AMD Radeon Instinct MI300X vs Intel Arc Graphics 4 Xe Mobile Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Radeon Instinct MI300X or the Intel Arc Graphics 4 Xe Mobile. Both entries show an average benchmark score of 0, and the head-to-head benchmark list is empty. This absence of measured performance data means the comparison must rely entirely on the architectural and specification differences recorded in the database.

The MI300X posts a theoretical FP32 throughput of 81.72 TFLOPS, while the Intel part delivers 2.355 TFLOPS. The ratio is approximately 34.7:1 in favor of AMD. For FP16, the MI300X reaches 653.7 TFLOPS using an 8:1 ratio, whereas the Intel GPU produces 4.710 TFLOPS with a 2:1 ratio. The raw compute gap is substantial, but the two products serve entirely different market segments, so direct performance equivalence was never a design goal.

Texture fill rates tell a similar story. The MI300X achieves 2,553.6 GTexel/s, compared to 73.60 GTexel/s for the Intel chip. That is a 34.7x difference, mirroring the FP32 gap. Pixel rates, however, show a surprising inversion: the Intel part posts 36.80 GPixel/s, while the MI300X records 0 MPixel/s. The AMD accelerator has no raster output units (ROPs listed as 0), meaning it cannot perform traditional pixel rendering. The Intel GPU has 16 ROPs and is designed for display output, while the MI300X is a compute-focused accelerator with no display outputs at all.

Where Each One Wins

The MI300X wins decisively in compute throughput, memory capacity, and memory bandwidth. It offers 192 GB of HBM3 memory across an 8192-bit bus, delivering 10.3 TB/s of bandwidth. The Intel Arc Graphics 4 Xe Mobile uses system shared memory, with bandwidth described as "System Dependent." The AMD part has 19,456 shading units and 1,216 texture mapping units. The Intel GPU has 512 shading units and 32 TMUs. For any workload that scales with raw shader count, texture filtering, or memory bandwidth, the MI300X is the clear winner.

The Intel Arc Graphics 4 Xe Mobile wins in areas where the MI300X cannot compete. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300X lists null values for all three API categories, confirming it is not intended for graphics rendering. The Intel part also has 4 ray tracing cores, while the MI300X lists none. The Intel GPU has a production status of "Active," while the AMD part has no recorded production status. For mobile or embedded systems requiring graphics output, the Intel solution is the only viable option between the two.

The power envelope is another clear differentiator. The MI300X has a TDP of 750 W and requires a suggested PSU of 1150 W. The Intel part runs at 25 W TDP and is an IGP (integrated graphics processor) with no external power connectors needed. The MI300X uses an OAM Module slot width and has no power connectors listed, as it is designed for server racks with dedicated power delivery. The Intel chip is a mobile integrated solution.

Architecture Differences

The MI300X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, manufactured on a 5 nm process at TSMC. The Intel Arc Graphics 4 Xe Mobile uses the Panther Lake chip with Xe3-LPG architecture, built on a 3 nm process at Intel. The transistor counts differ enormously: the MI300X packs 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million per mm². The Intel chip has an unknown transistor count and die size.

The MI300X has a base clock of 1000 MHz and a boost clock of 2100 MHz. The Intel part runs at 300 MHz base and 2300 MHz boost. Despite the much lower base clock, the Intel chip's boost clock is higher, reflecting the mobile power budget and the different architecture goals. The MI300X's memory clock is 2525 MHz (10.1 Gbps effective), while the Intel part uses system shared memory with no dedicated clock.

The MI300X features 19,456 shading units, 1,216 TMUs, and 0 ROPs. The Intel GPU has 512 shading units, 32 TMUs, and 16 ROPs. The AMD accelerator lists no ray tracing cores, while the Intel chip includes 4. Neither product lists tensor cores in the database. The MI300X has a pixel rate of 0 MPixel/s, confirming the absence of rasterization hardware. The Intel part delivers 36.80 GPixel/s.

The bus interfaces are fundamentally different: the MI300X uses PCIe 5.0 x16, while the Intel part uses an IGP bus interface. Display outputs on the MI300X are "No outputs," whereas the Intel GPU lists "Portable Device Dependent" outputs. The MI300X has no recorded API support, while the Intel GPU supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

FAQ

Q: Which GPU has higher raw compute performance?

A: The AMD Radeon Instinct MI300X delivers 81.72 TFLOPS FP32 and 653.7 TFLOPS FP16 (8:1), compared to the Intel Arc Graphics 4 Xe Mobile's 2.355 TFLOPS FP32 and 4.710 TFLOPS FP16 (2:1).

Q: Can the MI300X render graphics for display output?

A: No. The MI300X has 0 ROPs, a pixel rate of 0 MPixel/s, no display outputs, and null API support. It is a compute accelerator, not a graphics card.

Q: What is the memory configuration difference?

A: The MI300X has 192 GB of HBM3 memory on an 8192-bit bus with 10.3 TB/s bandwidth. The Intel Arc Graphics 4 Xe Mobile uses system shared memory with system-dependent bandwidth.

Q: Which GPU supports ray tracing?

A: The Intel Arc Graphics 4 Xe Mobile has 4 ray tracing cores. The MI300X lists no ray tracing cores.

Q: What are the power requirements for each?

A: The MI300X has a 750 W TDP and a suggested PSU of 1150 W. The Intel Arc Graphics 4 Xe Mobile has a 25 W TDP and no suggested PSU listed.

Q: Which GPU is smaller in physical footprint?

A: The MI300X uses an OAM Module slot width and has a die size of 1017 mm². The Intel part is an IGP with unknown die size, designed for integration into mobile processors.

The Verdict

The data shows two products with almost no overlap in purpose. The AMD Radeon Instinct MI300X is a data center accelerator with massive compute throughput, 192 GB of HBM3 memory, and 10.3 TB/s bandwidth. It has no display outputs, no rasterization hardware, and no graphics API support. The Intel Arc Graphics 4 Xe Mobile is a mobile integrated GPU with 512 shading units, 4 ray tracing cores, and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support.

For compute workloads such as large-scale matrix operations, the MI300X's 81.72 TFLOPS FP32 and 653.7 TFLOPS FP16 performance, combined with the enormous memory bandwidth, makes it the only choice between these two. The Intel part's 2.355 TFLOPS FP32 is a fraction of the AMD accelerator's output.

For any graphics rendering, display output, or ray tracing task, the Intel Arc Graphics 4 Xe Mobile is the only functional option. The MI300X cannot output pixels at all. The Intel GPU's 36.80 GPixel/s pixel rate and 4 RT cores provide actual graphics capability, while the MI300X records zero pixel throughput.

The production status also differs: Intel lists the Arc Graphics 4 Xe Mobile as "Active," while the MI300X has no recorded production status. The release dates are 2023-12-05 for the AMD part and 2026-01-26 for the Intel part. The MI300X's predecessor is listed as FirePro Data Center, while the Intel part has no predecessor.

The choice depends entirely on the workload. Data center compute with no graphics needs points to the MI300X. Mobile graphics with ray tracing and API support points to the Intel part. Neither product competes in the other's segment.
