AMD Radeon Pro Vega II Duo vs NVIDIA RTX 4000 Ada Generation Comparison

The NVIDIA RTX 4000 Ada Generation and AMD Radeon Pro Vega II Duo represent two very different eras of workstation graphics. The RTX 4000 Ada is a modern, efficient single-slot card built on TSMC’s 5 nm process, while the Vega II Duo is a legacy, quad-slot dual-GPU Mac-oriented card on a 7 nm process. Benchmark data from Geekbench shows a clear overall winner, but the specifics of memory, architecture, and platform support tell a more nuanced story for potential buyers.

Head-to-Head Benchmarks

In the two shared benchmark tests, the NVIDIA RTX 4000 Ada Generation wins decisively. In Geekbench OpenCL, the RTX 4000 Ada scores 146,593 against the Vega II Duo’s 98,432, a delta of 48.9% in NVIDIA’s favor. That is not a marginal lead; it is a massive performance gap that places the RTX 4000 Ada in a different performance tier for compute workloads that rely on OpenCL. The Vega II Duo’s best result in this comparison comes in Geekbench Vulkan, where it scores 99,296, but the RTX 4000 Ada still beats it with a score of 123,842, a 24.7% advantage. Neither test shows the AMD card winning, and the head-to-head tally stands at 2 wins for NVIDIA and 0 for AMD.

Looking at average benchmark scores reinforces this picture. The RTX 4000 Ada has an average benchmark score of 135,218, while the Vega II Duo averages 106,750. That is a difference of roughly 26.7% in favor of NVIDIA. The RTX 4000 Ada also sits at the 95th percentile of all GPUs, compared to the Vega II Duo’s 94th percentile, though that single-point gap undersells the raw score difference. When you examine the nearest rivals, the RTX 4000 Ada’s closest competitor is the NVIDIA A10M with an average score of 135,230 (delta 0%), followed by the AMD Radeon PRO W6800 at 135,396 (delta -0.1%). The Vega II Duo, by contrast, is closest to the AMD Radeon Pro W6600X at 107,342 (delta -0.6%) and the single-GPU AMD Radeon Pro Vega II at 109,617 (delta -2.6%). Notably, the Vega II Duo outperforms the NVIDIA Quadro RTX 6000 by 4.8%, showing it still has some competitive life against older NVIDIA pro cards, but it is far behind the modern RTX 4000 Ada.

The individual Geekbench results also highlight the nature of the wins. In OpenCL, the RTX 4000 Ada’s 48.9% lead suggests it handles raw compute throughput far better, which aligns with its higher FP32 performance of 26.73 TFLOPS versus the Vega II Duo’s 14.09 TFLOPS. In Vulkan, the gap narrows to 24.7%, indicating that the Vega II Duo’s dual-GPU design may help in certain low-level API workloads, but it still cannot overcome the NVIDIA card’s architectural efficiency. The data does not support any interpretation where the Vega II Duo is competitive in these metrics.

The Verdict

From the benchmark data alone, the NVIDIA RTX 4000 Ada Generation is the superior product for general workstation compute. It wins both head-to-head tests by double-digit margins, has a higher average benchmark score, and achieves a higher percentile ranking. The RTX 4000 Ada is also an active production card with a modern architecture, while the Vega II Duo is end-of-life, which matters for long-term driver support and software compatibility. If you are choosing strictly on performance, the RTX 4000 Ada is the clear pick.

However, the Vega II Duo is not without its own merits, particularly if your workflow depends on the Apple MPX bus interface and macOS-specific features. The Vega II Duo’s launch MSRP was 4,399 USD, and it was designed specifically for Radeon Pro Mac systems, as indicated by its generation name “Radeon Pro Mac (Vega Series).” If you are locked into a Mac Pro environment that uses the Apple MPX form factor, the RTX 4000 Ada may not even be a physical option, as it uses a standard PCIe 4.0 x16 interface. For those users, the Vega II Duo’s 32 GB of HBM2 memory and 1.02 TB/s bandwidth could be more valuable than raw compute scores, especially if you are working with large datasets that fit in its VRAM. The data shows the NVIDIA card is faster, but the Vega II Duo is the only one of the two that fits into Apple’s proprietary expansion slot.

