AMD Radeon Instinct MI300 vs Intel Arc Graphics 1 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no direct benchmark scores for either the AMD Radeon Instinct MI300 or the Intel Arc Graphics 1 Xe Mobile. Both entries show an average benchmark score of zero, and the head-to-head benchmark array is empty. The percentile versus all GPUs for both parts sits at 50, indicating the database has no measured performance data to differentiate them. Consequently, there are no exact numbers to walk through for wins in either direction. The absence of measured results means any comparison must rely entirely on architectural and specification data, not on observed performance.

The MI300 is an accelerator-class part with 14,080 shading units, 880 texture mapping units, and no raster operation pipelines, which explains its listed pixel rate of 0 MPixel/s. Its texture rate reaches 1,496.0 GTexel/s, and its FP32 throughput is 47.87 TFLOPS. The Arc Graphics 1 Xe Mobile, by contrast, is an integrated GPU with 128 shading units, 8 texture mapping units, and 4 ROPs. Its pixel rate is 9.200 GPixel/s, its texture rate is 18.40 GTexel/s, and its FP32 throughput is 588.8 GFLOPS. The MI300 delivers roughly 81 times the FP32 compute of the mobile part, but that figure comes from the specification sheet, not from any recorded benchmark run.

The MI300 also lists FP16 performance of 383.0 TFLOPS at an 8:1 ratio, while the Arc part lists 1,177.6 GFLOPS at a 2:1 ratio. The memory systems are fundamentally different: the MI300 uses 128 GB of HBM3 across an 8192-bit bus, yielding 6.55 TB/s of bandwidth. The Arc part uses system shared memory with bandwidth listed as system dependent. No memory clock is specified for the Intel part, while the MI300 runs its memory at 1600 MHz with 6.4 Gbps effective. These are specification differences, not measurement outcomes.

Where Each One Wins

Without benchmark scores, the wins must be inferred from the hardware characteristics recorded in the database. The AMD Radeon Instinct MI300 wins decisively in raw compute throughput, memory capacity, and memory bandwidth. Its 128 GB of HBM3 memory and 6.55 TB/s bandwidth are designed for data-center workloads where large datasets reside on the accelerator. The 8192-bit bus width is unmatched by any integrated solution. The 5 nm process node from TSMC with 153,000 million transistors on a 1017 mm² die gives it a transistor density of 150.4M per mm², which supports its massive compute array.

The Intel Arc Graphics 1 Xe Mobile wins in power efficiency and integration. Its 25 W TDP is a fraction of the MI300's 600 W TDP, making it suitable for portable devices where power draw is constrained. The 3 nm process node from Intel's own foundry is a smaller node, though the transistor count and die size are listed as unknown. The Arc part includes 1 ray tracing core, which the MI300 does not list at all, giving Intel a feature advantage for real-time graphics workloads. The Arc part also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI300 lists no API support in the database, reflecting its compute-focused design rather than a graphics-oriented feature set.

The MI300 has no display outputs, making it ineligible for any rendering-to-screen workload. The Arc part's display outputs are listed as portable device dependent, meaning it can drive displays in laptop and mobile form factors. The MI300 uses 2x 8-pin power connectors and suggests a 1000 W power supply, while the Arc part uses no power connectors and is an integrated graphics processor. The MI300 is 267 mm long and 111 mm tall, requiring a full expansion slot, whereas the Arc part is an IGP with no physical dimensions listed.

The Verdict

From the recorded data, the AMD Radeon Instinct MI300 is for compute-heavy data-center deployments where FP32 and FP16 throughput, large memory pools, and extreme bandwidth are the primary requirements. Its 47.87 TFLOPS FP32 and 383.0 TFLOPS FP16 performance place it in a category that no integrated GPU can approach. The 128 GB memory capacity and 6.55 TB/s bandwidth allow it to hold and stream massive datasets without host memory involvement. The lack of display outputs and graphics API support confirms its role as an accelerator, not a rendering device.

The Intel Arc Graphics 1 Xe Mobile is for portable devices that need modest graphics capability within a 25 W envelope. Its 588.8 GFLOPS FP32 and 1,177.6 GFLOPS FP16 performance are sufficient for basic rendering and media tasks on a laptop. The inclusion of a ray tracing core and support for modern graphics APIs makes it a functional graphics solution, unlike the MI300. Its system shared memory model eliminates the need for dedicated VRAM, which is appropriate for integrated designs.

The production status for the MI300 is not listed, while the Arc part is marked as active. The MI300 released on 2023-01-03, and the Arc part is dated 2026-04-15, indicating a later introduction for Intel's mobile graphics. The database shows no predecessor or successor for either part. The MI300's predecessor is listed as FirePro Data Center, while the Arc part's predecessor is HD Graphics-M. The MI300 has no successor listed, and neither does the Arc part.
