Intel Arc Pro B50 vs NVIDIA GeForce RTX 5070 Mobile Comparison

The database comparison places the Intel Arc Pro B50 against the NVIDIA GeForce RTX 5070 Mobile in a head-to-head that is decisively one-sided. Across the seven recorded benchmark tests, the NVIDIA part secures a clean sweep, with the Intel Arc Pro B50 recording zero wins. The average benchmark score gap is substantial: the RTX 5070 Mobile posts an average of 29,928, while the Arc Pro B50 sits at 2,660. This places the NVIDIA GPU in the 75th percentile of all GPUs, whereas the Intel part lands in the 17th percentile.

The most dramatic single-test difference appears in the PassMark G3D suite. The RTX 5070 Mobile scores 20,355, which is 38.3% higher than the Arc Pro B50's 12,553. This is the largest percentage gap in any of the direct comparisons, indicating a massive advantage in overall 3D rendering throughput. In the legacy DirectX 10 test, the NVIDIA part scores 129 against 58, a 55% deficit for the Intel card, which is the largest relative margin in the entire dataset. The DirectX 11 test shows a similar trend, with the RTX 5070 Mobile at 192 and the Arc Pro B50 at 100, a 47.9% difference.

The compute-oriented results follow the same pattern. In the PassMark GPU Compute test, the NVIDIA GPU scores 8,279, beating the Intel card's 6,037 by 27.1%. The DirectX 12 test shows the smallest percentage gap in the suite, with the RTX 5070 Mobile scoring 93 against 64, a 31.2% lead for NVIDIA. Even in the 2D graphics test, which is often less demanding on raw shader power, the RTX 5070 Mobile wins, scoring 896 versus 717, a 20% advantage.

Head-to-Head Benchmarks

The data shows a consistent pattern of NVIDIA dominance across every API and workload category. The largest win for the RTX 5070 Mobile comes in the DirectX 10 legacy test, where it outperforms the Arc Pro B50 by 55%. This is a significant margin, suggesting that even older DirectX titles, which typically do not stress modern hardware heavily, run substantially faster on the NVIDIA part. The DirectX 11 result is nearly as lopsided, with a 47.9% lead, indicating that the RTX 5070 Mobile's architecture handles the most common gaming API with far greater efficiency.

The DirectX 12 test, which is the modern standard for high-end gaming, shows a narrower but still clear 31.2% advantage for the RTX 5070 Mobile. This narrower gap suggests that the Intel Arc Pro B50's Xe2-HPG architecture is relatively more competitive in newer, more parallel workloads, but it still falls well short of the NVIDIA part. The DirectX 9 test shows a 32.7% lead for NVIDIA, confirming that the gap persists even in older, less demanding scenarios.

The G3D benchmark, which aggregates overall 3D performance, shows a 38.3% difference. This is the headline figure for gaming performance, and it puts the RTX 5070 Mobile in a different performance class. The GPU Compute test, which measures general-purpose compute throughput, shows a 27.1% lead for NVIDIA. This is a smaller margin than the gaming tests, but still a decisive win, indicating that the RTX 5070 Mobile's 144 tensor cores and higher FP32 throughput (13.13 TFLOPS versus 10.65 TFLOPS) provide a real advantage in compute-heavy tasks like rendering or physics simulation.

The 2D test, which is rarely a point of differentiation, still goes to NVIDIA by 20%. This result is notable because it suggests that the RTX 5070 Mobile's higher pixel rate (68.40 GPixel/s versus 41.60 GPixel/s) and higher ROP count (48 versus 16) deliver tangible benefits even in desktop compositing and 2D workloads.

Architecture Differences

The two GPUs come from different architectural lineages, and the recorded specifications explain why the performance gap is so wide. The Intel Arc Pro B50 uses the BMG-G21 chip built on the Xe2-HPG architecture, part of the Battlemage Pro Series. It is fabricated on a 5 nm process at TSMC, with 19,600 million transistors on a 272 mm² die, resulting in a transistor density of 72.1 million per mm². The NVIDIA GeForce RTX 5070 Mobile uses the GB206 chip on the Blackwell 2.0 architecture, also on a 5 nm TSMC process, but with 21,900 million transistors on a smaller 181 mm² die, yielding a much higher density of 121.0 million per mm².

The core configurations diverge sharply. The RTX 5070 Mobile carries 4,608 shading units, 144 texture mapping units, and 48 ROPs. The Arc Pro B50 has 2,048 shading units, 128 TMUs, and only 16 ROPs. The NVIDIA part also fields 36 RT cores and 144 tensor cores, while the Intel card has 16 RT cores and no dedicated tensor cores listed. This hardware disparity directly explains the compute and rasterization performance gap. The RTX 5070 Mobile's FP32 throughput is 13.13 TFLOPS, compared to 10.65 TFLOPS for the Arc Pro B50. The FP16 figures are also telling: NVIDIA runs at 13.13 TFLOPS in a 1:1 ratio, while Intel reaches 21.30 TFLOPS using a 2:1 ratio, which is less efficient for general compute.

