4670k to 4790k, no fps boost at all.

[TenjouTenji]

Just bought a 4790k off a carbie. Had a 4670k at 4.7ghz. Got this 4790k to 4.7ghz as well. I tested gta v and rottr before hand at 4k res. Fired up the games this evening for testing and fps has literally stayed the same. Disabling HT also made no difference. Min fps also the same. It's as if there's a gpu bottleneck, but it's a 1080ti aorus extreme. Would have rather just kept the i5. Research however suggests in should be getting 10-20% better frames. Any ideas?

Temps are around 62c under load at 1.32v. So no throttling.

Time to SLI dual Aorus Xtreme 1080ti's, do it, do it!!!

Interesting thread... Watching.

I can't even say it's smoother. General "microstutter" still hits every now and again. I was hoping to at least eliminate that part.....
Going to do a fresh windows install tonight. Been a while since I did that. Will update.

I realise a 1080ti shouldn't be a bottleneck for GTA5, even at 4k, but to compare CPUs I would start with running the game at 1080p and/or turning down detail settings to "exclude" any possible bottlenecking that might be happening.

Have you run any synthetic CPU benchmarks to make sure that CPU is performing as it should?
The microstutter is weird; What speed is your ram?

 

[CarboVan]

Upping rez reduces cpu bottleneck. Not sure about the actual mechanics around it, but its true
Like iamgigglz said, at 1080p you should see a bigger difference.

Cinebench I get 945cb. Ram is Corsair Vengeance 1600 9-9-9-24, XMP enabled.
CPU running as it should given the CB score.

Going to do another round of tests at various resolutions after my windows re-install. I get off work at 1pm today so will be soon
Hopefully someone here can submit their FPS with similar setups.

The only games I currently have are:

Dota2
Wolfenstein 2
PUBG
Overwatch
Rise of the Tomb Raider
GTA V
Grim Dawn
CS:GO

Will probably test everything.

I wouldn't expect to see a performance gain. You haven't really upgraded, just moved sideways.

Moar ghz would see a slight impact but you'd hit the limits of your CPU only if you were gaming at 1080P and even then, there isn't a massive difference between the two CPUs since you both have them at the same ghz.

Sorry dude, if you want to see gains, upgrade to an 8700K but even that might not be worth it.

I did a lot of reading before I decided to switch it up. I didn't have the budget to get new board + ram. The single core performance on the i7 should have seen at least a 10% increase. I would have been happy with 5-7fps increase overall. But it literally stayed exactly the same. The single core is supposed to be stronger on the i7 versus the i5, even at the same ghz, simply from better architecture. Multi-threaded performance should be 50% faster. Sadly I didn't do Cinebench on the i5 before I sold it. Wish I had....

If I don't see any gains after the install, then so be it. I'll just accept it and move on. I'm keen on Ryzen maybe later on in the year. I do 3D renders and graphics / web design etc. so I'll benefit there quite a bit.

Ok so no real FPS gains from re-install, although windows is nice and responsive

There are zero architectural differences between 4670K and 4790K. They are same Haswell generation. There is no IPC differences between the two.

If your playing @ 1080p then your resolution is the bottleneck for a 1070-1080Ti.

~95% of games are more GPU bound than CPU.

Also if you've not OC'ed your RAM, that will be a bottleneck. Ideally you want 2400Mhz for a OC'ed 4th gen i7 + 1070-1080Ti.

https://www.youtube.com/watch?v=frNjT5R5XI4 - in this vid you'll see how a 2500k @ 4.6Ghz with 1600MHZ RAM VS 2500k @ 4.6Ghz & 2400Mhz RAM gets ~30% increase.

For gaming, the diff between a 4770k-8700k @ ANY Ghz is very VERY small in 95% of games. GTA5 does show a fairly handsome improvement on newer architecturte as do more CPU board games. IMHO its not worth the cost what so ever. Get fast RAM and enjoy . Watch the vid's I posted, you'll have a better understanding of why I said everything in this post.

Just bought a 4790k off a carbie. Had a 4670k at 4.7ghz. Got this 4790k to 4.7ghz as well. I tested gta v and rottr before hand at 4k res. Fired up the games this evening for testing and fps has literally stayed the same. Disabling HT also made no difference. Min fps also the same. It's as if there's a gpu bottleneck, but it's a 1080ti aorus extreme. Would have rather just kept the i5. Research however suggests in should be getting 10-20% better frames. Any ideas?

Temps are around 62c under load at 1.32v. So no throttling.
