NVIDIA took the wraps off of its latest-generation Geforce GTX 770 GPU last week, and manufacturers have begun announcing not only reference designs but custom and factory overclocked versions of this GK-104 "Kepler" GPU refresh. One card in particular that caught my attention was the ASUS GTX 770 Poseidon graphics card, which combines NVIDIA's GK-104 GPU with a hybrid heatsink and fan combo that allows the simultaneous use of water and air cooling!
According to the branding, and a hands-on report by Tech Power Up at Computex in Taipei, Taiwan, the GTX 770 Poseidon graphics card is part of the company's Republic of Gamers (ROG) line and likely sports beefy VRM hardware and factory GPU overclocks. Of course, the GTX 770 GPU uses NVIDIA's Kepler architecture and is essentially the GTX 680 with some seriously overclocked memory and refined GPU Boost technology. That means 1,536 CUDA cores, 128 texture units, and 32 ROPs (raster operation units) within 4 GPCs (Graphics Processing Clusters). This is the full GK-104 chip, desite the x70 name. For more information on the GTX 770 GPU, check out our recent review of the NVIDIA GTX 770 card.
Update: ASUS has just launched the new ROG graphics cards at a Computex press conference. According to the ASUS press release:
"ROG Poseidon graphics card with hybrid DirectCU H2O cooling
The new ROG Poseidon graphics card features an NVIDIA® GeForce® GTX 700 Series GPU and a hybrid DirectCU H2O thermal design that supports both air and liquid cooling. Developed by ASUS, its CoolTech fan combines blower and axial fans in one design, forcing air in multiple directions over the heatsink to maximize heat dissipation. Liquid cooling reduces operating temperatures by up to 31 degrees Celsius for cooler running with even greater overclocking potential. ROG Poseidon also features a red pulsing ROG logo for a distinctive dash of style."
Back on the Poseidon specifcally, the card is a short GTX 770 with a distinctive cooler that uses a full cover water block that covers the entire card and includes the GPU, memory, and VRM areas. ASUS further added a more-traditional air cooler to the area above the GPU itself to help dissapate heat. The air cooler is a circular aluminum fin array with a fan that sits in the middle. The air entire hybrid cooler is then covered by a ROG-themed shroud with a configurable LED-backlit Republic of Gamers logo on the side that can be controlled via software.
The water cooling portion acts as any other full cover water block, allowing cool water to move heat away from the metal contact (the bottom of the block) touching the various components. The inlet and outlets poke out from the side of the card, which is a bit odd but the shroud prevents them coming out at 90-degrees like typical blocks. If your case width is tight, you may need to get creative to fit a 90-degree barb extender (I apologize if that's not the technical term) on to the existing tubing connectors (heh). The cooler can be operated with the air cooler's fan running with or without being connected to a water loop. When water cooling is used, the fan can be turned off to reduce noise or left on to allow for higher overclocks and/or lower temperatures.
Unfortunately, that is all of the information that is currently available
as ASUS has not yet officially launched on the custom GTX 770 graphics card. Pricing, availability, and clockspeed details are still unknown.
For more information, stay tuned to the press.asus.com/events livestream page as it might be announced at a Computex press conference this week since the company is showing off the hardware at the show!

Galaxy recently made its custom factory overclocked GTX 770 graphics card available. The new card is not the fastest GTX 770, and doesn't quite embrace the supa-pipe as much (as Josh would say), but it looks to be a good deal all the same, giving you a quieter HSF and a decently-overclocked Geforce GTX 770 GPU for $399.99.
The Galaxy GeForce GTX 770 2GB (77XPH6DV6KXZ) takes NVIDIA's GTX 770 GPU with 1,536 GK-104 based CUDA cores and overclocks it to 1110 MHz base and 1163 MHz boost clockspeeds. The 2GB of GDDR5 memory is only clocked at the reference 7010 MHz, however.
The card has the same video outputs as other GTX 770 cards: two DL-DVI, one HDMI, and one DisplayPort output. The card with its dual slot, dual fan cooler is 10” in length and requires a 600W PSU at minimum (not solely for the GPU). It needs one 8-pin and one 6-pin PCI-E power connector.
Galaxy provides a two year warranty for the card. It is available now for around $400 at various retailers.

