Nvidia Ada mid-range and entry-level GPUs may only feature 8x PCIe lanes

We've already shared plenty of reports regarding the higher-end Nvidia Ada GPUs, but this time we've got details on Nvidia's mid-range and entry-level GPUs.  These are the AD106 and AD107, which are expected to power future RTX 4060 and RTX 4050 graphics cards. 

According to kopite7kimi, the AD106, which is expected to power the RTX 4060, “is not very strong”. With a typical Time Spy Extreme score below 7,000 points, this GPU matches performance with the RTX 3070. If you compare it with the RTX 3060, the score is about 45% higher.

AD106 is not very strong. The typical TSE score is < 7000.
And both AD106 and AD107 are using PCIE x8.

Moreover, the leaker also stated that the AD106 and AD107 (RTX 4050?) would only have eight PCIe lanes but didn't specify if these are PCIe Gen 4 or Gen 5. Considering Hopper already features PCIe 5.0, we assume Nvidia will use the latest version of the connectivity standard in its GPUs. However, using PCIe 4.0 would probably result in a price reduction in its production, so we'll have to wait and see.

The first graphics card using these GPUs should release in 2023 and are unlikely to be announced alongside the RTX 4090 during Nvidia's upcoming GeForce Special Event on the 20th of September.

KitGuru says: Considering eight PCIe 5.0 lanes offer the same bandwidth as 16x PCIe 4.0 lanes, don't expect to run into a bottleneck using these cards. Still, that's only as long as you use them on a PCIe 5.0-compatible system. If the system is limited to the PCIe 4.0 standard, the maximum bandwidth would be cut by half, which may become a problem.
