Intel Arc B570 vs NVIDIA RTX A4000 Mobile Comparison

Where Each One Wins

The benchmark split between the NVIDIA RTX A4000 Mobile and the Intel Arc B570 is nearly even, with the Intel part taking five of nine head-to-head tests and NVIDIA taking four. That narrow margin, however, masks a clear thematic divide: NVIDIA dominates legacy DirectX workloads and raw OpenCL throughput, while Intel rules the modern API landscape and compute-oriented tasks.

The RTX A4000 Mobile’s biggest win comes in Geekbench OpenCL, where it scores 97,178 against the Arc B570’s 83,514 — a 16.4% advantage. That gap is substantial and suggests NVIDIA’s Ampere architecture retains a significant edge in general-purpose compute as measured by OpenCL. The A4000 also wins decisively in DirectX 10 with a 61.5% lead (105 vs 65), and it holds a smaller but meaningful 7.6% edge in DirectX 11 (127 vs 118). In PassMark G3D, the A4000 posts 14,796 versus 14,195 for the Arc B570, a 4.2% win that reflects overall 3D graphics performance in that suite.

The Arc B570’s victories are concentrated in the newer and more specialized tests. Its largest margin is in Geekbench Vulkan, where it scores 96,844 against 73,002 — a 24.6% swing in Intel’s favor. That is a massive delta and indicates the Xe2-HPG architecture handles Vulkan far more efficiently than NVIDIA’s mobile Ampere part. The Arc B570 also wins PassMark GPU Compute by 12.2% (7,281 vs 6,394), DirectX 12 by 8.3% (72 vs 66), DirectX 9 by 4.3% (164 vs 157), and G2D by 11.5% (661 vs 585).

The use-case split is therefore straightforward: if your workload is legacy DirectX or OpenCL-centric, the RTX A4000 Mobile is the stronger option. If you are targeting Vulkan, DirectX 12, or raw compute throughput, the Arc B570 pulls ahead. PassMark G3D, the closest overall 3D indicator, shows only a 4.2% difference, meaning in mixed real-world gaming the two are near-parity despite their architectural differences.

Architecture Differences

The two GPUs come from entirely different design philosophies and process nodes. The RTX A4000 Mobile uses NVIDIA’s GA104 chip on the Ampere architecture, built on Samsung’s 8 nm process. The die measures 392 mm² and packs 17,400 million transistors, yielding a transistor density of 44.4 million per mm². The Arc B570, in contrast, uses Intel’s BMG-G21 chip on the Xe2-HPG architecture, fabricated by TSMC on a 5 nm process. Its die is smaller at 272 mm² but holds more transistors — 19,600 million — resulting in a far higher density of 72.1 million per mm².

Clock speeds tell a different story. The A4000 Mobile runs at a base of 1140 MHz and boosts to 1680 MHz, while the Arc B570 operates at a flat 2500 MHz for both base and boost. That massive clock advantage helps Intel compensate for its lower raw shader count. The A4000 Mobile has 5,120 shading units, 160 TMUs, and 80 ROPs. The Arc B570 has only 2,304 shading units, 144 TMUs, and 80 ROPs. Despite having fewer than half the shading units, the Arc B570’s higher clocks allow it to stay competitive in many tests.

Ray tracing hardware differs significantly. The A4000 Mobile carries 40 RT cores and 160 tensor cores, while the Arc B570 has 18 RT cores and no tensor core count listed. NVIDIA’s tensor cores give it a clear advantage in AI-accelerated workloads, though the benchmark data does not directly measure that. Memory configurations also diverge: the A4000 Mobile uses 8 GB of GDDR6 on a 256-bit bus, delivering 384.0 GB/s of bandwidth. The Arc B570 offers 10 GB of GDDR6 on a narrower 160-bit bus, achieving 380.0 GB/s — nearly identical bandwidth despite the narrower interface, thanks to faster 19 Gbps effective memory clocks versus 12 Gbps on the NVIDIA part.

Power and physical design separate them further. The A4000 Mobile is a 115 W mobile part with no power connectors, designed for portable devices. The Arc B570 is a 150 W desktop dual-slot card requiring a single 8-pin connector and a 450 W suggested PSU. The A4000 Mobile uses a PCIe 4.0 x16 interface, while the Arc B570 uses PCIe 4.0 x8. Display outputs also differ: the NVIDIA part is portable-device dependent, whereas the Intel card offers 1x HDMI 2.1a and 3x DisplayPort 2.1.

Head-to-Head Benchmarks

The Geekbench Vulkan test delivers the single largest performance gap between these two GPUs. Intel’s Arc B570 scores 96,844, crushing the RTX A4000 Mobile’s 73,002. That 24.6% margin is the kind of result that redefines how these cards should be positioned — for any Vulkan-centric application, the Arc B570 is the clear choice.

The Geekbench OpenCL test flips the script just as decisively. The A4000 Mobile posts 97,178 against the Arc B570’s 83,514, a 16.4% NVIDIA win. Given that both GPUs are competing in the same aggregate performance tier, a swing of this magnitude in either direction shows how workload-specific these architectures truly are.

Legacy DirectX support heavily favors NVIDIA. In PassMark DirectX 10, the A4000 Mobile scores 105 versus 65 for the Arc B570, a 61.5% blowout. DirectX 11 tells a similar but milder story: 127 vs 118, a 7.6% edge for the mobile NVIDIA part. These results indicate that older game engines and compatibility-focused applications will run noticeably better on the A4000 Mobile.

Modern DirectX reverses the trend. The Arc B570 wins DirectX 12 with 72 points against 66, an 8.3% margin. DirectX 9 also goes to Intel, with 164 vs 157, a 4.3% lead. The pattern is consistent: Intel’s Xe2-HPG architecture has been tuned for current-generation APIs, while NVIDIA’s Ampere still excels in the older fixed-function pipeline tests.

Compute workloads are split as well. PassMark GPU Compute goes to the Arc B570 at 7,281 versus 6,394, a 12.2% advantage. This aligns with the Arc B570’s higher FP16 throughput of 23.04 TFLOPS (2:1) versus the A4000 Mobile’s 17.20 TFLOPS (1:1). However, in FP32, the A4000 Mobile leads with 17.20 TFLOPS against 11.52 TFLOPS, which helps explain its OpenCL victory.

The 2D graphics test also favors Intel. The Arc B570 scores 661 in PassMark G2D versus 585 for the A4000 Mobile, an 11.5% margin. This may reflect the Intel card’s higher pixel rate of 200.0 GPixel/s versus 134.4 GPixel/s on the NVIDIA part, as well as its faster memory clock.

The closest overall indicator is PassMark G3D, where the A4000 Mobile wins 14,796 to 14,195, a 4.2% difference. That test, which aggregates 3D rendering performance across multiple scenarios, suggests that in a typical gaming workload these two are nearly interchangeable. The Arc B570’s higher texture rate of 360.0 GTexel/s versus 268.8 GTexel/s helps close the gap, while the A4000 Mobile’s superior FP32 and larger shader count keep it ahead.

Final tally: the Arc B570 wins five head-to-head tests, the A4000 Mobile wins four. The aggregate average benchmark score, however, sits with NVIDIA at 21,379 versus 20,556 — a 4.0% difference. The A4000 Mobile also edges out the Arc B570 in percentile ranking, 66th versus 65th. For buyers prioritizing modern APIs and compute, the Arc B570 is the data-backed pick; for legacy compatibility and OpenCL-heavy tasks, the A4000 Mobile holds the advantage.
