Zotac GTX 680 Amp! review TechPowerUp

Here's a review of a highly O/C'd 680 for those interested. $579 retail seems a bit steep, IMO. Styling is definitely not it's strong point even though I get the impression it's supposed to be. 😉

It guarantees 10%+ oc on both core and mem. That deserves at least a 10% hike making it $550. If at $580 they can keep them in stock, and if these oc better and have better cooling, then $580 is justified.
 
This OC'd worse than all other 680s listed in the review, including the reference model. Not very compelling IMHO. The memory OC was good though, but the core numbers were disappointing.
 
Paying 80$ for a OC which is almost guaranteed on a stock 680 is a complete waste of money IMO.
 
Still no voltage control, terrible. This card is no better than reference performance wise, like every custom 680 out there, the only benefit is a better air cooling solution.

Lots of ref 680s clock just the same and better. Both of my reference cards have better results than this card.

When are we going to see a non-ref 680 on the market for sale that offers performance characteristics better than we see in reference models ? :thumbsdown:

Agreed, reference GTX 680 is the way to go. Honestly, the oc scaling didn't seem too great either





4.7% gain is not worth 80$, reference is the way to go IMO

That is overclocking above the overclocked cards default 1111 MHz core / 1652 MHz memory. They said the card is about ~7% above reference, and then an additional ~4.7% was gained from the overclock above 1111MHz to 1130 MHz core (2% overclock) and 1895 MHz Memory (14% overclock). So totally 7% + 4.7% gained over the reference 680 (overclocking the card further).

Not really sure what you are trying to say here....

Per the review:
Zotac max GPU clock: 1130mhz
Reference 680 max GPU clock: 1147mhz

I will take the reference...

This will change, depending on the card. My 680, in stock form, is defaulted at 1006 MHz like all the others, and will boost to a max of 1110 MHz. Overclocking through offset, +155 will get me a max boost of 1266 MHz, but +155 offset to another card won't take it to the same boost. Kinda sucks how it works.

Too bad, another voltage locked card. My $500 reference also outperforms this card, boosting to a max of 1266 MHz, I don't see how the price is justified seeing as the board on this card is reference too, same 4+2 phase. Asus and EVGA are the only ones so far who will offer voltage adjustments in one way or another. That Zotac Extreme edition card adjustable up to 1.5V or whatever will probably only be sold in Asia, I've read.

My impression is that most reviewers almost never push the cards, but only overclock them to see how well performance scales with higher clocks. I doubt that overcloking aggregates from these reviews show the average potential of a video card.

That would be the chip, wouldn't it? Either just a bad one, which seems strange on a factory O/C'd card. Or, this is the only chips available to buy from nVidia to make your custom cards. It's not like there's a lot of spare GK104's floating around.
 
how can TPU give it a "9.5/10 highly recommended" when it's OC potential is so low?
but the memory overclock is surprising. the new generation of card from both camps really love the new GDDR5 chips.

I agree, though NVIDIA could just as easily introduce GK110 at $700+. They'd likely get away with it too until AMD catches up to them early 2013.

All we need is some better drivers and we should see some better performance out of the 7970 IMO.


EDIT: I meant more consistant performance.
