Architecture Differences

The two GPUs represent entirely different architectural generations and design philosophies. The NVIDIA GeForce RTX 3070 Ti Mobile is built on the Ampere architecture using the GA104 chip, fabricated on an 8 nm process at Samsung. The Intel Arc B570 uses the Xe2-HPG architecture with the BMG-G21 chip, fabricated on a 5 nm process at TSMC. This process node difference is substantial: the Intel chip is built on a more advanced node, which helps explain the transistor density gap. The NVIDIA chip holds 17,400 million transistors on a 392 mm² die, for a density of 44.4 million transistors per square millimeter. The Intel chip holds 19,600 million transistors on a much smaller 272 mm² die, yielding a density of 72.1 million transistors per square millimeter.

The compute resource allocation differs sharply. The NVIDIA GPU features 5,888 shading units, 184 texture mapping units, and 96 ROPs. The Intel GPU has 2,304 shading units, 144 TMUs, and 80 ROPs. Despite having fewer shading units, the Intel card achieves a higher pixel rate (200.0 GPixel/s versus 135.4 GPixel/s) and a higher texture rate (360.0 GTexel/s versus 259.4 GTexel/s), a result of its much higher clock speeds. The NVIDIA card runs at a 915 MHz base and 1410 MHz boost, while the Intel card runs at a fixed 2500 MHz for both base and boost.

Ray tracing and AI acceleration also differ. The NVIDIA card includes 46 RT cores and 184 tensor cores. The Intel card includes 18 RT cores and no listed tensor cores. This is a major structural difference, suggesting NVIDIA dedicates more silicon to dedicated acceleration blocks. The FP16 capability also diverges: NVIDIA delivers 16.60 TFLOPS FP16 with a 1:1 ratio to FP32, while Intel delivers 23.04 TFLOPS FP16 with a 2:1 ratio. Intel's FP32 throughput is 11.52 TFLOPS, lower than NVIDIA's 16.60 TFLOPS.

Other feature differences include the bus interface. The NVIDIA card uses PCIe 4.0 x16, while the Intel card uses PCIe 4.0 x8. The power delivery also differs: the NVIDIA mobile part draws 115 W with no power connectors listed, while the Intel card draws 150 W and requires a single 8-pin connector with a suggested 450 W PSU. The Intel card is a dual-slot design measuring 272 mm in length and 115 mm in height, with display outputs of 1x HDMI 2.1a and 3x DisplayPort 2.1. The NVIDIA card's display outputs are listed as portable device dependent.

Head-to-Head Benchmarks

The recorded data shows a clear pattern across the ten benchmark tests: the NVIDIA GeForce RTX 3070 Ti Mobile wins nine of them, while the Intel Arc B570 wins just one. The single Intel victory comes in the 3DMark Steel Nomad DX12 test, where it scores 2,649 against NVIDIA's 2,572, a 2.9% margin. This is notable because it is a modern DirectX 12 workload, suggesting the Xe2-HPG architecture handles that specific test efficiently.

The NVIDIA card's largest win is in the PassMark DirectX 10 test, where it scores 124 versus Intel's 65, a 90.8% advantage. This is an older API test, and the NVIDIA architecture appears far more optimized for it. The second-largest margin is in Geekbench OpenCL, with NVIDIA scoring 106,022 against Intel's 83,514, a 27% lead. That result indicates significantly stronger raw compute throughput, consistent with the higher FP32 figure.

The PassMark DirectX 11 test also favors NVIDIA, scoring 153 versus 118, a 29.7% margin. The PassMark G3D test shows NVIDIA at 17,727 against Intel's 14,195, a 24.9% lead. The PassMark DirectX 9 test gives NVIDIA a 19.5% advantage (196 versus 164). The PassMark G2D test shows NVIDIA at 783 versus 661, an 18.5% margin. The remaining wins are narrower: PassMark DirectX 12 (73 versus 72, 1.4%) and PassMark GPU Compute (7,504 versus 7,281, 3.1%). The Geekbench Vulkan test shows NVIDIA at 100,027 versus Intel's 96,844, a 3.3% margin.

The overall win count is lopsided at 9 to 1 in NVIDIA's favor. However, the magnitude of the wins matters. The Intel card is competitive in the newest DirectX 12 test and in Vulkan, but it loses badly in older DirectX APIs and in OpenCL compute.

