6800K vs 7700K for simming

Recommended Posts

Looking for opinions on a 6800k vs the new 7700k for simming.

 

I understand that 7700k will be slightly faster for mainly single threaded games such as GTA V / Battlefield etc there are tons of benchmarks for highly single threaded games  , but what about CPU heavy games that also take advantage of multi threading like X-Plane/FSX/DCS/P3D?

 

The other thing I'm considering is if the X99 boards are a dead end, will there be a 7800k (or whatever it will be)?

 

I'm using Oculus VR  so I want the best performance on sims. Currently using an aging 3930K running @ 4.2Ghz  it does ok but I've pushed this system as far as it's going.

I would think that the 6700K would do better than the 6800K for flightsimming.

 

It would still be my number 1 choice..

Thanks Bert. Are you running a 6700K currently?

 

I've not built a new PC in 6 years so haven't worried much about the newer stuff, but 4 generations past mine should yield a decent performance gain. Already have the 1080 GTX , just need the CPU to feed it.

7700k without a doubt. Despite being a 6xxx-level processor, the 6800k is a Broadwell gen processor. So with the 7700k, you'll have 1.5 to 2 IPC improvement cycles (while Broadwell is now 2 cycles/generations behind Kaby Lake, it's not clear what the IPC improvement over Skylake is) on top of the fact that you can hit the high 4s and perhaps 5.0Ghz mark.

If it's purely for gaming and simming, a 7700k is literally the best you can buy right now. I run a 6700k with a Vive and I get excellent performance in both P3D and X-Plane, and the 6700k pretty much matches the 7700k clock for clock so it isn't a bad option either. You won't be gaining anything from those extra cores and cache as far as gaming is concerned. Plus, Z270 boards are cheaper than X99 and the platform is newer. Unless you do content creation or have need of lots of PCIe lanes, then 6700k/7700k is the best option.

Of course this is a no brainer.  The 7700K is cheaper than the 6800K; out of the box it is at 4.2GHz (you have to do nothing); the optimized default setting will take you to 4.5GHz; and with ASUS (the board I have), you can overclock it automatically to a stable 5.0GHz.  Anything less, like the 6800K, can be overclocked to maybe a stable 4.8GHz but it requires some expertise.  The only downer I know of is the fact it requires Windows 10 but some on Google have been able to get around that requirement.  You should definitely see an increase in performance from the 3930K.  I just upgraded from a 4770K.

 

Benchmarks are at the following link - http://cpu.userbenchmark.com/Compare/Intel-Core-i7-7700K-vs-Intel-Core-i7-6800K/3647vs3607.  It cremated the 6800K.  Do not let anyone talk you out of a 7700K!!  You will need a new motherboard (the x99 will work but recommend the Z270) but everything else in your current system should work in the new setup.

 

See my specs for my setup.

 

Best regards,

Jim

Hi,

 

I depends what you are looking for.  I have recently gone from a 4790k @ 4.5 to a 6850K @ 4.2.   If you are looking for a pure FPS then the 7700K or 6700K might be your best bet.  If textures not popping in and out is important and having other things running in the background (AS16, GTN, etc) is important to you, then having the larger cache and extra cores may be valuable to you.  All I can say I am pretty pleased with my new system.

 

Hope this helps

Agree.

 

Worth mentioning though that that only 80% of 7700K's will overclock to 5 GHz, dependant on the silicone lottery.

 

Five Way Optimisation, which is what Jim is referring to is very good in my opinion. With the latest BIOS on my Z170 board the overclock is identical to my manual overclock.

 

 

 

You will need a new motherboard (the x99 will work but recommend the Z270)

 

 

 

No! X99 will not work, it's the wrong socket. Z170 or Z270 is required for Kaby Lake. X99 is LGA 2011.

