Today at the GeForce LAN taking place in Shanghai, NVIDIA’s CEO Jen Hsun Huang unveiled the company’s upcoming dual-GPU powered, flagship graphics card, the GeForce GTX 690.
The GeForce GTX 690 will feature a pair of fully-functional GK104 “Kepler” GPUs. If you recall, the GK104 is the chip powering the excellent GeForce GTX 680, which debuted just last month. On the upcoming GeForce GTX 690, each of the GK104 GPUs will also be paired to its own 2GB of memory (4GB total) via a 256-bit interface, resulting in what is essentially GeForce GTX 680 SLI on a single card.
On GeForce GTX 680 cards, the GK104 GPU has a base clock speed of 1006MHz, with a Boost clock of 1058MHz. The GeForce GTX 690 will have a somewhat lower base GPU clock of 915MHz with a boost clock of 1019MHz. The memory clock on the GeForce GTX 690 will reportedly remain unchanged from the GTX 680 and run at an effective 6Gb/s. With those specifications, the GeForce GTX 690 will likely offer about 90% of the performance of a GeForce GTX 680 SLI setup, give or take a couple of percentage points depending on the application.
We'll also need a nuclear powered PSU just to boot up the system.
