Helping choose between 5820K and 5930K

[wiseguyin]

Hi,
I am noobie member and building my first PC. I know I want one of 5820K or 5930K but not sure which one is cost effective for my situation. The new PC will be mostly for some rendering, occasioinal gaming and running some virtual machines. I know I will have one GTX 970 + 1 firepro W5000 in it.

Will the 28 PCIe lanes of 5820K be a problem?

TIA

The Xeon E5-2620 V3 and Xeon E5-2630 V3 are also plausible options.

Xeon E5-2620 V3 is about the same price as the 5820k, but it has 40 PCIe lanes and runs at 2.4 GHz.

Xeon E5-2630 V3 is $50 more than the 5930k, but it has 8 cores and runs at 2.4 GHz.

Thanks - I am still doing some research (though some components are bought already). I have some flexibility in time. I will have to check the two options you mentioned.

You have to decide whats more important to you. everyday use and gaming or rendering.

Everyday use and gaming still greatly profit form high frequency and hence the fastest consumer quad core will give you the best results. Also depends on the game. Xeons can't be OCed so compare that xeon vs a 2.4 ghz base frequency vs a skylake 6700k with 4 ghz base. Consumer quad-core is an easy win for everyday use and gaming.

Of course the additional cores will greatly help with rendering. I would avoid xeons as you can OC the 5820/5930k and also get good single-threaded performance.

rendering? 5930k.
6 cores that will easily top 4Ghz, sorry but the xeons can't compare.

5820K no doubt. Only reason to go with 5930K is if you have 3 or more videocards, or run a lot of PCIe storage.

You are saying that as if everyone overclocked.

The Xeon E5 16xxV3 line is directly comparable to the Core i7 Haswell-E line, they're high Frequency and also extremely similar in cost, you're mostly getting Registered+ECC Memory support in exchange for overclocking.
Models to consider are Xeon E5-1620V3 (4 Core, 40 Lanes, but 100 U$D cheaper than the Ci7 5820K), 1650V3 (Nearly identical to the Ci7 5930K. It can't be overclocked but has ECC Memory support. Better purchase if you don't overclock as it has more features as should be around the same price), and the Ci7 5820K itself (Cheapest 6 Core, but the only LGA 2011-3 Processor that does NOT have all 40 PCIe Lanes. Stupid Intel figuring out a way to do market segmentation since no one would pay the price premium of the Ci7 5930K for just a few mere stock MHzs, so they instead crippled the PCIe Controller).

Word! I MIGHT OC to try it but my CPUs are at stock 24/7. I put upgraded my wife to a 5820k from a 3770k and like others say, unless you're going with a bunch of high end video cards and an M.2 SSD, you're not going to need the extra pcie lanes. Her machine is sporting a single 980, 750 Ti for physx and runs everything perfect.

Take a look at the benches. They're nearly identical so you're not losing anything by going with one over the other. http://anandtech.com/bench/product/1320?vs=1316

well - as i mentioned, i see a maximum of 2 cards being used. Problem is one is a firepro and the other a gtx 970.
so i am trying to make sure i dont run out of lanes. i think i might be able to x16 for firepro (primary) and x8 for gtx970.
leaving 4 lanes (assuming i go with 5820k)

That should work. right?

 

[MrTeal]

If you're just rendering with the FirePro, it won't really matter. Rendering isn't particularly PCIe bandwidth intensive.

 

[nanaki333]

Yeah. I was referring to if you were going a tri-SLI or something like that with a bunch of 980 Ti cards. That should definitely work and I highly doubt you would notice any difference if you had a 5930k to drop in to test with a 5820k. especially with the pcie3.0 lanes You won't notice any real hit with the x8 on a card. https://www.pugetsystems.com/labs/articles/Impact-of-PCI-E-Speed-on-Gaming-Performance-518/ - not quite a 970 but close in performance (and I'm using that to show your gaming GPU in x8 mode).

 

[Timmah!]

I would go 5930k. How i envy you, lol. Not that i need new machine myself, but since i recently started to get some interest in this stuff again, cause of the need to get new GPU, i can feel that itch to waste some heavy monies on this shit...i may end up with GTX980Ti, but sure as hell i would rather have 2 of those, alongside new mobo, 32gigs of RAM and that 5930k... oh well :-D

The amd+nvidia card can work together in DX12

Anandtech just did a great article on it. make sure the AMD card is the "leader" though.

thanks all ..sounds like the general consensus is that i am little future proof if i go with 5930K, but one firepro+one gtx shoul still be fine for my needs with 5820k.

i guess the decision is made. wish i had jumped on the fry's deal for $277 for 5820k now !!