Memory configurations also favor the NVIDIA part. The RTX 5070 Mobile uses 8 GB of GDDR7 memory on a 128-bit bus, delivering 384.0 GB/s of bandwidth. The Arc Pro B50 has 16 GB of GDDR6 on the same 128-bit bus, but bandwidth drops to 224.0 GB/s. The NVIDIA memory is faster by a wide margin, and the higher bandwidth is critical for high-resolution textures and data-intensive workloads. Clock speeds tell a different story: the Intel card runs at a base of 1700 MHz and boosts to 2600 MHz, while the NVIDIA part operates at a base of 907 MHz and boosts to only 1425 MHz. Despite the lower clocks, the RTX 5070 Mobile wins decisively, confirming that its architectural efficiency and wider execution resources outweigh the raw clock advantage of the Intel part.

The power profiles are also distinct. The Arc Pro B50 has a TDP of 70 W, while the RTX 5070 Mobile consumes only 50 W. This is a notable inversion: the slower, lower-scoring Intel card draws more power, while the faster NVIDIA part is more power-efficient. The Intel card is a dual-slot design with no power connectors and a suggested PSU of 250 W, while the NVIDIA part is an IGP (integrated graphics processor) with no power connectors and no suggested PSU listed. The bus interfaces differ as well: the Intel card uses PCIe 5.0 x8, while the NVIDIA part uses PCIe 5.0 x16.

Where Each One Wins

The recorded data shows no benchmark category where the Intel Arc Pro B50 wins outright. The NVIDIA GeForce RTX 5070 Mobile wins all seven head-to-head tests. However, the relative margins indicate where the Intel card is less disadvantaged. The smallest gap appears in the DirectX 12 test, where the RTX 5070 Mobile leads by only 31.2%. This suggests that the Arc Pro B50's Xe2-HPG architecture is more competitive in modern, highly parallel DirectX 12 workloads than in older APIs. The GPU Compute test shows a 27.1% gap, which is the second-smallest margin, indicating that the Intel part's higher FP16 throughput (21.30 TFLOPS) provides some compute advantage, even if it does not translate into a win.

The largest gaps are in the legacy DirectX 10 and DirectX 11 tests, where the RTX 5070 Mobile leads by 55% and 47.9% respectively. These results indicate that the Intel architecture is particularly weak in older, less parallel rendering paths. The 3D performance gap of 38.3% in the G3D test places the Arc Pro B50 firmly in a lower performance tier, and the 2D test gap of 20% shows that even basic desktop rendering favors the NVIDIA part.

For use cases, the RTX 5070 Mobile is the clear choice for any workload that depends on raw 3D rendering, legacy API compatibility, or high-bandwidth memory access. The Arc Pro B50, with its larger 16 GB frame buffer, might be considered for tasks that require large memory pools, such as certain compute or AI inference workloads, but the data shows it loses in compute performance anyway. The NVIDIA part's 8 GB of GDDR7 memory is smaller but faster, and the 384.0 GB/s bandwidth is a decisive advantage in practice.

The Verdict

The data supports a clear verdict in favor of the NVIDIA GeForce RTX 5070 Mobile. It wins every benchmark in the comparison, posts an average score that is more than ten times higher, and does so while consuming 20 W less power. The RTX 5070 Mobile's 4,608 shading units, 36 RT cores, and 144 tensor cores, combined with 384.0 GB/s of GDDR7 bandwidth, deliver a performance profile that places it in the 75th percentile of all GPUs. The Intel Arc Pro B50, with its 2,048 shading units and 224.0 GB/s of GDDR6 bandwidth, sits in the 17th percentile.

The nearest rivals in the database further contextualize the gap. The Arc Pro B50's average score of 2,660 places it near the NVIDIA GeForce GT 1030 (2,662), the NVIDIA Quadro K1100M (2,664), and the NVIDIA GeForce GT 440 (2,645), with deltas of only -0.1%, -0.2%, and 0.6% respectively. It is also within 1.1% of the NVIDIA GeForce RTX 5070 SUPER, which scores 2,690, a figure that seems anomalous in this context but is recorded in the database. The RTX 5070 Mobile's average score of 29,928 is close to the NVIDIA GeForce RTX 3070 Ti (29,945, delta -0.1%), the NVIDIA GeForce RTX 2080 Ti (29,783, delta 0.5%), the AMD Radeon RX 6800 (30,095, delta -0.6%), and the AMD Radeon RX 6700 (30,433, delta -1.7%). This places the mobile NVIDIA part in the performance class of desktop GPUs from the previous generation.

For a buyer or system integrator, the choice is unambiguous from the data. The NVIDIA GeForce RTX 5070 Mobile is the superior performer in every measured category, from legacy DirectX to modern compute. The Intel Arc Pro B50 offers a larger memory pool and a higher boost clock, but these specifications do not translate into benchmark wins. The RTX 5070 Mobile's superior architecture, higher core counts, and faster memory make it the only rational choice for performance-sensitive applications. The Intel card might be considered for niche scenarios where 16 GB of memory is a hard requirement, but the recorded performance data shows that it loses even in memory-heavy compute tests. The launch MSRP for the Intel Arc Pro B50 is 349 USD, but the RTX 5070 Mobile has no listed launch MSRP, and the performance gap is so wide that pricing does not alter the conclusion.
