Intel Core i7-11700K Review: Blasting Off with Rocket Lake

On the high Inter core latency of Rocket Lake, i've put this theory out before but i think its worth saying again.

Intel may have ditched the Ring Bus with Rocket Lake and that would explain the high Intercore latency, Sky Lake-X, Intel's HEDT line had a "Mesh" core interconnect because the CPU's were just too big for the Ring Bus, it doesn't work on a CPU of that size and if you remember Sky Lake -X was also down on performance in games compared with the 9900K.

Just when AMD have thier Intel core Latency to around 17ns Intel have had to push theirs up to around 30ns and with that the IPC gain is eaten up in gaming.

I don't think Intel were expecting AMD to improve their Intercore Latency. Certainly not by this much. AMD are up over 40% in some games vs Zen 2.

Interesting that Steve said they had an 11900K and he seemed utterly unsurprised at the production benchmark results. Also interesting that he does not expect the newer BIOSes to improve performance by more than 1/2% in some specific scenarios. The final interesting point is that he said it was also essentially an 11900K review as well because a small clockspeed bump is not going to provide much performance.

As far as the cooler goes they did not think it was holding anything back and Tim also made the point that what if it takes a high end cooler to get that level of performance and a lower end cooler causes throttling.
 
After a long week of 12-16 hour days, a long Anandtech review of a new processor is the relaxation I needed.

Overall then Rocket Lake comes in as a decent, competitive offering (hurrah and well done team Blue) but a tad below my 5800X, particularly in gaming (well done the Red team!) and AMD owners can rest easy and happy in their hardware choices.

Brilliant :D

The only thing Intel eally had going for it at a push was gaming and now its got slower but Intel will be more then happy to resell the chip we was supposed to get again in 6 months time and of course you'll need a new motherboard and pay ££££ for it.

Completely pointless having 2 gens on this socket if the later gen has got worse and more expensive but the good thing is that Intel have finally put a new IGP in these higher end desktop CPU's I guess. :confused:

I cant wait for other reviews as I bet in some games some of these new chips may get smoked by a 5-7 year old 7700k lmao.
 
This is actually quite disturbing to watch and read about. Much like a lot of forum members i have been on here since the early 2000's and have been through many cpu's. AMD to start with, then to Intel with Wolfdale and Nehalem and than back to AMD with Ryzen 1.
I don't think i can ever remember a time during those 20 odd years when cpu's have actually gone backwards. But it is looking more and more like Intel are going backwards. It certainly is their own fault they are having to, but we as consumers need a minimum of 2 competitors in the market to move innovation on. That certainly isn't happening at the moment.
 
Hardware Unboxed has the new Intel CPUs and have been testing them they jut can't publish the review yet.

In the meantime they're reviewing Anandtechs review of the 11700k

Overall they seem happy with the review, which implies Anandtechs results are similar to what HU is getting. HU did also mention that a new microcode bios was coming but were told that any performance difference would be negligible (like 1%)

 
Haha.... oh Tech reviewers. Clueless, utterly clueless.

Linus went to make a dramatic punchline argument that while the 11700K appears slower; at least you can buy it, that the 5800X was unavailable, so he went to the US "retail site" to look for the 5800X and expecting to see it out of stock it was there and at MSRP with a badge on it labelling it as "The Best Seller", which made him go quiet while he absorbed that fact.

Quite a lot of these reviewers have been saying it was impossible get Zen 3 for about as long as they have been available, it just proves they don't research their own subjects before bleeting a whole load of bull crap.

Yes i found this pretty funny, live on air he just demonstrated how out of touch he is on his channels subject.

He's making yet more hair brained assumptions... Jezz Linus.

The reason the 5800X and 5600X are in stock is because AMD switched to making 80% of CPU wafer supplies to these chips, with the remaining 20% going to the 5900X and 5950X, its 1 CCD vs 2, twice the yields, easier to keep in high demand supply, clearly its working because anyone can get one right now, or tomorrow, or the day after...

"Why make the 6700XT when they already can't supply the 6800/6900 series?"

Two things Linus, can't remeber where but i read somewhere Big Navi was already AMD's highest selling, in terms of numbers, high end GPU's in many years.

That doesn't mean they would sell a lot more if they had an infinite number of them to sell, especially not at their price.

The 6700XT is half the size, that is at least twice the yields, again as with the 5800X vs the 5900X you can make twice as many, or more with the same wafer usage, you can put a lot more of them on the market if you switch production from the 6800/6900 series to the 6700 series, that way you get a lot more availability and a lot more sales.

It is what it is right now Linus, with smaller GPU's they can ease a lot of that supply issue.

Depressing actually, I was hoping for more from Intel, it's like they are polishing turds. No price war incoming that's for sure. AMD is king, they can hold their prices firm and their heads held high still, no competition.

Its a complete role reversal, tho i'm sure Intel don't want that and will pretend they still have their "Premium mindshare" the 11700K will also be £400 or more just watch, the may be in for a shock tho because IMO Intel's mindshare is all but completely wrecked at this point and Intel have no idea how bad it actually is.

I seldom watched any TechTubbers, but isn't talking before thinking very much what they are all about?
Still, kudos to him for not editing that part out!

Well AMD's Bulldozer was a regression compared their previous 'Stars' architecture when it launched.
Some of was due to just bad assumptions about the mix of INT / FPU instructions in code and other poor choices.
Rocket Lake's problem seem more about regression in latency and memory speeds. So all Intel have to do is copy what AMD did starting with Zen1, Zen1+, Zen2, and Zen3!
Alder Lake will be the really interesting one. (As in the alleged Chinese curse "may you live in interesting times".)
Can they fix the latency issues? Will the mix of cores cause major OS scheduler issues or have they already got all vendors to patch things? Ditto device driver. Plus of course as their first desktop 10nm will clocks go down? No point increasing IPC by 10% and regressing clocks by 10% for example as that's just standing still.
Of course, Rocket Lake looks more like 1 step forward, 2 steps backwards!
