Intel Arc B570 vs NVIDIA GeForce RTX 4050 Mobile Comparison

Intel Arc B570 vs NVIDIA GeForce RTX 4050 Mobile is a clash between desktop expansion and mobile integration, and the data splits the two cleanly by workload. The Intel Arc B570 takes the overall average benchmark crown with a score of 20,556 against the RTX 4050 Mobile’s 19,049, a lead of roughly 7.9% that is driven almost entirely by compute and next-generation API performance. However, the NVIDIA part fights back in legacy DirectX tests and narrowly edges out the Intel card in the Passmark G3D metric, proving that raw architectural advantages do not always translate to every benchmark. The verdict from the data: the Arc B570 is the stronger compute and modern-API performer, while the RTX 4050 Mobile holds its own in older DirectX titles and offers a more power-efficient mobile form factor.

The Verdict

Choose the Intel Arc B570 if your priority is raw compute throughput and modern DirectX 12 performance. The data shows it wins 5 of 9 head-to-head benchmarks, including a dominant 28.7% lead in Geekbench Vulkan (96,844 vs 75,235) and a 22.4% advantage in Passmark GPU Compute (7,281 vs 5,947). For users running compute-heavy workloads or Vulkan-based applications, the Arc B570 is the clear choice, also posting an 11.7% win in Geekbench OpenCL (83,514 vs 74,748). Its average benchmark score of 20,556 places it in the 65th percentile of all GPUs, which is higher than the RTX 4050 Mobile’s 63rd percentile.

Choose the NVIDIA GeForce RTX 4050 Mobile if you need a low-power, integrated solution for laptops and prioritize legacy DirectX compatibility. The RTX 4050 Mobile wins 4 of 9 benchmarks, notably taking Passmark DirectX 10 (79 vs 65, a 17.7% lead), DirectX 11 (130 vs 118, a 9.2% lead), and DirectX 9 (184 vs 164, a 10.9% lead). Its 50 W TDP and IGP slot width make it fundamentally different from the Arc B570’s 150 W dual-slot desktop design, which requires a 450 W PSU and an 8-pin power connector. The mobile part also edges out the Arc B570 in Passmark G3D (14,423 vs 14,195, a 1.6% lead), showing that for general 3D rendering, the NVIDIA card is marginally ahead.

For gaming specifically, the data is mixed but slightly favors NVIDIA. The RTX 4050 Mobile wins the Passmark G3D test, which is the closest proxy to overall gaming performance, but the Arc B570 counters with an 18% lead in Passmark DirectX 12 (72 vs 61). If you play modern DX12 titles, the Arc B570 is better; if you play older DX9/10/11 games, the RTX 4050 Mobile has the edge. The Arc B570 also wins Passmark G2D (661 vs 633, a 4.4% lead), indicating better 2D performance for desktop tasks.

Architecture Differences

The two GPUs come from entirely different design philosophies. The Intel Arc B570 uses the BMG-G21 chip built on TSMC’s 5 nm process, featuring 19,600 million transistors on a 272 mm² die with a transistor density of 72.1 million per mm². It is based on the Xe2-HPG architecture, part of the Battlemage generation (Arc 5 series). In contrast, the NVIDIA GeForce RTX 4050 Mobile uses the AD107 chip on the same TSMC 5 nm node, but packs 18,900 million transistors into a much smaller 159 mm² die, achieving a higher density of 118.9 million per mm². This makes the NVIDIA chip more compact and efficient per area, but the Intel chip has more raw silicon.

Core counts differ significantly. The Arc B570 has 2,304 shading units, 144 texture mapping units (TMUs), and 80 raster output units (ROPs), while the RTX 4050 Mobile has 2,560 shading units, 80 TMUs, and 48 ROPs. Despite having more shading units, the NVIDIA part has fewer TMUs and ROPs, which explains its lower texture and pixel rates. The Arc B570 also has 18 ray tracing cores, while the RTX 4050 Mobile has 20, plus 80 tensor cores that the Intel card lacks entirely.

Memory architecture is a major differentiator. The Arc B570 comes with 10 GB of GDDR6 on a 160-bit bus, delivering 380.0 GB/s of bandwidth. The RTX 4050 Mobile has only 6 GB of GDDR6 on a 96-bit bus, with 192.0 GB/s of bandwidth—exactly half the Intel card’s throughput. Clock speeds tell a similar story: the Arc B570 runs at a flat 2500 MHz base and boost, while the RTX 4050 Mobile runs at 1455 MHz base and 1755 MHz boost. Memory clocks differ too, with the Arc at 2375 MHz (19 Gbps effective) and the RTX at 2000 MHz (16 Gbps effective).

