Specification Differences

The two GPUs differ across nearly every major specification category. The process node is the most fundamental difference: 28 nm for AMD versus 8 nm for NVIDIA. This drives the transistor count difference, with 8,900 million on the AMD side and 17,400 million on the NVIDIA side. Die size reverses this trend, with the AMD card larger at 596 mm² versus 392 mm² for NVIDIA.

Memory capacity differs by 4 GB, with the Radeon Pro Duo offering 4 GB HBM and the RTX 3070 Ti offering 8 GB GDDR6X. Bus width is dramatically different: 4096 bit for AMD versus 256 bit for NVIDIA. Bandwidth favors NVIDIA at 608.3 GB/s compared to 512.0 GB/s for AMD.

Compute unit counts show NVIDIA's advantage in shading units (6,144 vs 4,096), ROPs (96 vs 64), and RT cores (48 vs 0). However, AMD leads in texture mapping units, with 256 versus 192 for NVIDIA. Tensor cores exist only on NVIDIA, with 192 present.

Clock speeds differ as well. The AMD card lists a memory clock of 500 MHz (1000 Mbps effective), while the NVIDIA card has a base clock of 1575 MHz, boost clock of 1770 MHz, and memory clock of 1188 MHz (19 Gbps effective). The AMD card's base and boost clocks are not recorded.

Power requirements favor NVIDIA, with a 290 W TDP and 600 W suggested PSU, compared to AMD's 350 W TDP and 750 W suggested PSU. The power connector configurations differ, with AMD requiring three 8-pin connectors and NVIDIA requiring one 12-pin connector.

Bus interface and display outputs also differ. AMD uses PCIe 3.0 x16, while NVIDIA uses PCIe 4.0 x16. Display outputs are identical in count (1x HDMI, 3x DisplayPort) but differ in versions: HDMI 1.4a and DisplayPort 1.2 for AMD, versus HDMI 2.1 and DisplayPort 1.4a for NVIDIA.

Physical dimensions are similar in length, with the AMD card at 277 mm and the NVIDIA card at 267 mm, both at 111 mm or 112 mm height, and both dual-slot designs.

Head-to-Head Benchmarks

The only direct head-to-head benchmark recorded is Geekbench OpenCL. In this test, the NVIDIA GeForce RTX 3070 Ti scores 119,718, while the AMD Radeon Pro Duo scores 35,860. The delta percentage is -70%, meaning the RTX 3070 Ti outperforms the Radeon Pro Duo by 70% in this specific workload.
