Architecture Differences

The Intel Arc B770 and NVIDIA GeForce RTX 5090 Mobile represent two fundamentally different design philosophies. The Arc B770 comes from Intel's Battlemage generation, built on the Xe2-HPG architecture with the BMG-G31 chip. The RTX 5090 Mobile uses NVIDIA's Blackwell 2.0 architecture with the GB203 chip. Both chips are fabricated on a 5 nm process at TSMC, yet their internal layouts diverge sharply.

The NVIDIA chip packs 45,600 million transistors into a 378 mm² die, yielding a transistor density of 120.6M per mm². The Intel chip has an unknown transistor count but occupies a 368 mm² die. This close die size with vastly different transistor counts indicates the NVIDIA design packs considerably more logic into similar silicon area.

Compute resources tell the story of divergent priorities. The RTX 5090 Mobile fields 10,496 shading units, 328 TMUs, and 82 RT cores. The Arc B770 counters with 4,096 shading units, 256 TMUs, and 32 RT cores. The Intel GPU takes the lead in ROPs with 128 versus 112 on the NVIDIA part. The NVIDIA GPU also integrates 328 tensor cores, while the Intel card lists no tensor core count.

Memory architecture separates these GPUs further. The RTX 5090 Mobile uses GDDR7 memory with 28 Gbps effective speed, reaching 896.0 GB/s bandwidth across its 256-bit bus. The Arc B770 uses GDDR6 at 16 Gbps effective, achieving 512.0 GB/s over the same 256-bit bus width. The NVIDIA card's memory runs at a lower base clock of 1750 MHz but achieves higher effective throughput, while the Intel memory runs at 2000 MHz base.

The power envelopes could not be more different. The Arc B770 draws 225 W with a dual-slot cooler and external power connectors. The RTX 5090 Mobile operates at 95 W as an integrated graphics package with no power connectors. This reflects their intended deployment: the Intel card targets desktop systems with dedicated power delivery, while the NVIDIA part is designed for mobile integration.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Arc B770 uses PCIe 4.0 x16, while the RTX 5090 Mobile uses PCIe 5.0 x16. Display outputs differ as well: the Intel card provides one HDMI 2.1a and three DisplayPort 2.1 connections, while the NVIDIA card's outputs are described as portable device dependent.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the Intel Arc B770 and NVIDIA GeForce RTX 5090 Mobile. The Arc B770 has zero recorded benchmark scores and zero wins, while the RTX 5090 Mobile has ten recorded benchmark entries and zero direct wins against the Intel card.

The RTX 5090 Mobile's benchmark results span multiple test suites. In 3DMark Steel Nomad DX12, it scores 5,871. Geekbench OpenCL returns 201,834, and Geekbench Vulkan returns 198,405. PassMark tests show a G3D score of 30,034, a GPU compute score of 13,401, and a G2D score of 1,057. Legacy DirectX tests in PassMark yield scores of 324 for DX9, 269 for DX11, 183 for DX10, and 138 for DX12.

These scores place the RTX 5090 Mobile at the 84th percentile among all GPUs. Its average benchmark score of 45,152 positions it near several close rivals. The AMD Radeon Pro 5500 XT scores 45,384, which is 0.5% higher. The NVIDIA GeForce RTX 4070 Ti scores 44,795, which is 0.8% lower. The Intel Arc A730M scores 45,592, 1% higher. The NVIDIA RTX 5880 Ada Generation scores 45,972, 1.8% higher.

The data suggests the RTX 5090 Mobile performs in a tight cluster with these four rivals, all within roughly 2% of each other. This narrow spread indicates the mobile NVIDIA part delivers desktop-class performance in its segment. The Arc B770's lack of benchmark data prevents any direct performance comparison, leaving its position relative to the RTX 5090 Mobile undefined in the database.

The absence of head-to-head results and the Arc B770's zero benchmark scores mean the database records no wins for either GPU in direct competition. The RTX 5090 Mobile's individual test scores provide the only quantitative performance information available.

