The Verdict

The recorded data indicates two very different design targets. The Intel Arc B770 is a desktop-oriented card with a 225 W TDP, dual-slot cooler, and discrete power connectors. The NVIDIA GeForce RTX 4080 Max-Q is a mobile part with a 60 W TDP, IGP form factor, and no power connectors. These are not direct competitors in the traditional sense; the Max-Q designation implies an efficiency-focused mobile implementation.

For raw FP32 performance, the NVIDIA part holds a marginal edge at 20.04 TFLOPS versus 19.66 TFLOPS. For FP16 workloads, the Intel card is decisively ahead at 39.32 TFLOPS versus 20.04 TFLOPS. The Intel Arc B770 also offers more memory capacity (16 GB vs 12 GB) and higher bandwidth (512.0 GB/s vs 432.0 GB/s).

The choice between these GPUs depends on the form factor and power envelope. The NVIDIA GeForce RTX 4080 Max-Q suits thin-and-light mobile systems where 60 W power draw and IGP integration are mandatory. The Intel Arc B770 targets desktop builds with adequate cooling and a 550 W power supply. Users requiring higher FP16 throughput or more memory bandwidth would favor the Intel part. Users constrained by power or physical footprint would select the NVIDIA part.

Head-to-Head Benchmarks

Direct benchmark comparisons are not available in the database for this pairing. However, the specification-level data provides measurable differences across several key metrics.

FP32 compute: The NVIDIA GeForce RTX 4080 Max-Q delivers 20.04 TFLOPS, which is approximately 1.9% higher than the Intel Arc B770's 19.66 TFLOPS. This is a narrow margin, effectively placing them in the same performance tier for single-precision workloads.

FP16 compute: The Intel Arc B770 achieves 39.32 TFLOPS with a 2:1 ratio. The NVIDIA part manages 20.04 TFLOPS with a 1:1 ratio. The Intel card is 96.2% faster in FP16 throughput, a substantial advantage for workloads that can utilize reduced precision.

Pixel fill rate: The Intel Arc B770 outputs 307.2 GPixel/s versus 108.0 GPixel/s for the NVIDIA part. The Intel card is 184.4% faster in pixel throughput, which indicates a strong advantage in rasterization-bound scenarios.

Texture fill rate: The Intel Arc B770 achieves 614.4 GTexel/s compared to 313.2 GTexel/s for the NVIDIA GeForce RTX 4080 Max-Q. This represents a 96.2% advantage for the Intel card, driven by its higher TMU count (256 vs 232) and much higher clock speeds.

Memory bandwidth: The Intel Arc B770 provides 512.0 GB/s versus 432.0 GB/s for the NVIDIA part. The Intel card is 18.5% ahead, aided by a wider 256-bit bus versus 192-bit, though the NVIDIA part uses faster effective memory (18 Gbps vs 16 Gbps).

Clock speeds: The Intel Arc B770 runs at 2100 MHz base and 2400 MHz boost. The NVIDIA GeForce RTX 4080 Max-Q runs at 795 MHz base and 1350 MHz boost. The Intel card's boost clock is 77.8% higher. This clock disparity is expected given the NVIDIA part's 60 W power target.

The NVIDIA part counters with a larger shader count: 7424 shading units versus 4096. It also has 58 RT cores versus 32, and 232 tensor cores (the Intel part lists none). These architectural resources may benefit ray tracing and AI-accelerated workloads, though without benchmark scores the database cannot quantify the real-world impact.

The remaining fields are identical or not listed for both parts: both use PCIe 4.0 x16, both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both are built on a 5 nm process at TSMC. Neither has a launch MSRP in the database.

Architecture Differences

The Intel Arc B770 uses the Xe2-HPG architecture under the Battlemage (Arc 7) generation. The NVIDIA GeForce RTX 4080 Max-Q uses Ada Lovelace under the GeForce 40 Mobile generation. Both are manufactured on a 5 nm process at TSMC, but the implementations diverge substantially.

The Intel chip, BMG-G31, has a die size of 368 mm² with transistor count listed as unknown. The NVIDIA chip, AD104, is smaller at 294 mm² but packs 35,800 million transistors, resulting in a transistor density of 121.8M / mm². The Intel part does not list a density figure, but its larger die with fewer shading units (4096 vs 7424) suggests a lower density design.

Shader architecture differs notably. The NVIDIA part uses 7424 shading units, 232 TMUs, and 80 ROPs. The Intel part uses 4096 shading units, 256 TMUs, and 128 ROPs. The Intel card has more texture units and ROPs, which explains its higher pixel and texture fill rates despite lower shader counts.

Ray tracing resources favor NVIDIA: 58 RT cores versus 32. The NVIDIA part also includes 232 tensor cores, while the Intel database entry lists none. This indicates different approaches to accelerated workloads, with NVIDIA dedicating more silicon to ray tracing and tensor operations.

Memory architecture differs in capacity and width. The Intel card uses 16 GB of GDDR6 on a 256-bit bus. The NVIDIA card uses 12 GB of GDDR6 on a 192-bit bus. The Intel part achieves higher bandwidth (512.0 GB/s vs 432.0 GB/s) despite the NVIDIA part's faster memory clock (18 Gbps effective vs 16 Gbps effective), because the wider bus compensates.

Power and thermal design are the most significant architectural differentiators. The Intel Arc B770 is a dual-slot desktop card with a 225 W TDP and a suggested 550 W power supply. The NVIDIA GeForce RTX 4080 Max-Q is an IGP with a 60 W TDP and no power connectors. This 165 W difference in TDP reflects the mobile versus desktop design philosophy.

Clock behavior reflects the power targets. The Intel card runs at 2100 MHz base and 2400 MHz boost. The NVIDIA part runs at 795 MHz base and 1350 MHz boost. The Intel card's higher clocks contribute to its fill rate advantages, while the NVIDIA part's lower clocks keep power consumption minimal.

FP16 capability differs by design: the Intel part achieves 39.32 TFLOPS with a 2:1 ratio, while the NVIDIA part achieves 20.04 TFLOPS with a 1:1 ratio. This suggests the Intel architecture provides dedicated or doubled FP16 throughput, whereas the NVIDIA part processes FP16 at the same rate as FP32.

The release timeline also separates these parts. The NVIDIA GeForce RTX 4080 Max-Q launched on January 3, 2023, and remains in Active production. The Intel Arc B770 carries a release date of January 1, 2026. The NVIDIA part's predecessor is GeForce 30 Mobile with successor GeForce 50 Mobile; the Intel part's predecessor is Alchemist with no successor listed.
