Because nearly everyone dont know how much better is new skylake in games vs sandy bridge and still think sandy bridge=can match skylake in game i run some tests...

I already posted this in skylake owners klub, but every day someone ask how skylake is performing vs sandy bridge and he get answer its small difference so i creating this Thread.

Also use Frametimes and comparable FPS as primary.Fraps is here just for min FPS.

Test system:
2500K 4.5Ghz
8GB 1600 8-9-8 1T
GTX970 1500/8000
win7 64

6700k 4.5Ghz
16GB 2937 CL15 1T

If GTX970 dont bottleneck there is masive gain in games like crysis3-more than twice faster than 2500k
watchdogs 60%
skyrim 47%
WOT 37%
Witcher3 37%

Thats a nice comparison, but I'd like to know if you have a i7 2600K on hand, could you do the test comparing it with the 6700K or disable HT on the 6700K and run it like a true QC chip and then make these tests as these do not compare the gaming performance jump between a quad core and a quad core or a quad core with HT to quad core with HT.

i can give you an idea with a single 290 and my i7 Sandy . . . C3 1080 HT on and off . . .

Thank you for the comparison +rep.
I am shocked by the increase in Skyrim. From 38 to 56 fps, that's a 48% increase in a game that doesn't scale well with HT, impressive results there. I guess it is that DDR4-3000 memory. When I increased the memory from 1333 MHz to 2400 I got 10-15% jump with my i7 870. What mods are you exactly using that make the 2500K tank in cities?

Heyy....hope the trip was good. But what I find lacking in the findings is that the OP says that there is no reason to move from an i5 2500K (a quad core part) to a 6700K (a quad core with HT). I'd like if he can show these benches either with an 26/2700K or disable HT on his 6700K and then run the benches again. Otherwise, it's a solid comparison.

from sandy (i5 and i7) to skylake . . . i think it is really worth it unless there is some newer coming out soon. ddr4 cost is going down and that's another thing.

your country is beautiful. i am going back. thank you.

very nice compression! but it's not fair enough.. 4 Cores VS 4 cores + HT ... If you can test with HT off so 4 core vs 4 Core basically ( 2500K vs 6600K )

HT ON/OFF its same.Only in crysis3 and watchdogs are differences.Its GPU bottleneck with skylake.(skylake is too strong for GTX970 even with HT OFF)

i7 6700k 4.6Ghz

Thats ALL
HT scalling calculated with FLA calculator
witcher3-44%
dying light- screenshot 27%.
dying light- test scene 13%
far cry4- screenshot 5%
far cry4- test scene 6%
watchdogs- screenshot 26%
watchdogs-test scene 46%
crysis3- screenshot 41%
crysis3- test scene 60.5%
GTA5- screenshot 5%
GTA5- test scene 3%
also note that skylake have improved HT so older cpus like sandy bridge will have less HT scalling.

Well this is some user with i7 6700k clocked at 4.5 and gtx 980ti 1430/8100
And this is mine with same settings and same card clock.In that scene i've got 108 fps and he 90 fps

Fantastic comparison! You put an effort, well deserved +REP.

However, I would like to point out one thing:
Please do keep in mind that what actually really helps in CPU-bound situations, is the huge throughput difference of the different RAM kits. Since asking you to do it all over again is ridiculous, please do pick a game or two where the differences are massive, but try to run the DDR4 kit in a configuration that provides similar performance to your DDR3 kit. This will further help establish the differences which come from the CPU architectures alone.

But what's the point when the memory upgrade is part of the same architecture upgrade?

When you go from a i5 2500K to a i7 6700K there is no way you can keep your old memory, you will need to go to faster DDR4 anyway..
