AMD Instinct MI300X vs NVIDIA GeForce RTX 4070 Max-Q Comparison

Head-to-Head Benchmarks

The recorded data contains a single benchmark result for the AMD Instinct MI300X, the Geekbench OpenCL score of 317,994. This places the MI300X at the 100th percentile among all GPUs in the database, indicating it outperforms all other recorded graphics processors in this specific test. The NVIDIA GeForce RTX 4070 Max-Q has no benchmark entries in the database, so its average benchmark score is recorded as zero and its percentile ranking sits at the 50th mark. With no head-to-head benchmark entries and no wins recorded for either product, the comparative analysis relies entirely on the nearest rival data provided for the MI300X.

The MI300X’s nearest rivals in the database reveal its competitive positioning. The NVIDIA H200 NVL records an average score of 334,891, which is 5% higher than the MI300X’s average of 317,994. The NVIDIA B200 achieves 345,482, an 8% advantage over the MI300X. Conversely, the NVIDIA L40S scores 295,763, placing it 7.5% behind the MI300X, and the NVIDIA RTX 6000 Ada Generation scores 287,237, which is 10.7% lower. These figures indicate that the MI300X sits in the upper tier of the database’s recorded accelerators, trailing only the highest-end NVIDIA data center parts while leading other professional workstation GPUs by a meaningful margin.

The GeForce RTX 4070 Max-Q, by contrast, has no recorded benchmark scores and no rival comparisons available. Its percentile ranking of 50 suggests it represents a mid-range position in the overall distribution of all GPUs, but without concrete scores, the database cannot quantify its performance relative to the MI300X or any other product. The data shows a clear asymmetry: one product has extensive performance metrics and rival context, while the other has no measurable benchmark presence.

The Verdict

The data presents a straightforward case for the AMD Instinct MI300X as the performance leader. Its Geekbench OpenCL score of 317,994 places it at the 100th percentile, meaning it outperforms every other GPU in the database on this metric. The nearest rival comparisons reinforce this: the MI300X is 7.5% ahead of the NVIDIA L40S and 10.7% ahead of the NVIDIA RTX 6000 Ada Generation. Only the NVIDIA H200 NVL and B200 exceed its score, by 5% and 8% respectively.

The NVIDIA GeForce RTX 4070 Max-Q has no benchmark data, making any direct performance comparison impossible from the recorded information. Its 50th percentile ranking suggests it falls in the middle of the database’s GPU population, but no score supports a quantitative claim. For anyone selecting a GPU strictly on the basis of recorded benchmark performance, the MI300X is the only product with verified results, and those results are exceptional.

The RTX 4070 Max-Q may still be relevant for its intended mobile use case, but the database provides no evidence of its performance level. The MI300X, with its 100th percentile standing, is the clear choice for compute workloads where OpenCL performance is a primary criterion. The data does not support any performance advantage for the RTX 4070 Max-Q, as no measurements exist for it.

Architecture Differences

The two GPUs originate from different design philosophies. The AMD Instinct MI300X uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, built on a 5 nm process at TSMC. It integrates 153,000 million transistors on a die size of 1017 mm², yielding a transistor density of 150.4 million per mm². The NVIDIA GeForce RTX 4070 Max-Q uses the Ada Lovelace architecture on the AD106 chip, also fabricated on a 5 nm process at TSMC, but with 22,900 million transistors on a 188 mm² die, resulting in a density of 121.8 million per mm².

The MI300X is designed as a data center accelerator with no display outputs and no API support for DirectX, OpenGL, or Vulkan. It uses an OAM module slot width, has no power connectors, and draws a TDP of 750 W with a suggested PSU of 1150 W. The RTX 4070 Max-Q is a mobile integrated graphics processor with a 35 W TDP, an IGP slot width, no power connectors, and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its display outputs are listed as portable device dependent, reflecting its laptop-oriented design.

Memory architecture differs substantially. The MI300X carries 192 GB of HBM3 memory on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The RTX 4070 Max-Q has 8 GB of GDDR6 memory on a 128-bit bus, providing 256.0 GB/s. The MI300X’s memory clock is 1300 MHz with 5.2 Gbps effective, while the RTX 4070 Max-Q runs at 2000 MHz with 16 Gbps effective. The MI300X’s bus width and total memory capacity are far larger, reflecting its compute-oriented role.

Compute resources also differ. The MI300X contains 19,456 shading units, 1,216 TMUs, and no ROPs, with a pixel rate of 0 MPixel/s and a texture rate of 2,553.6 GTexel/s. It delivers 81.72 TFLOPS for both FP32 and FP16 (1:1). The RTX 4070 Max-Q has 4,608 shading units, 144 TMUs, and 48 ROPs, with a pixel rate of 59.04 GPixel/s and a texture rate of 177.1 GTexel/s. It also delivers 11.34 TFLOPS for FP32 and FP16 (1:1), but adds 36 ray tracing cores and 144 tensor cores, features the MI300X lacks.
