Raptor Lake Leaks + Intel 4 developments

1. You don't know if the situation will be better.
2. The compromises you're talking about for the hybrid design will likely have little to no repercussions for the vast majority of users whose most strenuous task is gaming. People aren't bothered about whether it's "cleaner", it's whether it significantly impacts performance.

It's a case of assessing the situation once both are available.

I think it's probably logical to assume that Zen 4 will be faster over 8 cores (in multithreading tasks), vs Raptor Lake (because apparently Intel are not increasing the P-Core Count above 8).

The fact that they aren't increasing the P-Core count seems significant, as it suggests that the design is still geared towards laptops (not desktops so much), where E-Cores are often favoured.

Single threaded performance is what we need to know for Zen 4. I've heard rumours like 20-25% IPC increase vs Zen 3, but that's all they are for now, just rumours.

It really suggests they can't sort their power issues out so have to bodge on E cores.

Only solution would be moving over to 7nm EUV, Intel has known this for years now (last CEO commented on the problems with 10nm a while ago).

Intel doesn't really discuss the problems with 10nm now, but it's quite a mature process at this point. I think they've already squeezed all the efficiency they can out of it.

Meteor Lake is Zen 4's competitor, not Raptor Lake. Intel has every chance to do well with Meteor Lake, given that it's a new design, with a fabrication technology that is estimated to overtake 5nm EUV in terms of transistor density (hence Intel's insistence on calling it 'Intel 4').

They're not though are they? Intel confirmed similar performance per clock to Comet Lake cores, but at a lower clock frequency.

Maybe they will be redesigned, for Raptor Lake, though?

Alder Lake's 'E' cores (Gracemont) are already 104% IPC of Skylake (Cometlake). Raptor Lake features gracemont 'enhanced' cores, which will have improved IPC again.

And without the clock speed and hyperthreading, Gracemont's real world performance is about 60% of a Skylake core. Oh, and nobody's ever said, leaked, hinted or spitballed anything about improvements to Gracemont for Raptor Lake. Golden Cove yes, but not Gracemont.

So cite your sources Dave m'lad, otherwise this is going in your usual trolling trash pile alongside all that Rocket Lake nonsense.
 
12900KS launches April 5th, two weeks before 5800X3D. I wonder if this will impact RPL (13900k's) release date? Q3 still the latest rumour, I imagine both Intel and AMD will want 13th gen/Zen4 out first. Exciting few months to come!
 
Nah, the 12900KS will be very short lived (it's really scraping the barrel). Intel has every reason to rush out their 13th generation before Zen 4 is released.

Intel will need CPUs (unlocked or not) with 4.9/5ghz turbo speeds on all cores to stand a chance of coming close in performance.

The most positive thing I've heard about Raptor Lake so far, is that Intel are making the transition to (only) DDR5 with the 700 series chipset motherboards:

Hopefully, that will mean higher frequency RAM support, with the ability to run DDR5 memory with a memory controller gear of 1:1. Not adding this to Alder Lake DDR5 boards was a significant drawback (as DDR4 at gear 1 is often faster in tasks like games).

Intel is probably feeling pressured by AM5 / Zen 4's support for DDR5, which probably won't have any limitations on the memory controller speed (AMD has never had an option to lower the memory controller speed with Ryzen CPUs).

So Raptor Lake motherboards will be DDR5 only, but Raptor Lake CPUs still have a hybrid memory controller for backward compatibility with DDR4 motherboards. But the hybrid design is still flaky so you're not getting the benefit anyway.

Good job as always Intel.

Maybe the boards will also support meteor lake which is only going to have a DDR5 controller.
