AMD Instinct MI325X vs NVIDIA RTX PRO 2000 Blackwell Comparison

Head-to-Head Benchmarks

The database contains no shared benchmark runs for the AMD Instinct MI325X and the NVIDIA RTX PRO 2000 Blackwell, so a direct score-for-score comparison is impossible. What the recorded data does show is a pair of accelerators built for entirely different workloads. The RTX PRO 2000 Blackwell has a full set of measured results across 3DMark, Geekbench, and Passmark suites. Its average benchmark score is 25,269, placing it in the 70th percentile of all GPUs in the database. The Instinct MI325X has no benchmark entries and sits at the 50th percentile with an average score of zero, which simply reflects the absence of consumer-oriented test data, not a performance verdict.

The RTX PRO 2000 Blackwell's nearest rivals in the database show how tightly it clusters with mobile and workstation parts. It trails the AMD Radeon RX 6700M by 1.4%, the AMD Radeon Pro W5700 by 1.8%, and the NVIDIA GeForce RTX 3080 Ti Mobile by 1.8%. Against the NVIDIA RTX A5000 Mobile, it leads by 2%. These deltas are small, all within a few percentage points, indicating that the RTX PRO 2000 Blackwell sits in a well-populated performance band rather than at an extreme. Its strongest single result is the Geekbench Vulkan score of 113,865, with OpenCL close behind at 106,087. Passmark G3D delivers 20,049, and Passmark GPU Compute reaches 8,396. The 3DMark Steel Nomad DX12 result of 2,374.5 is a modern DirectX 12 workload, while the older Passmark DX9 score of 241 shows legacy API performance.

The Instinct MI325X presents no comparable figures. Its FP32 rate of 81.72 TFLOPS and FP16 rate of 81.72 TFLOPS (1:1) are raw compute specifications, not application scores. The RTX PRO 2000 Blackwell delivers 17.03 TFLOPS in both FP32 and FP16. Those numbers indicate a roughly 4.8x gap in peak floating-point throughput, but they come from theoretical specifications, not benchmark runs. Similarly, texture rate favors the AMD part at 2,553.6 GTexel/s versus 266.2 GTexel/s for the NVIDIA card. The pixel rate comparison is one-sided: the Instinct MI325X lists 0 MPixel/s, meaning it has no ROP output for traditional rasterization, while the RTX PRO 2000 Blackwell delivers 93.94 GPixel/s.

Architecture Differences

The two chips diverge sharply in design philosophy. The AMD Instinct MI325X uses the Aqua Vanjaram die built on CDNA 3.0 architecture, manufactured on a 5 nm process at TSMC. It packs 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4M per mm². The NVIDIA RTX PRO 2000 Blackwell uses the GB206 chip with Blackwell 2.0 architecture, also on TSMC 5 nm, but with 21,900 million transistors on a 181 mm² die, for a density of 121.0M per mm². The AMD die is more than five times larger by area and holds nearly seven times the transistor count.

Memory systems are fundamentally different. The Instinct MI325X carries 256 GB of HBM3e across an 8192-bit bus, delivering 6.14 TB/s of bandwidth. The RTX PRO 2000 Blackwell uses 16 GB of GDDR7 on a 128-bit bus, with 288.0 GB/s of bandwidth. The AMD part offers 16 times the capacity and over 21 times the bandwidth. Clock behavior also differs: the AMD chip runs at a 1000 MHz base and 2100 MHz boost, while the NVIDIA chip runs at 982 MHz base and 1957 MHz boost. Memory clocks are listed as 1500 MHz with 6 Gbps effective for the AMD card and 1125 MHz with 18 Gbps effective for the NVIDIA card.

Compute resources tell the scale story. The Instinct MI325X has 19,456 shading units and 1,216 texture mapping units, with zero ROPs. The RTX PRO 2000 Blackwell has 4,352 shading units, 136 TMUs, and 48 ROPs. The NVIDIA part also includes 34 ray tracing cores and 136 tensor cores; the AMD card lists no RT or tensor core counts. The API support confirms the split: the Instinct MI325X reports N/A for DirectX, OpenGL, and Vulkan, while the RTX PRO 2000 Blackwell supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Power and physical design reinforce the different use cases. The Instinct MI325X has a 1000 W TDP, ships as an OAM module, and requires a 1400 W suggested PSU. The RTX PRO 2000 Blackwell runs at 70 W TDP, is a dual-slot card, and needs only a 250 W suggested PSU. Neither card uses external power connectors. The NVIDIA card has display outputs, specifically 4x mini-DisplayPort 2.1b, while the AMD card has no outputs. Dimensions also differ: the RTX PRO 2000 Blackwell measures 167 mm by 69 mm by 20 mm, while the Instinct MI325X lists no physical dimensions.

The Verdict

The database positions these two products in separate categories. The AMD Instinct MI325X is a compute accelerator with no display output, no graphics API support, and a 1000 W power envelope. Its defining characteristics are the 256 GB HBM3e memory pool, the 6.14 TB/s bandwidth, and the 81.72 TFLOPS FP32 rate. The 50th percentile standing and zero benchmark scores mean the database holds no application-level evidence of its performance, only its specifications.

The NVIDIA RTX PRO 2000 Blackwell is a workstation GPU with measured results. It supports DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4, has ray tracing and tensor cores, and outputs to four mini-DisplayPort 2.1b connectors. Its 70th percentile rank and average score of 25,269 come from real benchmark runs, and its nearest rivals are all within roughly 2% of its score. The 70 W TDP and dual-slot form factor make it a conventional card for graphics workstations.

The selection depends on the workload. A system needing massive memory capacity and raw compute throughput for server-side acceleration aligns with the Instinct MI325X. A system needing graphics rendering, API compatibility, display outputs, and a modest power draw aligns with the RTX PRO 2000 Blackwell. The data does not suggest one is superior; it shows two specialized tools with almost no functional overlap.
