AMD Instinct MI300 vs Intel Arc Graphics 2 Xe Mobile Comparison

The AMD Instinct MI300 and Intel Arc Graphics 2 Xe Mobile occupy opposite ends of the hardware spectrum. The MI300 is a server-oriented accelerator built for massive parallel computation, while the Arc Graphics 2 Xe Mobile is an integrated graphics solution for portable devices. The database contains no shared benchmark scores for these two products, so direct performance comparisons must be derived from their recorded specifications, architectural details, and the limited context of their respective categories.

Head-to-Head Benchmarks

The database lists no head-to-head benchmark results for these two devices. Neither product has recorded benchmark scores, average scores, or nearest rival data. This absence of direct measurement data means the comparison must rest entirely on the documented specifications. The MI300 delivers 47.87 TFLOPS of FP32 performance and 47.87 TFLOPS of FP16 performance with a 1:1 ratio. The Arc Graphics 2 Xe Mobile delivers 1,280.0 GFLOPS of FP32 performance, which converts to 1.28 TFLOPS, and 2.560 TFLOPS of FP16 performance with a 2:1 ratio. The MI300 therefore provides roughly 37 times the FP32 throughput and roughly 18.7 times the FP16 throughput of the Intel mobile part. These are not measured benchmark scores but calculated ratios from the recorded specification data.

The memory systems differ just as dramatically. The MI300 uses 128 GB of HBM3 memory on an 8192-bit bus, achieving 5.32 TB/s of bandwidth. The Arc Graphics 2 Xe Mobile uses system shared memory with a system dependent bandwidth figure. The MI300's dedicated memory bandwidth of 5.32 TB/s exceeds anything a shared system memory configuration can reasonably provide, though the exact comparison cannot be quantified because the database records the Intel part's bandwidth as "System Dependent."

The texture and pixel processing rates reveal the same gap. The MI300 has a texture rate of 1,496.0 GTexel/s, while the Intel part manages 40.00 GTexel/s, a 37.4 times difference. The MI300 has 0 ROPs and a pixel rate of 0 MPixel/s, because it is not designed for rasterized display output. The Intel part has 8 ROPs and a pixel rate of 20.00 GPixel/s. The MI300 has no display outputs, while the Intel part's display outputs are portable device dependent. These numbers show that the MI300 is optimized for compute workloads where pixel output is irrelevant, while the Intel part is built for rendering to a screen.

Clock behavior also separates the two. The MI300 has a base clock of 1000 MHz and a boost clock of 1700 MHz, with memory clocked at 1300 MHz or 5.2 Gbps effective. The Intel part has a base clock of 300 MHz and a boost clock of 2500 MHz. The Intel part relies on aggressive boosting to reach its performance envelope, while the MI300 runs at a comparatively modest boost clock but compensates with a massive chip and memory subsystem. The power envelope explains this: the MI300 has a TDP of 600 W, while the Intel part has a TDP of 25 W. The MI300 uses 2x 8-pin power connectors and suggests a 1000 W power supply. The Intel part uses no power connectors and has no suggested power supply, as it is an IGP.

The Verdict

The recorded data indicates that the AMD Instinct MI300 is overwhelmingly more powerful in raw compute throughput, memory capacity, memory bandwidth, and texture processing. The Intel Arc Graphics 2 Xe Mobile is overwhelmingly more efficient in power consumption, offers display output capability, supports a full API stack, and runs at a much higher boost clock. Neither product can substitute for the other. The MI300 has no display outputs, no DirectX support, no OpenGL support, and no Vulkan support; its APIs are recorded as N/A. The Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300 is a compute accelerator for data center workloads that do not require graphics output. The Intel part is an integrated GPU for laptops and portable devices that must render a user interface and run graphics applications.

The MI300's 153,000 million transistors on a 1017 mm² die at a 5 nm TSMC process gives a transistor density of 150.4M per mm². The Intel part's transistor count and die size are unknown, but it is built on a 3 nm Intel process. The MI300 uses the CDNA 3.0 architecture, while the Intel part uses Xe3-LPG. The MI300 has 14,080 shading units, 880 texture mapping units, and no ray tracing cores. The Intel part has 256 shading units, 16 texture mapping units, 8 ROPs, and 2 ray tracing cores. The MI300's FP16 performance is equal to its FP32 performance at a 1:1 ratio, while the Intel part's FP16 performance is double its FP32 performance at a 2:1 ratio. This suggests the Intel part is optimized for workloads that benefit from reduced precision, while the MI300 treats both precisions equally.

The production status also differs. The Intel part is recorded as Active, while the MI300's production status is not recorded. The MI300 was released on 2023-01-03, while the Intel part is scheduled for release on 2026-04-15. The MI300's predecessor is Radeon Instinct, and the Intel part's predecessor is HD Graphics-M. Neither product has a recorded successor. The MI300's dimensions are 267 mm in length and 111 mm in height, while the Intel part has no recorded dimensions because it is an IGP. The MI300 uses a PCIe 5.0 x16 bus interface, while the Intel part uses an IGP bus interface.

Architecture Differences

The MI300 is built on the CDNA 3.0 architecture, which is designed for compute acceleration. Its chip is called Aqua Vanjaram. The Intel part uses the Xe3-LPG architecture, which is designed for integrated graphics in mobile devices. Its chip is called Wildcat Lake. The MI300 belongs to the Instinct (MIx) generation, while the Intel part belongs to the Arc Graphics-M (Wildcat Lake) generation.

The manufacturing processes diverge. The MI300 uses a 5 nm process at TSMC. The Intel part uses a 3 nm process at Intel. The MI300's transistor count is 153,000 million, and its die size is 1017 mm². The Intel part's transistor count and die size are recorded as unknown. The MI300's transistor density is 150.4M per mm², while the Intel part has no recorded density. A 5 nm process with a 1017 mm² die indicates a very large, high-power chip. A 3 nm process with an IGP form factor indicates a small, low-power design integrated into a processor package.

The memory architectures are fundamentally different. The MI300 uses 128 GB of HBM3 with an 8192-bit bus and 5.32 TB/s bandwidth. The Intel part uses system shared memory with system dependent bandwidth. HBM3 is stacked memory placed close to the compute die, enabling enormous bandwidth. System shared memory uses the host system's main memory, which is slower and shared with the CPU. The MI300's memory clock is 1300 MHz or 5.2 Gbps effective, while the Intel part's memory clock is recorded as system shared.

The compute resources differ in scale and type. The MI300 has 14,080 shading units, 880 TMUs, and 0 ROPs. The Intel part has 256 shading units, 16 TMUs, 8 ROPs, and 2 ray tracing cores. The MI300 has no ray tracing cores, while the Intel part has 2. The MI300 has no recorded tensor cores, and the Intel part also has no recorded tensor cores. The MI300's pixel rate is 0 MPixel/s, while the Intel part's pixel rate is 20.00 GPixel/s. The MI300's texture rate is 1,496.0 GTexel/s, while the Intel part's texture rate is 40.00 GTexel/s.

The API support shows the intended use cases. The MI300 has no DirectX, OpenGL, or Vulkan support, all recorded as N/A. The Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means the MI300 cannot run graphics APIs and is not intended for rendering. The Intel part fully supports modern graphics APIs and can run games and graphics applications.

The power delivery systems are entirely different. The MI300 has a TDP of 600 W, uses 2x 8-pin power connectors, and suggests a 1000 W power supply. The Intel part has a TDP of 25 W, uses no power connectors, and has no suggested power supply. The MI300 is a discrete accelerator card with its own power delivery. The Intel part is an integrated GPU that draws power from the host processor's power delivery.
