AMD Radeon Instinct MI308X vs Intel Arc Graphics 2 Xe Mobile Comparison

Where Each One Wins

The AMD Radeon Instinct MI308X and Intel Arc Graphics 2 Xe Mobile occupy entirely different segments of the GPU spectrum, and the recorded data makes this split unmistakable. The MI308X is a data center accelerator built for massive parallel compute workloads, while the Arc Graphics 2 Xe Mobile is an integrated graphics solution aimed at portable devices. The benchmark database shows no direct head-to-head wins for either part, as their respective testing pools do not overlap, but the specification data reveals distinct domains of capability.

The MI308X delivers 81.72 TFLOPS of FP32 performance and 653.7 TFLOPS of FP16 performance with an 8:1 ratio, positioning it for dense compute tasks such as scientific simulation, AI training, and high-throughput data processing. Its 192 GB of HBM3 memory with a 10.3 TB/s bandwidth and 8192-bit bus width indicates a design optimized for memory-bound workloads where massive datasets must remain accessible to the compute units. The texture rate of 2,553.6 GTexel/s further underscores its raw throughput orientation.

The Intel Arc Graphics 2 Xe Mobile, by contrast, delivers 1,280.0 GFLOPS of FP32 performance and 2.560 TFLOPS of FP16 performance with a 2:1 ratio. Its 256 shading units, 16 TMUs, and 8 ROPs suggest a focus on efficient rendering for mobile form factors rather than extreme compute density. The 20.00 GPixel/s pixel rate and 40.00 GTexel/s texture rate are modest figures that align with integrated graphics expectations. The 2 ray tracing cores indicate some hardware-accelerated ray tracing capability, a feature absent from the MI308X's listed specifications.

The use-case split is therefore clear: the MI308X wins in any scenario requiring sustained, high-throughput compute on large data sets, while the Arc Graphics 2 Xe Mobile wins in scenarios requiring low power consumption, portability, and integrated display output. The MI308X has no display outputs, while the Arc Graphics 2 Xe Mobile's outputs are described as portable device dependent, reinforcing their different deployment targets.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two GPUs, and the wins count stands at zero for each. This absence itself is informative: the two products are so dissimilar in target application that no common benchmark suite produces comparable results. However, the recorded specification data allows for meaningful performance projections.

In FP32 compute, the MI308X's 81.72 TFLOPS dwarfs the Arc's 1,280.0 GFLOPS by a factor of roughly 64. In FP16, the MI308X's 653.7 TFLOPS (8:1) versus the Arc's 2.560 TFLOPS (2:1) represents an even larger gulf of approximately 255 times. The texture rate comparison shows the MI308X at 2,553.6 GTexel/s against the Arc's 40.00 GTexel/s, a 64-fold difference. The pixel rate comparison is closer in relative terms: the MI308X lists 0 MPixel/s due to its lack of ROPs, while the Arc delivers 20.00 GPixel/s, indicating the MI308X is not designed for traditional rasterization output.

Clock speeds tell a nuanced story. The Arc's boost clock of 2500 MHz exceeds the MI308X's 2100 MHz boost, but the MI308X's base clock of 1000 MHz is more than three times the Arc's 300 MHz base. The memory clock for the MI308X is 2525 MHz with 10.1 Gbps effective data rate, while the Arc's memory clock is system shared. These numbers reflect architectural priorities: the MI308X maintains high sustained clocks under load, while the Arc relies on boost behavior for burst performance.

The shading unit count difference is stark: 19,456 for the MI308X versus 256 for the Arc. The TMU count is 1,216 versus 16. These figures explain the massive throughput disparities without requiring direct benchmark comparisons. The MI308X's transistor density of 150.4M per mm² on a 1017 mm² die demonstrates a purpose-built compute chip, whereas the Arc's unknown transistor count and die size suggest a much smaller implementation.

Specification Differences

The two GPUs differ across nearly every recorded specification field. The MI308X is manufactured by AMD with the Aqua Vanjaram chip, while the Arc Graphics 2 Xe Mobile uses Intel's Wildcat Lake chip. The MI308X belongs to the Radeon Instinct (MIx) generation, and the Arc belongs to the Arc Graphics-M (Wildcat Lake) generation.

The MI308X has 153,000 million transistors on a 1017 mm² die, whereas the Arc's transistor count and die size are unknown. The MI308X has a transistor density of 150.4M per mm²; no density figure exists for the Arc.

Memory configurations are fundamentally different. The MI308X has 192 GB of HBM3 memory with an 8192-bit bus and 10.3 TB/s bandwidth. The Arc uses system shared memory with system dependent bandwidth. The MI308X's memory clock is 2525 MHz (10.1 Gbps effective), while the Arc's is system shared.

