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!
