The Verdict

The recorded data indicates that the Intel Arc B770 and NVIDIA RTX 3000 Mobile Ada Generation target fundamentally different segments. The Arc B770 is a desktop dual-slot card with a 225 W TDP, 16 GB of memory, and 512.0 GB/s bandwidth. The RTX 3000 Mobile Ada Generation is a mobile IGP with a 115 W TDP, 8 GB of memory, and 256.0 GB/s bandwidth.

The Arc B770 wins decisively in memory capacity, memory bandwidth, pixel throughput, texture throughput, and FP32 compute. It also has higher clock speeds and a larger die size at 368 mm² versus 188 mm². The RTX 3000 Mobile Ada Generation counters with more shading units (4608 versus 4096), more RT cores (36 versus 32), and 144 tensor cores, which the Arc B770 does not list. It also has a much lower power envelope at 115 W versus 225 W.

For users building a desktop system with room for a dual-slot card and a 550 W PSU, the Arc B770 data shows clear advantages in memory and rasterization throughput. For mobile or low-power applications where the IGP form factor and 115 W TDP matter, the RTX 3000 Mobile Ada Generation is the only viable choice between the two. The RTX 3000 also benefits from having started production earlier, with an Active status, while the Arc B770 has no production status recorded.

The data does not support a single overall winner. The choice depends on form factor and power constraints. Desktop users with power headroom should favor the Arc B770. Users needing a mobile GPU with tensor core support should favor the RTX 3000 Mobile Ada Generation.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the Intel Arc B770 and NVIDIA RTX 3000 Mobile Ada Generation. Both GPUs hold a 50th percentile position against all GPUs in the database, and both have an average benchmark score of 0. With no recorded benchmark wins for either side, the comparison relies entirely on the specification-level data.

The largest specification advantage for the Intel Arc B770 is in memory bandwidth. The Arc B770 delivers 512.0 GB/s, exactly double the 256.0 GB/s of the RTX 3000 Mobile Ada Generation. This is accompanied by double the memory capacity (16 GB versus 8 GB) and double the bus width (256 bit versus 128 bit). Memory-heavy workloads would favor the Arc B770 substantially.

Pixel fill rate favors the Arc B770 by a wide margin. The Arc B770 achieves 307.2 GPixel/s, which is approximately 3.8 times the 81.36 GPixel/s of the RTX 3000 Mobile Ada Generation. Texture fill rate shows a similar pattern, with the Arc B770 at 614.4 GTexel/s versus 244.1 GTexel/s for the RTX 3000, a lead of roughly 2.5 times.

Compute throughput also favors the Arc B770. In FP32, the Arc B770 delivers 19.66 TFLOPS versus 15.62 TFLOPS for the RTX 3000, a lead of about 26%. In FP16, the Arc B770 delivers 39.32 TFLOPS versus 15.62 TFLOPS, a lead of roughly 152%. However, the RTX 3000 has a 1:1 FP16 ratio while the Arc B770 uses a 2:1 ratio, meaning the Arc B770's FP16 advantage may be achieved through rate-limited execution.

The RTX 3000 Mobile Ada Generation counters with a higher shading unit count (4608 versus 4096), more RT cores (36 versus 32), and 144 tensor cores where the Arc B770 lists none. The RTX 3000 also has lower clock speeds (1695 MHz boost versus 2400 MHz boost) but compensates with a lower TDP of 115 W versus 225 W.
