AMD Instinct MI350X vs NVIDIA RTX 5880 Ada Generation Comparison

Head-to-Head Benchmarks

The database contains no shared benchmark results for the AMD Instinct MI350X and the NVIDIA RTX 5880 Ada Generation. The MI350X has no recorded benchmark scores, an average benchmark score of zero, and sits at the 50th percentile among all GPUs. The RTX 5880 Ada Generation, by contrast, has eight recorded benchmark entries and an average benchmark score of 45,972, placing it at the 85th percentile.

Since no head-to-head test results exist, the comparison must rely on the separately recorded data. The RTX 5880 Ada Generation delivers a Geekbench OpenCL score of 326,898. Its Passmark results include a G3D score of 25,096, a GPU compute score of 14,208, and DirectX scores of 167 (DirectX 10), 228 (DirectX 11), 70 (DirectX 12), and 335 (DirectX 9). The G2D score is 777. These are the only quantitative performance measurements available in the database for either product.

The MI350X's 50th percentile ranking with zero benchmark entries means it cannot be positioned against the RTX 5880 Ada Generation's 85th percentile ranking in any direct numerical fashion. The RTX 5880 Ada Generation's nearest rivals in the database are the NVIDIA RTX A2000 (average score 46,043, delta -0.2%), the Intel Arc A730M (average score 45,592, delta 0.8%), the AMD Radeon Pro 5500 XT (average score 45,384, delta 1.3%), and the AMD Radeon RX 5600M (average score 46,601, delta -1.4%). These deltas indicate the RTX 5880 Ada Generation scores essentially within 1.4% of all four nearest rivals, showing a tightly clustered performance band around its 45,972 average.

The MI350X's theoretical FP32 throughput is 72.09 TFLOPS, while the RTX 5880 Ada Generation delivers 69.27 TFLOPS. This 2.82 TFLOPS gap favors the MI350X in raw floating-point capability. Both products list FP16 at a 1:1 ratio with FP32, meaning the MI350X also reaches 72.09 TFLOPS FP16 and the RTX 5880 Ada Generation reaches 69.27 TFLOPS FP16. However, theoretical throughput does not translate directly into recorded benchmark scores, and the database shows no evidence of actual MI350X workload results.

Physical dimensions show the MI350X at 102 mm length and 165 mm width, while the RTX 5880 Ada Generation is 267 mm long and 112 mm tall. The MI350X is an OAM module; the RTX 5880 Ada Generation is dual-slot. Power requirements are 1000 W TDP with a 1400 W suggested PSU for the MI350X, versus 285 W TDP and a 600 W suggested PSU for the RTX 5880 Ada Generation.

Architecture Differences

The MI350X is built on CDNA 4.0 architecture, part of the Instinct (MIx) generation, using the MI350 256CU chip. The RTX 5880 Ada Generation uses Ada Lovelace architecture with the AD102 chip, belonging to the Workstation Ada (x000A) generation and listed under the GeForce 50-series. The MI350X's predecessor is Radeon Instinct; the RTX 5880 Ada Generation's predecessor is Workstation Ampere, and its successor is Blackwell PRO W.

The MI350X has no display outputs and no graphics API support in the database (DirectX, OpenGL, and Vulkan all listed as N/A). The RTX 5880 Ada Generation provides 4x DisplayPort 1.4a outputs and full API support including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This indicates the MI350X is oriented toward compute-only workloads without a rendering path, while the RTX 5880 Ada Generation carries workstation graphics functionality.

Release timing differs: the MI350X was released on 2025-06-11, while the RTX 5880 Ada Generation was released on 2024-01-04. The RTX 5880 Ada Generation has an active production status; the MI350X has no production status recorded. The MI350X's memory type is HBM3e; the RTX 5880 Ada Generation uses GDDR6. The MI350X has no power connectors because it is an OAM module; the RTX 5880 Ada Generation uses a single 16-pin connector.

The MI350X's 185 billion transistors on a 2380 mm² die represent the larger physical implementation. The RTX 5880 Ada Generation's 76.3 billion transistors on 609 mm² show a denser arrangement. The 3 nm process gives the MI350X a node advantage, though the RTX 5880 Ada Generation's 5 nm process still achieves higher transistor density. Neither product lists a codename, and neither has a launch MSRP in the database.

The Verdict

The recorded data supports different selections depending on workload priorities. For compute tasks that require massive memory capacity and bandwidth, the MI350X is the clear choice: 288 GB versus 48 GB, 8.19 TB/s versus 864.0 GB/s, and an 8192-bit bus against a 384-bit bus. Its FP32 throughput of 72.09 TFLOPS also exceeds the RTX 5880 Ada Generation's 69.27 TFLOPS. The MI350X's 1,024 TMUs and 2,252.8 GTexel/s texture rate further indicate it is built for heavy data movement and compute density.

For workstation graphics, rendering, and any application that relies on recorded benchmark performance, the RTX 5880 Ada Generation is the only option with data. Its 326,898 Geekbench OpenCL score and 25,096 Passmark G3D score demonstrate functional performance. Its 176 ROPs, 110 RT cores, and 440 tensor cores provide hardware features the MI350X lacks entirely. The RTX 5880 Ada Generation also supports display outputs and the full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 API stack, making it usable as a general workstation GPU.

The power envelope favors the RTX 5880 Ada Generation decisively: 285 W TDP with a 600 W suggested PSU, versus 1000 W TDP and a 1400 W suggested PSU for the MI350X. Physical form factors also differ: the RTX 5880 Ada Generation installs as a dual-slot PCIe 4.0 card, while the MI350X is an OAM module with no display connectors. The RTX 5880 Ada Generation's PCIe 4.0 x16 interface contrasts with the MI350X's PCIe 5.0 x16.

The database shows no benchmark results for the MI350X, so any selection of that product must rely on its theoretical specifications rather than measured outcomes. The RTX 5880 Ada Generation has verified scores across eight tests and sits at the 85th percentile, with its nearest rivals within 1.4% of its average score. The MI350X's 50th percentile and zero recorded scores leave its real-world performance unquantified in this database. Users needing verified performance data should consider the RTX 5880 Ada Generation; users requiring extreme memory capacity and raw compute specifications should examine the MI350X's theoretical capabilities.
