Posted by Berny Polanía | 1:23 PM | A short review for new graphic cards
The GeForce GTX 770 can best be described as a GeForce GTX 680 with a slight overclock (up 40 MHz to 1046 MHz) and a more notable boost (up 250 MHz to 1752 MHz). Introduced at a compelling $400, the 770 doesn't sport an exciting new GPU, but it's certainly a value leader compared to AMD's Radeon HD 7970 GHz Edition, which tends to cost $40 to $50 more.
At that price, the refreshed GK104-based board earns our recommendation.
In comparison, the GeForce GTX 780 is a de-tuned Titan with two of its SMXes disabled.
The GPU still wields 2304 CUDA cores, though. In the process of slimming GK110 down, Nvidia axes the chip's advanced FP64 capabilities, dropping back to 1/24 of the FP32 rate.
Gamers won't really care, though.
On the plus side, GeForce GTX 780 costs $350 less than Titan.
Even still, this $650 board is too expensive to garner any sort of value-oriented recommendation. It is an interesting option for builders looking to cram lots of performance into a small place with modest power use.
Nvidia is also getting more aggressive with the pricing on some of its existing products, particularly the GeForce GTX 670, which is down $20 to $350.
The GeForce GTX 680 dropped $30 to $420, but with GeForce GTX 770 selling for less, informed gamers won't be touching that one.
On a side note, GeForce GTX 690 and Titan are both tough to find, with single models going in and out of stock on Newegg.
As far as AMD's products go, we're seeing $10 drops on the Radeon HD 7970, 7950 Boost, 7870 2 GB, 7850 1 GB, and 7790.
Unfortunately, none of those adjustments take those models close enough to competing GeForce models.
In addition, we're surprised to see the average price of low end Radeon HD 6450, 6570, and 6670 DDR3 cards increase about $10.

Posted by Berny Polanía | 12:22 PM | Msi launches Gtx 650 power edition graphics card
Mainboard and graphics card maker Msi has announced the release of the Gtx 650 power edition graphics card.
According to the press release, the Msi Gtx 650 boasts a number of new features, such as the Msi power edition architecture, which provides overclocking support and transthermal cooling that allows better control over the temperature of the card.
Msi also claims that the Gpu is built with Msi Military Class III components, which would give it high quality and stability.
The card also allows users to install an extra fan to it for better cooling.
Msi''s Gtx 650 power edition is based on the Msi Power Edition architecture : support for Afterburner's Triple Overvoltage function, adjustable Gpu/ memory/ Pll voltages, completely liberating the graphic cards capacity, increasing overclockability by up to 27 percent.
The new Pwm design strengthens power capability 33 percent more than the reference board maintaining stability during overclocking.
Msi Gtx 650 Power Edition features the TransThermal cooling design that allows users to tailor the fan setup to the outside environment.
Double airflow mode uses a special mechanical design for attaching the fan to the existing heat sink module and increasing airflow to effectively reduce the Gpu temperature.
The external fan can also be placed next to the existing module in the dual fan mode.
The increased coverage improves cooling for the power supply module and components.
The Gtx 650 Power Edition also comes with Msi's proprietary dust removal technology.
The fan automatically runs in the reverse direction at start-up every time to remove dust and optimise cooling performance.
Msi’s Propeller Blade technology supposedly increases airflow by 20 percent compared to conventional fans and also expands the cooling area.
Effective temperature can be reduced by up to 9 degrees Celsius and noise levels can be reduced by up to 16.8dB.
The Msi Gtx 650 is made using Msi Military Class III materials.
A third-party laboratory simulated the user environment and conducted seven rigorous tests on compliance with the Mil-Std-810g standard.
Msi Gtx 650 power edition uses Tantalum Core Hi-c Cap and SFC can generate 30 percent more power. Solid state capacitors also have a service life of up to 10 years.
The choice of materials reflects Msi's commitment to its products.
Regardless of the overclocking or the gaming environment, MSI aims to provide consumers with a smooth and dependable environment.
The Gpu also has the latest drivers available on Nvidia’s website, which offers more optimisations for current-generation games.
The driver update comes highly recommended for the upcoming games Borderlands 2, and the expansion pack to World of Warcraft.

