AMD Instinct MI350X vs NVIDIA GeForce RTX 5070 Mobile Comparison

The Verdict

The database contains no shared benchmark results for the AMD Instinct MI350X and the NVIDIA GeForce RTX 5070 Mobile. The MI350X has no recorded benchmark scores, an average score of 0, and a percentile rank of 50 among all GPUs. The RTX 5070 Mobile, by contrast, has nine recorded benchmark results, an average score of 29,928, and a percentile rank of 75.

The MI350X is a 1000 W OAM module with 288 GB of HBM3e memory, 16,384 shading units, and a 2,252.8 GTexel/s texture rate. It is designed for compute acceleration in servers, with no display outputs and no graphics API support. The RTX 5070 Mobile is a 50 W integrated graphics processor for laptops, with 4,608 shading units, 36 ray tracing cores, 144 tensor cores, and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support.

The recorded data indicates that the RTX 5070 Mobile is the only one of the two with measurable graphics performance in the database. Its average score of 29,928 places it within 0.1% (below) of the NVIDIA GeForce RTX 3070 Ti, within 0.5% (above) of the NVIDIA GeForce RTX 2080 Ti, within 0.6% (below) of the AMD Radeon RX 6800, and within 1.7% (below) of the AMD Radeon RX 6700. The MI350X cannot be compared on any benchmark metric because no such data exists.

For any task requiring rendering, ray tracing, or general graphics acceleration, the RTX 5070 Mobile is the only option with empirical support. For tasks requiring massive memory capacity and compute throughput, the MI350X presents a hardware configuration aimed at that role, but its performance relative to the RTX 5070 Mobile is not quantified in the database.

Architecture Differences

The two processors use fundamentally different architectures. The MI350X is built on CDNA 4.0, AMD's compute-focused architecture, and uses the MI350 256CU chip. The RTX 5070 Mobile uses Blackwell 2.0, NVIDIA's graphics and compute architecture, with the GB206 chip. This architectural divergence explains their different feature sets and intended workloads.

The MI350X is fabricated on a 3 nm process at TSMC, with 185,000 million transistors on a 2380 mm² die, resulting in a transistor density of 77.7 million per square millimeter. The RTX 5070 Mobile uses a 5 nm process at the same foundry, with 21,900 million transistors on a 181 mm² die, giving a transistor density of 121.0 million per square millimeter. The MI350X has a much larger physical die and transistor budget, while the RTX 5070 Mobile achieves higher density per area.

Clock behavior also differs sharply. The MI350X has a base clock of 1000 MHz and a boost clock of 2200 MHz. The RTX 5070 Mobile has a base clock of 907 MHz and a boost clock of 1425 MHz. The MI350X runs at higher frequencies, though its power envelope is vastly larger.

The MI350X has no ray tracing cores and no tensor cores listed, while the RTX 5070 Mobile includes 36 ray tracing cores and 144 tensor cores. The MI350X also lists zero ROPs and a pixel rate of 0 MPixel/s, confirming it lacks traditional rasterization output units. The RTX 5070 Mobile has 48 ROPs and a pixel rate of 68.40 GPixel/s.

Memory architecture is a major differentiator. The MI350X uses 288 GB of HBM3e on a 8192 bit bus, delivering 8.19 TB/s of bandwidth. The RTX 5070 Mobile uses 8 GB of GDDR7 on a 128 bit bus, delivering 384.0 GB/s. The MI350X has 23 times the capacity and over 21 times the bandwidth, though the memory clock is 2000 MHz (8 Gbps effective) versus 1500 MHz (24 Gbps effective) for the RTX 5070 Mobile.

The MI350X supports no graphics APIs: DirectX, OpenGL, and Vulkan are all listed as N/A. The RTX 5070 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This reflects the MI350X's role as a compute accelerator rather than a graphics card.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two products. The winsA and winsB fields are both zero. Consequently, there is no direct measurement showing one outperforming the other on any specific test.

For the RTX 5070 Mobile, the recorded benchmark results provide a full picture of its performance. In Geekbench OpenCL, it scores 122,238. In Geekbench Vulkan, it scores 116,960. In PassMark tests, it scores 129 in DirectX 10, 192 in DirectX 11, 93 in DirectX 12, 214 in DirectX 9, 896 in G2D, 20,355 in G3D, and 8,279 in GPU Compute. Its average benchmark score is 29,928.

These scores place the RTX 5070 Mobile at the 75th percentile among all GPUs in the database. Its nearest rivals in average score are the NVIDIA GeForce RTX 3070 Ti at 29,945 (0.1% ahead), the NVIDIA GeForce RTX 2080 Ti at 29,783 (0.5% behind), the AMD Radeon RX 6800 at 30,095 (0.6% ahead), and the AMD Radeon RX 6700 at 30,433 (1.7% ahead). The RTX 5070 Mobile sits within a narrow band of these desktop-class GPUs, despite being a mobile part.

The MI350X has no benchmark scores in the database. Its average benchmark score is 0, and its percentile rank is 50, which is the default value for unmeasured parts. The data shows no way to establish its performance relative to the RTX 5070 Mobile or any other GPU.

The texture rate provides a theoretical comparison. The MI350X has a texture rate of 2,252.8 GTexel/s, while the RTX 5070 Mobile has a texture rate of 205.2 GTexel/s. The MI350X's FP32 throughput is 72.09 TFLOPS, and its FP16 throughput is also 72.09 TFLOPS (1:1). The RTX 5070 Mobile's FP32 throughput is 13.13 TFLOPS, and its FP16 throughput is 13.13 TFLOPS (1:1). These theoretical numbers indicate a large compute advantage for the MI350X, but they are not derived from actual benchmark runs.
