Which CPU gen (Intel) was last soldered?

I'm curious if my Ivy Bridge-E, 22nm (4930K) is soldered or not. Which generation was the last to be soldered, and did they start using cheap paste/TIM for every single generation after?

I'm really bad with CPU gens, but let me get this straight. By your definition, the:
i5 2500k & 5930K are soldered, while an i7 2600K, 4790K and my 4930K is not?

Mainstream Ivy Bridge was when they switched over to thermal paste. Ivy Bridge-E has solder underneath the heatspreader.

Sandy Bridge CPUs used solder.

Nope, 2nd generation i3s, i5s and i7s (LGA 1155) are soldered. All LGA 2011 (3820, 3930K, 3960X, 3970X, 4820K, 4930K, 4960X and Xeons) and LGA 2011-3 (5820K, 5930K, 5960X, 6800K, 6850K, 6950X and Xeons) CPUs are soldered ;)

Thank you very much to both of you. I got what I needed :)

Actually, one more question to both of you @PCGuy_5960 @Godlygamer23: Has the Paste/TIM become worse over time/generations? If you compare for example similar quad cores with same TDPs, let's say a 4790K, 6700K, and 7700K. Is there any change in quality of the paste? How come for example it is way more difficult taming a 7700K over a 6700K (temp wise)?

The TIM hasn't really changed, but Intel keeps changing the IHS design and/or their application method, so the TIM sometimes performs worse than it should (7700K)

I see. So every non-soldered CPU was actually tameable with a lower end coolers before Kaby Lake. Hmm... Interesting

@PCGuy_5960 I'm curious to see if Coffee Lake's IHS design/application method will be like Kaby Lake or the older gens. Want to sell my X79 system soon :P

Adding two more cores and a slightly better iGPU will mean Covfefe lake will have a bigger die than Krapy Lake.  I have lots of info of what CPUs where idium soldered and what ones where not. On the older platforms, like LGA 775, generally Celeron processors where never soldered. Most of the chips with small dies where not either. Intel has always used TIM on the lower end chips, and recently on all of them, much to the dismay of it's customers. 

Yours faithfully

@PCGuy_5960 Btw, delidding a soldered CPU and replacing with LM will lower temps theoretically, correct? Just that it's more risky to delid a soldered CPU?

Came across a video from der8auer delidding one of the soldered CPUs in your list above (5960X), and getting 7° degrees celsius cooler.

Also, maybe going slightly off topic here, but does any of you know if Ryzen 2 will be soldered like its little brother? Am I asking for early unknown information? :P @Lord Nicoll @PCGuy_5960 @Godlygamer23

I don't know if we have much information on Ryzen 2 yet.

All we really know is that Zen2 is a die shrink/refinement of current Zen. But it seems probable that AMD will continue soldering the IHS.

I'm one of the few people I know that tend to repair electronics with a smith's hammer on a regular basis.

given how proud and gloaty AMD is about the soldering that they do, and how intel does not, I doubt they'll use TIM, maybe on the cheapest models.

I've delidded loads of indium metal CPUs, Liquid metal isn't really that much better, it's just the gap is smaller usually as the die is held closer. Running with no IHS and liquid metal was a massive improvement but modern waterblocks aren't meant to be used without IHS's, however they themselves act as an IHS

Yours faithfully
