How many cores needed to match current Intel Macs

[t0mat0]

How many CPU and GPU cores of M1 strength, would it take to match the current Intel Macs?

Geekbench, or preferred benchmark (Number of 8k streams, XCode compile time etc)
16" MBP with AMD Radeon Pro 5600M with 8GB HBM2 memory
2.4GHz 8-core 9th Gen Core i9

iMac Pro with Radeon Pro Vega 64X:
iMac Pro 10-core
iMac Pro 14-core
iMac Pro 18-core

Mac Pro with 1x or 2x Radeon Pro Vega II Duo:
Mac Pro 8-core
Mac Pro 12-core
Mac Pro 16-core
Mac Pro 24-core
Mac Pro 28-core

Only Apple knows for sure.

I can say that the 2.3 GHz Core i9-9880H in my 16" MacBook Pro is within 5% of the M1 in my Mac Mini on CineBench and x265 transcoding.

Radeon Pro 5500M with 8 GB RAM still kicks the M1 GPU's butt, but considering the M1 is 20W for CPU+GPU+chipset+RAM, while the MacBook Pro has a 45W CPU, 45W GPU, plus chipset, plus RAM, it's far closer than it has any right to be.

I would imagine (pure speculation) that a 16-core GPU with a 40W thermal budget could probably beat the Radeon Pro in the MacBook Pro. Even paired with the current 8-(4+4)-core CPU. And that's the current generation M1 GPU.

An M2? I fully expect the M2 to be available in three versions:

M2 - 8-core (4+4) CPU, 8-core GPU, 20W - basically the same as the current M1, but with slightly improved cores on both CPU and GPU, and better "chipset" functionality, allowing for no compromises comparing to the current Intel 13" MacBook Pro and Intel Mac Mini.

M2X - 10-core or 12-core (6-8 high-power + 4 low-power) CPU, 16-core (maybe optional 20-core) GPU, 40W - For the mainstream iMac, the 16" MacBook Pro, higher-end 13" MacBook Pro, and higher-end Mac Mini.

M2Z - 16-24 core CPU, 24-32 core GPU, 100W. For the iMac Pro and Mac Pro. Maybe even dual-socket design available. Maybe the GPU on a separate board with its own separate 100W power budget and separate RAM. Super bonus points if they bring back a truly high end Mac Mini with this one for server farms - grille front and rear instead of solid for full-chassis pass-through cooling.

Names are up for debate, I'm just basing them off Apple's previous iPad CPU naming.
