Intel Arc A770M vs Intel Arc B570 Comparison

Head-to-Head Benchmarks

The recorded data shows a clear overall victory for the Intel Arc B570, which takes 7 of the 10 head-to-head benchmark comparisons. The most decisive margin appears in PassMark’s DirectX 11 test, where the B570 scores 118 against the A770M’s 69, a 71% advantage. This is the single largest delta in the entire comparison and indicates that the newer architecture handles legacy DirectX 11 workloads with substantially more efficiency than the older mobile part.

Compute performance also strongly favors the B570. In PassMark GPU Compute, the B570 records 7281 versus 4778 for the A770M, a 52.4% lead. This is a significant gap for a desktop part that draws more power but delivers over half again as much raw compute throughput in this specific test. The Vulkan benchmark follows a similar pattern: the B570 scores 96844 against 74422, a 30.1% advantage. This suggests the Xe2-HPG architecture has substantially improved its Vulkan driver and hardware scheduling compared to the Xe-HPG design in the A770M.

In the 3DMark Steel Nomad DX12 test, the B570 wins with 2649 points versus 2278, a 16.3% lead. The PassMark G3D test shows a 20.6% advantage (14195 vs 11774), and the DirectX 10 test shows a 16.1% edge (65 vs 56). DirectX 12 performance is nearly tied, with the B570 at 72 and the A770M at 70, a mere 2.9% difference. This near-parity in native DX12 suggests that while the B570 is generally faster, the A770M’s larger memory bus and higher bandwidth keep it competitive in modern API workloads.

The A770M wins three tests, though by smaller margins. In Geekbench OpenCL, the A770M scores 89494 against 83514, a 6.7% lead. This is notable because it contrasts with the B570’s large compute win in PassMark, indicating that the two benchmarks stress different aspects of the hardware or driver stack. The A770M also wins PassMark DirectX 9 (178 vs 164, a 7.9% edge) and PassMark G2D (711 vs 661, a 7% edge). The G2D result is particularly interesting, as the A770M is an integrated mobile part yet outperforms the discrete B570 in 2D graphics work.

Overall, the B570’s average benchmark score of 20556 places it at the 65th percentile of all GPUs, while the A770M’s 18383 lands at the 62nd percentile. The B570 sits within 0.1% of the NVIDIA GeForce RTX 3070 Mobile and Intel Arc A750, while the A770M is within 0.1% of the AMD Radeon RX 460. These percentile positions confirm that the B570 is the stronger performer in aggregate, even though the A770M holds specific advantages in OpenCL and legacy DirectX 9 workloads.

Architecture Differences

The two GPUs represent distinct generations of Intel’s graphics architecture. The B570 uses the BMG-G21 chip built on Xe2-HPG architecture, while the A770M uses the DG2-512 chip on the older Xe-HPG architecture. This generational gap is reflected in the process node: the B570 is fabricated on a 5 nm process at TSMC, whereas the A770M uses a 6 nm process. The B570 packs 19,600 million transistors into a 272 mm² die, yielding a transistor density of 72.1M per mm². The A770M has more transistors at 21,700 million but spreads them across a much larger 406 mm² die, resulting in a lower density of 53.4M per mm². The B570’s smaller, denser die is a direct result of the newer process node.

Clock speeds differ substantially. The B570 runs at a fixed 2500 MHz for both base and boost, while the A770M operates at 1650 MHz base and 2050 MHz boost. The B570’s higher clocks contribute to its performance advantage despite having fewer execution resources. Memory clocks also favor the B570 in terms of effective speed: 2375 MHz (19 Gbps effective) versus 2000 MHz (16 Gbps effective) for the A770M.

The memory configuration tells a different story. The A770M offers 16 GB of GDDR6 on a 256-bit bus, delivering 512.0 GB/s of bandwidth. The B570 offers only 10 GB on a 160-bit bus, yielding 380.0 GB/s. This 34.7% bandwidth deficit for the B570 is partially offset by its higher memory clock, but the A770M’s wider bus gives it a clear advantage in bandwidth-sensitive workloads. The A770M also has more execution resources: 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores, compared to the B570’s 2304 shading units, 144 TMUs, 80 ROPs, and 18 ray tracing cores. Despite having nearly half the shading units, the B570 achieves higher FP32 throughput in the database? No, the data shows the A770M has higher FP32 at 16.79 TFLOPS versus 11.52 TFLOPS for the B570. The B570’s advantage comes from architectural efficiency, not raw resource counts.

Power and packaging differ fundamentally. The B570 is a dual-slot discrete card with a 150 W TDP and a single 8-pin power connector, requiring a 450 W suggested PSU. The A770M is an integrated graphics processor (IGP) with a 120 W TDP and no power connectors, as it draws power through the host system. The B570 connects via PCIe 4.0 x8, while the A770M uses PCIe 4.0 x16. Display outputs also differ: the B570 provides 1x HDMI 2.1a and 3x DisplayPort 2.1, while the A770M’s outputs are portable-device dependent, meaning they vary by laptop implementation.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B570 is marked as Active production status and was released on 2025-01-15, while the A770M is End-of-life with no recorded release date. The B570’s predecessor is Alchemist, which is the architecture family that includes the A770M.

The Verdict

The data indicates that the Intel Arc B570 is the stronger overall performer. Its average benchmark score of 20556 exceeds the A770M’s 18383 by 11.8%. The B570 wins the majority of direct comparisons, including the critical 3DMark Steel Nomad DX12 test, Vulkan, and compute workloads. For users prioritizing modern API performance, particularly Vulkan and compute tasks, the B570 is the clear choice from the recorded measurements.

The A770M retains specific advantages that matter in certain contexts. Its 16 GB memory capacity and 512.0 GB/s bandwidth are far superior to the B570’s 10 GB and 380.0 GB/s. In OpenCL workloads, the A770M leads by 6.7%, and in DirectX 9 legacy titles it wins by 7.9%. The G2D win indicates that the A770M handles 2D graphics tasks more efficiently, which could matter for productivity workloads or multi-monitor setups.

The production status is decisive. The B570 is Active and recently released, while the A770M is End-of-life. The B570 also has a recorded launch MSRP of 219 USD, which can be stated once per the database format. The A770M has no launch MSRP recorded, reflecting its mobile OEM nature. For new system builders, the B570 offers current support and better aggregate performance. For those with existing mobile platforms that already include an A770M, the data shows it remains competitive in specific areas, but it is not the superior part in overall benchmark averages.
