Intel Arc Pro B70 vs NVIDIA GeForce RTX 5090 Mobile Comparison

Head-to-Head Benchmarks

The recorded data does not include any direct head-to-head benchmark comparisons between the Intel Arc Pro B70 and the NVIDIA GeForce RTX 5090 Mobile. The database shows zero wins for each part in paired testing, and no individual scores are listed for the Intel Arc Pro B70. The RTX 5090 Mobile, however, carries a full set of measured results, and those numbers can be interpreted against its nearest rivals.

The RTX 5090 Mobile posts an average benchmark score of 45152, which places it at the 84th percentile among all GPUs in the database. Its closest measured competitor is the AMD Radeon Pro 5500 XT with an average score of 45384, a delta of -0.5%, meaning the NVIDIA part trails that AMD card by half a percentage point. Against the NVIDIA GeForce RTX 4070 Ti, the RTX 5090 Mobile leads by 0.8% (44795 average score). The Intel Arc A730M sits 1% ahead at 45592, and the NVIDIA RTX 5880 Ada Generation leads by 1.8% at 45972. The data shows the RTX 5090 Mobile is essentially peer-grouped with these four cards, with a spread of only 2.3 percentage points between its closest trailing rival and its closest leading rival.

In synthetic tests, the RTX 5090 Mobile delivers a 3DMark Steel Nomad DX12 score of 5871. Its Geekbench OpenCL result is 201834, and its Geekbench Vulkan result is 198405, a gap of 1.7% in favor of OpenCL. The PassMark suite shows a G3D score of 30034, a GPU compute score of 13401, and legacy DirectX results of 324 (DX9), 269 (DX11), 183 (DX10), and 138 (DX12). The G2D score is 1057. The compute score is less than half the G3D score, which indicates the card's geometry and fill-rate workloads scale differently from its general compute throughput.

Because the Intel Arc Pro B70 has no recorded benchmark scores, no direct wins can be claimed for either product. The only quantitative comparison available is the RTX 5090 Mobile's position relative to its listed rivals, none of which include the Intel part.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The Intel Arc Pro B70 is built on the Xe2-HPG architecture, specifically the Battlemage (Pro Series) generation, using the BMG-G31 chip. The NVIDIA GeForce RTX 5090 Mobile uses the Blackwell 2.0 architecture, part of the GeForce 50 Mobile generation, built around the GB203 chip. Both are fabricated on a 5 nm process at TSMC, but the underlying designs diverge sharply.

The RTX 5090 Mobile integrates 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6 million per mm². The Intel Arc Pro B70 has an unknown transistor count but a die size of 368 mm², which is 10 mm² smaller than the NVIDIA chip. The Intel part is a dual-slot discrete card measuring 267 mm in length, 110 mm in height, and 39 mm in width, while the RTX 5090 Mobile is an IGP package with no listed dimensions, designed for portable devices.

The NVIDIA chip carries 82 RT cores and 328 tensor cores, while the Intel part has 32 RT cores and no tensor cores listed. The RTX 5090 Mobile also has 10496 shading units, 328 TMUs, and 112 ROPs. The Intel Arc Pro B70 has 4096 shading units, 256 TMUs, and 128 ROPs. The shading unit count favors NVIDIA by a factor of 2.56, and the RT core count favors NVIDIA by 2.56 as well. The Intel part has more ROPs, 128 versus 112, which contributes to its higher pixel rate.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both use a PCIe 5.0 x16 bus interface. The display outputs differ: the Intel card offers 1x HDMI 2.1a and 3x DisplayPort 2.1, while the NVIDIA card's outputs are listed as portable device dependent. The Intel part is a standard desktop expansion card, whereas the NVIDIA part is designed for mobile integration.

The FP32 compute throughput tells a clear story. The RTX 5090 Mobile delivers 31.80 TFLOPS, while the Intel Arc Pro B70 delivers 22.94 TFLOPS, a 38.6% advantage for NVIDIA. In FP16, the Intel card reaches 45.88 TFLOPS using a 2:1 ratio, while the NVIDIA card matches its FP32 rate at 31.80 TFLOPS with a 1:1 ratio. The Intel part's FP16 output exceeds its FP32 output by exactly 2:1, indicating a different ALU design.

