AMD Radeon PRO W7400 vs Intel Arc Graphics 128EU Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no head-to-head benchmark entries for the AMD Radeon PRO W7400 versus the Intel Arc Graphics 128EU Mobile. Both products have an average benchmark score of zero in the database, and neither has a wins tally in direct comparison. This means the database currently lacks measured performance results for these two GPUs against each other or against other hardware. The percentile ranking for both is identical at 50, placing them exactly at the midpoint of all tracked GPUs. Without benchmark scores, any performance advantage must be inferred from the architectural and specification data rather than from direct measurements. The lack of recorded results does not indicate parity; it simply reflects an absence of submitted test data for this pairing.

Architecture Differences

The AMD Radeon PRO W7400 uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Radeon Pro Navi (Navi III Series) generation. It is manufactured on a 6 nm process at TSMC, with 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter. The Intel Arc Graphics 128EU Mobile uses the Meteor Lake chip with Xe-LPG architecture, part of the Arc Graphics-M (Meteor Lake) generation. Intel builds this on a 10 nm process at Intel foundry, but the database records no transistor count, die size, or density for this part. The process node difference is substantial: 6 nm versus 10 nm, which typically indicates the AMD chip uses a more advanced fabrication technology. However, the Intel part is an integrated graphics processor (IGP) with a slot width of IGP, while the AMD card is a discrete single-slot solution. The AMD GPU packs 1792 shading units, 112 texture mapping units, and 64 ROPs, plus 28 ray tracing cores. The Intel GPU has 1024 shading units, 64 TMUs, and 32 ROPs, with no dedicated ray tracing cores listed. The AMD card carries dedicated GDDR6 memory with a 128-bit bus and 172.8 GB/s bandwidth, while the Intel part uses system shared memory with system-dependent bandwidth. The AMD card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Intel GPU supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, meaning the AMD card has a higher DirectX feature level. The AMD card uses a PCIe 4.0 x8 interface, while the Intel IGP connects via a ring bus. The AMD card draws a maximum of 55 W and requires a 250 W suggested power supply, with no power connectors needed. The Intel part has a 28 W TDP.

The Verdict

The database shows two fundamentally different products. The AMD Radeon PRO W7400 is a discrete, single-slot graphics card with dedicated GDDR6 memory, a higher shading unit count, and ray tracing hardware. The Intel Arc Graphics 128EU Mobile is an integrated GPU sharing system memory, with fewer shading units and no dedicated ray tracing cores. The AMD card has a higher FP32 throughput at 7.885 TFLOPS versus 4.608 TFLOPS, giving it a 71% advantage in single-precision compute. The Intel part has a higher FP16 throughput at 9.216 TFLOPS versus 7.885 TFLOPS, but this comes from a 2:1 FP16 ratio, meaning the FP32 rate is halved. The Intel part also has a higher boost clock at 2250 MHz and higher pixel and texture rates at 72.00 GPixel/s and 144.0 GTexel/s, respectively. However, the AMD card has 75% more shading units, 75% more TMUs, 100% more ROPs, and dedicated memory bandwidth of 172.8 GB/s, which removes system memory contention. The AMD card's 55 W TDP is nearly double the Intel part's 28 W, but the AMD card is a discrete solution with its own cooling and power delivery. The Intel part is an IGP, meaning it relies on the host system's memory and cooling. For workloads that depend on raw FP32 compute, the AMD card is clearly ahead. For tasks that favor FP16 throughput or rely on higher clock speeds, the Intel part shows advantages. The AMD card also supports DirectX 12 Ultimate, which includes features like ray tracing and mesh shaders, while the Intel part only reaches DirectX 12_1. The release dates differ by over a year, with the Intel part launching in December 2023 and the AMD card in August 2025.

Where Each One Wins

The AMD Radeon PRO W7400 wins in scenarios that demand dedicated memory bandwidth, high FP32 compute, and hardware ray tracing. Its 172.8 GB/s bandwidth and 8 GB of GDDR6 memory make it suited for workloads that need stable, isolated memory access without competing with the CPU. Its 7.885 TFLOPS FP32 rate is 71% higher than the Intel part, which directly benefits compute-heavy tasks like rendering, simulation, or professional visualization. The 28 ray tracing cores give it a hardware advantage for ray-traced effects, while the DirectX 12 Ultimate support enables modern graphics features. The card's 55 W TDP and single-slot design make it a compact discrete solution, and its four DisplayPort 2.1 outputs support multi-display professional setups.

The Intel Arc Graphics 128EU Mobile wins in scenarios that favor high clock speeds, FP16 throughput, and low power consumption. Its 2250 MHz boost clock is more than double the AMD card's 1100 MHz, which helps in latency-sensitive tasks that respond to clock frequency. Its 9.216 TFLOPS FP16 rate exceeds the AMD card's 7.885 TFLOPS, giving it an edge for workloads that use half-precision arithmetic. The 28 W TDP is roughly half the AMD card's power draw, making it suitable for power-constrained mobile systems. Its 72.00 GPixel/s pixel rate and 144.0 GTexel/s texture rate are higher than the AMD card's 70.40 GPixel/s and 123.2 GTexel/s, indicating stronger fill-rate performance in certain rasterization tasks. As an IGP, it requires no separate card slot or power connectors, simplifying integration into compact devices. The ring bus interface ties it directly to the host processor, which can reduce latency for shared-memory operations. The 2023 release date also means it has been available longer in the market. For users prioritizing low power, high clock speed, or FP16 compute, the Intel part delivers those strengths. For users needing discrete memory, higher FP32 throughput, or ray tracing, the AMD card is the clear choice based on the recorded specifications.