Not to be left out, GPU partner Zotac has announced its own set of graphics cards based on NVIDIA's GK-104 GTX 770 GPU called the GTX 770 and GTX 770 AMP! Edition. Both cards come with Zotac's custom dual fan cooler and have some impressive factory overclocks. In fact, the GTX 770 AMP! Edition is the fastest factory clocked GTX 770 so far, and is the only card to feature overclocked memory.
The Zotac Geforce GTX 770 features a GPU base clock of 1059 MHz and a GPU boost clock of 1098 MHz. It will be available with either 2GB or 4GB of GDDR5 memory. In either memory configuration, Zotac is keeping the GDDR5 at the stock clockspeed of 7010 MHz.
Meanwhile, the GTX 770 AMP! Edition has GPU clockspeeds of 1150 MHz base and an impressive 1202 MHz boost. However, the GTX 770 AMP! does not only feature an overclocked GPU, but overclocked memory at 7200 MHz.
The chart below compares the two Zotac graphics cards.
|Zotac GTX 770||Zotac GTX 770 AMP! Edition|
|GPU Base||1059 MHz||1150 MHz|
|GPU Boost||1098 MHz||1202 MHz|
|Memory||2GB or 4GB||2GB|
|Memory Clock||7010 MHz||7200 MHz|
Both of the Zotac graphics cards also come with a Splinter Cell game bundle that includes three (digital download) games:
- Splinter Cell: Double Agent
- Splinter Cell: Conviction
- Splinter Cell: Blacklist (will be release later this summer)
As far as pricing and availability, the GTX 770 (ZT-70301-10P) is on sale now at Newegg for $400, but the 4GB GTX 770 and GTX 770 AMP! have not yet been released by the looks of it, and Zotac has not announced official pricing or ship dates yet. More information can be found here. The AMP! Edition has some impressive factory overclocks, and the benchmarks should be interesting.

Now that NVIDIA's GTX 770 reference graphics card is official, the various partners have begun unleashing their own spins on the hardware. Unlike the TITAN, NVIDIA is allowing custom PCBs and coolers, making the selection of GTX 770 cards much more diverse and unique.
In fact, EVGA has a slew of GTX 770-based graphics cards planned for 2014. Out of the gate, there will be two graphics cards available to consumers: The GTX 770 and the GTX 770 Superclocked. Both cards will come equipped with the company's new ACX cooler. In addition, the GTX 770 FTW, GTX 770 4GB, GTX 770 FTW 4GB, and the GTX 770 Classified 4GB cards will also come with the ACX cooler and will be available later this year. Details on those last four cards are still unknown, but EVGA has provided specifications on the first two, which will be available soon.
The EVGA GTX 770 w/ ACX
The EVGA GTX 770 w/ ACX is a GK-104 “Kepler” GPU clocked at 1046 MHz base and 1085 MHz boost. The card also features 2GB of GDDR5 memory clocked at 7010 MHz.
EVGA is also introducing a Superclocked edition of the GTX 770 that will use the new ACX cooler. This GTX 770 ACX Superclocked has factory overclocked speeds of 1111 MHz base and 1163 MHz boost. The 2GB of GDDR5 memory remains at the reference clockspeed of 7010 MHz.
Both of these cards use EVGA's new ACX cooler which uses a new heatsink design paired with two fans (dual ball bearing) and a back-plate that is reportedly lighter, quieter, and cooler-running than the reference cooler.
The EVGA GTX 770 4GB Classified GPU with ACX cooler. It is listed on the site, but not available yet.
The EVGA GTX 770 ACX and GTX 770 Superclocked ACX will be available soon for an as-yet-unannounced price. The Superclocked edition has some impressive factory overclock numbers, though it will likely come at a premium. The other interesting takeaway from the EVGA announcement is the confirmation of 4GB GTX 770 cards coming in the future. More information can be found on the EVGA product page.

