GeForce GTX 770 serves up GK104 in Titan-style package for $399


— 8:00 AM on May 30, 2013

The first member of the GeForce GTX 700 series is barely a week old, and already, Nvidia has added a second offering to the lineup. Say hello to the GeForce GTX 770, which is coming out today at a more affordable $399.

This card is based on the same GK104 graphics processor as the GeForce GTX 680. It shares many of the GTX 680's key specs, but the reference core and boost clocks have been cranked up to 1046MHz and 1085MHz, respectively, and the memory speed has been raised to 7 GT/s. As you'd expect, these increases have taken their toll on the card's power envelope, which has fattened up to 230W (compared to 195W for the GTX 680). Here's how the specs compare at a glance:

GeForce GTX 770 35 139 139 3.3 4.3 224

Radeon HD 7990 64 256 128 8.2 4.0 576

The higher clock rates give the GTX 770 a small but substantial advantage over the GTX 680, especially in the memory bandwidth department. Considering this card will cost $399, while the cheapest GTX 680 at Newegg is priced at $419.99, that's not a bad proposition. We'd expect the GTX 770 perform very similarly to AMD's Radeon HD 7970 GHz.

There's much more to the GTX 770 than higher reference clocks, though. This card includes the same premium, Titan-style cooler as the GTX 780, which is one of the quietest cards we've ever tested. Considering the GTX 770 has a tighter thermal envelope than the GTX 780, chances are it will be just as quiet, if not quieter. Also, the GTX 770 features a refined boost algorithm that accounts for temperatures as well as power utilization. There should be plenty of extra headroom in this bad boy on top of the higher reference speeds.

In fact, Nvidia's partners have a gaggle of superclocked GTX 770 variants ready to go, all with clock speeds well above those of the reference card. Take a look:

  Base clock

Asus GTX770-DC2OC-2GD5 1058 1110 7010
EVGA GTX 770 SC 1085 1137 7010
EVGA GTX 770 SC ACX 1111 1163 7010
Gigabyte N770OC-2GD 1137 1189 7010
MSI GeForce GTX 770 Gaming 1098 1150 7010
MSI GeForce GTX 770 Lightning 1150 1202 7010
Zotac GeForce GTX 770 1059 1111 7010
Zotac GeForce GTX 770 AMP! Edition 1150 1202 7200

You'll find pictures of some of these cards in the image gallery below.

We don't yet have pricing for all of the cards above, but Asus and Gigabyte tell us their superclocked GTX 770 variants will be priced at $409.99 and $409, respectively. Also, while all the models listed above have 2GB of GDDR5 memory, Nvidia is allowing partners to double up. We know Zotac has a 4GB card with 1059/1111MHz base and boost speeds on the way, and there are probably others.

The only downside is that the GTX 770, like the GTX 780, doesn't come bundled with a free copy of Metro: Last Light. Nvidia started including that game with GeForce GTX 660 and better graphics cards last month, but for some reason, the offer doesn't extend to the GTX 700 series. Strange.

In any case, we expect to have a review of the GTX 770 for your perusal some time in the hopefully not-too-distant future. We've been too swamped with other upcoming products (*cough* Haswell *cough*) to do the GTX 770 justice in time for today's launch, but we'll do our best to get this thing benchmarked as soon as we're able.
