Raptor Lake Leaks + Intel 4 developments

Last edited:
Zen 3 is winning on power consumption, but I think the 12700K wins overall, since it runs cooler at stock settings using the same cooler:
https://tpucdn.com/review/intel-core-i7-12700k-alder-lake-12th-gen/images/cpu-temperature.png

The other factor to take into account, is that the 12700K has more overclocking headroom, but only if you have a very good cooler.

I expect all of this will seem irrelevant by the end of the year though.

Looking at the trouble people have had cooling the 12900K and KS, do you reckon there will be any coolers that can cool an 18 core Golden Cove CPU, aka 'Alder Lake X'?

Because if not, that pretty much means they would have to be clocked down somewhat.

I'm assuming it would be 18 cores (or more) as the last few enthusiast generations have had this many.

The IPC is the same as the 5800X:

Would need to check Cinebench R20 to be 100% sure though.

Single threaded performance is generally slightly worse, because of the lower clock rate.

Performance is generally only better in games.

If you can clock it at the same or higher clock speed, it should be a straightforward increase in performance.

I find it strange that there isn't more excitement for Meteor Lake. I suppose people generally want the thing just around the corner, not necessarily the thing after that.

Everything I've heard from Intel sounds positive so far, and things appear to be going according to plan. Intel has a shot to take on Zen 4 with these CPUs, and potentially any improved versions like Zen 4 with additional cache.

Notice the difference in the quantity and detail of the information that Intel has released for Raptor Lake and Meteor Lake.

Judging by what they've said, which do you think they are more excited to release?

I get the impression that for Intel, the release of Sapphire Rapids (and possible Golden Cove enthusiast CPUs) is going to be a more important release than Raptor Lake.

As which will launch first, Raptor Lake or Zen4, that remains to be seen.

To simplify this, Raptor Lake is not going to use a new architecture, Intel never claimed that would. Zen 3 > Zen 4 is by definition.

Intel has not mentioned 'Raptor Cove' at all. Even if this were the name, it would be inconsistent with how they name their microarchitectures. The architecture has a different name to the name of the generation.

Also, Intel does not design new desktop microarchitectures on the same node. The exception was Rocket Lake, which was kind of a desperate move, and came as a result of the many delays to their 10nm process technology for desktops.

It's notable that Rocket Lake's microarchitecture was called Cypress Cove (Not Rocket Cove, which sounds kind of silly).

Just like Zen 3 to Zen 3D with more cache is not a new CPU architecture. Raptor Lake appears to be Golden Cove with more cache and improved clock speeds. Additionally, 8 more E-Cores.

Yep, Intel said RPL is compatible with existing ALD boards but never mentioned DDR4, Wouldn't surprise me at all if DDR4 was locked out completely.

I think DDR4 + 13th gen CPUs will still work on the 600 series boards, but they just won't bother with DDR4 for the 700 series boards.
 
Interesting if true. Calling it 'Alder Lake-X' would be a pretty glaring error, if they release it alongside the 13th generation of Intel CPUs.

I think a 12/16 Golden Cove only product would do well with gamers and enthusiasts. But it's clearly come too late, as it's going up against Zen 4 CPUs.

The quad channel memory would be a very nice thing to have though, especially if the memory controller can run at full speed /1:1.

Intel hasn't confirmed a 1:1 DDR5 memory controller config for the 13th generation either though. It definitely seems to be something they don't want to draw attention to.

Yes, he's a machine, Intel model Dave2150 from the future, sent to save us from AMD's thinking machines :D

Just gonna point out once more that Intel's 7nm was delayed. This is the fact that needs to be grokked I think, before speculating on what they will release this year.

The point I was making there is that whatever Intel had planned for 2022 on their 7nm EUV process, it got shelved when they ran into problems with it.

So after the 12th generation release, anything else they release this year hasn't been part of any multi-year plan, nor is it an enviable position for Intel to find themselves in.

Intel: Sorry, But Our 7nm Chips Will Be Delayed to 2022, 2023

In an earnings call, Intel CEO Bob Swan said the company identified a 'defect mode' in the 7nm process that resulted in 'yield degradation' when manufacturing the chips.

I got it a bit wrong actually, Intel's 7nm chips were originally planned for Q4 2021!

The reason for the delay was "the company identified a 'defect mode' in the 7nm process that resulted in 'yield degradation' when manufacturing the chips".

Any time you want to concede that I have a point is good :D

It's still Golden Cove cores, but they will be clocked higher, just like the 12900KS, but also have more cache. Main perf. difference will come from the increase in E-cores. Power usage is going to be significantly higher than Zen 4, especially compared to the 16 core model they demonstrated running at a TDP of 170w.

Intel is heavily investing in Meteor Lake / 7nm EUV CPUs, Raptor Lake was never the plan for 2022. It became the plan when the new Intel CEO took over (maybe few months before), who has barely discussed the 13th gen at all, but said quite a bit about Meteor Lake.

It's only a good idea if people want to stay on DDR4 for a bit longer, and already have a LGA1700 board. I'd maybe consider it worthwhile if the current 12th gen CPUs sell for a good price.

More 13900k leaks, this from an ES3 engineering sample which is able to do 5.5ghz single core.

The owner of this chip says the max single core is 5.5ghz, in multicore the max the P cores get to is 5.2ghz and max of E core is 4ghz. He says he was not able to modify the clock speed as the chip doesn't allow overclocking

Just saw these results on Videocardz. Less than a 10% improvement in single core performance vs the 12900K or KS, by the looks of things. The all core boost speeds look basically the same as the 12900KS.

I suppose that'll be why Intel didn't mention ST performance on their slide. So, you get a nice boost in multicore 'score', this is pretty much exactly what I thought we'd get.

I think Zen 4 will probably match Intel's 12th gen in ST performance, not sure yet about the 13th gen.
