AMD Instinct MI300X vs Intel Arc Graphics 4 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison situation. The AMD Instinct MI300X has one benchmark entry, a Geekbench OpenCL score of 317,994, while the Intel Arc Graphics 4 Xe Mobile has no recorded benchmark scores in the database. This means the head-to-head benchmark field is empty, with zero wins recorded for each side. However, the MI300X's absolute score can still be interpreted through its nearest rival data, which provides a meaningful performance context.

The MI300X's OpenCL score of 317,994 places it in the 100th percentile of all GPUs in the database. This is a strong indicator of top-tier compute performance. Its nearest rivals show a tight competitive cluster. The NVIDIA H200 NVL posts an average score of 334,891, which is 5% higher than the MI300X. The NVIDIA B200 reaches 345,482, an 8% advantage. Conversely, the MI300X sits 7.5% ahead of the NVIDIA L40S, which scores 295,763, and 10.7% ahead of the NVIDIA RTX 6000 Ada Generation, which scores 287,237.

The data suggests the MI300X is squarely within the high-end accelerator tier, trading blows with the most powerful NVIDIA data center parts. The 5% and 8% deficits to the H200 NVL and B200 respectively are relatively small margins in this performance class. The larger leads over the L40S and RTX 6000 Ada Generation, 7.5% and 10.7%, indicate that the MI300X holds a clear advantage over the previous generation of professional workstation GPUs.

For the Intel Arc Graphics 4 Xe Mobile, the absence of benchmark data means no direct performance assertions can be made from measurements. The database records its percentile as 50, which is the median position, but with zero average score. This is a data gap, not a performance verdict. The comparison here is fundamentally asymmetric: one product has a measured score and rival context, the other has no measured performance at all.

The implication is that the MI300X is a compute accelerator designed for maximum throughput, while the Intel part is an integrated mobile GPU whose performance is not yet characterized in the database. Any direct head-to-head speculation would require data that does not exist in the record.

The Verdict

Based strictly on the available data, the verdict is clear for the AMD Instinct MI300X: it is a high-performance accelerator with a measured OpenCL score of 317,994, sitting in the 100th percentile of all recorded GPUs. Its nearest rival comparisons show it is competitive with, though slightly behind, the top NVIDIA H200 NVL and B200 parts, while clearly ahead of the L40S and RTX 6000 Ada Generation. Users requiring massive compute throughput for workloads that scale with FP32 or FP16 operations would find this product at the top of the measured hierarchy.

The Intel Arc Graphics 4 Xe Mobile has no recorded benchmark scores, so no performance verdict can be issued from measurements. Its 50th percentile ranking is a placeholder, not a result. The data shows it is an integrated graphics processor with a 25 W TDP, which suggests a fundamentally different use case: low-power, portable systems integrated into a processor package. Without benchmark data, the database cannot confirm its relative standing among mobile GPUs.

The data does not support a direct choice between these two products. They occupy different segments: one is a discrete accelerator module with 750 W TDP and no display outputs, the other is an IGP with portable device dependent outputs and a 25 W TDP. Any user selecting between them would be choosing between a server compute accelerator and a mobile integrated GPU, which are not competing products in the same market. The MI300X is validated by its measured performance and rival comparisons; the Intel part awaits benchmark characterization.

Architecture Differences

The architectural divide between these two products is substantial. The AMD Instinct MI300X uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, built on a 5 nm process at TSMC. The Intel Arc Graphics 4 Xe Mobile uses the Xe3-LPG architecture on the Panther Lake chip, built on a 3 nm process at Intel. These are entirely different design philosophies: CDNA 3.0 targets massive parallel compute, while Xe3-LPG targets efficiency and integration.

The MI300X contains 153,000 million transistors on a die size of 1017 mm², yielding a transistor density of 150.4M per mm². The Intel part has unknown transistor count and die size, a notable gap in the recorded data. The MI300X's transistor budget is enormous, enabling 19,456 shading units, 1,216 texture mapping units, and 0 ROPs. The Intel part has 512 shading units, 32 TMUs, 16 ROPs, and 4 ray tracing cores. The MI300X has no RT cores recorded, while the Intel part includes hardware ray tracing support.

Memory architecture differs fundamentally. The MI300X uses 192 GB of HBM3 across an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The Intel Arc Graphics 4 Xe Mobile uses system shared memory, with shared type, bus width, and system-dependent bandwidth. This means the MI300X has dedicated high-bandwidth memory, while the Intel part relies on the host system's memory subsystem.

Clock behavior also diverges. The MI300X has a base clock of 1000 MHz and a boost of 2100 MHz, with memory at 1300 MHz (5.2 Gbps effective). The Intel part has a 300 MHz base and 2300 MHz boost, with system shared memory clock. The MI300X's FP32 throughput is 81.72 TFLOPS with FP16 at 81.72 TFLOPS (1:1 ratio), while the Intel part delivers 2.355 TFLOPS FP32 and 4.710 TFLOPS FP16 (2:1 ratio). The API support also differs: the MI300X has no DirectX, OpenGL, or Vulkan support recorded, while the Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The process node difference (5 nm TSMC vs 3 nm Intel) is relevant, but the Intel part's unknown transistor count prevents a density comparison. The MI300X's 750 W TDP versus the Intel's 25 W TDP highlights the extreme range in power envelopes, but the architectural contrast is most evident in the shading unit count: 19,456 versus 512, a 38x difference that directly explains the TFLOPS disparity.
