The average benchmark score for the RTX PRO 5000 is 6,407. This figure aggregates all eight tests. The Arc B770’s average is zero due to missing data. The wins tally shows zero for both cards in head-to-head testing, since no direct comparisons were recorded. The data indicates that the RTX PRO 5000’s benchmark profile is mixed, with strong scores in specific tests like PassMark G3D and 3DMark Steel Nomad, but weaker scores in legacy DirectX tests.

The Verdict

The data points to the RTX PRO 5000 72 GB Blackwell as the choice for compute-heavy workloads requiring massive memory capacity. Its 72 GB GDDR7 memory, 1.34 TB/s bandwidth, and 440 tensor cores make it suited for large datasets, AI inference, and rendering tasks that exceed the Arc B770’s 16 GB limit. The 66.94 TFLOPS FP32 performance is more than triple the Intel card’s 19.66 TFLOPS, and the 110 RT cores provide robust ray tracing capability. The PCIe 5.0 interface and 300 W TDP align with professional workstation usage.

The Intel Arc B770 appeals to users prioritizing lower power consumption and a more modest footprint. Its 225 W TDP and 550 W PSU requirement are easier to accommodate in standard desktop builds. The higher base clock of 2100 MHz and boost clock of 2400 MHz indicate good frequency behavior for its architecture. The inclusion of an HDMI 2.1a output provides flexibility for consumer displays. The 50th percentile ranking suggests it performs near the median of all GPUs, making it a balanced option for general gaming and entry-level professional work.

The RTX PRO 5000’s 37th percentile ranking appears inconsistent with its raw specifications. The benchmark scores show high performance in modern tests but lower scores in legacy APIs, which may skew the aggregate. The nearest rivals being older cards like the GTX 460 SE suggests the recorded benchmarks may not represent the card’s true position. The Arc B770 lacks recorded benchmarks entirely, so its ranking comes from unspecified sources. The choice depends on whether the user needs the NVIDIA card’s extreme memory and compute resources or the Intel card’s efficiency and lower system requirements.
