You are funny. 0.7V is the idle voltage, not in a million years you'll see 4.5Ghz full load with 0.7V. As for scores, given that zen 2 has ~5-10% higher IPC than Skylake and 5.3Ghz of the 10900K is 14% higher frequency than 4.64Ghz of the 4700G and 4700G is 7% behind in score, this means Zen 2 implementation in 4700G has ~7% higher IPC compared to Ice Lake, as expected.

Ice Lake has a much higher IPC than Zen2.

You can check AT review on this topic. Ice Lake is on average about 10% better IPC than Zen 2.

I doubt it maintained 65 W envelope while overclocked. ASRock is known for fudging power numbers (feeding lies to the processor to trick it into drawing more). I imagine it wasn't running on a public, production BIOS. In general, you really have to be careful when performance testing processors as motherboards can pull all sorts of dirty tricks that screw the results.

Depends. According to specint/fp Ice Lake has less than 10% more IPC compared to Ryzen 3000 desktop on average. But Renoir has much lower DRAM latencies. So, especially desktop Renoir could have a some IPC advantages over Ryzen 3000 desktop. Which decreases the IPC gap to Ice Lake.

Initial benchmarks for the Ryzen 7 4700G are here, AMD's upcoming 65 W Renoir desktop APU. The Ryzen 7 4700G has been shown to offer upwards of 25% more performance than the Ryzen 7 4800H while being competitive against the likes of the Intel Core i9-10900K.
