AMD Instinct MI350X vs Intel Arc Graphics 1 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no benchmark submissions for either the AMD Instinct MI350X or the Intel Arc Graphics 1 Xe Mobile. Both parts hold a percentile rank of 50 among all GPUs, with an average benchmark score of 0. Consequently, no head-to-head performance deltas, win counts, or comparative scores can be derived from the available measurements. The absence of benchmark data means that any performance relationship between these two accelerators remains unquantified in the database. Neither part has been subjected to the standardized test suite, so no score advantages, percentage leads, or performance deficits can be reported. The data simply does not permit a numerical comparison of execution speed, throughput, or frame rates. Without recorded scores, the head-to-head section must remain a statement of data availability rather than a performance verdict.

Architecture Differences

The AMD Instinct MI350X and Intel Arc Graphics 1 Xe Mobile represent fundamentally different design philosophies. The MI350X uses the CDNA 4.0 architecture, built for compute acceleration in data center environments. The Intel part employs Xe3-LPG, a low-power graphics architecture intended for integrated use in mobile systems. The AMD chip is designated MI350 256CU and belongs to the Instinct (MIx) generation, while the Intel chip is Wildcat Lake, part of the Arc Graphics-M (Wildcat Lake) generation.

Node technology differs despite both using 3 nm processes. AMD fabricates the MI350X at TSMC, whereas Intel builds the Arc Graphics 1 Xe Mobile at its own foundry, Intel. Transistor counts diverge sharply: the MI350X contains 185,000 million transistors on a 2380 mm² die, yielding a transistor density of 77.7M per mm². The Intel part lists its transistor count and die size as unknown in the database. The MI350X therefore presents a massive, high-density compute die, while the Intel solution uses an integrated design with unspecified physical dimensions.

The AMD accelerator deploys 16,384 shading units, 1,024 texture mapping units, and 0 ROPs. It has no ray tracing cores, no tensor cores, and its API support for DirectX, OpenGL, and Vulkan is marked as N/A. The Intel integrated GPU uses 128 shading units, 8 TMUs, 4 ROPs, and 1 ray tracing core. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This API support difference is striking: the MI350X exposes no graphics APIs at all, while the Intel part is a fully featured graphics solution.

Clock behavior also separates the two. The MI350X runs at a 1000 MHz base and 2200 MHz boost. The Intel part underclocks to 300 MHz base but boosts to 2300 MHz. Memory architecture could hardly be more different. The MI350X uses 288 GB of HBM3e on an 8192 bit bus, delivering 8.19 TB/s of bandwidth, with memory clocked at 2000 MHz (8 Gbps effective). The Intel part uses System Shared memory, with System Shared type, System Shared bus width, and System Dependent bandwidth. The AMD part is a dedicated accelerator with its own high-bandwidth memory stack, while the Intel part borrows system memory.

Compute rates reflect the design gap. The MI350X delivers 72.09 TFLOPS FP32 and the same 72.09 TFLOPS FP16 (1:1 ratio). The Intel part delivers 588.8 GFLOPS FP32 and 1,177.6 GFLOPS FP16 (2:1 ratio). The MI350X texture rate is 2,252.8 GTexel/s, while the Intel part manages 18.40 GTexel/s. Pixel rates tell a similar story: the MI350X is recorded at 0 MPixel/s, consistent with its lack of ROPs and display outputs, while the Intel part reaches 9.200 GPixel/s.

Power and physical design diverge completely. The MI350X has a 1000 W TDP, uses an OAM Module slot width, requires no power connectors, and lists a suggested PSU of 1400 W. It uses a PCIe 5.0 x16 bus interface and has no display outputs. Dimensions are 102 mm (4 inches) in length and 165 mm (6.5 inches) in width. The Intel part has a 25 W TDP, is an IGP with no power connectors, no suggested PSU, an IGP bus interface, and display outputs that are Portable Device Dependent. It has no recorded dimensions. The MI350X is a data center compute module with enormous power draw and memory capacity, while the Intel part is a low-power integrated GPU for mobile systems.

Where Each One Wins

The AMD Instinct MI350X wins decisively in raw compute throughput. Its 72.09 TFLOPS FP32 is 122 times higher than the Intel part's 588.8 GFLOPS FP32. Texture rate is 122 times higher at 2,252.8 GTexel/s versus 18.40 GTexel/s. Memory bandwidth is effectively infinite in comparison: 8.19 TB/s of dedicated HBM3e versus System Dependent shared memory. The MI350X supports 288 GB of memory, an enormous capacity for large datasets. Its 16,384 shading units and 1,024 TMUs provide massive parallel processing resources. The 1000 W TDP and 1400 W suggested PSU indicate a design meant for sustained heavy compute loads in server racks.

The Intel Arc Graphics 1 Xe Mobile wins in practical graphics capability. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it usable for modern graphics workloads. The MI350X lists N/A for all graphics APIs, meaning no DirectX, OpenGL, or Vulkan support. The Intel part provides 4 ROPs and 1 ray tracing core, enabling pixel output and ray-traced effects that the MI350X cannot perform (0 ROPs, no RT cores). The 9.200 GPixel/s pixel rate confirms its ability to drive displays, while the MI350X has no display outputs at all. The Intel part operates at 25 W TDP, suitable for battery-powered devices, while the MI350X needs 1000 W. The Intel part also wins on clock boost, reaching 2300 MHz versus 2200 MHz for the AMD part, though this is irrelevant given the massive architectural differences.

The production status also favors the Intel part, which is recorded as Active. The MI350X has no production status listed. The Intel part was released on 2026-04-15, while the MI350X has a release date of 2025-06-11. The MI350X is the earlier product, but its status is unconfirmed.
