Asian tech site Expreview got its hands on a sample of the MSI GeForce GTX 660 HAWK (N660GTX HAWK). This model offers 15 percent higher clockspeeds than the reference model and is equipped with MSI's TwinFrozr IV cooling solution. The article is no longer available on Expreview's website, but TPU was quick enough to get the details.
The GeForce GTX 660 HAWK edition will have a 1100MHz core, 1176MHz boost, and 2GB GDDR5 memory at the reference clockspeed of 6000MHz. The PCB has 10-phase VRM power delivery with SSC chokes (low energy loss to noise) and IR DirectFETs. The card draws power from two 6-pin PCIe power connectors and seems to have voltage measurement points and a high-end voltage controller that enables software voltage control. MSI's GPU Reactor module is also included, it offers an extra set of tantalum capacitors for cleaner voltage delivery to the GPU.
Two physical EEPROM chips are found on the PCB for dual-BIOS functionality, one of the two has the factory overclocked frequency and voltage profile, while the other chip contains a fail-safe reference clockspeed profile.
Display outputs include dual-DVI, DisplayPort and HDMI. Pricing and availability is unknown.
