AMD Radeon Pro Duo vs NVIDIA RTX A2000 12 GB Comparison

The AMD Radeon Pro Duo and NVIDIA RTX A2000 12 GB represent two very different eras of workstation graphics. The data shows a single head-to-head benchmark result, and it is not close: the RTX A2000 12 GB delivers a Geekbench OpenCL score of 66,998, while the Radeon Pro Duo manages 35,860. That is a 46.5% deficit for the older AMD card, placing it firmly behind in raw compute throughput as measured by this test.

Head-to-Head Benchmarks

The only direct comparison available is the Geekbench OpenCL test, and the outcome is decisive. The NVIDIA RTX A2000 12 GB scores 66,998, which is nearly double the Radeon Pro Duo’s 35,860. The deltaPct of -46.5% indicates that the Radeon Pro Duo is performing at roughly half the level of the RTX A2000 in this workload. This is a massive margin, not a marginal victory.

To contextualize the Radeon Pro Duo’s score, its nearest rivals in the database include the NVIDIA Quadro GV100 (35,520, just 1% behind), the NVIDIA GeForce RTX 5070 Ti Mobile (35,435, 1.2% ahead), and the NVIDIA T1000 (36,289, 1.2% ahead of the Pro Duo). This places the Pro Duo in a performance tier that is competitive with those cards, but the RTX A2000 is in a completely different league, sitting alongside the NVIDIA TITAN V (34,355, 0.6% behind) and the AMD Radeon RX 480 (33,997, 0.5% behind). The RTX A2000’s score is so high that it outpaces its own nearest rivals by a wide margin, even though its deltaPct against them is small (within 0.6%).

The RTX A2000 also has a second benchmark result in its profile: a 3DMark Steel Nomad DX12 score of 1,309. The Radeon Pro Duo has no corresponding 3DMark result, so no direct comparison is possible on that test. However, the presence of this DX12 score highlights a key difference in testing coverage: the RTX A2000 has been validated in a modern DirectX 12 Ultimate workload, while the Pro Duo’s data is limited to OpenCL.

Where Each One Wins

Based on the benchmark data, the NVIDIA RTX A2000 12 GB wins the only head-to-head contest, and it wins by a substantial margin. In Geekbench OpenCL, it is 46.5% faster than the Radeon Pro Duo. This makes the RTX A2000 the clear choice for any workload that relies heavily on OpenCL compute, such as certain scientific simulations, image processing, or data analytics tasks.

The Radeon Pro Duo, despite its loss, is not without merit in specific contexts. Its 35,860 OpenCL score is within 1.2% of the NVIDIA T1000 and 1.8% of the AMD Radeon RX 5300M, meaning it is comparable to those mid-range cards. For users who already own a Pro Duo or need a card that matches that specific performance level, it remains a functional option. However, the data does not show any benchmark where the Pro Duo wins outright.

The RTX A2000’s wins extend beyond raw compute. Its 3DMark Steel Nomad DX12 score of 1,309 indicates it can handle modern gaming and DirectX 12 Ultimate workloads, a category in which the Pro Duo has no recorded result. If a user needs a card that can do both compute and contemporary graphics API tasks, the RTX A2000 is the only one of the two with evidence to support that capability.

Architecture Differences

The architectural gap between these two cards is vast, reflecting their release dates. The AMD Radeon Pro Duo is built on the GCN 3.0 architecture, codenamed “Capsaicin,” and uses a 28 nm process from TSMC. It packs 8,900 million transistors on a 596 mm² die, resulting in a transistor density of 14.9M / mm². This is a large, power-hungry chip designed for compute-heavy workloads of its era.

In contrast, the NVIDIA RTX A2000 12 GB uses the Ampere architecture with the GA106 chip, manufactured on Samsung’s 8 nm process. It contains 12,000 million transistors on a much smaller 276 mm² die, achieving a transistor density of 43.5M / mm². This is nearly three times the density of the Pro Duo, showcasing the manufacturing advancements between 2016 and 2021.

