The Sapphire HD 7970 OC Edition sports two profiles, on set to defaults and one with a mild overclock of 1GHz on the GPU and effective memory of 5.8GHz but it really is the cooler which makes this card special.  The dual fans and extensive heatsinks allow for quieter and cooler operation than the reference design which can be more important to some than a huge overclock and since it is cooler you have a better chance of getting a higher manual overclock if you are so inclined.  Overclockers Club were very impressed with the card and even more impressed by Sapphire's decision to include an Active DisplayPort adapter.

"The Dual X cooler is really the bonus to this particular card; it is the real feature that sets it apart from not only other 7970s but also other high-end cards. Under full load it shows off its true colors as one of the best cooled cards on the market while remaining quiet (in a relative manner). With the fans at full it can dissipate quite a bit of heat away from the card to keep it cool and ready for more. It might dump a little more heat to the case at idle and run slightly "hotter" at idle, but it is much better than a constant vacuum cleaner noise coming from your case."

Tagged: galaxy, gtx 670 gc, factory overclocked

Galaxy went all out on the GTX 670 GC, using a full length custom PCB which allowed them to overclock the card by almost 100MHz right out of the box.  The base clock is 1006MHz as opposed to 915MHz and is higher than the stock boost speed of 980MHz, the GC's boost pushes all the way to 1085MHz.  Memory size remains unchanged at 2GB and 6GHz effective, but are shrouded in the custom cooler Gigabyte designed which allowed [H]ard|OCP to push the memory to 6.46GHz once overclocked.  In the tests the card could compete with the slightly more expensive GTX680 which makes this card one of the fastest cards you can get.

"GALAXY's new GeForce GTX 670 GC features a dual fan setup on a custom built PCB. GALAXY also tuned 670 GC with a strong 1006MHz overclock. We see how this compares to other video cards in its price range including a Radeon HD 7950 and GeForce GTX 580. Then we put the GALAXY GeForce GTX 670 head to head with a GeForce GTX 680."

There is only one thing worse than reading a review of an amazing GPU that you would love to buy if you could find it in stock; reading a review of several of these cards in SLI.  That's right, while you can't find a GTX680 in stock, [H]ard|OCP has a pair of overclocked Galaxy GTX 680 GC's which they are running in SLI, powering multiple monitors at a resolution of 5760 x 1200.  Not only that but they are getting good enough frame rates to play the games.  The only bad news is that the overclocked Galaxy card does not perform that much better than the stock card, however in [H]'s opinion the custom design is well worth the $30 premium.

How does Sapphire's overclocked HD7970 fare against the GTX680

Subject: Graphics Cards | April 13, 2012 - 01:17 PM |
Tagged: gtx680, hd7970, factory overclocked, sapphire

In one way, the Sapphire HD 7970 OC Edition wins this competition because of the simple fact that you can actually buy it.  However, we are also interested in the performance difference as you can occasionally find a GTX 680 for sale, so we need to know how the overclocked HD7970 performs.  Sapphire has placed two separate overclocked BIOSes on this card, one with a 950MHz core and 1425MHz memory as well as a more aggressively set one with a cores of 1000MHz and 1450MHz on the memory.  As it turned out [H]ard|OCP was never able to get the more aggressive BIOS to work, on the other hand when they manually overclocked it they hit 1150MHz core and 1860MHz for the memory at which speeds the card triumphed over the GTX 680 in every test.  Sapphire's card is ~$75 more than a GTX680 but remember, you can actually buy one.

"The Sapphire HD 7970 OC Edition video card has arrived and brings promise of low temperatures with Sapphires Dual-X Cooling System. It also features a Dual BIOS with both a passive and more aggressive profile. Will Sapphires highest end HD 7970 be able to keep up and compete with NVIDIA's flagship GeForce GTX 680?"

