PCB Design

Lacking any stickers or pictures of monsters and swords which you can see on other top-end products, the EVGA GeForce GTX 560 Ti 2Win has a modest appearance. The thick and slightly bent bars of the fan grid convey a feeling of solidity.

The graphics card is 293 millimeters long, exactly like the reference GeForce GTX 580 and somewhat shorter than the dual-processor Radeon HD 6990. It is 48 millimeters thick and 100 millimeters wide.

It is equipped with three dual-link DVI-I outputs and one mini-HDMI connector (which can be transformed into a full-size HDMI by means of the included adapter).

Thanks to this abundance of video outputs, the card supports Nvidia’s Surround and 3D Vision Surround technologies and can work with up to three monitors simultaneously. The regular GeForce GTX 580 can’t do that as it only supports up to two monitors. There is a vent grid in the card’s mounting bracket for exhausting the hot air out of the system case. Well, with the cooler design employed here, most of the hot air remains inside, anyway.

There are two 8-pin power connectors on the PCB. The power consumption of the EVGA GeForce GTX 560 Ti 2Win is not specified but, considering that of the regular GeForce GTX 560 Ti, it can hardly be below 320 watts. A 700-watt or better power supply is recommended for this graphics card.

 

There is even a MIO connector on the PCB, allowing you to join two such cards in SLI mode. You’ll have as many as four GPUs with a total of 1536 unified shader processors then!

The PCB is highly sophisticated and densely populated with components. The two GF114 processors are placed at 180 degrees relative to each other.

This positioning helped put all the components close to each other and keep the PCB as short as possible.

I couldn’t find any technical documentation about the EVGA GeForce GTX 560 Ti 2Win, but the number and position of its power system components suggest the 4+1 formula, like on the reference GeForce GTX 560 Ti, with 4 phases for the GPU and 1 phase for the graphics memory.

The two GPUs communicate with each other across an Nvidia NF200-SLI revision A3 chip manufactured on the 30th week of 2011.

The two 40nm GF114 chips are revision A1. They are identical and were both manufactured on the 38th week of 2011.

 

The GPUs have the standard GeForce GTX 560 Ti configuration with 384 unified shader processors, 56 texture-mapping units and 32 raster operators. But unlike the reference GeForce GTX 560 Ti with its 822/1644 MHz, the EVGA GeForce GTX 560 Ti 2Win clocks both its GPUs at 850/1700 MHz, which is 3.4% higher. This factory overclocking may be meant to make up for the imperfections of SLI technology which doesn’t always deliver a 100% performance boost. In 2D mode the clock rate of both GPUs is lowered to 51/101 MHz and their voltage is reduced from 1.05 to 0.95 volts.

According to the product specs, the graphics card is equipped with 2 gigabytes of memory. However, each of its GPUs can only access 1 gigabyte, so it would be more accurate to write “2x1 GB” into the specs. EVGA’s marketing department must have prevailed over the company’s engineers on this point. Well, I don’t think that’s a big problem, especially as the GeForce GTX 590 is specified to have 3 gigabytes of memory and the Radeon HD 6990, 4 gigabytes, for example. The memory chips are manufactured by Hynix and labeled as H5GQ1H24BFR ?2C.

They work at a voltage of 1.6 volts and have a rated frequency of 5500 MHz. The EVGA GeForce GTX 560 Ti 2Win has the same memory frequency as the reference GeForce GTX 560 Ti – 4008 MHz. It is lowered to 270 MHz in 2D applications. The memory bus is 2x256 bits wide.

Here is what the GPU-Z utility has to tell us about the EVGA GeForce GTX 560 Ti 2Win:

The older PCI Express 1.1 interface is indicated in the Bus Interface line. When you select the second card in the bottom dropdown menu, it shows PCI Express 2.0.
