The Verdict

The data indicates that the NVIDIA RTX PRO 4000 Blackwell is the dominant performer across every measured category. It wins on compute throughput, memory capacity, memory bandwidth, and benchmark scores. Its 24 GB of GDDR7 memory and 672.0 GB/s bandwidth suit large datasets, while its 36.83 TFLOPS FP32 and FP16 performance handles heavy compute workloads. The 280 tensor cores add dedicated acceleration for AI tasks, and the 70 ray tracing cores provide hardware support for ray-traced rendering. The nearest rival data confirms its position: it trails the RTX 3090 by only 1.6 percent and the RX 6700 XT by 1.1 percent, while leading the RTX A4000 by 1.7 percent.

The Intel Arc G3 Extreme is an integrated processor for portable devices, and the database shows no benchmark results for it. Its 80 W power draw and lack of external power connectors make it suitable for compact systems, but its 1536 shading units and 7.680 TFLOPS FP32 performance place it far behind the discrete NVIDIA card. The system shared memory design means bandwidth is system dependent, which limits its performance in memory-intensive tasks. The Intel part does have a higher boost clock at 2500 MHz versus 2055 MHz, but the NVIDIA card compensates with 5.8 times the shading units and 5.8 times the texture mapping units.

The release dates show the Intel part launches on 2026-05-31, over a year after the NVIDIA card on 2025-03-17. Both cards support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The NVIDIA card uses a TSMC 5 nm process with a 120.6M per mm² transistor density, while the Intel card uses a 3 nm process with unknown transistor details. The choice depends on the use case. A portable device with tight power limits would use the Intel IGP. A workstation or desktop requiring maximum compute and memory performance would use the NVIDIA RTX PRO 4000 Blackwell. The recorded data leaves no ambiguity about which GPU delivers higher raw performance.
