[Techno-Kitchen] i7 4790K@4.7Ghz vs. i7 5930K@4.7ghz + GTX980Ti@1300mhz SLI in 4K!

[hawtdawg]

You might notice they're running @4K on those games, not 1440p.

then why in the hell would the CPU matter in a far more GPU bound situation?

 

[Jacky60]

I have to build a 5960x system right now! Been pretending I didn't need it.

 

[Jacky60]

They are putting plenty of volts into both platforms but I'm pleased someone is still doing these tests. I can believe these results as GTA5 and Crysis 3 work all my HT cores to the bone.

 

[Sabrewings]

Well one could also argue that once dx12 hits, the iGPU might actually become useful for say physics calculations. Then a quad with iGPU will be way faster than a hexa-core or offer better effects.

While this is possible, it's still up to individual developers to take the time and have the expertise to implement.

 

[alcoholbob]

That's why the test was with 2 980tis instead of 1. To shift the load back to the CPU.

 

[imaheadcase]

Then the "rest of us" means those that have the attention span for a 3 minute video and can do simple math, which I've broken down in this graphic. Clearly each game is 20%+ faster:

Can't tell if serious or trying to troll.

 

[hawtdawg]

That's why the test was with 2 980tis instead of 1. To shift the load back to the CPU.

But I was already talking about SLI 980ti's. 2 of them @ 1454mhz and 1440p coupled with my 3770K@4.6 shreds everything I've thrown at it, like 100fps+, and I have HT turned off. Why would going to 4K suddenly create a CPU bottleneck? I'd like to see a trusted review site take a shot at this, because other than this video, I haven't found anything that really supports that kind of performance difference between the K and E CPU's.

I'm gonna have to download Crysis 3 and see how it runs. If an OC'd non-E series CPU is a bottleneck, it's not with the vast majority of games.

 

[omek]

It seems that a percentage of the difference is probably going to the 8x/8x and lack of pcie lanes. I'm wondering what the difference looks like with one 980Ti both platforms @ 16x obviously turning the detail off or running it at a low res.

 

[ZGR]

I'd be much more interested in seeing a similar video comparing the 5820k vs the 5930k and see how dependent these benchmarks are with PCIe lanes. I definitely feel like my i5 is near its limit with GTA V at 60fps with one GPU.

A better benchmark would be an intense ARMA 3 scenario with matching settings between the systems and having the NPC's play for each run.

But suggesting X99 for entry level gamers is a waste of money; especially for those who are content with 1080p60.

 

[Innokentij]

After alot of digging i finaly found a game that can show the difference betwen Z97 and X99. Is this best case scenario? Probably! Would i buy or recomend x99 to anybody here in Norway? Hell no!

5820k 3718kr
Kingston HyperX Fury Black DDR4 PC21300/2666MHz CL15 4x8GB 2895kr
Asus Rampage V Extreme 4099kr

total 10712kr / 1312.37 US Dollar

if u want 5930k it's 5849kr bringing total to 12843kr / 1573.44 US Dollar (And hellz yes u want the 5930k not the 5820k)


Kingston HyperX Fury Black DDR3 PC15000/1866MHz CL10 2x8GB 939x2 = 1878kr
Intel Core i7 4790K 4,0GHz 3099kr
Asus Maximus VII Formula 3590kr

total 8567kr / 1049.58 US Dollar

Now if u can settle for the 5820k it's not that bad, just ddr4 being pricy. But i bet a OC'ed 4970k will stomp that 5820k.

 

[beginner99]

true and it will probably limited to AAA titles, which the 3 tested all are. IMHO this is actually a must for AMD Gaming Evolved to at least make use of their own iGPU when paired with AMD GPU. That would be a real value-add. Even better if it also works with Intel but that would be counter-productive for AMD.

As a poster on page 1 said: needs to be tested on 5820K. Maybe it's a simple PCIe issue (eg. amount of lanes). Maybe these games do need 2x 16x speed. But then if you can afford 980ti SLI you probably can also afford to go beyond a 5820k.

And also don't forget that it depends on the games. In SC2 I bet the 4790k will be faster. But then you would be dumb to have an SLI setup anyway...Still, might be important to mention this for complete newbies.

 

[njdevilsfan87]

They have my interest, but we need more science on this. I'd like to see this repeated with a 5820K, and a pair of AMD GPUs as well. If this turns out to be a PCIe bottleneck, that's not good news for Skylake which is no longer rumored to be using PCIe 4.0 but 3.0 instead?

 

[Rvenger]

I have a 5820k and I am mulling over getting another 980ti.

 

[Dave3000]

Would it be wiser to buy a 5930k instead of the 5820k if you are going to be SLI'ing current high-end video cards because of the more PCI-E lanes? Is PCI-E 3.0 x8 already a bottleneck for GTX 980ti video cards?

Only if you can cool the cards well with them jammed together in pcie slots 1 and 2. X99 boards are limited to 16x/8x if you skip a slot and use slots 1 and 3, so there's no difference between the 5820k and 5930k in that regard.

X99 really has poor SLI spacing. z97 SLI boards for example have the same gap between pcie spots 1-2 as x99 has between 1-3.

Yes, without a doubt IMO. I'm not even saying that with regards to gpu performance. You never know when you're going to want to throw in a NVMe SSD or something that will soak up the additional lanes.

That chart has nothing to do with the platform difference. Look at the resolution, this is purely a CPU bound benchmark and would not at all tell us the difference those extra PCIe lanes are making.

 

[alcoholbob]

Umm...no.

Way to go! You found a non reference board! Good job buddy! Ports 1-2 on those boards are still closer together than Z97 on that board! Good job owning yourself!

I'm not even sure how to respond to such stupidity...You do understand the two cards would be in the first and third red pci-e x16 slots correct? How close the first and second are is irrelevant. Tri and Quad configurations will be jammed right up next to each other no matter what board someone uses.

 

[Madpacket]

Lol

Lmao. You are one for calling someone stupid when you didn't even read my original post. You do realize the third port is 8x right? In the end all you managed to show is somebody has to buy a 10cm SLI bridge and is STILL stuck at 8x on a CUSTOM X99 board that's $400 to achieve slightly more spacing than Z97. Amazing you managed to find one minor point in my post (about z97 spacing) and went all the way out to find an expensive custom board to invalidate *one* of my points while quoting my ENTIRR POST as if invalidating one minor quibble invalidates everything I said, then calling me stupid.

You must think correcting spelling mistakes on someone's post also invalidates everything they posted! Congratulations on owning yourself again!

 

[Sabrewings]

Watercool your CF/SLI setups. /Spacing issue.

If you look at the photo the first and third spot is the one that is running x16 not the second, that one is limited to x8. Nothing wrong with him pointing out a solution.

Yeah but it sure does show that it's not just the PCI-E that matters in overal comparison, the cpu and added ddr4 plays a role to, i was watching a youtube video where they already showing that in tri SLI on the "old" 980 more lanes is better and the card is performing better on 16/16/8 then 8/8/8. Also crysis 3 already showed good improvment on 16/16 vs 8/8 in that video to.

Here is the video if u interested.
