Today we take a look at the new Gigabyte GTX 1080 G1 Gaming graphics card featuring a custom triple fan cooling system, out of the box enhanced clock speeds, improved power phase delivery alongside an RGB lighting system. This card is one of the higher end models available today and is priced accordingly, at £599.99 inc vat.
Gigabyte incorporate the latest iteration of their Windforce x3 cooling system, which in previous tests has always performed well. The card ships with a backplate and adopts an enhanced 8+2 power phase delivery system. Gigabyte also supply some proprietary software to support overclocking and to adjust the lighting system. We will look at this in more depth later in the review.
In a similar fashion to the ASUS Republic Of Gamers Strix GTX 1080 the Gigabyte GTX 1080 G1 Gaming ships with a software adjustable RGB lighting system.

The Nvidia GTX1080 ships with 2560 CUDA cores and 20 SM units. The 8GB of GDDR5X memory is connected via a 256 bit memory interface. This new G5X memory offers a huge step up in bandwidth, when compared against the older GDDR5 standard. It runs at a data rate of 10Gbps, giving 43% more bandwidth than the GTX980 GPU.
The Gigabyte GTX 1080 G1 Gaming RGB can operate at different clock speeds, controllable in the latest version of their Xtreme Engine Software. In Gaming Mode base clock is set at 1695mhz, and in OC mode base clock is 1721mhz. Boost clock speeds are 1835mhz in Gaming mode and 1860mhz in OC mode. We test the card today in the faster OC mode, which can be set in the software by clicking a button.
I’d like to hear Kitguru’s take on:

Makes me wonder how widespread this is, and if they’ve experienced or suspected this from cards they’ve reviewed.
Such small gains might seem meaningless, but when cards are priced the same, from the same model, have similar cooling/oc headroom capabilities and power draw, that slight performance edge can sway sales and reviews.
GIGA sent higher clock sample than retail?
Interesting, thanks for sharing. I haven’t reviewed the MSI cards yet, so I can’t comment on the clock speeds. The asus GTX 1080 strix card we had seemed to be all set at the retail speeds you buy in a store. I have an ASUS 1070 GTX STRIX with me now, but i haven’t started testing it yet.
“No coil whine’ –> you never know if another card will have it or not.
My FE GTX 1080 did a lot better at 4k then this card, odd!

Actually its normally related to the capacitors, so its generally a design related issue for each specific board.
So where can I buy one? There’s no stock anywhere in the UK! :<
There was also a review of the Asus GTX 1080 Strix OC on this site. Conclusion was ‘no coil whine’. In the meanwhile several reviews wrote that it had a little coil whine. And one guy an a forum had one with really load coil whine. So there is that.
with the stupid high prices they are charging for the cards id say waith a few weeks and see what amd come up with cause 400-450 pounds uk for the 1070, the successor to the 300 pond when released 970 is way to much money for a card that isn’t their 1080 flagship.
yours is a good chip maybe, better boosting??
I had two of these… incredible amounts of coil whine. I’ve never heard anything like it! Tried two PC’s across a few different power supplies. Plat Plus. Avoid like the plague.
