Another interesting set of benchmarks:

Make of it what you will. I must say I was surprised to see my 5960X's multi-cored results still up there with the best. Also, these benchies were achieved at processor stock speeds. Different story with the single-core results. However, comparing value for money against performance gains the 5960X's halo still continues to be somewhat lacking in lustre unless, of course, you regard that initial investment as now being vindicated in terms of confirmed future proofing. Overall I continue to be very happy.

I have had the i7 4770 for 3 years and a half now, so think its time to upgrade.

Now I see its a different socket.

 

Will it be a matter of just remove the 4770 and put the 7770 or I need a new board?

 

LGA 1151 vs LGA 1150

 

 

These might help answer your question:

Perhaps a BIOS/UEFI update might get you where you need to be, but I'm not certain about that. Suggest you do your own research before deciding.

You already gave the answer yourself, your 4770K uses the 1150 socket, the 7700K needs the 1151 socket. So yes, you need a new board and new RAM, as it also includes a switch from DDR3 to DDR4 RAM. The only mainboards might be working with a BIOS update are those for the 6700K series, e.g. mainboards with a Z170, H170 or B170 chipset.

5GHz on air is not that crazy. My 4790K is at 4.9 on a NH-D15. That said, this is a pointless upgrade for anyone on Haswell and newer.

I have an ancient i7-2700K o.c. to 4.8 Ghz, stable for years now.  Base on this bench mark the i7-7700K will only give me an 8% improvement.  I would not want to spend thousand on new CPU and MB/RAM for marginal improvement. I will wait until mine croaks out and then get the 9900K

I disagree - there's plenty of IPC/generation changes through the last 6 years. You'd yield more than 8%

Ya, I suppose so.  Thanks for all the info.  The trouble is mine is still kicking.  Benchmark aside, it's the real perf. with what I have that is the proof.  Will wait and see more reports come in.

2700k-6700k, 7700k difference in fsx bench 25%

Not have any SB or Ivy chips , had a couple of good 2700k and 3770k

The oldest chips a have today is Haswell keept to good 4770k and 4670k dont find any better 4790 4690 chip.

Have a 1.35v 5ghz Skylake 6700k and KabyLake 7350k retail and 7700k ES and retail

Not sure but it seems that the ES OC better most do more tests can be that the retail chip is not a lucky draw.

Anyway if you shall uppgrade now go for the 7700K very easy to OC for the NOB.

I would strongly advice to wait until Ryzen has been released.

I am getting a new computer built.  The 7700K is around $350 vs the 6950 is $1500.

I know the 6950 has more cores, but the 7700 can be OC higher.  Which would be better for P3D?

7700K.  CPU speed is king in simulators.

Agree!

 

Even for games, 4 cores is still where it's at.

$1500 v $350? I can't imagine that the performance difference (if there is any at all) is worth anywhere near $1150.
