Gigabyte recently introduced a new breed of Black Edition motherboards that must survive a week-long torture test before leaving the factory. This stress test relies heavily on Litecoin mining, and it isn't just for motherboards. Graphics cards are also getting the Black Edition treatment. The first among them has popped up on Gigabyte's UK site; it's called the GV-N75TWF2BK-2GI, which means GeForce GTX 750 Ti Black Edition in plain English.
Unfortunately, the official product page appears to be somewhat unfinished. The Black Edition primer references motherboards instead of graphics cards, for example, and there's some disagreement on clock speeds. The overview says the Maxwell-based GM107 GPU is clocked at 1163MHz base and 1242MHz Boost, while the spec sheet claims 1033MHz base and 1111MHz Boost. (The 750 Ti runs at 1020/1085MHz by default.)
We've asked Gigabyte for clarification, but my money's on the higher-clocked config. The Black Edition's model name is a close match for the GV-N75TWF2OC-2GI, which runs at 1215/1294MHz. Either way, you get 2GB of RAM at 5.4 GT/s.
Unlike the slot-powered GeForce 750 Ti reference card we tested in February, the Black Edition card requires auxiliary power from a six-pin PCIe connector. Gigabyte's dual-slot, dual-fan cooler also extends well beyond the boundaries of the short circuit board. The heatsink stretches the card length to 8", and the heatpipe poking out the top pushes the height to 5.7". Keep that in mind if you want to stuff one of these things inside a small-form-factor case.
Amazon already has the Black Edition 750 Ti listed online, but there's no price tag attached, and we don't yet know what sort of premium Gigabyte intends to charge for Black Edition graphics cards. For reference, Gigabyte's similarly clocked 750 Ti OC card is selling for $169.99 before a $20 mail-in-rebate.
Update: Gigabyte has confirmed the clock speeds listed on the overview page. The GeForce GTX 750 Ti Black Edition has 1163MHz base and 1242MHz Boost frequencies.
