MSI recently announced the GTX 770 Gaming 4GB which combines a factory overclocked GK-104 GPU with 4GB of GDDR5 memory and the company’s Twin Frozr IV cooler on a custom PCB. This card joins the existing MSI GTX 770 with 2GB of memory in the company’s GPU lineup.
Specifications the new graphics card include a GK-104 based GTX 770 GPU with a base clock of 1137 MHz and a GPU Boost clockspeed of 1189 MHz. This compares to the 4GB Zotac GTX 770’s base and boost clockspeeds of 1059 MHz and 1098 MHz and to the reference NVIDIA GTX 770’s 1046 MHz base and 1085 MHz boost. In short, the upcoming MSI card is one of the fastest-clocked models with 4GB of memory. Unfortunately, that 4GB of GDDR5 does not come factory overclocked, and is instead left at the stock 7 GHz clockspeed.
Further, the MSI card is cooled by the company’s Twin Frozr IV cooler. This HSF features two 100mm fans that cool an aluminum fin stack. In turn, that fin stack attaches to the GPU block via five heatpipes. There is no backplate, but the card does have a reinforcing plate between the PCB and cooler (which also, likely, helps dissipate a small bit of the heat generated by the VRMs and RAM).
The card is essentially the same card as the existing 2GB version, which is not necessarily a bad thing. The model number on the 4GB card is N770 TF 4GD5/OC. MSI has not released pricing or availability, but expect it to be around $430 and up for grabs later this summer.

Not to be left out, Gigabyte is also releasing its own take on the GTX 760 Kepler GPU. This new GTX 760 Overclock Edition uses the company’s WindForce 3X cooler with “Triangle Cooling” technology. The card is model GV-N760OC-2GD and is available now from various retailers for around $260.
The GTX 760 OC Edition card has a GTX 760 GPU with a base clock of 1085 MHz and boost clock of 1150 MHz. Unfortunately, memory (2GB GDDR5) remains the same as stock cards at 6008 MHz.
The factory overclock on the GPU is among the highest options, but is not the highest clocked GTX 760 card. The reference card is clocked at 6008 MHz for the memory and a GPU base and boost clockspeed of 980 MHz and 1033 MHz respectively. The card supports the company’s OC Guru II overclocking utility as well, for adventurous enthusiasts wishing to see just how far they can push their particular cards on air cooling.
Gigabyte is using its WindForce 3X cooler for this overclocked model. The cooler features three angled fans and a custom fin stack with direct contact copper heat pipes to effectively transfer heat away from the GPU. Gigabyte uses two 8mm and four 6mm heatpipes to get heat into the fin array.
The Gigabyte GV-N760OC-2GD GTX 760 Overclock Edition is available now for $259.99.

MSI is joining the GTX 760 fray with its own version of NVIDIA's latest 700-series graphics cards called the N760 TF 2GD5/OC GTX 760. This midrange gaming card pairs an overclocked GTX 760 GPU with 2GB of GDDR5 memory and the company's Twin Frozr IV cooler.
Specifcations include a GTX 760 with base clock of 1085 MHz and a boost clock of 1150 MHz. It further has 2GB of GDDR5 memory, but it does not come factory overclocked (6008 MHz stock).
The cooler on the MSI GTX 760 is the Twin Frozr IV which features two 100mm fans, an aluminum heatsink with heapipes connecting the fin stack to the GPU base plate. The fans use MSI's "propeller blade" technology to increase airflow.
The N760 TF 2GD5/OC is not the fastest factory overclocked card, but it should be among the quietest with its two large fans that can spin at lower RPMs while still providing good cooling performance. It also opens up doors to users overclocking beyond the factory overclocked speeds, depending on the particular chip they get.
It is available now for $259.99 at various online retailers, including Newegg.

