The rumored GTX 760 graphics cards are still not available, but graphics enthusiasts do have a number of new factory overclocked GTX 780 cards with custom coolers to drool over. One such new GTX 780 card is the so-called GTX 780 Phantom GLH card from Gainward. This card is 2.5 slot monster that pairs the GTX 780 GPU with custom power phases and a giant block of aluminum and copper to support a healthy factory overclock.
This new Gainward Phanton GLH card pushes the GTX 780 GPU farther than the company's own GTX 780 Phantom. It has a base clock of 980MHz, boost clock of 1033 MHz, and slightly overclocked 6200 MHz memory. Of course, being based on NVIDIA's GTX 780 chip, the Phanton GLH features 2,304 CUDA cores and 192 Texture Units within 12 SMX units. The Phantom GLH's 3GB of overclocked GDDR5 memory affords the card 297.6 GB/s of memory bandwidth. Gainward claims that the new card is up to 19% faster than NVIDIA's reference GTX 780 graphics card.
To put that in perspective, the Gainward GTX 780 Phantom (non-GLH) is clocked at 902 MHz base and 954 MHz boost. Further, NVIDIA"s stock GTX 780 is has GPU clockspeeds of 863 MHz base, 900 MHz boost, and 6008 MHz for the memory. In other words, it is an impressive factory overclock, and I'm interested to see how much headroom is left for enthusiasts to push the chip further with the included cooler.
Other features of the upcoming Gainward GTX 780 Phanton GLH include an 8-phase PWM with DrMOS technology, a large aluminum fin stack with removable fans that is connected to a copper GPU block via five 8mm heatpipes, and an EXPERTmode option in the company's overclocking utility. Video outputs are the same as the reference design, with two DVI, one DisplayPort, and one HDMI port.
There is no word on pricing or when (and where) it will be available, but expect this beastly card to come at a premium. Although, as one of the fastest factory overclocked GTX 780 cards (soon to be) available, it may be worth it!
Computex 2013: Gigabyte Preparing Custom GTX Titan With WindForce 450W Cooler... Some Assembly Required

Back in April, Gigabyte showed off its new custom WindForce 450W GPU HSF, but did not name which specific high end graphics cards it would be used with. So far, NVIDIA's highest-end single GPU solution, the GTX Titan, has been off limits for GPU manufacturers as far as putting custom air coolers on the cards (NVIDIA has restricted designs to its reference cooler or factory installed water blocks).
It seems that Gigabyte has found a solution to the cooler restriction, however. The company will be selling a GTX TITAN with model number GV-NTITAN-6GDB later this year that will come with NVIDIA's reference cooler pre-installed along with a bundled WindForce 3X 450W cooler and instructions for switching out the coolers.
Gigabyte Is Showing Off the custom GTX Titan at Computex, as discovered by TechPowerUp.
Users that do take Gigabyte up on its offer to switch to the custom WindForce cooler will still be covered under the company's standard warranty policy, which is a good thing. The kit is likely to be more expensive than your standard TITAN though as Gigabyte is having to sell the card with two coolers and increased support costs. On the other hand, users could swap out the coolers and then sell the unused TITAN reference cooler to offset some of the cost of the kit.
Gigabyte is actually showing off the new graphics card with WindForce 3X 450W cooler at Computex this week. The dual slot WindForce cooler is said to keep a GTX 680 2°C and 23.3 dB quieter than the reference cooler when running the Furmark benchmark suite. The major benefit of the WindForce is having three large fans that can spin at lower RPMs to give you the same cooling performance as the reference NVIDIA design at a much lower noise volume rather than pure cooling performance. Should you be looking to push the TITAN to the extreme, a water block would be your best bet, but for many users i think the allure of a quieter air cooled TITAN may be enough for Gigabyte to snag a few adventurous enthusiasts willing to put up with assembling the new card themselves.
More information on the WindForce 3X 450W cooler can be found here.

