AMD Radeon 860M vs Intel Arc B370 Comparison

The Verdict

The benchmark data presents a stark contrast between these two integrated graphics processors. The AMD Radeon 860M, with an average benchmark score of 26401, sits in the 72nd percentile of all GPUs, placing it in a completely different performance class than the Intel Arc B370, which records an average score of 1184 and sits in the 5th percentile. The Radeon 860M's recorded scores in Geekbench OpenCL (22759) and Geekbench Vulkan (30043) are roughly an order of magnitude higher than the Arc B370's single recorded 3DMark Steel Nomad DX12 score of 1184.

The Radeon 860M's nearest rivals in the database include the NVIDIA GeForce MX550 (average score 26421, a 0.1% difference), the NVIDIA GeForce RTX 5060 (average score 26331, a 0.3% difference), and the AMD Radeon RX 5700 XT 50th Anniversary (average score 26553, a 0.6% difference). This places it in the company of dedicated discrete graphics solutions. The Arc B370's nearest rivals are much older parts: the ATI Mobility Radeon HD 5570 (average score 1186, a 0.2% difference), the ATI Radeon HD 5770 (average score 1190, a 0.5% difference), and the AMD Radeon HD 7650M (average score 1192, a 0.7% difference). The data shows that the Radeon 860M is the clear choice for any workload requiring meaningful graphics performance, while the Arc B370 appears positioned for basic display output and low-demand tasks. Systems requiring the former should be equipped with the AMD part; systems where only minimal graphics acceleration is needed could use the Intel part, but the performance gap is so substantial that the Radeon 860M is the only defensible option for general use.

Architecture Differences

The two processors come from different manufacturers and use entirely different architectures. The AMD Radeon 860M is built on the RDNA 3.5 architecture, using a chip codenamed Krackan Point, and belongs to the Navi III IGP generation (Strix Point Mobile). The Intel Arc B370 uses the Xe3-LPG architecture, built on a chip codenamed Panther Lake, and belongs to the Arc Graphics-M generation (Panther Lake).

The manufacturing processes differ substantially. The AMD part is fabricated on a 4 nm process at TSMC, while the Intel part uses a 3 nm process at Intel's own foundry. Both have unknown transistor counts and die sizes in the database. The Radeon 860M uses a PCIe 4.0 x8 bus interface, while the Arc B370's bus interface is listed simply as IGP.

The compute resources are configured differently. The AMD Radeon 860M has 512 shading units, 32 texture mapping units, and 16 render output units, along with 8 ray tracing cores. The Intel Arc B370 has 1280 shading units, 40 texture mapping units, and 20 render output units, along with 10 ray tracing cores. Despite having more of nearly every execution resource, the Arc B370's overall throughput is far lower.

The FP32 compute figures reflect this oddity. The Radeon 860M delivers 3.072 TFLOPS of FP32 performance, while the Arc B370 delivers 6.144 TFLOPS. In FP16, the Radeon 860M delivers 3.072 TFLOPS with a 1:1 ratio, while the Arc B370 delivers 12.29 TFLOPS with a 2:1 ratio. The Arc B370's theoretical compute capability is higher, yet its real-world benchmark scores are dramatically lower, which indicates that theoretical peak throughput does not translate into measurable performance in this case.

Both parts are IGPs with no power connectors, and both have display outputs described as Portable Device Dependent. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so there is no API feature gap. The release dates differ, with the Radeon 860M appearing in the database with a release date of 2025-02-28, while the Arc B370 has a release date of 2026-01-26. The Radeon 860M lists a predecessor as Navi II IGP, while the Arc B370 has no predecessor listed.

Neither has a launch MSRP recorded, and both are listed as Active in production status.

Head-to-Head Benchmarks

Direct head-to-head benchmark results are not recorded in the database, so the comparison relies on each part's individual benchmark suite. The AMD Radeon 860M has two recorded Geekbench results. In Geekbench OpenCL, it scores 22759. In Geekbench Vulkan, it scores 30043. The Intel Arc B370 has a single recorded result in 3DMark Steel Nomad DX12, scoring 1184.

The Radeon 860M's Vulkan score of 30043 is more than 25 times the Arc B370's DX12 score. Even the Radeon 860M's lower OpenCL score of 22759 is roughly 19 times higher than the Arc B370's result. The two benchmarks are different tests, so direct comparison is not perfectly apples-to-apples, but the magnitude of the gap is overwhelming.

The average benchmark score for the Radeon 860M is 26401, which is 25217 points higher than the Arc B370's average of 1184. In percentage terms, the Radeon 860M's average is approximately 22 times the Arc B370's average. The percentile rankings reinforce this: the Radeon 860M sits in the 72nd percentile of all GPUs, while the Arc B370 is in the 5th percentile.

Looking at the nearest rivals provides additional context. The Radeon 860M's closest competitor, the NVIDIA GeForce MX550, scores 26421, which is only 0.1% higher. The RTX 5060 scores 26331, which is 0.3% lower. The Radeon 860M is essentially performance-equivalent to these discrete GPUs. The Arc B370's closest competitor, the ATI Mobility Radeon HD 5570, scores 1186, which is 0.2% higher. The ATI Radeon HD 5770 scores 1190, 0.5% higher, and the AMD Radeon HD 7650M scores 1192, 0.7% higher. The Arc B370 is clustered with GPU designs from a much older era.

Where Each One Wins

The AMD Radeon 860M wins in every recorded benchmark category. Its Geekbench OpenCL score of 22759 and Geekbench Vulkan score of 30043 demonstrate strong performance in both compute and graphics API workloads. The average benchmark score of 26401 places it in the same performance band as the NVIDIA GeForce MX550 and the NVIDIA GeForce RTX 5060, both of which are discrete graphics solutions. The 72nd percentile ranking confirms that this IGP outperforms the majority of all GPUs in the database.

The Intel Arc B370's single recorded benchmark, a 3DMark Steel Nomad DX12 score of 1184, places it in the 5th percentile. Its nearest rivals are the ATI Mobility Radeon HD 5570 and ATI Radeon HD 5770, both of which are legacy parts. The Arc B370's higher shading unit count (1280 vs. 512), higher TMU count (40 vs. 32), higher ROP count (20 vs. 16), and higher FP32 throughput (6.144 TFLOPS vs. 3.072 TFLOPS) do not translate into superior measured performance. The data shows that the Arc B370's theoretical specifications vastly exceed its actual benchmark results.

For use cases such as general desktop acceleration, video playback, or lightweight productivity, the Arc B370 could theoretically suffice, but the recorded data does not support any performance advantage. The Radeon 860M is the clear winner for any workload that stresses the GPU: compute tasks, gaming, or graphics rendering. The Arc B370's lower power envelope of 25 W compared to the Radeon 860M's 15 W is not an advantage either, as it consumes more power while delivering far less performance. In every measurable way, the AMD Radeon 860M is the superior part, and the Intel Arc B370's only distinguishing feature is its substantially lower performance ceiling.
