Q: What API support does each GPU offer?

A: The AMD Radeon R5 M420 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The Intel Arc Pro B60 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it the more forward-looking option for modern workloads.

Architecture Differences

The architectural gap between these two GPUs is enormous, spanning nearly a decade of silicon evolution. The AMD Radeon R5 M420 is built on GCN 1.0 architecture, specifically the "Jet" chip, fabricated on a 28 nm TSMC process. It contains 690 million transistors on a 56 mm² die, yielding a transistor density of 12.3M per mm². This is an integrated graphics part (IGP) with a slot width designation of "IGP," meaning it was designed for portable devices rather than discrete expansion cards.

The Intel Arc Pro B60, in contrast, uses the Xe2-HPG architecture with the "BMG-G21" chip, built on a 5 nm TSMC process. It packs 19,600 million transistors onto a 272 mm² die, achieving a transistor density of 72.1M per mm². That density is roughly 5.9 times higher than the AMD part, reflecting the advanced process node and modern design philosophy. The Intel card is a dual-slot discrete GPU with dimensions of 167 mm in length, 69 mm in height, and 40 mm in width.

The shading engine counts tell a similar story. The AMD Radeon R5 M420 has 320 shading units, 20 texture mapping units, and 8 ROPs. The Intel Arc Pro B60 has 2,560 shading units, 160 TMUs, and 80 ROPs, each exactly eight times the AMD count. The Intel part also includes 20 ray tracing cores, a feature entirely absent from the AMD GPU, which has no RT cores listed.

Memory architecture differs fundamentally as well. The AMD card uses DDR3 at a 64-bit bus width, while the Intel card uses GDDR6 at a 192-bit bus width. The memory clock for the AMD part is 1000 MHz (2 Gbps effective), while the Intel part runs at 2375 MHz (19 Gbps effective). The bandwidth figures, 16.00 GB/s versus 456.0 GB/s, underscore the generational leap in memory technology.

The bus interface also differs: the AMD card uses PCIe 3.0 x8, while the Intel card uses PCIe 5.0 x8, providing substantially more bandwidth for data transfer between the GPU and the host system. Display outputs are "Portable Device Dependent" for the AMD card, whereas the Intel card offers 4x mini-DisplayPort 2.1 connectors.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs, so the comparison relies on the individual benchmark suites recorded for each card. The AMD Radeon R5 M420 has a single benchmark entry: Geekbench OpenCL with a score of 3956. The Intel Arc Pro B60 has eight benchmark entries covering various DirectX and compute workloads.

Looking at the Intel card's results, the PassMark G3D score of 14580 stands out as its strongest metric. The PassMark GPU Compute score of 7029 indicates solid compute performance. The DirectX scores show a pattern: DirectX 9 yields 179, DirectX 10 yields 61, DirectX 11 yields 122, and DirectX 12 yields 76. The PassMark G2D score is 763.

The average benchmark score for the AMD card is 3956, while the Intel card's average is 3182. However, these averages are not directly comparable because the benchmark suites differ entirely. The AMD card has only one OpenCL test, while the Intel card's average includes multiple PassMark tests that may weight differently.

The nearest rival data provides context. The AMD card's closest competitor, the NVIDIA GeForce 830M, scores 3957, a 0% delta. The NVIDIA Quadro K2000 scores 3964, a 0.2% delta in favor of the Quadro. The AMD Radeon HD 6850 X2 scores 3977, a 0.5% delta. These are all within a tight 0.5% band, suggesting the R5 M420 performs in a very narrow competitive range.

For the Intel Arc Pro B60, the nearest rival is the NVIDIA Quadro P1000 at 3163, a 0.6% delta in favor of Intel. The NVIDIA GeForce GT 640 scores 3210, a 0.9% delta against Intel. The NVIDIA GeForce 920M scores 3287, a 3.2% delta against Intel. Interestingly, the NVIDIA GeForce RTX 5080 SUPER scores 3075, a 3.5% delta in favor of Intel, placing the Arc Pro B60 slightly ahead of a much newer high-end card in this specific average.