First shown off at CES 2013, the EVGA Minibox is a small form factor chassis for Mini-ITX systems that can accommodate large graphics cards. EVGA has managed to enable users to pack a lot of hardware into this tiny form factor chassis. As a demonstration of the case's capabilities, the company showed off the latest version using a full system build with Core i7-4770K and GTX TITAN interals at Computex this week in Taipei.
The Minibox chassis itself is a dark brushed metal case with two USB 3.0 ports on the front IO and space for a slot loading optical drive. The MiniBox chassis further features a motherboard tray that supports Mini-ITX boards, two 2.5" SATA hard drive bays – and best of all – enough room to install full size GPUs. In order to support lengthy graphics cards, EVGA is including a small form factor 500W power supply that is mounted on the floor of the case..
HEXUS reporters spot the EVGA Minibox at Computex 2013. Look how small it is!
There will be at least two SKUs of the Minibox, depending on whether you want to go with air or water cooling. According to Bit-Tech.net, the air cooled version will use two 92mm fans in the top of the case and one 80mm fan for the bottom-mounted PSU. The water cooled SKU will be slightly larger but have enough room for a water cooling radiator (likely 240mm). Beyond that, details are scarce, but the air cooled version is said to be available as soon as next month with water cooled options becoming available later this year.
The Minibox looks to be one of the better Mini-ITX cases out there (although the price is still unknown), and should be popular among enthusiasts wanting a small box that does not sacrifice gaming potential.

EVGA GTX 780 Hydro Copper GPUs
While NVIDIA restricted partners from going with aftermarket coolers on the company's GTX TITAN graphics card, the recently released NVIDIA GTX 780 does not appear to have the same limits placed upon it. As such, many manufacturers will be releasing GTX 780 graphics cards with custom coolers. One such design that caught my attention was the Hydro Copper full cover waterblock from EVGA.
This new cooler will be used on at least two upcoming EVGA graphics cards, the GTX 780 and GTX 780 Classified. EVGA has not yet announced clockspeeds or pricing for the Classified edition, but the GTX 780 Hydro Copper will be a GTX 780 GPU clocked at 980 MHz base and 1033 MHz boost. The 3GB of GDDR5 memory is stock clocked at 6008 MHz, however. It uses a single 8-pin and a single 6-pin PCI-E power connector. This card is selling for around $799 at retailers such as Newegg.
The GTX 780 Classified Hydro Copper will have a factory overclocked GTX 780 GPU and 3GB of GDDR5 memory at 6008 MHz, but beyond that details are scarce. The 8+8-pin PCI-E power connectors do suggest a healthy overclock (or at least that users will be able to push the cards after they get them).
Both the GTX 780 and GTX 780 Classified Hydro Copper graphics cards feature two DL-DVI, one HDMI, and one DisplayPort video outputs.
The Hydro Copper cooler itself is the really interesting bit about these cards though. It is a single slot, full cover waterblock that will cool the entire graphics card (GPU, VRM, Memory, ect). It has two inlet/outlet ports that can be swapped around to accommodate SLI setups or other custom water tube routing. A configurable LED-backlit EVGA logo adorns the side of the card and can be controlled in software. A 0.25 x 0.35 pin matrix is used in the portion of the block above the GPU to increase the surface area and aid in cooling. Unfortunately, while the card and cooler are single slot, you will actually need two case PCI expansion slots due to the two DL-DVI connectors.
It looks like a neat card, and it should perform well. I'm looking forward to seeing reviews of the card and how the cooler holds up to overclocking. Buying an overclocked card with a pre-installed waterblock is not for everyone but having a water cooled GPU with a warranty will be worth it more than pairing a stock card with a custom block.

With 768 more CUDA Cores than the 680 but 384 less than the TITAN the 780 offers improvements over the previous generation and will be available for about $350 less than the TITAN. As you can see in [H]ard|OCP's testing it does outperform the 680 and 7970 but not by a huge margin which hurts the price to performance ratio and makes it more attractive for 680 owners to pick up a second card for SLI. AMD owners with previous generation cards and deep pockets might be tempted to pick up a pair of these cards as they show very good frame rating results in Ryan's review.
"NVIDIA's new GeForce GTX 780 video card has finally been unveiled. We review the GTX 780 with real world gaming with the most intense 3D games, including Metro: Last Light. If the GTX TITAN had you excited but was a bit out of your price range, the GTX 780 should hold your excitement while being a lot less expensive."

