Q: Which card has better API support?

A: The RTX 5000 Ada supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon Pro Vega 64X supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The NVIDIA card has a higher DirectX feature level and a newer Vulkan version.

The Verdict

The data is unambiguous in raw performance: the RTX 5000 Ada Generation is the far faster card. It leads by 123.4% in the only head-to-head OpenCL benchmark, and its average score of 184,664 crushes the Radeon Pro Vega 64X’s 80,959. For anyone needing maximum compute throughput, large memory capacity, or modern feature support, the RTX 5000 Ada is the clear choice.

However, the Radeon Pro Vega 64X is not without a role. It is an integrated part of a portable device, not a standalone add-in card. It has no power connectors, no slot width requirement, and its display output is dependent on the host system. This makes it suitable only for users who already own a device built around it, such as a specific Apple Mac workstation. If you are in that ecosystem and cannot replace the device, the Vega 64X remains a functional option, but it is end-of-life and cannot compete on performance.

The verdict is simple: for new builds, upgrades, or any workload where you can choose the GPU, the RTX 5000 Ada wins on every measurable performance metric. The Radeon Pro Vega 64X is only relevant if your hardware platform is fixed and you have no other options.

Head-to-Head Benchmarks

The only direct comparison in the database is the Geekbench OpenCL test. The RTX 5000 Ada scores 175,286, and the Radeon Pro Vega 64X scores 78,467. That is a delta of 123.4%, meaning the NVIDIA card is more than twice as fast. The RTX 5000 Ada also has a Geekbench Vulkan score of 194,041, which is even higher than its OpenCL result, although the AMD card has no corresponding Vulkan score in the database for a direct comparison.

The Radeon Pro Vega 64X does have a Geekbench Metal score of 83,450, which is a test the RTX 5000 Ada does not have recorded. This indicates the AMD card has some strength in Metal-based workloads, which is relevant for macOS environments. However, its OpenCL score of 78,467 is far below the RTX 5000 Ada’s OpenCL result.

In terms of average benchmark score, the RTX 5000 Ada’s 184,664 is 128% higher than the Radeon Pro Vega 64X’s 80,959. The RTX 5000 Ada’s closest rivals are the NVIDIA A100 SXM4 80 GB (within 0.5%), the A100 SXM4 40 GB (1.3% higher), the RTX PRO 5000 Blackwell (1.4% ahead), and the GeForce RTX 4090 D (3.7% ahead). This shows the RTX 5000 Ada is in the same performance class as top-tier data center and high-end consumer cards. The Radeon Pro Vega 64X’s rivals are the Radeon PRO W6600 (1.3% ahead), the GeForce RTX 5090 (1.4% behind), and the Tesla P100 variants (1.7% and 2.0% behind). This places it in a much lower performance tier, around mid-range professional cards from a few generations back.

Specification Differences

The two cards differ across nearly every specification. The RTX 5000 Ada uses the AD102 chip on a 5 nm process from TSMC, with 76,300 million transistors on a 609 mm² die. That gives a transistor density of 125.3 million per mm². The Radeon Pro Vega 64X uses the Vega 10 chip on a 14 nm process from GlobalFoundries, with 12,500 million transistors on a 495 mm² die, for a density of 25.3 million per mm². The RTX 5000 Ada packs more than six times the transistor count into a slightly larger die.

Memory is also different: the RTX 5000 Ada has 32 GB of GDDR6 on a 256-bit bus, with 576.0 GB/s bandwidth. The Radeon Pro Vega 64X has 16 GB of HBM2 on a 2048-bit bus, with 512.0 GB/s bandwidth. The wider bus does not help the AMD card, as its lower memory clock gives less bandwidth.

The RTX 5000 Ada has 12,800 shading units, 400 TMUs, and 176 ROPs. It also features 100 ray tracing cores and 400 tensor cores. The Radeon Pro Vega 64X has 4,096 shaders, 256 TMUs, and 64 ROPs, with no ray tracing or tensor cores listed. The pixel rates are 448.8 GPixel/s for the NVIDIA card versus 93.95 GPixel/s for the AMD card. Texture rates are 1,020.0 GTexel/s versus 375.8 GTexel/s.

