AMD Instinct MI300X vs NVIDIA RTX PRO 2000 Blackwell Comparison

Head-to-Head Benchmarks

The database contains a single shared benchmark result for these two accelerators, and the gap is decisive. In Geekbench OpenCL, the AMD Instinct MI300X records a score of 317994, while the NVIDIA RTX PRO 2000 Blackwell scores 106087. The delta is 199.7%, placing the AMD part at nearly triple the performance of the NVIDIA workstation card in this compute-oriented workload.

Context from the nearest rival lists strengthens this reading. The MI300X sits at the 100th percentile of all GPUs in the database, with an average benchmark score of 317994. Its closest comparison points include the NVIDIA H200 NVL (334891, 5% higher), the NVIDIA B200 (345482, 8% higher), and the NVIDIA L40S (295763, 7.5% lower). The RTX PRO 2000 Blackwell, by contrast, sits at the 70th percentile with an average score of 25269. Its nearest rivals are substantially closer: the AMD Radeon RX 6700M (25633, 1.4% higher), the AMD Radeon Pro W5700 (25726, 1.8% higher), and the NVIDIA GeForce RTX 3080 Ti Mobile (25740, 1.8% higher).

The implication is clear: the MI300X is not merely ahead of the RTX PRO 2000 in raw compute, it is in a different performance class entirely. The RTX PRO 2000's nearest rivals are mobile and midrange workstation parts, while the MI300X's nearest rivals are top-tier data center accelerators. The 199.7% lead in OpenCL reflects the fundamental positioning gap between a 750 W OAM module designed for dense compute and a 70 W dual-slot workstation card.

The RTX PRO 2000 has other benchmark entries in the database, including 3DMark Steel Nomad (2374.5), Passmark G3D (20049), and Passmark GPU Compute (8396), but the MI300X has no corresponding entries for those tests. The only overlapping metric is Geekbench OpenCL, and the MI300X wins it outright. The recorded data shows no test where the RTX PRO 2000 outperforms the MI300X.

Architecture Differences

The two chips come from different architectural lineages. The MI300X uses the Aqua Vanjaram chip with CDNA 3.0 architecture, while the RTX PRO 2000 Blackwell uses the GB206 chip with Blackwell 2.0 architecture. Both are fabricated on a 5 nm process at TSMC, but the similarity ends there.

The MI300X packs 153,000 million transistors onto a 1017 mm² die, yielding a transistor density of 150.4 million per mm². The RTX PRO 2000 has 21,900 million transistors on a 181 mm² die, with a density of 121.0 million per mm². The MI300X die is roughly 5.6 times larger by area and holds 7 times more transistors. This scale difference is the primary driver of the performance gap.

Memory subsystems diverge sharply. The MI300X carries 192 GB of HBM3 across 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, with 288.0 GB/s of bandwidth. The MI300X offers 12 times the capacity and roughly 18.5 times the bandwidth. The effective memory clock differs as well: 5.2 Gbps for the MI300X versus 18 Gbps for the RTX PRO 2000, though the latter's narrow bus limits aggregate throughput.

Compute resources show a similar imbalance. The MI300X has 19,456 shading units and 1,216 texture mapping units, with no ROPs and no dedicated ray tracing or tensor core counts listed. The RTX PRO 2000 has 4,352 shading units, 136 TMUs, 48 ROPs, 34 ray tracing cores, and 136 tensor cores. The MI300X's FP32 throughput is 81.72 TFLOPS, while the RTX PRO 2000 delivers 17.03 TFLOPS, a 4.8x difference. Both list FP16 at the same rate as FP32 (1:1), but the MI300X's absolute FP16 figure remains 81.72 TFLOPS versus 17.03 TFLOPS for the RTX PRO 2000.

Pixel and texture rates reflect their different roles. The MI300X reports 0 MPixel/s and 2,553.6 GTexel/s. The RTX PRO 2000 reports 93.94 GPixel/s and 266.2 GTexel/s. The MI300X has no display outputs, while the RTX PRO 2000 offers 4x mini-DisplayPort 2.1b. The MI300X supports no DirectX, OpenGL, or Vulkan APIs; the RTX PRO 2000 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data indicates these are not competing products. The MI300X dominates the only shared benchmark, Geekbench OpenCL, with a 199.7% lead. Its nearest rivals are the NVIDIA H200 NVL, B200, and L40S, all data center accelerators. The RTX PRO 2000's nearest rivals are the Radeon RX 6700M, Radeon Pro W5700, and RTX 3080 Ti Mobile, all mobile or midrange parts. The percentile ranking confirms the gap: 100th percentile for the MI300X versus 70th for the RTX PRO 2000.

The RTX PRO 2000 is a workstation card with display outputs, ray tracing cores, tensor cores, and full API support. The MI300X has no display outputs, no API support, and no listed ray tracing or tensor cores. It is an OAM module designed for server installation. The MI300X requires a 1150 W suggested PSU and consumes 750 W; the RTX PRO 2000 requires a 250 W suggested PSU and consumes 70 W.

Which one to pick depends entirely on workload. For compute-heavy tasks that fit within the database's OpenCL measurement, the MI300X is the clear choice. For graphics, display output, or API-dependent workloads, the RTX PRO 2000 has capabilities the MI300X simply does not list.

Where Each One Wins

AMD Instinct MI300X wins on raw compute. The Geekbench OpenCL score of 317994 versus 106087 is the only direct comparison, and it is a 199.7% victory. The MI300X also wins on memory capacity (192 GB versus 16 GB), memory bandwidth (5.32 TB/s versus 288.0 GB/s), transistor count (153,000 million versus 21,900 million), die size (1017 mm² versus 181 mm²), shading units (19,456 versus 4,352), texture rate (2,553.6 GTexel/s versus 266.2 GTexel/s), and FP32 throughput (81.72 TFLOPS versus 17.03 TFLOPS). Its nearest rivals are the NVIDIA B200, H200 NVL, and L40S, placing it firmly in the data center class.

NVIDIA RTX PRO 2000 Blackwell wins on features and efficiency. It has 48 ROPs where the MI300X has 0, giving it a pixel rate of 93.94 GPixel/s versus 0 MPixel/s. It offers 34 ray tracing cores and 136 tensor cores, neither of which the MI300X lists. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI300X supports none. It has 4x mini-DisplayPort 2.1b outputs, while the MI300X has none. Its TDP is 70 W versus 750 W, and its suggested PSU is 250 W versus 1150 W. Its nearest rivals are mobile and midrange workstation parts, indicating it competes in a lower performance tier but with a broader feature set.

The MI300X has 1 benchmark win in the head-to-head data; the RTX PRO 2000 has 0. The MI300X also holds a higher percentile ranking (100 versus 70) and a higher average benchmark score (317994 versus 25269). The RTX PRO 2000 has additional benchmark entries in 3DMark and Passmark tests, but the MI300X has no corresponding data for those tests, so no comparison is possible there.
