ZOTAC GTX 970, 980 Omega & Extreme Overclocking Video Card Hands-On

Following-up on our GTX 980 benchmark and review that went live yesterday, board manufacturers now have their own variations on the new Maxwell cards up for sale. Most of the manufacturers have altered the design in some way: a cooler overhaul, pre-overclocks, heavier-duty capacitors, and additional pins for power are a few of the common changes. Zotac has done all of these with their “Amp! Omega” GTX 970 GPU we got hands-on with.

Zotac’s new GTX 980 and GTX 970 both ship in standard (unmodified GPU specs + aftermarket cooler), Omega, and Extreme editions. The Omega and Extreme GPUs host a suite of OC-tuned hardware features and a slightly boosted clockrate.

In our hands-on with Zotac’s Omega video card, we determined that the device hosts a full-steel outer casing with aesthetics-only “rivets” to produce a more solid look and feel. The Omega uses what Zotac calls its “IceStrike” cooler – available in dual- and triple-fan configurations – combined with “exo armor,” effectively a backplate. The Zotac backplate ditches nVidia’s reference design removable airflow channel, though this is theoretically unnecessary when using a dual push-fan configuration (as opposed to the blower fan used in the reference unit).

Exposed in the backplate are three covers for clusters of solid capacitors. The covers are largely for appearance, but should also help in thermal reduction across the caps. Using solid capacitors theoretically improves overclocking headroom by reducing voltage ripple, cap thermals, and improving overall stability.

An “OC Plus” micro-USB slot is also present on the board. Using an included micro-USB cable, users can plug the video card directly into the motherboard and use Zotac’s “FireStrike” software for real-time voltage and CLK monitoring. This should be more accurate than using hardware sensors that talk to software, but we’ll have to test it to truly know.

The memory clock on the Omega GTX 970 is about ~36MHz faster than base (7010MHz), with the BCLK overclocked to 1102MHz (1241MHz Boost) over the stock 1076MHz / 1216MHz. It’s a few steps difference, but not a huge jump. We’ve previously found that pre-overclocks are generally fairly ineffectual in video cards, but will test the 970 to see if that remains true this generation.

Zotac’s stock GTX 970 runs the same spec as nVidia’s GPU spec, but has different outputs. The stock 970 opted for 2xDL-DVI, 1xHDMI, and 1xDisplayPort (as opposed to 1xDL-DVI, 1xHDMI, 3xDP). This helps reduce cost.

The GTX 970 will sell at $330 (MSRP); the GTX 970 Omega Edition is targeted for $380. You’re paying an extra $50 for the cooler, OC features, and pre-overclock. TDP on the Omega card has increased to 171W due to the fan and OC config (over 145W).

As for the Extreme edition, well, we’ll have one in-hand soon. The Zotac GTX 970 & 980 Extreme cards host a triple-fan configuration; intake is positioned centrally and flanked on either side by fans that are channeled to exhaust heat out of the sides of the video card. This Extreme Edition card also has a breathing LED that changes based upon GPU load (we’re unsure of the threshold). The LED glows red when under duress and green when performing more intensive 3D gaming tasks – for those who don’t want more lights, yes, it can be disabled.

Zotac’s GTX 970 Extreme card will ship at a 176W TDP over the 165W base. The 970 Extreme will clock in at 1203MHz / 1355MHz boost with a 7200MHz memory clock over the 1076 / 1216MHz boost stock with a 7010MHz stock memory clock. That’s a fairly substantial OC.

The stock GTX 970 and 980 units should already be available under a Zotac tag. The Extreme and Omega GPUs will ship shortly. We’ll have reviews of all of them, so stick around before buying.

Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.'"

First world problems, Steve. First world problems.
