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.

Do you now what is Cinebench, and what is Blender? :grinning:

- Cinebench, just a useless benchmark if you didn't buy Cinema 4D

- Blender is free, and is often used for professional use

So let me summarize. the 7950x is 10% faster than the 13900k at this task, and twice as efficient ? Again, last place in efficiency. No idea where witeken gets his conclusion. Maybe he is from another solar system.

Feeling more and more secure in my decision to pick up a 5800X3D for $300.

From a gaming perspective, this entire gen is kinda a bust. Maybe the hardware is just starting to outstrip the software. If you're on a budget, pick up a last gen part.

7700x3D should regain the top gaming spot without much issue in the next few months.

Fist bump on this take.

I don't encode or run distributed computing projects on my PC, so my 5800X3D feels fast enough at normal stuff and provides really solid minimum FPS in games.

My take on both Raptor Lake & Zen 4: ¯\_(ツ)_/¯

Raptor Lake simply took the motherboard power limit shenanigans and turned it up to 11. Yay.

Zen Master tuning keeps your boards power capabilities in mind (right?) - is there any similar "intelligence" on the Intel side or is melting the power delivery circuits on your board doing the CPU equivalent of Furmark a real concern?

If I was building a new gaming PC for someone today, I'd still choose the 5800X3D. AM5 will mature, and the bestest CPUs for Z790 chipset boards are already released. Looks like 2023 things might change? We'll see.

Actually, Raptor Lake on Intel 7 is just as efficient as as Zen 4 on N5.

TSMC/AMD need to get their act together.

There is an XTU tuning utility for Intel. I dont know what it allows you to set because I have an older system and cant use it. That said, should be simple enough to adjust the power limits in the bios. I agree with an earlier poster though, who said Intel should have made the MB manufacturers enforce the power limits and then allowed someone who wanted max performance to remove them, much like overclocking. They might have saved themselves some flack about power usage.

Really good to see competitive performance from the 13900K.

I have a 5950x and since AMD has a new platform for the 7950x I can go either Intel or AMD. I have more questions such as platform stability; performance of the 13900k with DDR4 and multi-threaded load; heat constraining performance for long workloads (e.g. a multi-threaded overnight regression test run).

I'll let all you early adopters help test this out....... I may end up skipping this generation as although a ~25% speed increase is nice; its harder to justify when you have to upgrade memory, MB and processor (my last upgrade was just a processor that gave a 20% speed increase). However, I have hope that this close competition may help prices drop!

Man, why did I get this crummy 7950X? The 13900K looks great.
Pretty much a wash, intel part has a hair faster performance in ST and gaming (+5%), and a hair slower in MT (-4%). Caveat: intel part uses 100W+ more in MT workloads for comparable performance

Expreview summary chart shows this well:

So Intel 13900k is now the budget option vs the 7950k?
Pretty much, although it sounds funny. It's a good alternative for Z690 owners who need more MT performance. As for gaming, anyone on Alder Lake has already tuned their chip with manual OC so the gains there would be more or less trivial.

Wow, the AT review is pretty bad. Multiple times where the graph results aren't quite lining up with the narration, and I'm pretty sure the the labels of 5xxx and 7xxx Ryzen parts were swapped in a bunch of the gaming graphs.

I have a different opinion. I thought it was quite good. There isn't a lot of "meat" in this release, not much to speak of architecturally. I would have liked to see some tests that would have isolated what benefits Intel is getting from the additional 8 E cores, which is easy to do since all you have to do is turn off 2 clusters in the BIOS.

That video review on page 118 of this thread was excellent I must admit.

That's 1440p, the 1080p average has a slightly higher spread in favor of the 13900K.

At any rate, I think you're jumping the gun a bit for several reasons:

1) It appears that even the RTX 4090 is still GPU bottlenecking Raptor Lake at 1080p at the settings used by HWU.

2) Games vary a lot in terms of how CPU or GPU intensive they are. If you analyze the results on a game by game basis and look particularly at the CPU intensive titles, Raptor Lake is significantly faster than the competition; particularly in 1% lows.

That shows me that Raptor Lake is just a more potent gaming CPU than the competition, and will be for a better partner for the next generation of GPUs.

Here are my impressions of the 7950X vs 13900K at this point in time. Honestly not much has changed in my mind over the hours since the reviews went live.

1. Performance-wise they are neck-and-neck depending on the application.
2. For highly multithreaded tasks like distributed computing and the like the 7950X is much more efficient. If you are going to be hammering all cores for long periods of time go Zen 4.
3. For less threaded tasks performance and efficiency are pretty equal with Raptor even being slightly more efficient as per the video review on page 118 of this forum.
4. At 90W even for highly multithreaded tasks efficiency is about the same, as is performance. But once you get above 100 or so watts it goes strongly in Zen 4's favor as per #2.
5. Raptor is end of life for mobo, Zen 4 is beginning.
6. Raptor is slightly cheaper up and down the stack currently.

I will most likely pop in a 13900K since the clocks are a big upgrade from my 12700K. I'll probably keep the power limit at the same 170W I have now. I don't NEED to upgrade but hey, we're enthusiasts it's what we do and I ain't as cheap as I used to be!

I'd really appreciate it if someone with a 12900K could run our Handbrake benchmark? Or someone with a 13900K could run it with 8E's activated.

With 13900K you are getting better silicone. For gaming I would set my CPU with max multiplier 60x best P cores / 59 or 58x other P cores, limit power draw to the level manageable by my cooling solution, as 200W. That way you would get much higher gaming performance than what you could ever get out of 13600K.

I know we've been hammering you with benchmark requests but could you run CB23 MT unlimited power in 8+8 configuration? Could you also run out Handbrake bench in that config? I'm really curious to see what those extra E's are doing?!

I have been running the CPU for a while with two cores at 6 GHz and the rest at 5.8. I observed, that while playing 4K youtube video, power draw is 30W. I disabled 2 P cores and 8 E cores, and put P cores at max. 5.5 GHz, simulating overclocked 13600K. But still, it drew 20-25W playing the video. I expected way less. Frankly I do not get it.

BTW I tried again 6.2 GHz CNB 1T run, but I got just 2395, which is worse than the result before, so I did not even screenshot it.

I may try the benchmark with in 8+8 config, but today I am heading to bed now.

No temperature tests in the review either!

20 game lineup from this channel. 13900K slaughters the 7900x:

So many things wrong there. I did not see anything about settings, wattage. I did not see a 7700x or a 7600x which quite often are faster at gaming. For the blender test, the 13900k (the top dog) goes against the 7900x which is 4 fast cores short or the equal, the 7950x. This review is so slanted, I discount it entirely.
