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.

In the Digital Foundry Spider-Man Remastered PC video, Alex goes into why the game is so CPU dependent and he directly asked Nixxes and according to them, it's because "BVH building is very expensive and the extra cost on PC of decompressing game assets from storage into memory."

I think it's similar in many ways to how the CPU and GPU work together to render a frame. The CPU sets it up, and the GPU executes. It's the same with ray tracing, in that the CPU sets up the BVH while the GPU executes.

I see, thats possible i guess, thanks for sharing the vid, will watch it later

Aside from the 13900KS, aren't those all just rebranded Alder Lake though?

How is MacOS able to boot on Raptor Lake but not FreeBSD?

Three cheers for Theo de Raadt (or whoever) making sure that OpenBSD can boot on Raptor Lake!

More expensive than +20%?

The 5700X is $250 on Amazon right now, and it will go even lower after the Zen 4 launch. If you think Intel is saving some bucks by skipping the small Raptor Lake die, wait until you see just how competitive AMD can get with a 80mm2 die on a cheaper node.

The IO die is not free. Shipping it to final assembly is not free. Packaging the whole thing is not free. Validating three to four individual parts is not free.

Monolithic is a pain from a yields perspective, but MCM has its own problems. The only advantage is optimizing leading edge node usage.

FYI, the 5700X just hit $200 in the US market, and the 5600 is hovering over $140. The comment I made about AMD being potentially able to exercise pressure on Raptor Lake pricing using the cheaper AM4 platform was on point. Intel needed to walk a fine line with RPL die size and pricing, and apparently they thought so too.

I've seen (some) people complain that Intel's desktop value segment isn't getting Raptor Cove. I expect the criticism will fade away once we get to see the price/performance ratio of 13400 and 13500.

12600K on Z690 board seems to be choosing multitude inbetween frequencies between the minimal and maximal frequency depending on load.

Raptor lake CPUs seems to be switching just between e.g. 1100 and 5500 MHz, with nothing in between.

Is this how Raptors behave generally, or only on Z690 boards, or does it have something to do with my BIOS settings or Gigabyte BIOS or why is it happening?

 

[Kocicak]

I got an AIO back to be able to test the current 13900K well and I tested the effect of hyperthreading turned on and off. I hoped it will have some decreased power consumption effect, but that happened only for the highest multithread load. Turning the HT off only affected this score, it had no negative effect below that.

Is there any benefit in turning HT off?

I also tried to overclock it to 6000/5800/4300 MHz, changing the settings to 5500/5500/4500 and lowering the voltage enabled reaching better multicore score with 65W less power and up to 25% power draw reduction at lower loads.

Hyperthreads are the lowest priority for Thread Director, behind the E-cores, so it makes perfect sense that disabling hyperthreading makes no difference in all but the most heavily threaded workloads.

The 13500 is looking very good based on this leak from Videocardz. P cores boost as high as 4.8Ghz @ 1.2V for ST and as low as 4.4 Ghz for all-core, meaning in general usage we're likely to see 4.6Ghz. Meanwhile E cores stay at 3.1GHz for all-core, great for efficiency.

All I need to see now is ring bus speed and price. If this gets priced significantly cheaper than 13600K it will seriously compete for the value crown with the 13400.

 

[Hulk]

Raptor Lake Refresh this summer supposedly. Process refinements said to increase clocks 100-200MHz. Anyone have any additional info?

Unlikely that soon but there's always the 13900KS.

2023 could see the first ever KX SKU from Intel: KS based on RPL-R.

Yeah, with additional 8E cores, 13500 series are much more competitive with upcoming R5-7600. Not to mention the total amount of L3 cache has been increased from 18MB to 24MB; although still less than 32MB of 7600...

13900KS specs (as well as the 13900 and 13700). The 6 Ghz is only TVB.

Edit.

I mentioned a while back that the 6 Ghz numbers was going to be for TVB only and people did not agree.

Strange. Intel's fastest CPU's have employed TVB for top clock since Rocket Lake? Why think that wouldn't be the case I wonder?

I remember back then(before Zen4 was released but info about 6 Ghz boost Raptor Lake was being released) I mentioned that the 7950X and 13900KS will have the same max boost speed(5.8 Ghz vs 5.8 Ghz) and that the 6 Ghz was only applicable to TVB. Many people did not believe that.

Anyone able to break 2200 on CB R23 ST? If so, what settings get you there?

 

[Kocicak]

Well, if you give it volts, it runs... The question is, for how long. This is my current CPU from 18th November.

At this moment I run it at 6000/5800/4400 MHz with auto voltage, but I dont have courage to stress test it. But it has not crashed yet with light everyday load. When I run 4 threads of Cinebench for a short while, it feeds in 1.360-370V (running at 5800 MHz).

Whoa! Big number there!
What are your BIOS settings that make it hold that frequency? I cannot get my 13900K to hold anything faster than 5.5 even though the temps are fine ST?

 

[Kocicak]

I think your BIOS is buggy, or you have some too restrictive setting on by accident. At least on my motherboard I got over 2200 at stock settings every single time.

BTW you cannot run any monitoring software the same time you test for the highest score. You need to close all task managers and HW infos etc. first!

 

[Hulk]

I always get the same score, ~2150.

Are you setting the P core frequency in the BIOS?

[Kocicak]

2150 is 5500 MHz score. I set everything in BIOS. I tried using Intel extreme tuning utility but I got rid of it quickly. Weird things were happening and I did not have mood to investigate, what exactly is going on.

In stock setting you should see one or both best cores running at 5800 MHz running all the time during 1 thread run.
