Nvidia AD106, A107 Ada Lovelace GPUs likely to use PCIe x8 interface

The GeForce RTX 4060 (AD106) allegedly achieves a TimeSpy Extreme score of 7,000 points, according to a tweet from resident GPU leaker Kopite7kimi. If correct, the performance of the GeForce RTX 4060 would fall between the RTX 3060 Ti and RTX 3070. Additionally, Kopite7kimi pointed out that Nvidia’s AD106 and more affordable AD107 dies will only have eight PCIe lanes at the instead of 16.

This is the first time we’ve heard of a TimeSpy Extreme performance stat for Nvidia’s RTX 40-series GPUs (Ada Lovelace) from leaked hardware. The AD106 could power the next-gen RTX 4060 and even the RTX 4050 Ti (if Nvidia makes one this time).

That would put the AD106, or rather the RTX 4060, on par with GPUs like the RTX 3060 Ti and RTX 3070, which isn’t a bad thing. The RTX 4060 seems like a nice boost over the TimeSpy Extreme-only RTX 3060. But that’s the problem: we only have alleged TimeSpy Extreme results on a GPU that has yet to be released. As usual, take this information with a grain of salt. However, if history repeats itself, the predicted performance of the RTX 4060 seems to be pretty accurate.

PCIe lane restrictions
The reports of the AD106 and AD107 being nerfed to eight PCIe lanes instead of the usual 16 are perhaps the most fascinating part of the Tweet. We doubt there’s a problem on recent devices if Nvidia uses PCIe 4.0 instead of PCIe 5.0. For example, a PCIe 4.0 x8 configuration for an RTX 4050 or RTX 4060 should be sufficient and provide enough bandwidth for demanding PCIe workloads. After all, PCIe 4.0 x8 has the same bandwidth as PCIe 3.0 x16, and the RTX 2080 Ti – the last GPU supporting PCIe 3.0 – performed well on a PCIe 3.0 x16 interface. The only possible downside to PCIe 4.0 x8 is that older systems are only capable of PCIe 3.0 speeds. As a result, PCIe 4.0 x8 GPUs will be forced to upgrade to PCIe 3.0 x8, which is significantly slower.
