AMD Instinct MI350X vs NVIDIA RTX PRO 2000 Blackwell Comparison

Head-to-Head Benchmarks

The recorded database contains no shared benchmark results between the AMD Instinct MI350X and the NVIDIA RTX PRO 2000 Blackwell. The MI350X has an empty benchmark array, while the RTX PRO 2000 Blackwell has results across ten tests. Direct score comparison is therefore impossible from the available data.

The MI350X is placed in the 50th percentile of all GPUs in the database, with an average benchmark score of zero. This does not indicate a lack of capability, rather it reflects the absence of recorded test data for this part. The RTX PRO 2000 Blackwell sits in the 70th percentile, with an average benchmark score of 25,269.

For the RTX PRO 2000 Blackwell, the strongest recorded result is in Geekbench Vulkan at 113,865, with Geekbench OpenCL close behind at 106,087. The 3DMark Steel Nomad DX12 result is 2,374.5. Passmark G3D shows 20,049, while Passmark GPU Compute records 8,396. The legacy DirectX tests are much lower: DirectX 9 at 241, DirectX 11 at 174, DirectX 10 at 122, and DirectX 12 at 80. The G2D result is 1,303.

The nearest rivals for the RTX PRO 2000 Blackwell provide context for its average score. The NVIDIA RTX A5000 Mobile averages 24,763, meaning the RTX PRO 2000 Blackwell is 2% ahead. The AMD Radeon RX 6700M averages 25,633, which is 1.4% higher than the RTX PRO 2000 Blackwell. The AMD Radeon Pro W5700 averages 25,726, a 1.8% advantage, and the NVIDIA GeForce RTX 3080 Ti Mobile averages 25,740, also 1.8% higher. These deltas are small, placing the RTX PRO 2000 Blackwell in a tight competitive cluster.

Without MI350X benchmark data, no head-to-head wins can be assigned to either part. The winsA and winsB counters both stand at zero. The database records no scenario where the MI350X outperforms the RTX PRO 2000 Blackwell in a shared test, nor the reverse. This is a data limitation, not a performance verdict.

Architecture Differences

The two accelerators represent fundamentally different design philosophies. The AMD Instinct MI350X uses CDNA 4.0 architecture, built on a 3 nm process at TSMC. The NVIDIA RTX PRO 2000 Blackwell uses Blackwell 2.0 architecture, also fabricated by TSMC but on a 5 nm node. The process difference is significant: 3 nm versus 5 nm, which affects transistor density and power characteristics.

Transistor counts diverge sharply. The MI350X packs 185,000 million transistors on a die size of 2,380 mm², yielding a density of 77.7 million transistors per square millimeter. The RTX PRO 2000 Blackwell contains 21,900 million transistors on a 181 mm² die, with a density of 121.0 million per square millimeter. The MI350X has roughly 8.4 times the transistor count and a die over 13 times larger, but the NVIDIA chip achieves a higher transistor density per area.

The MI350X uses the MI350 256CU chip, reflecting a compute-oriented design with 16,384 shading units and 1,024 texture mapping units. It has no ROPs, no ray tracing cores, and no tensor cores listed in the database. The RTX PRO 2000 Blackwell uses the GB206 chip with 4,352 shading units, 136 TMUs, 48 ROPs, 34 ray tracing cores, and 136 tensor cores. The MI350X has nearly four times the shading units, but the NVIDIA part includes dedicated ray tracing and tensor hardware.

Memory architecture is where the designs diverge most clearly. The MI350X carries 288 GB of HBM3e on an 8,192-bit bus, delivering 8.19 TB/s of bandwidth. The RTX PRO 2000 Blackwell has 16 GB of GDDR7 on a 128-bit bus, with 288.0 GB/s of bandwidth. The MI350X provides 18 times the memory capacity and roughly 28 times the bandwidth. The NVIDIA part uses a conventional GDDR7 setup suited to workstation graphics; the AMD part is built for massive data movement typical of compute accelerators.

Clock behavior differs as well. The MI350X runs at a 1,000 MHz base and 2,200 MHz boost, with memory at 2,000 MHz (8 Gbps effective). The RTX PRO 2000 Blackwell has a 982 MHz base and 1,957 MHz boost, with memory at 1,125 MHz (18 Gbps effective). The AMD chip has higher base and boost clocks, but the NVIDIA memory runs at a faster effective data rate.

API support separates the two entirely. The MI350X lists DirectX, OpenGL, and Vulkan as N/A. The RTX PRO 2000 Blackwell supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI350X has no display outputs; the RTX PRO 2000 Blackwell has four mini-DisplayPort 2.1b outputs. These are not competing in the same segment.

Where Each One Wins

The RTX PRO 2000 Blackwell wins in any graphics-oriented workload. Its recorded benchmarks cover DirectX, OpenCL, Vulkan, and Passmark graphics tests, all of which return usable scores. The presence of ray tracing cores and tensor cores, combined with 48 ROPs and a 93.94 GPixel/s pixel rate, positions it for rendering, visualization, and AI inference at workstation scale. Its 70th percentile ranking and non-zero average score reflect a measurable presence in the database.

The MI350X wins in raw compute capacity. Its 72.09 TFLOPS FP32 and FP16 (1:1) output dwarfs the RTX PRO 2000 Blackwell's 17.03 TFLOPS in both formats. The texture rate of 2,252.8 GTexel/s is roughly 8.5 times the NVIDIA part's 266.2 GTexel/s. The 288 GB HBM3e pool with 8.19 TB/s bandwidth is in a different class entirely from 16 GB GDDR7. The MI350X is designed for large-scale compute, training, and inference workloads where memory capacity and bandwidth dominate.

The power envelope tells the same story. The MI350X has a 1,000 W TDP with a 1,400 W suggested PSU, while the RTX PRO 2000 Blackwell draws 70 W with a 250 W suggested PSU. The MI350X requires an OAM module form factor with no power connectors listed, reflecting a data-center installation. The RTX PRO 2000 Blackwell is a dual-slot card, 167 mm long, 69 mm tall, and 20 mm wide, with no power connectors and a 250 W PSU recommendation. The MI350X is 102 mm long and 165 mm wide, a different physical class.

Form factor and connectivity reinforce the split. The MI350X uses PCIe 5.0 x16. The RTX PRO 2000 Blackwell uses PCIe 5.0 x8. The MI350X has no display outputs. The RTX PRO 2000 Blackwell has four mini-DisplayPort 2.1b connectors. One is an accelerator for servers; the other is a workstation GPU for desktop use.