Where Each One Wins

The RTX 4000 Ada Generation wins in every benchmark where both cards were tested, so its advantages are straightforward. It leads by 48.9% in OpenCL, making it the better choice for OpenCL-based rendering, simulation, and scientific computing. It also leads by 24.7% in Vulkan, which covers modern game engines and Vulkan-based GPU compute. The RTX 4000 Ada’s higher FP32 throughput (26.73 TFLOPS) and higher texture rate (417.6 GTexel/s) versus the Vega II Duo’s 14.09 TFLOPS and 440.3 GTexel/s suggest it excels in tasks that depend on shader compute and modern API efficiency. Additionally, the RTX 4000 Ada has dedicated RT cores (48) and tensor cores (192), which the Vega II Duo lacks entirely, making the NVIDIA card the only option here for ray-traced workloads or AI inference using Tensor Core acceleration.

The Vega II Duo’s wins are not in benchmark scores but in specific hardware characteristics. It offers 32 GB of memory versus the RTX 4000 Ada’s 20 GB, and its memory bandwidth of 1.02 TB/s dwarfs the NVIDIA card’s 360.0 GB/s, thanks to a 4096-bit bus and HBM2. For memory-bound tasks like large-scale data visualization, video editing with high-resolution footage, or machine learning datasets that exceed 20 GB, the Vega II Duo provides a capacity and bandwidth advantage that the RTX 4000 Ada cannot match, despite its slower compute. The Vega II Duo also has more TMUs (256 vs. 192), giving it a slightly higher texture fill rate of 440.3 GTexel/s versus 417.6 GTexel/s, though this marginal lead is unlikely to offset the compute gap. In a dual-GPU configuration, the Vega II Duo’s design might also provide parallelism benefits in compatible applications, though the benchmark data does not show this translating into a win here.

Architecture Differences

The RTX 4000 Ada Generation is built on the AD104 chip using NVIDIA’s Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. It packs 35,800 million transistors into a 294 mm² die, yielding a transistor density of 121.8M per mm². The Vega II Duo uses the Vega 20 chip with AMD’s older GCN 5.1 architecture, on a 7 nm process, with 13,230 million transistors across a larger 331 mm² die, giving a lower density of 40.0M per mm². This architectural gap is fundamental: Ada Lovelace is designed for modern APIs and features like DirectX 12 Ultimate (12_2) and Vulkan 1.4, while GCN 5.1 supports DirectX 12 (12_1) and Vulkan 1.3.

The RTX 4000 Ada has 6,144 shading units, 192 TMUs, 64 ROPs, 48 RT cores, and 192 tensor cores, with a boost clock of 2175 MHz. The Vega II Duo, by contrast, has 4,096 shading units, 256 TMUs, 64 ROPs, and no RT or tensor cores, with a lower boost clock of 1720 MHz. The NVIDIA card’s FP32 performance is 26.73 TFLOPS, nearly double the Vega II Duo’s 14.09 TFLOPS, but the AMD card’s FP16 output is 28.18 TFLOPS (2:1 ratio) versus the RTX 4000 Ada’s 26.73 TFLOPS (1:1 ratio), meaning the Vega II Duo can exceed the NVIDIA card in FP16 workloads if the software supports it. The RTX 4000 Ada’s pixel rate is 139.2 GPixel/s versus 110.1 GPixel/s for the Vega II Duo, and its texture rate is 417.6 GTexel/s versus 440.3 GTexel/s, showing a mixed bag in rasterization throughput.

Specification Differences

The two cards differ in nearly every specification category. The RTX 4000 Ada has a base clock of 1500 MHz and boost of 2175 MHz, while the Vega II Duo runs at 1400 MHz base and 1720 MHz boost. Memory is a major divergence: the RTX 4000 Ada uses 20 GB of GDDR6 with a 160-bit bus and 360.0 GB/s bandwidth, while the Vega II Duo uses 32 GB of HBM2 with a 4096-bit bus and 1.02 TB/s bandwidth. The RTX 4000 Ada has a TDP of 130 W and requires a single 16-pin power connector with a suggested PSU of 300 W; the Vega II Duo draws 475 W with a suggested PSU of 850 W and has no listed power connectors, reflecting its Apple MPX integration.

Physical dimensions also differ sharply: the RTX 4000 Ada is single-slot, 245 mm long and 112 mm high, while the Vega II Duo is quad-slot with no listed dimensions. Display outputs are 4x DisplayPort 1.4a on the NVIDIA card versus 1x HDMI 2.0b and 4x Thunderbolt on the AMD card. The bus interface is PCIe 4.0 x16 for the RTX 4000 Ada and Apple MPX for the Vega II Duo. Release dates are 2023-08-08 for the NVIDIA card and 2019-06-02 for the AMD card, and the RTX 4000 Ada has a successor (Blackwell PRO W) while the Vega II Duo has none. The RTX 4000 Ada’s predecessor is Workstation Ampere, whereas the Vega II Duo has no listed predecessor.
