Intel Xe iGPU performance is impressive; sign of strong Xe dGPUs to come?

Obviously the iGPUs are not nearly as strong as dGPUs, but early benchmarks show huge gains. Hopefully it's a sign that Intel Xe dGPUs will be competitive on the high end.

Some performance metrics from the below LTT video:

Doom Eternal: 1080p ~30fps on Medium settings

Borderlands 3: 1080p 33 fps on Low settings

Shadow of the Tomb Raider: 1080p 26fps on Medium settings

Rainbow Six Siege: 1080p 81fps on Medium settings

 

Just trying to get some clarifications on the performance scores...
iGPU shares memories from the RAMs right? So if larger sized RAMs are installed, the iGPU stands to "share" some of the RAMs' memories right? Does RAM's clock rates affects iGPU performance as well? 3200Mhz is the fastest commercially available option to date. 4266mhz? How's that gonna add additional costs to average consumers since it's not common yet...

 

I'm so surprised of what you can get with what, 5W GPU? a bit off-topic, these 25W AMD processor kicked my 100+W CPU's but in Cinebench R20 bu like 300 points, lol that really piss me off. That much more efficient are AMD mobile processors?
