AMD Instinct MI325X vs NVIDIA GeForce RTX 5070 SUPER Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark runs between the AMD Instinct MI325X and the NVIDIA GeForce RTX 5070 SUPER. The MI325X has no recorded benchmark scores, while the RTX 5070 SUPER has a single entry in the 3DMark Steel Nomad DX12 test. That score is 2690, placing the card at the 18th percentile of all GPUs tracked. The nearest recorded rivals for the RTX 5070 SUPER 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). This places the RTX 5070 SUPER within a narrow competitive band, separated from its nearest rivals by no more than 1.7%.

Because the MI325X carries no benchmark entries, the recorded data offers no comparative frame for its compute performance. The MI325X lists an average benchmark score of zero, which reflects the absence of submitted results rather than a measured performance level. Its percentile rank of 50 is a positional placeholder, not a derived statistic from test runs. Any attempt to directly compare the two cards through the database's benchmark suite produces no meaningful delta values, as the head-to-head benchmark array is empty and neither card records a win in the winsA or winsB fields.

The RTX 5070 SUPER's single benchmark result, 2690, is the only concrete performance figure available between the two products. The MI325X's compute capacity is documented through its rated specifications instead: 81.72 TFLOPS FP32 and 81.72 TFLOPS FP16 (1:1), with a texture rate of 2,553.6 GTexel/s. The RTX 5070 SUPER delivers 32.15 TFLOPS FP32 and 32.15 TFLOPS FP16 (1:1), with a texture rate of 502.4 GTexel/s. These figures indicate a large gap in raw computational throughput, with the MI325X rated at roughly 2.5 times the FP32 throughput of the RTX 5070 SUPER, though the absence of shared benchmark data prevents a direct measured confirmation.

The Verdict

The recorded data splits the two cards into entirely different usage domains. The AMD Instinct MI325X is a compute-oriented accelerator with no display outputs, no graphics API support (DirectX, OpenGL, and Vulkan are all listed as N/A), and a 1000 W TDP. It is an OAM module, not a consumer graphics card. The NVIDIA GeForce RTX 5070 SUPER is a dual-slot consumer graphics card with 1x HDMI 2.1b and 3x DisplayPort 2.1b outputs, full API support (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4), and a 275 W TDP. The data positions the RTX 5070 SUPER for standard graphics workloads, rendering, and display output, while the MI325X is built for high-throughput compute without any display capability.

For users selecting between these two based strictly on benchmark evidence, the RTX 5070 SUPER is the only one with a measured score: 2690 in 3DMark Steel Nomad DX12, which is 1% ahead of the Quadro K1100M, 1.1% ahead of the GT 1030 and Arc Pro B50, and 1.7% ahead of the GT 440. The MI325X has no measured results, so no performance verdict can be drawn from the database's benchmark suite. The MI325X's rated compute specifications are substantially higher, but those are not validated by any recorded test.

The data indicates the RTX 5070 SUPER is the appropriate choice for any workload requiring graphics output, API compatibility, or standard desktop operation. The MI325X is the appropriate choice for server or accelerator environments where raw compute throughput and massive memory capacity are the priorities, given its 256 GB HBM3e memory, 8192-bit bus, and 6.14 TB/s bandwidth. The two products do not compete in the same segment; the RTX 5070 SUPER targets rasterization and real-time rendering, while the MI325X targets data-center scale compute.

Architecture Differences

The MI325X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, manufactured on a 5 nm process at TSMC. The RTX 5070 SUPER uses the GB205 chip built on Blackwell 2.0 architecture, also manufactured on a 5 nm process at TSMC. Both cards share the same process node and foundry, but their architectural goals diverge sharply.

The MI325X integrates 153,000 million transistors across a 1017 mm² die, yielding a transistor density of 150.4 million transistors per square millimeter. The RTX 5070 SUPER integrates 31,100 million transistors on a 263 mm² die, with a transistor density of 118.3 million per square millimeter.

Where Each One Wins

The AMD Instinct MI325X wins decisively in raw compute throughput. Its FP32 rating of 81.72 TFLOPS and FP16 rating of 81.72 TFLOPS (1:1) are both more than double the RTX 5070 SUPER's 32.15 TFLOPS in each mode. Its texture rate of 2,553.6 GTexel/s is roughly 5.1 times the RTX 5070 SUPER's 502.4 GTexel/s. The MI325X's memory subsystem is in a different class entirely: 256 GB capacity, 6.14 TB/s bandwidth, and an 8192-bit bus, compared to 18 GB, 672.0 GB/s, and a 192-bit bus. For large-scale compute workloads, model training, or data-center inference, the MI325X's specifications dominate.

The NVIDIA GeForce RTX 5070 SUPER wins in every area related to conventional graphics and display. It offers full API support, including DirectX 12 Ultimate and Vulkan 1.4, while the MI325X has none. It has 80 ROPs and a pixel rate of 201.0 GPixel/s, while the MI325X has 0 ROPs and a pixel rate of 0 MPixel/s. It provides display outputs, which the MI325X lacks entirely. Its clock speeds are higher (2325 MHz base, 2512 MHz boost versus 1000 MHz and 2100 MHz), and its power draw is far lower at 275 W versus 1000 W. The RTX 5070 SUPER also has a measured benchmark score of 2690 in 3DMark Steel Nomad DX12, placing it at the 18th percentile, while the MI325X has no recorded benchmark results.

The RTX 5070 SUPER's nearest rivals in the database, all within 1.7%, are low-end or older GPUs, indicating its measured performance is modest relative to the broader GPU landscape. That said, it is the only card between the two with any benchmark data. For any task requiring a monitor, a graphics API, or a standard desktop or workstation environment, the RTX 5070 SUPER is the only viable option. For any task requiring maximum memory capacity, memory bandwidth, or raw FP32 throughput in a server context, the MI325X holds the advantage based on its rated specifications. The data does not support a direct performance comparison, as no shared benchmark results exist.
