The Geforce GTX 770: specifications, reviews, overclocking

The focus of this article is new from the company Nvidia, the graphics card slot on the base of the 770 GTX. The potential buyer has the opportunity to get acquainted with the product better, learn technical characteristics of video card on the basis of the responses of the professionals to make their own conclusions before purchasing efficient video card for my computer. Review of available brands in the Russian market will allow the future owner to choose a manufacturer, of which today is not considered.

Little excursion

Many readers will agree that in the last few years, the policy of Nvidia company on the world market looks a little weird. Chipset GTX 770, which, judging by the marking, needs to have a capacity inherent in the AV class is a powerful device that can compete with more expensive high-end segment, albeit the previous generation. To verify this is quite simple: the graphics core, the appearance and the performance clearly hinted at legendary graphics cards GTX 680 and Titan.

As explained by the marketing Department of Nvidia, it's pretty simple. It turns out that the struggle is not for performance increase, but for the price niche that's important to take as opposed to the competitors from AMD. With the release of inexpensive video card HD 7970 GHz Edition of the Radeon, GTX 770 and became the counterpart in the niche 400. E. since the manufacturer didn't have the new chipsets in circulation was taken from the core GK 104. Rush output trends in the market led to the fact that the cooling system in a laboratory borrowed from the Nvidia Geforce Titan.

He Laughs best who laughs last

There is already something to think about owners of the top devices on the basis of the GTX 680. Because just recently they had for purchasing the top models to give a round sum (from 600. E.) for very powerful video card for demanding games. No one even suspected that Nvidia a year later, will represent the same video card that is only 30% cheaper – the GTX 770, the characteristics of which are better than the original. And what is common? This:

• Technical process 28 nanometers;
• Die area of 294 square millimeters;
• Of 3.54 billion transistors;
• 1536 stream processors;
• 128 texture units;
• 32 ROPS;
• Memory technology GDDR 5 2 GB on Board (and there are 4GB some manufacturers 770 GTX);
• Memory bus of 256 bits.

Changes have affected the clock frequency of the graphics core: the new 1046 MHz (GTX 680 1006 MHz only). Also overclocking yielded memory clock speed (6008 MHz and 7010 MHz). Of course, all this is reflected in throughput, which for novelty increased – 224, 4 GB/s (model 680 192 GB/s). About any honest manufacturer Nvidia against the buyers may not be out of the question – purely business.

Ancestry

A Massive radiator with a logo, which is backlit, certainly will delight the buyer. And when you consider that the backlight can be controlled using the normal drivers from Nvidia, the novelty does not look so bleak at first glance. It is worth noting that the 26-inch Board well by using the turbo fan, so no overheating can't be considered.

Due to the fact that the fee, according to the manufacturer, requires no additional power, it is recommended to use a PSU with a capacity of not less than 650 watt. In General, the power consumption of the video card Nvidia GTX 770 a lot of questions. The overclocking memory at 1000 MHz should definitely be accompanied by additional power, and improved cooling system. Apparently, the elimination of this problem is given to the industry giants that represent the video card on the market.

Got one!

The Gigabyte GTX 770, presented to the world community, equipped with a proprietary cooling system Windforce III. The manufacturer completely changed the design of the device than the fans. Replacement centrifugal fan from Nvidia at three axial was clearly more effective. This is evidenced not only in the media, and the evidence base on the basis of the test. Many, however, confused by the fact that the opening side of the cavity radiator has led to the fact that the hot air is output to the outside (outside the system unit) is returned into the case. I am glad that the technology company Gigabyte has taken care about the food system. Instead of the five-phase stabilizer Nvidia was installed in 8 phases.

Pleased with the manufacturer and specifications of the graphics card. Overclocking graphics core GTX 770 is 1137 MHz (Boost mode 1189 MHz). Judging by the reviews, the potential to disperse with such a great cooling system the video card is. Many owners were able to achieve stable operation at a frequency of 1200 MHz. Measurable increase in productivity has the opposite side of the coin – cooling system capacity emits a terrible howl, causing severe irritation to the user.

