AMD Instinct MI300A vs NVIDIA RTX PRO 2000 Blackwell Comparison

Head-to-Head Benchmarks

The database contains a complete benchmark record for the NVIDIA RTX PRO 2000 Blackwell, while the AMD Instinct MI300A has no recorded benchmark scores. This makes a direct numerical comparison impossible; the analysis instead relies on the architectural data for the MI300A and the measured scores for the RTX PRO 2000.

The RTX PRO 2000 Blackwell achieves an average benchmark score of 25269, placing it in the 70th percentile of all GPUs in the database. Its strongest recorded result is in Geekbench Vulkan, where it scores 113865, followed by Geekbench OpenCL at 106087. The Passmark G3D score is 20049, while Passmark GPU Compute reaches 8396. The DirectX-specific Passmark tests are considerably lower: DirectX 11 scores 174, DirectX 10 scores 122, DirectX 12 scores 80, and DirectX 9 scores 241. The 2D workload score is 1303.

The MI300A has no benchmark entries, no average score, and no nearest rivals recorded. Its percentile versus all GPUs is listed as 50, but with a zero average benchmark score, this percentile should be interpreted as a placeholder rather than a measured result. The RTX PRO 2000, by contrast, has a full suite of ten benchmark results across DirectX, OpenCL, Vulkan, and compute workloads.

The nearest rivals for the RTX PRO 2000 provide context for its standing. The AMD Radeon RX 6700M averages 25633, which is 1.4 percent higher than the RTX PRO 2000. The AMD Radeon Pro W5700 averages 25726, also 1.8 percent higher. The NVIDIA GeForce RTX 3080 Ti Mobile averages 25740, again 1.8 percent higher. The NVIDIA RTX A5000 Mobile averages 24763, which is 2.0 percent lower than the RTX PRO 2000. The RTX PRO 2000 therefore sits slightly below a cluster of mobile and workstation GPUs but ahead of the RTX A5000 Mobile by a small margin.

Where Each One Wins

The RTX PRO 2000 Blackwell wins in every measurable category simply because it has recorded data. Its Vulkan score of 113865 and OpenCL score of 106087 indicate strong general compute and graphics API performance. The Passmark G3D score of 20049 confirms solid 3D rendering capability, while the Passmark G2D score of 1303 represents the 2D workload segment. The GPU compute score of 8396 reflects compute-oriented tasks outside the graphics pipeline.

The DirectX scores tell a different story. Passmark DirectX 9 at 241, DirectX 11 at 174, DirectX 10 at 122, and DirectX 12 at 80 show that the RTX PRO 2000 performs better under older DirectX versions than under the latest one. This pattern suggests the card handles legacy workloads more comfortably than modern DirectX 12 titles, at least based on the Passmark test suite.

The MI300A wins in raw architectural scale. It has 128 GB of HBM3 memory on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The RTX PRO 2000 has 16 GB of GDDR7 on a 128-bit bus, delivering 288.0 GB/s. The MI300A also has 14592 shading units, 912 texture mapping units, and a texture rate of 1,915.2 GTexel/s. Its FP32 throughput is 61.29 TFLOPS. The RTX PRO 2000 has 4352 shading units, 136 TMUs, 48 ROPs, and an FP32 rate of 17.03 TFLOPS. The MI300A is substantially larger in every compute-oriented specification.

The MI300A has no display outputs, while the RTX PRO 2000 has 4x mini-DisplayPort 2.1b. This makes the RTX PRO 2000 the only one of the two that can drive a monitor directly. The MI300A is an OAM module with no power connectors listed, while the RTX PRO 2000 is a dual-slot card with no power connectors listed as well.

The Verdict

The data supports a clear split. The AMD Instinct MI300A is designed for extreme compute capacity: 128 GB of HBM3, 5.32 TB/s of memory bandwidth, 61.29 TFLOPS of FP32, and 1,915.2 GTexel/s of texture throughput. It has no display outputs and no recorded benchmarks, so its role is clearly not client-side graphics or workstation visualization. The RTX PRO 2000 Blackwell, with its 70th percentile standing, 25269 average score, and full DirectX, Vulkan, and OpenCL API support, is the only one of the two that can be evaluated through measured performance.

Users who need a GPU with verified benchmark results, display outputs, and workstation graphics features should select the RTX PRO 2000 Blackwell. It delivers a measured average score of 25269, places 2.0 percent ahead of the RTX A5000 Mobile, and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its 16 GB of GDDR7 memory and 288.0 GB/s bandwidth are modest but recorded.

Users who need massive memory capacity and raw compute throughput on paper should select the AMD Instinct MI300A. Its 128 GB HBM3 pool, 8192-bit bus, and 61.29 TFLOPS FP32 are unmatched by the RTX PRO 2000 in specification terms. However, the MI300A has zero benchmark scores in the database, so its real-world standing cannot be confirmed from measured data. The RTX PRO 2000 is the only one with evidence.