The Intel Arc Pro B70 has a higher base and boost clock, more ROPs, more memory capacity, and a higher pixel rate. The NVIDIA card has more shading units, TMUs, RT cores, tensor cores, higher memory bandwidth, higher FP32 throughput, and a much lower TDP.

The Verdict

The data supports a clear split. The NVIDIA GeForce RTX 5090 Mobile is the stronger compute and rendering part based on measured results: its average score of 45152, 84th percentile ranking, and 31.80 TFLOPS FP32 throughput place it in a competitive tier with desktop-class GPUs like the RTX 5880 Ada Generation, which sits only 1.8% higher. The Intel Arc Pro B70 has no recorded benchmarks, so its performance cannot be quantified from the database, but its specifications indicate a different role.

The RTX 5090 Mobile carries 82 RT cores and 328 tensor cores, making it the only one of the two with dedicated AI acceleration hardware. Its 896.0 GB/s memory bandwidth from GDDR7 exceeds the Intel card's 608.0 GB/s from GDDR6 by 47.4%. Its FP32 rate of 31.80 TFLOPS is 38.6% higher than the Intel part's 22.94 TFLOPS. The NVIDIA card also draws 135 W less power, at 95 W versus 230 W, and requires no external power connector, a decisive advantage for mobile platforms.

The Intel Arc Pro B70 counters with 32 GB of GDDR6 memory, 64 GB more capacity than the NVIDIA card's 24 GB, and a higher pixel rate of 358.4 GPixel/s versus 169.7 GPixel/s, a 2.11x advantage. Its texture rate of 716.8 GTexel/s also exceeds the NVIDIA card's 496.9 GTexel/s by 44.2%. These figures suggest the Intel part is designed for rasterization-heavy workloads with large memory footprints, not for ray tracing or AI inference.

The RTX 5090 Mobile's release date of 2025-03-26 predates the Intel part's 2026-03-25 by roughly one year. The Intel card has a launch MSRP of 949 USD, while the NVIDIA mobile part has no listed MSRP. The production status for the Intel card is not listed, while the NVIDIA card is marked active.

Where Each One Wins

The NVIDIA GeForce RTX 5090 Mobile wins on compute throughput, memory bandwidth, and feature set. Its FP32 performance of 31.80 TFLOPS and FP16 performance at the same rate make it suitable for general compute and AI workloads, reinforced by 328 tensor cores. Its 82 RT cores provide hardware ray tracing capability that the Intel part lacks in comparable density. The 896.0 GB/s memory bandwidth and GDDR7 memory type give it a significant data movement advantage. The 95 W TDP and IGP form factor make it the only viable option for portable devices, as it requires no power connectors and occupies no expansion slot.

The Intel Arc Pro B70 wins on memory capacity, pixel throughput, and texture throughput. Its 32 GB GDDR6 frame buffer is 33% larger than the NVIDIA card's 24 GB, which matters for large datasets or high-resolution textures. Its pixel rate of 358.4 GPixel/s is more than double the RTX 5090 Mobile's 169.7 GPixel/s, indicating stronger fill-rate performance for traditional rasterization. Its texture rate of 716.8 GTexel/s exceeds the NVIDIA card by 44.2%. The Intel card also operates at higher clocks, with a base of 2280 MHz and boost of 2800 MHz, versus 990 MHz and 1515 MHz for the NVIDIA part. The dual-slot design with 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs makes it a desktop workstation card, while the NVIDIA part is tied to portable device integration.

The RTX 5090 Mobile also wins on measured performance percentile, sitting at 84% versus the Intel card's 50%, though the Intel card's percentile is based on no recorded scores. The NVIDIA part's nearest rivals, including the RTX 5880 Ada Generation and RTX 4070 Ti, show it competes in the upper tier of the database. The Intel Arc Pro B70 has no rival data to contextualize its position.

For ray tracing, AI inference, and mobile deployment, the RTX 5090 Mobile is the clear choice from the recorded data. For memory-heavy rasterization tasks that need maximum frame buffer capacity and fill rate, the Intel Arc Pro B70 presents a plausible alternative, though its performance remains unmeasured in the database.
