Intel Arc Pro B70 vs Intel Iris Xe Graphics 80EU Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results for the Intel Arc Pro B70 against the Intel Iris Xe Graphics 80EU Mobile. The database contains zero comparison scores for these two parts, and each holds a percentile ranking of 50 among all GPUs, with an average benchmark score of 0. This absence of measured results means any performance differentiation must be derived from the architectural specifications rather than direct test data.

The raw compute figures indicate a massive gap in theoretical throughput. The Arc Pro B70 delivers 22.94 TFLOPS of FP32 compute, which is more than 12 times the 1.856 TFLOPS produced by the Iris Xe Graphics 80EU Mobile. Pixel throughput tells a similar story: the Arc Pro B70 reaches 358.4 GPixel/s compared to 29.00 GPixel/s for the integrated part, a difference of roughly 12.4x. Texture rate stands at 716.8 GTexel/s versus 58.00 GTexel/s, again a 12.4x margin. These ratios are consistent across all three rate metrics, reflecting the proportional scaling of shading units, texture mapping units, and render output units.

The memory subsystem creates an even wider divide. The Arc Pro B70 uses 32 GB of GDDR6 on a 256-bit bus, yielding 608.0 GB/s of bandwidth. The Iris Xe Graphics 80EU Mobile relies on system shared memory, with bandwidth described only as "System Dependent" and no fixed capacity. For workloads that saturate memory bandwidth, the discrete card operates in a different performance class entirely.

Clock behavior also diverges sharply. The Arc Pro B70 runs at a 2280 MHz base clock and boosts to 2800 MHz. The Iris Xe part idles at 300 MHz base and reaches 1450 MHz boost. Even at their respective boost states, the Arc Pro B70 runs at nearly double the frequency of the integrated GPU.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The Arc Pro B70 uses the Xe2-HPG architecture, specifically the BMG-G31 chip, built on TSMC's 5 nm process. It belongs to the Battlemage (Pro Series) generation. The Iris Xe Graphics 80EU Mobile uses Generation 12.2, built on the Raptor Lake chip, manufactured on Intel's 10 nm process. It belongs to the HD Graphics-M (Raptor Lake) generation.

The die size difference is substantial: the Arc Pro B70 measures 368 mm², while the Iris Xe part has no listed die size, being an integrated component within a larger processor. Transistor counts are listed as unknown for both, so no direct comparison is possible.

Shader resources scale with the architecture. The Arc Pro B70 contains 4096 shading units, 256 texture mapping units, and 128 render output units. It also integrates 32 ray tracing cores, a feature the Iris Xe Graphics 80EU Mobile lacks entirely. The integrated part has 640 shading units, 40 TMUs, and 20 ROPs. Neither GPU lists tensor cores.

API support differs in the DirectX version. The Arc Pro B70 supports DirectX 12 Ultimate (12_2), while the Iris Xe part supports DirectX 12 (12_1). Both list OpenGL 4.6 and Vulkan 1.4 support. The Arc Pro B70 also features a PCIe 5.0 x16 bus interface, whereas the Iris Xe Graphics 80EU Mobile connects via a Ring Bus, reflecting its integrated nature.

Memory technology represents a fundamental architectural split. The Arc Pro B70 has dedicated GDDR6 memory with fixed capacity and bandwidth. The Iris Xe part uses system shared memory, where capacity, bus width, and bandwidth all depend on the host system's configuration.

Where Each One Wins

The Arc Pro B70 wins decisively in every measured compute category. Its 32 GB of dedicated GDDR6 memory with 608.0 GB/s bandwidth supports workloads that require large datasets resident on the GPU. The 32 ray tracing cores enable hardware-accelerated ray tracing, a capability absent from the Iris Xe part. The dual-slot design with a 230 W TDP and dedicated power connector indicates sustained performance capability rather than power-constrained operation. The PCIe 5.0 x16 interface provides high-bandwidth host communication, and the fixed display outputs (1x HDMI 2.1a, 3x DisplayPort 2.1) support multi-monitor professional setups.

The Iris Xe Graphics 80EU Mobile wins in integration efficiency. Its 15 W TDP requires no separate power delivery, no cooling solution beyond the laptop chassis, and no expansion slot. The system shared memory model means the GPU leverages whatever RAM the host provides, with no dedicated memory allocation required. The Ring Bus interface eliminates the need for a PCIe connection. Its 300 MHz base clock and 1450 MHz boost clock reflect a power-conscious design optimized for battery operation. The production status is listed as active, while the Arc Pro B70's production status is not listed. The Iris Xe part also has a successor (Arc Graphics-M), indicating an established product line.

The Verdict

The data supports a clear separation of use cases. The Intel Arc Pro B70 targets professional workloads that demand maximum compute throughput: 22.94 TFLOPS FP32, 358.4 GPixel/s pixel rate, 716.8 GTexel/s texture rate, and 32 GB of GDDR6 memory. Its 12.4x advantage in every rate metric over the Iris Xe Graphics 80EU Mobile places it in a different performance category entirely. The presence of 32 ray tracing cores, DirectX 12 Ultimate support, and PCIe 5.0 x16 connectivity further distinguishes it as a discrete solution for rendering, simulation, and content creation.

The Intel Iris Xe Graphics 80EU Mobile serves integrated, power-constrained environments. Its 15 W TDP, system shared memory, and portable device dependent display outputs align with thin-and-light laptops where battery life and thermal limits take precedence over raw performance. The 640 shading units and 1.856 TFLOPS provide basic graphics acceleration for everyday computing, but the architectural gap to the Arc Pro B70 is substantial: 6.4x fewer shading units, 6.4x fewer TMUs, 6.4x fewer ROPs, and a 1450 MHz boost clock that is less than one-third of the discrete card's boost clock.

The release dates reinforce this positioning. The Iris Xe Graphics 80EU Mobile launched on 2023-01-03 and remains in active production. The Arc Pro B70 arrives on 2026-03-25 with a launch MSRP of 949 USD. The professional pricing tier, combined with the pro-series branding and dual-slot form factor, indicates a workstation-oriented product. The Iris Xe part, with no launch MSRP recorded, ships as an integrated component within mobile processors.

The verdict from the recorded specifications is unambiguous: the Arc Pro B70 is a high-performance discrete GPU for professional workloads, while the Iris Xe Graphics 80EU Mobile is an entry-level integrated GPU for portable devices. No benchmark overlap exists in the database, but the 12.4x gap in pixel rate, texture rate, and FP32 throughput establishes a performance hierarchy that architectural differences only reinforce. Systems requiring ray tracing, high-bandwidth memory, or sustained compute should use the Arc Pro B70. Systems prioritizing power efficiency, integration, and portability should use the Iris Xe Graphics 80EU Mobile.
