Uhm, "more than Intel" != enough.
So I get that 8CU might be enough for casual gaming but then I would not want it paired with a dGPU. What other work then gaming (or graphic content creation perhaps) needs more than, say, 2 CUs?
Video editing it helped by extra CUs to a certain extent.
But what if, like me, you want raw CPU and IO but not graphics?
IO on a laptop is always limited. Even on huge chassis you might get 2x 2.5", 2x M.2 SSD, M.2 WiFi, ODD, and dGPU. That's it as the form factor doesn't allow for more. "All of the CPUs are PCIe 3.0 only, rather than PCIe 4.0 like the desktop parts. This is primarily due to power – the double bandwidth of PCIe 4.0 requires more power, and given that storage or graphics rarely need peak speeds, AMD felt the product portfolio would prefer battery life in this regard. Each chip has sixteen PCIe 3.0 lanes, split such that x8 is available for a graphics card, and two x4 links for storage. There are separate PCIe lanes for other modules such as Wi-Fi 6 or mobile network access (4G/5G). Display support for the CPUs allows for two 4K monitors through DisplayPort over Type-C, an additional 4K monitor if Thunderbolt is used, and a fourth monitor if USB 4.0 used. AMD has designed Renoir to not need additional chips to detect which way a Type-C is connected – that is all handled on die. With the display and USB support, the processor allows for concurrent USB 3.2 and DisplayPort use, with the peak DP v1.4 8.1G HBR3 standard in play using display stream compression (DSC)." There isn't much more on the IO that can be done after that.
In terms of CPU grunt, this is a Zen 2 CPU which has a ton of power as it is. Clock for clock it should be the same performance as its desktop cousins. If you need more power and IO than that, then you need to be on a desktop or HEDT platform.
