While MSI presented a shortened GeForce GTX 1070 Aero ITX video card, and ZOTAC showed a similar GeForce GTX 1070 Mini, KFA2 decided to focus on reducing the thickness of the cooler and announced a single-slot version – KFA2 GeForce GTX 1070 Katana. The novelty is cooled by a single radial fan. Since the width of the slot stub is also reduced, only three outputs remain – DVI, HDMI and DisplayPort. However, this will be enough for most users.
Despite the compactness of the cooler, the filling of the video card has remained the same. This is the same GP104 chip with 1.920 stream processors, as well as 8 GB of GDDR5 memory connected via a 256-bit bus. Even clock speeds have slightly increased compared to the version of Founders Edition. If NVIDIA recommends frequencies 1.506 and 1.683 MHz, the KFA2 GeForce GTX 1070 Katana runs at a base frequency of 1.518 MHz, and in Boost mode it accelerates to at least 1.708 MHz.
In practice, of course, the difference can be quite different, because the frequency directly depends on the cooling efficiency. Despite the fact that KFA2 did not provide detailed information about the cooler, we do not think that it will be inefficient. Thus, the real peak frequency will strongly depend on the specific benchmark.
In favor of the stability of clock frequencies, a modified printed circuit board with high-quality components also speaks. As an additional power supply, one 8-pin connector is used. The printed circuit board itself is much shorter than the entire graphics card.
The latter had to be extended to accommodate the elements of the cooler taking into account the cooling of both the chip itself and the power system. Directly on the GPU is a thick copper radiator base. And the fins of the radiator are made of copper, and not of aluminum, as it often happens. However, there are no heat pipes.
Unfortunately, KFA2 does not name the price, as well as the release date of KFA2 GeForce GTX 1070 Katana on the market.
