Perhaps ARL-R will fix a lot with 300-400mhz higher clocks. I also don’t think Zen 5 is going to bring some crazy 1T perf increase.
Even a ~20% increase in ST perf, which shouldn't be crazy at all, would bring parity between Zen 5 and ARL. I struggle to see how a small percentage increase in clocks could help overcome the likely 10-20% increase in ST performance Zen 6 is likely going to bring. Not to mention the
-X3D skus in gaming.

You’re more optimistic than I am.

Official spicy predictions:

ARL-S - 5.1ghz boost clocks, +5-7% 1T
Zen 5 - 5.2ghz boost clocks, +8-10% 1T

I think they both get similar IPC boosts. Their competitiveness against each other remains the same that it is now. After reading through the ChipsAndCheese write up and looking at what’s happened with successive cores post Apple’s Firestorm I’m fairly convinced this is what we’re going to get.

Considering 13900K is behind even the 7900X3D, what kind of rabbit is Intel gonna pull out of their hat to manage 23% higher performance in Star Citizen?



Either Intel chose a particular area that is very friendly to their RPL arch or they gonna get Bethesda to release an optimized update.

we already have a very early LNL sample clocking at 4GHz and that's a 17W part. I doubt we will get this much of a clock regression with ARL-S.

Honestly, I wonder if PTL is going to be the arch that introduces 3D stacked (or foveros base tile) cache. Intel claims Foveros Direct would be ready in 2024, so it wouldn't be too surprising to see it being used in client parts a year later. Intel has already done L4 caches in mobile parts before, and LNL already appears to have a SLC cache, so seeing something similar in PTL wouldn't be too surprising. Also, considering that PTL doesn't look to be bringing a new CPU core arch, it wouldn't be surprising to see changes in packaging/node use/ or maybe the GPU tile as well.

Regardless though, RPL is like within 5-10% on average of Zen 4X3D in gaming. Assuming Zen 5 and ARL are similar in ST perf, it wouldn't be a wild claim to suggest that Zen 5 X3D would be 10-15% faster than ARL in gaming

20A is for mobile and client is N3
Even MLID mentioned that the CPU tiles of ARL, LNL & ARL+ are gonna be on TSMC N3B. It sounds a bit unlikely though. But whats surprising is that many have overlooked a very important point that Pat mentioned a few years back when MTL's CPU tile was under development.

He said the CPU tiles starting from Redwood Cove will be Node Agnostic. Probably under Jim Keller's supervision. Meaning, all future Intel client CPU tiles will not be dependent upon nodes, pdks, cell libraries or any specific design rules.

For example, if Intel can't do ARL 8+16 on 20A, they can very well move it to N3 will very minimal effort or vice versa. Or if N3 doesn't cut it, they can switch to N4. Just saying.

LOL @ Star Citizen benchmarks. Also apparently it was Starfield where Intel is already faster because Bethesda.

Even MLID mentioned that the CPU tiles of ARL, LNL & ARL+ are gonna be on TSMC N3B.

But wait, what if Intel isn't taking any N3B wafers as initially planned?

I think ARL is getting some ADM cache variants to compete with X3D.
One would hope so, but I highly, highly doubt it. I doubt they make a major change like that when they are already making massive core changes.
LNL appears the next big step in packaging (better foveros, though not foveros direct IIRC). There were rumors that PTL might "steal" the tile design of LNL- with SOC and CPU tile combined, and I fully expect the same foveros (or better) to be used there. Now that I think about it, maybe we won't see foveros direct in client till NVL...

Uh, you do understand that even on Meteor Lake, TSMC is used for graphics, etc, right? Meteor Lake is not dual sourced, yet it is listed right there next to arrow lake. This slide (and variants of it) keep getting brought up, but I strongly suspect you folks are taking it out of context.

However, I am done having this argument. I have said my piece. We will see how things play out.


It refers to the compute tile, because of this there is no TSMC N6 and N5.

Yes, these 14900K claims are kind of ridiculous when we know it's really a 13900KS, which has been out for nearly a year. Nothing new here with the 14900K.

If Intel wanted to impress us they would "leak" a slide showing 14900K vs 13900KS. But of course then they would reveal they are releasing the same generation of CPU's.... again.

Looks more like a purposeful leak from the marketing division. Technically speaking, RPL-R shouldn't even exist in this day and age. A monolithic power hungry die on an ageing node.

But the slide does convey what they exactly want it to convey. That 14900K is a tad better than 7900X3D in gaming performance. And i think it's actually true.

We already have the 13900KS gaming performance:


14900K could theoretically support higher clocked DDR5 and that's all.

Without a serious performance per watt improvement it isn't going to move the needle for the DIY community. A margin of error percentage level of gaming advantage isn't going to do anything for sales to our crowd either. Of course there is the point that unless things change, it is really no big deal how 14th gen desktop performs. The desktop market is in a historic slump. OEMs love the new shiny to help sell their stuff, so that's its best chance to have any impact.

It’s not a 13900KS. It’s a 13900K with +200mhz clocks at iso power.

I’m not claiming it’s an exciting product or will have crazy performance but it will outperform the 13900KS in every metric.

While you’re gaming this would be the clocks of the competing SKUs.

13900K - 5.5ghz P-cores, 4.3ghz E-cores
13900KS - 5.6ghz P-cores, 4.3ghz E-cores
14900K - 5.7ghz P-cores, 4.4ghz E-cores

In some instances, while gaming the 13900KS would clock at only 5.5ghz depending on your cooling. For highly multi threaded games it will likely outperform the 13900KS by 3-5%.

You can use different games to skew results in either way. 3Dcenter meta review puts the AMD at like <3% faster than Intel's flagship IIRC. If AMD fans want to parade that around as a win, they can lol

Don't think most people care about that tbh, esp if prices are alright. Though that's my "US-based" perspective, I think electricity elsewhere is way more expensive

yea, not to mention that if one is gaming with a high end rig they are probably using a 300 to 400 watt gpu. I dont see the expense of the additional power usage as a big deal, except is places with unusually high electricity costs. The bigger problem is cooling it and the need for a beefy power supply and motherboard.

Gamers generally prefer the top-end SKUs. Or the best they can afford. Power consumption isn't usually the priority. It's all about bragging rights. Measuring contest it usually is.

True. And the leaked Intel's roadmap doesn't feel very inspiring either. 😢

MLID has claimed that ARL has LNC P-cores. If its true and LNC and 20A delivers, then we may have a level playing field. Just too many variables.

That probably the reason they still have RPL refresh-refresh in 2025 just as a safety measure.
