What's the difference between socket 1151 and 2066?

[Vibora]

Are there any differences in performance or anything significant? 

Because I noticed 2066 mobos cost a lot but 1151 mobos cost not that much.

The only difference for the sockets themselves is the pin count: socket 1151 has 1151 pins, and socket 2066 has 2066 pins. There is no difference between their performances, they're only aimed at different tiers of processors to provide the necessary support for them to function.

The reason why 2066 socket motherboards (X299) are more expensive is because they're within the prosumer platform, aimed to go with much more expensive high end CPUs, as well as including more unusual features.

...aaand the fact that they're simply overpriced.

Physical difference more pins, so you need a higher end cpu too. You most likely dont need that cpus so stick with 1151 and their cpus

[Energycore]

The 2066 is a much bigger socket and it's made for higher-end CPUs. In turn it has higher-end features and generally motherboards in the LGA 2066 are more built with bigger VRMs and more (8) RAM slots.

 

As for performance differences, you can't compare both because they can't house the same CPU.

Extra pins 915 pins on socket LGA 2066...

 

No, the LGA 2066 socket (AKA X299) is Intels' Extreme platform.

LGA 1151 is their Mainstream platform.

 

LGA 2066 Core i9-7980XE 18 cores, 36 threads, $2000 USD.

LGA 1151 Core i7-8700K, 6 cores, 12 threads, $260 USD.

pin count, feature dynamic, cpu support. Most normal users and gamers don't benefit much from going to the "enthusiast" platform. Mainly you can use higher core count cpus and, if supported by the cpu, ecc memory (doesn't matter for most things) which matters for streamers or workstations

I was gonna comment about how Intel had now released X399, then I remembered that's AMD's chipset name. Y U DO DIS AMD

Not the same, but very close - 7600K vs 7640X, and 8350K vs 7640X.

I chose to omit those because I'd rather deny that the 7740 and 7640 exist

Let's take 7640X and 7600K as an example. 

7640X is cheaper and better, why? Is it because of the mobo high cost?

The cost of the mobo offsets it, yes. 

 

But the i3-8350k exists which is the new 8th gen equivalent of both of those chips.

The i5-7640X is cheaper, but everyone, including reviewers, are still tearing Intel a new a$$hole about it.

Did you see Linus' "Ranting in the Rain" video?

Spoiler

 

And here is Gamer Nexus also saying like "WTF is this".

Spoiler

 

And you got Paul from Paul's Hardware saying "$250 CPU in $490 motherboard? Wat?"

Etc.

 

i5-7640X and i7-7740X should not exist.

 

It's a LGA 2066 chip cut down to i5-7600K and i7-7700K level, along with a BUNCH of stuff on it disabled.

 

Intel's *marketing* was the 7640X and 7740X is a "temporary place holder" CPU for people who WILL upgrade to something like the $2000 i9-7980XE.

The problem is, you need to use it on an expensive X299 motherboard, BUT, you are only limited to 16 PCI-E lanes, and only CERTAIN RAM slots work.

Also like 3/4 of the features on X299 are disabled if you use a i5-7640X or i7-7740X.

 

Get a i7-7700K...but with a $500 motherboard instead of a $150 one!! Heeey!!!

You either go with a i7-7700K or i7-8700K, or commit fully into X299.

Incorrect.  They just don't add pins for fun or to make them incompatible, they are a compromise between functionality and cost.  The LGA 1151 is cheaper because it is cheaper to make motherboards for -- and it is fine for your average gamer (where the LGA2066 would be overkill).  If you don't need it for what you do, then don't buy it - but just because it is not for you does not mean it does not serve a function.  

 

What do these extra pins on the processor/motherboard give you?

 

Potentially double the PCIe lanes (24 vs 48).  On the gamer board (1151) you will get a maximum of 24 lanes, on the LGA 2066 it will support up to 48 lanes.  The more lanes the more concurrent throughput.  After maybe a GPU (16 lanes), and a M.2 SSD (4 lanes), chipset (4 lanes I believe for the rest of the onboard functionality I believe including a 1Gbit Ethernet port) - you have to basically implement some sort of "bandwidth management" (i.e. switch) which means throttling bandwidth to your CPU.  I said potentially double since you need a reasonable processor to take advantage of it (10+ core Skylake or Xeon W).  

 

Up to triple the core count.  6 vs 18 (the next consumer socket -- not likely to be compatible with the current 1151 -- likely a max of 8 cores).

 

Double the memory bandwidth, i.e. quad channel memory vs dual channel (again more bandwidth) - which means to get the most of it you install memory in sets of 4.

 

Double the memory slots (8 vs 4).

 

Double the maximum memory allowed installed (128GB vs 64GB).  

 

If you install a Xeon CPU you can also install ECC memory.  According to a UofT study, 32GB of memory will average about one-bit error per hour.  This does not mean bad memory, just an undetectable error in what you are computing.  For gaming, something like this does not mean much, but when what you are doing is life or death type stuff or you cannot afford the chance of an error - it is better for the computer to know that something was wrong with the data.  

 

If your primary use of your computer is gaming - then lga1151 is your best bet since you are not likely to use any of the benefits of the higher pin cousin.  If you use your computer for other tasks - you have to evaluate whether the LGA2066 is a better fit.  

 

So no, just adding pins is not the answer... pins actually hook up to stuff.
