AMD Radeon Instinct MI300A vs Intel Arc Graphics 2 Xe Mobile Comparison

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for this pairing. Both the AMD Radeon Instinct MI300A and the Intel Arc Graphics 2 Xe Mobile have an average benchmark score of zero and a percentile rank of 50 among all GPUs. This means there are no recorded measurements that directly compare their performance in any workload. The absence of data is itself informative: these two parts occupy entirely different segments of the graphics hardware spectrum, and no standardized test in the database has been run on both.

The AMD Radeon Instinct MI300A is a data center accelerator with a peak FP32 throughput of 81.72 TFLOPS. The Intel Arc Graphics 2 Xe Mobile delivers 1,280.0 GFLOPS in FP32, which converts to 1.28 TFLOPS. The ratio is approximately 64 to 1 in raw shader throughput. Texture rate tells a similar story: the MI300A reaches 2,553.6 GTexel/s while the Intel part manages 40.00 GTexel/s. Pixel rate is the one metric where the Intel part is not zero: it outputs 20.00 GPixel/s, while the AMD accelerator has a pixel rate of 0 MPixel/s because it has no ROPs and no display outputs.

The FP16 comparison shows a different architectural emphasis. The MI300A delivers 653.7 TFLOPS in FP16 at an 8:1 ratio relative to FP32, indicating heavy use of packed math for AI workloads. The Intel part delivers 2.560 TFLOPS in FP16 at a 2:1 ratio, which is a more conventional consumer-oriented configuration. The 8:1 ratio on the AMD part means it trades FP32 throughput for FP16 throughput at a much higher multiplier, consistent with a compute-optimized design.

Where Each One Wins

The AMD Radeon Instinct MI300A wins in every metric where the two can be numerically compared, except pixel rate. Its advantages are concentrated in raw compute, memory bandwidth, and memory capacity. The MI300A has 192 GB of HBM3 memory with a bandwidth of 10.3 TB/s on an 8192-bit bus. The Intel Arc Graphics 2 Xe Mobile uses System Shared memory with System Dependent bandwidth, which means its memory performance is entirely determined by the host platform. There is no fixed bandwidth figure in the database for the Intel part, so direct comparison is not possible, but the architectural difference is clear: one part has dedicated high-bandwidth memory, the other relies on shared system memory.

The Intel Arc Graphics 2 Xe Mobile wins in the categories of power efficiency and integration. Its TDP is 25 W, compared to 750 W for the AMD accelerator. The Intel part is classified as an IGP with no power connectors, while the AMD part is an OAM Module with no power connectors but a suggested PSU of 1150 W. The Intel part is also the only one of the two with a production status of Active. The AMD part has no production status listed. For any workload that requires a portable or low-power device, the Intel part is the only viable option. The AMD part is not designed for such environments at all.

The Intel part also wins on API support. It lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part has null values for DirectX, OpenGL, and Vulkan, which indicates it is not intended for graphics API workloads. Display outputs are listed as "No outputs" for the AMD part and "Portable Device Dependent" for the Intel part, reinforcing that the Intel part is meant to drive displays while the AMD part is not.

Specification Differences

The two parts differ in nearly every specification field. The AMD Radeon Instinct MI300A uses the Aqua Vanjaram chip with CDNA 3.0 architecture, while the Intel Arc Graphics 2 Xe Mobile uses the Wildcat Lake chip with Xe3-LPG architecture. The AMD part is built on a 5 nm process at TSMC with 153,000 million transistors on a 1017 mm² die. The Intel part is built on a 3 nm process at Intel with unknown transistor count and die size.

Clock speeds differ substantially. The AMD part has a base clock of 1000 MHz and a boost clock of 2100 MHz. The Intel part has a base clock of 300 MHz and a boost clock of 2500 MHz. Memory clocks are 2525 MHz (10.1 Gbps effective) for the AMD part, while the Intel part lists "System Shared" for memory clock.

