Intel Arc Pro B70 vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

Intel Arc Pro B70 vs NVIDIA GeForce RTX 5070 Ti Mobile is a comparison between a workstation-class desktop accelerator and a mobile gaming GPU. The Arc Pro B70 targets professional workloads with a large memory pool, while the RTX 5070 Ti Mobile is a power-sipping laptop part with a higher benchmark percentile. The recorded data shows a clear split: the RTX 5070 Ti Mobile dominates in compute and graphics test scores, but the Arc Pro B70 counters with superior raw throughput metrics in pixel, texture, and memory bandwidth.

Head-to-Head Benchmarks

The RTX 5070 Ti Mobile has a full suite of benchmark scores in the database, while the Arc Pro B70 has no recorded benchmark entries. This makes direct score comparisons one-sided, but the available numbers for the NVIDIA part define its standing against nearby rivals. The GeForce RTX 5070 Ti Mobile posts an average benchmark score of 35435 across nine tests. Its percentile versus all GPUs is 80, placing it well above the Arc Pro B70's percentile of 50, which is based on no actual benchmark data but instead on its listed specifications.

In the individual benchmark results, the RTX 5070 Ti Mobile scores 143870 in Geekbench OpenCL and 139213 in Geekbench Vulkan. These are the two highest recorded scores for the mobile GPU. The Passmark suite shows a G3D score of 24004, a G2D score of 981, and a GPU compute score of 10101. The older DirectX tests produce lower results: 259 in DirectX 9, 237 in DirectX 11, 151 in DirectX 10, and 102 in DirectX 12. The average of these nine scores, 35435, sits within 2.4% of its nearest rivals. The NVIDIA Quadro GV100 averages 35520, which is 0.2% higher. The AMD Radeon Pro Duo averages 35860, 1.2% higher. The NVIDIA T1000 averages 36289, 2.4% higher. The NVIDIA A2 averages 34690, which is 2.1% lower than the RTX 5070 Ti Mobile. These delta values show the mobile GPU performing within a tight band of professional cards, with no rival exceeding it by more than 2.4% or falling behind by more than 2.1%.

Without direct head-to-head benchmarks, the Arc Pro B70 cannot be scored against the RTX 5070 Ti Mobile in the same tests. The wins tally is zero for each product. The only numerical comparison available comes from specifications. The Arc Pro B70 lists a pixel rate of 358.4 GPixel/s versus 115.8 GPixel/s for the mobile NVIDIA part, a 3.1 times advantage. The texture rate is 716.8 GTexel/s versus 266.2 GTexel/s, a 2.7 times advantage. The Arc Pro B70 also leads in FP32 throughput at 22.94 TFLOPS versus 17.04 TFLOPS, a 34.6% margin. The memory bandwidth favors the Arc Pro B70 at 608.0 GB/s versus 672.0 GB/s for the RTX 5070 Ti Mobile, which is a 10.5% deficit for the Intel card. These are theoretical peak rates, not measured test scores, but they represent the only recorded quantitative comparison.

Architecture Differences

The two GPUs use different architectures and physical designs. The Intel Arc Pro B70 is built on the Battlemage generation with the Xe2-HPG architecture, using the BMG-G31 chip. The NVIDIA GeForce RTX 5070 Ti Mobile uses the Blackwell 2.0 architecture with the GB205 chip, part of the GeForce 50 Mobile generation. Both are fabricated on a 5 nm process at TSMC, but the die sizes differ. The Arc Pro B70 has a die size of 368 mm², while the RTX 5070 Ti Mobile measures 263 mm². The transistor count for the Intel part is unknown, while the NVIDIA chip packs 31,100 million transistors, yielding a transistor density of 118.3M per mm².

The memory subsystems diverge sharply. The Arc Pro B70 carries 32 GB of GDDR6 on a 256-bit bus, producing 608.0 GB/s of bandwidth. The RTX 5070 Ti Mobile has 12 GB of GDDR7 on a 192-bit bus, reaching 672.0 GB/s. The memory clock differs as well: 2375 MHz with 19 Gbps effective for the Intel card, versus 1750 MHz with 28 Gbps effective for the NVIDIA part. The GDDR7 standard enables higher effective data rates despite a narrower bus.

