GeForce RTX 4070 Ti vs Radeon R9 Nano

Intro

Compare all that to the Radeon R9 Nano, which has a clock speed of 1000 MHz and a HBM memory speed of 500 MHz. It also uses a 4096-bit memory bus, and uses a 28 nm design. It is comprised of 4096 SPUs, 256 Texture Address Units, and 64 ROPs.

Radeon R9 Nano		175 Watts
GeForce RTX 4070 Ti		285 Watts
	Difference: 110 Watts (63%)

Memory Bandwidth

In theory, the GeForce RTX 4070 Ti is 1% quicker than the Radeon R9 Nano in general, because of its greater data rate. (explain)

GeForce RTX 4070 Ti		516096 MB/sec
Radeon R9 Nano		512000 MB/sec
	Difference: 4096 (1%)

Texel Rate

The GeForce RTX 4070 Ti will be quite a bit (approximately 117%) better at anisotropic filtering than the Radeon R9 Nano. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon R9 Nano		256000 Mtexels/sec
	Difference: 298400 (117%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 4070 Ti is a better choice, by a large margin. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 120800 (189%)

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 information (counted in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses 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 number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at 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 record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
