Question Zen4c vs E core Die area.

[Mopetar]

You are excited about every Intel move, does that mean they pay you?

edit: BTW I've already written this once, and I'll write it again - I like your trolling style xD. You're aware that we all know you're trolling, yet you continue without changing your tone, staying true to that role.

What's that old saying? It starts with something like "Don't attribute to malice that which. . ." It's not nice to go around assuming someone is a troll!

I will put it as nice as I can. He loves Intel so much, he ends up looking like a cheerleader for them.

Maybe he is sitting on a hot Intel CPU. Every time it heats up, he goes "weeeeeeeeeeee!!!!!".

AMD won't cut it for him. It only goes up to 95C. He needs his 100C fix.

He's a troll, fully aware of what he's writing. It's not about love or anything, but like any troll, he feeds off your reaction. He couldn't care less about Intel; your reaction is what matters to him.

Trolls tend to be clever, not dimwits.

Saw some discussion about it before either in this thread or another one here, so let me just highlight what's talked about past 4:50. Zen 4c can clock over the 3.1GHz boost we see on Bergamo, it just ends up less power efficient past roughly that point than Zen 4 is at the same clock frequency. The higher you go then afterwards, the larger the gap is, with Zen 4c taping off closer to the 4GHz mark than the 3GHz one.

No single mention of the so far MIA little phoenix. They think the possibility of mixed Zen/Zen c cores hybrid chips will appear next gen.

Yup, 96C Genoa max boost clock either isn't more than 3.7GHz. For mobile AMD should use hybrid design where regular Zen-cores are used to boost levels achievable within TDP and 4c cores for low loads and multicore loads where better clocks can be achieved with 4c cores. Probably resulting 2+4 configuration for very low TDP(under 15W) and something like 6+8 for 35W. For high tdp mobile parts there is need for c-cores for only low load cases so configuration like 8+2 should be preferred. Those configurations are already in use with ARM-designs - and somehow with Intel at low tdp configurations. For desktop bringing 4C cores instead of regular 4 cores would be just plain stupid thing to do.

Very interesting. Saw that video on my rec feed, but just thought it was fluff. Going to go watch it now, thanks.
Zen 4C being more efficient than Zen 4 until ~3 GHz is interesting. 96 Core Genoa, has an all core boost of ~3.5 GHz, so there definitely seems to be an intersection where equal core count Zen 4 and Zen 4C chips might have Zen 4 vanilla being more power efficient. But I suppose the beauty of Zen 4C is having more cores.
4GHz being around the max clock means it is only ~70% the Fmax of Zen 4 vanilla. Gracemont in RPL seems to be up to 4.3 GHz, according to TPU.

never ignore a video where a wild gordon is.

Yep, checks out what with the different track options and/or cells they used, since technically those are more efficient at some point when actually switching.