I just bought a 6700k rig. Actually two weeks ago I had a 7700k in my hands but the machine arrived broken (pre-built) so I had to send it back. They had no replacements so I got a refund and saw a great offer on a 6700k machine and thought why not. I went for it and it saved my 500 USD and came with 32gb RAM instead of 16gb which was with the more expensive Kaby lake machine. From everything I have read, there is almost zero difference and I couldn't be happier. I almost let pride get the better of me in wanting to have the newest and 'best' with Kaby lake but in the end common sense won out. If you can get a good deal on a Skylake processor/motherboard, go for it. Better to save money and upgrade in a few years when the 'true' next gen of processor and tech comes along than burn money on clever marketing.

Excerpt that Kaby Lake overclock's higher than Skylake, 5 GHz plus to be specific. According to Asus 80% of 7700K's will do 5 GHz with reasonable cooling.

 

The other thing that may sway people of course is the advantageous additional features that come with Kaby Lake. Optane etc. It's not just performance.

 

I built my Skylake system before Kaby was released, but yes, like you I'm happy too.

Thanks for the correction.  I knew that and still wondering why I said what I said.... :smile:

Thanks for all the feedback. I believe I'll be going with the 7700k. I used to go with the higher end stuff all the time but the line is blurred these days when it comes to sims and the cost vs performance by all accounts seems to be better on the 7700k at substantially less cost.

 

Now just to decide on a Z270 board.  There is a dizzying array of choices -  time to do some homework.

@ Newegg, the Asus boards are getting some bad reviews with burnt CPU's and graphics cards. I used to purchase exclusively Asus but after 2 failed GPU's and 2 failed motherboards I have stayed away (their support wasn't great). OTOH lots of site are saying how good their overclocking features are. 

 

Wondering about the MSI Titanium as I haven't had any MSI board before. My current board is a Asrock and it's been relatively trouble free but I hate to say it their newer boards seem rather lackluster. I just want something that will last and can overclock easily, could care less about all the new LED lighting etc as I never have the window side of me PC where I can see it anyways.

 

It's so hard to get honest reviews these days, half the sites look like shills with no real info on how the boards they are reviewing really stack up against each-other. They get review samples they get to keep so of course you can see how that goes....

I have a 7700K and she runs great. Runs stable at 5Ghz and P3D has never been smoother.

I went with the Asus ROG XI Code motherboard. Probably a bit over the top, but it does the trick.

Do we know for sure that the failed CPU's and graphics cards were "definitively" caused by issues with the Asus motherboards? Are there any known motherboard issues that are proven to be causing this?

 

Or are these individuals just speculating? we have to be very careful about angry owners and their unproven assumptions.

 

Personally, I have only ever had one issue with an Asus motherboard in many years. True that their support isn't good at all. Last year Asus won an award for least RMA's.

The Asus ROG Code does look nice. I'll have to think on it.

 

It's been about 8 years since I last purchased Asus because I had 2 480Gtx cards from them fail and they gave me the runaround until the warranty was up and I ended up stuck with 2 junk cards.

 

If they have better QA maybe the situation is improved. Going to look for more feedback on other sites than Newegg.

So none of the newer cpu's will work with my Asus Rampage Extreme X99 board?

Yes, feedback on sites re broken CPU's and GPU's doesn't mean there are issues with Asus boards that are killing those components. It looks like it is indeed just angry owners looking for something to blame.

 

If Asus boards were killing CPU's and GPU's it would be a major issue that would be all over the net, a major controversy.

X99 is socket 2011. Kaby Lake is a different socket. Kaby will work with Z170 and the new Z270 boards.

6800 series will even though its using 14nm process like kabby lake its a generation behind. I was searching for info if there would be a 7xxx series for X99 boards but haven't found a definitive answer. I read on another site that the next extreme chips would be using a different socket entirely and part of the reason I posted here.

I agree.  It is a shame people do this.  I heard Amazon has started new screening procedures to make sure the people making reviews of products are actual owners.  Even if an actual owner, things happen and does not mean the boards are bad.  Now, if mine goes, I'll be back here and I'll be really mad too!  :smile:

Newegg does exactly that. You can filter verified product owners. I exclude any remarks or reviews from people who didn't actually own it.