In addition to the monstrous GTX 780 Phantom GLH, Gainward is releasing a new Phantom graphics card based on NVIDIA’s new GTX 760 GPU.
This new Gainward GTX 760 Phantom graphics card shares many of the same features as its larger GTX 780-based sibling, just with lower specifications and pricing. The GTX 760 itself features 1,152 CUDA cores and a respectable factory overclock of 1072 MHz base and 1137 MHz boost. Gainward has even overclocked the 2GB of GDDR5 memory slightly to 6.2 GHz. For comparison, the reference NVIDIA GTX 760 comes clocked at 980 MHz base and 1033 MHz boost for the GPU and 6.0 GHz for the memory.
The factory overclock is not the only aspect that sets the Gainward model apart, however. This upcoming graphics card comes with a beefy power phase with DrMOS circuitry, support for the company’s EXPERTool overclocking utility, and a custom cooler. The HSF features an aluminum fin stack, two removable 80mm fans (to make dust removal easier), and four heat pipes connected to a copper base-plate that sits on top of the GPU. According to Gainward, its custom Phantom cooler is up to 6.5 dB quieter and 16-degrees Celsius cooler than the reference NVIDIA design.
Gainward has not released specifics, but expect the card to be available soon for somewhere around $270. Fortunately, reviews on this model are already starting to trickle out, and it looks promising.

There have been rumors of a new mid-range Kepler-based graphics card coming that will be next entry in the GTX 700-series. This new GPU is rumored to be called the GeForce GTX 760. If the specifications are true, the card will fit between the existing GTX 660 and GTX 660 Ti graphics cards as far as hardware specifications and pricing. While it will be under the GTX 700-series, it will not have the faster 7Gbps memory clockspeed of the other 700-series cards.
As far as specifications, Videocardz claims to have the final specifications list in a recent news post. The GTX 760 is rumored to be the latest graphics card to use NVIDIA's GK-104 "Kepler" GPU. The GTX 760 will have some units disabled for a GPU with 1,152 CUDA cores, 96 Texture Manipulation Units (TMUs), and 32 Raster Operations Processors (ROPs). The GPU supports NVIDIA's latest GPU Boost 2.0 technology which will automatically ratchet up the Boost clockspeed so long as temperature allows. It has a base clockspeed of 980 MHz and a boost clockspeed of 1,033 Mhz.
GTX 760 graphics cards will allegedly come in both 2GB and 4GB GDDR5 memory flavors. NVIDIA is clocking the memory at 6 Gbps (1502 MHz), which makes it the fist 700-series part to not take advantage of faster memory chips. However, there is a bit of saving grace as NVIDIA has moved to a 256-bit memory bus. This allows the card to still see a respectable bump in memory bandwidth of 192 GB/s on the GTX 760 versus the GTX 660/GTX 660 Ti's 144.2 GB/s bandwidth.
Compared to the existing mid-range 600-series cards, the GTX 760 has base and boost GPU clockspeeds equal to the GTX 660 (and faster than the GTX 660 TI). Memory clockspeed is also unchanged on the new card, though it has a wider memory bus. The GTX 760 has 192 more CUDA cores than the GTX 660, but 192 fewer CUDA cores versus the GTX 660 Ti. TMUs are also sit evenly between the two 600-series cards, but the GTX 760 does have 8 more ROPs enabled than both the 660 and 660 Ti.
Graphics cards with the upcoming GTX 760 GPU will be powered by two 6-pin PCI-E power connectors, and it has a 170W TDP. That power consumption puts the card between the 150W GTX 660 Ti and the higher-end 230W GTX 770. It appears that the card will not come with the high-end stock metallic cooler used in the other 700-series cards, though the various AIBs are likely to fit the GPU with their own custom aftermarket coolers. Video outputs on the cards will incluce DVI-I, DVI-D, HDMI, and DisplayPort.
The chart below compares the specifications between the GTX 660, GTX 660 Ti, GTX 770, and the rumored GTX 760.
|GTX 760||GTX 660||GTX 660 Ti||GTX 770|
|GPU Base||980 MHz||980 Mhz||915 Mhz||1046 Mhz|
|GPU Boost||1033 MHz||1033 MHz||980 Mhz||1085 MHz|
|Memory Clock||1502 MHz||1502 MHx||1502 Mhz||1752 Mhz|
|Bandwidth||192 GB/s||144.2 GB/s||144.2 GB/s||224 GB/s|
|TDP||170 W||140 W||150 W||230 W|
The card is supposedly going to be released on June 25th for around $300. It will compete with AMD's 7950 with boost graphics card. Further, the card will be an alternative to NVIDIA's own GTX 660 Ti and an upgrade for gamers still running GTX 560 cards with the company's older Fermi-based GPU.

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.
