On the other hand, thanks to the fan working both ways, the GPUs are going to have about the same temperature, which may be beneficial for overclocking. Some of the hot air remains inside the system case, which seems to be the only downside of this cooler design. The air from that fan goes through the slim heatsink fins and gets exhausted through the vent grid in the mounting bracket as well as through the opening in the other side of the casing. The power system components and memory chips are cooled by a metallic plate that carries a 9-blade 83mm impeller with PWM-based regulation. Here’s how the cooling system deployed on the GeForce GTX 690 is supposed to work.The GPUs have nickel-plated aluminum heatsinks with copper base designed as a vapor chamber.
GPU-Z 0.6.1, the latest version available as of our writing this, knows the GeForce GTX 690 well enough. The card’s memory clock rate is 6008 MHz in 3D mode (the same as on the GTX 680) and 648 MHz in 2D mode. There are 2 gigabytes of memory per each GPU. FCBGA-packaged chips from Hynix Semiconductor labeled H5GQ2H24MFR R0C. We couldn’t read the markings on the GDDR5 memory chips of our card but we suspect the GeForce GTX 690 to use the same memory as the GeForce GTX 680, i.e. The GPU frequency is dropped to 324 MHz in 2D mode. The boost clock rate is 1019 MHz, which is only 3.9% lower than the boost clock rate of the GeForce GTX 680. It is 915 MHz in 3D applications or 91 MHz lower compared to the GTX 680. However, the base GPU clock rate is reduced in comparison with the GeForce GTX 680. The card has a total of 3072 unified shader processors, 256 texture-mapping units, and 64 raster operators. If you’ve examined the specs, you must have noticed that the GeForce GTX 690 comes with full-featured Kepler GPUs that are not cut down in any way. The 10-layer PCB is populated by two GK104 Kepler chips, two 2GB sets of GDDR5 memory, a switch chip and power circuitry.The power system contains 10 phases.The two GPUs communicate via a PLX Technology PEX8747 chip that supports up to 48 PCI Express lanes. A 650-watt or higher PSU is recommended for a computer with a GeForce GTX 690 inside. The GeForce GTX 690 is specified to have a peak power draw of 300 watts and a typical power draw of 263 watts. The GeForce GTX 690 is equipped with one SLI connector, so you can build a multi-GPU configuration with two such cards and a total of four top-end GPUs!Īt the back of the card we can see two 8-pin power connectors. Thanks to this configuration of video interfaces, you can connect as many as four HD monitors to a single GeForce GTX 690.There’s an opening in the opposite side of the casing through which you can see the fins of one of the GPU heatsinks.Some of the hot air is exhausted through that opening into the system case. You can also find three dual-link DVI-I connectors and one mini-DisplayPort here. We can note the lack of vent holes.There is a vent grid in the card’s mounting bracket, though. You’ll see it again in this review shortly. There are highlighted letters “GEFORCE GTX” on one edge of the card. That’s okay because the exposed PCB is going to be cooled better than if it were completely sealed within a casing. Indeed, the photo can’t convey the pleasure you feel while holding this card in your hands.

Instead of trivial plastic or ordinary metal, the casing is made of aluminum coated with trivalent chromium and has a black magnesium-alloy insert around the fan and two polycarbonate windows through which you can see the GPU heatsinks. The face side of the PCB, which is 280 millimeters long, is covered by the cooler’s casing. Indeed, this graphics card betrays the developer’s attention to every detail. Nvidia touts its GeForce GTX 690 as the acme of computing technologies, comparing it to the supercar Ferrari F12 Berlinetta and the audiophile system B&W Nautilus. Once again, the recommended price of the new card is $999. GeForce GTX 690 will be available from many brands such as ASUS, EVGA, Gainward, Galaxy, Gigabyte, Inno3D, MSI, Palit and Zotac and these makers are going to put everything necessary into the box (we’re not sure about the prybar, though). There are no accessories, not even power cables, but that’s just a prelease sample for testing purposes. The two thick sheets of foam rubber securely fix the masterpiece of engineering thought, the object of desire for millions of common gamers, the No.1 item on the shopping list of a few thousand wealthy enthusiasts – the GeForce GTX 690 graphics card.
