AMD Instinct MI308X vs Intel Arc Graphics 48EU Mobile Comparison

The database compares the AMD Instinct MI308X and the Intel Arc Graphics 48EU Mobile as two GPU-class parts with no recorded head-to-head benchmark entries. The AMD side is a CDNA 3.0 accelerator built on the Aqua Vanjaram chip at TSMC's 5 nm process, with 192 GB HBM3 and 81.72 TFLOPS FP32. The Intel side is an Xe-LPG integrated GPU built on the Meteor Lake chip at Intel's 10 nm process, with 384 shading units and system-shared memory. Both entries sit at the 50th percentile in the all-GPU distribution, and both have an average benchmark score of 0, so the comparison that follows is based on the recorded specification data rather than measured benchmark results.

Head-to-Head Benchmarks

The head-to-head benchmark list in the database is empty. The recorded win tally is 0 for the AMD Instinct MI308X and 0 for the Intel Arc Graphics 48EU Mobile. There are therefore no measured percentage deltas from nearest rivals to report. What the database does record is a set of specification deltas that define the largest gaps between the two parts.

In FP32 throughput, the AMD part delivers 81.72 TFLOPS while the Intel part delivers 1,382.4 GFLOPS. In texture rate, the AMD part delivers 2,553.6 GTexel/s while the Intel part delivers 43.20 GTexel/s. In memory bandwidth, the AMD part delivers 5.32 TB/s over an 8192 bit HBM3 bus, while the Intel part reports System Dependent bandwidth over System Shared memory.

The Intel part holds the advantage in pixel rate, with 14.40 GPixel/s versus 0 MPixel/s for the AMD part. The AMD part also lists an FP16 figure of 81.72 TFLOPS (1:1), whereas the Intel part lists 2.765 TFLOPS (2:1). These are the largest recorded wins in each direction, though they are specification wins rather than benchmark wins.

Architecture Differences

Architecture separates the two parts completely. The AMD Instinct MI308X uses the CDNA 3.0 architecture with the Aqua Vanjaram chip, built by TSMC on a 5 nm process. The Intel Arc Graphics 48EU Mobile uses the Xe-LPG architecture with the Meteor Lake chip, built by Intel on a 10 nm process. The AMD part records 153,000 million transistors on a 1017 mm² die, for a transistor density of 150.4M / mm². The Intel part does not have recorded transistor count, die size, or transistor density in the database.

Memory architecture is another major split. The AMD part uses 192 GB HBM3 on an 8192 bit bus, with 5.32 TB/s bandwidth and a memory clock of 1300 MHz (5.2 Gbps effective). The Intel part uses System Shared memory with System Shared type and bus width, and System Dependent bandwidth; its memory clock is also System Shared.

Compute resources differ substantially in shading units: 19,456 on the AMD part versus 384 on the Intel part. The AMD part has 1,216 texture mapping units and 0 ROPs, while the Intel part has 24 texture mapping units and 8 ROPs. The resulting pixel rates are 0 MPixel/s for AMD and 14.40 GPixel/s for Intel; resulting texture rates are 2,553.6 GTexel/s for AMD and 43.20 GTexel/s for Intel. Clocks also differ: the AMD part runs at a 1000 MHz base and 2100 MHz boost, while the Intel part runs at a 300 MHz base and 1800 MHz boost.

Feature support differs at the API level. The AMD part records DirectX, OpenGL, and Vulkan as N/A. The Intel part records DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4.

Power and integration approach differ sharply. The AMD part is an OAM Module with a 750 W TDP, a suggested PSU of 1150 W, no power connectors, and a PCIe 5.0 x16 bus interface. The Intel part is an IGP with a 28 W TDP, a Ring Bus interface, and no recorded suggested PSU. The AMD part has no display outputs; the Intel part has display outputs described as Portable Device Dependent. The AMD part's production status is not recorded, while the Intel part is Active. The AMD predecessor is Radeon Instinct, and the Intel predecessor is HD Graphics-M. Release dates are 2023-12-05 for the AMD part and 2023-12-13 for the Intel part.

Where Each One Wins

Given the absence of benchmark scores, the win split is based on recorded specifications. The AMD Instinct MI308X wins the FP32 comparison with 81.72 TFLOPS, the FP16 comparison with 81.72 TFLOPS (1:1), the texture rate comparison with 2,553.6 GTexel/s, the memory capacity comparison with 192 GB, the memory bus width comparison with 8192 bit, and the memory bandwidth comparison with 5.32 TB/s. The OAM Module slot width, PCIe 5.0 x16 interface, 750 W TDP, and suggested 1150 W PSU all point to a module built for raw compute throughput with no display outputs.

The Intel Arc Graphics 48EU Mobile wins the pixel-rate comparison with 14.40 GPixel/s versus 0 MPixel/s, the API support comparison with DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, and the integration comparison with a 28 W TDP, IGP slot width, Ring Bus interface, and Portable Device Dependent display outputs. The Intel part's 8 ROPs versus 0 ROPs explains its pixel-rate advantage, while the AMD part's 1,216 TMUs versus 24 TMUs explains its texture-rate advantage. The Intel part also has an Active production status, while the AMD part's production status is not recorded.
