The Verdict

The data points to a single conclusion: choose the NVIDIA GeForce RTX 4070 for almost any purpose. The 331.8% lead in Geekbench OpenCL is not a marginal advantage — it is a generational leap. The RTX 4070 also offers three times the memory capacity (12 GB vs 4 GB), a smaller physical footprint (240 mm vs 277 mm length), and vastly lower power draw (200 W vs 350 W TDP).

The Radeon Pro Duo's only advantage is its 512.0 GB/s memory bandwidth, which edges out the RTX 4070's 504.2 GB/s by roughly 1.5%. However, this narrow lead is meaningless given the RTX 4070's overwhelming compute superiority and modern feature set. The RTX 4070 supports ray tracing cores (46), tensor cores (184), and DirectX 12 Ultimate, while the Radeon Pro Duo has none of these features.

For gaming, content creation, or professional compute, the RTX 4070 is the clear winner. The Radeon Pro Duo should only be considered for legacy applications that specifically require GCN 3.0 architecture quirks or dual-GPU setups — and even then, its 4 GB memory limit makes it impractical for modern workloads.

Head-to-Head Benchmarks

The only direct comparison available is the Geekbench OpenCL test, and it is not close. The RTX 4070 scored 154,858 points, while the Radeon Pro Duo managed 35,860. This 331.8% deltaPct means the RTX 4070 delivers roughly 4.3 times the compute throughput of the older AMD card. This is the single largest margin in the entire comparison, and it reflects the fundamental architectural gap between Ada Lovelace and GCN 3.0.

Interestingly, the nearest rivals data shows both cards occupy similar average performance territory. The RTX 4070's average score of 37,648 sits just 0.1% above the NVIDIA Tesla P4 (37,628) and 1.3% above the AMD Radeon PRO W6400 (37,157). The Radeon Pro Duo's average of 35,860 is 1% above the NVIDIA Quadro GV100 (35,520) but 1.8% below the AMD Radeon RX 5300M (36,529). This suggests that while the RTX 4070 and Radeon Pro Duo land in similar overall performance brackets, the RTX 4070 achieves this with modern efficiency while the Radeon Pro Duo relies on raw dual-GPU muscle.

The RTX 4070 also has a much richer benchmark portfolio, with scores across 3DMark Steel Nomad (3,854), Geekbench Vulkan (174,152), Passmark G3D (26,927), and Passmark GPU Compute (14,720). The Radeon Pro Duo only has a single Geekbench OpenCL result, making it impossible to assess its performance in DirectX or Vulkan workloads from the available data.

Specification Differences

The specifications tell a story of two completely different design philosophies. The RTX 4070 uses a 5 nm process at TSMC, while the Radeon Pro Duo relies on a 28 nm process at the same foundry. This process gap explains the massive transistor density difference: 121.8M per mm² versus 14.9M per mm².

Clock speeds are starkly different. The RTX 4070 has a base clock of 1920 MHz and a boost clock of 2475 MHz, while the Radeon Pro Duo has no listed base or boost clocks. Memory clocks also differ significantly: the RTX 4070 runs its GDDR6X at 1313 MHz (21 Gbps effective), while the Radeon Pro Duo's HBM runs at just 500 MHz (1000 Mbps effective).

The RTX 4070 has more shading units (5888 vs 4096) but fewer texture mapping units (184 vs 256). Both have 64 ROPs. The RTX 4070 features 46 ray tracing cores and 184 tensor cores, while the Radeon Pro Duo has none of either. Pixel rate favors the RTX 4070 at 158.4 GPixel/s versus 64.00 GPixel/s, and texture rate is 455.4 GTexel/s versus 256.0 GTexel/s.

Compute output is decisively in the RTX 4070's favor: 29.15 TFLOPS FP32 and FP16 versus 8.192 TFLOPS for both on the Radeon Pro Duo. The RTX 4070 also supports PCIe 4.0 x16, while the Radeon Pro Duo is limited to PCIe 3.0 x16. Display outputs differ too — the RTX 4070 has 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the Radeon Pro Duo has 1x HDMI 1.4a and 3x DisplayPort 1.2.

Architecture Differences

The architectural gap is the defining factor in this comparison. The RTX 4070 uses the AD104 chip based on Ada Lovelace architecture, which is designed for high efficiency and modern features. The Radeon Pro Duo uses the Capsaicin chip based on GCN 3.0, an older architecture that prioritized raw throughput over efficiency.

The RTX 4070's 5 nm process allows for 35,800 million transistors on a 294 mm² die, while the Radeon Pro Duo's 28 nm process limits it to 8,900 million transistors on a larger 596 mm² die. This is why the RTX 4070 achieves 29.15 TFLOPS FP32 with a 200 W TDP, while the Radeon Pro Duo only reaches 8.192 TFLOPS with a 350 W TDP.

The RTX 4070 includes dedicated ray tracing hardware (46 RT cores) and tensor cores (184) for AI workloads, features completely absent from the Radeon Pro Duo. The memory architectures also differ fundamentally: the RTX 4070 uses 12 GB of GDDR6X on a 192-bit bus, while the Radeon Pro Duo uses 4 GB of HBM on a 4096-bit bus. The HBM approach gives the Radeon Pro Duo slightly higher bandwidth (512.0 GB/s vs 504.2 GB/s) but at the cost of capacity and complexity.

The Radeon Pro Duo's dual-GPU nature is implied by its dual-slot design and three 8-pin power connectors, but the architecture itself is GCN 3.0, which lacks modern features like mesh shaders and hardware-accelerated ray tracing. The RTX 4070 supports DirectX 12 Ultimate (12_2), while the Radeon Pro Duo only supports DirectX 12 (12_0).

Where Each One Wins

The RTX 4070 wins in almost every measurable category. It dominates compute performance with 29.15 TFLOPS FP32 versus 8.192 TFLOPS. It wins on pixel rate (158.4 GPixel/s vs 64.00 GPixel/s) and texture rate (455.4 GTexel/s vs 256.0 GTexel/s). It has more memory capacity (12 GB vs 4 GB), newer API support, and a smaller physical footprint (240 mm vs 277 mm length).

The Radeon Pro Duo's sole specification victory is memory bandwidth: 512.0 GB/s versus 504.2 GB/s. This narrow 1.5% advantage gives it a theoretical edge in bandwidth-bound workloads like large data transfers or certain compute kernels. However, the 4 GB memory capacity severely limits what can actually be stored and processed, making this advantage largely theoretical.

For gaming, the RTX 4070 is the only viable choice. Its 5888 shading units, 184 TMUs, and 46 RT cores provide the horsepower needed for modern titles, and its DirectX 12 Ultimate support ensures compatibility with the latest rendering techniques. The Radeon Pro Duo's GCN 3.0 architecture and DirectX 12 (12_0) support place it firmly in the past.

For professional compute, the RTX 4070's tensor cores and higher FP32 throughput make it suitable for AI inference and machine learning tasks. The Radeon Pro Duo, despite its "Pro" branding, lacks these specialized units and offers significantly lower compute density. The RTX 4070 also consumes 150 W less power (200 W vs 350 W TDP), making it easier to cool and cheaper to run in multi-GPU configurations.

In short, the RTX 4070 is the superior card for every workload where these two overlap. The Radeon Pro Duo's only niche is legacy software that specifically requires GCN 3.0 behavior, and even then, its 4 GB memory limit makes it a poor choice for modern datasets. The data is unambiguous: the RTX 4070 wins this comparison by a wide margin.
