Raptor Lake Leaks + Intel 4 developments

The maximum safe voltage for 14 nm at 1t workloads was around 1.65v. That was also the stock TVB voltage applied on a 10900k. From what I've gathered, its not far off for 10nm either. A 12900k already does 5.7 ghz below 1.6v kinda easily, so 6ghz on 1c isn't out of the question. But all cores at 5.5? Dont think its gonna happen.

Not 12900k, but seen another 13700k

This 13700k is set to 5.6ghz on P core and 4.5ghz on E core with 1.4v, power draw is 280w, temperature 83c on cores and 97c on package using 360mm AIO

 
The 12900KS can do 5.4ghz on stock voltage apparently, so I think they've got their work cut out to show improvements vs the 12th gen.

Probably why the 13700k has more cores than 12700k and so forth across the stack

But also, after looking at the oc3d review, it seems a 5.4ghz 12900ks pulls over 300w under load and it throttles on AIO cooling at 100c, which is a bit different to a 5.6ghz 13700k which is pulling 280w and not throttling despite these two chips having the same number of P and E cores.

Kinda looks like Raptor lake is better than a binned alder lake, lower temps, lower power draw and faster clocks

You have a point there, more cache and around 200mhz higher clocks (approx. 3.7% increase). I think 97 Celsius for the CPU package would limit the 13700K to high end water cooling only, at this clockspeed? At least, to avoid thermal throttling. Maybe worth running it at stock speeds, especially with air cooling (same will also be true for the 13900K).

I think the total L3 cache amount is the same (30MB) for the 13700K and 12900K /KS. But the L2 cache has been increased from 1.25MB per core, to 2MB per core.

It's a good CPU in the sense that the spec appears to be superior to the 12900KS.

It seems like the 900s in each series always have extreme cooling requirements, probably the same for the 13900K.

Looking at the cooling requirements, it does seem as though lots of people (e.g those using air coolers) might as well just buy a 13700 or 13900 (rather than the unlocked variants), as the all core speeds should still be 5.0ghz or higher.

I don't know man, im very sceptical. 280w in what? CPU Z maybe...but in a CBR23 impossible. It will need like 350w.

Just to clarify, when im saying possible / impossible, im referring to normal methods of cooling, like a good aircooler or aio. Going custom loop with radiators on the balcony isn't what id call normal.

Depends on the workloads you're running but those who just game could probably just stick a hyper evo 212 on it and be fine.

its a light workload. Also just blasting vcore and high llc. Look at vcore min. That’s some flat llc action.

some of our guys will have chips next week locally. We will see what they offer when voltage tuned running Y-Cruncher

Cpu z? Yeah i know, thats my point. In cpuz i can do 5.5 all core on a u12a on 12900k. But cbr23 it throttles to 5.1 or 5.2

Well the hyper evo 212 struggled with my 10700KF, reaching the thermal limits in Prime95. It's not really fit to be used for many modern 8 core CPUs, in my opinion. Might've just needed new thermal paste though?

Works perfectly fine installed in my brother's PC, which has a 6 core i5 8400.

Seems that the 13900 part(s) die size is a whopping 49mm2 bigger than the 12900 parts(s) or (23%) 257mm2 vs 209mm2, that's pretty big. Might explain some of the 280w+ shots on the 13700's if it has a similar increase, although who knows if they are the same design or a different part, I suppose the could be binned and lasered to make them 13700's.

Yields will be interesting, but 10nm seems to be mature now , doesn't say much for the extra wafer cost per die, so the rumors of them increasing the prices could turn out to be true.
 
i9s always the idgaf edition, taking the chips to the maximum the silicon can handle (within thermal limits), regardless of efficiency. Tbf, at least the 10th gen i9s had 2 extra cores.

That would be because the evo 212 is a cooler that's rated for 150w of cooling capacity and the 10700k/kf has a PL2 power limit of 220w. So of course a 10700k is going to get very toasty unless you undervolt it or lower its power limits
 
Well, the most power I've seen it consume was 140-145w in Prime95, so the EVO 212 was pretty marginal (it was enough for gaming though). This was with the clocks at 4.6ghz. With a better motherboard though, I'm sure it would draw more power than that.

No matter now though, you can get decent air coolers now for around £50, that work on AM4/AM5 and LGA1700. Probably only need something higher end if you buy a 12900K or 13900K.
