AMD Radeon Instinct MI308X vs NVIDIA GeForce RTX 5070 SUPER Comparison

Where Each One Wins

The recorded data splits these two products into completely different roles. The AMD Radeon Instinct MI308X is a compute-oriented accelerator with no display outputs, no DirectX, OpenGL, or Vulkan support listed, and a 0 MPixel/s pixel rate. It is not designed to render frames. The NVIDIA GeForce RTX 5070 SUPER, by contrast, carries a full graphics feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, Vulkan 1.4, 80 ROPs, and a 201.0 GPixel/s pixel rate. The only benchmark score in the database belongs to the RTX 5070 SUPER, a 3DMark Steel Nomad DX12 result of 2690. The MI308X has no benchmark entries and an average score of 0.

The MI308X wins on raw memory capacity and bandwidth. It ships with 192 GB of HBM3 memory across an 8192-bit bus, delivering 10.3 TB/s of bandwidth. The RTX 5070 SUPER has 18 GB of GDDR7 on a 192-bit bus, for 672.0 GB/s. That is a 15.3x bandwidth advantage for the AMD part. The MI308X also leads in compute throughput: 81.72 TFLOPS FP32 versus 32.15 TFLOPS, and 653.7 TFLOPS FP16 (8:1) versus 32.15 TFLOPS FP16 (1:1). Texture rate favors AMD as well, 2,553.6 GTexel/s against 502.4 GTexel/s.

The RTX 5070 SUPER wins on clock speeds, efficiency, and graphics features. Its base clock is 2325 MHz and boost is 2512 MHz, against 1000 MHz base and 2100 MHz boost for the MI308X. The NVIDIA card draws 275 W while the AMD accelerator draws 750 W. The NVIDIA part also has a production status of Active, while the MI308X has no production status recorded. The RTX 5070 SUPER uses a Dual-slot form factor with a 16-pin power connector, while the MI308X is an OAM Module with no power connectors listed, meaning it relies on baseboard power delivery.

The data indicates a clean split: the MI308X is a data center compute accelerator built for memory-bound and FP16-heavy workloads, while the RTX 5070 SUPER is a client graphics card built for rasterization and DirectX 12 workloads. Neither product is a substitute for the other.

The Verdict

The database shows the MI308X is for compute tasks that need enormous memory capacity and bandwidth. Its 192 GB HBM3 pool, 10.3 TB/s bandwidth, and 653.7 TFLOPS FP16 throughput position it for large model training or inference workloads. It has no display outputs and no graphics API support, so it cannot drive a monitor or run game workloads. The RTX 5070 SUPER is for graphics work. It has a recorded 3DMark Steel Nomad DX12 score of 2690, places in the 18th percentile among all GPUs, and includes modern display outputs (1x HDMI 2.1b, 3x DisplayPort 2.1b). Its nearest rivals in the database are older or lower-end parts: the NVIDIA Quadro K1100M at 2664 (1% behind), the GeForce GT 1030 at 2662 (1.1% behind), the Intel Arc Pro B50 at 2660 (1.1% behind), and the GeForce GT 440 at 2645 (1.7% behind). The RTX 5070 SUPER is only narrowly ahead of these parts in the recorded benchmark, which suggests its measured performance in this specific test is modest. The MI308X, however, has no comparable benchmark entry, so no direct performance comparison exists in the database.

The verdict is straightforward from the data. Choose the MI308X for compute workloads requiring massive memory and FP16 throughput. Choose the RTX 5070 SUPER for graphics rendering, display output, and DirectX 12 workloads. The MI308X has no pixel rate, no graphics APIs, and no display outputs, so it cannot perform the RTX 5070 SUPER's primary functions. The RTX 5070 SUPER has 18 GB of memory and 32.15 TFLOPS FP32, far below the MI308X's capacities, so it cannot perform the AMD part's primary functions.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two products. The MI308X has no benchmarks listed at all, and the RTX 5070 SUPER has exactly one: 3DMark Steel Nomad DX12 with a score of 2690. The MI308X has an average benchmark score of 0 and a percentile rank of 50 among all GPUs, while the RTX 5070 SUPER has an average score of 2690 and an 18th percentile rank.

Because the MI308X has no graphics API support, it would not be expected to run a DirectX 12 benchmark at all. The RTX 5070 SUPER's 2690 score sits very close to its nearest rivals. The Quadro K1100M scores 2664, a 1% deficit. The GT 1030 scores 2662, 1.1% behind. The Arc Pro B50 scores 2660, also 1.1% behind. The GT 440 scores 2645, 1.7% behind. These deltas are small, meaning the RTX 5070 SUPER's advantage in this single test is narrow. The 18th percentile ranking confirms that most GPUs in the database score higher in this test.

The compute comparison is one-sided on paper. The MI308X has 19456 shading units versus 6400, 1216 TMUs versus 200, and 80 ROPs only on the NVIDIA side. The MI308X texture rate is 2,553.6 GTexel/s, about 5.1x the RTX 5070 SUPER's 502.4 GTexel/s. FP32 output is 81.72 TFLOPS versus 32.15 TFLOPS, a 2.5x difference. FP16 output is 653.7 TFLOPS versus 32.15 TFLOPS, a 20.3x difference. Memory bandwidth is 10.3 TB/s versus 672.0 GB/s, a 15.3x difference. These are the largest gaps in the recorded data. The RTX 5070 SUPER leads in pixel rate, 201.0 GPixel/s versus 0, and in clock speeds.
