First Look: GeForce GTX 650 Ti
In terms of appearance, the NVIDIA GeForce GTX 650 Ti is nothing like the other video cards in the GeForce GTX 600-series. Its squat 1.15" height requires two card slots for installation while allowing plenty of clearance, while the 5.65" long profile makes this is one of the smallest GTX's to come from NVIDIA in a very long time. In it's reference form, the GeForce GTX 650 Ti should easily fit most installations with room to spare. The majority of double-size video cards measure 1.5" tall, so with GTX 650 Ti being closer to the 0.75" single-slot height it's feasible we might see some NVIDIA partners creating such a design.
NVIDIA's GeForce GTX 650 Ti reference design operates quietly under full power operation thanks to a rear-mounted 75mm (2.95") fan that is positioned slightly above the plastic fan shroud. This allows sufficient air to reach the intake whenever two video cards are positioned in close-proximity; while SLI configurations aren't possible, another video card could be installed address PhysX demands.
Specified at 110W Thermal Design Power output the GeForce GTX 650 Ti demands much less of the system's power supply unit, allowing NVIDIA to recommend a 400W PSU for single-card installations. GeForce GTX 650 Ti requires power from a single six-pin PCI-E connection. With GeForce GTX 650 Ti the power connection is relocated at the rear of the video card, so at least 0.75" of additional clearance is necessary for the power connector.
GeForce GTX 650 Ti offers two simultaneously functional dual-link DVI (DVI-D and DVD-I ) connections, alongside a mini-HDMI 1.4a output (requires included adapter). Only one of these video cards is necessary to drive triple-display NVIDIA Surround functionality, when using both DVI ports with the HDMI connection for third output.
Since this is a dual-slot graphics card, there's a possibility some NVIDIA partners will use a larger I/O plate that offers full-size HDMI and possibly DisplayPort functionality. On other GTX-series cards these video interfaces would consume exhaust-vent real estate, but GTX 650 Ti exhausts internally (inside the case) so a larger plate would have little impact on cooling.
The memory subsystem on GeForce GTX 650 Ti delivers 1024MB GDDR5 video frame buffer to produce 86.4 GB/s total memory bandwidth at a noteworthy 5400 MHz data rate. Two memory controllers combine four GDDR5 ICs for a 128-bit memory lane, which moves data more efficiently than previous designs to yield a fill rate of 59.2 GigaTexels per second. GeForce GTX 650 Ti is backwards-compatible PCI-Express 3.0 compliant graphics device, although card's 128-bit memory interface makes it unlikely the added bandwidth will ever be fully saturated by the demands of this video card.
The card's exposed printed circuit board reveals indication that GTX 650 Ti could potentially support up to 2GB GDDR5 video memory, another option for daring card partners wanting to separate themselves from the competition. On some games with slow-moving yet extremely large worlds (World of Warcraft comes to mind) this could prove beneficial.
