WirkoShared L2 seems like a bottleneck ....

Prima.VeraThe latest game engines can easily use up to 32 CPU cores with significant performance improvements. We all know how laggy the UE5 engine is. However the more stronger CPU cores, the fastest is runing.

529thHighly intrigued with their X3D counter part

WirkoYou have just described HT. Which also means mixing two types of cores: fast ones running one thread and slow ones running two, even if the "type of core" constantly changes.
As a replacement for hyperthreading, E cores are great.
Then again, they might have their own scheduling issues. If all four cores in a cluster are given hard work, what's the performance drop? Shared L2 seems like a bottleneck but if the cores execute threads belonging to same process, meaning shared memory, it might not be true.

Yes, that's the baddest problem.
There's one thing I still don't understand: can a game direct the scheduler to use certain cores for certain threads or not? Without any additional system utilities, drivers, OS settings?


Very few reviewers/analysts do testing just for science, unfortunately, and TPU is not one of them. W1zzard does testing with more practical value, such as memory scaling and PCIe scaling.

MufasaVAre people gonna repeat this a hundred times to those who won't listen?

At this point people still believe current E cores are for background tasks despite Intel saying they have taken over the majority of workloads.

We can only pressure the big reviewers at launch to have some P core vs E core only and vs AMD normal and dense cores to lay the debate about actual performance of E cores to rest

rattlehead99What benefit do you get from having more than 8P cores that is not a productive/professional workload?
Also their new E-Cores are on par with the last gen P-Cores in terms of IPC, and the clocks seem to be going up as well and now E-Cores will have the same instructions as the P-Cores.
If anything the P-Cores seem to be there just to top benchmark charts.

truerockI'll agree that e-cores are becoming more powerful. But, e-cores are tuned for throughput and parallel processing. P-cores are latency‑optimized, high‑IPC, high‑frequency.
Intel e-cores have smaller IPC as compared to p-cores.

I will say that e-cores - over time - are becoming more like p-cores in functionality.

Upgrayedd32 e-cores?? Give me like 8e, delete the iGPU entirely from the design and use the rest of the space for more P-cores or cache. Why are they even playing around with the market segments AMD has taken from them?

Who at Intel is going. "yeah normies need 64 threads and half of them need to be weaker than the other half". Anyone who actually needs that is just going TR or Xeon. I understand this is a cheaper alternative for some people than TR or Xeon, but the mass majority that will get something like this will NEVER need 32e cores.
