Where Each One Wins

The AMD Instinct MI308X is built for server and datacenter workloads where raw compute throughput and memory capacity dominate. Its 192 GB of HBM3 memory with a 5.32 TB/s bandwidth allows it to handle massive datasets that would be impossible for the Intel part. The 81.72 TFLOPS of FP32 performance is more than 17 times the Intel Arc Graphics 128EU Mobile's 4.608 TFLOPS, indicating a clear advantage in compute-heavy tasks such as scientific simulation, AI inference, and high-performance computing. The MI308X also has a texture rate of 2,553.6 GTexel/s, which is over 17 times higher than the Intel's 144.0 GTexel/s, reinforcing its dominance in tasks that rely on texture fetching and filtering.

The Intel Arc Graphics 128EU Mobile wins in the integrated graphics space for portable devices. Its 28 W TDP makes it suitable for thin-and-light laptops, whereas the MI308X requires 750 W and a suggested power supply of 1150 W. The Intel GPU has a pixel rate of 72.00 GPixel/s, which is a functional value, while the MI308X reports 0 MPixel/s, meaning the AMD accelerator does not handle traditional rasterization output. The Intel part supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, while the MI308X lists N/A for all three APIs. This makes the Intel Arc Graphics 128EU Mobile the only one of the two that can drive displays and run conventional graphics applications. Its boost clock of 2250 MHz is higher than the MI308X's 2100 MHz, though the AMD part has a higher base clock at 1000 MHz versus 300 MHz.

Architecture Differences

The AMD Instinct MI308X uses the CDNA 3.0 architecture, built on a 5 nm process at TSMC. The chip is named Aqua Vanjaram and belongs to the Instinct (MIx) generation. It contains 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4M per mm². The design is optimized for compute accelerators, with no raster output units and no display outputs. The MI308X is a PCIe 5.0 x16 card in an OAM Module slot format, and it has no power connectors, relying on the module's socket for power delivery.

The Intel Arc Graphics 128EU Mobile uses the Xe-LPG architecture, built on a 10 nm process at Intel. The chip is named Meteor Lake and belongs to the Arc Graphics-M (Meteor Lake) generation. No transistor count, die size, or transistor density is recorded for this part. It is an integrated GPU (IGP) with a Ring Bus interface, designed for portable devices. It has 32 raster output units, which allows it to produce a pixel rate of 72.00 GPixel/s, a feature entirely absent from the MI308X. The Intel part supports a full graphics API stack, including DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, while the MI308X has no API support listed.

The FP16 capabilities also differ structurally. The MI308X delivers FP16 at a 1:1 ratio with FP32, meaning both are 81.72 TFLOPS. The Intel Arc Graphics 128EU Mobile delivers FP16 at a 2:1 ratio, giving it 9.216 TFLOPS FP16 versus 4.608 TFLOPS FP32. This indicates that the AMD architecture treats FP16 as a first-class compute path, while the Intel architecture uses FP16 as a throughput-boosted mode.

Specification Differences

The two GPUs differ in nearly every measurable specification. The MI308X uses a 5 nm process at TSMC; the Intel part uses a 10 nm process at Intel. The MI308X has 153,000 million transistors on a 1017 mm² die; the Intel part has no recorded transistor count or die size. The MI308X has a base clock of 1000 MHz and a boost clock of 2100 MHz; the Intel part has a base clock of 300 MHz and a boost clock of 2250 MHz. The MI308X memory clock is 1300 MHz with 5.2 Gbps effective; the Intel part uses System Shared memory with no dedicated clock.

Memory capacity is 192 GB of HBM3 on an 8192-bit bus for the AMD part, versus System Shared for the Intel part. Bandwidth is 5.32 TB/s for the MI308X and System Dependent for the Intel. Shading units number 19,456 versus 1,024. Texture mapping units number 1,216 versus 64. Raster output units number 0 versus 32. Pixel rate is 0 MPixel/s versus 72.00 GPixel/s.

The MI308X was released on December 5, 2023; the Intel part was released on December 13, 2023. The Intel part is listed as Active in production; the AMD part has no production status listed. The MI308X's predecessor is Radeon Instinct; the Intel part's predecessor is HD Graphics-M.

Head-to-Head Benchmarks

The recorded benchmark data shows no direct head-to-head benchmark scores for these two GPUs, and neither has an average benchmark score or nearest rivals in the database. However, the specification differences provide a clear picture of relative performance in compute and graphics workloads.

The most significant win for the AMD Instinct MI308X is in FP32 throughput. At 81.72 TFLOPS, it delivers 17.7 times the FP32 performance of the Intel Arc Graphics 128EU Mobile's 4.608 TFLOPS. This is a direct mathematical comparison from the recorded data. In FP16, the MI308X again leads with 81.72 TFLOPS versus 9.216 TFLOPS, a factor of 8.9. The 1:1 FP16 ratio on the AMD part means there is no penalty for switching to half precision, whereas the Intel part doubles its FP32 rate to reach 9.216 TFLOPS.

Texture rate is another decisive win for the AMD part. The MI308X achieves 2,553.6 GTexel/s, which is 17.7 times the Intel's 144.0 GTexel/s. This indicates that the MI308X can process texture operations at a vastly higher rate, a critical metric for workloads that involve heavy filtering or sampling.

Memory bandwidth is also overwhelmingly in favor of the AMD accelerator. The MI308X provides 5.32 TB/s of bandwidth, while the Intel part's bandwidth is System Dependent, meaning it varies with the host system's memory configuration. The 192 GB capacity versus System Shared is another categorical difference; the MI308X can hold far more data on-device, reducing the need for transfers over the PCIe or Ring Bus interface.

The Intel Arc Graphics 128EU Mobile wins in pixel rate and API support. Its 72.00 GPixel/s is a functional rasterization rate, while the MI308X reports 0 MPixel/s. This means the Intel GPU can drive display outputs and run graphics APIs, while the MI308X has no display outputs and no supported graphics APIs. The Intel part also has a higher boost clock at 2250 MHz versus 2100 MHz, though the AMD part has a higher base clock at 1000 MHz versus 300 MHz.

In terms of power efficiency, the Intel part draws 28 W, which is 3.7% of the MI308X's 750 W TDP. While the MI308X delivers far more absolute performance, the Intel part achieves its 4.608 TFLOPS FP32 at a fraction of the power draw. The MI308X's suggested PSU of 1150 W highlights the system-level requirements, whereas the Intel integrated GPU requires no additional power supply guidance.

The process node difference also matters. The MI308X uses 5 nm at TSMC, while the Intel part uses 10 nm at Intel. The AMD part packs 150.4M transistors per mm², while the Intel part has no recorded density. The MI308X's die size of 1017 mm² is among the largest recorded in the database, while the Intel part's die size is not recorded.

The production status also differs. The Intel Arc Graphics 128EU Mobile is listed as Active, meaning it is currently in production. The AMD Instinct MI308X has no production status recorded, which may indicate a limited or discontinued run, though the database does not specify.

The release dates are close: December 5, 2023 for the MI308X and December 13, 2023 for the Intel part. Both are successors to earlier lines: the MI308X follows Radeon Instinct, and the Intel part follows HD Graphics-M.

The percentile ranking for both GPUs is 50 against all GPUs, and both have an average benchmark score of 0 in the database. This means neither has recorded benchmark results, so the head-to-head analysis rests entirely on the specification data. The wins are clear: the MI308X dominates compute throughput, memory capacity, bandwidth, and texture rate, while the Intel Arc Graphics 128EU Mobile dominates pixel rate, API compatibility, power efficiency, and form factor suitability for portable devices.
