AMD Instinct MI350P vs NVIDIA RTX 4000 Mobile Ada Generation Comparison

Where Each One Wins

The recorded data separates these two accelerators into entirely different deployment classes. The AMD Instinct MI350P is a data center compute card with no display outputs, while the NVIDIA RTX 4000 Mobile Ada Generation is an integrated graphics processor for portable workstations. The benchmark results show zero direct head-to-head wins for either product, as their target workloads do not overlap in any measurable way.

The MI350P carries 8192 shading units, 512 texture mapping units, and zero ROPs, which indicates a pure compute configuration optimized for throughput rather than rasterization. Its pixel rate is recorded as 0 MPixel/s, confirming that the card does not perform traditional graphics output. The RTX 4000 Mobile, by contrast, delivers 80 ROPs and a pixel rate of 133.2 GPixel/s, along with 58 RT cores and 232 tensor cores, making it the only one of the two with hardware support for ray tracing, tensor operations, and the DirectX 12 Ultimate API set.

In floating point throughput, the MI350P records 36.04 TFLOPS for both FP32 and FP16, while the RTX 4000 Mobile records 24.72 TFLOPS for both. The MI350P leads in raw compute density, but the RTX 4000 Mobile provides graphics features that the AMD card simply lacks. The data shows a 46 percent FP32 advantage for the MI350P, but that advantage comes without any display pipeline, rasterization hardware, or graphics API support.

Texture throughput follows the same pattern. The MI350P reaches 1,126.4 GTexel/s against 386.3 GTexel/s for the RTX 4000 Mobile, a 192 percent gap. Yet the RTX 4000 Mobile counters with 133.2 GPixel/s of pixel throughput where the MI350P records zero. The verdict from the data is straightforward: the MI350P wins any compute-only workload, and the RTX 4000 Mobile wins every graphics-oriented workload by default.

Architecture Differences

The two chips come from different foundry nodes and design philosophies. The MI350P uses a 3 nm TSMC process with 73,000 million transistors on a 1190 mm² die, yielding a transistor density of 61.3 million transistors per square millimeter. The RTX 4000 Mobile uses a 5 nm TSMC process with 35,800 million transistors on a 294 mm² die, yielding 121.8 million transistors per square millimeter. The RTX 4000 Mobile packs more than twice the transistor density into a die that is roughly one quarter the size.

The MI350P uses the CDNA 4.0 architecture on the MI350 128CU chip, which is part of AMD's Instinct (MIx) generation. The RTX 4000 Mobile uses the Ada Lovelace architecture on the AD104 chip, part of NVIDIA's GeForce 40-series and the Ada-MW generation. The MI350P has no RT cores and no tensor cores listed, while the RTX 4000 Mobile includes 58 RT cores and 232 tensor cores.

Memory architecture is another major divide. The MI350P uses 144 GB of HBM3e on an 8192-bit bus with 8.19 TB/s of bandwidth. The RTX 4000 Mobile uses 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s of bandwidth. The MI350P has 12 times the memory capacity and approximately 19 times the memory bandwidth. The RTX 4000 Mobile relies on a conventional GDDR6 memory clock of 2250 MHz (18 Gbps effective), whereas the MI350P memory runs at 2000 MHz (8 Gbps effective) but across a vastly wider bus.

Clock behavior differs as well. The RTX 4000 Mobile has a higher base clock at 1290 MHz versus 1000 MHz, but the MI350P has a higher boost clock at 2200 MHz versus 1665 MHz. The RTX 4000 Mobile reports a pixel rate of 133.2 GPixel/s and a texture rate of 386.3 GTexel/s. The MI350P reports a texture rate of 1,126.4 GTexel/s and a pixel rate of zero.

API support separates them completely. The MI350P lists DirectX, OpenGL, and Vulkan as N/A. The RTX 4000 Mobile lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI350P has no display outputs, while the RTX 4000 Mobile outputs are described as Portable Device Dependent.

Head-to-Head Benchmarks

The database contains no overlapping benchmark entries, so the comparison relies on the recorded performance fields rather than application-level tests. The largest single advantage for the MI350P appears in memory bandwidth, where 8.19 TB/s is roughly 19 times the 432.0 GB/s of the RTX 4000 Mobile. Texture rate shows a similarly wide gap: 1,126.4 GTexel/s against 386.3 GTexel/s, a 192 percent difference. FP32 and FP16 throughput both favor the MI350P at 36.04 TFLOPS versus 24.72 TFLOPS, a 46 percent lead.

The RTX 4000 Mobile holds its ground in the graphics-specific fields. Its pixel rate of 133.2 GPixel/s exceeds the MI350P's 0 MPixel/s by definition, and it carries 80 ROPs against zero. The RT core count of 58 and tensor core count of 232 are entirely absent from the MI350P's specifications. The RTX 4000 Mobile also runs at a 1290 MHz base clock, 290 MHz higher than the MI350P's 1000 MHz base, though the MI350P boost clock of 2200 MHz tops the RTX 4000 Mobile's 1665 MHz by 535 MHz.

The RTX 4000 Mobile achieves a higher transistor density at 121.8M / mm² versus 61.3M / mm², which reflects the smaller 294 mm² die. The MI350P compensates with a 1190 mm² die and 73,000 million transistors, more than double the RTX 4000 Mobile's 35,800 million. Power consumption scales with that silicon budget: the MI350P draws 600 W against 110 W for the mobile part, a 490 W difference. The RTX 4000 Mobile requires no external power connectors, while the MI350P requires a 1x 16-pin connector and a 1000 W suggested PSU.

Both products sit at the 50th percentile among all GPUs in the database, and both have an average benchmark score of zero. Their nearest rivals lists are empty. The percentile tie does not indicate equal performance; it reflects the absence of comparable benchmark data for either product.

The Verdict

The data defines two non-overlapping products. The AMD Instinct MI350P is a 600 W, dual-slot, PCIe 5.0 x16 accelerator with 144 GB of HBM3e, 8192 shading units, no display outputs, and no graphics API support. It delivers 36.04 TFLOPS of FP32 compute, 1,126.4 GTexel/s of texture throughput, and 8.19 TB/s of memory bandwidth. It is built for compute-heavy data center workloads where graphics output is irrelevant.

The NVIDIA RTX 4000 Mobile Ada Generation is a 110 W integrated GPU with 7424 shading units, 58 RT cores, 232 tensor cores, 80 ROPs, 12 GB of GDDR6, and full DirectX 12 Ultimate support. It delivers 24.72 TFLOPS of FP32, 133.2 GPixel/s of pixel throughput, and 432.0 GB/s of memory bandwidth. It is built for portable workstations where graphics rendering, ray tracing, and display output are required.

The selection logic follows the specifications. A workload that needs HBM3e capacity, multi-terabyte memory bandwidth, or peak FP32 throughput on a server board points to the MI350P. A workload that needs rasterization, ray tracing, tensor operations, or a mobile form factor points to the RTX 4000 Mobile. The MI350P is the compute specialist; the RTX 4000 Mobile is the graphics specialist. The recorded data offers no scenario where both are viable alternatives for the same task.
