AMD Instinct MI350P vs NVIDIA RTX 3500 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for this pairing. Both the AMD Instinct MI350P and the NVIDIA RTX 3500 Mobile Ada Generation show empty benchmark arrays, zero win counts on each side, and an average benchmark score of zero for both. This absence of measured data means any comparative performance assessment must be derived entirely from architectural specifications rather than empirical test results.

The lack of benchmark data is notable given the disparity in raw compute resources. The MI350P carries 8,192 shading units against 5,120 for the RTX 3500 Mobile, and its FP32 throughput is recorded at 36.04 TFLOPS versus 15.82 TFLOPS for the NVIDIA part. That represents a 2.28x advantage in theoretical single-precision compute for the AMD accelerator. Texture rate follows a similar pattern, with the MI350P delivering 1,126.4 GTexel/s compared to 247.2 GTexel/s, a 4.56x difference. Pixel rate, however, tells the opposite story: the RTX 3500 Mobile outputs 98.88 GPixel/s while the MI350P records 0 MPixel/s, reflecting the AMD card's lack of any display output capability.

Memory bandwidth strongly favors the MI350P at 8.19 TB/s versus 432.0 GB/s, a factor of roughly 19x. The memory bus width difference is equally stark: 8,192 bit against 192 bit. These specification gaps suggest the MI350P is designed for a fundamentally different workload class, but without benchmark scores in the database, the practical impact remains unquantified. The percentile ranking for both parts sits at 50, placing each in the middle of all recorded GPUs, though this figure carries limited meaning when no actual scores accompany it.

Architecture Differences

The two accelerators come from different architectural lineages. AMD's MI350P uses CDNA 4.0, built on a 3 nm process at TSMC with 73,000 million transistors on a 1,190 mm² die. NVIDIA's RTX 3500 Mobile uses Ada Lovelace, fabbed on a 5 nm process also at TSMC, with 35,800 million transistors on a 294 mm² die. Transistor density reflects this: the MI350P achieves 61.3M transistors per mm², while the RTX 3500 Mobile reaches 121.8M per mm², nearly double despite the older node, a consequence of the MI350P's very large physical die.

Memory architecture diverges sharply. The MI350P packs 144 GB of HBM3e on an 8,192-bit bus, while the RTX 3500 Mobile uses 12 GB of GDDR6 on a 192-bit bus. The MI350P's memory clock is listed at 2000 MHz with 8 Gbps effective transfer, against 2250 MHz with 18 Gbps effective for the NVIDIA part. The much wider bus on the AMD accelerator drives its enormous bandwidth advantage.

Core organization differs as well. The MI350P has 512 texture mapping units and zero ROPs, consistent with a compute-focused design that skips traditional rasterization output stages. The RTX 3500 Mobile has 160 TMUs and 64 ROPs, plus 40 ray tracing cores and 160 tensor cores, features entirely absent from the AMD specification. The MI350P lists no RT or tensor core counts at all. FP16 performance matches FP32 at a 1:1 ratio on both cards, but the absolute values differ by the same 2.28x margin as FP32.

Clock speeds show a different tradeoff. The RTX 3500 Mobile runs at a 1110 MHz base and 1545 MHz boost, while the MI350P starts at 1000 MHz base but boosts to 2200 MHz. The NVIDIA card's lower boost clock is offset by its smaller, denser design and mobile power envelope. Power consumption diverges dramatically: the MI350P draws 600 W with a suggested 1000 W power supply and a single 16-pin connector, while the RTX 3500 Mobile consumes 100 W with no external power connectors at all, listed as an IGP form factor. The MI350P is a dual-slot, 267 mm long, 111 mm tall, 40 mm wide card; the RTX 3500 Mobile has no recorded dimensions.

API support separates the two clearly. The MI350P lists N/A for DirectX, OpenGL, and Vulkan, while the RTX 3500 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part has no display outputs; the NVIDIA part's outputs are portable device dependent. Bus interfaces also differ: PCIe 5.0 x16 for the MI350P, PCIe 4.0 x16 for the RTX 3500 Mobile.

Where Each One Wins

Based on the specification data, the MI350P wins decisively in compute throughput, memory capacity, memory bandwidth, and texture processing. Its 36.04 TFLOPS FP32, 144 GB HBM3e, 8.19 TB/s bandwidth, and 1,126.4 GTexel/s texture rate position it for large-scale data center workloads where raw arithmetic and memory access dominate. The 8192-bit bus width is the clearest indicator of this intent: no mobile GPU approaches that memory interface. The lack of display outputs and zero pixel rate confirm the MI350P is not meant for any rasterization task.

The RTX 3500 Mobile wins in every area tied to graphics output and general-purpose mobile use. Its 98.88 GPixel/s pixel rate, 40 RT cores, 160 tensor cores, and full API support make it functional for rendering, ray tracing, and graphics APIs. The 100 W TDP and IGP form factor allow deployment in portable systems, which the MI350P's 600 W dual-slot design cannot match. The RTX 3500 Mobile's PCIe 4.0 interface is older but sufficient for a mobile part, and its GDDR6 memory, while much slower at 432.0 GB/s, is standard for notebook implementations.

Release timing also differs: the MI350P carries a release date of 2026-05-06, while the RTX 3500 Mobile shipped on 2023-03-20. The NVIDIA part is marked as production status Active, with a predecessor of Ampere-MW and a successor of Blackwell-MW. The MI350P lists no production status and names Radeon Instinct as its predecessor. This suggest the MI350P is a newer, forward-looking accelerator while the RTX 3500 Mobile is an established mobile product in an active product line.

The Verdict

The recorded data supports a clear division: the AMD Instinct MI350P is a data center compute accelerator, and the NVIDIA RTX 3500 Mobile Ada Generation is a mobile graphics processor. No benchmark scores exist to blur this distinction. The MI350P offers 2.28x the FP32 throughput, 12x the memory capacity, and roughly 19x the memory bandwidth of the RTX 3500 Mobile, but it consumes 6x the power, occupies a dual-slot form factor, and supports no graphics APIs or display outputs. The RTX 3500 Mobile offers pixel rendering, ray tracing, tensor operations, API compatibility, and a 100 W envelope suitable for laptops.

For workloads centered on massive matrix computation, large memory-resident datasets, or high-bandwidth streaming, the MI350P's specifications indicate it would outperform the RTX 3500 Mobile by wide margins. For any task requiring graphics output, real-time rendering, or deployment in a portable chassis, the RTX 3500 Mobile is the only viable option between the two. The data does not suggest these products compete in the same market segment; they target different physical environments and computational roles. The MI350P's 3 nm node and newer release date point to a latest-generation server accelerator, while the RTX 3500 Mobile's 5 nm node and 2023 release date place it in an established mobile lineup. Buyers should select based on the form factor and workload requirements, not on direct performance equivalence, since the database contains no head-to-head results to indicate otherwise.
