How We Tested
Nvidia's GeForce GTX 980 is one of the most powerful and energy-efficient graphics cards we've ever tested. It's a product we tested in depth in "Nvidia GeForce GTX 970 And 980 Review: Maximum Maxwell". Those of you unfamiliar with the GeForce GTX 980 are encouraged to read that piece for detailed GPU info and game benchmarks. In a nutshell, the GTX 980 is about as fast as the GeForce GTX 780 Ti, with a much lower 165 TDP and a $550 MSRP.
Today, we're focusing on Zotac's GeForce GTX 980 AMP! Omega Edition and what differentiates it from other models on the market. To that end, the emphasis is on the cooler's thermal and acoustic performance. Then, we'll examine power usage and test overclockability. All of this data will be compared to the reference GeForce GTX 980 design.
Graphics cards like the GeForce GTX 980 require a substantial amount of stable power, so XFX sent us its PRO850W 80 PLUS Bronze-certified supply. This modular PSU employs a single +12V rail rated for 70A. XFX claims continuous (not peak) output of up to 850W at 50 degrees Celsius.
We've almost exclusively eliminated mechanical disks in the lab, preferring solid-state storage for alleviating I/O-related bottlenecks. Samsung sent all of our labs 256GB 840 Pros, so we standardize on these exceptional SSDs.

"which allows us to provide a stable higher factory clock setting without reducing the lifespan of the components of the graphics card"Reply
Almost everyone needs a GPU upgrade in less than 3 years. Who cares about the lifespan if it is more than 3 years?
i'm currently using the 970 version of this card. sweeeeeettttReply
It's ridiculous to see this card doesn't provide the actual OCing experience one hopes for. Out of the box OC is good, but one simply doesn't expect it to be enough, atleast not for the card in the OCing segment of the brand. This was supposed to be a OCer's card, it failed on those terms. Too many software-bound restrictions. But yes, the hardware does look quite appealing.Reply
did you try the nitro boost switch to see if that unlocks the locks. I would hope for a fw or software update.Reply
Not impressed with the Zotac at all.Reply
I bought an EVGA 980 ACX 2.0 (1266 base clock, 1367 boost), it scores 14260 for
the Firestrike test just at default settings, it's a proper 2 slot card, much quieter
(the fans don't turn on until the GPU goes over 65C) and from what I've read will
oc better. Also, in the UK the EVGA card is 35 to 40 UKP cheaper; I can't imagine
why anyone would buy the Zotac.
Don, did you try using Afterburner instead for the oc tests?
So zotac goes and over engineer's the hell out of a 980, adding LN2 dip switches, Voltage Readouts, Beefed up power delivery, High performance inductors, and then what do they do?Reply
They lower the TDP by 11%, when compared to the Nvidia Reference Model. Whats the use of LN2 features if your going to handicap the voltage cap?
My reference 980 hit 1.5ghz with ease. 1st try overclock actually. And reference board is using the cheapest coils and inductors money can buy.
What is the point of this monstrosity of a card? It has an oversized PCB and massive 2.5-slot open air cooler and isn't any faster, cooler, or quieter than Nvidia's reference design. GM104 is only a 165W chip and Zotac designs this huge overkill cooler and it's no better than Nvidia's rear-exhaust design AND takes up 3 slots? What a joke.Reply
I'm skeptical that the 980 needs such a beefy cooler, even when overclocked.Reply
Seriously people, you sound like the kind of people that would buy a $100,000 muscle car, then bitch that you can't turn it into a formula dragster and still drive it on the street. This card is seriously overclocked already and yet people still want more, with an intact warranty. Spoiled much?Reply
