GeForce RTX 4070 Ti vs Radeon Pro Duo

Intro

Compare those specifications to the Radeon Pro Duo, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The HBM memory runs at a frequency of 500 MHz on this specific model. It features 4096 SPUs along with 256 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 4070 Ti		285 Watts
Radeon Pro Duo		350 Watts
	Difference: 65 Watts (23%)

Memory Bandwidth

Performance-wise, the Radeon Pro Duo should in theory be a lot superior to the GeForce RTX 4070 Ti in general. (explain)

Radeon Pro Duo		1024000 MB/sec
GeForce RTX 4070 Ti		516096 MB/sec
	Difference: 507904 (98%)

Texel Rate

The GeForce RTX 4070 Ti should be a little bit (more or less 8%) more effective at AF than the Radeon Pro Duo. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon Pro Duo		512000 Mtexels/sec
	Difference: 42400 (8%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 4070 Ti is the winner, and very much so. (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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 potential to get to the max fill rate.
