First Look: EVGA GTX660 SC
Packed with everything needed to get up and running, the EVGA GeForce GTX 660 2GB SuperClocked kit (02G-P4-2662-KR) includes: the factory-overclocked GeForce GTX 660 SC PCI-Express 3.0 video card, DVI-to-VGA adapter, 6-pin PCI-E to Molex 4-pin power adapter, and EVGA installation DVD with drivers and graphics software.
This review examines the factory-overclocked EVGA GeForce GTX 660 2GB SuperClocked video card, model 02G-P4-2662-KR. EVGA maintains the reference profile dimensions for their GTX 660 SC, which measures 1.5" tall (double-bay), 3.9" wide, and 9.5" long. The EVGA GeForce GTX 660 SC graphics card is designed to fit into nearly all mid-tower computer case enclosures with plenty of room to spare.
EVGA has adopted the effecient GTX 660 reference design, which operates quietly under normal use. A rear mounted 60mm (2.4") blower m otor fan rests slightly below the plastic fan shroud, allowing sufficient air to reach the intake whenever two or more video cards are combined in close-proximity SLI configurations.
Specified at 140W Thermal Design Power output the GeForce GTX 660 demands much less of the system's power supply unit, allowing NVIDIA to recommend a 450W PSU for single-card installations. GeForce GTX 660 requires power from a single six-pin PCI-E connections. With GeForce GTX 660 the power connection is relocated to the side of the video card, so to better fit into small PC enclosures.
As with past-generation GeForce GTX series graphics cards, the GTX 660 is capable of two-card SLI configurations. Because GeForce GTX 660 is PCI-Express 3.0 compliant device, the added bandwidth could potentially come into demand as future games and applications make use of these resources. Most games work well using medium settings with a single GeForce GTX 660 graphics card, but multi-card SLI configurations are perfect for gamers wanting to experience high-performance video games played at higher quality settings with some bells and whistles enabled.
The EVGA GTX 660 SC offers two simultaneously functional dual-link DVI (DVI-D and DVD-I ) connections, a full-size HDMI 1.4a output, and a DisplayPort 1.2 connection. Only one of these video cards is necessary to drive triple-display NVIDIA 3D-Vision Surround functionality, when using both DVI ports and either the HDMI or DP connection for third output. All of these video interfaces consume exhaust-vent real estate, but this has very little impact on cooling because the 28nm Kepler GPU generates less heat than past GeForce processors, and also because EVGA intentionally enlarged the vents to expel heated exhaust.
The memory subsystem has been tweaked on GeForce GTX 660, allowing the 2048MB GDDR5 video frame buffer to produce 144.2 GB/s total memory bandwidth at an impressive 6008 MHz data rate. Three memory controllers combine six GDDR5 ICs for a 192-bit memory lane, which moves data more efficiently than previous designs to yield a fill rate of 78.4 GigaTexels per second.
The exposed printed circuit board on the backside of the video card reveals an interesting discovery: GeForce GTX 660 uses a much smaller PCB than the profile suggests. Past GeForce products generally use a shroud to cover the entire length of the circuit board, but with GTX 660 the PCB measures only 6.75" of this 9.5" card, with a 2.5" extension to support the cooling fan.
