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.

So you're saying he should change his name to CarpFrameX given how fishy his numbers are?

Well, PCGH is a quite commercial site whose part of the content is behind a paywall, they get quite some money from announcers among others Intel, as a hint they got a 13900KS to play with while Computerbase apparently got nothing despite good relationships with Intel as well (since they got a dual Xeon 8xxx server for free)...

 

[Mopetar]

Almost no one got a KS because it's really not worth buying over a 13900K unless you absolutely want that last ~2% performance and don't care about the cost. Why widely sample something for review if you know that the result will be a collective "meh"?

3 bins on fully operational 13900's when you consider the KS, the K, and the non K.
They should just make like 10 bins and price accordingly. 13900A (choice, the best), 13900B (next best), etc... It would stop a lot of the returns to get "a good one."

Hmm, I thought that running only one company's product with overclocked memory and overclocked CPU while leaving the other at stock CPU and dog slow JEDEC memory was supposed to be evidence of clear bias and that their results couldn't be trusted. Seems no one has an issue with it in this case though. Strange .

But he is testing the 13900k with just 5600, there is still a massive gap. You can even drop the 13900k, the 12900k with 4400 is basically matching the best zen 4 has to offer.

It is known that RPL > ALD >>> Zen 4 for gaming. Dunno why it's still contestable

13900K and hot spots. As most of you know I have a 13900K with a 280mm AIO. In some applications I can run nearly 250W and not throttle, like Cinebench or Prime 95, which seem to load/heat the CPU evenly. But in others, namely, Vegas Pro 19 while using Render+ to render I will throttle at 200W. Render+ frameserves the Vegas timeline to an external x265 encoder. It's a quite compute heavy process as Vegas is assembling the timeline, which is then served frame-by-frame in uncompressed video form to the external x265 encoder.

But apparently it loads some cores more than others and thus causes hotspots, which causes throttling.

I've tried a number of things to get to a "set it and forget it" approach so that I'm good for any application and I think I've found a good setting that I wanted to share here.

I have set by core usage to 5.8GHz for 2 cores, 5.5GHz for 4 cores, 5.2GHz for 6 cores, and 5.0GHz for 8 cores. I've also capped the E's at 4.0GHz. The reason being if an application is using more than the 8 P threads then it's probably using a lot of the 16 E's as well so I might as well keep them a little cooler for a small reduction in compute.

So it's working well. I can still put 37K in Cinebench, get to 5.5GHz when processing fx in Photoshop, and the CPU stays 86C max while rendering in Vegas Pro.

I currently have PL1 set at 225W but in with my current settings it only pulls about 180W in Vegas Pro, which if the cores were left "uncapped" they would throttle. But holding them to 5GHz stops that hotspot issue.

I think you missed the point of my post.

And no, your performance statement is not accurate in the slightest. Just saying it is, "known", doesn't make it true. Every outlet that I've seen that uses faster memory for both platforms shows that Zen4 is competitive at worst with RPL in gaming and several show Zen4 being pretty darn close (6-8% behind). Zen4 actually takes the lead when talking lower end or lower midrange SKUs (i.e. <$300). Many reviews have already been posted that support this in this thread, so I won't bother repeating them all again.

In any non GPU bottlenecked review the difference is 25 to 30% between Zen 4 and RPL. I can post you a bunch of them, from purepc to club386. And I know cause ive tested myself, a tuned 7950x with 6200 tuned ram ties a stock 12900k with 6000 ram in averages in cp2077 but loses by 35% in minimums. And that's just in the built in benchmark that's relatively light. In game the difference is actually bigger.

But if you don't trust the reviews, I guess we can test it ourselves. I have both a 12900k and a 13900k paired with 7600c34 ram, anyone wants to post a cp2077 or a spiderman run with their zen 4, ill be glad to help.

I would believe that more if it was the 13900K due to its increased cache but 12900K beating a 7950X in minimums with that wide a margin? Hmm...

It could also be just specific to CP2077 and probably this behavior is not representative of other popular games.

You can ask anyone with the 7950x, is struggles to break 70 fps in the built in benchmark, in order to hit anything close to 80 you need to tune the crap out of the ram. The 12900k easily hits 95+, and the 13900k isn't that far better with around 100-105 in minimums.

Smells like an alt account but whatever.

You're talking about 1 - 2 games. I'm talking about on average across a large range of games. If we were to completely cherry pick, I could show the 7950x dominating a 13900k by over 20% in gaming.

AMD Ryzen 9 7950X Hands-On Review

We have tested the AMD Ryzen 9 7950X for about two weeks now and it's finally the time to share the results!

www.tech-critter.com

Using DDR5-6000 CL30 for both systems, 7950X has no issue beating 12900K in BOTH minimum and average FPS.

Im validating PCGH's numbers with those 1-2 games. If they are right about those 2 games, then they are probably right about the rest.

High settings - no RT. Activate RT and everything goes to **** for the amd part.

Do you have a bunch of game review averages where RPL and ADL dominate Zen4?

All of those posts in this thread show average performance across a mix of games. Taking the results from the fastest RPL and Zen4 chip in each review, the differences are below. Across all those reviews, the 13900K(S) was 5.5% faster than Zen4. If you take out the two biggest outliers (PCGH and Eurogamer), the average is 4.6% faster in favor of RPL.



Posting one or two games where RPL truly dominates Zen4 doesn't paint an accurate picture. Just like if people post up the few games where Zen4 dominates RPL. What reviews of a broad swath of games show is that gamers won't be able to tell a difference between RPL and Zen4. Both provide a great gaming experience. I'm even doubtful gamers will be able to tell a noticeable difference with Zen43D even though it will likely bring big performance gains.

Oh yay, this argument again! This should be what, the 4th time this calendar year.

Purepc uses heavy settings in heavy game scenes. And yes, ald and rpl dominate in those. Honestly im too bored to have a discussion about something that is just a fact, so if someone has a zen 4 he can step forward and we can test 5-10 games and see whats up.

I have both a 12900k and a 13900k with 7600c34 ram, so i can test both against a zen 4.

I don't know why people are surprised that a 12900K would beat a 7950x in a CPU bound situation. The 12900K has a 6 wide core, 7950x has a 4 wide core. 12900K also has a ROB that is 60% larger than Zen 4's (512 vs 320).

ADL's main problem was that it lacked the memory and cache bandwidth to feed the cores, but this was fixed with RPL.... though not entirely. RPL still has an insatiable need for increased bandwidth to perform at full capacity.

The problem with that review is that it was done with a 6700xt. Much of the confusion about the extent to how much RPL or Zen 4 is faster in games is due to reviewers being GPU bottlenecked..... typically out of ignorance or incompetence.

So you're saying that the 7950x would be more than 10% faster than the 12900k in their test case if they used a faster GPU?

Im saying... Instead of arguing about reviewers, let's test them ourselves? Isnt there anyone with a zen 4 and a high end gpu? 😁

For example this guy is testing in one of the heaviest parts of the game, at 1440p + rt on + dlss performance, i can upload the same area with my stock 13900k and compare if you like me to

Can you believe it, most of retailers are either sold out or marking up the MSRP on the non K 13th gen. CPU!😬☹

They claim excessive demand right now!🫣
