Intel Arc B770 vs NVIDIA GeForce RTX 4090 Max-Q Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the Intel Arc B770 and the NVIDIA GeForce RTX 4090 Max-Q. Both entries list empty benchmark arrays and identical percentile standings (50th percentile versus all GPUs), with zero average benchmark scores. Consequently, the comparative analysis below relies entirely on the specification differences documented in the database, interpreted through the lens of known hardware behavior.

The most significant numerical gap appears in raw compute throughput. The RTX 4090 Max-Q delivers 28.31 TFLOPS of FP32 performance, while the Arc B770 provides 19.66 TFLOPS. That difference translates to roughly 44% higher FP32 output for the NVIDIA part. In FP16 workloads, the gap narrows considerably: the RTX 4090 Max-Q operates at 28.31 TFLOPS with a 1:1 ratio, whereas the Arc B770 reaches 39.32 TFLOPS using a 2:1 shader-based path. The Intel part therefore holds a 38.9% advantage in peak FP16 throughput, assuming the 2:1 mode is supported by the workload.

Memory bandwidth favors the RTX 4090 Max-Q, which records 576.0 GB/s against the Arc B770's 512.0 GB/s. That 12.5% bandwidth advantage can matter in texture-heavy scenes and large data transfers. Both cards use 16 GB of GDDR6 memory on a 256-bit bus, so capacity and bus width are identical. The NVIDIA part runs its memory at 2250 MHz (18 Gbps effective), while the Intel part operates at 2000 MHz (16 Gbps effective).

Pixel throughput tells a different story. The Arc B770 generates 307.2 GPixel/s, nearly double the RTX 4090 Max-Q's 163.0 GPixel/s. The Intel part also leads in texture fill rate, posting 614.4 GTexel/s versus 442.3 GTexel/s, a 38.9% margin. These figures reflect a higher base clock (2100 MHz versus 930 MHz) and a higher boost clock (2400 MHz versus 1455 MHz) on the Arc B770, even though the NVIDIA chip carries many more execution units.

Shader resources strongly favor NVIDIA. The RTX 4090 Max-Q contains 9728 shading units, 304 texture mapping units, and 112 ROPs. The Arc B770 counters with 4096 shading units, 256 TMUs, and 128 ROPs. The NVIDIA part offers 2.4 times the shader count and 1.2 times the TMU count, yet the Intel part still achieves higher texture and pixel rates due to its clock advantage. Ray tracing hardware also differs: the RTX 4090 Max-Q has 76 RT cores, while the Arc B770 has 32. The NVIDIA part includes 304 tensor cores, a feature absent from the Arc B770's specification list.

Power draw presents the clearest usage distinction. The RTX 4090 Max-Q is rated at 80 W TDP and uses no external power connectors, classified as an integrated graphics processor (IGP) in the database. The Arc B770 carries a 225 W TDP, requires dual-slot cooling, and needs one 6-pin plus one 8-pin power connector, with a suggested 550 W power supply. That 145 W difference defines their deployment scenarios: one belongs in a power-constrained mobile chassis, the other in a desktop tower.

The Verdict

The data points to distinct roles rather than a single winner. The NVIDIA GeForce RTX 4090 Max-Q delivers higher absolute compute throughput (28.31 TFLOPS FP32), more than twice the shading units (9728 versus 4096), 2.4 times the ray tracing cores (76 versus 32), and 304 tensor cores for AI-accelerated workloads. It also provides broader memory bandwidth (576.0 GB/s versus 512.0 GB/s) while consuming only 80 W. For any application that scales with shader count, tensor core acceleration, or ray tracing, the recorded specifications favor the NVIDIA part decisively.

The Intel Arc B770 counters with substantially higher clock speeds (2100 MHz base and 2400 MHz boost versus 930 MHz and 1455 MHz), leading to superior pixel throughput (307.2 GPixel/s versus 163.0 GPixel/s) and texture throughput (614.4 GTexel/s versus 442.3 GTexel/s). Its FP16 output reaches 39.32 TFLOPS, exceeding the RTX 4090 Max-Q's 28.31 TFLOPS. However, the Intel card demands 225 W and a dedicated power supply, making it unsuitable for the same low-power mobile environments where the NVIDIA part operates.