The Verdict

The data paints an unambiguous picture for raw performance: the Intel Arc Pro B60 is in a completely different class. Its FP32 throughput of 12.29 TFLOPS versus 544.0 GFLOPS, its 456.0 GB/s bandwidth versus 16.00 GB/s, and its 2,560 shading units versus 320 all point to a GPU designed for professional workloads, not integrated portable graphics.

However, the percentile rankings complicate the narrative. The AMD Radeon R5 M420 ranks at the 23rd percentile, while the Intel Arc Pro B60 ranks at the 20th percentile. This counterintuitive result stems from the different benchmark suites recorded for each card. The AMD card's single Geekbench OpenCL score of 3956 places it in a tight cluster with rivals like the NVIDIA GeForce 830M (3957) and the NVIDIA Quadro K2000 (3964). The Intel card's average of 3182 is dragged down by low DirectX scores (61 for DX10, 76 for DX12, 122 for DX11) even though its PassMark G3D score of 14580 is massive.

The Intel card's nearest rival data shows it trading blows with much older hardware: the NVIDIA Quadro P1000 (3163) is 0.6% behind, the NVIDIA GeForce GT 640 (3210) is 0.9% ahead, and the NVIDIA GeForce 920M (3287) is 3.2% ahead. The presence of the NVIDIA GeForce RTX 5080 SUPER (3075) in the rival list, with Intel 3.5% ahead, suggests the average score may not fully capture the Arc Pro B60's capabilities in modern workloads.

For users seeking maximum compute and memory throughput, the Intel Arc Pro B60 is the obvious choice. For users constrained to integrated graphics in portable devices, the AMD Radeon R5 M420 represents the only option of the two, as it requires no expansion slot.

Where Each One Wins

The Intel Arc Pro B60 wins decisively in every performance category recorded in the database. Its FP32 compute of 12.29 TFLOPS dwarfs the AMD card's 544.0 GFLOPS, making it suitable for compute-heavy tasks like rendering, simulation, and machine learning inference. Its 24 GB of GDDR6 memory with 456.0 GB/s bandwidth allows it to handle large datasets and high-resolution textures that would be impossible on a 4 GB DDR3 buffer with 16.00 GB/s bandwidth.

The Intel card's ray tracing cores, 20 in total, give it capabilities that the AMD card simply lacks. Its DirectX 12 Ultimate support enables modern gaming and professional graphics features, while the AMD card's DirectX 12 (11_1) support is a legacy feature set. The Intel card's pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s are 28.2 and 22.6 times the AMD card's respective rates, making it far more capable at high resolutions and complex scene rendering.

The AMD Radeon R5 M420 wins in the narrow context of integrated graphics deployment. As an IGP with portable-device-dependent outputs, it requires no power connectors and has no TDP listed, making it suitable for thin-and-light laptops where space and cooling are constrained. Its 28 nm process and 690 million transistors consume far less power than the Intel card's 200 W TDP, though the database does not list a specific TDP for the AMD part.

In terms of benchmark distribution, the AMD card has a single score (3956) that clusters tightly with its nearest rivals, all within 0.5% of each other. This suggests consistent performance across similar hardware. The Intel card shows more variance across its eight benchmark scores, with the PassMark G3D score (14580) far exceeding the DirectX-specific scores, indicating strong overall graphics performance but weaker results in specific legacy API tests.

For users prioritizing compute density, the Intel Arc Pro B60's 72.1M transistors per mm² versus 12.3M for AMD reflects a modern design that extracts more performance from each square millimeter of silicon. For users prioritizing compatibility with older systems, the AMD card's PCIe 3.0 x8 interface is more broadly compatible than the Intel card's PCIe 5.0 x8, though both use x8 lanes. The Intel card's 4x mini-DisplayPort 2.1 outputs provide professional display connectivity, while the AMD card's outputs depend entirely on the host device.

The production status difference is stark: the AMD Radeon R5 M420 is end-of-life, while the Intel Arc Pro B60 is active. This means the Intel card is available for new deployments, while the AMD card exists only in existing systems or the secondhand market. The release dates, 2016 versus 2025, confirm that these products target entirely different eras and use cases.