Specification Differences

The two GPUs differ across nearly every core specification. The process node differs: NVIDIA uses 8 nm from Samsung, Intel uses 5 nm from TSMC. Transistor count differs: NVIDIA has 17,400 million, Intel has 19,600 million. Die size differs significantly: NVIDIA is 392 mm², Intel is 272 mm². Transistor density follows: NVIDIA is 44.4M per mm², Intel is 72.1M per mm².

Clock speeds are very different. NVIDIA's base clock is 915 MHz and boost is 1410 MHz. Intel's base and boost are both 2500 MHz. Memory clock also differs: NVIDIA runs at 1750 MHz with 14 Gbps effective, Intel runs at 2375 MHz with 19 Gbps effective.

Memory configuration differs: NVIDIA has 8 GB GDDR6 on a 256-bit bus with 448.0 GB/s bandwidth; Intel has 10 GB GDDR6 on a 160-bit bus with 380.0 GB/s bandwidth. The NVIDIA card has more memory bandwidth despite having less capacity and a narrower bus, because its bus width is wider.

Core counts differ in every category. NVIDIA has 5,888 shading units, 184 TMUs, and 96 ROPs. Intel has 2,304 shading units, 144 TMUs, and 80 ROPs. RT core counts differ: NVIDIA has 46, Intel has 18.

Release dates: NVIDIA January 2022, Intel January 2025.

Where Each One Wins

The NVIDIA GeForce RTX 3070 Ti Mobile wins in legacy API workloads. Its PassMark DirectX 10 score is 90.8% higher, DirectX 11 is 29.7% higher, and DirectX 9 is 19.5% higher. It also wins in general rasterization performance, as shown by the PassMark G3D result (24.9% higher) and the PassMark G2D result (18.5% higher). It wins in compute-heavy workloads, with a 27% lead in Geekbench OpenCL and a 3.1% lead in PassMark GPU Compute. It also holds a 3.3% edge in Geekbench Vulkan.

The Intel Arc B570 wins in the 3DMark Steel Nomad DX12 test, scoring 2.9% higher. This is the only recorded benchmark where Intel takes the lead. It also has the advantage of a more modern process node, higher clock speeds, and higher pixel and texture fill rates. The Intel card has more memory capacity (10 GB versus 8 GB) and a higher FP16 throughput (23.04 TFLOPS versus 16.60 TFLOPS), though FP16 performance is typically less relevant for gaming workloads.

The data suggests NVIDIA remains the stronger choice for applications relying on older DirectX versions, OpenCL compute, and general 3D rendering. The Intel card shows promise in a specific modern DX12 test and offers superior fill rates, but the overall benchmark evidence does not support a broad performance advantage.

The Verdict

Based strictly on the recorded benchmark data, the NVIDIA GeForce RTX 3070 Ti Mobile is the faster GPU overall. It wins nine of ten head-to-head tests and holds a higher average benchmark score (23,518 versus 20,556). Its percentile ranking is also higher, at 69 versus Intel's 65. The NVIDIA card's nearest rival, the RTX 3080 Mobile, is only 0.5% ahead, placing it in very competitive company. The Intel Arc B570's nearest rival, the RTX 3070 Mobile, is only 0.1% behind, which shows the Intel card is itself competitive within its own tier.

The Intel Arc B570 does have a clear niche. Its win in 3DMark Steel Nomad DX12 indicates that in a modern DirectX 12 workload, it can outperform the NVIDIA mobile GPU. It also offers higher memory capacity, a newer process node, and higher fill rates. For users running that specific class of workload, the Intel card has a measurable edge.

However, for broad compatibility across older APIs and compute tasks, the NVIDIA card is the safer pick. Its dominant DirectX 10 and DirectX 11 results, along with its substantial OpenCL lead, make it more versatile. The NVIDIA card also has a better average benchmark score by 14.4% (23,518 versus 20,556). The Intel card is active and newer, but the data does not show it overtaking the NVIDIA part in the majority of tests. Users prioritizing raw compute, legacy API support, and overall benchmark averages should favor the NVIDIA GeForce RTX 3070 Ti Mobile. Users focused on the specific Steel Nomad DX12 workload or needing more memory capacity should consider the Intel Arc B570. The launch MSRP for the Intel Arc B570 is 219 USD.