Kick the tail of the dragon

Nvidia GTX 770 from MSI is known to somehow not impressed users with its appearance. Standard cooling system, at first glance, have become boring to fans who always want something new from their favorite manufacturer. However, a detailed study of the radiator, the owner will notice the change. The radiator is literally riddled with fivecopper tubes that converge on the contact area of the heatsink with the GPU.

Pretty interesting technology implemented for the video card MSI GTX 770 overclocking. In the factory version, the accelerator has a nominal core clock and memory bus, as claimed by the manufacturer Nvidia. However, included with the graphics card there is a proprietary utility MSI Gaming App, which is able to independently overclock the graphics core. Most interesting is that the increase in frequency is inseparably connected with the temperature sensor on the chipset of the device. That is, in the game mode for those who have good air circulation in the system unit, will be able to achieve 1180 MHz, for example. And other users due to poor airflow “squeeze” from the core over 1100 MHz will not.

Criterion "price-quality»

Everyone's favorite Taiwanese manufacturer once again pleased its fans with an affordable price by launching the Asus GTX 770 DirectCU II. Hot new dual cooling system. In addition to the standard system of heat dissipation in the form of aluminum radiators with copper tubing, and two coolers from below the printed circuit Board is installed the hot-plate. For low-cost devices this cooling system is obviously a luxury, and therefore suspicious users.

Innovation ASUS not everyone will like. The manufacturer offers its own system of dispersal, which is held by utility and works without user intervention. In normal mode, the core operates at a frequency of 1058 MHz, but the slightest load indicator increases, stopping on a mark of 1110 MHz. Judging by the reviews, this system is not like users, because parallel to the load, increases heat dissipation, which is trying to eliminate two substandard cooler (hum 65 dB is clearly alluding to the cheap bearings).

Mistakes

Send technologists ASUS for retirement is too early. Apparently, after the avalanche of negative reviews about their product, serious Taiwanese brand has decided to make amends, and introduced the world to a silent Asus GTX 770 ROG POSEIDON. Graphics card features hybrid heat sink system, based on the liquid-air cooling. The owner is given the option to choose the mode of operation of the cooler: air, fluid, mixed mode. The cooling system covers the entire charge and has an led light red color.

Like its predecessor, the card is offered with the standard core frequency 1058 MHz, but overclocking adapter fully provided to the user. Judging by the reviews it professionals, the adapter works fine with GPU overclocking up to 1200 MHz. The nice thing for the user is high performance and complete silence video card. However, the price may be uncomfortable for some users, because the liquid system is not free, but it's peanuts compared to the real capabilities of the graphics card. Here you can also do a decent thing?

A Strange device for overklokerov

Fans and Thermaltake. The GTX 770 AMP brought to customers in all its black-and-yellow war paint. The representatives of the brand from the owners of devices never had issues. The cooling system at the highest level: quality fans, aluminum radiators, copper tube, good heat sink. Even special pads on the memory chips are present under the sinks-all of this indicates a serious approach to the products.

Decent cooling – the key to any acceleration. There is something to show off to competitors. Full-time core frequency set at around 1150 MHz! Auto-overclocking when the load increases has a limit to 1202 MHz. Memory frequency freely reaches 7200 MHz. And the most interesting is far not a limit.

You could call the video card under the brand name Panasonic product of the year, but there is one nuisance. If you continue to disperse its own forces over 1202 MHz, graphics card gets very hot and unstable. As practice shows, the problem in conventional capacitors that the manufacturer did not want to change to a solid-state container.

Phantom – the first after God

Yes! It is the GTX 770 Phantom Gainward brand in the factory performance is the efficiency leader in the world market among peers. Of course to achieve such results graphics helped the cooling system. Three turbocharged cooler installed on top of the heatsink, but directly in it (between the plates). At the request of the engineers, this system fared well on the previous model of the video card GTX 570 and, judging by the reviews, many users expect that the brand will surprise them with something more productive.

