The Passmark G3D score of 7615 suggests it handles modern 3D workloads reasonably, while the G2D score of 969 indicates adequate 2D performance.

The Intel Arc Pro B65 wins in raw specification comparisons. It has 2560 shading units versus 768, 160 TMUs versus 48, and 80 ROPs versus 16. It has 20 ray tracing cores versus 12. Its FP32 throughput of 12.29 TFLOPS is nearly three times the AMD part's 4.454 TFLOPS. Its FP16 performance of 24.58 TFLOPS is over five times the AMD part's 4.454 TFLOPS. The memory subsystem is vastly different, with 32 GB of dedicated GDDR6 at 608.0 GB/s versus system shared memory. The pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s far exceed the AMD part's 46.40 GPixel/s and 139.2 GTexel/s. The Intel part also has a higher base clock of 2400 MHz, which is fixed, versus the AMD part's 400 MHz base clock. The Intel part supports PCIe 5.0 x16 versus PCIe 4.0 x8 and offers four DisplayPort 2.1 outputs versus portable device dependent outputs.

The use cases follow from the data. The AMD Radeon 880M is the only option with recorded performance. It suits systems requiring low power consumption, as its 15 W TDP and no power connectors indicate. The Intel Arc Pro B65, with its 200 W TDP, 8-pin connector, and 550 W suggested PSU, targets discrete installation in a desktop or larger mobile chassis. The Intel part's specification sheet suggests higher compute throughput, but without benchmark scores, the database cannot confirm real-world performance. The AMD part's nearest rival data shows it competes with older discrete mobile GPUs, placing it in a specific performance tier. The Intel part's 50th percentile rank, despite no scores, indicates it is recognized in the database but unverified. Buyers seeking verified performance should consider the AMD Radeon 880M. Buyers requiring the specification advantages of the Intel part must rely on its listed specs alone, as no measured data exists to validate its performance.
