GeForce RTX 4070 Ti vs Radeon Pro Duo

Intro

Compare those specs to the Radeon Pro Duo, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The HBM RAM works at a frequency of 500 MHz on this particular model. It features 4096 SPUs along with 256 Texture Address Units and 64 ROPs.

Radeon Pro Duo		512000 Mtexels/sec
	Difference: 42400 (8%)

Pixel Rate

The GeForce RTX 4070 Ti will be much (about 44%) better at anti-aliasing than the Radeon Pro Duo, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 56800 (44%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
