AMD Instinct MI300A vs NVIDIA GeForce RTX 5070 SUPER Comparison

Where Each One Wins

The AMD Instinct MI300A and NVIDIA GeForce RTX 5070 SUPER occupy completely different positions in the hardware landscape, and the recorded data makes that split unambiguous. The MI300A is an accelerator module with no display outputs, no graphics API support, and a pixel rate of 0 MPixel/s. It is not designed for any rasterization workload. Its entire profile points toward compute acceleration: a 5 nm chip with 153,000 million transistors, 128 GB of HBM3 memory on an 8192-bit bus, and 5.32 TB/s of memory bandwidth. The RTX 5070 SUPER, by contrast, is a dual-slot graphics card with a 245 mm length, 1x HDMI 2.1b and 3x DisplayPort 2.1b outputs, DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. It is a rendering device first, compute device second.

The MI300A wins in raw compute scale. Its FP32 throughput is 61.29 TFLOPS, nearly double the 32.15 TFLOPS of the RTX 5070 SUPER. Its texture rate is 1,915.2 GTexel/s against 502.4 GTexel/s, a 3.8x advantage. Its memory subsystem dwarfs the NVIDIA card: 128 GB versus 18 GB, 8192-bit versus 192-bit, and 5.32 TB/s versus 672.0 GB/s. The MI300A also has far more shading units: 14,592 versus 6,400. The NVIDIA card does have 80 ROPs and 50 RT cores, while the MI300A has zero ROPs and no RT cores, but the AMD module compensates with 912 TMUs.

The RTX 5070 SUPER wins in every graphics-oriented metric. It delivers 201.0 GPixel/s, whereas the MI300A delivers 0 MPixel/s. The NVIDIA card has a full API stack: DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The MI300A lists N/A for all three. The RTX 5070 SUPER has a boost clock of 2512 MHz versus 2100 MHz on the MI300A, and its base clock of 2325 MHz exceeds the AMD module's boost clock. It also has a far lower power draw at 275 W versus 750 W, a 16-pin power connector versus no connectors on the OAM module, and a dual-slot form factor versus the OAM Module slot width.

The benchmark data available for the RTX 5070 SUPER shows a 3DMark Steel Nomad DX12 score of 2690. That score places it at the 18th percentile among all GPUs in the database. Its nearest rivals are the NVIDIA Quadro K1100M at 2664 (1% behind), the NVIDIA GeForce GT 1030 at 2662 (1.1% behind), the Intel Arc Pro B50 at 2660 (1.1% behind), and the NVIDIA GeForce GT 440 at 2645 (1.7% behind). The MI300A has no recorded benchmark entries and a percentile of 50 with an average score of 0, meaning the database contains no comparable performance measurements for it. The head-to-head benchmark list is empty, with zero wins for either side.

The Verdict

The data indicates that these two products should never be considered alternatives for the same task. The AMD Instinct MI300A is a compute accelerator with no graphics capability whatsoever. It has no display outputs, no graphics API support, and a pixel rate of zero. Its 128 GB HBM3 memory, 5.32 TB/s bandwidth, and 61.29 TFLOPS FP32 performance target large-scale compute workloads that require massive memory capacity and throughput. The RTX 5070 SUPER is a consumer graphics card with full rendering capabilities, display outputs, and a complete API stack.

For anyone building a rendering workstation or gaming system, the RTX 5070 SUPER is the only viable choice from the recorded data. It has 80 ROPs, 50 RT cores, 201.0 GPixel/s pixel throughput, and DirectX 12 Ultimate support. The MI300A cannot output any image, so it is useless for graphics tasks. For high-performance compute, the MI300A offers 128 GB of memory versus 18 GB, a 7.1x capacity advantage, and 5.32 TB/s versus 672.0 GB/s, a 7.9x bandwidth advantage. Its FP32 throughput is 1.9x higher, and its texture rate is 3.8x higher.

The RTX 5070 SUPER's benchmark percentile of 18 indicates that its Steel Nomad score of 2690 sits below most recorded GPUs in the database. Its nearest rivals are all older or lower-tier cards, with deltas between 1% and 1.7%. The MI300A's percentile of 50 with no benchmark data means the database treats it as an unknown quantity for gaming workloads, which is consistent with its complete lack of graphics hardware.

The power characteristics also separate the two. The MI300A requires 750 W and a suggested PSU of 1150 W, while the RTX 5070 SUPER draws 275 W. The MI300A uses an OAM Module slot width with no power connectors, indicating a server-style installation, while the RTX 5070 SUPER uses a 16-pin connector in a dual-slot consumer form factor. The release dates differ substantially: the MI300A launched on 2023-12-05, while the RTX 5070 SUPER is dated 2025-12-31 and listed as Active in production.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results between the AMD Instinct MI300A and the NVIDIA GeForce RTX 5070 SUPER. The wins count is zero for both sides, and the headToHeadBenchmarks array is empty. The only direct comparison available comes from the recorded specifications, which show a complete functional divergence rather than a competitive overlap.

The largest specification win for the MI300A is memory bandwidth. At 5.32 TB/s, it exceeds the RTX 5070 SUPER's 672.0 GB/s by a factor of 7.9. Memory capacity follows: 128 GB versus 18 GB, a 7.1x advantage. The FP32 compute rate of 61.29 TFLOPS is 1.9x the 32.15 TFLOPS of the NVIDIA card. The texture rate of 1,915.2 GTexel/s is 3.8x the 502.4 GTexel/s. The transistor count of 153,000 million is 4.9x the 31,100 million on the RTX 5070 SUPER, and the die size of 1017 mm² is 3.9x the 263 mm².

The RTX 5070 SUPER wins in pixel throughput, where it produces 201.0 GPixel/s against the MI300A's 0 MPixel/s. It also has higher clocks: a base of 2325 MHz versus 1000 MHz, and a boost of 2512 MHz versus 2100 MHz. The NVIDIA card has 50 RT cores and 200 tensor cores, while the MI300A lists null for both. The RTX 5070 SUPER has 80 ROPs versus zero on the MI300A. Its FP16 performance is 32.15 TFLOPS with a 1:1 ratio, while the MI300A lists null.

The RTX 5070 SUPER's only recorded benchmark, 3DMark Steel Nomad DX12 at 2690, shows it outperforming its nearest rivals by small margins: 1% over the Quadro K1100M, 1.1% over the GT 1030, 1.1% over the Intel Arc Pro B50, and 1.7% over the GT 440. These are all older or entry-level cards, which reinforces that the RTX 5070 SUPER is not a high-end performer relative to the full database, sitting at the 18th percentile.
