We already published a review back in August of the Zotac GeForce GTX 780 AMP! Edition. Because of the poor performance and very high noise levels, we (and other review sites) were understandably not particularly positive about the Zotac card. Newly released firmware now claims to solve these issues, so of course we wanted to give the card a second chance.
When it was first released, Zotac described its GeForce GTX 780 AMP! Edition as the fastest GeForce GTX 780 on the market. And the specs were promising indeed, with a standard clock frequency of 1,006MHz, a Boost clock of 1,059MHz and a memory clock frequency of 1,552MHz. In spite of those impressive numbers, Zotac's card underperformed in the benchmarks compared to the other GTX 780 cards we tested.
A thorough analysis of the card's BIOS indicated that Zotac used much less aggressive Boost values than the competition. Much worse were the high noise levels of 41.6 dB(A) when idle and 50.9 dB(A) under load (measured from 10cm away). But noise has afflicted most of Zotac's AMP! cards over the last few years...
We informed Zotac of our findings, and were promised a solution. So two weeks ago we suddenly received a new card with the request to put it through our testing procedure again. Zotac has also configured new BIOS settings which are supposed to make the card faster and more silent.
The specs and features of the second Zotac GeForce GTX 780 AMP! Edition are identical. If you want to read more about those, please check out our original preview. Via the link below, you'll find the benchmark scores of the original card and also the new card, so you can clearly see what has changed and what hasn't.
