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 this not win 11 22h2 that's affecting amd processors?

i hate bull like this.
why cant people be honest , just have to push BS agendas

if it is "A Plague Tale: Requiem is partly very CPU limited. Even with a 7950X + DDR5-6000 the gameplay doesn't feel smooth in some spots like this one below. "
then we aren't interested in avg we are interested in stutters , ie 1% avg and the 0.2% avg. funny how those are like 20% and 15%.

But even that doesnt tell the full story because without inter frame variance ( jitter) data both can be just as crap as each other.

I was going to say it could be the dual CCD issue, but he tested it with one CCD and there wasn't any difference.

There are some sections of the game that are very CPU limited like in the town areas and when the rats are on screen, but overall, the game is mostly GPU limited.

normally I'd give people benefit of the doubt but capx is known for their intel bias. I've got no skin in the game of course, not yet anyway. the 13900K isn't a realistic investment for anyone using their computer for more than gaming imo unless you don't care about electrical rates and run a loop to keep that hot pot pie cool.

The Raptor Lake build thread has shown this not to be true. My own 13900KF is underclocked and undervolted and does 5.2ghz on the P cores and 4.3ghz on the E cores at 220w and 1.196v at max power draw. I use my rig for mostly gaming, with some encoding/transcoding on the side. Electricity is also relatively inexpensive where I live so I'm not even worried about that. But since I am gaming at 4K and air cooled, the stock power draw is unnecessary.

Sounds like a poorly-optimized game.

Or too dependent on memory bandwidth which the 13900K has more of than the 7950X.

Intel Core i9-13900K CPU Review - Page 4 of 9

The Intel Core i9-13900K CPU is here, and we put it through its paces in benchmarks and games to find out how it compares to Ryzen 7000 series.

www.thefpsreview.com

7950X is awful in these benchmarks!

AMD better release a revision of the Zen 4 silicon soon that can work with DDR5-7200.

And then the poster here, who reiterates this bias is also known for Intel bias. So bias, posting bias just makes me want to puke.

It's been the case for a long time - some reviewers finding true CPU-limited passages while others using the casual GPU-limited ones.

It's always about analyzing the bottlenecks. Intel (and AMD X3D) has nearly always done better in those horribly non-optimized places. Intel better be great at this given their committed resources (the same goes for X3D).

How is it bias just to post it? I considered buying the game myself so I watched some reviews, and many of them mentioned performance drops in the same area that CapFrameX did, namely the town and whenever the rats were on screen. Skill Up mentioned it in his review that his 3700x and 2080 Ti was in the 20s in terms of FPS at 4K in a non busy area, and he had to drop the rez down to 2K medium settings and DLSS when in the town and it still didn't get good FPS. So he ended up lowering it to 1080p with DLSS and medium settings and the FPS still wasn't satisfactory. That to me indicates a CPU bottleneck but he didn't specifically mention it. He then tested it with an RTX 4090 and a 3950x, but with FG turned on and then his FPS went through the roof! I wish he would have tested with FG turned off then I would imagine his FPS would have plummeted like a rock due to being CPU bottlenecked.

It wouldn't be hard to prove that. Just detune the RAM on an Intel system to have similar memory bandwidth to the 7950X test system (or whichever) and see if the 13900k loses fps.

There might be some truth to this. Raptor Lake's cache bandwidth is significantly better than Zen 4's, but Zen 4's cache latency is significantly better than Raptor Lake's. But since Raptor Lake has more OoO resources, it can presumably hide that latency better.

Case in point here is the 13700K Aida64. Keep in mind this benchmark scales with core count, so the 13700K and the 7700x are both 8 core CPUs and they are using the same RAM, but the Zen 4 has CR1 which should perform a bit better.

And now the 7700x:

As I said, Raptor Cove has much greater bandwidth going through the core than Zen 4, in addition to memory bandwidth.

Did not see this posted before..

So the 13700HX is a rebranded 12900HX.

I do not know how these things can be in mobile systems.

Of course it went through the roof, you were watching the 5 minute commercial included at the end of an Nvidia sponsored video.

The 13900HX will be going to Desktop Replacement Laptops.

But since I am gaming at 4K and air cooled, the stock power draw is unnecessary.

Undervolting and underclocking are modifications most users won't be doing. Out of the box performance, the 13900K will run hotter and throttle, and use more power. Limiting it to intel pl1 and pl2 limits performance. I don't know where you live and certainly don't care, but not every place in the us has low electrical rates or may have been low and now high. Our european friends are more screwed than us and thus the Ryzen makes more sense on paper. You make a good point, but why buy a 13900K if all you're gonna do is game? The cheaper 13600K makes more sense, especially as it wipes the floor with the 7600 and 7700xs. Oc that 13600k up and you've got a fantastic gaming computer.

yes, but intel imc's are generally better engineered than amd's. I can't remember how their fsb's where before. I want to say AMD had the upper hand then.

In a way I can't blame them. For us old fogies we experienced the height of amd long ago. I'm indifferent to either brand, but raphael is coming home for christmas with me. Hopefully I can take a few days off work to make the drive to various stores and pick up my components. I have the entirety of next week off but will be getting my christmas decor up. One of my neighbors has got a mini cherry picker he'll be lending me so I don't fall off the ladder again this year.

You'd be surprised. 100+ W CPUs and GPUs are pretty common in gaming laptops/DTR.

 

[Carfax83]

It's still impressive though that FG can deliver such high FPS when the graphics card is clearly limited by the CPU. The 3950x he was using was a noose around the RTX 4090's neck, as clearly seen by the footage in the open area at native 4K where the graphics card can only achieve 65 FPS at native 4K. In the village, the FPS would probably have dropped into the 30s.

Intel's intake outtake should be getting better in another generation or two with them going wider in the front and back per some rumor posted a while ago. I hope amd is taking note even though zen 5 design may be finalized at this point. I expect they're taping out at this point or close to it.

I also do encoding/transcoding.
