AMD Instinct MI350X vs NVIDIA GeForce RTX 4070 Ti Comparison

# AMD Instinct MI350X vs NVIDIA GeForce RTX 4070 Ti

The AMD Instinct MI350X and NVIDIA GeForce RTX 4070 Ti occupy opposite ends of the GPU spectrum: the MI350X is a data-center compute accelerator built on CDNA 4.0 with no display outputs, while the RTX 4070 Ti is a consumer gaming and workstation card from the GeForce 40-series. The recorded data shows no head-to-head benchmark results between the two, and the MI350X carries no benchmark scores in the database. Consequently, this comparison relies on architectural specifications, memory capabilities, and the RTX 4070 Ti's measured performance relative to its nearest rivals.

Where Each One Wins

The RTX 4070 Ti wins in every measured benchmark category because it is the only one of the two with recorded benchmark data. Its average benchmark score of 44,795 places it at the 84th percentile among all GPUs in the database. The MI350X has an average benchmark score of 0 and sits at the 50th percentile, reflecting the absence of any recorded benchmark results rather than actual performance equivalence.

For compute workloads, the MI350X holds the clear specification advantage. It delivers 72.09 TFLOPS for both FP32 and FP16, compared to the RTX 4070 Ti's 40.09 TFLOPS for both precision formats. The MI350X also provides 288 GB of HBM3e memory with 8.19 TB/s bandwidth, dwarfing the RTX 4070 Ti's 12 GB of GDDR6X at 504.2 GB/s. These numbers indicate the MI350X is designed for large-scale AI training, inference, and scientific computing where memory capacity and bandwidth dominate.

The RTX 4070 Ti wins in rendering and graphics-oriented tasks. It has 80 ROPs and a pixel rate of 208.8 GPixel/s, whereas the MI350X has 0 ROPs and a pixel rate of 0 MPixel/s. The RTX 4070 Ti also includes 60 ray-tracing cores and 240 tensor cores, features entirely absent from the MI350X specification. Display outputs on the RTX 4070 Ti (1x HDMI 2.1, 3x DisplayPort 1.4a) make it usable for direct monitor connection, while the MI350X has no outputs.

The MI350X wins on texture throughput, posting 2,252.8 GTexel/s versus 626.4 GTexel/s for the RTX 4070 Ti, and it has 1,024 TMUs against 240. Thermal design differences also favor the MI350X for raw throughput: its 1000 W TDP pairs with a 1400 W suggested PSU, while the RTX 4070 Ti uses 285 W with a 600 W suggested PSU.

Architecture Differences

The MI350X uses the CDNA 4.0 architecture built on a 3 nm process at TSMC, while the RTX 4070 Ti uses Ada Lovelace on a 5 nm process, also at TSMC. The MI350X chip is labeled "MI350 256CU" and belongs to the Instinct (MIx) generation. The RTX 4070 Ti uses the AD104 chip from the GeForce 40 generation.

Transistor counts differ substantially: the MI350X integrates 185,000 million transistors on a 2380 mm² die, giving a transistor density of 77.7M per mm². The RTX 4070 Ti has 35,800 million transistors on a 294 mm² die, with a higher density of 121.8M per mm². The MI350X's enormous die size reflects its 16,384 shading units and 1,024 TMUs, compared to 7,680 shading units and 240 TMUs on the RTX 4070 Ti.

The MI350X uses HBM3e memory across an 8192-bit bus, while the RTX 4070 Ti uses GDDR6X across a 192-bit bus. Clock behavior also differs: the MI350X has a base clock of 1000 MHz and boost clock of 2200 MHz with memory at 2000 MHz (8 Gbps effective). The RTX 4070 Ti runs a base clock of 2310 MHz and boost clock of 2610 MHz with memory at 1313 MHz (21 Gbps effective).

API support separates the two completely. The MI350X reports N/A for DirectX, OpenGL, and Vulkan, indicating no graphics API support. The RTX 4070 Ti supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Physical formats diverge as well: the MI350X is an OAM Module measuring 102 mm by 165 mm with no power connectors, while the RTX 4070 Ti is a dual-slot card at 285 mm by 112 mm by 42 mm with a single 16-pin power connector. The MI350X uses PCIe 5.0 x16, and the RTX 4070 Ti uses PCIe 4.0 x16.

Head-to-Head Benchmarks

No direct head-to-head benchmark results exist in the database for these two products. The wins counter shows 0 for both the MI350X and the RTX 4070 Ti in pairwise testing. The MI350X has no benchmark entries at all, while the RTX 4070 Ti has ten recorded tests.

The RTX 4070 Ti's benchmark results include a 3DMark Steel Nomad DX12 score of 5,024, a Geekbench OpenCL score of 176,953, and a Geekbench Vulkan score of 213,808. In Passmark tests, it scores 187 in DirectX 10, 288 in DirectX 11, 116 in DirectX 12, 352 in DirectX 9, 1,200 in G2D, 31,624 in G3D, and 18,396 in GPU Compute.

The nearest rivals for the RTX 4070 Ti provide context for its standing. The NVIDIA GeForce RTX 5090 Mobile has an average score of 45,152, which is 0.8% higher than the RTX 4070 Ti's 44,795. The AMD Radeon Pro 5500 XT scores 45,384, 1.3% higher. The NVIDIA RTX A6000 scores 44,075, which is 1.6% lower. The Intel Arc A730M scores 45,592, 1.7% higher. These deltas indicate the RTX 4070 Ti sits tightly clustered with these four products, within roughly 2% either direction.

For the MI350X, the absence of benchmark data means no percentile rank can be meaningfully interpreted. Its 50th percentile value likely reflects the default position for unmeasured products rather than a performance estimate. The database records no rival comparisons for it.