Compute resources differ by orders of magnitude: 19,456 shading units versus 256, 1,216 TMUs versus 16, 0 ROPs versus 8, and no listed ray tracing cores versus 2. The MI308X lists no API support, while the Arc supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Form factors and power profiles diverge completely. The MI308X is an OAM Module with no power connectors and a suggested PSU of 1150 W, while the Arc is an IGP with no power connectors and no suggested PSU. The MI308X has no display outputs; the Arc's outputs are portable device dependent. The bus interface is PCIe 5.0 x16 for the MI308X versus IGP for the Arc.

Release dates differ by over two years: the MI308X debuted on 2023-12-05, and the Arc is dated 2026-04-15 with a production status of active. Their predecessors also differ: FirePro Data Center for the MI308X, HD Graphics-M for the Arc.

Architecture Differences

The architectural divide between these two GPUs reflects their divergent design philosophies. The MI308X uses CDNA 3.0 architecture, which is AMD's compute-optimized design language focused on maximizing data throughput for data center workloads. The Arc Graphics 2 Xe Mobile uses Xe3-LPG architecture, Intel's low-power graphics architecture designed for integrated mobile solutions.

The MI308X's 5 nm TSMC process with 153,000 million transistors on a 1017 mm² die represents a massive, power-hungry compute chip. The Arc's 3 nm Intel process with unknown transistor count and die size indicates a smaller, more power-efficient design. The MI308X's transistor density of 150.4M per mm² shows how AMD packs compute units into available silicon, while the Arc's smaller footprint prioritizes integration into mobile platforms.

The MI308X has no listed ray tracing cores, while the Arc includes 2, suggesting Intel has integrated ray tracing support into its mobile architecture. The MI308X lists no API support, while the Arc supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, indicating its role as a rendering-focused part with modern graphics API compatibility.

The MI308X's FP16 ratio of 8:1 means it trades FP16 throughput for FP32 density, a common choice for data center accelerators that prioritize FP32 workloads. The Arc's FP16 ratio of 2:1 indicates a more balanced approach between FP16 and FP32, suitable for graphics and lighter compute tasks. The MI308X's texture rate of 2,553.6 GTexel/s versus the Arc's 40.00 GTexel/s demonstrates the compute-oriented versus rendering-oriented nature of each chip.

The MI308X's 0 MPixel/s pixel rate and 0 ROPs confirm it does not perform traditional rasterization, while the Arc's 20.00 GPixel/s and 8 ROPs show it does. The MI308X's lack of display outputs further confirms its role as a compute accelerator without visual output. The Arc's portable device dependent outputs show its integration into mobile systems where display connectivity varies by platform.

The Verdict

The data indicates that these GPUs are not competitors but rather complementary solutions for entirely different computing environments. The AMD Radeon Instinct MI308X is a data center accelerator with 81.72 TFLOPS FP32, 653.7 TFLOPS FP16, 192 GB of HBM3 memory, and 10.3 TB/s bandwidth. It operates at 750 W TDP with a 1150 W suggested PSU and exists as an OAM Module. Its 19,456 shading units and 1,216 TMUs process data at 2,553.6 GTexel/s. This part targets users who need extreme compute throughput for large-scale data processing, AI training, or scientific workloads where memory capacity and bandwidth are critical constraints.

The Intel Arc Graphics 2 Xe Mobile is an integrated GPU with 256 shading units, 16 TMUs, 8 ROPs, and 2 ray tracing cores. It delivers 1,280.0 GFLOPS FP32 and 2.560 TFLOPS FP16 at 25 W TDP. Its 2500 MHz boost clock exceeds the MI308X's 2100 MHz boost, but its 300 MHz base clock is far lower. It uses system shared memory and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. This part targets portable devices where power efficiency, small footprint, and integrated rendering capability matter more than raw compute throughput.

The percentile data places both at the 50th percentile versus all GPUs, but this similarity is misleading given their divergent roles. The MI308X's advantages in FP32, FP16, memory capacity, bandwidth, texture rate, and shading unit count make it the clear choice for compute-heavy data center workloads. The Arc's advantages in process node efficiency, ray tracing support, API compatibility, and display output capability make it the clear choice for mobile integrated graphics. Neither part can substitute for the other in its intended environment. The MI308X cannot output video, and the Arc cannot approach the compute density required for large-scale parallel processing. The recorded data shows two specialized tools serving distinct niches, with no meaningful overlap in their performance envelopes or target applications.
