AMD Instinct MI300 vs NVIDIA GeForce RTX 5070 SUPER Comparison

AMD Instinct MI300 and NVIDIA GeForce RTX 5070 SUPER occupy different corners of the hardware landscape, one built as a dense compute accelerator and the other as a consumer graphics card. The recorded data shows no shared benchmark suite, but the specification sheets reveal distinct design philosophies and intended workloads. The MI300 is a massive data-center processor, while the RTX 5070 SUPER is a compact, display-equipped consumer card.

Where Each One Wins

The AMD Instinct MI300 wins on raw compute throughput and memory capacity. Its FP32 output is 47.87 TFLOPS, which is 49% higher than the RTX 5070 SUPER’s 32.15 TFLOPS. FP16 performance also sits at 47.87 TFLOPS with 1:1 ratio, meaning the MI300 handles half-precision workloads at the same rate as single-precision, a trait suited for AI training and scientific simulation. The MI300’s texture rate of 1,496.0 GTexel/s is nearly triple the RTX 5070 SUPER’s 502.4 GTexel/s, indicating a strong advantage in texture-heavy compute tasks.

The MI300 also dominates memory specifications. It carries 128 GB of HBM3 on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The RTX 5070 SUPER has 18 GB of GDDR7 on a 192-bit bus, yielding 672.0 GB/s. That difference is not marginal; the MI300 provides nearly 8 times the memory bandwidth, a decisive factor for large datasets that exceed the RTX card’s capacity.

The NVIDIA GeForce RTX 5070 SUPER wins where consumer features matter. It has display outputs: 1x HDMI 2.1b and 3x DisplayPort 2.1b, while the MI300 has no outputs. The RTX card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, whereas the MI300 reports N/A for all three APIs. The RTX 5070 SUPER also has 50 RT cores and 200 tensor cores, features absent from the MI300’s specification sheet. Its pixel rate of 201.0 GPixel/s, compared to the MI300’s 0 MPixel/s, confirms the NVIDIA card is built for rendering to a screen.

The RTX 5070 SUPER wins on efficiency in terms of power. Its TDP is 275 W versus the MI300’s 600 W, meaning the consumer card delivers its 32.15 TFLOPS while drawing less than half the power. The MI300 needs a 1000 W suggested PSU and dual 8-pin connectors, while the RTX card uses a single 16-pin connector.

Architecture Differences

The MI300 uses the CDNA 3.0 architecture, specifically designed for compute acceleration. Its chip is codenamed Aqua Vanjaram, fabricated on TSMC’s 5 nm process. The die is enormous at 1017 mm², housing 153,000 million transistors, which gives a transistor density of 150.4M per mm². This is a data-center part with no display engine, no graphics API support, and no rendering pipeline.

The RTX 5070 SUPER uses Blackwell 2.0 architecture on the GB205 chip, also built on TSMC’s 5 nm process. Its die measures 263 mm², containing 31,100 million transistors, for a density of 118.3M per mm². The smaller die and lower transistor count reflect a consumer-oriented design that balances cost, power, and packaging. The RTX card includes dedicated RT cores and tensor cores, while the MI300 lists none.

Memory technology splits them further. The MI300 uses HBM3 stacked memory with an 8192-bit interface, allowing 5.32 TB/s bandwidth. The RTX 5070 SUPER uses GDDR7 on a 192-bit bus, reaching 672.0 GB/s. The MI300’s memory clock is listed as 1300 MHz with 5.2 Gbps effective, while the RTX card runs at 1750 MHz with 28 Gbps effective.

The MI300 has 14,080 shading units, 880 TMUs, and no ROPs. The RTX 5070 SUPER has 6,400 shading units, 200 TMUs, and 80 ROPs. The MI300’s lack of ROPs reinforces its role as a non-rendering accelerator. The RTX card’s 80 ROPs enable its 201.0 GPixel/s pixel rate, which the MI300 cannot match (0 MPixel/s).

Head-to-Head Benchmarks

No head-to-head benchmark results exist in the database for these two products. The RTX 5070 SUPER has a single recorded benchmark: 3dmark_3dmark_steel_nomad_dx12 with a score of 2690. Its nearest rivals in that test are the NVIDIA Quadro K1100M at 2664 (1% slower), NVIDIA GeForce GT 1030 at 2662 (1.1% slower), Intel Arc Pro B50 at 2660 (1.1% slower), and NVIDIA GeForce GT 440 at 2645 (1.7% slower). The MI300 has no benchmark scores, so its percentile ranking sits at 50 among all GPUs, while the RTX card ranks at the 18th percentile.

Without shared benchmarks, the data relies on specification-derived comparisons. The MI300’s FP32 of 47.87 TFLOPS is 49% above the RTX card’s 32.15 TFLOPS, a clear lead in raw compute. The MI300’s texture rate of 1,496.0 GTexel/s is 197% higher than the RTX card’s 502.4 GTexel/s. Memory bandwidth shows the largest gap: 5.32 TB/s versus 672.0 GB/s, an 8-fold advantage for the MI300.

The RTX 5070 SUPER counters with its pixel rate of 201.0 GPixel/s versus 0 MPixel/s, indicating it can rasterize frames while the MI300 cannot. The RTX card also has a higher base clock (2325 MHz versus 1000 MHz) and boost clock (2512 MHz versus 1700 MHz), which benefits latency-sensitive consumer tasks. The MI300’s larger transistor count (153,000 million versus 31,100 million) and die size (1017 mm² versus 263 mm²) show the scale of its compute resources.

The Verdict

The data indicates two different purchasing contexts. For compute-heavy workloads that require massive memory capacity and bandwidth, the AMD Instinct MI300 is the clear choice. Its 128 GB HBM3 pool and 5.32 TB/s bandwidth allow processing datasets that would never fit in the RTX card’s 18 GB GDDR7 memory. Its FP32 output of 47.87 TFLOPS exceeds the RTX card by 49%, and its texture rate of 1,496.0 GTexel/s is nearly three times higher. The MI300’s 600 W TDP and 1000 W suggested PSU reflect the cost of that capability, but for a server rack, that is a known trade-off.

For consumer graphics, gaming, and any workload requiring a display, the NVIDIA GeForce RTX 5070 SUPER is the only option between these two. It has HDMI and DisplayPort outputs, full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. Its 50 RT cores and 200 tensor cores enable ray tracing and AI-accelerated features that the MI300 does not provide. Its 201.0 GPixel/s pixel rate confirms rendering capability, while the MI300’s pixel rate is zero. The RTX card also runs at higher clocks (2325 MHz base, 2512 MHz boost) and draws less than half the power of the MI300.

The percentile rankings reflect their respective positions: the RTX 5070 SUPER sits at the 18th percentile among all GPUs based on its single 3DMark score of 2690, while the MI300 has no benchmark data and rests at the 50th percentile by default. The absence of shared benchmarks means direct performance comparison is limited, but the specification deltas are large enough to guide a decision. The MI300 is for computation without graphics. The RTX 5070 SUPER is for graphics without compute at the MI300’s scale.
