AMD Radeon 860M vs Intel Arc Pro B70 Comparison

Where Each One Wins

The AMD Radeon 860M and Intel Arc Pro B70 occupy entirely different segments of the graphics market, and the data reflects this split clearly. The Radeon 860M is an integrated graphics processor built for mobile devices, while the Arc Pro B70 is a discrete workstation card with a dual-slot cooler and a dedicated 8-pin power connector. Their benchmark profiles could not be more different.

The Radeon 860M has recorded benchmark results in the database. Its Geekbench OpenCL score of 22759 and Vulkan score of 30043 produce an average benchmark score of 26401. That average places it at the 72nd percentile among all GPUs in the database. The Intel Arc Pro B70, by contrast, has no recorded benchmark scores at all. Its average benchmark score sits at 0, and its percentile ranking is 50th, which reflects its unmeasured status rather than any actual performance deficit.

This means the Radeon 860M currently owns every measurable win in the database, but only because the Arc Pro B70 has not been tested yet. The Radeon's nearest rivals provide context for its position. It sits within 0.1% of the NVIDIA GeForce MX550, within 0.3% of the NVIDIA GeForce RTX 5060, within 0.6% of the AMD Radeon RX 5700 XT 50th Anniversary, and within 1.1% of the NVIDIA RTX A4000. These are tight margins, indicating the 860M performs in a well-established mid-range band despite being an integrated solution.

The Arc Pro B70's hardware specifications suggest it would dominate in raw throughput, but without benchmark data, the database cannot confirm this. Its FP32 compute of 22.94 TFLOPS versus the Radeon's 3.072 TFLOPS indicates a theoretical sevenfold advantage, and its 608.0 GB/s memory bandwidth versus the Radeon's system-dependent shared memory points to a massive gap in memory-bound workloads. The wins, therefore, are split between measured reality and theoretical capability.

Architecture Differences

The two GPUs come from different architectural lineages. The AMD Radeon 860M uses RDNA 3.5, built on a 4 nm TSMC process, and belongs to the Navi III IGP generation for Strix Point Mobile. The chip is called Krackan Point. The Intel Arc Pro B70 uses Xe2-HPG, built on a 5 nm TSMC process, and belongs to the Battlemage Pro Series with the BMG-G31 chip. The process node difference is small but real: 4 nm versus 5 nm.

The shader configurations diverge sharply. The Radeon 860M has 512 shading units, 32 texture mapping units, 16 render output units, and 8 ray tracing cores. The Arc Pro B70 has 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. That is an 8x difference in shading units, an 8x difference in TMUs, and an 8x difference in ROPs. The ray tracing core count is 4x higher on the Intel part.

Clock behavior also differs. The Radeon 860M runs a base clock of 600 MHz and boosts to 3000 MHz, a 5x boost range that reflects its power-constrained integrated design. The Arc Pro B70 runs a base clock of 2280 MHz and boosts to 2800 MHz, a much tighter range typical of a high-power discrete card. The Intel card's memory clock is listed at 2375 MHz with 19 Gbps effective data rate, while the AMD card uses system shared memory with no dedicated clock.

Memory architecture is a fundamental split. The Radeon 860M has system shared memory with system-dependent bandwidth, which means its performance scales with the host laptop's RAM configuration. The Arc Pro B70 has 32 GB of dedicated GDDR6 memory on a 256-bit bus, delivering 608.0 GB/s of bandwidth. The die size also differs: the Arc Pro B70 measures 368 mm², while the Radeon 860M's die size is listed as unknown in the database.

Power and physical design separate them further. The Radeon 860M is an IGP with a 15 W TDP, no power connectors, and a PCIe 4.0 x8 interface. The Arc Pro B70 is a dual-slot card with a 230 W TDP, one 8-pin power connector, a suggested 550 W power supply, and a PCIe 5.0 x16 interface. The Intel card measures 267 mm in length, 110 mm in height, and 39 mm in width. The Radeon has no dimensions because it is soldered onto a motherboard.

The API support is identical. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The display outputs differ: the Radeon's outputs are portable device dependent, while the Arc Pro B70 offers 1x HDMI 2.1a and 3x DisplayPort 2.1.

The Radeon 860M has a production status of Active. The Arc Pro B70 has no production status listed. The release dates are February 28, 2025 and March 25, 2026. The launch MSRP for the Arc Pro B70 is 949 USD, stated once here as recorded. The Radeon 860M has no launch MSRP in the database. The Radeon's predecessor is listed as Navi II IGP, while the Arc Pro B70 has no predecessor recorded.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Radeon 860M and the Arc Pro B70. The head-to-head benchmark array is empty, and the wins counter shows zero for both products. This is the central fact of their comparison: one product has measurements, the other does not.

The Radeon 860M's recorded scores stand alone. Its Geekbench OpenCL score of 22759 and Geekbench Vulkan score of 30043 combine to an average of 26401. That average places it in the 72nd percentile of all GPUs. The nearest rival data shows how competitive this integrated part is. The NVIDIA GeForce MX550 scores 26421, a delta of -0.1% from the Radeon. The NVIDIA GeForce RTX 5060 scores 26331, a delta of +0.3%. The AMD Radeon RX 5700 XT 50th Anniversary scores 26553, a delta of -0.6%. The NVIDIA RTX A4000 scores 26683, a delta of -1.1%.

These deltas tell a clear story. The Radeon 860M is statistically tied with all four rivals. The largest gap is 1.1%, which is within run-to-run variance for most benchmark suites. This means the integrated Radeon 860M delivers performance equivalent to a discrete mobile GPU like the MX550 and even matches desktop-class cards like the RX 5700 XT 50th Anniversary within a single percentage point.

The Arc Pro B70 offers no comparable data. Its average benchmark score is 0, its percentile is 50th, and its nearest rivals list is empty. The database cannot rank it against anything. What the specifications suggest, however, is a different class of hardware. The FP32 throughput of 22.94 TFLOPS is roughly 7.5 times the Radeon's 3.072 TFLOPS. The texture rate of 716.8 GTexel/s is roughly 7.5 times the Radeon's 96.00 GTexel/s. The pixel rate of 358.4 GPixel/s is roughly 7.5 times the Radeon's 48.00 GPixel/s. The memory bandwidth of 608.0 GB/s is a fixed number against the Radeon's system-dependent shared memory, which in typical laptop configurations would be a fraction of that figure.

The ray tracing comparison favors the Intel card as well. The Arc Pro B70 has 32 ray tracing cores versus the Radeon's 8, and the Xe2-HPG architecture is designed for workstation workloads. The Radeon's ray tracing capability in a 15 W integrated package is necessarily limited by thermal and power constraints.

The benchmark results indicate that the Radeon 860M, despite its integrated nature, achieves performance parity with several discrete GPUs. The database shows deltas of less than 1.1% against all four of its nearest rivals. The Arc Pro B70, with its 230 W TDP, 32 GB of GDDR6, and PCIe 5.0 x16 interface, is built for a different workload profile entirely. Its lack of recorded benchmarks means the database cannot yet confirm how its theoretical advantages translate into real-world scores. The specification sheet suggests a large win for the Intel card in compute-heavy and memory-bound tasks, but the absence of measurements leaves that as an unverified projection rather than a recorded result.
