AMD Instinct MI308X vs NVIDIA GeForce RTX 4070 Ti SUPER Comparison

The Verdict

The AMD Instinct MI308X and NVIDIA GeForce RTX 4070 Ti SUPER occupy entirely different segments of the hardware landscape, and the recorded data reflects that split clearly. The MI308X is a compute-oriented accelerator built around the CDNA 3.0 architecture, with no display outputs, no DirectX support, no OpenGL support, and no Vulkan support. It is designed for data center workloads where graphics output is irrelevant and raw throughput is paramount. The RTX 4070 Ti SUPER, by contrast, is a conventional consumer graphics card from the GeForce 40-series, with full API compatibility including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, plus a triple-slot cooler and a 16-pin power connector.

The data indicates that the MI308X has no benchmark entries in the database, no average score, and a percentile rank of 50 against all GPUs. The RTX 4070 Ti SUPER has a substantial set of recorded benchmark results, an average score of 31087, and a percentile rank of 76. Anyone selecting between these two parts should base the decision on workload type, not on comparative gaming or graphics performance, because the MI308X simply does not participate in the same test categories. The RTX 4070 Ti SUPER is the only one of the two that can render frames, output to a display, or run a graphics API workload. The MI308X is the only one of the two that carries 192 GB of HBM3 memory and a 5.32 TB/s memory bandwidth figure, positioning it for large-scale compute tasks.

Where Each One Wins

The RTX 4070 Ti SUPER wins in every recorded benchmark category, simply because it is the only part with benchmark results in the database. Its PassMark G3D score is 31811, its PassMark G2D score is 1225, and its Geekbench OpenCL score is 199267. The MI308X has zero recorded benchmarks, so there is no direct head-to-head data to compare. The wins for the NVIDIA card are therefore absolute across all tested workloads, but this is a function of database coverage rather than an indication of architectural superiority in compute tasks.

The MI308X wins in the specifications that matter for memory-bound and throughput-bound compute. It offers 192 GB of memory versus 16 GB, an 8192-bit bus versus 256-bit, and 5.32 TB/s of bandwidth versus 672.3 GB/s. Its FP32 throughput of 81.72 TFLOPS doubles the 44.10 TFLOPS of the RTX 4070 Ti SUPER. Its texture rate of 2,553.6 GTexel/s is roughly 3.7 times the 689.0 GTexel/s of the NVIDIA card. For workloads that can use HBM3 capacity and bandwidth, such as large model inference or scientific simulation, the MI308X is the clear choice. For any workload that requires graphics output, ray tracing, or standard consumer API support, the RTX 4070 Ti SUPER is the only viable option.

Architecture Differences

The MI308X uses the Aqua Vanjaram chip, built on CDNA 3.0 architecture, manufactured on a 5 nm process at TSMC. It packs 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million per square millimeter. The RTX 4070 Ti SUPER uses the AD103 chip, built on Ada Lovelace architecture, also on a 5 nm TSMC process, but with 45,900 million transistors on a 379 mm² die, for a density of 121.1 million per square millimeter. The MI308X is a much larger and denser chip, reflecting its data center focus.

The MI308X has 19,456 shading units and 1,216 texture mapping units, but zero ROPs and a pixel rate of 0 MPixel/s. It has no ray tracing cores and no tensor cores listed in the database. Its FP16 throughput matches FP32 at 81.72 TFLOPS, indicating a 1:1 ratio. The RTX 4070 Ti SUPER has 8,448 shading units, 264 TMUs, 96 ROPs, 66 ray tracing cores, and 264 tensor cores. Its pixel rate is 250.6 GPixel/s, and its FP16 throughput also matches FP32 at 44.10 TFLOPS. The NVIDIA card is a full graphics processor with fixed-function units for rasterization and ray tracing, while the AMD card omits these entirely.

Memory architecture differs drastically. The MI308X uses 192 GB of HBM3 on an 8192-bit bus, with a memory clock of 1300 MHz and 5.2 Gbps effective, producing 5.32 TB/s of bandwidth. The RTX 4070 Ti SUPER uses 16 GB of GDDR6X on a 256-bit bus, with a memory clock of 1313 MHz and 21 Gbps effective, producing 672.3 GB/s of bandwidth. The MI308X has no display outputs and no power connectors, relying on an OAM module slot for power delivery. The RTX 4070 Ti SUPER has a triple-slot cooler, a 16-pin power connector, and outputs including HDMI 2.1 and three DisplayPort 1.4a connections.