The clock speeds reveal an interesting inversion. The Arc B770 runs at 2100 MHz base and 2400 MHz boost, far higher than the RTX 5090 Mobile's 990 MHz base and 1515 MHz boost. Despite lower clocks, the NVIDIA card achieves higher FP32 throughput due to its larger shader array. The Intel card compensates with higher pixel rate (307.2 GPixel/s versus 169.7 GPixel/s) and texture rate (614.4 GTexel/s versus 496.9 GTexel/s).

The Verdict

The database presents a clear asymmetry. The RTX 5090 Mobile has extensive benchmark coverage, an 84th percentile standing, and an average score of 45,152. The Arc B770 has no benchmark scores, a 50th percentile rating, and no recorded performance data. Any comparison based on recorded measurements must favor the NVIDIA card simply because it has measurable results.

The RTX 5090 Mobile's nearest rivals cluster tightly around its average score. The AMD Radeon Pro 5500 XT sits 0.5% higher, the Intel Arc A730M sits 1% higher, and the NVIDIA RTX 5880 Ada Generation sits 1.8% higher. Only the GeForce RTX 4070 Ti sits lower at 0.8% below. This grouping indicates the RTX 5090 Mobile belongs in a specific performance tier, and the database places it there with confidence.

The Arc B770's specifications suggest a different design target. Its higher clocks, dual-slot cooler, and 225 W TDP point to desktop deployment. Its 16 GB memory and 512.0 GB/s bandwidth are substantial but below the NVIDIA card's 24 GB and 896.0 GB/s. The Intel card's FP16 throughput of 39.32 TFLOPS exceeds the NVIDIA card's 31.80 TFLOPS, but this advantage applies only to workloads using the 2:1 ratio.

The verdict from the data is straightforward: the RTX 5090 Mobile is the only GPU in this comparison with validated benchmark results, and those results place it in the 84th percentile. The Arc B770's performance remains unquantified in the database. Users seeking a GPU with measured performance data should consider the NVIDIA card. Users interested in the Intel architecture must rely solely on its listed specifications.

Where Each One Wins

The RTX 5090 Mobile wins in every category the database can measure. It has benchmark scores, the Arc B770 has none. It holds an 84th percentile ranking versus 50th for the Intel card. Its average score of 45,152 stands against no recorded average for the Arc B770.

In memory capacity, the NVIDIA card leads with 24 GB versus 16 GB. Memory bandwidth also favors NVIDIA at 896.0 GB/s versus 512.0 GB/s. Shading units, TMUs, RT cores, and tensor cores all favor the NVIDIA card. FP32 compute favors NVIDIA at 31.80 TFLOPS versus 19.66 TFLOPS.

The Arc B770 wins in several specification categories. Its base clock of 2100 MHz and boost clock of 2400 MHz far exceed the NVIDIA card's 990 MHz and 1515 MHz. Pixel rate favors Intel at 307.2 GPixel/s versus 169.7 GPixel/s. Texture rate favors Intel at 614.4 GTexel/s versus 496.9 GTexel/s. FP16 throughput favors Intel at 39.32 TFLOPS versus 31.80 TFLOPS. The Intel card also has more ROPs at 128 versus 112.

Power characteristics split the two. The Arc B770 draws 225 W, while the RTX 5090 Mobile draws 95 W. The NVIDIA card's lower power requirement suits mobile integration, while the Intel card's higher power budget supports desktop performance. The RTX 5090 Mobile's release date of 2025-03-26 precedes the Arc B770's 2025-12-31, making the Intel card a later release.

The use-case split follows these patterns. The RTX 5090 Mobile serves applications needing high memory bandwidth, large memory pools, and low power consumption in a portable form factor. The Arc B770 serves applications where raw clock speeds, pixel throughput, and FP16 compute matter more, with the flexibility of desktop power delivery. The database records no direct performance comparison, so these distinctions come entirely from the specification differences and the NVIDIA card's benchmark results.
