I can't for the life of me understand why Omen would pair an APU with a high-end video card. There is literally zero reason to do so.
Sure, an AMD APU will have one of the most potent IGPs in the world but it's rendered completely pointless when paired with a dedicated video card, especially one that's high-end. In fact, I would even say that it's worse than pointless because AMD G-class APUs have reduced ALU performance compared to AMD's mainstream CPUs (standard, X and X3D).
This is because AMD uses inferior ALU silicon in its APUs because they're made for people who aren't into high-end gaming or anything really demanding on their hardware. People who fit this profile would benefit far more from the power savings incurred by using an IGP instead of a dedicated card. I refer to tasks like this as "Boomer Tasks" because this is what most Boomers do on their PCs. Checking emails, using Facebook (including Facebook games like Farmville). Since the use of the AGP increases power draw and heat, there's no reason for AMD to use silicon that can clock higher than what the extra heat allows and so the performance ceiling is lower and this will hurt gaming performance.
It's not like anyone could even say that the APU's IGP is a "just in case" thing because all standard-line AM5 CPUs have IGPs already but they're tiny glorified video adapters which means that they have no negative ALU performance impact.
To most enthusiasts, this isn't exactly rocket science, it's common sense. Just the fact that Omen would offer a PC with specs like this strikes me as incompetent at worst and cynical at best. Will it work? Sure it will, but the video card will long out-live that APU.
I think that HP probably got the R7-8700G for a seriously low price. The R7-8700G seems like a product that AMD probably shouldn't have bothered making in the first place. I can't imagine that there's a huge desktop market for 8-core CPUs with reduced ALU performance caused by a world-class IGP. The price itself is actually not bad but I would personally rather have the Ryzen 7 7700 for less than $9 more.