Memory architecture is another major differentiator. The Pro Duo uses 4 GB of HBM memory on a 4096-bit bus, delivering 512.0 GB/s of bandwidth. The RTX A2000 uses 12 GB of GDDR6 on a 192-bit bus, providing 288.0 GB/s. While the Pro Duo has higher bandwidth, the RTX A2000 has three times the capacity, which is often more important for modern workloads that need to hold large datasets.

The RTX A2000 also brings features the Pro Duo lacks entirely: 26 RT cores and 104 tensor cores. The Pro Duo has no such hardware, meaning it cannot accelerate ray tracing or AI-based tensor operations. The RTX A2000’s API support also reflects its newer architecture, with DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the Pro Duo is limited to DirectX 12 (12_0) and Vulkan 1.2.170.

Specification Differences

The specification sheets reveal several clear differences between the two cards. The most obvious is memory: the Pro Duo has 4 GB of HBM, while the RTX A2000 has 12 GB of GDDR6. The bus widths differ dramatically (4096-bit vs 192-bit), but the RTX A2000’s effective memory speed is higher at 12 Gbps compared to the Pro Duo’s 1000 Mbps effective.

Clock speeds are reported differently. The Pro Duo lists no base or boost clock, only a memory clock of 500 MHz. The RTX A2000 has a base clock of 562 MHz and a boost clock of 1200 MHz. In terms of raw compute, the Pro Duo claims 8.192 TFLOPS for both FP32 and FP16, while the RTX A2000 claims 7.987 TFLOPS for both. The Pro Duo is slightly ahead on paper, but the benchmark results show the RTX A2000 performs much better in practice.

Power requirements are a stark contrast. The Pro Duo is rated at 350 W TDP with three 8-pin power connectors and a suggested 750 W PSU. The RTX A2000 is rated at 70 W TDP, requires no external power connectors, and only needs a 250 W PSU. This makes the RTX A2000 far easier to install in compact systems or those with limited power budgets.

Physical dimensions also differ: the Pro Duo is 277 mm long and 111 mm tall, while the RTX A2000 is 167 mm long and 69 mm tall. Both are dual-slot cards, but the RTX A2000 is much smaller. The Pro Duo offers 1x HDMI 1.4a and 3x DisplayPort 1.2, while the RTX A2000 provides 4x mini-DisplayPort 1.4a. The RTX A2000 also uses PCIe 4.0 x16, whereas the Pro Duo is limited to PCIe 3.0 x16.

The Verdict

The data is unambiguous: the NVIDIA RTX A2000 12 GB is the superior card in every measurable way. It is 46.5% faster in OpenCL, has three times the memory capacity, supports modern APIs like DirectX 12 Ultimate and Vulkan 1.4, and does so at a fraction of the power draw (70 W vs 350 W). The RTX A2000 also includes RT and tensor cores, which the Pro Duo lacks entirely, making it a future-proof choice for ray tracing and AI workloads.

The AMD Radeon Pro Duo’s only advantage is theoretical: its FP32 rating of 8.192 TFLOPS is marginally higher than the RTX A2000’s 7.987 TFLOPS, and its memory bandwidth of 512.0 GB/s is higher. However, these paper specs do not translate to real-world performance, as the benchmark results show. The Pro Duo also has a higher transistor count on a larger die, but this results in higher power consumption and heat, not better performance.

For a builder choosing between these two, the RTX A2000 is the obvious pick. It offers better performance, more memory, newer features, and a much easier installation experience due to its low power requirements and compact size. The Pro Duo is a relic of an older era, and while its OpenCL score is respectable for its time, it cannot keep up with modern Ampere architecture. Unless a specific legacy workload requires the Pro Duo’s exact HBM configuration, the RTX A2000 is the only sensible choice based on the available data.
