AMD Instinct MI350X vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

Where Each One Wins

The AMD Instinct MI350X and NVIDIA GeForce RTX 5070 Ti Mobile occupy opposite ends of the hardware spectrum, and the recorded data reflects that split clearly. The MI350X is a compute-oriented accelerator with no display outputs, no graphics API support, and a 1000 W thermal design power. The RTX 5070 Ti Mobile is a portable graphics processor with full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, drawing only 60 W. Their benchmark portfolios do not overlap: the database lists zero benchmark entries for the MI350X, while the RTX 5070 Ti Mobile has nine recorded scores across Geekbench and Passmark tests.

The MI350X wins in raw compute capacity, memory bandwidth, and sheer silicon scale. It delivers 72.09 TFLOPS of FP32 throughput, which is 4.2 times the RTX 5070 Ti Mobile's 17.04 TFLOPS. Its memory system, 288 GB of HBM3e on an 8192-bit bus, provides 8.19 TB/s of bandwidth, dwarfing the 672.0 GB/s available to the RTX 5070 Ti Mobile. The MI350X also has 16,384 shading units versus 5,888, and 1,024 texture mapping units versus 184. These numbers indicate a device built for massive parallel workloads, not for rendering frames to a screen.

The RTX 5070 Ti Mobile wins in every category that requires a functional graphics pipeline. It has 80 ROPs, a pixel rate of 115.8 GPixel/s, and 46 ray tracing cores, while the MI350X has zero ROPs, a pixel rate of 0 MPixel/s, and no ray tracing cores. The RTX 5070 Ti Mobile also carries 184 tensor cores, which the MI350X lacks entirely. Its Passmark scores, such as 24,004 in G3D and 10101 in GPU Compute, indicate an operational graphics processor. The MI350X has no benchmark scores at all, so the database cannot confirm any real-world performance for it.

The use-case split is therefore straightforward. The MI350X is for compute tasks that demand enormous memory capacity and bandwidth, such as large-scale scientific simulation or machine learning training. The RTX 5070 Ti Mobile is for interactive graphics, ray tracing, and general-purpose GPU compute in a portable form factor. The MI350X cannot output video, so it cannot serve as a display adapter. The RTX 5070 Ti Mobile is specified as "Portable Device Dependent" for display outputs, meaning it relies on laptop hardware to drive panels.

Head-to-Head Benchmarks

Direct head-to-head benchmark results are absent from the database, as the headToHeadBenchmarks array is empty and the MI350X has no recorded benchmark scores. However, the available data for the RTX 5070 Ti Mobile allows for contextual analysis against its nearest rivals, and the MI350X's specifications can be compared directly to the RTX 5070 Ti Mobile's measured outputs.

The RTX 5070 Ti Mobile's Passmark G3D score of 24,004 places it in the 80th percentile of all GPUs in the database. Its Passmark GPU Compute score of 10,101 indicates a functional compute workload capability, though it trails its own G3D score significantly. In Geekbench, it scores 143,870 in OpenCL and 139,213 in Vulkan, showing strong API-level performance for a mobile part. The nearest rival data shows the RTX 5070 Ti Mobile is essentially tied with the NVIDIA Quadro GV100 (35,520, delta -0.2%) and the AMD Radeon Pro Duo (35,860, delta -1.2%), while sitting slightly above the NVIDIA A2 (34,690, delta 2.1%) and below the NVIDIA T1000 (36,289, delta -2.4%). These deltas are all within a narrow band, indicating that the RTX 5070 Ti Mobile performs at parity with several established workstation and professional cards despite its mobile positioning.

The MI350X cannot be placed in this comparison because it has no benchmark scores and no nearest rivals listed. Its specification sheet, however, suggests a compute device of an entirely different class. The FP32 throughput of 72.09 TFLOPS is 4.2 times that of the RTX 5070 Ti Mobile. The texture rate of 2,252.8 GTexel/s is 8.5 times the RTX 5070 Ti Mobile's 266.2 GTexel/s. The memory bandwidth of 8.19 TB/s is 12.2 times the RTX 5070 Ti Mobile's 672.0 GB/s. These are not incremental advantages; they represent orders of magnitude in specific metrics. The MI350X also has a much larger die, 2380 mm² versus 263 mm², and more transistors, 185,000 million versus 31,100 million.

The RTX 5070 Ti Mobile counters with the only measured graphics capabilities in this pairing. Its pixel rate of 115.8 GPixel/s is real, while the MI350X is listed at 0 MPixel/s. Its 80 ROPs enable rasterization, and its 46 ray tracing cores enable hardware-accelerated ray tracing. The MI350X has none of these. The RTX 5070 Ti Mobile also runs at a higher boost clock relative to its base, 1447 MHz versus 847 MHz, while the MI350X boosts from 1000 MHz to 2200 MHz. Clock speeds alone do not tell the full story, but the MI350X's higher clocks combined with its massive shader count explain its compute advantage.

Specification Differences

The two GPUs differ in nearly every measurable specification. The MI350X uses a 3 nm process node from TSMC, while the RTX 5070 Ti Mobile uses a 5 nm node, also from TSMC. The MI350X has 185,000 million transistors on a 2380 mm² die, yielding a transistor density of 77.7 million per mm². The RTX 5070 Ti Mobile has 31,100 million transistors on a 263 mm² die, yielding 118.3 million per mm². The RTX 5070 Ti Mobile is denser, but the MI350X is far larger overall.

