Two gtx 1080 strix ?

[enki364]

Hi guys, I'm going to buy an gtx 1080 strix from asus, but in the site where i want to buy it there are two type:
The first one has:
Clock GPU 1936 MHz
Memory clock 2000 Mhz

The second:
Clock GPU  GPU Boost Clock : 1733 MHz GPU Base Clock : 1607 MHz
Memory clock 10010 Mhz 

(If I can, i will post the link of the site)
The question is why they have the same name, but they have a deep difference in clock speed of gpus and memories ? And which of these two vga I should take to have a better gameplay on a resolution like 3440x1440 ?
(The first one cost 100$ more than the second )

One of them is factory overclocked. By the cheaper one and overclockd it yourself.

But why the factory overlocked has only 2000 mhz of memory clock and  the other that need to be overlocked has 10010 Mhz, there is a difference of 8010 Mhz beetween them O_o

I'm not exactly sure why this happens, but often when memory speeds are presented, they are actually only 1/4 of the effective memory speed. so when its saying it has 2000MHz speed, it really is 8000 MHz (which is normal). For example, my 980ti is often represented as 1800 MHz on my monitoring programs, but is actually 7200MHz.

 

Not sure why it does that, but that's a very common practice.

 

EDIT: looking at 1080 specs, it should be 10000MHz, so maybe for some reason this card scales by 5 times, instead of 4 times (probably something to do with GDDR5x or new GPU architecture). so 2000MHz becomes 10000MHz.... again, no idea why it does that. But its very normal for things to be listed that way.

If it has 8000 Mhz, there is still a difference of 2010 Mhz, so the question is the memory clock change something, as it regards the performance ?
And  I was wondering wich is the best gtx 1080 custom, in terms of performance ?

don't worry too much about the "BEST" 1080... they will all perform pretty similarly, and you will be able to get pretty much the same overclock with any 1080 GPU on the market today. No one has released a GPU that is particularly outstanding yet. Get whichever one looks the best, or is the most affordable, or has whatever features you deem useful. they will all perform about the same (within a couple %)

 

As far as that 8000MHz thing, go read my edit up there.

One of them is listing the effect clock, and one is listing the normal clock. Google it to see what that means, I'm on mobile so I don't want to type it an explanation of the difference.

So if a buy the factory overlocked gpu   I won't have lower performance ?

[Zyndo]

no. if you buy the factory overclocked GPU, you will get higher performance than stock. its overclocked. it will be better. if you're doing your own manual overclock, odds are you can get very similar numbers to if you manually overclocked the factory overclocked version...

 

But to more directly answer your question, the factory overclocked one performs better than the one without an overclock.

Thanks for the answer, I think i will buy the factory overlocked, and i hope that the memory clock will not change anything

Here's the thing. Those 2 card are basically the same, BUT the first one have been factory overclocked, mean that if you put it in your computer and dont do anything else, it will run faster than the other one just put into the computer and dont do anything else with it either.

But, as for overclocking yourself, it's entirely depend on the silicon lottery. Meaning that depend on your luck the non-factory overclocked could end up overclock better than the factory overclocked one, or vice versa. That's why we call it "silicon lottery", because it depend on luck.

As for the 2 version of the ASUS Strix 1080, I think the website you are looking at make a mistake or something, because on ASUS website both card is listed with 10010 MHz Memory Clock. So dont worry about the memory clock.

I have seen the same, in the asus website it has 10010 Mhz of gpu clock

[Zyndo]

the memory clock speed is definitely 10GHz.... don't worry about it.

No certainly not. Again though, I would recommend buying the cheapest version and overclocking yourself. Overclocking gpus are VERY easy.
