Can i take the alternative timeline intel 13th gen where that 16e core space is taken by an aditional 8 pcores instead?
You can, its called AMD.
I just do not get it, the 12600, 12700 and 12900 all with e-cores made a significant difference against the very best AMD has, in fact the 12600 with only 4 e-cores manages to hang with the 5800X! 8 full fat cores with hyperthreading vs 6 full fat cores, hyperthreading and 4 - e-cores...go figure. And the 12600 and 12700 all versions from non k upwards are driving performance efficiently. the 12900K and KS are the halo products and can and will suck a lot of power but in the low to middle the power efficiency vs performance is stellar. The e-cores in a desktop environment with Windows 11 runs fantastically well. The e-cores handle all the background tasks with ease, in fact it's so seamless you would never know and then the P-cores come in for the heavy lifting and even then if required the e-cores help out even more.
This is not to say the hybrid approach is perfect but it has given Intel a massive performance improvement from the crud that was 14nm in the 11th gen where they have taken back the lead especially in productivity workloads and a lot of us do use these workloads across encoding, rendering etc oh and yes I game as well . AMD on the other hand have there own highly efficient solution with the advantage of a long lived platform that works extremely well. The key is that we have a choice, a proper choice now that AMD socked it to Intel and made them compete. Not sure what the issue is on e-cores but more than impressed on my workloads with the 12700K and I now have more performance than I even I expected which only bodes well for the longevity of this CPU before I upgrade in 5 odd years to whatever is best at the time..
Raptor Lake with 8 P-Cores of the new Golden Cove type and 16 Gracemont e-cores with a higher cache at the top end will be interesting but it will be the halo product, the 13400, 13600 and 13700 will be the interesting ones and we will soon see how well that pans out but it is Meteor Lake that really matters as it is on the new N4 process node with a 40% lower power consumption and low and behold they are going the chiplet route ala AMD (though it will be the new 3D Foveros platform that will make or break Meteor Lake)...Looking forward to see if they can pull it off...
The brilliance of their big little implementation is unfortunately heavily hampered by the node they're baking on, and the fact they haven't moved to a chiplet approach yet. Its a bit of a chicken/egg conundrum if you ask me. Without the ancient technology that this architecture is built upon, the necessity for it pretty much evaporates, and this is shown live and direct by the direct competition.
Another perspective, though, is that the ideal product would marry both concepts: chiplet with interconnect, and several core designs next to each other. In both situations though we're looking at something that can clearly use refinement. But the strides that AMD is making on their chiplet end of the line, are much bigger per generation and over the course of Ryzen versus the samey-timed Intel releases.
It remains to be seen what truly is better. One thing is absolutely certain: the REASON these E-cores extract an advantage right now, is because these CPUs are barely ever pushed to their limits. You quite simply can't, you either run into its retarded boost limit Wattage cap, or you run into a cap you set for yourself after having met 241W once, or you run into heavily reduced clocks. Intel made a great CPU for low intensity consumer segment, but a shite CPU otherwise. This extends to gaming: gaming is a pretty light load, not parallelized at all, and barely loads cores fully, if ever. Not a huge surprise that ADL works for it and the E cores help a bit on background load.
Another aspect in this race is often forgotten: yields and production cost. I reckon AMD has a MUCH higher margin on Ryzen chips than Intel will ever get on their ADL line and followups. Fact is, they're still building monolithic chips and they make them per segment. Ryzen is just a slice of EPYC. And an underlying aspect in that, is that power consumption is going to matter. If you can't keep shrinking, you must go wider. I think the next GPU generation will drive that fact home for us. 450W on top end ADA...
