AMD Instinct MI350P vs NVIDIA RTX PRO 6000 Blackwell Server Comparison

AMD Instinct MI350P and NVIDIA RTX PRO 6000 Blackwell Server occupy different corners of the accelerator market, yet both target serious compute workloads. The MI350P uses CDNA 4.0 with a 3 nm TSMC process, while the RTX PRO 6000 Blackwell Server uses Blackwell 2.0 on a 5 nm TSMC node. The data shows two designs with opposite priorities: the AMD part maximizes memory capacity and bandwidth, the NVIDIA part maximizes raw compute throughput and feature support.

Head-to-Head Benchmarks

The only recorded benchmark for the RTX PRO 6000 Blackwell Server is 3DMark Steel Nomad DX12, where it scores 5996. The MI350P has no benchmark entries in the database, so direct numeric comparison is limited to this single test. The RTX PRO 6000 Blackwell Server sits at the 34th percentile among all GPUs, with an average benchmark score of 5996. Its nearest rivals in the database are the NVIDIA GeForce GTX 770M at 6000 (0.1% faster), the AMD Radeon RX 6400 at 6001 (0.1% faster), the AMD FirePro W4100 at 5987 (0.2% slower), and the NVIDIA Quadro K4000M at 5986 (0.2% slower). This places the RTX PRO 6000 Blackwell Server in a narrow band around 6000 points, essentially tied with those four older or lower-tier cards in this specific workload.

The MI350P has zero benchmark scores, so its percentile is 50 by default, but that figure carries no measured weight. What the data does show is the FP32 compute difference: the RTX PRO 6000 Blackwell Server delivers 126.0 TFLOPS, versus 36.04 TFLOPS for the MI350P. That is a 3.5x advantage for the NVIDIA card in single-precision floating-point work. Texture rate follows the same pattern: 1,968.0 GTexel/s for the RTX PRO 6000 Blackwell Server versus 1,126.4 GTexel/s for the MI350P, a 75% lead. Pixel rate is even more lopsided: the NVIDIA card produces 502.5 GPixel/s, while the MI350P shows 0 MPixel/s, indicating no raster output pipeline is present on the AMD accelerator.

Memory bandwidth tells the opposite story. The MI350P delivers 8.19 TB/s over an 8192-bit bus, while the RTX PRO 6000 Blackwell Server provides 1.79 TB/s over a 512-bit bus. The AMD part has 4.6x the bandwidth. Capacity also favors AMD: 144 GB of HBM3e versus 96 GB of GDDR7, a 50% larger pool. Clock speeds differ as well, with the NVIDIA card boosting to 2617 MHz versus 2200 MHz for the AMD part, and base clocks of 1590 MHz versus 1000 MHz.

The Verdict

From the recorded data, the RTX PRO 6000 Blackwell Server is the clear choice for compute-bound workloads that rely on FP32 throughput, graphics pipelines, or API compatibility. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI350P reports N/A for all three APIs. The NVIDIA card also has 192 ROPs, 188 RT cores, and 752 tensor cores, none of which exist on the MI350P specification sheet. For rasterization, ray tracing, or any graphics-oriented task, the RTX PRO 6000 Blackwell Server is the only functional option between the two.

The MI350P wins decisively on memory characteristics. With 144 GB of HBM3e and 8.19 TB/s bandwidth, it holds a 48 GB capacity advantage and a 6.4 TB/s bandwidth advantage over the NVIDIA card. Workloads that are memory-bound, such as large model inference or data-intensive scientific computing, will favor the AMD part despite its lower FP32 throughput. The MI350P also has a higher transistor density at 61.3M per mm² versus 122.9M per mm² for the NVIDIA chip, though the NVIDIA die packs more total transistors: 92,200 million versus 73,000 million.

Neither card has a launch MSRP in the database. The RTX PRO 6000 Blackwell Server is marked as Active in production, while the MI350P has no production status recorded. Release timing differs: the NVIDIA card launched on 2025-03-17, the AMD card on 2026-05-06, roughly 14 months later.