The shading unit count is 19,456 for the AMD part versus 256 for the Intel part. TMUs are 1,216 versus 16. ROPs are 0 for the AMD part and 8 for the Intel part. The AMD part has no ROPs because it is not designed for rasterization. The Intel part has 2 ray tracing cores, while the AMD part has none listed.

The AMD part has a TDP of 750 W, slot width of OAM Module, and no power connectors. The Intel part has a TDP of 25 W, slot width of IGP, and no power connectors. The AMD part has a suggested PSU of 1150 W; the Intel part has no suggested PSU listed. The bus interface is PCIe 5.0 x16 for the AMD part and IGP for the Intel part. Display outputs are "No outputs" for the AMD part and "Portable Device Dependent" for the Intel part.

The release dates are 2023-12-05 for the AMD part and 2026-04-15 for the Intel part. Neither part has a launch MSRP listed. The AMD predecessor is FirePro Data Center, while the Intel predecessor is HD Graphics-M. Production status is null for the AMD part and Active for the Intel part.

Architecture Differences

The AMD Radeon Instinct MI300A uses CDNA 3.0 architecture, which is optimized for compute workloads. The Intel Arc Graphics 2 Xe Mobile uses Xe3-LPG architecture, which is designed for integrated graphics in mobile devices. The AMD part has a transistor density of 150.4M per mm², while the Intel part has no density figure listed.

The memory architecture is fundamentally different. The AMD part uses dedicated HBM3 memory with 192 GB capacity, 8192-bit bus width, and 10.3 TB/s bandwidth. The Intel part uses System Shared memory, meaning it has no dedicated VRAM. Its bandwidth is System Dependent, so the database records no fixed number.

The FP16 ratios reveal different compute strategies. The AMD part delivers 653.7 TFLOPS in FP16 at an 8:1 ratio, meaning it achieves this number by using eight times fewer operations than FP32. The Intel part delivers 2.560 TFLOPS at a 2:1 ratio, which is a more typical consumer ratio. The AMD part is clearly built for AI and HPC workloads that benefit from packed FP16 math.

The Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part has no API support listed, consistent with its role as a compute accelerator rather than a graphics renderer. The Intel part has display outputs, the AMD part has none. The Intel part uses an IGP bus interface, while the AMD part uses PCIe 5.0 x16.

The process node difference is notable: 5 nm for AMD at TSMC versus 3 nm for Intel at its own foundry. The AMD die is 1017 mm², which is a very large die. The Intel die size is unknown, but the part is an IGP, so it is likely integrated into a larger package. The transistor count for the AMD part is 153,000 million, while the Intel part has an unknown count.

The Verdict

The data separates these two parts cleanly. The AMD Radeon Instinct MI300A is a compute accelerator with 81.72 TFLOPS FP32, 192 GB of HBM3, and 10.3 TB/s bandwidth. The Intel Arc Graphics 2 Xe Mobile is an integrated GPU with 1.28 TFLOPS FP32, shared system memory, and a 25 W TDP. There is no overlap in their intended use cases.

The AMD part should be selected by anyone operating a data center or HPC environment where raw compute throughput and massive memory capacity are the primary requirements. Its 750 W TDP and OAM Module form factor are consistent with server installations that have dedicated power delivery and cooling. The lack of display outputs and graphics API support is irrelevant in such contexts. The 653.7 TFLOPS FP16 throughput indicates strong AI acceleration capability.

The Intel part should be selected for portable devices where power consumption and integration are the primary constraints. Its 25 W TDP, IGP form factor, and support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 make it suitable for graphics rendering on mobile platforms. The 2 ray tracing cores provide hardware ray tracing support, and the boost clock of 2500 MHz is higher than the AMD part. The production status of Active indicates it is currently available.

Neither part has benchmark scores in the database, so no measured performance comparison is possible. The specification data alone is sufficient to determine that the AMD part is a server accelerator and the Intel part is a mobile integrated GPU. Any workload that requires both parts would be unusual. The AMD part has no display outputs, so it cannot drive a monitor. The Intel part has a fraction of the compute throughput, so it cannot handle large-scale compute workloads. The choice is determined entirely by the target platform.
