AMD Radeon PRO W7400 vs Intel Arc B580 Comparison

Head-to-Head Benchmarks

The recorded data does not include direct head-to-head benchmark scores between the AMD Radeon PRO W7400 and the Intel Arc B580. The AMD Radeon PRO W7400 entry carries no benchmark scores, an average benchmark score of zero, and no nearest rivals. The Intel Arc B580, by contrast, has an extensive benchmark record across multiple suites.

For the Intel Arc B580, the database shows its strongest result in Geekbench Vulkan with a score of 109672, followed by Geekbench OpenCL at 92821. In Passmark testing, the Arc B580 scores 15748 in G3D, 7729 in GPU Compute, 709 in G2D, 183 in DirectX 9, 128 in DirectX 11, 76 in DirectX 10, and 76 in DirectX 12. Its 3DMark Steel Nomad DX12 score is 3068.

The Arc B580's average benchmark score of 23021 places it at the 68th percentile among all GPUs in the database. Its nearest rivals, based on average scores, include the AMD Radeon RX 580 2048SP with an average score of 23061, a negligible 0.2 percent gap. The NVIDIA GeForce RTX 3080 sits at 23172, which is 0.7 percent above the Arc B580. The NVIDIA GeForce RTX 2080 trails by 0.6 percent with a score of 22895, and the NVIDIA P106-100 leads by 1 percent at 23249.

Since the AMD Radeon PRO W7400 has no recorded benchmarks, no comparative percentage deltas can be calculated. The database indicates zero wins for either card in head-to-head testing. The absence of scores for the W7400 means the measured data cannot substantiate any performance advantage for the AMD card in any specific workload category. The data confirms the Intel card's measured standing relative to four established GPUs, while the AMD card's relative position remains undefined.

Architecture Differences

The two GPUs represent distinct architectural generations from their respective manufacturers. The AMD Radeon PRO W7400 is built on the RDNA 3.0 architecture with the codename Hotpink Bonefish, belonging to the Radeon Pro Navi (Navi III Series) generation. The Intel Arc B580 uses the Xe2-HPG architecture and belongs to the Battlemage (Arc 5) generation.

Manufacturing processes differ: AMD employs a 6 nm process from TSMC, while Intel uses a 5 nm process, also from TSMC. The Intel chip integrates more transistors, 19,600 million against AMD's 13,300 million, and occupies a larger die at 272 mm² versus 204 mm². Transistor density favors Intel at 72.1M per mm² compared to AMD's 65.2M per mm².

Ray tracing hardware differs in count. The AMD card includes 28 ray tracing cores, while the Intel card has 20. Neither card lists tensor cores in the database. Pixel and texture processing rates diverge sharply: Intel delivers 213.6 GPixel/s and 427.2 GTexel/s, while AMD delivers 70.40 GPixel/s and 123.2 GTexel/s.

Compute throughput also diverges. The Intel Arc B580 reaches 13.67 TFLOPS for FP32 and 27.34 TFLOPS for FP16 at a 2:1 ratio. The AMD Radeon PRO W7400 achieves 7.885 TFLOPS for both FP32 and FP16, indicating a 1:1 ratio. The Intel card's FP16 capability is effectively double its FP32 rate, whereas the AMD card treats both with equal throughput.

Memory architecture reflects the same generational split. The Intel card uses a 192-bit bus with 12 GB capacity and 456.0 GB/s bandwidth. The AMD card uses a 128-bit bus with 8 GB capacity and 172.8 GB/s bandwidth. Memory clock rates also differ, with Intel at 2375 MHz (19 Gbps effective) and AMD at 1350 MHz (10.8 Gbps effective).

The Intel card's predecessor is Alchemist, while the AMD card's predecessor is Radeon Pro Vega. Both cards support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use a PCIe 4.0 x8 bus interface.

Specification Differences

The Intel Arc B580 and AMD Radeon PRO W7400 differ across nearly every recorded specification field. Clock speeds show the largest relative gap. The Intel card has a base and boost clock of 2670 MHz, while the AMD card has a base clock of 330 MHz and a boost of 1100 MHz.

Power requirements diverge substantially. The Intel card has a TDP of 190 W, requires a single 8-pin power connector, and suggests a 450 W power supply. The AMD card has a TDP of 55 W, requires no power connectors, and suggests a 250 W power supply.

Physical dimensions differ accordingly. The Intel card measures 272 mm in length, 115 mm in height, and 45 mm in width, occupying a dual-slot profile. The AMD card measures 168 mm in length, 69 mm in height, and 20 mm in width, fitting a single-slot profile.

Memory specifications: 12 GB versus 8 GB, 192-bit versus 128-bit bus width, 456.0 GB/s versus 172.8 GB/s bandwidth. The Intel card uses a 2:1 FP16 ratio; the AMD card uses 1:1.

Shading units, texture mapping units, and render output units all favor Intel: 2560 versus 1792 shading units, 160 versus 112 TMUs, and 80 versus 64 ROPs. Ray tracing cores favor AMD at 28 versus 20.

Display outputs differ. The AMD card provides 4x DisplayPort 2.1. The Intel card provides 1x HDMI 2.1a and 3x DisplayPort 2.1.

Release dates: the Intel Arc B580 was released on 2024-12-12, while the AMD Radeon PRO W7400 was released on 2025-08-02. The Intel card has a launch MSRP of 249 USD; the AMD card has no recorded launch MSRP.

The Intel card's average benchmark score is 23021 with a 68th percentile ranking. The AMD card's average benchmark score is 0 with a 50th percentile ranking. The database lists nearest rivals only for the Intel card.

The Verdict

The database presents a one-sided comparison. The Intel Arc B580 has a complete benchmark record, a 68th percentile ranking, and an average score of 23021. The AMD Radeon PRO W7400 has no recorded benchmarks, an average score of 0, and a 50th percentile ranking. Measured performance data exists only for the Intel card.

For users selecting based on recorded compute results, the Intel Arc B580 is the only card with substantiated scores. Its nearest rival comparisons show it within 1 percent of the AMD Radeon RX 580 2048SP, NVIDIA GeForce RTX 2080, NVIDIA GeForce RTX 3080, and NVIDIA P106-100. The 0.6 percent advantage over the RTX 2080 and the 0.7 percent deficit to the RTX 3080 indicate the Arc B580 sits in a tight competitive band among those GPUs.

The AMD Radeon PRO W7400 offers a different physical profile. Its 55 W TDP, single-slot design, and absence of power connectors contrast sharply with the Intel card's 190 W TDP, dual-slot design, and 8-pin connector. The AMD card is shorter, narrower, and thinner. The Intel card has more memory, higher bandwidth, more shading units, more TMUs, more ROPs, higher clocks, and higher pixel, texture, and compute rates.

The AMD card does lead in ray tracing core count with 28 against Intel's 20. It also released later, in August 2025 versus December 2024. The Intel card remains the only one with a launch MSRP, listed at 249 USD.

Given the data, the Intel Arc B580 is the better-documented performer. Its benchmark scores, percentile rank, and nearest rival comparisons provide a concrete basis for evaluation. The AMD Radeon PRO W7400 cannot be assessed on measured performance because the database contains none. Its advantages are limited to physical size, power draw, and ray tracing core count. For any workload requiring verified rendering or compute output, the recorded data points exclusively to the Intel Arc B580.
