Question Best LGA 1151 CPU?

I think about upgrading my motherboard and it has a LGA 1551 socket installed. I wanted to know between all the favors of Intel and AMD, which is the best based on of price and performance.

I was going to get the Kaby Lake but the I saw the Cross Lake? which never heard of. Know nothing about AMDs.

There are two 1151 sockets, which are physically identical but electrically different. One for Skylake and Kaby Lake CPUs and one for Coffee Lake CPUs, which is often called LGA 1151 v2.
Fastest CPU for the old 1151 socket is the Intel® Core™ i7-7700K, very closely followed by the Xeon E3-1285 v6.
As you can't get higher than 4 cores on the old 1151 socket I don't know if a CPU upgrade alone is worth it.

Whats the budget ? Very likely a hex core AMD is the way to go. Like a 3600 or 3600x.

What am I missing here?? First the OP posts about the best LGA 1151 cpu then proceeds to ask about a motherboard upgrade and then to top it off the OP says they were thinking about going with a Kaby Lake cpu but mentions maybe going with an AMD series cpu.....wtf....

Look OP your 1151 socket mainboard doesn't work with AMD cpu's. If you do in fact have a 1151 mainboard and want to upgrade the cpu go with the i7-7700K.

Used 7700K's are upwards of $200. Wouldn't be worth it.

Well I guess I just assumed the OP wanted the best because they said BEST in the title. If you have an alternative to suggest I'm sure they would appreciate your input.

He wants an M.2. 1151 does not have that as far as I know. He said he doesn't know anything about AMD but is open to it. My $208 suggestion was to give him motherboard with M.2/cpu, 6 cores and within his budget. 7700 is only better in gaming. I have not heard from him what his use case is.

But the OP is asking for the best 1151 cpu......that is literally the title of this thread. Why are you recommending an AMD cpu and mainboard???
And FWIW my Z170 1151 mainboard does in fact have a bootable M.2 slot.

From the very first post :
"I wanted to know between all the favors of Intel and AMD, which is the best based on of price and performance."

And I told him my opinion, based on his budget.

The M.2 slot become common beginning with LGA1151 motherboards (e.g. Z170 chipset).

Some manufacturers added M.2 slots on later revisions of LGA1155 motherboard (e.g. Z97 chipset), although they weren't full speed. My son's "old" motherboard had a M.2 slot, the Asus Z97-A/USB 3.1

But do they want to upgrade their cpu or the whole system?????? This whole thread is confusing as frak.....

Well, he said he did not have one (at least thats the way I read it) and I actually have a 1151 socket motherboard and CPU, and its not there. So I thought it was not on them, but thanks for the clarification.

Hard to say since so much info/details have been left out here.

Maybe they have a bare-bones motherboard. However, if they want a new motherboard, CPU, and a NVMe SSD with only a $200 budget, I don't think it will happen unless they buy used components, and get a really great deal.

Honestly, it sounds like they may want to have their OS on SSD (maybe they already do), and save up until they have a larger upgrade budget. Most users don't take advantage of the extra bandwidth of a NVMe drive, and based on their question here, it doesn't appear that they would be one who does.

Are you kidding me....I said all of this already. This thread is so fraked.......

Hey OP go get yourself a shiny new AMD cpu and all the components that go with it. Get back to us if it's out of your $200 budget.

That for all you help but I had a change of heart and am looking at the current Comet Lake as possible upgrade meaning buying a brand new PC!

Comet lake is decent, but depending on your schedule you might want to wait. Zen 3 will be announced October 10th which has high potential to be the best all-around desktop CPU. Even if that doesn't interest you it should put some pressure on Intel's pricing. Also Rocket Lake should have Sunny Cove cores (significant IPC uplift) and PCIe 4.0 (and m.2 that is on top of PCIe 4) and launch some time next year.

Comet Lake is currently the least forward looking platform (with some motherboards maybe supporting PCI 4.0 but no guarantee).

I was just perusing this earlier tonight.

Newegg has ASRock B460M Steel Legend micro-ATX board with 2x PCI-E 3.0 x4 NVMe slots for $89.99 until noon tomorrow, and the Intel i3-10100 (4C/8T, 3.6Ghz base, 4.3Ghz Turbo) for $119.99. Combine those, they are new fresh kit, that almost fits into your budget.

Then you can get a budget 1TB NVMe SSD for $95-110. Newegg's e-mail flyer has or had the Intel 665p 1TB NVMe PCI-E 3.0 x4 SSD for $94.99 after a promo code.

These end soon, so check them out!

The AMD option, is a Gigabyte B550 Aorus Elite ATX AM4 board for $144.99 (currently $15 off list), and a Ryzen R3 3100 for $114.99 ($15 off list, but MSRP is supposedly $99...). That would give you the option of a PCI-E 4.0 x4 NVMe SSD, which can be up to 7000MB/sec read speed. (Check out the Sabrent Rocket Plus 4, I believe it's called.)

Edit: The Intel is cheaper, to start with, but doesn't offer built-in overclocking of CPU and RAM support, nor will it support PCI-E 4.0. The AMD solution is slightly more capable, and more expandable, but more expensive.

There are some budget B550 micro-ATX mobos for ~$110, but those lack the 2.5GbE-T ports, that both my Intel and AMD mobo picks have, for future-proofed internet and LAN for the next few years.

They never bothered to come back and clear up anything here, but they created another thread here: https://forums.anandtech.com/threads/intel’s-future-cpus-rocket-lake-and-alder-lake.2585033/

It appears they are going to go with a Intel 'Rocket Lake' CPU because it sounds "fast". ;)
