AMD Instinct MI350P vs NVIDIA GeForce RTX 4070 Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no overlapping benchmark results between the AMD Instinct MI350P and the NVIDIA GeForce RTX 4070 Mobile. The MI350P has no benchmark entries in the database, while the RTX 4070 Mobile has a full suite of nine recorded tests. This absence of direct comparison data means the head-to-head analysis must rely on architectural specifications and the RTX 4070 Mobile's performance against its own nearest rivals.

The RTX 4070 Mobile posts an average benchmark score of 27435 across its nine tests. Its percentile rank of 73 places it above the majority of all GPUs tracked in the database. The nearest rival data shows the RTX 4070 Mobile essentially tied with the AMD Radeon RX 6700 XT, which scores 27425, a delta of 0 percent. Against the NVIDIA GeForce RTX 3090, the mobile part trails by a mere 0.5 percent, with the desktop flagship scoring 27565. The NVIDIA RTX PRO 4000 Blackwell trails the mobile part by 1.1 percent, scoring 27135. The AMD Radeon Pro Vega 20 leads the mobile part by 1.5 percent with a score of 27839.

Individual benchmark scores for the RTX 4070 Mobile show its strongest result in Geekbench OpenCL at 109197, with Geekbench Vulkan close behind at 108367. Passmark G3D delivers 19587, while Passmark GPU Compute reaches 8399. The legacy DirectX tests show lower figures: DirectX 9 scores 223, DirectX 11 scores 179, DirectX 10 scores 116, and DirectX 12 scores 85. The G2D test records 763. These results indicate a capable mobile graphics solution, though the DirectX 12 score of 85 appears disproportionately low relative to the other metrics.

The MI350P, by contrast, has no recorded benchmark scores and an average benchmark score of zero. Its percentile rank of 50 places it at the midpoint of all GPUs, but this rank derives from no actual performance measurements. The data cannot substantiate any performance comparison between the two parts. What the data does show is a massive disparity in raw compute specifications, which will be examined in the architecture section.

Where Each One Wins

The RTX 4070 Mobile wins in any scenario where measured performance data exists. Its nine recorded benchmarks cover OpenCL, Vulkan, and a range of DirectX versions, plus 2D and compute workloads. The MI350P has no measured wins in any category, as the database contains no benchmark results for it.

The RTX 4070 Mobile's Geekbench OpenCL score of 109197 and Vulkan score of 108367 indicate strong general-purpose compute and graphics API performance. The Passmark G3D score of 19587 supports its positioning as a mobile gaming and workstation part. The compute score of 8399 shows additional capacity for non-graphics workloads.

The MI350P's specification sheet suggests its intended use case: 144 GB of HBM3e memory, an 8192-bit memory bus, and 8.19 TB/s of bandwidth. These figures point to a data center accelerator designed for massive memory-bound workloads rather than client graphics. The absence of display outputs and API support for DirectX, OpenGL, and Vulkan confirms this part has no consumer graphics function.

The RTX 4070 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it a fully featured client GPU. The MI350P lists N/A for all three APIs, meaning it cannot run standard graphics applications. The data shows the RTX 4070 Mobile wins in every measurable software compatibility category.

Architecture Differences

The two parts come from different manufacturers and target entirely different market segments. The AMD Instinct MI350P uses the MI350 128CU chip built on CDNA 4.0 architecture, fabricated on a 3 nm process at TSMC. The NVIDIA GeForce RTX 4070 Mobile uses the AD106 chip on Ada Lovelace architecture, fabricated on a 5 nm process, also at TSMC.

The transistor counts differ substantially. The MI350P packs 73,000 million transistors on a die size of 1190 mm², giving a transistor density of 61.3 million per square millimeter. The RTX 4070 Mobile contains 22,900 million transistors on a 188 mm² die, achieving a much higher density of 121.8 million per square millimeter. The density gap reflects the different design philosophies: the MI350P uses a massive interposer-based HBM design, while the RTX 4070 Mobile uses a conventional monolithic die with GDDR6 memory.

Clock speeds show the MI350P with a base of 1000 MHz and boost of 2200 MHz. The RTX 4070 Mobile runs a base of 1395 MHz and boost of 1695 MHz. The MI350P has a higher boost clock but a lower base clock, while the RTX 4070 Mobile starts from a higher baseline.

Memory configurations are radically different. The MI350P uses 144 GB of HBM3e across an 8192-bit bus, delivering 8.19 TB/s of bandwidth at 2000 MHz (8 Gbps effective). The RTX 4070 Mobile uses 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s at 2000 MHz (16 Gbps effective). The MI350P offers 32 times the memory capacity and roughly 32 times the bandwidth, though direct multiplication of these figures is not recorded in the database.

Compute resources also diverge. The MI350P has 8192 shading units and 512 texture mapping units, but zero ROPs and zero pixel rate. Its FP32 throughput is 36.04 TFLOPS, matching its FP16 at 36.04 TFLOPS (1:1). The texture rate reaches 1,126.4 GTexel/s. The RTX 4070 Mobile has 4608 shading units, 144 TMUs, 48 ROPs, 36 ray tracing cores, and 144 tensor cores. Its FP32 is 15.62 TFLOPS, also matching FP16 at 15.62 TFLOPS (1:1). The pixel rate is 81.36 GPixel/s and texture rate is 244.1 GTexel/s.

Ray tracing and tensor hardware exist only on the RTX 4070 Mobile. The MI350P lists null for both RT cores and tensor cores. This makes the NVIDIA part the only one with dedicated hardware for ray tracing and AI acceleration.

Power and physical characteristics differ sharply. The MI350P draws 600 W TDP, requires a 1000 W suggested PSU, uses a dual-slot cooler with a single 16-pin power connector, and measures 267 mm in length, 111 mm in height, and 40 mm in width. The RTX 4070 Mobile draws 115 W TDP, uses no power connectors (integrated into a laptop), is listed as IGP form factor, and has no recorded dimensions. The bus interfaces also differ: PCIe 5.0 x16 for the MI350P versus PCIe 4.0 x8 for the RTX 4070 Mobile.

Release dates place the RTX 4070 Mobile in January 2023, with the MI350P arriving much later in May 2026. The RTX 4070 Mobile is marked Active in production status, with predecessors in the GeForce 30 Mobile series and successors in the GeForce 50 Mobile series. The MI350P lists the Radeon Instinct as its predecessor and no successor.

The Verdict

The data supports a simple conclusion: these products do not compete. The AMD Instinct MI350P is a data center accelerator with no display outputs, no graphics API support, 144 GB of HBM3e memory, and 36.04 TFLOPS of FP32 compute. The NVIDIA GeForce RTX 4070 Mobile is a laptop GPU with full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, 8 GB of GDDR6, 36 ray tracing cores, and measured benchmark scores averaging 27435.

The RTX 4070 Mobile is the only part with any performance data. Its nearest rival comparisons show it performing at the level of the AMD Radeon RX 6700 XT and within 1.5 percent of the RTX 3090, RTX PRO 4000 Blackwell, and Radeon Pro Vega 20. The MI350P has no such data to compare.

The MI350P wins on raw specifications: memory capacity, memory bandwidth, FP32 throughput, transistor count, and die size. The RTX 4070 Mobile wins on efficiency, feature set, and measured performance. The 600 W TDP of the MI350P versus 115 W for the RTX 4070 Mobile shows the power gulf between the two designs.

For any workload requiring graphics output, ray tracing, or standard API compatibility, the RTX 4070 Mobile is the only viable option in this pairing. For memory-bound data center compute with enormous capacity and bandwidth, the MI350P offers specifications that the mobile part cannot approach.
