AMD Instinct MI300 vs Intel Arc Graphics 4 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results between the AMD Instinct MI300 and the Intel Arc Graphics 4 Xe Mobile. Both entries have an average benchmark score of 0 and no benchmark entries populate their respective fields. Consequently, no direct performance comparisons can be drawn from measured data. The percentileVsAllGpus field places both at the 50th percentile, though this value is not derived from any actual scored tests. What the data does provide is a clear specification-level contrast that allows for inference about relative capability. The AMD part delivers 47.87 TFLOPS of FP32 compute, while the Intel part delivers 2.355 TFLOPS. That represents a 20.3x difference in raw single-precision throughput. In FP16, the AMD part also outputs 47.87 TFLOPS on a 1:1 basis, whereas the Intel part reaches 4.710 TFLOPS via a 2:1 rate, a 10.2x gap. Texture rate shows a similar imbalance: 1,496.0 GTexel/s for the AMD accelerator versus 73.60 GTexel/s for the Intel integrated solution, a factor of roughly 20.3x. Pixel rate is more lopsided still, with the AMD part recording 0 MPixel/s because it has no ROPs, while the Intel part manages 36.80 GPixel/s. The absence of ROPs on the AMD part means it cannot rasterize in the conventional sense, which is a defining architectural difference rather than a benchmark loss.

Architecture Differences

The two processors occupy opposite ends of the GPU design spectrum. The AMD Instinct MI300 uses the CDNA 3.0 architecture, built on the Aqua Vanjaram chip, and is manufactured on a 5 nm process at TSMC. It integrates 153,000 million transistors on 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, built on the Panther Lake chip, and is manufactured on a 3 nm process at Intel. Its transistor count and die size are listed as unknown, and no density figure is recorded. The AMD part is a discrete accelerator with a PCIe 5.0 x16 bus interface and dual 8-pin power connectors, while the Intel part is an integrated graphics processor (IGP) with no power connectors and a system-dependent memory configuration.

Memory architecture differs fundamentally. The AMD Instinct MI300 has 128 GB of HBM3 memory on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The Intel Arc Graphics 4 Xe Mobile uses system-shared memory with a system-dependent bandwidth, meaning its performance scales with the host platform's memory subsystem rather than dedicated VRAM. Clock behavior also diverges. The AMD part runs at a 1000 MHz base clock and 1700 MHz boost, with memory clocked at 1300 MHz (5.2 Gbps effective). The Intel part has a 300 MHz base clock and a 2300 MHz boost, with no dedicated memory clock. Shading units number 14,080 on the AMD accelerator versus 512 on the Intel part. Texture mapping units total 880 versus 32. The AMD part has 0 ROPs, while the Intel part has 16. The Intel part includes 4 ray tracing cores; the AMD part lists no RT cores. The AMD part has no display outputs, while the Intel part has portable-device-dependent outputs. API support is also asymmetric: the AMD part lists N/A for DirectX, OpenGL, and Vulkan, whereas the Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Power consumption differs by an order of magnitude: the AMD part has a 600 W TDP and a suggested PSU of 1000 W, while the Intel part has a 25 W TDP.

Where Each One Wins

The AMD Instinct MI300 wins decisively in raw compute throughput. Its FP32 output of 47.87 TFLOPS is suited for dense matrix operations, large-scale scientific simulation, and high-bandwidth data movement. The 5.32 TB/s memory bandwidth and 128 GB capacity support workloads that exceed the memory ceiling of typical client GPUs. The 1:1 FP16 ratio means the part does not sacrifice half-precision throughput, which aligns with training and inference tasks that rely on reduced precision. The 1,496.0 GTexel/s texture rate indicates strong fill-rate capability for texture-heavy compute kernels, even though the part cannot output pixels due to the absence of ROPs. The PCIe 5.0 x16 interface provides a wide host link for data transfer.

The Intel Arc Graphics 4 Xe Mobile wins in integration, power efficiency, and graphics API coverage. Its 25 W TDP fits within mobile power envelopes, and its IGP form factor requires no discrete power connectors or additional slot space. The 36.80 GPixel/s pixel rate, while modest, is functional for display output and rasterization tasks. The 16 ROPs enable conventional rendering, and the 4 ray tracing cores add hardware-accelerated ray tracing support. DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support means the part can run modern graphics applications, including those with ray tracing and mesh shaders. The 2300 MHz boost clock is high for an integrated part, and the 2:1 FP16 ratio doubles throughput to 4.710 TFLOPS for workloads that can use it. System-shared memory removes the need for dedicated VRAM allocation, simplifying system design. The 3 nm process node suggests advanced manufacturing efficiency, though no density or transistor figures are available to quantify it.

The Verdict

The data supports a clear split. The AMD Instinct MI300 is a server-oriented accelerator for compute-heavy, non-rasterized workloads. Its 47.87 TFLOPS FP32, 47.87 TFLOPS FP16, 5.32 TB/s memory bandwidth, and 128 GB HBM3 capacity place it in a category for high-performance computing, AI training, and data-center inference. The absence of ROPs and display outputs means it is not intended for conventional graphics output. The 600 W TDP and 1000 W suggested PSU confirm a rack-mounted, power-rich environment. The Intel Arc Graphics 4 Xe Mobile is a client-oriented integrated GPU for mobile devices. Its 512 shading units, 16 ROPs, 4 ray tracing cores, and full DirectX 12 Ultimate support make it suitable for everyday graphics, light gaming, and portable device rendering. The 25 W TDP and IGP form factor fit into power-constrained laptops. The 2.355 TFLOPS FP32 is modest but adequate for integrated-class tasks. For a user selecting between these, the choice is dictated by workload class: data-center compute versus mobile graphics. The AMD part has no rasterization path, and the Intel part has no discrete memory or compute scale. Neither part competes in the other's domain.
