GeForce RTX 3070 Ti vs Radeon R9 Nano

Intro

Compare that to the Radeon R9 Nano, which features a core clock frequency of 1000 MHz and a HBM memory frequency of 500 MHz. It also uses a 4096-bit memory bus, and makes use of a 28 nm design. It is comprised of 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Radeon R9 Nano		256000 Mtexels/sec
	Difference: 46400 (18%)

Pixel Rate

The GeForce RTX 3070 Ti should be quite a bit (about 136%) better at AA than the Radeon R9 Nano, and will be able to handle higher resolutions while still performing well. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 87200 (136%)

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 (counted in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a 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 figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
