Intel Arc B770 vs NVIDIA RTX 5000 Mobile Ada Generation Comparison

The Verdict

The Intel Arc B770 and NVIDIA RTX 5000 Mobile Ada Generation target different segments entirely. The Arc B770 is a desktop-oriented, dual-slot 225 W card built on the Battlemage architecture, while the RTX 5000 Mobile Ada is a 120 W mobile-class IGP based on Ada Lovelace. The recorded data shows the NVIDIA part with a single 3DMark Steel Nomad DX12 score of 3596, placing it at the 21st percentile of all GPUs. Its nearest rivals are all older, lower-tier cards: the GeForce GT 545 (3594, 0.1% behind), the GeForce GT 735M (3616, 0.6% ahead), the GeForce GTX 1050 (3629, 0.9% ahead), and the AMD Radeon HD 6770 (3649, 1.5% ahead). In that benchmark, the RTX 5000 Mobile Ada is effectively at parity with a decade-old GT 545, within 0.1%. The Intel Arc B770 has no benchmark scores recorded, no nearest rivals, and a 50th percentile ranking by default. Therefore, the data does not support a direct performance ranking between the two. The Arc B770 is the choice for a desktop user seeking high raw throughput figures, while the RTX 5000 Mobile Ada is the choice for a mobile workstation requiring integrated graphics with a modest 120 W envelope.

Architecture Differences

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two GPUs. The only recorded benchmark belongs to the RTX 5000 Mobile Ada: 3DMark Steel Nomad DX12 with a score of 3596. Its nearest rivals show how tightly clustered that result is. The GeForce GT 545 scores 3594, a delta of 0.1% behind. The GeForce GT 735M scores 3616, 0.6% ahead. The GeForce GTX 1050 scores 3629, 0.9% ahead. The AMD Radeon HD 6770 scores 3649, 1.5% ahead. In absolute terms, the RTX 5000 Mobile Ada is 2 points ahead of the GT 545 and 53 points behind the HD 6770. This narrow spread indicates that the mobile Ada part performs at the level of entry-level desktop GPUs from years ago in this specific DirectX 12 test. The Intel Arc B770 has no scores at all in the database, so no direct comparison can be made. Its 50th percentile ranking is a placeholder, not a measured outcome. Consequently, the data cannot confirm which GPU is faster in any workload.

Where Each One Wins

The RTX 5000 Mobile Ada wins in compute throughput. Its 41.15 TFLOPS FP32 is 109% higher than the Arc B770's 19.66 TFLOPS. It also has more shading units (9728 versus 4096), more TMUs (304 versus 256), more RT cores (76 versus 32), and 304 tensor cores where the Intel part has none recorded. Memory bandwidth favors NVIDIA at 576.0 GB/s versus 512.0 GB/s. Texture rate is slightly higher on NVIDIA at 643.0 GTexel/s versus 614.4 GTexel/s. Power efficiency also favors the mobile part: 120 W versus 225 W TDP, with no power connectors required and an IGP form factor. The Arc B770 wins in pixel throughput, delivering 307.2 GPixel/s versus 236.9 GPixel/s for the RTX 5000 Mobile Ada. It also has a higher boost clock (2400 MHz versus 2115 MHz) and a much higher base clock (2100 MHz versus 1425 MHz). The Intel card supports fixed desktop display outputs (1x HDMI 2.1a, 3x DisplayPort 2.1) versus the NVIDIA part's portable device dependent outputs. The Arc B770 has more ROPs (128 versus 112). In FP16, the Intel part reaches 39.32 TFLOPS using a 2:1 ratio, while the NVIDIA part achieves 41.15 TFLOPS at 1:1, so NVIDIA retains the lead there. The Arc B770 is the only one of the two with a recorded 550 W suggested PSU, reflecting its desktop power design. The RTX 5000 Mobile Ada is the only one with an active production status and the only one with a measured benchmark result. For a user prioritizing raw compute, tensor capability, memory bandwidth, and low power draw, the RTX 5000 Mobile Ada is the data-backed pick. For a user prioritizing pixel fill rate, high clocks, and fixed desktop connectivity, the Arc B770 has the recorded specification advantage.