Announcing the MSI R7970 Lightning Graphics Card with Unlocked Digital Power Architecture

Subject: Graphics Cards | March 16, 2012 - 02:29 PM |
Tagged: MSI R7970 Lightning, msi, factory overclocked

MSI is taking full advantage of AMD's permission to wander away from the reference design with their brand new 7970 Lightning Edition.  Instead of putting a stable overclock on it and selling it at a mark up, they've completely redesigned the power architecture as well as replacing the cooler with one that is quieter and more effective.  From the proprietary "GPU Reactor" which increases the amount of current available for your GPU to a significantly higher maximum setting on Power Tune, this card is for the serious overclocker who is experienced with over-volting.

msi_lightning7970.png

Leading international graphics card and mainboard maker MSI today announced the release of the MSI R7970 Lightning, the new heir to the throne of Lightning graphics cards. Equipped with AMD's 28 nm Radeon HD 7970 GPU, the MSI R7970 Lightning features an all-new Unlocked Digital Power Architecture that incorporates an Unlocked BIOS, Digital PWM Controller, and Enhanced Power Design to boost overclocking potential to new heights and make overclocking easier than ever. In an industry first, the proprietary "GPU Reactor" power supply module reduces power supply noise and also boosts overclocking stability as well. To keep this beast cool, the MSI R7970 Lightning utilizes the latest Twin Frozr IV Thermal Design equipped with Dust Removal Technology. The dual 10 cm fans with Propeller Blade Technology generate massive airflow for fast heat dissipation while remaining whisper silent. The two form-in-one heat sinks improve cooling for memory and the power supply module as well ensure structural integrity. The R7970 Lightning uses Military Class III components which have passed rigorous third-party testing to meet MIL-STD-810G standards, guaranteeing the card's stability and reliability under actual use conditions. Moreover, the "3X3 OC Kits" are designed to simplify overclocking, which makes it easier than ever for enthusiasts to fine-tune the performance of their graphics cards. For both professional users and gaming enthusiasts alike, the R7970 Lightning's ability to simultaneously run 6 displays makes it the natural choice!

Unlocked Digital Power Provides Record-Breaking Potential
The R7970 Lightning boasts an all-new Unlocked Digital Power architecture that provides record breaking potential. The key components involved include the Unlocked BIOS, digital PWM chipset, and an improved power supply design. Unlocked BIOS removes CCC overclocking limits, Power Tune limit is increased by 180%, and OCP limits are relaxed to completely unleash the graphics card's overclocking potential. The digital power supply signal provides voltage signals that are more stable and accurate than conventional analog designs, meaning the voltage can be adjusted more quickly and precisely during overclocking. The improved power supply design provides double the power of the reference board and consists of 17 power supply parameters, dual 8-pin power supply connectors, and the Lightning Power Layer (LPL) design. For true overclocking enthusiasts, the R7970 Lightning with Unlocked Digital Power is simply a dream come true!

GPU Reactor for the Ultimate Power Core
The MSI R7970 Lightning implements the innovative "GPU Reactor" power supply module which, when installed on the back of the GPU, increases current volume by 88%, reduces power supply noise by 13%, and improves overall overclocking stability. MSI GPU Reactor is easy to install and has built in safety features that make it easy even for ordinary users to install and remove.

Extreme Cooling Design for Better Cooling and Structural Strength
The MSI R7970 Lightning incorporates the next-generation Twin Frozr IV Thermal Design. The striking design of the new Twin Frozr IV comes from the two large 10cm PWM fans with Propeller Blade Technology that cool the advanced cooling body of the Twin Frozr IV. Under the aluminum Twin Frozr IV body, you can find a high density fin grid array that provides heat dissipating area that is fed by heat-pipes featuring MSI's SuperPipe technology. MSI has also incorporated its exclusive Dust Removal Technology. Fans are running in reverse for 30 seconds after booting to remove dust from the heat sinks and keep the graphics card's cooling performance running at optimum levels. The R7970 Lightning also boasts two form-in-one heat sinks. One heat sink is located on the front of the graphics card to cool the memory and power supply modules, while the second heat sink on the back of the card helps to protect and reinforce the card structure. This extreme cooling design provides the R7970 Lightning with the best cooling performance and the most reliable structure.

