Intel Arc B770 vs NVIDIA RTX PRO 6000 Blackwell Server Comparison

The Verdict

The data shows two radically different server-class GPUs. The Intel Arc B770 and the NVIDIA RTX PRO 6000 Blackwell Server are not direct competitors in any measurable sense. The recorded specifications place the NVIDIA part in an entirely higher performance tier, with the Arc B770 occupying a mid-range position.

The Arc B770 is the choice for systems requiring a modern, dual-slot graphics accelerator with a 225 W power envelope, a single 6-pin plus 8-pin power configuration, and a 550 W suggested power supply. Its 16 GB of GDDR6 memory on a 256-bit bus delivers 512.0 GB/s of bandwidth, which suits workloads that do not demand massive memory capacities. The percentile data places it at the 50th percentile among all GPUs in the database, indicating a median performance position.

The RTX PRO 6000 Blackwell Server is for environments that need extreme compute throughput and memory capacity. It packs 96 GB of GDDR7 memory on a 512-bit bus, reaching 1.79 TB/s of bandwidth. Its FP32 throughput of 126.0 TFLOPS is more than six times that of the Arc B770's 19.66 TFLOPS. The NVIDIA card also requires a 600 W TDP, a single 16-pin connector, and a 1000 W suggested power supply, making it a board designed for high-end workstations or server racks with robust power delivery.

The benchmark data in the database is limited. The RTX PRO 6000 has a recorded 3DMark Steel Nomad DX12 score of 5996, which places it at the 34th percentile. Its nearest rivals in the database, based on average score, are the NVIDIA GeForce GTX 770M at 6000 (a delta of -0.1%), the AMD Radeon RX 6400 at 6001 (delta -0.1%), the AMD FirePro W4100 at 5987 (delta 0.2%), and the NVIDIA Quadro K4000M at 5986 (delta 0.2%). These deltas are negligible, meaning the database records the RTX PRO 6000 as performing within 0.2% of those older or lower-tier cards in that specific test. The Arc B770 has no recorded benchmarks in the database.

For a buyer, the decision is purely about workload requirements. If the task involves large datasets, high-resolution rendering, or AI inference requiring substantial memory and FP32 compute, the RTX PRO 6000 is the only option with the necessary specifications. If the task fits within 16 GB of memory and a 512.0 GB/s bandwidth ceiling, and power efficiency is a priority, the Arc B770 delivers a modern architecture at a fraction of the power draw.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two cards. The wins tally is zero for both. The only benchmark recorded is the RTX PRO 6000's 3DMark Steel Nomad DX12 score of 5996.

The recorded performance percentile for the RTX PRO 6000 is 34, meaning it sits below the median of all GPUs in the database despite its high specification sheet. The nearest rival comparisons show that its 5996 score is effectively tied with the NVIDIA GeForce GTX 770M (6000, delta -0.1%) and the AMD Radeon RX 6400 (6001, delta -0.1%). It also sits within 0.2% of the AMD FirePro W4100 (5987) and the NVIDIA Quadro K4000M (5986).

The Arc B770 has no benchmark scores, no percentile ranking beyond the 50th percentile placeholder, and no average score recorded. Its performance cannot be quantified from the database. The benchmark section therefore offers no direct comparison between the two cards. The specification differences, however, indicate a clear hierarchy: the RTX PRO 6000 has 6.4 times the FP32 throughput, 6 times the memory capacity, and 3.5 times the memory bandwidth of the Arc B770, while consuming 2.7 times the power.