The nominal frequency of graphics of the poison is 1046 MHz, but in just a few seconds of branded utility Expert Tool capable of core 1250 MHz. And it is the nominal acceleration, and then everything depends on the desire of the owner and the temperature inside the system unit – if not brought to overheat, the potential for increasing productivity is. Burn graphics core will fail as at the level of BIOS installed in the razor, which when the core temperature of 100 degrees Celsius resets all settings to nominal (1046 MHz) and usingthe driver stops the operating system – “blue screen of death Windows”.

Eminence Grise

A Rather strange approach to the issue of the video card Nvidia GTX 770 from the EVGA company. Gray box, black disks with drivers and interface cables. Yes, and the video card is not particularly different from the regular instance manufacturer Nvidia. Only the company logo attached to the radiator shroud and the inscription “Superclocked” talking about accessories of the graphics card to EVGA. Technical characteristics of the adapter correspond to the declared data, Nvidia, and in the process of acceleration of the device produces an unpleasant hum. Users will appreciate just price – she's as weird as the video card (380. E.).

There on the market another representative of the company EVGA, made in the same grey style, but instead of the standard Nvidia cooler, the device is a proprietary cooling system, Active PFC with two turbo fans. Standard graphics core frequency is 1085 MHz and Boost of 1137 MHz. Pretty good performance, considering that the cooling system even at maximum is very quiet in comparison with other products on the chipset GTX 770. Reviews in the media on these two devices is greater than the questioners. What are these two products and how they got to the Russian market, still remains a mystery to many users.

Return of the legend

Judging by the reviews marketers who disappeared from the Russian market the company Point of View (PNY) is back. The manufacturer presents the product for overklokerov the video marking XLR8 OC Geforce GTX 770. Characteristics of the device will definitely attract the attention of many users. Basic core frequency is set at around 1150 MHz (1202 MHz Boost). The overclocking potential of the accelerator is small and, judging by the reviews, it is not encouraged by the manufacturer, so as to improve the performance of your forces dedicated a whole booklet that comes with the device. In short: any overclocking in the BIOS is fixed and immediately voids your warranty.

And without user intervention, the graphics card shows great performance in games. The stability of the device contributes to the cooling system consisting of an aluminum radiator and two silent coolers. Fans of World of Warcraft will love a gift from the manufacturer-Pandaren Monk, which will help to deal with the enemy in battle Pets. Other buyers will appreciate the affordable price (from 390. E.).

The Most beautiful video

If to carry out comparison of graphics cards in appearance, the leader in the category ‘Best design”, it would have been the device from the manufacturer ASUS-Geforce GTX 770 OC Edition. The naked eye can see teamwork of technicians, engineers and designers of the company. Under the black as pitch, a protective casing with three turbo fans hiding blackened radiators. Owners in their reviews have noted that after opening the package, could not admire the beauty of the graphics card. A real masterpiece!

The Manufacturer did not disappoint their buyers and have managed to combine beauty with high performance. As it turned out, the cooling system copes with its task by 100%, what will please all fans of overclocking. Great airflow, low noise – what else do you need for a wonderful time for your favorite game? The core operates at a frequency of 1085 MHz (Boost mode - 1137 MHz) and well dispersed to 1160 MHz.

In conclusion

With the advent of video card on base of GTX 770 gaming market is clearly confused. If earlier to run demanding games at high resolutions needed to purchase an adapter from a niche high-end, which costs around $ 1000. ie, now, five minutes to the public sector freely compete with top-end device. Clearly any changes in the market happen, it doesn't have to be that expensive device was the performance worse than the representative of cheap niche. On the other hand – this is a great chance for all gamers to get a decent and cheap video card that will cope with any stress in the coming years.
