The reason is still the same as what was circulating many months ago. Video card drivers are a tough nut to crack and Intel is still keeping everything tightly under wraps:
Since the actual hardware, the firmware and the final clock rates are unlikely to change, the cause has to be found in the software, i.e. the drivers. Apart from the fact that Intel very restrictively prevents any tests with an online connection through the already distributed test samples (insider tests), according to several statements even these preferred testers are not yet all clear about which driver can already give a realistic image of the expected performance. Because driver versions are still traded like pure gold internally here, too, and the contradictions are said to accumulate. Camouflage and deception or simply panicky secrecy?Igor suggests AMD and NVIDIA do not see Intel's first-generation as a major threat. The cancellation of the GeForce RTX 3070 Ti 16GB may imply that NVIDIA expects the A770 to perform on or just below a GeForce RTX 3070. The design of AMD's Radeon RX 6750XT implies something similarly.
