My mini review of the new i7-4790K (Devils Canyon)

Recommended Posts

As some of you know I was previously running an FX-8350 at 4.5ghz, All my other system specs are exactly the same on my new system as all the parts besides the CPU and motherboard were re used or the exact same model, I'll start off with both system specs.

My old System specs

FX-8350 at 4.5ghz Cooled by H110

Biostar TA 970x motherboard

MSI 770GTX 4GB

8GB G.skill ram  at 1866Mhz 

1TB Segate HDD

Windows 7

Corsair 800 watt PSU

 

My new system is 

I7-4790k at 4.4ghz(stock turbo speed) Cooled by new H110

MSI gaming 7 Motherboard

MSI 770GTX 4GB (reused)

8GB G.skill ram at 1866Mhz(new but exactly the same model)

1TB Segate HDD,(new but exactly the same model)

Windows 7(new copy)

Corsair 800 watt PSU (reused) 

 

Overall the performance difference is huge I can run the exact same settings in P3DV2 and average about 15-20 FPS higher on the 4790k over the 8350 even though the 4790k is clocked 100mhz slower.(For now :diablo:)

 

This build cost me about $800 to do, but would have cost about $500 if I had reused all the parts. I figured for the $300 difference it was worth it to buy new parts so I could keep a very capable AMD powered rig running. I still have my old 660ti laying around and will install it in the AMD system.

 

If your on a tight budge get the i5-4690K its $239 and should easily OC to 4.4ghz,

 

If you are running a Haswell CPU already there is really no point in upgrading to the 4790k unless your chip is a  very poor overclocker.  At 4.4ghz in P3D V2,  my temps never got above 48C so the new TIM seems to be working. I love my AMD rig and she has served my well for the past two years and my last 3 gaming pc's have been AMD powered so it makes me rather sad to see that AMD has fallen so far behind. AMD says in two years they are going to release the next generation of FX series chips and, I hope they give Intel a run for its money. Because even if your an Intel fann boy you still should want AMD to succeed otherwise, Intel will have no reason to develop new CPUs and will raise prices on current ones.

 

So would I recommend a switch to Intel for AMD users? Yes, but if your on a very tight budget $169 for 4ghz FX-8350 is hard to beat, since in many games such as Battlefield 4 the 8350 will perform just as well as the 4790k, but FSX and P3D are heavily dependent on single core CPU performance and that is where the Intel chips shine!

Thanks a lot Dave. I am ready soon for a similar upgrade. Are you running hyperthreading on or off?

For now on, I'm gonna turn it off at some point and see how it effects performance but as of now I have p3d set to run on 7 of the 8 threads and it seems to help with texture loading.

hi david do you think that the performance boost youre getting with your new Rig on P3D is because of your cpu or gpu upgrade ? 

cheers

EDIT : i did not see that you used the gtx 770 on your old rig . i guess i answered my own question

I'm still debating whether I'm actually going to buy a 4790K + mobo or not. After getting my 6GB GTX 780, I'm extremely happy with the performance of literally every other game I've tried with it besides FSX. Just trying to decide if it's actually worth another $500+ solely to make FSX run a bit better than it does on my i7 860 @ 4.0...

Hey ryan , Im currently on the verge of getting one is yours this one : http://www.amazon.com/gp/product/B00K699CRW/ref=s9_simh_gw_p147_d0_i1?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-4&pf_rd_r=0EJN7GTTVS9EQGA7GEX1&pf_rd_t=101&pf_rd_p=1688200482&pf_rd_i=507846

if yes then do you think its worth it ?? 

cheers

Been waiting to pull the trigger on a  4790K. But not convinced yet it will outperform or clock any better than a SB 2700K. reviews are very mixed if not disappointing. New TIM over the 4770 is all Im reading, but temps stills arent good. I understand a noticeable performance improvement over an AMD. I have an upgrade in the cart at Newegg.

Very nice! What stepping is that chip??

What I have read is, that due to better glue it should run a little cooler than 4770k, but performance about the same. Maybe there is room for a little more OC, but there will of course be differences between samples. But if you come Sandy Bridge or later, there is little reason to change.

What I like though about the 4790k is the 4 GHz stock freq.

Best regards

Batch L418C134.

If it worth it , it depends what you expect, i do a lot other stuff with my Cpu.s.

You can have 100-200mhz difference depending on the MoBo, example Gigabyte Z87-OC to Asrock Fatality Killer Cpu -200mhz mem -400mhz, ASUS Hero -100mhz on CPU memory no diff to the Gigabyte board the Cpu was the same 4770K and Corsair Platinum 2666 CL10.

I think its the same on Z97 shall flash my Z87 Hero and Chek, this test is done on a Gigabyte Z97X SOC Force.

I've been considering an upgrade every year since 2011 when Sandy Bridge came out but none of the more recent chips will give a big enough performance increase over my 4.9Ghz 4700k. Looking around I think Devils Canyon will give about 20% better if the same overclock is achievable. Just not worthwhile. I think it will be a big step over an 860.

 

Hopefully Broadwell will be the way to go for me.

Sorry, should have said 2700k.