Missed the LIVE stream? You can catch the video reply of it below!
Hopefully by now you have read over our review of the new NVIDIA GeForce GTX 780 graphics card that launched this morning. Taking the GK110 GPU, cutting off some more cores, and setting a price point of $650 will definitely create some interesting discussion.
Join me today at 2pm ET / 11am PT as we discuss the GTX 780, our review and take your questions. You can leave them in the comments below, no registration required.
GK110 Gets a Lower Price Point
If you want to ask us some questions about the GTX 780 or our review, join us for a LIVE STREAM at 2pm EDT / 11am PDT on our LIVE page.
When NVIDIA released the GeForce GTX Titan in February there was a kind of collective gasp across the enthusiast base. Half of that intake of air was from people amazed at the performance they were seeing on a single GPU graphics cards powered by the GK110 chip. The other half was from people aghast of the $1000 price point that NVIDIA launched it at. The GTX Titan was the fastest single GPU card in the world, without any debate, but with it came a cost we hadn't seen in some time. Even with the debate between it, the GTX 690 and the HD 7990, the Titan was likely my favorite GPU, cost no concerns.
Today we see the extension of the GK110, by cutting it back some, and releasing a new card. The GeForce GTX 780 3GB is based on the same chip as the GTX Titan but with additional SMX units disabled, a lower CUDA core count and less memory. But as you'll soon see, the performance delta between it and the GTX 680 and Radeon HD 7970 GHz is pretty impressive. The $650 price tag though - maybe not.
We held a live stream the day this review launched at http://pcper.com/live. You can see the replay that goes over our benchmark results and thoughts on the GTX 780 below.
The GeForce GTX 780 - A Cut Down GK110
As I mentioned above, the GTX 780 is a pared-down GK110 GPU and for more information on that particular architecture change, you should really take a look at my original GTX Titan launch article from February. There is a lot more that is different on this part compared to GK104 than simple shader counts, but for gamers most of the focus will rest there.
The chip itself is a 7.1 billion mega-ton beast though a card with the GTX 780 label is actually utilizing much fewer than that. Below you will find a couple of block diagrams that represent the reduced functionality of the GTX 780 versus the GTX Titan:

Earlier this week, NVIDIA updated its Quadro line of workstation cards with new GPUs with GK104 “Kepler” cores. The updated line introduced four new Kepler cards, but the Quadro 6000 successor was notably absent from the NVIDIA announcement. If rumors hold true, professionals may get access to a K6000 Quadro card after all, and one that is powered by GK110 as well.
According to rumors around the Internet, NVIDIA has reserved its top-end Quadro slot for a GK110-based graphics card. Dubbed the K6000 (and in line with the existing Kepler Quadro cards), the high-end workstation card will feature 13 SMX units, 2,496 CUDA cores, 192 Texture Manipulation Units, 40 Raster Operations Pipeline units, and a 320-bit memory bus. The K6000 card will likely have 5GB of GDDR5 memory, like its Tesla K20 counterpart. Interestingly, this Quadro K6000 graphics card has one less SMX unit than NVIDIA’s Tesla K20X and even NVIDIA’s consumer-grade GTX Titan GPU. A comparison between the rumored K6000 card, the Quadro K5000 (GK104), and other existing GK110 cards is available in the table below. Also, note that the (rumored) K6000 specs put it more in like with the Tesla K20 than the K20X, but as it is the flagship Quadro card I felt it was still fair to compare it to the flagship Telsa and GeForce cards.
|Quadro K6000||Tesla K20X||GTX Titan||GK110 Full (Not available yet)||Quadro K5000|
|DP TFLOPS||~1.17 TFLOPS||1.31 TFLOPS||1.31 TFLOPS||~1.4 TFLOPS||.09 TFLOPS|
The Quadro cards are in an odd situation when it comes to double precision floating point performance. The Quadro K5000 which uses GK104 brings an abysmal 90 GFLOPS of double precision. The rumored GK110-powered Quadro K6000 brings double precision performance up to approximately 1 TFLOPS, which is quite the jump and shows that GK104 really was cut down to focus on gaming performance! Further, the card that the K6000 is replacing in name, the Quadro 6000 (no prefixed K), is based on NVIDIA’s previous-generation Fermi architecture and offers .5152 TFLOPS (515.2 GFLOPS) of double precision performance. On the plus side, users can expect around 3.5 TFLOPS of single precision horsepower, which is a substantial upgrade over Quadro 6000's 1.03 TFLOPS of single precision floating point. For comparison, the GK104-based Quadro K5000 offers 2.1 TFLOPS of single precision. Although it's no full GK110, it looks to be the Quadro card to beat for the intended usage.
Of course, Quadro is more about stable drivers, beefy memory, and single precision than double precision, but it would be nice to see the expensive Quadro workstation cards have the ability to pull double duty, as it were. NVIDIA’s Tesla line is where DP floating point is key. It is just a rather wide gap between the two lineups that the K6000 somewhat closes, fortunately. I would have really liked to see the K6000 have at least 14 SMX units, to match consumer Titan and the Tesla K20X, but rumors are not looking positive in that regard. Professionals should expect to see quite the premium with the K6000 versus the Titan, despite the hardware differences. It will likely be sold for around $3,000.
No word on availability, but the card will likely be released soon in order to complete the Kepler Quadro lineup update.

