AMD Instinct MI350X vs NVIDIA GeForce RTX 4070 Max-Q Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Instinct MI350X or the NVIDIA GeForce RTX 4070 Max-Q. Both entries list an average benchmark score of 0 and hold a 50th percentile position against all GPUs, which indicates that no standardized test results have been submitted for these parts. Consequently, direct numerical comparisons of performance, such as frame rates or compute throughput, cannot be derived from the measured data. What follows is a structural and architectural analysis based solely on the recorded specifications, not on empirical testing.

The absence of benchmark data means that the headline figures, such as the MI350X's FP32 throughput of 72.09 TFLOPS and the RTX 4070 Max-Q's 11.34 TFLOPS, represent theoretical peak rates from the specification sheets, not measured outcomes. Similarly, memory bandwidth figures of 8.19 TB/s for the MI350X and 256.0 GB/s for the RTX 4070 Max-Q are design specifications. The data shows that the MI350X holds a massive theoretical advantage in raw compute and memory bandwidth, but without benchmark scores, the real-world implications of these numbers remain unquantified in the database.

Architecture Differences

The MI350X is built on the CDNA 4.0 architecture, designed for compute acceleration, while the RTX 4070 Max-Q uses Ada Lovelace, aimed at graphics and ray tracing. The MI350X belongs to the Instinct (MIx) generation, and the RTX 4070 Max-Q belongs to the GeForce 40 Mobile generation. The MI350X's chip is designated MI350 256CU, and the RTX 4070 Max-Q uses the AD106 chip.

The MI350X has no ROPs, no RT cores, and no tensor cores recorded, and it lists no graphics API support. This aligns with its role as an accelerator without display output. The RTX 4070 Max-Q includes ROPs, RT cores, and tensor cores, and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The MI350X uses HBM3e memory, which is a stacked high-bandwidth design, while the RTX 4070 Max-Q uses GDDR6, a conventional graphics memory.

The MI350X's transistor density is 77.7M per mm², while the RTX 4070 Max-Q achieves 121.8M per mm². Despite the lower density, the MI350X's enormous die size allows for far more total transistors.

The MI350X's memory clock is 2000 MHz with 8 Gbps effective, while the RTX 4070 Max-Q's is 2000 MHz with 16 Gbps effective, indicating different memory technology characteristics.

The Verdict

The data presents two products with no overlap in purpose. The AMD Instinct MI350X is a compute accelerator with 72.09 TFLOPS of FP32 performance, 288 GB of HBM3e memory, and 8.19 TB/s of bandwidth, housed in an OAM Module with a 1000 W TDP. It has no display outputs, no graphics API support, and no ROPs, RT cores, or tensor cores. This is a server-oriented part for workloads that demand massive parallel throughput and memory capacity.

The NVIDIA GeForce RTX 4070 Max-Q is a mobile graphics processor with 11.34 TFLOPS of FP32 performance, 8 GB of GDDR6 memory, and 256.0 GB/s of bandwidth, contained in an IGP slot with a 35 W TDP. It includes 36 RT cores, 144 tensor cores, 48 ROPs, and full support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. This is a low-power part for laptops that need conventional rendering and ray tracing.

The recorded specifications show that the MI350X outperforms the RTX 4070 Max-Q in every raw compute and memory metric, but it does so without any graphics capability. The RTX 4070 Max-Q wins in every graphics-specific metric, including pixel rate, ROP count, and API support. A user selecting between these would choose the MI350X for compute tasks such as large-scale data processing or AI training, and the RTX 4070 Max-Q for real-time 3D rendering, gaming, or any workload requiring a display output. The absence of benchmark scores means the database cannot confirm how these theoretical advantages translate into actual application performance, but the architectural split is unambiguous.
