Architecture Differences

The two GPUs come from different architectural lineages. The Arc Pro B60 Dual is built on Xe2-HPG, which is Intel's high-performance graphics architecture for discrete GPUs, specifically from the Battlemage Pro Series. This architecture is designed for workstation-class workloads, with dedicated ray tracing cores (20 of them) and support for DirectX 12 Ultimate. The chip is designated BMG-G21, fabricated on a 5 nm process at TSMC, with 19,600 million transistors on a 272 mm² die, yielding a transistor density of 72.1M per mm².

The Iris Xe Graphics 80EU Mobile is based on Generation 12.2 architecture, which is the integrated graphics solution within Raptor Lake mobile processors. It uses Intel's 10 nm process and does not have dedicated ray tracing cores. The chip is simply labeled Raptor Lake, with no separate transistor count or die size listed in the database. Its architecture is more modest, targeting power efficiency and basic graphical output rather than heavy compute.

The API support reflects this gap. The Arc Pro B60 Dual supports DirectX 12 Ultimate with feature level 12_2, which includes hardware ray tracing and mesh shaders. The Iris Xe 80EU supports DirectX 12 with feature level 12_1, which omits some of the more advanced rendering features. Both support OpenGL 4.6 and Vulkan 1.4, but the underlying hardware capabilities differ substantially.

The memory architecture also diverges completely. The Arc Pro B60 Dual has dedicated GDDR6 memory with a 192-bit bus, allowing high-bandwidth access to 24 GB of VRAM. The Iris Xe 80EU shares system memory, meaning its performance is highly dependent on the laptop's RAM configuration and speed. The database lists its memory type, bus width, and bandwidth as system shared or system dependent, indicating no dedicated video memory.

Specification Differences

The specification table shows clear divergence across every measurable field. The Arc Pro B60 Dual has a base clock of 2000 MHz and a boost clock of 2400 MHz, while the Iris Xe 80EU has a base clock of 300 MHz and a boost of 1450 MHz. The discrete card's memory runs at 2375 MHz with 19 Gbps effective speed, while the integrated GPU's memory clock is listed as system shared.

Compute resources differ by a factor of four in shading units: 2560 versus 640. Texture mapping units are 160 versus 40, and ROPs are 80 versus 20. The Arc Pro B60 Dual has 20 ray tracing cores, while the Iris Xe 80EU has none listed. Pixel rate is 192.0 GPixel/s versus 29.00 GPixel/s, and texture rate is 384.0 GTexel/s versus 58.00 GTexel/s.

Power consumption is dramatically different: 400 W TDP for the discrete card versus 15 W for the integrated solution. The Arc Pro B60 Dual requires a dual-slot cooler, a 1x 16-pin power connector, and an 800 W suggested PSU. The Iris Xe 80EU is an IGP with no power connector or PSU recommendation. The bus interface is PCIe 5.0 x8 for the Arc Pro card, while the Iris Xe uses a Ring Bus.

Physical dimensions are only listed for the Arc Pro B60 Dual: 300 mm length, 110 mm height, and 40 mm width. The integrated GPU has no dimensions as it is embedded on the processor package. The Arc Pro card provides 4x mini-DisplayPort 2.1 outputs, while the Iris Xe's outputs depend on the portable device implementation.

Release dates differ as well: the Arc Pro B60 Dual was released on September 4, 2025, while the Iris Xe 80EU came out on January 3, 2023. The Iris Xe has a listed successor, Arc Graphics-M, while the Arc Pro B60 has no successor recorded. The Arc Pro B60 Dual has a launch MSRP of 1,199 USD; the Iris Xe has no launch MSRP listed.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for these two GPUs, and neither has recorded benchmark scores. Both are listed with an average benchmark score of 0 and a percentile rank of 50 against all GPUs. With no measured performance data available, the comparison must rely on the theoretical specifications.

The FP32 compute figures provide the clearest comparison. The Arc Pro B60 Dual delivers 12.29 TFLOPS, which is 6.6 times the 1.856 TFLOPS of the Iris Xe 80EU. This ratio holds for FP16 as well: 24.58 TFLOPS versus 3.712 TFLOPS, both at a 2:1 ratio relative to their FP32 numbers.

Memory bandwidth shows an even larger gap. The Arc Pro B60 Dual has 456.0 GB/s of dedicated bandwidth, while the Iris Xe 80EU's bandwidth is system dependent, meaning it cannot be stated as a fixed number. The 24 GB of VRAM versus system shared memory also indicates the discrete card can handle much larger datasets without spilling to system RAM.

Pixel throughput favors the Arc Pro card by a factor of about 6.6: 192.0 GPixel/s versus 29.00 GPixel/s. Texture throughput shows a similar ratio: 384.0 GTexel/s versus 58.00 GTexel/s. These ratios align with the shading unit counts, confirming consistent scaling across the two designs.

Clock speeds tell a mixed story. The Arc Pro B60 Dual has a much higher base clock (2000 MHz vs 300 MHz) and a higher boost clock (2400 MHz vs 1450 MHz). However, the Iris Xe 80EU's boost clock of 1450 MHz is notable given its 15 W power envelope, showing Intel's efficiency focus for integrated graphics.

Where Each One Wins

The Arc Pro B60 Dual wins in every absolute performance category recorded. Its 12.29 TFLOPS FP32 compute, 24 GB GDDR6 memory, 456.0 GB/s bandwidth, and 20 ray tracing cores make it suitable for professional 3D rendering, video editing, and compute workloads. The DirectX 12 Ultimate support enables hardware ray tracing and advanced rendering features, which the Iris Xe 80EU cannot provide with its DirectX 12 (12_1) support and no RT cores.

The Iris Xe 80EU wins in power efficiency and integration. Its 15 W TDP is 26 times lower than the Arc Pro B60 Dual's 400 W TDP. This makes it suitable for thin-and-light laptops where battery life and thermal management are critical. As an IGP, it requires no additional space, power connector, or PSU recommendation, making it a zero-footprint solution for everyday computing, video playback, and light productivity.

The Arc Pro B60 Dual requires a dual-slot cooler, a 1x 16-pin power connector, an 800 W PSU, and measures 300 mm in length. This confines it to desktop workstations with adequate chassis space and power delivery. The Iris Xe 80EU has no such requirements, functioning entirely within the host laptop's existing power and thermal budget.

For display connectivity, the Arc Pro B60 Dual offers 4x mini-DisplayPort 2.1 outputs, supporting multi-monitor professional setups. The Iris Xe 80EU's outputs are portable device dependent, meaning the laptop manufacturer decides what ports are available. This gives the discrete card a clear advantage for multi-display workstation configurations.

The Iris Xe 80EU has a successor listed as Arc Graphics-M, indicating Intel's roadmap for integrated graphics evolution. The Arc Pro B60 Dual has no successor recorded, suggesting it is a current-generation product without a known replacement. Both are marked as active in production status.