The power envelope is night and day. The Arc B570 draws 150 W, requires a dual-slot cooler, and needs a 1x 8-pin power connector with a 450 W suggested PSU. The RTX 4050 Mobile is an IGP (integrated graphics processor) with a 50 W TDP, no power connectors, and no PSU requirement, designed for portable devices. Both use PCIe 4.0 x8 interfaces and support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs also differ: the Arc B570 offers 1x HDMI 2.1a and 3x DisplayPort 2.1, while the RTX 4050 Mobile’s outputs are portable-device dependent.

Where Each One Wins

Intel Arc B570 wins in compute and modern graphics APIs. The data shows decisive victories in Geekbench Vulkan (28.7% ahead), Passmark GPU Compute (22.4% ahead), and Geekbench OpenCL (11.7% ahead). These wins are consistent with its higher FP32 throughput of 11.52 TFLOPS versus the RTX 4050 Mobile’s 8.986 TFLOPS, and its FP16 performance of 23.04 TFLOPS (2:1 ratio) versus the NVIDIA part’s 8.986 TFLOPS (1:1 ratio). The Arc B570 also wins Passmark DirectX 12 by 18%, aligning with its architectural focus on the latest API. Its 10 GB memory capacity and 380.0 GB/s bandwidth give it a clear advantage in memory-intensive workloads, and its pixel rate of 200.0 GPixel/s and texture rate of 360.0 GTexel/s dwarf the RTX 4050 Mobile’s 84.24 GPixel/s and 140.4 GTexel/s.

NVIDIA GeForce RTX 4050 Mobile wins in legacy DirectX and general 3D rendering. The RTX 4050 Mobile takes Passmark DirectX 9 by 10.9%, DirectX 10 by 17.7%, and DirectX 11 by 9.2%, which are substantial margins for older game engines. It also wins Passmark G3D by 1.6%, despite having lower raw specs, suggesting better driver optimization for traditional 3D workloads. Its 2,560 shading units and 20 RT cores provide a solid foundation, and its higher transistor density (118.9M vs 72.1M per mm²) indicates a more efficient design per square millimeter. The 50 W TDP makes it the only viable choice for thin-and-light laptops, whereas the Arc B570 is strictly a desktop card.

The split is clear: Intel for modern, compute-heavy tasks; NVIDIA for legacy compatibility and mobile integration. The Arc B570’s wins in Vulkan and compute are massive, while the RTX 4050 Mobile’s wins in DX9/10/11 are more modest but consistent. The Passmark G3D result (14,195 vs 14,423) shows that for standard 3D graphics, the NVIDIA part is slightly ahead, making it the safer bet for general gaming without API-specific optimization.

Head-to-Head Benchmarks

The single biggest win for the Intel Arc B570 comes in Geekbench Vulkan, where it scores 96,844 against the RTX 4050 Mobile’s 75,235—a 28.7% delta. This is a massive gap that highlights the Arc B570’s superior Vulkan implementation, likely due to its 380.0 GB/s memory bandwidth and higher clock speeds. The second-largest Intel win is in Passmark GPU Compute, where 7,281 beats 5,947 by 22.4%, reinforcing the compute-heavy nature of the Xe2-HPG architecture. The Arc B570 also takes Geekbench OpenCL with 83,514 versus 74,748 (11.7%) and Passmark DirectX 12 with 72 versus 61 (18%). In Passmark G2D, the Intel card wins 661 to 633, a smaller 4.4% margin.

The NVIDIA GeForce RTX 4050 Mobile’s biggest win is in Passmark DirectX 10, where 79 beats 65 by 17.7%. This is followed by Passmark DirectX 9 (184 vs 164, a 10.9% lead) and Passmark DirectX 11 (130 vs 118, a 9.2% lead). The most competitive result is Passmark G3D, where the RTX 4050 Mobile wins 14,423 to 14,195, a narrow 1.6% margin. This close result in the general 3D test suggests that for most real-world gaming scenarios, the two GPUs are nearly equivalent, with NVIDIA holding a slight edge. The overall win count is 5 for Intel and 4 for NVIDIA, but the average benchmark scores tell a different story: the Arc B570’s 20,556 average is 1,507 points higher than the RTX 4050 Mobile’s 19,049, a 7.9% advantage that reflects the magnitude of Intel’s wins in compute and Vulkan outweighing NVIDIA’s smaller legacy DX wins.
