GeForce GTX 590 Detalis Leaked via Slide

A “leaked” slide has revealed a few additional details about Nvidia’s upcoming dual-GPU GeForce GTX 590 card.

ZoomA supposed leaked slide has reared its face online, possibly one of many taken from a Nvidia partner presentation detailing Nvidia’s upcoming dual-GPU graphics card, the GeForce GTX 590. The leak arrives just after AMD launched its Radeon HD 6990 graphics card sporting dual Cayman GPUs, a dual-BIOS toggle switch, and a hefty $699 pricetag.

According to the slide, the GeForce GTX 590 will feature a 12 layer, 2-oz copper printed circuit board (PCB) designed with a 10-phase power layout. There’s also dual vapor chambers, 3 GB of GDDR5 memory (1.5 GB per GPU) and a PCIe dual x16 custom bridge chip. Oh and let’s not forget the two GF110 GPUs with a total 1024 (2 x 512) CUDA cores.

To round out Nvidia’s big 11-inch package, a removable cover will allow for easy cleaning. It also seems to reveal three DVI ports, possibly for 3D Vision Surround, and a dual-slot center-fan design that blows the air to the GPUs seated on the left and right.

The card will also require additional power through two 8-pin PCIe power connectors. If it’s anything like AMD’s monster Radeon HD 6990, the parent rig will need a 750W power supply at the least, 1200W for optimal performance. What’s surprising is that the card comes packed with 1 GB less memory than AMD’s offering, leading us to wonder if the slide may be mistaken.

Currently the Nvidia GeForce GTX 590 is rumored to be shipping on March 22, mere weeks away. We’re still waiting on something official to trickle through the Nvidia lines, so stay tuned.

China Expects to Compete with Intel, in 20 Years

China, which recently ascended to the top of the world’s supercomputer powers, said that, by the end of this year, it will not be using foreign processors for its future supercomputers anymore.

ZoomInstead, the country intends to rely on its own Loongson series of processing cores.

The upcoming Dawning 6000 supercomputer is expected to use 10,000 of these chips to achieve an estimated 1 Petaflop of processing performance. While it is a national priority to use its own processors, scientists admitted that it is difficult at this time to exploit the full potential of the chips as there aren’t programmers who can squeeze every bit of horsepower out of them.

China’s Tianhe-1A supercomputer, currently the world’s fastest supercomputer, uses a total of 186,368 cores and achieves a peak performance of 4.7 PFlops. The systems uses Intel Xeon X5670 CPUs as well as Nvidia Tesla GPUs.

China expects that it will take at least 10 years until the chips will be able to supply the domestic market. In 20 years, China wants to compete with companies such as Intel here in the U.S.

Nvidia CFO Resigns for ”Personal Reasons”

Nvidia CFO David White has stepped down and will be replaced by Karen Burns.

ZoomNvidia reports that chief financial officer (CFO) David White has resigned from the company for personal reasons, and will remain as a Nvidia employee through May 31, 2011.

Taking his place as interim CFO will be 43-year-old Karen Burns who currently serves as corporate controller and vice president of tax. Previously she served 10 years as head of Nvidia’s tax department, holding a “variety of titles.”

Before signing on with Nvidia, Burns served nine years in tax and audit roles with KPMG, a global public accounting firm, in its Atlanta, London and Silicon Valley practices. She holds bachelor’s and master’s of accounting degrees from Florida State University, Nvidia said.

As for 55-year-old David White, he joined Nvidia in February 2009 after leaving Sanmina-SCI Corp as the company’s CFO. Jen-Hsun Huang, Nvidia president and chief executive officer, said he was grateful for the counsel and leadership White provided over the last few years. But he also quickly pointed to Burns’ expertise in the same breath.

“Karen is a broadly respected veteran of Nvidia and knows our business well,” he said. “Her experience, her understanding of our business and her leadership will be a tremendous asset to us during this transition.”

A spokesperson for Nvidia said that the company had no further comments about White’s departure. However, Bloomberg reports that Nvidia stock dipped almost 6.5-percent in extended trading following the announcement. “Nvidia fell 54 cents to $17.66 at 4 p.m. New York time in Nasdaq Stock Market composite trading,” Bloomberg said.