Users constrained by power budgets or chassis size should choose the RTX 4090 Max-Q, as its 80 W envelope and connector-free design enable placement in compact or integrated systems. Users prioritizing raw fill rates and FP16 throughput, and who can accommodate a 225 W dual-slot card, should select the Arc B770. The RTX 4090 Max-Q also has a release date of 2023-01-02, whereas the Arc B770 lists 2025-12-31, indicating a newer market entry for the Intel product.

Die characteristics show modest differences. The Arc B770 measures 368 mm² on a 5 nm TSMC process, while the RTX 4090 Max-Q measures 379 mm² on the same 5 nm TSMC node. The NVIDIA chip contains 45,900 million transistors with a density of 121.1M per mm²; the Intel chip's transistor count is listed as unknown.

Architecture Differences

The Intel Arc B770 uses the BMG-G31 chip based on Xe2-HPG architecture, belonging to the Battlemage (Arc 7) generation. Its predecessor is listed as Alchemist. The NVIDIA GeForce RTX 4090 Max-Q uses the AD103 chip based on Ada Lovelace architecture, part of the GeForce 40 Mobile generation. Its predecessor is GeForce 30 Mobile and its successor is GeForce 50 Mobile.

Both processors are fabricated on a 5 nm process at TSMC, but their architectural priorities diverge. The Xe2-HPG design emphasizes high clock rates and raw fill throughput, as evidenced by the Arc B770's 2100 MHz base clock and its leading pixel and texture rates. The Ada Lovelace design concentrates on parallel compute breadth, using 9728 shading units and 304 tensor cores to achieve higher FP32 throughput despite much lower clocks.

Ray tracing implementation differs in scale. The RTX 4090 Max-Q allocates 76 dedicated RT cores, more than double the Arc B770's 32 RT cores. Tensor core support exists only on the NVIDIA part, with 304 units dedicated to AI and deep learning operations. The Intel card lists no tensor core count, indicating a different approach to accelerated compute.

The memory subsystem shares the same 256-bit GDDR6 configuration, but the NVIDIA part runs at a higher effective speed (18 Gbps versus 16 Gbps), producing its 576.0 GB/s bandwidth. FP16 processing differs fundamentally: the Arc B770 achieves 39.32 TFLOPS through a 2:1 shader-based path, while the RTX 4090 Max-Q sustains 28.31 TFLOPS at a full 1:1 ratio, suggesting different precision handling strategies.

Production status distinguishes the pair. The RTX 4090 Max-Q is marked as Active, while the Arc B770's production status is not recorded. Release timing also separates them, with the NVIDIA part appearing in early 2023 and the Intel part slated for late 2025.

Where Each One Wins

The NVIDIA GeForce RTX 4090 Max-Q wins in scenarios demanding maximum shader throughput, ray tracing performance, and AI acceleration. Its 9728 shading units, 76 RT cores, and 304 tensor cores provide the hardware foundation for compute-heavy workloads such as path-traced rendering, machine learning inference, and FP32 simulation tasks. The 28.31 TFLOPS FP32 output and 576.0 GB/s memory bandwidth support these operations effectively. The 80 W power envelope makes it viable for thin-and-light laptops, compact systems, and any environment where thermal and electrical budgets are tight. The absence of power connectors simplifies installation in integrated or proprietary chassis.

The Intel Arc B770 wins in scenarios prioritizing fill rate, FP16 throughput, and clock-driven performance. Its 307.2 GPixel/s pixel rate and 614.4 GTexel/s texture rate exceed the NVIDIA part by wide margins, benefiting applications that saturate ROPs and TMUs, such as high-resolution rasterization and texture-heavy game scenes. The 39.32 TFLOPS FP16 output gives it an edge in half-precision workloads when the 2:1 mode is applicable. The higher base and boost clocks (2100 MHz and 2400 MHz) suggest responsiveness in latency-sensitive tasks. The 256-bit bus and 512.0 GB/s bandwidth remain substantial for a 16 GB frame buffer, and the dual-slot design with explicit power connectors suits desktop builds where power delivery is not a constraint.

Both cards share identical memory capacity (16 GB) and bus width (256 bit), so capacity-limited workloads will behave similarly. The RTX 4090 Max-Q's higher bandwidth and transistor count (45,900 million versus unknown) indicate an advantage in data-intensive parallel workloads. The Arc B770's lower shading unit count (4096 versus 9728) but higher clocks suggest it may excel in latency-bound operations that do not scale linearly with core count. Users needing portability, tensor acceleration, or maximum ray tracing should rely on the NVIDIA part. Users needing maximum pixel throughput, FP16 throughput, or clock speed should rely on the Intel part.