The bulk of products that Advanced Micro Devices will be shipping in 2.013 will be made using 28nm process technology, according to plans for the year 2.013 that were disclosed at the company's Financial Analyst Day.
AMD expects to roll-out three brand-new architectures next year : steamroller high-performance x86, Jaguar low-power x86 and Sea Islands family of graphics chips.
All product lineups that Amd promises to release next year will be substantially different from what is available today, hence, they will not be just product shrinks or refreshes.
28nm process technology alone is likely to allow Amd to boost performance and feature-set of its chips without increasing power consumption compared to existing solutions that are made using 32nm or 40nm fabrication processes.
Unfortunately, Amd did not disclose which of its 28nm chips will be made at Globalfoundries and which at Taiwan Semiconductor Manufacturing Company.
The new Steamroller x86 high-performance cores will improve performance by boosting efficiency of execution and will also include design elements from low-power architectures to reduce power consumption.
While it is unknown whether code-named Kaveri accelerated processing unit will turn the page for Amd in terms of x86 performance, the company hopes that further integration of x86 and stream processing architectures will boost overall user experience.
The forthcoming Jaguar low-power x86 architecture is expected to boost performance while trimming energy consumption, which will let Amd to better compete for tablets and similar devices.
Thanks to thin process technology, Amd's code-named Kabini and Temash APUs will also integrate input/output capabilities, which will greatly simplify system design.
Finally, the code-named Sea Islands graphics processors promise to bring "major GPU architecture enhancements" and skyrocket performance for both graphics and computing.
What is a bit surprising is that a high-performance FX-class x86 chip featuring Steamroller cores is absent from the 2.013 plan, but the Steamroller will still become available with the code-named Kaveri accelerated processing unit.
Apparently, Amd plans to continue selling its enthusiast-class FX chips code-named Vishera with Piledriver cores due to be introduced in 2.012 next year as well.

Amd has released a card that's just, well, better: the Amd Radeon Hd 7970 GHz Edition.
Since it released the original Radeon Hd 7970, in december last, the top single-GPU graphics card crown has slipped from its once mighty, and once mightily expensive, head.
Nvidia waited, holding its breath until March, when it released its top consumer spin of the new Kepler architecture, the Nvidia GeForce Gtx 680.
That came in slightly undercutting the Radeon card and just about pipping it to the benchmark crown in most of our tests.
Not just that but the Nvidia GTX 680 managed it with a far smaller and more efficient GPU.
To most of us that came as something of a surprise.
AMD traditionally had the reputation of releasing the more efficient GPUs of a generation with Nvidia usually the ones employing a brute force approach with a big, hot and powerful chip at the heart of its latest architecture.
That switch wasn't the only one of this latest generation either.
AMD's Graphics Core Next (GCN) architecture which makes up the Southern Island series of HD 7000 graphics cards was conceived with a view to creating a much more compute focused card.
Previous to this architecture Amd had focused on creating pure gaming cards with only a faint nod towards GPGPU processing.
Nvidia, on the other hand, chose performance per Watt for its consumer cards and sacrificed the GPGPU computing power that had been central to the Fermi architecture.
This cut-down GPU though was still a great gaming chip, as the Nvidia GeForce GTX 680 showed, leaving the Tesla team, with the GK110 K20, to the pro-graphics compute shizzle.
Still, it managed to best AMD's top card in most gaming benchmarks leaving it with the runners up prize.
The AMD Radeon HD 7970 GHz Edition is the Texan company's counter offer to gamers in light of the slight lead Nvidia managed with the GTX 680.
And to be fair, it's come up with quite an interesting proposal.
The salient point here though is that AMD has reclaimed the outright single-GPU performance crown of this generation.
Obviously that's discounting the twin-GPU toting Nvidia GTX 690, which has almost cheated its way to the top of the graphics card pile.
Though AMD had planned an assault on even that position, promising us the card once code-named as New Zealand.
You know, the place that has two Southern Islands making up the country.
Still, for whatever reason that card is off the table now with AMD focusing its efforts on bolstering the Tahiti GPU-sporting HD 7970 and making it the top single-GPU card around.
How has it managed this feature?
Well, the simple answer is overclocking.
We told you it was simple.
