AMD Instinct MI308X vs Intel Arc Graphics 4 Xe Mobile Comparison

Where Each One Wins

The recorded data shows a stark division of roles between these two processors. The AMD Instinct MI308X is a compute accelerator with no display outputs, no graphics API support, and zero ROPs. Its entire design centers on raw mathematical throughput. The Intel Arc Graphics 4 Xe Mobile is an integrated graphics processor built for rendering and display. The benchmark database contains no direct head-to-head benchmark results for these two parts, so the wins are defined by architectural capability rather than measured scores.

The AMD Instinct MI308X wins exclusively in compute-heavy workloads. It delivers 81.72 TFLOPS of FP32 performance and the same 81.72 TFLOPS in FP16 with a 1:1 ratio. The texture rate reaches 2,553.6 GTexel/s. These figures indicate a device designed for dense matrix operations, scientific simulation, and large-scale data processing. The 192 GB HBM3 memory with 5.32 TB/s bandwidth and an 8192-bit bus width positions it for datasets that would overwhelm any integrated solution.

The Intel Arc Graphics 4 Xe Mobile wins in every scenario that involves displaying an image. It has 16 ROPs producing 36.80 GPixel/s, four ray tracing cores, and support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The 512 shading units and 32 TMUs deliver 73.60 GTexel/s and 2.355 TFLOPS FP32. Its FP16 throughput doubles to 4.710 TFLOPS with a 2:1 ratio, which suits graphics shader workloads. The IGP form factor with system-shared memory means it can drive portable device displays.

The AMD part has no pixel rate (0 MPixel/s) and no ROPs, which means it cannot rasterize frames. The Intel part has a modest 25 W TDP and operates as an integrated solution, which means it fits in mobile devices. The data confirms these are not competitors; they are complementary tools for different tasks.

Architecture Differences

The AMD Instinct MI308X uses the CDNA 3.0 architecture on the Aqua Vanjaram chip. It is built on a 5 nm process at TSMC with 153,000 million transistors on a 1017 mm² die. The transistor density is 150.4M per mm². The base clock is 1000 MHz with a boost clock of 2100 MHz. Memory clocks run at 1300 MHz with 5.2 Gbps effective. The chip uses HBM3 memory with 192 GB capacity, an 8192-bit bus, and 5.32 TB/s bandwidth.

The Intel Arc Graphics 4 Xe Mobile uses the Xe3-LPG architecture on the Panther Lake chip. It is built on a 3 nm process at Intel. The transistor count and die size are listed as unknown. The base clock is 300 MHz with a boost clock of 2300 MHz. Memory is system-shared, meaning the bus width, type, and bandwidth are all system dependent. The IGP has no dedicated memory interface.

The AMD chip has 19,456 shading units and 1,216 TMUs but zero ROPs. It has no ray tracing cores and no tensor cores listed. The Intel chip has 512 shading units, 32 TMUs, 16 ROPs, and 4 ray tracing cores. The AMD chip has no API support for DirectX, OpenGL, or Vulkan. The Intel chip supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The AMD part uses a PCIe 5.0 x16 bus interface and an OAM module slot width. It has no power connectors and no display outputs. The suggested PSU is 1150 W. The Intel part uses an IGP bus interface and slot width, has no power connectors, and its display outputs depend on the portable device. Its TDP is 25 W.

The AMD part was released on 2023-12-05, while the Intel part has a release date of 2026-01-26 and an active production status. The AMD part lists a predecessor of Radeon Instinct. The Intel part has no predecessor listed.

The Verdict

The data shows that the AMD Instinct MI308X and Intel Arc Graphics 4 Xe Mobile serve entirely different purposes. The MI308X is a compute accelerator with no graphics output capability. The Arc Graphics 4 Xe Mobile is an integrated graphics processor with no compute acceleration role beyond standard GPU tasks.

For workloads requiring massive parallel computation, the MI308X delivers 81.72 TFLOPS FP32, 192 GB of HBM3 memory, and 5.32 TB/s bandwidth. These figures are orders of magnitude beyond the Intel part's 2.355 TFLOPS FP32 and system-shared memory. The MI308X also has a 750 W TDP, which indicates a server or workstation context. Its PCIe 5.0 x16 interface and OAM module form factor confirm this.

For rendering, rasterization, and display output, the Arc Graphics 4 Xe Mobile is the only viable choice. It has 16 ROPs, 4 ray tracing cores, and full graphics API support. Its 25 W TDP and IGP form factor make it suitable for mobile devices. The MI308X cannot display anything, so any use case involving visual output falls to the Intel part.

The benchmark database shows no head-to-head results, and the percentile rankings are both 50. This indicates the database has not measured either part in comparable workloads. The architectural differences are so fundamental that a direct comparison would be meaningless. The MI308X is for compute servers. The Arc Graphics 4 Xe Mobile is for mobile graphics. The verdict from the data is clear: choose based on the task, not the performance tier.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results between these two processors. The winsA and winsB fields are both zero. This absence of measured data is itself informative: the two parts occupy such different segments that no common benchmark has been run.

Instead, the comparison rests on specification-level differences. The FP32 compute difference is substantial. The MI308X delivers 81.72 TFLOPS, which is 34.7 times the Arc Graphics 4 Xe Mobile's 2.355 TFLOPS. The FP16 comparison is also stark: the MI308X offers 81.72 TFLOPS at 1:1 ratio, while the Intel part offers 4.710 TFLOPS at 2:1 ratio. The MI308X leads by a factor of 17.3 in FP16.

Texture throughput follows a similar pattern. The MI308X reaches 2,553.6 GTexel/s compared to 73.60 GTexel/s for the Arc Graphics 4 Xe Mobile. That is a 34.7x advantage in texture rate. The pixel rate tells the opposite story. The MI308X has 0 MPixel/s, while the Intel part delivers 36.80 GPixel/s. The Intel part is the only one capable of rasterizing pixels.

Memory bandwidth shows the largest absolute gap. The MI308X has 5.32 TB/s from HBM3 over an 8192-bit bus. The Arc Graphics 4 Xe Mobile has system-dependent bandwidth, which means it shares memory with the host processor. The MI308X also has 192 GB of dedicated memory, while the Intel part has no dedicated graphics memory.

Clock speeds differ in both base and boost. The MI308X runs at 1000 MHz base and 2100 MHz boost. The Arc Graphics 4 Xe Mobile runs at 300 MHz base and 2300 MHz boost. The Intel part has a higher boost clock but a much lower base clock. The MI308X has a higher base clock with a lower boost ceiling.

Shader resources reinforce the compute divide. The MI308X has 19,456 shading units and 1,216 TMUs. The Arc Graphics 4 Xe Mobile has 512 shading units and 32 TMUs. The MI308X has 38 times more shading units and 38 times more TMUs. The Intel part counters with 16 ROPs and 4 ray tracing cores, neither of which the MI308X has.

Transistor counts are only available for the AMD part: 153,000 million on a 1017 mm² die. The Intel part's transistor count and die size are unknown. The process nodes differ, with the MI308X at 5 nm TSMC and the Arc Graphics 4 Xe Mobile at 3 nm Intel. The MI308X has a larger die on an older node. The Intel part uses a newer node but has no listed transistor density.
