i7-7700K vs i7-4770K benchmark

Recommended Posts

Hi,

 

Seems like 2017 is the time to upgrade my older 4770K@4,7 to i7-7700K.

 

Out of the box it looks like a 30% boost with a "5 GHZ" relative easy to clock given another 6%.

 

So if we expect todays FPS at 30FPS it should provide about 40-41fps

 

Not bad at all

 

Maybe also 2-5fps extra with DDR4@3200MHZ RAM vs DDR3@2400MHZ

 

So 30FPS is almost 50fps (hopefully  :wink:  :Tounge: )

I read on several sites that the 7700K indeed can be oc to 5GHz on air cooling

If your 4770K is running at 4.7,  that will be an increase of 7%, not 30% :(

The faster ram should indeed give a few fps on top

In the test above is seems like single thread is about 30% faster out of the box but that is offcause compared to a none overclocked 4770K.

 

My mistake  :Tounge:

 

Seems like it is more about 21% (15% at 4700MHZ+6 at 5000MHZ) + DDR4 % (more like a 25-30% increase overall)

I'll have to see if there will be 7th gen for 2011 v3, I personally think it is the best work horse for FSX or P3D

Im not sure about change my i5-4670k.

 

We´ll see AMD Ryzen and the number of cores used by the new 2017 sims.

5.0 GHz on air? On all threads and stable?

 

Call me skeptical but I'd have to see that (from multiple different consumers) to believe it.

Could be running at 85C on air. That's hot thought. My clock ran 85C on air on my 3820 but I got liquid cooling and with FSX running I generally get about 45-55C

I also hope this, actualy i´m using a 6850K at 4,4 Ghz and 3200 Mhz DDR4 with a GTX1080 and a 500 GB M2 ssd.

never hat so good Performance.

 

The first time in my flightsim live that i dont think about upgrading something to have more Performance. And i´m flight siming since 15 years.

From what I've read, if you delid the 7700k, add a dab of liquid metal, temps can be lowered by 30C, and OC's on water can get over 5.2 stable, and that's out of the gate, just getting started.     Since the current P3D is thread manager limited on Core 1, The only thing that's gonna help Scotty's "moar power!" orders is GigahUrtz, and this CPU is very promising in that way.  I am considering it.

Look at the Videos I posted in the other thread. Also, Asus have confirmed that 5 GHz is indeed achievable with "reasonable" cooling for a chip that's "reasonably" placed in the silicone lottery. 

 

The OC3D Videos I posted by Tom Logan are worth a watch. He achieved 5.1 GHz stable with an AIO with his chips. Not sure about his fish, or kebabs. 

 

 

Still, Asus' reputation for rock-solid reliability and overclocking performance continues with the Code. It is a high-end motherboard with a high-end price to match, but it (along with several other Asus boards) has a neat party trick: it can push the i7-7700K to 5GHz with a reasonable (read: no extravagant water cooling required) setup. There are a few caveats to that performance—the biggest being that Asus also supplied the i7-7700K for this review, which was likely binned from a large batch—but the company claims that most decent unlocked Core i7 and Core i5 Kaby Lake chips will hit 5GHz between a reasonable 1.29-1.35 volts.

The CPU market is depressingly stagnant these days :sad: I can think of only one reason to buy a new desktop PC at the moment, and that is a total failure of my existing one.

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:

https://ark.intel.com/products/97129/Intel-Core-i7-7700K-Processor-8M-Cache-up-to-4_50-GHz

 

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  :Devil:

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.