The 4790k also has more capacitors to help even power distribution which helps with oc I don't know of any 4790ks that can't hit and be stable at 4.7 GHz but there are plenty of 4770ks that can't even hit 4.4ghz,I'm aiming for 4.5 to 4.6ghz so I can keep my vcore low and prevent degradation.

I7 4790k I am thinking of getting it because at stock speed 4.0 like i7 2600k at 4.5 overclocked. Still, think my i5 3570k with midrange settings will be fine for fsx. Broadwell likely be incremental anyways like i7 4790k. I don't overclock anyways and run sliders full right and i7 4790k factory clock at 4.0 and turbo at 4.4 looks enticing. FSX feeds on CPU speed we all know this.

Broadwell should get 5.0 GHZ ???? possibly with safe oveclocking. Devils Canyon ( were did they get that name from ) 4.0 GHZ without over clocking.

Still, 85% of the time overclock not needed at medium to high settings in fsx. Flying in New York overclocking useful, but no point using it flying in Alabama or Arizona photoscenery with rex textures at 1024. I7 4790k for non overclockers it's good thing for them they get 85% what overclockers get.

I upgraded from a 3.9ghz 860 to a 4770k @ 4.5ghz, using 2133 cas 9 ram and a gtx 660 ti for both systems. The performance boost was worth it IMO; most notably taxing and take off is no longer a 15 fps stutter fest. Things only got better when I upgraded to a gtx 780 3gb.

Today I ordered my production 4790K today along with Gigabyte Z97-UD5 Black Edition motherboard. Will re-use my HyperX RAM, and my near-new GTX780OC-3GB. The engineering samples we had were pretty good, I am hoping to get around 5GHz stable with my EVO212 cooler.

Ryan, I went from an i7-930 running at about 3.6GHz to my current i7-3770 non-K running at 4.4GHz and saw a decent enough improvement. I am hoping that Devil's Canyon can take that to 5GHz, I see where you are coming from RE and 860 at 4, I still think a 4790K at 4 would outperform it based on architecture improvements, and if you can get 5, then that's a real improvement over the 860. Ask RSR to "sponsor" you a new rig... perhaps. B)

4790K_Validation_zps8f3ee94c.jpgHi everyone,

 

Just wanted to share my findings on the 4790K. In short, I've purchased 6 different Haswell CPUs that I've used over the past year or so in client builds and best OC has been 4.7GHz. My first purchase of the 4790K has gone well so far:

 

  • 5.0GHz (stress tested Aida64 9 hours; 25 passes with IBT). I'm certain it can clock higher
  • Batch Number: L336D105 (Micro Center, Chicago, IL)
  • 1.40Vcore
  • Disabled Hyper-threading (I always disable HT)
  • Delid
  • Liquid Metal between die and Intel heat spreader
  • Cool Jag TIM between CPU and XSPC Raystorm waterblock
  • Swifttech MCP35X Pump
  • Dual 240MM rad
  • 2 ASUS Poseidon GTX 780s SLI

Ok guys I currently have it OC'd at 4.5ghz (as I don't really need anymore p3dv2 hits my 38FPS limit in almost any situation) and my current stable Vcore is 1.140v with temps in OCCT on the mid 50c range and temps in p3dV2 in the mid 40c range. To anyone new at OC'ing a cpu make sure you tune your voltage manually I used the auto setting and it would run the Vcore up to 1.22V during OCCT tests and cause my peak temps to be in the low 70c range. By tuning it manually I never got above 60C and averaged in the low 50s. Basically the auto setting throw to much voltage at the CPU.

 

She does great with the Carenado Phenom at 11s with full autogen and every shadow turned on I never got below 25FPS compared to the low of 14 FPS with the FX-8350 with all the autogen set to normal and only cloud,vehicle and interior shadows turned on. Im also finally able to run HD rex clouds which look awesome.

z06z33,

this topic has caused me to make the same switch. I am expecting to get all the parts in the next two days!

Have a 8350 running at 4.4GHZ

GTX 760 4GB

h80i

1600mhz cl11 16gb memory

120GB Samsung SSD

1TB HHD

 

I was having no problems playing literally everything, but P3dv2 just isn't working. ANYTHING past default causes drops well below 15. Carenado programs are the worst, tbm850, phenon100, sr22. Unusable, total waste of money...

 

So I decided to just replace everything. 

 

New case

got a h55 to replace the h80i with in the amd computer

herovii mb

4790k

16gb 1600mhz ram cl7

And a GTX 970 SC

Two new 512GB SSD's 

 

I am hoping this will finally be enough to play all of my add-ons and finally get some eye candy (traffic, weather, etc)

I am super excited to yield the benefits!

 

I am starting to get the hang of what runs fsx and prepar3d best, despite all efforts, multi cpu's just aren't the important thing. 

 

FSX cpu performance is directly correlated to passmark's singe thread performance test, and Prepar3d isn't far off. According to that a G3450 single threads 25% better than a 8350 and I would bet the house it performs +-5% of that figure. 

 

The G3450 is a $90 processor.....

I get a near constant 40fps on the ground and 50-70 in the air in the Carenado C182T(G1000s) and in the low 30s in the TBM850 while on the ground and 50-60 in the air. This CPU has changed everything. I'm thinking about getting the GTX 980 to get another 10 fps or so in P3D.
