PCB Design

The first thing you notice about the ASUS GTX 560 Ti 448 cores DirectCU II is how thick it is.

Indeed, the device is 58 millimeters thick and is going to block as many as three adjacent slots on your mainboard. The other dimensions are more conventional for this product class: 282 x 125 millimeters. The PCB is 267 millimeters long, the standard size for a GeForce GTX 560 Ti 448 cores card.

The card’s mounting bracket is huge, with not one but two vent grids for exhausting hot air from the cooler:

The video interfaces include two dual-link DVI-I ports, one HDMI port and one DisplayPort. The power and MIO connectors are standard as well.

 

It must be noted, however, that using this card in a SLI configuration may be problematic due to its unusual height.

The custom-designed PCB is taller than usual.

The 6+2 power system has six phases for the graphics core and two phases for the memory chips and power circuit components.

The SHE ASP0907 (Super Hybrid Engine) controller that manages the power supply of the GPU is in fact a rebranded uP6208.

There is a high-capacitance capacitor Proadlizer NEC/TOKIN on the reverse side of the PCB, right below the graphics processor. Such components are usually limited to hi-end products.

ASUS refers to its use of high-quality components with increased service life and durability as Super Alloy Power technology. This technology only covers the company’s top-end products although the GeForce GTX 560 Ti 448 cores can hardly be viewed as top-end. Well, it’s good that ASUS didn’t save on components but installed top-quality ones on this product, too.

The GF110-270-A1 chip of our sample of the card was manufactured in Taiwan on the 47th week of 2010.

We can remind you that the GeForce GTX 560 Ti 448 cores GPU has 448 unified shader processors, 56 texture-mapping units and 40 raster operators. Like on the reference card, the GPU clock rate in 3D mode is 737/1464 MHz at a rather low voltage of 0.975 volts. In 2D applications the graphics card drops its GPU frequencies to 51/102 MHz at a voltage of 0.913 volts.

The ASUS GTX 560 Ti 448 cores DirectCU II is equipped with 1280 megabytes of GDDR5 memory in 10 chips soldered on the face side of the PCB. The chips are manufactured by Samsung and labeled K4G10325FG-HC04.

The chips have a rated access time of 0.4 nanoseconds and a rated frequency of 5000 MHz. However, the ASUS card clocks its memory at 3800 MHz, in compliance with Nvidia’s GeForce GTX 560 Ti 448 cores specifications. The memory voltage is 1.5 volts; the bus is 320 bits wide. The memory clock rate is dropped to 270 MHz in 2D mode to save power.

We were lucky to have a GPU with a quality score of 87.3%:

Coupled with the high-quality components and fast memory chips, this is a promise of high overclocking potential. On the other hand, we guess the ASUS GTX 560 Ti 448 cores DirectCU II would be even more attractive for a larger target audience if the manufacturer had pre-overclocked it back at the factory.
