x58 xeon vs z97 i7

I have a x5650 clocked at 4ghz, and was wondering how much faster a i7 4790k would be in comparison considering the heavy overclock have on the chip from its base 2.67ghz.

I mostly do gaming, but id like to still keep the capacity to do some editing and streaming work later on in the future.

So maybe I should go for the 5820k to keep the single core power and multithread performance?

In traditional workloads, 5820K at stock isn't that much faster than X5650 at 4.0 Ghz. ~15% difference in ST. But of course, if you OC 5820K it will pull ahead considerably.

I'd just stay with your 5650 for now. It's more than fast enough for now. With new sockets and chipsets, not to mention DDR4 rolling out this year it isn't the best time to upgrade. Upgrade at the start of a new socket cycle, not at the end.

Exactly. I've got a x5660 @4.2 and I won't be upgrading till at least Skylake-E.
I'm not a heavy gamer anyway. When I do go ahead and upgrade I'd like another 6 core or 8 core chip.

Oh is that why the 4790k and other products in that same socket line are being sold real cheap now? because in all honesty my motherboard went out and a guy is offering me a x58 board so its either take that or pay the money forward to get a 4790k or 5820k. :/

Sec, mispost

whats skylake e?

It's the enthusiast version of skylake that will hopefully have 6 & 8 core chips. The initial skylake release will probably only have 4 core chips. Regardless, i'm not really worried about it at this point, this xeon cpu I have now is plenty fast. It would be nice to have an updated chipset though.

If my motherboard went out I'd probably sell my chip and ram and just go to X99 platform. That's what I would do personally. What kind of board is he trying to sell you? Is it used?

he has pics of them on the xeon overclcokers thread and theyre like brand new looking, might be refurbs.

That might be a good way to go. Just depends on what you want to do and how much money you have to spend right now. It's going to be a lot more money to switch to X99 though. Like I said if it was me, and my motherboard died i'd probably just dump everything and go 5820k.

Honestly you can get a 4790k with z97 motherboard for like $300 from microcenter deals, sell your x5650 and this upgrade with cost you $240. That's much better than buying a used x58 board for $140.

Don't forget to add in new ram. His 1.65 volt ddr3 I don't think will work with Haswell. You need 1.5v. Unless you can downclock the voltage and make it be stable but i'm not sure about any of that...

The 4790k isn't Haswell, it's Devil's Canyon, and Devil's Canyon requires 1.35v RAM. He'd have no choice but to get new RAM.
 
What the heck is going on here.

First off Haswell is Devil's Canyon, they are exactly the same silicon. They only differ in clock speeds, and with the IHS adhesive being superior in Devil's Canyon, along with a few extra capacitors on the CPU, which enable it to clock higher on average.

Haswell and Devil's Canyon can both use whatever voltage RAM you want. 1.5, 1.6, 1.65, no problem.

cheapest 4790k deal would be like 360 bucks after tax actually which would be 310 if i sold the x5650, so even buying his board im saving 170 bucks, for me it just works out better money wise, especially having a 4 month old to take care of and my gf not working.

I didn't realize that. So haswell 4770k takes 1.5v and Devils Canyon 4790k takes 1.35v. Thanks for clarifying.

Correct.

Incorrect. If they were the same, why would Intel call them two different names? Exactly, they wouldn't.

Someone obviously knows nothing whatsoever about Devil's Canyon...

But then you have warranty on everything. A second hand x58 can go poof easily and you've just thrown away good money. Second hand gear can be great, but it has to be absolute bargain to be worth it. $140 for a 5 year old board isn't.
 
Heh. those boards are rare.. Specifically designed for Hexcore overclocking with 2 oz of copper, 16 phase power & a Hybrid Silent Pipe cooler.. Supports up to 18 drives, 3 way Sli or Crossfire, 2X Gigabit Ethernet LAN with Teaming & has USB 3 & Sata3.. @ $140 will carry Op to Skylake

"The best CPU VRM Power design for extreme 6 core CPU overclocking
Ultra Durable 3 Technology with copper cooled quality for lower working temperature
Supports newest NEC SuperSpeed USB 3.0 with superfast transfer rates of up to 5 Gbps"

Devil's Canyon is exactly the same silicon as Haswell - it is Haswell, simply on a different package (the green PCB around the IHS). They perform identically at the same frequency in benchmarks.

I've personally built several 4790k systems, using a wide variety of different memory kits that ran at different volages. They all performed perfectly fine and still do to this day.

There are countless other users also running 1.6v memory on the 4790k - get a clue before you post dude.

Sorry myocardia, you've got it totally wrong, I have to chime in with Dave2150 here.

DC 4790K = 4770K with changed TIM/IHS, silicon exactly the same.

I use a 4790K with 4 Crucial 1600MHz low voltage sticks that are rated via XMP as either 1.35V or 1.5V, which can both be set. I personally overclock them to 1866MHz using 1.65V. So you see, I could go with all three voltages on the Z97 platform and choose usage by going the low power way (1.35V) or the high performance route (1.65V).
