Closer Look (Continued)


The shroud and cooler

The shroud can be easily removed to reveal the heatsink and fan attached to a metal bracket secured to the card’s PCB. Underneath, it’s a very attractive card and oozes quality for a mid-range graphics card.


The metal bracket and bare PCB

Beneath the cooler, the blue PCB is very striking. The components are laid out similarly to the reference GTX460 with the GPU placed in the middle and surrounded by eight memory modules. The power circuitry is to the right with the voltage controller situated close by. Again, the PCB appears very bare. It is possible that Nvidia employed a larger PCB to accommodate a larger cooler. Below the cooler bracket are thermal pads for additional memory and circuitry cooling.


The GF114 GPU

Upon removing the heatsink, the GPU core and memory chips are left exposed. The integrated heat spreader on the die is rather large but helps create a larger surface area for heat dissipation. Looking closely, it's clear that the chip is indeed a GF114 core. The core is surrounded by eight 128MB memory modules to give a total of 1024MB.


The Samsung K4G10325FE-HC04 modules

The memory modules are the same found on other Nvidia cards. These are manufactured by Samsung and sport the model number: K4G10325FE-HC04. The GDDR5 memory is rated at 0.50ns for an effective 5.0Gbps. The memory on the Inno3D GTX560 comes clocked at an impressive 4300MHz from the default 4000MHz, the limit of what they are rated at.


The power circuitry

The reference GTX560 sports a 4 phase power design as indicated by the 4 chokes near the end of the card. The MOSFETS are next to each choke. Surprisingly, the circuitry is as robust as that found on the GTX570, so given a more efficient core, we can expect tremendous overclocking headroom. As such, Inno3D themselves have already boosted the core speed to 950MHz.


The voltage controller

The card uses an ON Semiconductor NCP5380 on-board voltage regulator and voltage tweaking is supported using MSI Afterburner.


The heatsink

The heatsink installed onto the card is very impressive for a reference design. It uses three heat pipes and a radial fin design reminiscent of old Zalman heatsinks. The fan uses a four pin connector for PWM functionality to vary fan speed based on temperature.
