AMD Radeon Instinct MI300A vs NVIDIA GeForce RTX 5070 Mobile Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Radeon Instinct MI300A and the NVIDIA GeForce RTX 5070 Mobile. The MI300A has no recorded benchmark scores, an average benchmark score of 0, and no nearest rivals listed. The RTX 5070 Mobile, by contrast, has a full set of recorded measurements across nine different tests. This absence of comparable data is itself the most significant finding: the two products occupy entirely different measurement categories, and any comparison must be built from their architectural records rather than from matched test runs.

For the RTX 5070 Mobile, the recorded data shows a percentile ranking of 75 against all GPUs in the database. Its average benchmark score is 29,928. The nearest rival measurements place it in a tightly clustered competitive band: the NVIDIA GeForce RTX 3070 Ti scores 29,945, a delta of -0.1 percent relative to the 5070 Mobile, meaning the 5070 Mobile trails that card by a negligible margin. The NVIDIA GeForce RTX 2080 Ti scores 29,783, which is 0.5 percent lower, indicating the 5070 Mobile holds a slim advantage. The AMD Radeon RX 6800 scores 30,095, putting it 0.6 percent ahead of the 5070 Mobile. The AMD Radeon RX 6700 scores 30,433, leading by 1.7 percent. These deltas, all within roughly two percentage points, place the 5070 Mobile in a performance tier where no single rival dominates by a meaningful margin.

The individual benchmark scores for the 5070 Mobile show its strongest showing in Geekbench OpenCL at 122,238, followed by Geekbench Vulkan at 116,960. Passmark 3D Graphics (G3D) records 20,355, and Passmark GPU Compute records 8,279. The DirectX tests are considerably lower: DirectX 9 scores 214, DirectX 11 scores 192, DirectX 10 scores 129, and DirectX 12 scores 93. The 2D graphics test records 896. The gap between the compute-oriented Geekbench results and the DirectX results suggests the 5070 Mobile's architecture favors general compute workloads over legacy graphics API paths, a pattern consistent with its Blackwell 2.0 design.

The MI300A, lacking any recorded benchmarks, cannot be positioned against these numbers. Its only percentile figure is 50, which is the database's default neutral placement for an unmeasured product. The data confirms the MI300A was never subjected to the same test suite, so no head-to-head wins can be assigned to either product. The wins counter in the database reads 0 for both.

Where Each One Wins

Based on recorded data, the NVIDIA GeForce RTX 5070 Mobile wins in every measurable category, simply because it is the only one of the two with any benchmark results. Its wins are not relative to the MI300A, however, but relative to its own nearest rivals. Against those rivals, the 5070 Mobile shows a mixed picture. It edges past the RTX 2080 Ti by 0.5 percent, but falls behind the RTX 3070 Ti by 0.1 percent, the RX 6800 by 0.6 percent, and the RX 6700 by 1.7 percent. This places it as a mid-pack performer in its own tier, neither the fastest nor the slowest among comparable cards.

The MI300A has no recorded wins in any application category. Its architectural specifications suggest where it would be intended to compete, but the database provides no measured evidence of performance. The texture rate of 2,553.6 GTexel/s and FP32 throughput of 81.72 TFLOPS are raw specification figures, not benchmark outcomes, and they cannot be compared to the 5070 Mobile's 205.2 GTexel/s and 13.13 TFLOPS without test data to confirm real-world behavior.

The use-case split is therefore one-sided in the data: the 5070 Mobile is the only product with empirical results, and its profile indicates a card suited to compute-heavy workloads (Geekbench OpenCL at 122,238) and general 3D rendering (Passmark G3D at 20,355), with weaker legacy DirectX performance. The MI300A's role must be inferred entirely from its specifications, which point toward data center compute rather than client graphics, but no benchmark confirms this inference.

The Verdict

The data does not support a direct performance verdict between these two products because the MI300A has no benchmark measurements. The only defensible statement is that the RTX 5070 Mobile is a measured, mid-tier mobile GPU with an average score of 29,928 and a 75th percentile ranking, while the MI300A is an unmeasured data center module. Any user selecting between them would be choosing between a product with verified performance data and one with none.

From the recorded specifications, the MI300A is built for a different category entirely. It uses an OAM Module slot width, has no display outputs, and consumes 750 W, which classifies it as an accelerator rather than a client graphics card. The 5070 Mobile is an IGP with portable device dependent outputs and a 50 W power draw. These are not competing products in the conventional sense. The verdict, strictly from the data, is that the 5070 Mobile is the only one with benchmark evidence, and the MI300A's selection would require trusting its specification sheet without any measured validation.

For the 5070 Mobile specifically, the nearest rival data shows it is a competent performer within one to two percent of four established desktop cards. Its 0.5 percent advantage over the RTX 2080 Ti is its only positive delta, while its 1.7 percent deficit to the RX 6700 is its largest gap. A buyer choosing among these five cards would find no clear winner, as the entire spread is under two percent.
