference: 215 Watts (287%)

Memory Bandwidth

In theory, the GeForce RTX 3070 Ti will be 1075% faster than the Radeon HD 3850 1GB overall, because of its higher data rate. (explain)

GeForce RTX 3070 Ti		622899 MB/sec
Radeon HD 3850 1GB		52992 MB/sec
	Difference: 569907 (1075%)

Texel Rate

The GeForce RTX 3070 Ti should be quite a bit (more or less 2729%) more effective at texture filtering than the Radeon HD 3850 1GB. (explain)

GeForce RTX 3070 Ti		302400 Mtexels/sec
Radeon HD 3850 1GB		10688 Mtexels/sec
	Difference: 291712 (2729%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 3070 Ti is the winner, by a large margin. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
Radeon HD 3850 1GB		10688 Mpixels/sec
	Difference: 140512 (1315%)

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 largest amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
