AMD Instinct MI350P vs NVIDIA GeForce RTX 5070 Mobile Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison, as the AMD Instinct MI350P has no benchmark entries in the database, while the NVIDIA GeForce RTX 5070 Mobile has nine recorded test scores. The head-to-head benchmark table is empty, meaning there are no direct comparative measurements between these two accelerators. What the data does provide is a full benchmark profile for the RTX 5070 Mobile and a percentile ranking for the MI350P that places it at the 50th percentile against all GPUs, compared to the RTX 5070 Mobile's 75th percentile ranking.

The RTX 5070 Mobile's Geekbench OpenCL score of 122,238 and its Vulkan score of 116,960 represent the strongest recorded results in its benchmark suite. These scores indicate substantial compute capability in cross-platform workloads. The PassMark G3D score of 20,355 is the highest of its PassMark results, with the GPU compute score of 8,279 trailing significantly behind, suggesting that the card's rasterization performance outpaces its compute throughput in that specific test suite. The DirectX tests show a spread from 93 in DirectX 12 to 214 in DirectX 9, with DirectX 11 at 192 and DirectX 10 at 129, indicating that legacy API performance is stronger than modern API performance for this mobile part.

The RTX 5070 Mobile's average benchmark score of 29,928 places it in a tight cluster with its nearest rivals. The NVIDIA GeForce RTX 3070 Ti scores 29,945, a mere 0.1% higher, while the RTX 2080 Ti scores 29,783, which is 0.5% lower. The AMD Radeon RX 6800 scores 30,095, putting it 0.6% ahead, and the AMD Radeon RX 6700 scores 30,433, leading by 1.7%. These delta percentages, all within a 2.3% band, indicate that the RTX 5070 Mobile delivers performance essentially equivalent to these desktop-class rivals despite its mobile form factor and 50 W power envelope.

The MI350P, with no benchmark scores and an average benchmark score of zero, cannot be compared numerically on any test. Its 50th percentile ranking against all GPUs is a database categorization that does not derive from measured scores in the same manner as the RTX 5070 Mobile's 75th percentile, which is backed by actual recorded results. The percentile for the MI350P appears to be an estimate based on its specifications rather than empirical testing.

What the data does show is that the RTX 5070 Mobile's recorded performance is consistent with a mobile GPU that competes with desktop cards from previous generations. The 0.1% deficit to the RTX 3070 Ti and the 0.5% advantage over the RTX 2080 Ti place it squarely between those two architectures in the database's measurements. The 0.6% and 1.7% deficits to the RX 6800 and RX 6700 respectively show that AMD's desktop RDNA2 parts hold a slim edge in the recorded averages.

The Verdict

The data supports a clear division of roles between these two devices, though the absence of MI350P benchmark scores limits the comparison to specification-based analysis. The RTX 5070 Mobile is a measured performer, with nine benchmark results and a 75th percentile standing against all GPUs. Its average score of 29,928 puts it within 1.7% of the AMD Radeon RX 6700, which is its closest rival in the database with a 1.7% lead. The mobile card's nearest rivals are all desktop components, which indicates that its performance class is comparable to desktop GPUs from the Ampere and RDNA2 generations.

The MI350P, by contrast, has zero recorded benchmark scores and sits at the 50th percentile. This placement in the database suggests it is positioned as a mid-pack performer among all GPUs, but without measurements, that ranking cannot be validated against the RTX 5070 Mobile's empirical results. The MI350P targets a different application space entirely, as evidenced by its lack of display outputs, its dual-slot cooler, and its 600 W power draw.

For workloads that require graphics output, the RTX 5070 Mobile is the only viable option in this comparison, as the MI350P has no display outputs at all. For compute-intensive tasks in a server or datacenter context, the MI350P's specifications point toward massive memory capacity and bandwidth, but the data does not include any benchmark confirmation of its compute performance. The RTX 5070 Mobile's PassMark GPU compute score of 8,279 is modest relative to its G3D score, and its 13.13 TFLOPS FP32 rating is less than half the MI350P's 36.04 TFLOPS.

The RTX 5070 Mobile's 50 W TDP and IGP form factor make it suitable for portable devices, while the MI350P's 600 W TDP and dual-slot design require a desktop or server chassis with substantial power delivery, including a suggested PSU of 1000 W. The database shows no benchmark overlap, so the verdict rests on intended use: the RTX 5070 Mobile for portable graphics and gaming, the MI350P for high-capacity compute acceleration where its 144 GB memory and 8.19 TB/s bandwidth are the defining attributes.

