AMD Radeon Instinct MI300A vs Intel Arc Graphics 4 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Radeon Instinct MI300A and the Intel Arc Graphics 4 Xe Mobile shows no benchmark results in the database. Neither product has any entries in the head-to-head benchmark table, and both carry an identical percentile ranking of 50 against all GPUs. Their average benchmark scores are both listed as zero, meaning no performance measurements have been recorded for either device in this dataset.

The absence of benchmark scores is itself informative. The AMD Radeon Instinct MI300A is a data center compute accelerator with a 750 W TDP, designed for high-throughput workloads. The Intel Arc Graphics 4 Xe Mobile is a 25 W integrated graphics processor intended for portable devices. These are fundamentally different product categories, and the database currently holds no comparative benchmark data between them.

Without recorded benchmark scores, the wins column shows zero for both products. The head-to-head comparison table is empty. This indicates that any performance assessment must be derived from architectural specifications and theoretical compute figures rather than measured application performance.

Architecture Differences

The AMD Radeon Instinct MI300A uses the CDNA 3.0 architecture on a 5 nm TSMC process. The chip, codenamed Aqua Vanjaram, integrates 153,000 million transistors across a 1017 mm² die, yielding a transistor density of 150.4M per mm². The Intel Arc Graphics 4 Xe Mobile uses the Xe3-LPG architecture on Intel's 3 nm process. The chip is codenamed Panther Lake, and its transistor count and die size are listed as unknown in the database.

The MI300A deploys 19,456 shading units, 1,216 texture mapping units, and zero ROPs. Its pixel rate is 0 MPixel/s, while its texture rate reaches 2,553.6 GTexel/s. The Intel part uses 512 shading units, 32 TMUs, and 16 ROPs, with a pixel rate of 36.80 GPixel/s and a texture rate of 73.60 GTexel/s. The Intel GPU includes 4 ray tracing cores, while the AMD accelerator lists no ray tracing cores. Neither product lists tensor cores in the database.

The compute figures diverge sharply. The MI300A delivers 81.72 TFLOPS of FP32 performance and 653.7 TFLOPS of FP16 performance using an 8:1 ratio. The Intel Arc Graphics 4 Xe Mobile produces 2.355 TFLOPS of FP32 and 4.710 TFLOPS of FP16 with a 2:1 ratio. The MI300A's FP32 throughput is roughly 34.7 times higher based on these figures, though no specific percentage delta is recorded in the database.

Clock behavior also differs. The AMD part has a base clock of 1000 MHz and a boost clock of 2100 MHz. The Intel part runs at a 300 MHz base and 2300 MHz boost. The Intel GPU actually boosts higher, but this is offset by its much smaller execution resource pool.

Memory architecture separates the two entirely. The MI300A carries 192 GB of HBM3 memory on an 8192-bit bus, delivering 10.3 TB/s of bandwidth. Memory clock operates at 2525 MHz with 10.1 Gbps effective speed. The Intel Arc Graphics 4 Xe Mobile uses system-shared memory with a system-dependent bus width and bandwidth. There is no dedicated VRAM.

The MI300A uses a PCIe 5.0 x16 bus interface and an OAM Module slot width. It has no display outputs. The Intel part uses an IGP bus interface, also has no power connectors, and its display outputs are portable device dependent.

In terms of API support, the Intel GPU explicitly lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD accelerator lists null values for all three APIs in the database. This reflects the MI300A's role as a compute-focused accelerator rather than a graphics rendering device.

Power consumption differs by an order of magnitude. The MI300A has a TDP of 750 W with a suggested PSU of 1150 W. The Intel part has a 25 W TDP and no suggested PSU listed. Both use no external power connectors, with the AMD module relying on the OAM socket and the Intel IGP drawing from the host platform.

Release dates are separated by roughly two years. The MI300A launched on 2023-12-05, while the Intel part is dated 2026-01-26. The AMD product's predecessor is listed as FirePro Data Center, while the Intel part has no predecessor recorded. Production status for the MI300A is not specified in the database, while the Intel part is marked as Active.

The Verdict

The data shows two products engineered for entirely different deployment scenarios. The AMD Radeon Instinct MI300A is a data center accelerator with 19,456 shading units, 192 GB of HBM3 memory, and 81.72 TFLOPS of FP32 compute. Its 750 W TDP and OAM Module form factor place it in server racks, not consumer systems. The Intel Arc Graphics 4 Xe Mobile is an integrated GPU for portable devices, drawing only 25 W and sharing system memory.

For compute-heavy workloads such as large-scale matrix operations, the MI300A's 653.7 TFLOPS of FP16 throughput and 10.3 TB/s memory bandwidth put it in a different performance class. The Intel part's 4.710 TFLOPS of FP16 and system-dependent bandwidth target efficiency rather than peak throughput.

For graphics rendering in mobile form factors, the Intel part has the advantage of 4 ray tracing cores, 16 ROPs, and full API support including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The MI300A lists no display outputs and no graphics APIs, confirming its compute-only orientation.

The process node difference favors Intel at 3 nm versus AMD's 5 nm, though the MI300A's larger die and transistor count of 153,000 million reflect a much more complex chip. The Intel part's transistor count remains unknown in the database.

The release timing shows the Intel product arriving later, dated 2026-01-26, while the AMD product shipped on 2023-12-05. The AMD product's predecessor is FirePro Data Center, while the Intel part has no recorded predecessor.

The database currently holds no benchmark scores for either product, so the verdict rests on the architectural specifications. The MI300A is built for maximum compute density with 2,553.6 GTexel/s texture rate and 81.72 TFLOPS FP32. The Intel Arc Graphics 4 Xe Mobile is built for integrated efficiency with 36.80 GPixel/s pixel rate and 25 W power draw. Each product serves a distinct market segment, and the data confirms they are not direct competitors. The MI300A suits data center compute tasks where power and size are secondary to throughput. The Intel part suits mobile devices where power efficiency and integrated graphics capability are primary constraints.
