Question Raptor Lake - Official Thread

[Hulk]

Since we already have the first Raptor Lake leak I'm thinking it should have it's own thread.
What do we know so far?
From Anandtech's Intel Process Roadmap articles from July:

Built on Intel 7 with upgraded FinFET
10-15% PPW (performance-per-watt)
Last non-tiled consumer CPU as Meteor Lake will be tiled

I'm guessing this will be a minor update to ADL with just a few microarchitecture changes to the cores. The larger change will be the new process refinement allowing 8+16 at the top of the stack.

Will it work with current z690 motherboards? If yes then that could be a major selling point for people to move to ADL rather than wait.

Is Raptor supposed to have higher IGP perf?

It should be mostly unchanged. Rumors point to the same number of Execution Units, but running at a 3% to 6% higher clock speed. In other words, you won't probably notice the difference.

It looks faster to me.
Shadow of the tomb Raider dx11 at 1080p lowest gives 28 fps. 27 on ddr4. And with a oc to 2100mhz it jumps to 35fps. Thats more than a 3200g if i remember well.

So RPL-U/p/H the major change is integrated DLVR. Hopefully that makes the chips more efficient. Performance of ADL-U/P was never an issue. I recently purchased a core i3 ADL-P laptop (for $350) and performance is very good.

So RPL-U/p/H the major change is integrated DLVR.

It would appear to be so.

 

[Geddagod]

Still too early to say. Raptorlake plans would have been set in stone years ago. It's not until Meteorlake part of the changes start to apply. I assume until then a good management just prevents things from getting worse.

Even Meteorlake should only have a partial effect from new management.



They might as well go all the way.

4x 34 core MCC die Emerald Rapids-AP. Maybe 4x 24 core Emerald Rapids for regular chips?

4x34 or 4x24 would be crazy, but didn't Intel themselves just call Emerald Rapids a minor upgrade, not really a major uplift.
4x24 would be 96 cores, just as much as zen 4 Genoa. IPC between raptor cove and zen 4 is pretty close as well. I still expect Intel to consume a lot more power though because of node diff

I can't see the post, can you post pictures of it?

I don't speak Korean. How about you tell us what it is that is exciting about this.

 

[Kosusko]

I don't speak Korean either. My understanding is that if you are rendering on screen then all 24 cores and 32 threads are involved. If you hide the rendering in the background tab, it renders only all 16c/16T "Raptormont" E-cores and 8C Raptor Cove P-cores are ready, e.g. to play the latest game.


"Raptormont" = Gracemont

16C/16T Gracemont Cores rendering would be like having a last gen 8C/16T CPU or recent 6C/12T CPU.

 

[Markfw]

Exactly why I hate BIG.little.

 

[Kosusko]

Some may be drawn to the tech enthusiast by its hybrid composition of CPU cores and development that takes place at the level of OS planners (paradigm shift) - in contrast, the competitors' processors are boring backwaters.

Everyone is the master of happiness in their choice.

When BIG.little works the way it was intended, maybe I will be interested, but not the way it works now.

The Thread Director Trick that will be found on Raptor Lake could also be backported to ADL and AMD could also(I don't see why) do something similar on 7900X and 7950X with multiple chiplets, one CCD for Gaming and the other for Rendering Jobs?? That would accomplish the same thing.

 

[DrMrLordX]

If you hide the rendering in the background tab, it renders only all 16c/16T "Raptormont" E-cores and 8C Raptor Cove P-cores are ready, e.g. to play the latest game.

So it has the same flaw as Alder Lake. Ugh. Was hoping they'd fix that.

Stop! I can't drink right now!

A site called OCbase had some interesting results

https://twitter.com/x/status/1578210243871313921

also there's so many results in its ranking list, include SSE/AVX, with different CPUs like 5950X

 

[Kocicak]

When does the review embargo lift? It seems that Intel may want to push the release of the processors forward.

PR online seller just list Raptor pre-order price

13900k : 773 USD
13700k : 548 USD

Is rated at 35 Watts so it's likely the 13900HX

Sorry if this has been answered, but I can't seem to find anything even when looking at the spec sheets for the z790 boards. If you use the 5.0 SSD connectivity, what do you end up for the GPU? For instance the 4090 is a 4.0 spec. I know you lose 8x of the 5.0 connectivity for z790 if you use the 5.0 ssd, but what does that mean if a 4.0 item is attached? Do you only get 8x 4.0 or do you get 16x 4.0 since 8x 5.0 is equiv to 16x 4.0?

Scenario:

Nvidia pci 4.0 4090 card in one of the 16x 5.0 slots on board and 1 5th gen pci 5.0 4x SSD

Do you end up with:

16x 4.0 to 4090 and 4x 5.0 to SSD

or

8x 4.0 to the 4090 and 4x 5.0 to SSD.

Sorry if this is confusing, just having trouble nailing this down.

I am curious because if AMD released their next gen card with pci 5.0 would it have an advantage in theoretical bandwidth in scenario 2 since it would have 8x 5.0 instead of 8x 4.0?

BIOS update for anyone running ADL available to support Raptor available? Just wondering.
Not available on mine and it's getting close to release for Raptor.

I think it would be 8x 4.0 to the 4090 and 4x 5.0 to the SSD. And yes a PCIE 5.0 video card would get 8x 5.0, so more bandwidth.

I have Z690 and I don't use the second PCIE slot so video card runs at 16X 4.0. SSD is in the 4x 4.0 slot that's meant for storage.

I am not a fan of the Big.Little arch at all and do not like the e-cores at all and I will always shut them off and use them as 8 core powerhouse chips as I am a huge fan of the p cores.

I wonder how much of an IPC increase the P cores will have in Raptor Lake compared to Alder Lake. A lot of consensus said very little and it was mostly higher clock speeds.

Though the below article says 12% IPC improvement over Alder Lake P cores at same clock speed.

https://www.tomshardware.com/news/core-i9-13900k-early-review-shows-big-gains-over-core-i9-12900k

If that is really true, that would scream awesome if it can really clock much higher all cores.

Basically I am hoping for a 13900K, shut off e-cores and clock all P cores to 6GHz all core on a Noctua NH-D15 cooler. That would be a big boost without IPC gain and oh my with 12% IPC uplift would be huge.

Seems maybe 6GHz all core could be doable on NH-D15 with e-cores off given the samples out there that overclock to 8.2GHz on LN2. And the current 12900K hits like 7.4GHz on LN2 and cooling it on NH-D15 at 5/5.1GHz is easy from my experience. Even 12700K hits 5GHz easily to cool on air at 1.275VCORE with e-cores off.

Maybe a lot more clock head room with Raptor Lake P cores??

I though wonder how a Raptor Lake 8 P core part e cores off with ring clock high and P cores 6GHz will do in gaming compared to upcoming 7700X3D?? Given the heat and thermal issues regular Zen 4 is facing already hard to imagine AMD will not have to downclock it a bit so hard to say.
