AMD Instinct MI308X vs NVIDIA GeForce RTX 5070 Ti Comparison

The Verdict

The recorded data presents two fundamentally different accelerators with almost no overlap in intended use. The AMD Instinct MI308X is a compute-oriented module with no display outputs, no graphics API support, and a 192 GB HBM3 frame buffer. The NVIDIA GeForce RTX 5070 Ti is a consumer graphics card with full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, plus HDMI and DisplayPort outputs. The data shows that the MI308X targets server-side acceleration workloads, while the RTX 5070 Ti targets desktop rendering and general-purpose compute. The MI308X carries no benchmark entries in the database, while the RTX 5070 Ti has an average benchmark score of 49957 and sits in the 86th percentile of all GPUs. The RTX 5070 Ti is the only one of the two with measurable graphics performance data, so any user needing a display output or a standard graphics API must choose the NVIDIA card. The MI308X, with 153,000 million transistors, a 1017 mm² die, and 5.32 TB/s of memory bandwidth, appears designed for memory-bound compute workloads, but the database contains no benchmark results to quantify its performance. The RTX 5070 Ti was released on 2025-02-19 with a launch MSRP of 749 USD, while the MI308X appeared on 2023-12-05 with no launch MSRP recorded.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results between the MI308X and the RTX 5070 Ti. The MI308X has no individual benchmark entries and an average benchmark score of 0. The RTX 5070 Ti has a full suite of recorded results. Its 3DMark Steel Nomad DX12 score is 6604. Geekbench OpenCL returns 212363, and Geekbench Vulkan returns 225122. Passmark results include DirectX 10 at 192, DirectX 11 at 300, DirectX 12 at 127, DirectX 9 at 351, G2D at 1332, G3D at 32974, and GPU Compute at 20203. The average benchmark score of 49957 places the RTX 5070 Ti in the 86th percentile of all GPUs. Its nearest rivals in the database are the AMD Radeon RX Vega 64 with an average score of 50001 and a delta of -0.1%, the Intel Arc A550M with 49737 and a delta of 0.4%, the AMD Radeon RX 6900 XT with 50951 and a delta of -2%, and the AMD Radeon RX 6800 XT with 48477 and a delta of 3.1%. These deltas show the RTX 5070 Ti performing within 3.1% of all four rivals, with a slight edge over the Arc A550M and a slight deficit against the RX Vega 64, RX 6900 XT, and RX 6800 XT. Since the MI308X has no benchmark data, no direct performance comparison can be made from the recorded measurements.

Where Each One Wins

The MI308X wins on raw compute and memory capacity based on its specification sheet. Its FP32 throughput of 81.72 TFLOPS is nearly double the RTX 5070 Ti's 43.94 TFLOPS, and its FP16 rate matches at 81.72 TFLOPS. The 192 GB HBM3 frame buffer with 5.32 TB/s bandwidth is 12 times the capacity and roughly 5.9 times the bandwidth of the RTX 5070 Ti's 16 GB GDDR7 at 896.0 GB/s. The 8192-bit memory bus is 32 times wider than the 256-bit bus on the NVIDIA card. The MI308X also has more than twice the shading units (19,456 versus 8,960) and more than four times the TMUs (1,216 versus 280). Its texture rate of 2,553.6 GTexel/s is 3.7 times the RTX 5070 Ti's 686.6 GTexel/s. These figures indicate a design optimized for memory-bound and throughput-heavy compute workloads, not for graphics rendering. The MI308X has no ROPs, no pixel rate, no RT cores, no tensor cores, and no graphics API support, confirming its role as a compute accelerator rather than a graphics card.

The RTX 5070 Ti wins on every graphics-oriented metric. It has 96 ROPs and a pixel rate of 235.4 GPixel/s, while the MI308X has zero ROPs and 0 MPixel/s. It includes 70 RT cores and 280 tensor cores, neither of which the MI308X lists. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI308X supports none. It provides display outputs, while the MI308X has none. Its benchmark results place it in the 86th percentile of all GPUs with an average score of 49957, and its nearest rivals all score within 3.1%, indicating competitive performance in the consumer graphics segment. The RTX 5070 Ti also demands less power at 300 W TDP versus 750 W, and its suggested PSU of 700 W is substantially lower than the 1150 W suggested for the MI308X. The RTX 5070 Ti's physical design as a dual-slot card with a 16-pin connector makes it installable in standard desktop systems, whereas the MI308X is an OAM module with no connectors listed. The recorded data shows the RTX 5070 Ti as the only option for users who need graphics output, standard API compatibility, or measurable gaming and workstation benchmark performance.
