AMD Instinct MI308X vs Intel Arc Graphics 112EU Mobile Comparison

AMD Instinct MI308X and Intel Arc Graphics 112EU Mobile occupy opposite extremes of the GPU spectrum. The database records no shared benchmark entries between them, so their comparative standing derives from architectural specifications, raw throughput figures, and the distinct roles each part is designed to serve. One is a data center accelerator built for massive parallel computation, while the other is an integrated graphics solution for portable devices. This analysis breaks down where each unit wins, how their architectures differ, and what the recorded data indicates about their respective capabilities.

Where Each One Wins

The AMD Instinct MI308X is constructed for compute workloads that demand enormous memory capacity and extreme floating-point throughput. Its recorded specifications show 19,456 shading units, 1,216 texture mapping units, and a peak FP32 rate of 81.72 TFLOPS. The Intel Arc Graphics 112EU Mobile, by contrast, delivers 896 shading units, 56 texture mapping units, and 3.942 TFLOPS of FP32 performance. The MI308X holds a decisive advantage in every raw compute metric, making it the appropriate choice for high-performance computing, AI training, and scientific simulation where massive parallel processing is essential.

The Intel part wins in the mobile integrated graphics segment. It offers 24 raster operation units with a pixel rate of 52.80 GPixel/s, whereas the MI308X records a pixel rate of 0 MPixel/s. The AMD accelerator has no display outputs, making it unsuitable for rendering to a screen. The Intel Arc Graphics 112EU Mobile is an IGP with display outputs described as Portable Device Dependent, meaning it is designed to drive internal laptop panels and external monitors. For everyday graphics, video playback, and light gaming on a portable system, the Intel solution is the functional choice.

The MI308X delivers a texture rate of 2,553.6 GTexel/s, which is more than 20 times the 123.2 GTexel/s of the Intel part. Memory bandwidth further separates them: the AMD accelerator provides 5.32 TB/s from 192 GB of HBM3 across an 8192-bit bus, while the Intel IGP uses System Shared memory with System Dependent bandwidth. The MI308X also supports PCIe 5.0 x16, while the Intel part connects via Ring Bus. Each unit wins in its intended domain: the MI308X for data center compute throughput, the Intel Arc for integrated mobile graphics functionality.

Architecture Differences

The MI308X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture. It is manufactured on a 5 nm process at TSMC, with 153,000 million transistors on a 1017 mm² die. The transistor density is recorded as 150.4M per mm². The Intel Arc Graphics 112EU Mobile uses the Meteor Lake chip based on Xe-LPG architecture, fabricated on a 10 nm process at Intel. The database does not list transistor count, die size, or transistor density for the Intel part.

The memory subsystems could not be more different. The MI308X has 192 GB of HBM3 memory with an 8192-bit bus and 5.32 TB/s bandwidth. The Intel Arc Graphics 112EU Mobile uses System Shared memory, meaning it draws from the host system's main memory rather than having dedicated VRAM. Its bus width and bandwidth are likewise System Shared and System Dependent, respectively. This reflects the fundamental design split between a discrete accelerator with dedicated high-bandwidth memory and an integrated GPU that shares system resources.

Clock behavior also differs. The MI308X runs at a 1000 MHz base clock and 2100 MHz boost clock, with memory at 1300 MHz or 5.2 Gbps effective. The Intel part has a 300 MHz base clock and 2200 MHz boost clock. Despite the similar boost clocks, the MI308X processes far more data per clock due to its 19,456 shading units versus 896.

API support separates the two as well. The Intel Arc Graphics 112EU Mobile supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The MI308X records N/A for DirectX, OpenGL, and Vulkan, indicating it is not designed for conventional graphics API workloads. The Intel part also has a production status of Active, while the MI308X does not list a production status. The MI308X slots as an OAM Module with no power connectors, while the Intel part is an IGP. The AMD accelerator has a 750 W TDP and a suggested PSU of 1150 W, while the Intel IGP draws 65 W with no suggested PSU recorded.

Head-to-Head Benchmarks

No head-to-head benchmark entries exist in the database for these two products. The wins column shows zero for both sides, and the average benchmark score is zero for each. Direct comparison is therefore impossible from measured results. The available data is purely specification-based, which nevertheless provides a clear picture of relative capability.

The FP32 throughput gap is the most striking differentiator. The MI308X delivers 81.72 TFLOPS, which is 20.7 times the 3.942 TFLOPS of the Intel Arc Graphics 112EU Mobile. In FP16, the MI308X again records 81.72 TFLOPS with a 1:1 ratio, while the Intel part achieves 7.885 TFLOPS with a 2:1 ratio. The AMD accelerator leads by roughly 10.4 times in FP16. These figures indicate that the MI308X is engineered for compute-heavy tasks where precision and raw throughput are paramount, while the Intel IGP targets efficiency within a 65 W envelope.

Texture throughput follows the same pattern. The MI308X reaches 2,553.6 GTexel/s against 123.2 GTexel/s for the Intel part, a factor of about 20.7. The pixel rate reverses the trend: the Intel Arc Graphics 112EU Mobile records 52.80 GPixel/s, while the MI308X lists 0 MPixel/s. The AMD accelerator has no ROPs, whereas the Intel part has 24. This means the MI308X cannot perform traditional rasterization output, while the Intel IGP is fully capable of pixel generation for display purposes.

Memory bandwidth separates the two by an even wider margin. The MI308X provides 5.32 TB/s, while the Intel part's bandwidth is System Dependent, which in practice is limited by the host platform's memory architecture. The 192 GB capacity of the MI308X versus System Shared for the Intel part reinforces the intended use cases: large model inference and data-intensive workloads on the AMD side, lightweight mobile graphics on the Intel side.

The shading unit count is 21.7 times higher on the MI308X (19,456 versus 896). Texture mapping units are 21.7 times higher as well (1,216 versus 56). These ratios align closely with the FP32 and texture rate differences, confirming that the MI308X scales its compute resources uniformly. The Intel part compensates with a higher boost clock relative to its base, but the architectural gap is too large to overcome.

Both products share a release window in December 2023. The MI308X launched on December 5, 2023, and the Intel Arc Graphics 112EU Mobile followed on December 13, 2023. They represent contemporaneous designs aimed at entirely different markets. The MI308X belongs to the Instinct (MIx) generation with a predecessor of Radeon Instinct, while the Intel part is in the Arc Graphics-M (Meteor Lake) generation with a predecessor of HD Graphics-M.