Compute unit counts favor different aspects. The Arc Pro B70 has 4096 shading units, 256 texture mapping units, and 128 render output units. It also includes 32 ray tracing cores. The RTX 5070 Ti Mobile has 5888 shading units, 184 TMUs, and 80 ROPs, plus 46 RT cores and 184 tensor cores. The Intel card lacks tensor cores entirely. The FP16 throughput for the Arc Pro B70 is 45.88 TFLOPS with a 2:1 ratio against FP32, while the RTX 5070 Ti Mobile delivers 17.04 TFLOPS at a 1:1 ratio. The NVIDIA part's tensor cores are present but not quantified in the data beyond their count.

Clock speeds show a large gap. The Arc Pro B70 runs at a base clock of 2280 MHz and a boost of 2800 MHz. The RTX 5070 Ti Mobile operates at a base of 847 MHz and a boost of 1447 MHz. This explains part of the performance difference in raw throughput, as the Intel card relies on high clocks and a larger die, while the NVIDIA mobile part is constrained to a 60 W thermal design power. The Arc Pro B70 has a TDP of 230 W, a dual-slot cooler, and requires a single 8-pin power connector with a suggested PSU of 550 W. The RTX 5070 Ti Mobile is an integrated GPU package with no power connectors and a 60 W TDP.

Physical dimensions reflect the desktop versus mobile split. The Arc Pro B70 measures 267 mm in length, 110 mm in height, and 39 mm in width. The RTX 5070 Ti Mobile has no recorded dimensions, as it is designed for portable devices. The Intel card uses a PCIe 5.0 x16 interface, as does the NVIDIA part. Display outputs differ: the Arc Pro B70 offers 1x HDMI 2.1a and 3x DisplayPort 2.1, while the RTX 5070 Ti Mobile's outputs are listed as portable device dependent. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The RTX 5070 Ti Mobile wins in measured benchmark performance. Its average score of 35435 and 80th percentile indicate strong real-world results across compute and graphics tests. The Geekbench scores of 143870 in OpenCL and 139213 in Vulkan show particularly high compute throughput. The Passmark G3D score of 24004 confirms solid rasterization performance. The recorded data places it within 2.4% of professional workstation cards like the Quadro GV100 and Radeon Pro Duo, meaning it trades blows with much larger desktop parts.

The Arc Pro B70 wins in theoretical peak throughput metrics. Its pixel rate of 358.4 GPixel/s is more than triple the RTX 5070 Ti Mobile's 115.8 GPixel/s. Its texture rate of 716.8 GTexel/s nearly triples the NVIDIA part's 266.2 GTexel/s. The FP32 output of 22.94 TFLOPS is 34.6% higher than 17.04 TFLOPS. The memory capacity of 32 GB dwarfs the 12 GB on the mobile GPU, which is critical for large datasets. The Arc Pro B70 also has a higher boost clock of 2800 MHz versus 1447 MHz, and a wider 256-bit memory bus versus 192-bit.

The RTX 5070 Ti Mobile counters with higher memory bandwidth at 672.0 GB/s versus 608.0 GB/s, despite having half the memory capacity. It also has more shading units (5888 versus 4096) and more RT cores (46 versus 32). The tensor cores on the NVIDIA part are absent from the Intel specification, giving the mobile GPU a feature advantage for AI workloads, though no benchmark data exists for either part in that domain.

The Verdict

The data shows two products serving different roles. The NVIDIA GeForce RTX 5070 Ti Mobile has actual benchmark scores and an 80th percentile ranking, making it the only one of the pair with validated performance measurements. Its average score of 35435 and its proximity to rivals like the Quadro GV100 (0.2% slower) and T1000 (2.4% slower) indicate a capable performer for mobile systems. The 60 W TDP and integrated form factor make it suitable for laptops where power and space are limited.

The Intel Arc Pro B70 has no benchmark scores, so its performance cannot be confirmed from the database. Its specifications suggest high peak throughput in pixel fill, texture fill, and FP32 compute, along with 32 GB of memory. The 230 W TDP and dual-slot cooler require a desktop chassis with a 550 W PSU. Its release date is 2026-03-25, over a year after the RTX 5070 Ti Mobile's 2025-02-28 launch. The Arc Pro B70 has a launch MSRP of 949 USD.

For users who need measured performance, the RTX 5070 Ti Mobile is the only option with recorded scores. For those who require maximum memory capacity or peak theoretical fill rates, the Arc Pro B70 presents higher specification numbers. The RTX 5070 Ti Mobile's 80th percentile versus the Arc Pro B70's 50th percentile suggests the NVIDIA part is better positioned in the overall GPU landscape, but that percentile for the Intel card is derived from unverified specs, not tests. The choice comes down to validated benchmark results versus unverified peak specifications.