Compute throughput shows a similar gap: the RTX 5000 Ada delivers 65.28 TFLOPS FP32 and 65.28 TFLOPS FP16 (1:1 ratio). The AMD card offers 12.03 TFLOPS FP32 and 24.05 TFLOPS FP16 (2:1 ratio), meaning its FP16 is only about 37% of the NVIDIA FP16 performance.

The RTX 5000 Ada uses PCIe 4.0 x16, while the Radeon Pro Vega 64X uses PCIe 3.0 x16. The NVIDIA card has 4x DisplayPort 1.4a outputs; the AMD card has none, depending on the portable device. The RTX 5000 Ada has dimensions of 267 mm in length and 112 mm in height, while the AMD card has no recorded dimensions.

Architecture Differences

The two GPUs come from different architectural generations. The RTX 5000 Ada is based on Ada Lovelace, NVIDIA’s workstation architecture. It uses a 5 nm process, which is much denser and more power-efficient than the AMD card’s 14 nm node. The RTX 5000 Ada includes dedicated ray tracing cores (100) and tensor cores (400), which support hardware-accelerated ray tracing and AI workloads. The Radeon Pro Vega 64X is based on GCN 5.0, a much older architecture with no ray tracing or tensor cores. Its FP16 performance is double its FP32 (2:1), while the RTX 5000 Ada has a 1:1 ratio, meaning it does not sacrifice FP16 throughput.

The RTX 5000 Ada supports DirectX 12 Ultimate (feature level 12_2) and Vulkan 1.4, while the Radeon Pro Vega 64X only supports DirectX 12 (feature level 12_1) and Vulkan 1.3. This means the NVIDIA card is better equipped for modern graphics APIs and the features they enable.

The Radeon Pro Vega 64X is designed as an IGP (integrated graphics processor), not a discrete card, which explains its lack of power connectors and its portable device dependent display outputs. This is a fundamental difference in form factor: one is a standard dual-slot card for a PCIe slot, the other is an integrated chip for a specific Mac system.

Where Each One Wins

The RTX 5000 Ada Generation wins in every measureable performance category. It is 123.4% ahead in the Geekbench OpenCL test, has a higher average benchmark score, and holds better memory capacity (32 GB vs. 16 GB). It also has higher bandwidth (576.0 GB/s vs. 512.0 GB/s), higher FP32 compute (65.28 vs. 12.03 TFLOPS), and higher pixel/texture rates. The RTX 5000 Ada has ray tracing and tensor cores, which the AMD cards lacks, making it far more capable for modern 3D rendering, AI inference, and graphics workloads. It is also on a newer process node, supports PCIe 4.0, and has a modern API feature set with DirectX 12 Ultimate.

The Radeon Pro Vega 64X has a few narrow wins. It is an integrated solution that requires no power connectors and no additional space, making it suitable for portable devices. It has a wider 2048-bit memory bus, though this does not result in higher bandwidth. It has a Geekbench Metal score of 83,450, which is a test the RTX 5000 Ada does not have recorded, so in Metal-specific workloads (common in macOS), it has a measurable result. It also has a lower TDP (250 W) and no suggested PSU requirement, which is an advantage for power-restricted systems.

For practical use, the RTX 5000 Ada is the choice for any workstation that demands compute performance, large memory pools, or modern features. The Radeon Pro Vega 64X is only a realistic option for someone who is stuck with a Mac Pro system from 2019 or earlier and cannot replace the GPU. In that specific case, it is an adequate 92nd percentile card, but it is outclassed by every recent high-end GPU, including those in its own rivalry list, such as the Radeon PRO W6600 and the GeForce RTX 5090. The data is clear: the RTX 5000 Ada is the superior product in every direct performance comparison.
