GeForce RTX 4070 Ti vs Radeon Pro Duo

Intro

Compare that to the Radeon Pro Duo, which has core speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM memory. 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

In theory, the Radeon Pro Duo is 98% faster than the GeForce RTX 4070 Ti overall, because of its greater data rate. (explain)

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

Texel Rate

The GeForce RTX 4070 Ti will be a small bit (approximately 8%) better 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 running with lots of anti-aliasing is important to you, then the GeForce RTX 4070 Ti is a better choice, by far. (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 maximum amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
