I agree the 8mb Cache is what is limiting performance.All apu's up to this point have been monolithic. There is a sacrifice if cache because of this. Thats a lot of transistors. We also inow one of zen 3's bug uplift comes from its largr unified cache.
It makes sense. We likely wont see a multichip approach for apu until zen 4 and mcm for navi 3.
Yes, it seems strange AMD could dominate the entire laptop market yet don't have much of a presence to speak of. Hopefully there will be more options soon. Asus had an exclusivity deal with AMD that was for 6 months. That should expire soon. But it was only for the 4800hs. Which, TBH, is the chip I'm more interested in. Ideally, AMD will release a 5700HS soon with even greater gains over the 4800 and will actually get that chip into a wider variety laptops.There's hardly any Ryzen 7 4800U laptops to actually purchase. Are they even making more or do we wait a year? lol!
Depends on an hardware picked. I've seen a lot of Asus & HP laptops while others seems to be lacking a bit. I am surprised if your supplier cannot get a specific one you want, did not offer you a replacement.In the meantime, in our company we are still waiting for delivery of six 4700U laptops, because our supplier cannot get stock. This all seems a bit pointless unless AMD can get more chips out of the factory doors.
Ah, I think it just has higher clocks, not higher IPC. Geekbench 1172 vs 1500+ on Tiger Lake and 1700 on the new Apple M1. So the 5700U is a last gen part with a next gen model number => sneaky marketing. Even the multi-core looks lackluster since TGL gets nearly that with 4 cores. This chip is Zen 2.So it definitely has higher IPC than Renoir, judging from the single-threaded score, but it's not as good as Vermeer. Maybe this is some sort of hybrid of Zen 2 and Zen 3?
But that is exactly the point I'm trying to make. Single core clock speed only increased by 2.4%, while performance went up 13.7%. There must be something else at work here, since we should be able to assume that each APU was able to sustain its single core boost clock throughout the test.Ah, I think it just has higher clocks, not higher IPC.

Tiger Lake (1185G7) has some weird behaviour in this test, showing 22% higher IPC than even the 5700U and a massive 35% more IPC than the 4800U. That is far more than we should expect on average. In AnandTech's SPEC results, Tiger Lake doesn't do this well at all clock-for-clock. Multi-core scores shouldn't even be looked at, because we don't know what TDP the CPUs were running. Intel was very happy to promote Tiger Lake at 28W, so we should expect that the samples that had a 6000 score were running at that TDP.