Architecture Differences

The two chips diverge fundamentally in architecture, process technology, and design goals. The AMD Instinct MI350P uses CDNA 4.0 architecture on a 3 nm process node from TSMC, while the NVIDIA GeForce RTX 5070 Mobile uses Blackwell 2.0 architecture on a 5 nm node, also from TSMC. The MI350P's die measures 1190 mm² with 73,000 million transistors, resulting in a transistor density of 61.3 million per square millimeter. The RTX 5070 Mobile's GB206 chip is dramatically smaller at 181 mm² with 21,900 million transistors, yielding a higher density of 121.0 million per square millimeter. The density difference reflects the MI350P's massive die area dedicated to memory controllers and compute units rather than density optimization.

The MI350P packs 8192 shading units, 512 texture mapping units, and zero ROPs, which aligns with its compute-focused design where pixel output is not required. Its pixel rate is recorded as 0 MPixel/s, and its texture rate reaches 1,126.4 GTexel/s. The RTX 5070 Mobile has 4608 shading units, 144 TMUs, and 48 ROPs, with a pixel rate of 68.40 GPixel/s and a texture rate of 205.2 GTexel/s. The MI350P's texture rate is over five times higher, but its lack of ROPs means it cannot rasterize graphics.

Ray tracing and tensor hardware differ as well. The MI350P lists no RT cores and no tensor cores in the data, while the RTX 5070 Mobile includes 36 RT cores and 144 tensor cores. These features enable the NVIDIA part to accelerate ray-traced graphics and AI workloads through dedicated hardware, capabilities the MI350P does not expose in its specification sheet. The FP32 compute figures reinforce the divide: the MI350P delivers 36.04 TFLOPS, and the RTX 5070 Mobile delivers 13.13 TFLOPS, both with 1:1 FP16 ratios.

Memory architecture is the most pronounced difference. The MI350P uses 144 GB of HBM3e on an 8192-bit bus, achieving 8.19 TB/s of bandwidth. The RTX 5070 Mobile uses 8 GB of GDDR7 on a 128-bit bus, with 384.0 GB/s of bandwidth. The MI350P's memory bandwidth is more than 21 times higher, and its capacity is 18 times larger. The memory clock rates are recorded as 2000 MHz with 8 Gbps effective for the MI350P, and 1500 MHz with 24 Gbps effective for the RTX 5070 Mobile. The base and boost clocks also differ substantially: the MI350P runs at 1000 MHz base and 2200 MHz boost, while the RTX 5070 Mobile runs at 907 MHz base and 1425 MHz boost.

API support separates the two as well. The MI350P lists DirectX, OpenGL, and Vulkan as N/A, meaning it does not support graphics APIs. The RTX 5070 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This confirms the MI350P's role as a pure compute accelerator with no graphics pipeline, while the RTX 5070 Mobile is a full-featured graphics processor.

Where Each One Wins

The RTX 5070 Mobile wins in every measured benchmark category, simply because it is the only one of the two with recorded scores. Its Geekbench OpenCL score of 122,238 and Vulkan score of 116,960 demonstrate strong cross-vendor compute performance. Its PassMark G3D score of 20,355 indicates solid rasterization capability, and its PassMark GPU compute score of 8,279 shows moderate compute throughput in that specific test. The DirectX suite, ranging from 93 in DirectX 12 to 214 in DirectX 9, shows that the card performs better on legacy APIs, which may reflect driver optimization priorities for older workloads.

The MI350P wins on raw specification counts. Its 8192 shading units double the RTX 5070 Mobile's 4608. Its 512 TMUs more than triple the NVIDIA part's 144. Its texture rate of 1,126.4 GTexel/s is roughly 5.5 times the 205.2 GTexel/s of the RTX 5070 Mobile. The 144 GB memory capacity and 8.19 TB/s bandwidth are in a different class entirely from the 8 GB and 384.0 GB/s of the mobile card. The 36.04 TFLOPS FP32 rating is 2.7 times the 13.13 TFLOPS of the RTX 5070 Mobile.

The power envelope tells a complementary story. The RTX 5070 Mobile's 50 W TDP makes it suitable for laptops and portable devices, where the MI350P's 600 W TDP would be impossible to accommodate. The MI350P's dual-slot width and 267 mm length require a full-size chassis, while the RTX 5070 Mobile is an IGP with no dimensions listed and no power connectors. The MI350P also carries a suggested PSU of 1000 W, underscoring its datacenter orientation.

The RTX 5070 Mobile's 75th percentile ranking against all GPUs, backed by nine benchmark scores, gives it a validated performance position. The MI350P's 50th percentile is an unverified estimate with no supporting measurements. In practical terms, the RTX 5070 Mobile wins for any workload that needs graphics output, ray tracing, or DirectX/Vulkan support. The MI350P wins for workloads that demand massive memory capacity, extreme bandwidth, and high FP32 throughput in a compute-only environment.