Before getting into the performance of the $1000 NVIDIA TITAN it is worth looking at the improvements NVIDIA has added to this GK110 beast. At 10.5" long it is a half inch longer than a 680 and a full 1.5" shorter than a 690, which allows it to fit in a wider variety of cases and the vastly improved thermals allow the usage of much smaller cases than other high end GPUs can manage without exotic cooling solutions. There is also a reduction in noise generated, to the point where SLI'd TITANs run quieter than some single card solutions, not to mention much faster. To take a look at just how much faster you can see [H]ard|OCP's results which you can compare to Ryan's results.
"NVIDIA is launching a TITAN today, literally, the new GeForce GTX TITAN video card is here, and we have a lot to talk about. We test single-GPU and 2-way SLI today, with more to follow later. We will find out if this TITAN of a video card really is worth it, and just who this video card is designed for. Be prepared to face the fastest single-GPU video card."

If you are reading this today, chances are you were here on Tuesday when we first launched our NVIDIA GeForce GTX TITAN features and preview story (accessible from the link above) and were hoping to find benchmarks then. You didn't, but you will now. I am here to show you that the TITAN is indeed the single fastest GPU on the market and MAY be the best graphics cards (single or dual GPU) on the market depending on what usage models you have. Some will argue, some will disagree, but we have an interesting argument to make about this $999 gaming beast.
A brief history of time...er, TITAN
In our previous article we talked all about TITAN's GK110-based GPU, the form factor, card design, GPU Boost 2.0 features and much more and I would highly press you all to read it before going forward. If you just want the cliff notes, I am going to copy and paste some of the most important details below.
From a pure specifications standpoint the GeForce GTX TITAN based on GK110 is a powerhouse. While the full GPU sports a total of 15 SMX units, TITAN will have 14 of them enabled for a total of 2688 shaders and 224 texture units. Clock speeds on TITAN are a bit lower than on GK104 with a base clock rate of 836 MHz and a Boost Clock of 876 MHz. As we will show you later in this article though the GPU Boost technology has been updated and changed quite a bit from what we first saw with the GTX 680.
The bump in the memory bus width is also key, being able to feed that many CUDA cores definitely required a boost from 256-bit to 384-bit, a 50% increase. Even better, the memory bus is still running at 6.0 GHz resulting in total memory bandwdith of 288.4 GB/s.
Speaking of memory - this card will ship with 6GB on-board. Yes, 6 GeeBees!! That is twice as much as AMD's Radeon HD 7970 and three times as much as NVIDIA's own GeForce GTX 680 card. This is without a doubt a nod to the super-computing capabilities of the GPU and the GPGPU functionality that NVIDIA is enabling with the double precision aspects of GK110.
