i7 5820k

[Ahoy Hoy]

My computer is now 5 years old and is rocking a i7 5820k whats that like performance wise to modern processors?

 

Its main use these days are now just gaming and generic computer work it very rarely does anything work related and when it does I dont have time constraints so it doing something 20% slower doesnt bother me.

 

Im thinking over possibly upgrading the graphics to a modern card 2070, 2080. 

Is the older processor going to be a bottle neck or hold back performance?

Overclock it. They generally go up to 4.5GHz without much convincing, locked clock without any dips at any point. In the end, you still have 12 threads and high clock, making it perfectly fit for even demanding tasks. When overclocked, it's probably as fast as new Ryzen 3600X which has slightly lower clocks but higher IPC. And same number of cores and threads.

 

I have GTX 1080Ti hooked on 5820K and it's so fast I can throw anything I want at it and it runs it butter smooth. I do game at 1080p, but slow CPU would show even more here, but I don't think it's a problem at all. Given RTX 2080is around GTX 1080Ti range, I'd say go for it. Should work fine.

It should should be fine for gaming.

Thanks really helpful.

 

I bet the power draw is a lot at 4.5GHz

If we look at youtube benchmarks, when OC to 4.5GHz it's almost the same as a Ryzen 5 2600/2600X, not close to the R5 3600X. If you do not belive me, search on youtuve i7 5820k vs R5 2600 and you'll be a le to see a lot of comparition videos.

 

Neverthe less, it's still a good CPU for gaming if you overclock it. Do what he says, push it as far as you can (4,2-4,5GHz) and you should have no bottleneck problem if you pair it with something like a RTX 2070.

 

Your processor still have what it takes.

 

Good luck, mate!

Depends on voltage. Mine basically runs at 4.5GHz using only 1.175V. I don't know what the consumption is, but given the voltages, it's not that astronomical. And frankly I don't care lol for as long as it gives me performance that I need.

 

@RodrigoRS

As far as I remember all Youtube benchmarks run 5820K stock and not at all core 4.5GHz. Also, 3600X pretty much never runs at max boost clocks. That IPC gap is covered by additional 400-500MHz on 5820K. There is no way 5820K in overclocked state is only as fast as stock Ryzen 2600X... It just doesn't compute.

There it's at 4.5GHz. Almost the same performance than the R5 2600(x).

 

It's still an awesome processor, matching a only 1 y/o cpu. If anyone have it, you can keep it for at least 4 or 5 years without any problem.

I know. I was thinking of getting 3900X and then realized investment doesn't make sense. Ryzen 3000 are awesome products if you have really old crappy CPU or buying first computer, but if you have an older high end, at least for gaming and casual use, it's just not worth it.

Yes. Sometimes it's good to expend a few more bucks in a good high end cpu to make it last 7 or 8 years. If you buy something mid tier, you'll have to upgrade in a few years. I7 5820k was one of the best cpus to buy back when it was released.

Before 5820K I had Core i7 920. Clocked to 4GHz. It was one of first 4c/8t CPU's and it lastd me like 5-6 years as well. I could probably stretch it for a year or two more, but the system had some other issues so I sold it. It was i7 920 at 4GHz, triple channel 18GB RAM and Radeon HD7950. It was pretty damn high end back then.

 

Though these days, mainstream platform is so good there is no need for HEDT. At least on AMD's side. My next build won't be Intel's HEDT or AMD's Threadripper. It'll be good ol' mainstream. But highest end one for sure. It's always smart to invest some more into a platform as you'll not upgrade it until it's obsolete entirely. With graphic cards, it's better to be smart when it comes to expenses as they get obsolete much faster. I usually flip 3-4 graphic cards on one same platform.
