AMD Instinct MI325X vs NVIDIA RTX 5000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the AMD Instinct MI325X and the NVIDIA RTX 5000 Mobile Ada Generation. The MI325X has no benchmark entries in the database, while the RTX 5000 Mobile Ada Generation has a single recorded 3DMark Steel Nomad DX12 score of 3596. This absence of overlapping test data means the comparison relies on architectural specifications and one available score rather than direct side-by-side measurements.

The RTX 5000 Mobile Ada Generation achieves an average benchmark score of 3596, placing it at the 21st percentile among all GPUs in the database. Its nearest rivals in the recorded data are the NVIDIA GeForce GT 545, which scores 3594 (a 0.1% delta), the NVIDIA GeForce GT 735M at 3616 (a -0.6% delta), the NVIDIA GeForce GTX 1050 at 3629 (a -0.9% delta), and the AMD Radeon HD 6770 at 3649 (a -1.5% delta). The RTX 5000 Mobile Ada Generation sits essentially even with the GT 545, only 0.1% ahead, and trails the GT 735M by 0.6%, the GTX 1050 by 0.9%, and the HD 6770 by 1.5%. These deltas are small, indicating that the recorded 3DMark Steel Nomad DX12 result places the mobile NVIDIA part within a narrow performance band relative to those older desktop and mobile GPUs.

The AMD Instinct MI325X has no benchmark scores, no average score, and no nearest rivals in the database. Its percentile rank is listed at 50, which reflects its position in the broader database hierarchy, but without benchmark entries, the percentile cannot be tied to measured performance. The MI325X, therefore, has no quantitative basis in the recorded data for a head-to-head comparison with the RTX 5000 Mobile Ada Generation in any benchmark suite. The data indicates that the NVIDIA part is the only one of the two with a measured score, and that score is low relative to the broader GPU population at the 21st percentile.

Where Each One Wins

Based on the recorded data, the NVIDIA RTX 5000 Mobile Ada Generation wins in the only measured benchmark category: it has a 3DMark Steel Nomad DX12 score of 3596, while the AMD Instinct MI325X has no recorded benchmark results. The NVIDIA part also supports a full API stack, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, which enables modern graphics workloads. Its display outputs are listed as "Portable Device Dependent," meaning it is designed for mobile systems where display connectivity is determined by the host device. The RTX 5000 Mobile Ada Generation includes 76 ray tracing cores and 304 tensor cores, making it equipped for ray-traced rendering and AI-accelerated tasks, though no specific benchmark data validates performance in those areas.

The AMD Instinct MI325X wins in raw compute capacity according to the specification data. Its FP32 throughput is 81.72 TFLOPS, which is 98.6% higher than the RTX 5000 Mobile Ada Generation's 41.15 TFLOPS. Its FP16 throughput is also 81.72 TFLOPS with a 1:1 ratio, matching the FP32 figure, while the NVIDIA part delivers 41.15 TFLOPS FP16 with a 1:1 ratio. The MI325X has 19,456 shading units versus 9,728 for the NVIDIA part, exactly double. Its texture rate is 2,553.6 GTexel/s compared to 643.0 GTexel/s, a difference of roughly 4x. The MI325X memory subsystem is substantially larger: 256 GB of HBM3e on an 8192-bit bus with 6.14 TB/s bandwidth, versus 16 GB of GDDR6 on a 256-bit bus with 576.0 GB/s bandwidth. The MI325X also leads in transistor count with 153,000 million transistors on a 1017 mm² die, compared to 45,900 million on 379 mm² for NVIDIA.

The MI325X has a pixel rate of 0 MPixel/s and 0 ROPs, which indicates the data records no rasterization output capability, consistent with a compute-focused accelerator. The NVIDIA part has a pixel rate of 236.9 GPixel/s and 112 ROPs, which gives it a clear advantage in rasterized graphics output. The MI325X has no display outputs, while the RTX 5000 Mobile Ada Generation supports portable device dependent outputs.

The Verdict

The data clearly separates these two products by purpose. The AMD Instinct MI325X is a high-power compute accelerator: 1000 W TDP, OAM Module form factor, no display outputs, no graphics API support, and a memory configuration of 256 GB HBM3e at 6.14 TB/s. Its FP32 performance of 81.72 TFLOPS is exactly twice the NVIDIA part, and its texture rate of 2,553.6 GTexel/s is roughly 4x higher. The MI325X generation is "Instinct (MIx)" with a predecessor of "Radeon Instinct," indicating a data center compute lineage.

The NVIDIA RTX 5000 Mobile Ada Generation is a mobile graphics processor: 120 W TDP, IGP form factor, portable device dependent display outputs, full DirectX 12 Ultimate support, and 76 ray tracing cores. Its 16 GB GDDR6 memory on a 256-bit bus is far smaller, but its pixel rate of 236.9 GPixel/s and 112 ROPs enable rasterized rendering. Its recorded 3DMark Steel Nomad DX12 score of 3596 places it at the 21st percentile, nearly tied with the GeForce GT 545.

The choice between these two follows from the workload. For compute-focused applications that require massive memory capacity and FP32 throughput, the MI325X is the only option with the recorded specifications to support such tasks. For graphics rendering, ray tracing, and mobile deployment, the RTX 5000 Mobile Ada Generation is the only one of the two with the necessary display outputs, API support, and ROP count. The 1000 W TDP of the MI325X demands infrastructure that the 120 W mobile NVIDIA part does not, so system integration constraints will drive most decisions. Neither part has a recorded benchmark result that directly compares them; the database contains no head-to-head entries, so any performance judgment must be inferred from the specification differences outlined above.
