	Difference: 569907 (1075%)

Texel Rate

The GeForce RTX 3070 Ti will be quite a bit (more or less 2729%) better at texture filtering than the Radeon HD 3850 512MB. (explain)

GeForce RTX 3070 Ti		302400 Mtexels/sec
Radeon HD 3850 512MB		10688 Mtexels/sec
	Difference: 291712 (2729%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 3070 Ti is the winner, and very much so. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
Radeon HD 3850 512MB		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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
