AMD Radeon Instinct MI300A vs NVIDIA GeForce RTX 5070 SUPER Comparison

AMD Radeon Instinct MI300A and NVIDIA GeForce RTX 5070 SUPER are two entirely different classes of hardware. The MI300A is a data center accelerator with a massive memory pool, while the RTX 5070 SUPER is a consumer graphics card with a standard display output set. The database contains no direct head-to-head benchmark results for these two products, so the comparison relies on their recorded specifications and the single available benchmark score for the RTX 5070 SUPER.

Head-to-Head Benchmarks

The database shows no shared benchmark tests between the AMD Radeon Instinct MI300A and the NVIDIA GeForce RTX 5070 SUPER. The MI300A has an average benchmark score of 0 and no recorded entries, while the RTX 5070 SUPER has one entry: 3DMark Steel Nomad DX12, where it scores 2690. This score places the RTX 5070 SUPER at the 18th percentile of all GPUs in the database.

Looking at the RTX 5070 SUPER's nearest rivals in that test, the data shows a tight cluster. The NVIDIA Quadro K1100M scores 2664, which is 1% lower than the RTX 5070 SUPER. The NVIDIA GeForce GT 1030 scores 2662, a 1.1% deficit. The Intel Arc Pro B50 also scores 2660, trailing by 1.1%. The NVIDIA GeForce GT 440 scores 2645, which is 1.7% behind. These deltas are all small, indicating that the RTX 5070 SUPER's 2690 score is only marginally ahead of older, much less powerful hardware in this specific workload.

For the MI300A, there are no benchmark scores to interpret. The data shows a percentile rank of 50, but this is based on no recorded average score. The FP32 throughput is listed as 81.72 TFLOPS, and the FP16 throughput is 653.7 TFLOPS (8:1). The RTX 5070 SUPER delivers 32.15 TFLOPS for both FP32 and FP16. These raw compute figures suggest the MI300A has a substantial theoretical advantage in raw arithmetic throughput, but without benchmark results, no direct comparison of real-world performance can be made from this data.

The memory bandwidth figures further illustrate the gap. The MI300A has 10.3 TB/s of bandwidth from its HBM3 memory, while the RTX 5070 SUPER has 672.0 GB/s from GDDR7. That is a difference of roughly 15 times in favor of the MI300A, but it reflects different memory architectures and purposes rather than a head-to-head result.

The Verdict

Based strictly on the recorded data, the AMD Radeon Instinct MI300A is designed for compute-heavy data center workloads. Its 192 GB of HBM3 memory, 8192-bit memory bus, and 81.72 TFLOPS FP32 performance indicate a focus on large-scale processing tasks where memory capacity and throughput are critical. The RTX 5070 SUPER, with its 18 GB GDDR7 memory and 32.15 TFLOPS, targets consumer graphics and rendering.

The RTX 5070 SUPER has a recorded benchmark score of 2690 in 3DMark Steel Nomad DX12, placing it at the 18th percentile. Its nearest rivals in that test are older, lower-tier cards like the Quadro K1100M and GT 1030, with deltas of 1% to 1.7%. This suggests that in this particular DX12 test, the RTX 5070 SUPER does not significantly outperform those older products.

For the MI300A, the absence of any benchmark scores means the database offers no evidence of its real-world performance. The specification sheet shows a 750 W TDP, a PCIe 5.0 x16 interface, and no display outputs, confirming it is not intended for typical desktop use. The RTX 5070 SUPER has a 275 W TDP, a dual-slot design, and display outputs including 1x HDMI 2.1b and 3x DisplayPort 2.1b, making it suitable for standard systems.

Users who need a data center accelerator with high memory capacity and raw FP32 throughput would select the MI300A based on its specifications. Users who need a consumer GPU with display outputs and a recorded benchmark score would select the RTX 5070 SUPER. The data does not support a direct performance comparison between the two.