Premium Materials and User-friendly Overclocking Design
MSI has always led the industry thanks to its unyielding commitment to product stability and quality and made sure that the R7970 Lightning was equipped with Military Class III components certified to MIL-STD-810G military standards in seven different categories by a third-party laboratory. Be it tantalum core Hi-c CAP around the graphics card, the CopperMOS cooling design, the form-in-one Golden SSC, or as the card's moisture/rust-proof Dark Solid CAP, all work together to provide the MSI R7970 Lightning with the best possible stability.

For overclocking enthusiasts, MSI has developed the 3X3 OC Kits: V-Check Points enable GPU, Memory and VDDCI voltage to be monitored while Triple Overvoltage and Triple Temperature Sensor enable overclockers to quickly fine-tune and track the performance of their graphics card using enthusiasts favorite Afterburner overclocking software. The 4 Mini DisplayPorts and 2 DVI ports on the R7970 Lightning enable AMD Eyefinity technology to drive 6 screen output with just one card, providing just the kind of performance industry professionals and gaming enthusiasts need.

Tagged: sapphire, hd 7950, hd 7950 OC, factory overclocked, cape verde, amd

There are a lot of custom Cape Verde boards to chose from, with varying clock speeds and custom coolers which is great for those who like something unique out of the box.  X-bit Labs received an overclocked HD7950 board from Sapphire which sports both a 100MHz overclock on the GPU and a custom low noise cooler.  The back of the card is fairly normal, with a dual-link DVI-I port, one HDMI 1.4a connector and two DisplayPort 1.2 ports available.  Overclocking potential on the card was impressive, with a final 1.15 volts allowing stable performance at 1100MHz GPU and 7360 MHz effective on the memory and a temperature of 74C at full load thanks to the cooler.  Even better is the fact that the cooler operates relatively quietly even at that high overclock.

Meet the new mid-range; AMD's HD7770 and HD7750

Subject: Graphics Cards | February 15, 2012 - 02:33 PM |
Tagged: xfx, southern islands, hd 7770, hd 7750, cape verde, amd, radeon, factory overclocked

The days of the HD 6870 are numbered as today we see the arrival of the new sub-$200 GPUs from AMD, the HD7770 and HD7750.  The stock HD 7770 run at 1GHz with 640 stream processors, 40 texture units and 16 ROPs and the 1GB of memory rides on a 128-bit bus at 4.5GHz.  The stock HD7750 has a slower core, running at 800MHz and a lower stream processor count of 512 as well as only 32 Texture units, with the memory subsystem unchanged from the HD7770.

Those who were disappointed by the lack of custom coolers and factory overclocks at the release of the HD 7970 will be happy to see the variety of HD7700 series cards.  For instance [H]ard|OCP reviewed the XFX R7770 Black Edition Super Overclocked which has a custom cooler, a 120MHz overclock on the core and a 300Mhz on the memory, effectively 5.2GHz.  [H] proved that there is more memory headroom available in this card, adding another 1.1GHz without needing to adjust the voltage.  For those who are willing to risk upping the power there might be even more speed possible from this card. 

You can also catch Ryan's review of the same card as well as an MSI version and a stock HD 7750.

Gigabyte's non-standard HD 7970

Subject: Graphics Cards | February 14, 2012 - 01:54 PM |
Tagged: hd7970, gigabyte, factory overclocked

The most noticeable difference on Gigabyte's HD 7970 is the custom cooler, with three fans and a nice shroud, which should keep this card cool and quiet.  This is a good thing as the card sports a moderate overclock of 1000MHz on the core though the memory remains at stock speeds.  It doesn't need to stay at that speed however, [H]ard|OCP got the card up to 1305MHz for the core and 1605MHz for the memory, 6.42GHz effective.  That overclock is quite noticeable in games over both the GTX580 and the stock HD7970 though the performance comes at a price as the card pulls over 100W more than the stock card at full load.  For those drooling over the performance remember that these cards are intended to power multiple screens; [H] tested at 2560 x 1600 and if your setup is not of that resolution or higher you are tossing away money at a product you will not be using to its full potential.
