AMD Instinct MI350X vs NVIDIA GeForce RTX 5070 Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Instinct MI350X and the NVIDIA GeForce RTX 5070. The MI350X has an empty benchmark record with an average score of 0 and a percentile ranking of 50 among all GPUs, while the RTX 5070 shows a substantial set of recorded results.

The NVIDIA GeForce RTX 5070 delivers an average benchmark score of 40,377 across all recorded tests. Its percentile placement sits at 82, meaning it outperforms the vast majority of GPUs in the database. The MI350X, lacking any benchmark entries, cannot be positioned against it through measured performance data.

For the RTX 5070, the strongest individual results come from compute-oriented workloads. The Geekbench OpenCL score reaches 172,660, while the Geekbench Vulkan result climbs slightly higher to 178,923. These two results indicate strong general-purpose compute throughput.

The Passmark suite reveals a different pattern. The G3D score of 29,137 far exceeds the DirectX 10 score of 180, the DirectX 11 score of 277, and the DirectX 12 score of 108. The DirectX 9 result of 320 also remains modest. Passmark GPU compute lands at 15,787, while the G2D score reaches only 1,305.

The 3DMark Steel Nomad DX12 test produces a score of 5,077 for the RTX 5070. This result, combined with the Passmark G3D figure, suggests the card handles modern graphics workloads far better than legacy DirectX paths.

For the MI350X, the hardware specifications indicate a fundamentally different purpose. The card uses 16,384 shading units, 1,024 texture mapping units, and zero ROPs. Its pixel rate is recorded as 0 MPixel/s, confirming it has no traditional rasterization output stage. The texture rate reaches 2,252.8 GTexel/s, which is substantially higher than the RTX 5070's 482.3 GTexel/s.

The MI350X achieves 72.09 TFLOPS in both FP32 and FP16 with a 1:1 ratio. The RTX 5070 delivers 30.87 TFLOPS in both formats, also at 1:1. The MI350X therefore provides roughly 2.3 times the floating-point throughput of the RTX 5070, though this comparison comes from specification sheets rather than measured benchmark data.

Where Each One Wins

The RTX 5070 wins in every measurable benchmark category because it has recorded results and the MI350X has none. The average benchmark score of 40,377 places it 0.1% ahead of the AMD Radeon Pro 580, 0.8% ahead of the AMD Radeon Pro WX 7100, and 2% ahead of the NVIDIA RTX A500 Mobile. It trails the AMD Radeon Pro 5300 by 1.2%.

The MI350X wins on raw specification strength. Its FP32 compute of 72.09 TFLOPS more than doubles the RTX 5070's 30.87 TFLOPS. Memory capacity differs dramatically: the MI350X carries 288 GB of HBM3e across an 8192-bit bus, yielding 8.19 TB/s of bandwidth. The RTX 5070 uses 12 GB of GDDR7 on a 192-bit bus with 672.0 GB/s. The MI350X offers roughly 12 times the memory bandwidth.

For rasterization workloads, the RTX 5070 holds clear advantages. Its 80 ROPs and 201.0 GPixel/s pixel rate enable traditional display output, which the MI350X lacks entirely. The RTX 5070 also includes 48 ray tracing cores and 192 tensor cores, features absent from the MI350X specification sheet. The MI350X supports no DirectX, OpenGL, or Vulkan APIs, while the RTX 5070 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The RTX 5070 includes display outputs with one HDMI 2.1b and three DisplayPort 2.1b connectors. The MI350X records no display outputs. The RTX 5070 is an active production product with a dual-slot form factor, while the MI350X uses an OAM module format.

Architecture Differences

The MI350X uses the MI350 256CU chip built on CDNA 4.0 architecture, fabricated on a 3 nm process at TSMC. The RTX 5070 uses the GB205 chip with Blackwell 2.0 architecture, also fabricated at TSMC but on a 5 nm process.

Transistor counts reveal opposite design strategies. The MI350X packs 185,000 million transistors across a 2380 mm² die, yielding a density of 77.7 million transistors per square millimeter. The RTX 5070 contains 31,100 million transistors on a 263 mm² die with a density of 118.3 million per square millimeter. The MI350X prioritizes sheer scale, while the RTX 5070 achieves higher density on a much smaller package.

Clock behavior differs substantially. The MI350X runs at a 1000 MHz base and 2200 MHz boost. The RTX 5070 operates at 2325 MHz base and 2512 MHz boost, giving it a higher clock ceiling despite the larger process node. Memory clocks also diverge: the MI350X memory runs at 2000 MHz with 8 Gbps effective speed, while the RTX 5070 memory runs at 1750 MHz with 28 Gbps effective speed.

The MI350X uses 288 GB of HBM3e memory with an 8192-bit bus. The RTX 5070 uses 12 GB of GDDR7 with a 192-bit bus. The memory type difference explains the bandwidth gap: 8.19 TB/s versus 672.0 GB/s.

Power requirements reflect the architectural split. The MI350X has a TDP of 1000 W and a suggested PSU of 1400 W, with no power connectors on the OAM module itself. The RTX 5070 draws 250 W, uses a single 16-pin connector, and suggests a 600 W PSU. The MI350X consumes four times the power budget of the RTX 5070.

Physical dimensions also differ. The MI350X measures 102 mm long and 165 mm wide. The RTX 5070 measures 245 mm long, 115 mm high, and 40 mm wide. The RTX 5070 occupies a standard dual-slot graphics card footprint, while the MI350X uses a compact OAM module form factor.

Feature sets diverge completely. The MI350X has no ray tracing cores, no tensor cores, and no graphics API support. The RTX 5070 includes 48 ray tracing cores, 192 tensor cores, and full support for modern graphics APIs. The MI350X targets compute acceleration, while the RTX 5070 serves as a complete graphics solution.

The Verdict

The data indicates two products designed for entirely different workloads. The AMD Instinct MI350X exists for high-throughput compute applications. Its 72.09 TFLOPS FP32 performance, 288 GB memory capacity, and 8.19 TB/s bandwidth make it a specialized accelerator. The absence of ROPs, display outputs, and graphics API support confirms this positioning.

The NVIDIA GeForce RTX 5070 functions as a conventional graphics card. Its 30.87 TFLOPS FP32 performance, 12 GB memory, and 672.0 GB/s bandwidth serve gaming and workstation graphics workloads. The inclusion of 80 ROPs, 48 ray tracing cores, 192 tensor cores, and display outputs makes it a complete visual computing solution.

For users requiring graphics output, gaming performance, or ray tracing, the RTX 5070 is the only viable option between these two. Its benchmark percentile of 82 and average score of 40,377 demonstrate solid performance among all GPUs. Its nearest rivals sit within 2% of its average score, indicating a competitive field.

For users requiring massive memory capacity, extreme bandwidth, or maximum compute throughput in a server environment, the MI350X offers specifications the RTX 5070 cannot match. The 288 GB memory capacity, 8192-bit bus, and 2,252.8 GTexel/s texture rate place it in a different performance class entirely.

The RTX 5070 launched on March 3, 2025, with a launch MSRP of 549 USD. The MI350X released on June 11, 2025, with no recorded launch MSRP. The RTX 5070 lists as an active production product, succeeding the GeForce 40 series and preceding the GeForce 60 series. The MI350X succeeds the Radeon Instinct line within the Instinct (MIx) generation.

Neither product can substitute for the other. The RTX 5070 cannot handle the memory and bandwidth demands of large-scale compute workloads. The MI350X cannot render graphics or drive displays. The selection depends entirely on workload requirements.