NVIDIA recently unveiled its GTX 770 GPU. Sitting between the GTX 680 and GTX 780, the Geforce GTX 770 is a refined GK104 with higher clockspeeds and improved GPU boost. It features 1536 CUDA cores and a 256-bit memory bus.
While the stock GTX 770 comes clocked at 1046 MHz base and 1085 MHz boost, ASUS is factory overclocking its DirectCU II OC card with a maximum boost GPU clockspeed of 1110 MHz. The 2GB of GDDR5 memory on the card will come clocked at 7010 MHz.
The differentiating factor here (aside from the overclock) is the custom DirectCU II cooler. ASUS has fitted the overclocked GTX 770 with a DirectCU cooler that uses copper heatpipes that directly contact the GPU and attach to an aluminum fin stack. The heatsink is, in turn, cooled by two 80mm fans. ASUS claims that the GTX 770 DirectCU II OC is up to 20% cooler and three-times quieter than the referrence NVIDIA cooler. Other features include a 10-phase DIGI+ VRM, and “Super Alloy Power” capacitors, chokes, and MOSFETs. The dual slot card is 10.7” long and includes two DL-DVI, one HDMI, and one DisplayPort video ouptut. ASUS' GPU Tweak software will allow users to adjust core and memory clockspeeds, voltage, fan speeds, and the power control target.
The ASUS GTX 770 DirectCU II OC is shipping now and will be available at retailers soon. In fact, the card is avaiable at Newegg right now for just under $410.

$400 is a tempting number, much less expensive than the $650 price tag on the GTX 780 and right in line with the existing GTX670 as well as AMD's HD7970. You will probably not see many at that price, $450 is more likely as there will be very few reference cards released, all manufacturers will be putting there own spins on the design of these cards, which brings the price in line with the GTX680. Performance wise these cards outpace the two current single GPU flagship cards, not by enough to make it worth upgrading from a 7970 or 680 but certainly enough to attract owners of previous generation cards. [H]ard|OCP reviewed MSI's Lightning model, with dual fans, an overclock of 104MHz on the base clock and 117MHz boost, plus a completely unlocked BIOS for even more tweaking choices.
If you want to see how well it fares on our new Frame Rating metric you will have to read Ryan's full review here.
"NVIDIA debuts the "new" GeForce GTX 770 today. The GeForce GTX 770 is poised to provide refreshed performance, for a surprising price. We evaluate a retail MSI GeForce GTX 770 Lightning flagship video card from MSI with specifications that will make any enthusiast smile. The $399 price point just got a kick in the pants."

GK104 gets cheaper and faster
A week ago today we posted our review of the GeForce GTX 780, NVIDIA's attempt to split the difference between the GTX 680 and the GTX Titan graphics cards in terms of performance and pricing. Today NVIDIA launches the GeForce GTX 770 that, even though it has a fancy new name, is a card and a GPU that you are very familiar with.
The NVIDIA GK104 GPU Diagram
Based on GK104, the same GPU that powers the GTX 680 (released in March 2012), GTX 670 and the GTX 690 (though in a pair), the new GeForce GTX 770 has very few changes from the previous models that are really worth noting. NVIDIA has updated the GPU Boost technology to 2.0 (more granular, better controls in software) but the real changes come in the clocks speeds.
The GTX 770 is still built around 4 GPCs and 8 SMXs for a grand total of 1536 CUDA cores, 128 texture units and 32 ROPs. The clock speeds have increased from 1006 MHz base clock and 1058 MHz Boost up to 1046 MHz base and 1085 MHz Boost. That is a pretty minor speed bump in reality, an increase of just 4% or so over the previous clock speeds.
NVIDIA did bump up the GDDR5 memory speed considerably though, going from 6.0 Gbps to 7.0 Gbps, or 1750 MHz. The memory bus width remains 256-bits wide but the total memory bandwidth has jumped up to 224.3 GB/s.
Maybe the best change for PC gamers is the new starting MSRP for the GeForce GTX 770 at $399 - a full $50-60 less than the GTX 680 was selling for as of yesterday. If you happened to pick up a GTX 680 recently, you are going to want to look into your return options as this will surely annoying the crap out of you.
If you want more information on the architecture design of the GK104 GPU, check out our initial article on the chips release from last year. Otherwise, with those few specification changes out of the way, let's move on to some interesting information.
The NVIDIA GeForce GTX 770 2GB Reference Card
Tired of this design yet? If so, you'll want to look into some of the non-reference options I'll show you on the next page from other vendors, but I for one am still taken with the design of these cards. You will find a handful of vendors offering up re-branded GTX 770 options at the outset of release but most will have their own SKUs to showcase.