Architecture Differences

The MI350P uses CDNA 4.0, AMD's compute-focused architecture, built on a 3 nm TSMC process. The chip is labeled MI350 128CU, with a die size of 1190 mm² and 73,000 million transistors. The RTX PRO 6000 Blackwell Server uses Blackwell 2.0 on a 5 nm TSMC node, with the GB202 chip, a 750 mm² die, and 92,200 million transistors. The NVIDIA die is 37% smaller in area but holds 26% more transistors, yielding a much higher density.

Shader core counts differ substantially: the MI350P has 8192 shading units, while the RTX PRO 6000 Blackwell Server has 24064, nearly 3x more. TMUs are 512 on the AMD part versus 752 on the NVIDIA part. The NVIDIA card includes 192 ROPs, 188 RT cores, and 752 tensor cores; the MI350P lists zero ROPs and no RT or tensor core counts. This reflects a fundamental design split: the MI350P is a pure compute accelerator with no display outputs, while the RTX PRO 6000 Blackwell Server has 4x DisplayPort 2.1b outputs.

Memory architecture is another major divergence. The MI350P uses HBM3e with an 8192-bit bus, running at 2000 MHz (8 Gbps effective), producing 8.19 TB/s. The RTX PRO 6000 Blackwell Server uses GDDR7 with a 512-bit bus, running at 1750 MHz (28 Gbps effective), producing 1.79 TB/s. The AMD part has 144 GB capacity; the NVIDIA part has 96 GB.

Power and physical specifications are identical in several respects. Both cards have a 600 W TDP, use a single 16-pin power connector, require a 1000 W suggested PSU, are dual-slot, and measure 267 mm by 111 mm by 40 mm. Both use PCIe 5.0 x16 interfaces.

Where Each One Wins

The RTX PRO 6000 Blackwell Server wins in any scenario that requires graphics processing. Its 192 ROPs produce 502.5 GPixel/s, and its 188 RT cores enable hardware ray tracing, which the MI350P completely lacks. The NVIDIA card also has 752 tensor cores, useful for AI-accelerated workloads that rely on Tensor Core operations, plus full API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The 24064 shading units and 752 TMUs give it a 1,968.0 GTexel/s texture rate, 75% higher than the MI350P. Its 126.0 TFLOPS FP32 output makes it the stronger choice for general-purpose compute that uses standard floating-point math.

The MI350P wins in memory-bound applications. Its 144 GB HBM3e pool is 50% larger than the NVIDIA card's 96 GB GDDR7, and its 8.19 TB/s bandwidth is 4.6x higher. For workloads that stream large datasets or hold massive models in memory, the AMD part avoids the capacity and bandwidth bottlenecks that would constrain the NVIDIA card. The 8192-bit bus width is unmatched by the 512-bit interface on the RTX PRO 6000 Blackwell Server. The MI350P also uses a smaller process node at 3 nm versus 5 nm, which contributes to higher transistor density per area, though the NVIDIA die has more total transistors.

The RTX PRO 6000 Blackwell Server has a higher boost clock at 2617 MHz versus 2200 MHz, and a higher base clock at 1590 MHz versus 1000 MHz. It also has a smaller die at 750 mm² versus 1190 mm², which may affect manufacturing yields and packaging considerations. The NVIDIA card launched earlier (2025-03-17) and has a successor listed as Server Rubin, while the MI350P has no successor recorded and its predecessor is Radeon Instinct.

For a server deployment where the task is graphics-adjacent, such as virtualized workstations or rendering, the RTX PRO 6000 Blackwell Server is the only viable option given the MI350P's lack of display outputs and graphics APIs. For pure compute with massive memory requirements, the MI350P's 144 GB and 8.19 TB/s provide a clear advantage that the NVIDIA card cannot match. The single benchmark in the database shows the NVIDIA card scoring 5996 in 3DMark Steel Nomad DX12, with rival scores within 0.2%, but that test is graphics-oriented and does not exercise the MI350P at all since no benchmark data exists for it. The choice depends entirely on whether the workload demands graphics features or memory bandwidth. Both cards consume 600 W, use the same power connector and PSU recommendation, and share identical physical dimensions, so system integration is comparable. The data does not include any pricing, so cost comparisons are not possible from these records.
