Nvidia GeForce GTX 1000 Series (Pascal) MegaThread: FAQ and Resources

The first number is usually the phases for the GPU, whereas the second number is the phases for the memory and other minor stuff. That's at least how it works with motherboard, I'd assume GPUs are the same way. I think there are even more phases than what they show, realistically it's something like x+x+x+x, but the first number is primarily important. How good those phases are also plays a role, the number does not mean everything.

that makes sense and kind of what i was thinking anyway. so now how do i look at a pcb pic and count these phases?

The GTX 1070 has a 4+1 power phase:

The GTX 1080 has a 5+1 power phase:

Not precisely sure, but usually you'll notice 4 or so things that look identical and are in a patternal configuration.

I'm so glad you found that image. I must have spent close to an hour looking for it again after seeing it a few days ago. Where is that from?

Really? It's literally at the top of Google Images when I searched "power phases". :lol:

I used Yahoo.

 

[TechyInAZ]

Of course, I tend to lag behind a bit in my games list, refusing to pay full price on new releases.

Oh good....I'm not the only one on the planet who doesn't rush out and spend $50-$60[US] on a new game release.:lol: The only exception for me is in racing games like the F1 and NASCAR series. Fortunately there are good guys on early release Beta buys (Assetto Corsa, Project Cars, DiRT Rally cost me $40 vs. their $60 retail release..AC is going to be released in August for the PS4/XBone).

You play F1 too!? Sweet, I'm not alone. 😀

I'd like to ask can an AMD Phenom II X4 955 handle the GTX 1080?

no, you should get a rx 480

that is beyond max it can handle, but you can always swap it into a new build

those in the yellow box (chokes as they called them in the pic) is what i was thinking of that i could count.

@17 seconds, i know how many phases many of the cards have, i can read it n the specs and pr stuff for the card. my concern is for cards that don't list it anywhere. as i noted above, specifically this is the pcb of the zotac amp cards. they don't list the phases anywhere nor has it been noted by a reviewer. the pic is all i can find to workoff of.

i want to count the phases from this pic so i can update the cards specs. that's what i am asking about. if i use the chokes (in yellow on the pic turkey showed) to count, then it's nice and easy. it's what i was thinking but wanted to be sure that's actually what i am supposed to be counting would be 10 + 2 (if those 3 off to the right of the pcb count). that's a lot of phases but the ftw card has 14+3 so i guess it's not too ridiculous of a number for a card. looking for someone in the know to throw me a bone and explain how to count them.

 

[turkey3_scratch]

In that picture, Math Geek, it looks unidentifiable since there seems to be that black heatsink covering some stuff. Well, it looks like it's covering only the mosfets. I can't tell. Actually, I have a feeling it is 8 phases maybe.

 

[Math Geek]

thanks for the try. i'll keep looking into it. i'm sure somewhere out there is an explanation that will get me to the answer i'm looking at reviews and their pics and those chokes seem to match up to the reported number of phases, but i do want to be sure before spouting off info i don't know is right.

thanks again. i'll get there eventually. not most important thing just a bit of ocd on my part to not have incomplete specs.

 

[turkey3_scratch]

Just ask InvalidError, I'm sure he can identify it.

 

[Math Geek]

figured him or onus could shed some light on it. i'll contact them directly and see what they can add to this.

Thank you for your answer!
I would like to buy a video card with 8GB memory and my problem with the RX480 it has not got PhysX!
So, I have to buy some NVIDIA card!

here is a chart from a review of the new x4 845 cpu paired with a 1080 from guru3D. as you can see it holds back the 1080 quite a bit. your cpu is even older and weaker and would hold the card back much more. it may still be playable but you'd be wasting a lot of the 1080's power.

whole review is here http://www.guru3d.com/articles_pages/amd_athlon_x4_845_fm2_review,1.html

 

[Math Geek]

looks like zotac going mini for the 1060 card and not a super ultra mega extreme amp edition http://videocardz.com/62073/zotac-geforce-gtx-1060-amp-and-mini-detailed

plus some more 1060 rumors and leaked benchmarks http://videocardz.com/62086/nvidia-geforce-gtx-1060-rumors-part-5-full-specs-2-0-ghz-overclocking not quite the "beats a 980" nvidia said at first, but solid performance.

Not sure if this is the right thread to ask, but I'm looking to upgrade from my EVGA GTX 980 SC ACX 3.0 to a 1080 and wanted to know which 1080 is the best. Money is not an issue, but when I buy my card I want to know that that I bought the best card available especially since SLI and Overclocking are things I might do with them, but overall I just need them to be powerful and fast.

Edit: Forgot to mention, my CPU is an i7-4790k. Will this be enough or should I start looking for the next big CPU for this to all work properly.

 

[Math Geek]

this is the right thread

so far not a single 1080 has been able to outperform the others. they all hit the same speeds at the same performance levels. really you're picking one that has the right look and price for you. perhaps an extra or 2 thrown in makes the difference. free game or something. you can look at some of the reviews from page 1 of this thread to get an idea but literally every card was the same 5-10 fps better than the FE and ran cool and quiet.

I am partial to EVGA, but I would wait for the second round of 1080s to come. As has been mentioned many times on the Pascal discussions, the first releases of a new GPU almost always have issues and need bugs to be worked out. In my case, I waited on the second round for 970s and got EVGA SSC ACX 2.0+ GPUs for SLI. It was a much better card than the original ACX superclocked variants.

And your CPU is fine. These days, especially at higher resolution and quality settings, CPU speed is not as important as GPU power. I have proven that running my 4690K overclocked to 4.7GHz and stock at 3.5GHz (both on all four cores) with benchmarks.

 

[Math Geek]

speaking of evga did anyone else notice that they released a ftw card with stock clock speeds? same price as ssc but you get the dual bios and the double power phases of the ftw card. then oc it yourself. i posted it to the main list but did not mention it here i don't think

 

[10tacle]

No I somehow missed that. Very interesting. Dual BIOS is one thing I like about my cards.

 

[Math Geek]

dual bios let's me play around with custom bios and not risk bricking the card. i like the idea of the card if you're comfortable oc'ing it yourself. save $40 and get the better pcb over the other evga cards.
