How Much of a Performance Increase from i7 3770k to i7 5820k

[Net]

My current system is:

i7 3770k @ 4.5 GHz
12 GB RAM

I'm considering upgrading to:

i7 5820k
32 GB RAM

I'm wondering how much of a gain this will be and if its worth it. It'll be around $800 after I get the mobo, ram, cpu.

Should I wait for something that Intel has coming down the pipe for enthusiast?

Hard to fault the 5820K, some applications will show 50% increase.. X99 isn't going anywhere for awhile, so it's a good bet.

It depends on the workload. If you can use all the threads, as Burpo said, you could show 40 or 50% gain. For gaming, not so much. Newer games are starting to use more threads, so x99 is more attractive. However, the first preliminary benchmarks of DX12 are all over the place, so IMO it is hard to say for gaming how much increase you would see in the future. With current games, I would guess 10 to 20 percent absolute max in games. And all this is assuming you get a 5820K that will overclock to close to the 4.5ghz of your current 3770k. The chances are good that you will, but nothing is guaranteed.

To be honest, I would not upgrade for gaming, or at least wait to see what BW-E brings to the table. If you are running productivity apps that can use all the threads, that is a different story.

The 5820 has a core increase of 50% as well as a decent IPC increase over the 3770k. In some modern games I think the combined increase would be reasonably substantial so long as you have the GPU head room to let the CPU pull some extra weight. You have to match the OC of the 3770k though or the benefit drops fast for gaming and basic tasks.
Heavy threaded stuff, yeah of course it will be faster. Its 50% more CPU.

I've been contemplating the same upgrade for the simple sake of boredom, but ultimately, nothing I do is really CPU limited. I do the occasional 4k video edit which could see some benefit, but it's just that, occasional. I game at 1440p running a 980Ti and I'm easily GPU limited in just about every game, with the exception of something like Counter Strike, but that thing is running at well over 200 frames anyway. If your goal is better gaming performance, a new, or a 2nd GPU is likely going to be far more beneficial.

It really depends on what you're doing. 5820K is only a 1-generation newer architecture, so if you don't overclock quite as high, in applications that can't saturate all of the cores, you'll break even or even have a performance regression.

If you do a lot of heavily threaded stuff (e.g. scientific computing, encoding) you'll see a worthwhile improvement. If you're using it for light desktop tasks and gaming, I doubt you'll be able to tell the two apart.

I'm thinking about doing the same thing, but from a 2500k to the Broadwell-E equivalent of the 5820k. My dilemma is whether it makes more sense to go with Kaby Lake instead of Broadwell-E. Isn't X99 (the HEDT chipset) getting a little long in the tooth....

 

[Yuriman]

A decade ago, a year and a half would've been old for any electrics, but I'd argue it isn't, as the die shrink CPUs haven't even been released yet for it.

Anandbench comparison.

Looks like with overclocking, it will be a large boost for many things.

But, new chips are on the way...

 

[Magic Carpet]

I'd wait for Broadwell-E. 5820Ks might become even cheaper.

I took the leap from a 2500k @ 4.6GHz to a 5820k @ 4.4GHz and haven't looked back. I had a rebate from my credit union for TigerDirect, so I got $60 off. It came out to about $320.

Just the added features of the new chipset has been awesome. m.2 with PCI-E 3.0 x4 for a Samsung 950 Pro has been great. With gaming, I have seen some improvements, like in the Witcher 3 and GTA V, but nothing amazing. It's been when multitasking or rendering stuff where it has been an outstanding buy. Love the options it gives over an i5.

 

[frozentundra123456]

Yes, your upgrade seems about the minimum that makes sense. The op otoh has a newer i7, so he has hyperthreading and slightly better ipc, so the upgrade is quite a bit smaller

In crappy DX9 era games your performance will be the same.

In DX11 AAA games your performance should go up, specially on minimum fps area.

In DX12 games this can be even higher, expect at least more thread utilization across all 12 threads on the 5820K

In productivity software the gain can be from as low as 60% to as high as 90-95%. In Vray renderer, a 4770K performed about the same as a 4930K with 2 more cores. Now add 2 cores worth of performance to the 4770K and take 300mhz for it's multithreaded boost clock. The performance gain can be that high for parallelizable workloads because Haswell was a dang good Tock for those scenarios.

Broadway all the way!

I went from a 2600k @ 4.5ghz to a 5930k @ 4.5ghz and I feel it was worth it. I game on a pair of 290x's and everything feels considerably smoother. I haven't really benched the 2600k since 2011 in anything other than some synthetic CPU tests (Cinebench, etc which obviously saw huge increases) but just the overall feeling of everything is better.

5930k also has way more PCIe bandwidth than your 2600k- each GPU goes from 8X PCIe2 to 16X PCIe3. That's 4X the bandwidth! You will get much less stuttering from things like texture uploads and synchronising between GPUs (since Hawaii does Crossfire over the PCIe bus, without a bridge).

 

[blotto]

Yeah, that's specifically why I went 5930k over the 5820k. In general most say that 16x8 or 8x8 isn't that much different than 16x16 but I felt that if I'm going to continue on with multi-gpu setups I may as well do it properly. What doesn't bottleneck in 2015 may in 2020 and based off the lifespan of my 2600k it may be that long for another upgrade.

 

[Headfoot]

I went with 5820k over 5930k, because by the time the 2nd 8x PCIe 3.0 slot is out of date, Broadwell E drop in replacement CPUs will be available and no longer new.

how do you have 12 gigs of ram?

three 4 GB sticks. The 4th memory controller is broken on this memory board unfortunately, I have the fourth 4 GB stick from my last build just lying here.

Achieving a high overclock in the 5820k like I have with my 3770k is a concern that I had before posting this. And it's still something that is holding me back from pulling the trigger. Reason being that if I spend the money and its not a huge change then I'll be very disappointed.

The limitation on my system is memory and I'm doing multiple VMs for developing in Hadoop. The development is just for learning on the side though so I can keep the VMs low. I'm going to hold off to see what it feels like to have those VMs running around 1-2 GB each.

I'm really surprised that this system that I built back in 2013 is still very fast. I'm on windows 7 and it runs great. It's a mixed feeling though because while that is awesome I'd like to experience a huge performance increase like the old days.

Thanks everyone for the comments. Please continue commenting. It's not ruled out that I won't upgrade in the future. I still need to see what it will be like with my VMs.

I went from a 3570K to a 5820K. If I had a 3770K, I've probably wouldn't have upgraded...
