AMD Radeon Instinct MI300 vs NVIDIA GeForce RTX 5070 SUPER Comparison

Where Each One Wins

The recorded data places these two accelerators in entirely different segments of the GPU landscape. The AMD Radeon Instinct MI300 is a data center compute accelerator with no display outputs, while the NVIDIA GeForce RTX 5070 SUPER is a consumer graphics card with full display connectivity. Their benchmark profiles reflect this split.

The AMD Radeon Instinct MI300 shows no recorded benchmark entries in the database, and its percentile ranking against all GPUs sits at 50. The NVIDIA GeForce RTX 5070 SUPER has one recorded benchmark result: a 3DMark Steel Nomad DX12 score of 2690, placing it in the 18th percentile against all GPUs. The head-to-head benchmark table is empty, meaning no direct comparative tests exist between these two products.

The MI300 wins on raw compute specifications. Its FP32 throughput is 47.87 TFLOPS, compared to 32.15 TFLOPS for the RTX 5070 SUPER. In FP16, the MI300 delivers 383.0 TFLOPS (8:1 ratio), while the RTX 5070 SUPER delivers 32.15 TFLOPS (1:1 ratio). The MI300 also holds a massive memory advantage: 128 GB of HBM3 across an 8192-bit bus, providing 6.55 TB/s of bandwidth. The RTX 5070 SUPER has 18 GB of GDDR7 on a 192-bit bus, yielding 672.0 GB/s.

The RTX 5070 SUPER wins on architectural completeness for graphics workloads. It includes 50 RT cores and 200 tensor cores, features entirely absent from the MI300's specification sheet. Its pixel rate is 201.0 GPixel/s, while the MI300 is recorded at 0 MPixel/s. The RTX 5070 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4; the MI300 lists no API support. The RTX 5070 SUPER also has a lower power draw at 275 W versus 600 W for the MI300.

The data indicates the MI300 is optimized for compute density and memory capacity, whereas the RTX 5070 SUPER is positioned for real-time graphics rendering and API compatibility. The MI300's 14080 shading units and 880 texture mapping units dwarf the RTX 5070 SUPER's 6400 shading units and 200 TMUs. The MI300's texture rate reaches 1,496.0 GTexel/s, nearly three times the RTX 5070 SUPER's 502.4 GTexel/s.

Clock speeds also differ substantially. The MI300 runs at a 1000 MHz base and 1700 MHz boost. The RTX 5070 SUPER runs at 2325 MHz base and 2512 MHz boost. The RTX 5070 SUPER's higher clocks compensate somewhat for its smaller chip, but the MI300's sheer scale in transistor count, 153,000 million versus 31,100 million, defines its compute advantage.

The Verdict

The selection between these two products depends entirely on workload type. The AMD Radeon Instinct MI300 is a server accelerator with no display outputs, designed for compute tasks requiring massive memory capacity and FP16 throughput. Its 128 GB HBM3 memory and 6.55 TB/s bandwidth serve large data sets and high-performance computing workloads. The RTX 5070 SUPER, with its RT cores, tensor cores, and full display outputs, addresses graphics rendering, ray tracing, and DirectX 12 Ultimate applications.

Benchmark results indicate the RTX 5070 SUPER scores 2690 in 3DMark Steel Nomad DX12. Its nearest rivals in the database are the NVIDIA Quadro K1100M at 2664 (1% slower), the NVIDIA GeForce GT 1030 at 2662 (1.1% slower), the Intel Arc Pro B50 at 2660 (1.1% slower), and the NVIDIA GeForce GT 440 at 2645 (1.7% slower). These deltas are narrow, showing the RTX 5070 SUPER sits in a tight performance cluster in this particular test.

The MI300 has no benchmark scores in the database and no nearest rivals listed. Its percentile rank of 50 indicates it sits at the median of all GPUs in the database, but without recorded test results, direct performance comparison is impossible. The data shows two products with divergent design goals rather than direct competitors.

For compute-centric deployments requiring extensive memory and FP16 capability, the MI300's specifications dominate. For graphics-focused systems needing API support, display outputs, and hardware ray tracing, the RTX 5070 SUPER is the only one of the two with those capabilities. The power difference matters for deployment context: 600 W versus 275 W suggests different cooling and power delivery requirements.

Head-to-Head Benchmarks

The head-to-head benchmark table is empty. No direct comparative tests exist in the database for these two products. The only recorded benchmark is the RTX 5070 SUPER's 3DMark Steel Nomad DX12 score of 2690. The MI300 has no benchmark entries whatsoever.

The specification data provides indirect comparison points. The MI300's FP32 throughput of 47.87 TFLOPS exceeds the RTX 5070 SUPER's 32.15 TFLOPS by roughly 49%. In FP16, the MI300's 383.0 TFLOPS is nearly twelve times the RTX 5070 SUPER's 32.15 TFLOPS, though the 8:1 versus 1:1 ratio reflects different design priorities. The MI300's memory bandwidth of 6.55 TB/s is approximately 9.7 times the RTX 5070 SUPER's 672.0 GB/s.

Texture throughput shows the MI300's compute orientation: 1,496.0 GTexel/s versus 502.4 GTexel/s. The MI300 uses 14080 shading units against 6400 for the RTX 5070 SUPER. The RTX 5070 SUPER counters with 50 RT cores, 200 tensor cores, and an 80 ROP count, all absent or zeroed in the MI300's specifications.

The RTX 5070 SUPER's nearest rival comparisons show its modest standing in the database. A 1% lead over the Quadro K1100M, a 1.1% lead over the GT 1030 and Arc Pro B50, and a 1.7% lead over the GT 440 place it among entry-level performers in the 3DMark Steel Nomad test. The 18th percentile rank confirms this positioning against all GPUs in the database.

The MI300's 50th percentile rank, despite having no benchmark scores, suggests the database treats its specification-based classification separately from measured test results. Without head-to-head data, no direct win-loss record exists: winsA is 0 and winsB is 0.