But this isn't quite the traditional card speed bump, or manufacturer-supported factory overclocked card you might normally expect.
Nothing has actually changed regarding the GPU itself.
AMD is still taking them from the same wafers, with the same designs, but it has taken the six months of learning that went into the subsequent Pitcairn and Cape Verde GPUs and applied it to the flagship chip.
Basically the GPU manufacturing process has matured and so has the technology and, most importantly, the software.
This has enabled AMD to get more top-end Tahiti cores out of the wafers and so is offering the AMD Radeon HD 7970 GHz Edition with a clockspeed of, you guessed it, 1GHz.
Though that's not strictly true.
In reality the clockspeed you're realistically going to get when gaming is actually 1.05GHz.
That extra 50MHz coming from something AMD is calling PowerTune with Boost.
The idea being similar in concept to Nvidia's GPU Boost, with some new hardware on the PCB monitoring the voltage and offering extra power, up to that 1.05GHz mark, when the thermal headroom allows.
In our testing that was all of the time, even with the standard reference cooler design.
Our reference AMD Radeon HD 7970 GHz Edition sat at a stable 1.05GHz for the entire time the GPU was pushed to 100% load.
The only other real addition of note to the card is the 3GB of GDDR5 graphics memory has been given a bit of a speed boost too.
The stock card has a 1,375MHz speed for its memory while the AMD Radeon HD 7970 GHz Edition comes with the VRAM running at a healthy 1,500MHz.
That's not all though as the type of memory used has been changed too.
This time it is using the faster 6Gbps VRAM over the 5.5Gbps chips it had been rocking, the same speedy memory the Nvidia GTX 680 is sporting then.
Thanks to AMD's faster 384 bit memory bus though the Radeon HD 7970 GHz Edition has a massive 288GB/s memory bandwidth compared with the 192GB/s of the top single-GPU Nvidia card.
That means at the higher end of the resolution spectrum the AMD card now seriously has the edge.
This video card is great because it has :
Lightning fast performance
Great compute performance
Top GPU on the block
Ant it is incredibly expensive
And has a great value with it
GPU - Tahiti XT
Process - 28nm
Clockspeed - 1,050MHz

Posted by Berny Polanía | 5:35 PM | Nvidia Dual GeForce Gtx 580 - Asus Mars II
Asus has never been a company to shy away from offering over-the-top, custom products that command a price premium.
Here's proof. Perhaps it’s because the company is large enough, and thus, has the resources to cater to virtually all market segments, big or small.
Or perhaps the top brass at Asus just likes inducing slack-jawed stares from PC enthusiasts. Whatever the reason, we hope they keep it up because testing this kind of stuff and showing it to you all is freakin’ fun.
A case-in-point is the Asus MARS II graphics card, which packs a full GeForce GTX 580, dual-GPU SLI configuration onto a single PCB.
A quick glance at this monolith should reveal to even the most casual PC users that the MARS II is no ordinary graphics card.
Heck, there isn’t a single thing about the Asus MARS II, from its specs, to its sheer size, and its huge price tag, that can be considered mainstream.
The MARS II is as over-the-top and as custom as they get and it’s also going to be a limited edition, with only 999 cards slated for production.
Luckily, one of those 999 cards (number 545 to be exact) found its way into the HH labs and we’re able to give you the full scoop on this beast.
Dissect the Asus MARS II and evaluate its performance, here’s a look at its packaging and accessory bundle.
For the most part, it’s pretty standard fair.
Included with the card are a couple of 8-pin PCI Express power adapters, a DVI-to-VGA adapter (for the insane user who uses a $1500 graphics card with an analog display), a driver and utility CD (with Asus' excellent GPU Tweak tool), a RoG case badge, a speed-setup guide, and an extended length SLI bridge.
In addition to the aforementioned items though, Asus also throws in a couple of noteworthy goodies.
First is an aluminum plate that’s individually laser-engraved and sequentially numbered to certify the card’s limited edition status.
Second, there are a couple of spacers that Asus calls “PCIe Sustainers”.
These spacers adhere to the bottom of the card and rest upon adjacent expansion slots to ensure the MARS II sits perfectly straight and upright in its slot.
Why would you need spacers to help keep the card sitting upright?
Because the thing weighs over 5lbs.
