I am interested in the 8000 series, but I couldn't give a rats *** about any iGPU. They will never be used in my systems. it's a waste of money and I/O as far as I am concerned.
AMD is keeping the same socket, so it is unlikely we will be getting any more PCIe lanes, which is the biggest thing I always hope for for any modern CPU launch, but maybe - just maybe - a new batch of chipsets will emerge allowing me more options on the I/O front off the chipset?
I have two considerations when shopping for a motherboard:
1.) I want to be able to have at least 16x-8x at the same time. Not this bullshit where you have 3 full length PCIe slots and they only work in 16x-0x-4x or 8x-8x-4x. The generation on the second slot matters less to me. I want the primary slot to be 16x Gen5, but I'd be happy if the second slot were 8x Gen3, as long as it doesn't rob the first slot of lanes when I use it.
2.) It can't have any performance reduction compared to other top of the line consumer CPU's.
Both Intel and AMD's more professional solutions right now (Sapphire Rapids Workstation launched several months ago, and Threadripper launched - well - today) are no longer HEDT. HEDT was the no compromises philosophy. The x58, x79, x99 and x299's for the world. They were every bit as fast as a top of the line consumer CPU, but just added some professional features, like more PCIe lanes, more RAM channels, etc. My i7-3930k overclocked to 4.8Ghz and in doing so kicked everything else's *** on the market for years, while giving me quad channel RAM and 40 PCIe lanes.
Now you can get these lanes, but only if you buy Sapphire Rapids WS or Threadripper, which are lower clocked than their desktop counterparts, and use registered RAM (since it is no longer socket compatilbe with non-registered with the introduction of DDR5) which absolutely kills performance.
I want a 14900ks or 7800x3D or 7950x3D with fast low latency unbuffered RAM, but with 35-40 PCIe lanes and (maybe) quad channel RAM.
And since I won't be getting that, at least for some time since both Intel and AMD are married to their current sockets without seemingly any intent of adding more pins for more PCIe lanes, at least I hope that chipsets will be added that will allow me to use more expansion.
With PCIe Gen5, the bandwidth is there. There is no shortage of bandwidth. I just need it spread out over more lanes. PCIe switching (wither in the chipset or separately) can help here. I'm probably going to be let down on this front, but I am hoping something appears in the 8000 series chipsets that allows for this.