Memory configurations diverge completely. The MI350X uses 288 GB of HBM3e with an 8192-bit bus and 8.19 TB/s bandwidth. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 with a 192-bit bus and 672.0 GB/s bandwidth. Memory clock rates are listed as 2000 MHz (8 Gbps effective) for the MI350X and 1750 MHz (28 Gbps effective) for the RTX 5070 Ti Mobile.

Compute resources differ by a factor of roughly three to five. The MI350X has 16,384 shading units, 1,024 TMUs, and 0 ROPs. The RTX 5070 Ti Mobile has 5,888 shading units, 184 TMUs, and 80 ROPs. The MI350X has no ray tracing or tensor cores; the RTX 5070 Ti Mobile has 46 and 184, respectively. FP32 and FP16 performance are both 72.09 TFLOPS for the MI350X and 17.04 TFLOPS for the RTX 5070 Ti Mobile, with both listed at a 1:1 ratio.

Physical and power characteristics are equally divergent. The MI350X is an OAM Module with dimensions of 102 mm in length and 165 mm in width, while the RTX 5070 Ti Mobile is an IGP with no listed dimensions. The MI350X has a TDP of 1000 W and a suggested PSU of 1400 W. The RTX 5070 Ti Mobile has a TDP of 60 W and no suggested PSU. Neither uses external power connectors. The MI350X has no display outputs; the RTX 5070 Ti Mobile has outputs described as "Portable Device Dependent." Both use PCIe 5.0 x16 interfaces.

Release dates differ by about three and a half months. The RTX 5070 Ti Mobile launched on 2025-02-28, and the MI350X launched on 2025-06-11. The production status of the MI350X is not recorded, while the RTX 5070 Ti Mobile is marked as "Active."

Architecture Differences

The MI350X uses the CDNA 4.0 architecture, designed for compute acceleration in data centers and scientific workloads. The RTX 5070 Ti Mobile uses the Blackwell 2.0 architecture, designed for consumer and professional graphics in laptops. The MI350X is part of AMD's Instinct (MIx) generation, succeeding the Radeon Instinct line. The RTX 5070 Ti Mobile is part of NVIDIA's GeForce 50 Mobile generation, succeeding the GeForce 40 Mobile line.

The chip design reflects these different mandates. The MI350X uses an "MI350 256CU" chip, indicating 256 compute units. The RTX 5070 Ti Mobile uses the GB205 chip. The MI350X's architecture provides no graphics API support, no display engine, and no rasterization hardware. Its 0 ROPs and 0 MPixel/s pixel rate confirm that it is not intended to produce images. The CDNA architecture instead focuses on maximizing FP32 and FP16 throughput, memory bandwidth, and texture rate, all of which are present in large quantities.

The Blackwell 2.0 architecture in the RTX 5070 Ti Mobile includes a full graphics pipeline: 80 ROPs for pixel output, 46 ray tracing cores for RT workloads, and 184 tensor cores for AI acceleration. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it compatible with modern game and rendering APIs. The architecture also enables a high pixel rate of 115.8 GPixel/s, which is essential for driving laptop displays.

The manufacturing process and transistor budgets also differ. The MI350X uses 3 nm lithography with 185,000 million transistors, while the RTX 5070 Ti Mobile uses 5 nm with 31,100 million. The MI350X's die is 9 times larger in area, but its transistor density is lower (77.7M per mm² versus 118.3M per mm²). This suggests the MI350X allocates more die area to memory controllers, HBM3e stacking, and compute arrays, while the RTX 5070 Ti Mobile's smaller, denser die integrates fixed-function graphics hardware more efficiently.

The Verdict

The data supports a clear division of roles. The AMD Instinct MI350X is a compute accelerator for workloads that need massive memory capacity and bandwidth. Its 288 GB of HBM3e and 8.19 TB/s bandwidth are unmatched by the RTX 5070 Ti Mobile, and its 72.09 TFLOPS of FP32 throughput is 4.2 times higher. The MI350X has no display outputs, no graphics API support, and no rasterization hardware, so it cannot function as a graphics card in any traditional sense. Its 1000 W TDP and 1400 W suggested PSU indicate a fixed installation in a server or compute chassis.

The NVIDIA GeForce RTX 5070 Ti Mobile is a graphics processor for portable systems. It delivers 115.8 GPixel/s pixel throughput, 80 ROPs, 46 ray tracing cores, and 184 tensor cores, all within a 60 W power envelope. Its benchmark scores, including a Passmark G3D score of 24,004 and an average benchmark score of 35,435, place it in the 80th percentile of all GPUs. It sits within 2.4% of its nearest rivals, the NVIDIA Quadro GV100, AMD Radeon Pro Duo, NVIDIA A2, and NVIDIA T1000, indicating competitive performance in its class.

For users with compute-heavy tasks that fit within a server environment, the MI350X is the only choice between these two, because the RTX 5070 Ti Mobile cannot match its memory capacity or FP32 throughput. For users who need graphics output, ray tracing, or a GPU that can operate in a laptop, the RTX 5070 Ti Mobile is the only viable option, as the MI350X cannot display images at all. The recorded data does not provide any scenario where these two devices compete directly; they serve different purposes with almost no overlap in features or capabilities.
