AMD Instinct MI300X vs Intel Arc Graphics 2 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Instinct MI300X and the Intel Arc Graphics 2 Xe Mobile covers fundamentally different segments, and direct comparisons must rely on the available benchmark metrics. The database contains a single Geekbench OpenCL result for the AMD Instinct MI300X, scoring 317,994 points. This places the Instinct MI300X at the 100th percentile among all GPUs in the database, meaning it outperforms every other recorded graphics processor in this specific metric. The Intel Arc Graphics 2 Xe Mobile, however, has no recorded benchmark entries in the database at this time, giving it an average benchmark score of zero and a percentile ranking of 50.

Because no head-to-head benchmark results exist between these two parts, a direct numerical score comparison cannot be produced from the data. The only quantitative insight available is the absolute score of the AMD part and its relative standing against its nearest rivals. The Instinct MI300X trails the NVIDIA B200 by 8% and the NVIDIA H200 NVL by 5%, based on their respective average scores of 345,482 and 334,891. It leads the NVIDIA L40S by 7.5% and the NVIDIA RTX 6000 Ada Generation by 10.7%. The Intel Arc Graphics 2 Xe Mobile, with no recorded scores, cannot be positioned in any such ranking. The data confirms that the AMD accelerator delivers a score of 317,994, while the Intel integrated solution has no measurable benchmark result to report.

Architecture Differences

The two processors originate from different manufacturers, foundries, and design philosophies. The AMD Instinct MI300X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, fabricated on a 5 nm process at TSMC. It contains 153,000 million transistors on a die size of 1017 mm², yielding a transistor density of 150.4 million transistors per square millimeter. The Intel Arc Graphics 2 Xe Mobile uses the Wildcat Lake chip on Xe3-LPG architecture, fabricated on Intel's own 3 nm process. Its transistor count and die size are not recorded in the database.

Core configurations differ drastically. The AMD part features 19,456 shading units, 1,216 texture mapping units, and no ROPs, resulting in a pixel rate of 0 MPixel/s and a texture rate of 2,553.6 GTexel/s. The Intel part features 256 shading units, 16 TMUs, 8 ROPs, and 2 ray tracing cores, delivering a pixel rate of 20.00 GPixel/s and a texture rate of 40.00 GTexel/s. The AMD accelerator has no ray tracing cores listed, while the Intel integrated GPU includes dedicated ray tracing hardware.

Memory architecture is another clear divider. The Instinct MI300X uses 192 GB of HBM3 memory across an 8192-bit bus, delivering 5.32 TB/s of bandwidth, with memory clocked at 1300 MHz or 5.2 Gbps effective. The Intel part uses system shared memory, with the type, bus width, and bandwidth all designated as system dependent. Clock behavior also differs: the AMD chip runs at 1000 MHz base and 2100 MHz boost, while the Intel chip runs at 300 MHz base and 2500 MHz boost.

Compute throughput separates the two by orders of magnitude. The AMD Instinct MI300X delivers 81.72 TFLOPS of FP32 and 81.72 TFLOPS of FP16 at a 1:1 ratio. The Intel Arc Graphics 2 Xe Mobile delivers 1,280.0 GFLOPS of FP32 and 2.560 TFLOPS of FP16 at a 2:1 ratio. Power consumption reflects this gap: the AMD module is rated at 750 W TDP and requires a suggested power supply of 1150 W, while the Intel IGP is rated at 25 W with no suggested PSU recorded. The AMD part uses a PCIe 5.0 x16 interface and is an OAM module, while the Intel part is an IGP with no dedicated bus interface beyond the integrated graphics path.

API support further distinguishes them. The Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD accelerator lists no supported graphics APIs, with DirectX, OpenGL, and Vulkan all marked as not applicable. Display outputs also differ: the AMD module has no outputs, while the Intel part's outputs are listed as portable device dependent. Release dates recorded in the database place the AMD Instinct MI300X in December 2023 and the Intel Arc Graphics 2 Xe Mobile in April 2026. The Intel part is listed as active in production, while the AMD part's production status is not recorded.

Where Each One Wins

The AMD Instinct MI300X wins in raw compute throughput, memory capacity, and memory bandwidth. Its 192 GB of HBM3 memory with 5.32 TB/s bandwidth is unmatched by any integrated solution, and its 81.72 TFLOPS FP32 output reflects a design aimed at massive parallel workloads. The data shows it ranks at the 100th percentile among all GPUs in the database, ahead of several high-end NVIDIA accelerators in the Geekbench OpenCL metric. The Intel Arc Graphics 2 Xe Mobile cannot compete in these categories, as it relies on system shared memory and delivers 1,280.0 GFLOPS of FP32, roughly 64 times less raw floating-point throughput when comparing the recorded figures.

The Intel Arc Graphics 2 Xe Mobile wins in areas relevant to client systems. Its 25 W TDP makes it suitable for power-constrained mobile platforms, whereas the AMD module consumes 750 W and requires a 1150 W power supply. The Intel part includes 2 ray tracing cores and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it applicable to graphics rendering workloads that require modern graphics APIs. The AMD part has no graphics API support recorded and no display outputs, confirming its role as a compute accelerator rather than a display adapter. The Intel part's pixel rate of 20.00 GPixel/s and texture rate of 40.00 GTexel/s, while modest, indicate an actual rasterization capability, whereas the AMD part's 0 MPixel/s pixel rate reflects its lack of traditional graphics output functionality.

Clock speed behavior also favors the Intel part in terms of boost frequency. The Intel chip boosts to 2500 MHz, above the AMD chip's 2100 MHz boost. However, the AMD part's 1000 MHz base clock is over three times higher than the Intel part's 300 MHz base clock, indicating different operating points for different thermal and power envelopes. The Intel part's production status is active, while no production status is recorded for the AMD part, which may indicate differences in availability, though the database does not specify this further.

The Verdict

The data positions the AMD Instinct MI300X as a high-end compute accelerator with no display output, no graphics API support, and a 750 W power envelope. Its benchmark score of 317,994 ranks it at the 100th percentile, with its nearest rivals being the NVIDIA B200, H200 NVL, L40S, and RTX 6000 Ada Generation. The Instinct MI300X sits between the B200 and H200 NVL in score, trailing both by 8% and 5% respectively, while leading the L40S by 7.5% and the RTX 6000 Ada by 10.7%. This makes it a competitive option in the accelerator segment, though not the top scorer in the database.

The Intel Arc Graphics 2 Xe Mobile, by contrast, is an integrated processor with ray tracing cores, modern graphics API support, and a 25 W TDP. It has no recorded benchmark scores and no rivals listed in the database. Its 256 shading units, 16 TMUs, and 8 ROPs place it in an entirely different performance class from the AMD part. The data does not support any claim of equivalence between them; they serve different market segments entirely. The AMD part is for compute-heavy workloads requiring massive memory and bandwidth, while the Intel part is for mobile graphics with API compatibility and low power draw. A user selecting between these two would be choosing between a server-class accelerator and an integrated mobile GPU, a distinction the recorded specifications make unambiguous.
