AMD Instinct MI300X vs NVIDIA GeForce RTX 4060 Max-Q Comparison

The Verdict

The AMD Instinct MI300X and NVIDIA GeForce RTX 4060 Max-Q occupy entirely different segments of the GPU landscape. The Instinct MI300X is a data center accelerator with a recorded Geekbench OpenCL score of 317,994, placing it in the 100th percentile of all GPUs in the database. The RTX 4060 Max-Q, a mobile integrated graphics processor for laptops, sits in the 50th percentile with no recorded benchmark scores in the database, making direct numerical comparison impossible based on recorded data alone.

The database shows the MI300X outperforms its nearest rivals in some cases: it is 7.5% ahead of the NVIDIA L40S and 10.7% ahead of the NVIDIA RTX 6000 Ada Generation. However, it trails the NVIDIA H200 NVL by 5% and the NVIDIA B200 by 8%. The RTX 4060 Max-Q has no nearest rivals listed, no average benchmark score, and no recorded test results, indicating the database lacks sufficient data to position it competitively.

For organizations deploying large-scale AI inference or training workloads, the MI300X delivers a top-tier OpenCL result with massive memory capacity. For laptop users seeking a low-power graphics solution, the RTX 4060 Max-Q offers established API support and a compact form factor, but the database does not quantify its performance. The verdict from the data is straightforward: the MI300X is a high-throughput accelerator with verified benchmark dominance, while the RTX 4060 Max-Q is a mobile part whose performance cannot be assessed from recorded measurements.

Where Each One Wins

The MI300X wins decisively in every recorded benchmark category because it is the only one of the two with any benchmark entries. Its Geekbench OpenCL score of 317,994 represents the sole quantitative performance data point. The RTX 4060 Max-Q has zero benchmarks in the database, meaning there are no wins recorded for it.

Looking at the MI300X's nearest rivals, the data shows specific victories. It beats the NVIDIA L40S by 7.5% and the NVIDIA RTX 6000 Ada Generation by 10.7%. These wins indicate strong OpenCL compute performance relative to competing data center accelerators. The losses to the H200 NVL (5% behind) and B200 (8% behind) show the MI300X is competitive but not the absolute fastest in its class.

In terms of specifications that translate to use cases, the MI300X offers 192 GB of HBM3 memory with 5.32 TB/s bandwidth, making it suitable for large model workloads. The RTX 4060 Max-Q has 8 GB of GDDR6 memory with 256.0 GB/s bandwidth, positioning it for conventional laptop graphics. The MI300X has no display outputs, confirming its role as a compute-only accelerator, while the RTX 4060 Max-Q has portable device dependent outputs, confirming its role in mobile systems.

The RTX 4060 Max-Q wins on power efficiency based on the recorded TDP figures: 35 W versus 750 W for the MI300X. It also supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI300X has no API support listed. For gaming or consumer graphics applications, the RTX 4060 Max-Q is the only viable option.
