AMD Instinct MI350P vs Intel Arc Graphics 2 Xe Mobile Comparison

The Verdict

The AMD Instinct MI350P and Intel Arc Graphics 2 Xe Mobile occupy opposite ends of the GPU spectrum, and the recorded data reflects this starkly. The MI350P is a dual-slot, 600 W accelerator with 8,192 shading units, 144 GB of HBM3e memory, and an 8,192-bit bus, built for high-throughput compute workloads. The Arc Graphics 2 Xe Mobile is a 25 W integrated processor with 256 shading units, 8 ROPs, and system-shared memory, designed for portable devices. The data shows no benchmark overlap: the MI350P has no display outputs and no API support, while the Intel part supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Any user needing a rendering-capable, API-compliant GPU for a laptop must choose the Intel part. Any workload requiring massive memory bandwidth and raw FP32 throughput, such as AI training or scientific simulation, points to the AMD accelerator. The MI350P delivers 36.04 TFLOPS FP32 versus the Intel part's 1,280.0 GFLOPS, a 28-fold difference in raw compute. The MI350P also provides 8.19 TB/s of memory bandwidth, while the Intel part's bandwidth is system dependent, meaning it shares main memory and cannot match a dedicated HBM3e stack.

Architecture Differences

The two GPUs use fundamentally different processor designs. The AMD Instinct MI350P is built on CDNA 4.0 architecture, a compute-optimized design with 73,000 million transistors on a 3 nm TSMC process, occupying a 1190 mm² die. The transistor density is 61.3 million transistors per square millimeter. The chip is designated MI350 128CU, indicating 128 compute units. The Intel Arc Graphics 2 Xe Mobile uses Xe3-LPG architecture, built on a 3 nm Intel process, with the chip codenamed Wildcat Lake. Its transistor count and die size are recorded as unknown in the database.

The MI350P has 8,192 shading units, 512 texture mapping units, and zero ROPs, a configuration that prioritizes compute throughput over pixel output. Its pixel rate is recorded as 0 MPixel/s, and its texture rate is 1,126.4 GTexel/s. The Intel part has 256 shading units, 16 TMUs, and 8 ROPs, with a pixel rate of 20.00 GPixel/s and a texture rate of 40.00 GTexel/s. The Intel GPU also includes 2 ray tracing cores, while the MI350P has no RT cores listed. Neither GPU lists tensor cores in the database.

Memory architecture differs completely. The MI350P uses dedicated HBM3e memory with 144 GB capacity, an 8,192-bit bus, and 8.19 TB/s bandwidth. The Intel part uses system-shared memory, meaning the GPU accesses the same memory pool as the CPU, with bandwidth and bus width both listed as system dependent. The MI350P's memory clock is 2000 MHz with 8 Gbps effective data rate, while the Intel part's memory clock is listed as system shared.

The MI350P uses a PCIe 5.0 x16 bus interface and requires a 16-pin power connector with a 600 W TDP. The Arc Graphics 2 Xe Mobile uses an integrated graphics processor (IGP) bus interface, draws no power from external connectors, and has a 25 W TDP. The MI350P has no display outputs, while the Intel part's display outputs are listed as portable device dependent, meaning they rely on the host laptop's display system.

Specification Differences

The database records distinct values for nearly every specification category. The MI350P has a base clock of 1000 MHz and a boost clock of 2200 MHz, versus the Intel part's base clock of 300 MHz and boost clock of 2500 MHz. Though the Intel part has a higher boost clock, its shading unit count is far lower.

FP16 performance differs in ratio. The MI350P delivers 36.04 TFLOPS FP16 at a 1:1 ratio relative to FP32. The Intel part delivers 2.560 TFLOPS FP16 at a 2:1 ratio, meaning its FP16 throughput is double its FP32 rate of 1,280.0 GFLOPS.

Process node and foundry differ: both use 3 nm processes, but the MI350P is fabricated by TSMC, while the Intel part is fabricated by Intel. Transistor counts are 73,000 million for the MI350P and unknown for the Intel part. Die size is 1190 mm² for the MI350P and unknown for the Intel part.

The MI350P's production status is not recorded, while the Intel part is listed as active. The MI350P's predecessor is Radeon Instinct, and the Intel part's predecessor is HD Graphics-M. Both have no successor listed in the database.

The MI350P supports no graphics APIs, while the Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI350P has no display outputs; the Intel part's outputs depend on the host portable device. The MI350P is a dual-slot card with dimensions of 267 mm length, 111 mm height, and 40 mm width; the Intel part is an IGP with no dimensions recorded.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs, and neither part has recorded benchmark scores. Both have a percentile rank of 50 among all GPUs, and both have an average benchmark score of 0. The nearest rivals lists are empty for both items, and the win counts are 0 for each GPU. This absence of measured performance data means the comparison must rely on the recorded specifications.

The most decisive specification gap is FP32 throughput. The MI350P delivers 36.04 TFLOPS, while the Intel part delivers 1,280.0 GFLOPS. This is a 28.2-fold difference in the MI350P's favor. For FP16, the MI350P delivers 36.04 TFLOPS at a 1:1 ratio, while the Intel part delivers 2.560 TFLOPS at a 2:1 ratio, a 14.1-fold difference. Texture rate favors the MI350P at 1,126.4 GTexel/s versus 40.00 GTexel/s, a 28.2-fold difference. Pixel rate, however, favors the Intel part: 20.00 GPixel/s versus 0 MPixel/s for the MI350P, which has no ROPs and no pixel output capability.

Memory bandwidth shows the largest gap. The MI350P's 8.19 TB/s from HBM3e memory is a fixed, dedicated resource. The Intel part's bandwidth is system dependent, meaning it shares main memory bandwidth with the CPU and cannot be compared as a fixed value. Memory capacity also differs absolutely: 144 GB dedicated versus system-shared, with the shared pool's capacity dependent on the host system's RAM.

Clock speeds show a nuanced picture. The Intel part has a higher boost clock at 2500 MHz versus 2200 MHz for the MI350P. The base clocks differ in the opposite direction: 1000 MHz for the MI350P versus 300 MHz for the Intel part. The higher boost clock on the Intel part does not compensate for its 32 times fewer shading units (256 versus 8,192).

Power consumption is another major divergence. The MI350P is rated at 600 W TDP with a 1000 W suggested PSU, while the Intel part is rated at 25 W TDP with no PSU requirement. The MI350P's power draw is 24 times higher, which correlates with its use of a dedicated dual-slot cooler and 16-pin power connector. The Intel part uses no power connectors and is an integrated processor.

API support is a binary differentiator. The Intel part supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, enabling modern graphics workloads and gaming. The MI350P lists no API support for any of these, and it has no display outputs, making it unsuitable for any interactive graphics or rendering task that requires a display or standard graphics API.

Ray tracing capability exists only on the Intel part, which has 2 dedicated RT cores. The MI350P has no RT cores listed, reinforcing its role as a compute accelerator rather than a graphics renderer. The Intel part's 8 ROPs and 20.00 GPixel/s pixel rate confirm its ability to drive display output, while the MI350P's 0 ROPs and 0 MPixel/s pixel rate confirm it cannot.

Release timing is close: the Intel part launched April 15, 2026, and the MI350P launched May 6, 2026. Both are 3 nm parts, but from different foundries and with different transistor budgets. The MI350P's 73,000 million transistors on a 1190 mm² die give it a density of 61.3 million per square millimeter, while the Intel part's transistor count and die size remain undisclosed in the database.
