Nvidia Quadro K5000 coming to the Mac Pro

Nvidia announced today that its upcoming Quadro K5000 will be available for use in Apple's Mac Pro systems. The new GPU is Nvidia's flagship graphics process based on its new Kepler architecture, which will have 4GB of video RAM and be about two times faster than the current Quadro 4000 GPU based on the current Fermi architecture.

Recently Engadget had a look at the new GPU running in a Mac Pro system, and found impressive performance from it when streaming HD video and adding effects in real time. Some programs like Adobe After Effects can utilize more than … Read more

Mac Pro users experiencing random log-outs in Mountain Lion

A small number of Mac Pro owners who have upgraded to Mountain Lion are reporting an issue where the system seems to randomly log out, quitting all applications without any warnings and returning to the log-in screen.

While this may appear as if the system has restarted or even performed a standard log-out, the system is in fact experiencing a crash in a critical process called the Window Server that supports the current log-in session by managing the drawing and representation of windows on the screen. Crash logs that affected users have revealed show that the problem is rooted in … Read more

Microsoft explains how Windows 8 smokes Windows 7

Microsoft spelled out acceleration improvements in Windows 8, in a blog post Monday. Needless to say, Microsoft says the overall experience is a lot snappier.

The latest Building Windows 8 entry, penned by Rob Copeland, the group program manager at Microsoft's graphics team, is titled Hardware accelerating everything: Windows 8 graphics.

Some context is first provided at the top in order to illustrate how Window 8 "builds on the well-established foundations of DirectX graphics" in Windows 7.

In Windows 7, we expanded the capabilities of DirectX to provide a common hardware-accelerated graphics platform for a broader range … Read more

Intel not joining graphics chip alliance

Intel will not join a chip-related alliance aimed at making it easier for software developers to take advantage of the compute power locked up in graphics silicon.

Advanced Micro Devices, ARM, Imagination Technologies, MediaTek Inc., and Texas Instruments announced the Heterogeneous System Architecture (HSA) Foundation on Tuesday.

Here's how Lisa Su, an AMD senior vice president, described it in a phone interview with CNET.

"The point is, even if you put a really powerful CPU next to a really powerful GPU, if these [chips] don't interact and the applications don't know when it's better to … Read more

Nvidia accelerates gaming in the cloud

Nvidia announced graphics-chip based cloud tech today, claiming to deliver fast gaming to almost any device.

"GeForce GRID represents a massive disruption in how games are delivered and played," said Phil Eisler, general manager of cloud gaming at Nvidia, in a statement.

The trick is to power the games remotely with brawny servers that tap into Nvidia's new Kepler graphics processing units (GPUs).

Each Kepler chip has 3,072 Nvidia "CUDA" processor cores and packs 4.7 teraflops (trillion floating point operations per second) of 3D shader performance. Shaders are instrumental in rendering realistic effects … Read more

What kind of heat is the future 15-inch MacBook packing?

The upcoming 15-inch MacBook is expected to pack plenty of brawny silicon despite its svelte dimensions. With speculation on its specs rife, it's time to take a crack at what may be under the hood.

Graphics: Apple's redesigned MacBook may return to Nvidia graphics, as reported by 9to5Mac.

That would be the first time Apple has opted for Nvidia in a MacBook since earlier versions of the Air. Current 15-inch MacBook Pros have ATI graphics chips, and MacBook Airs sport integrated Intel graphics processing units (GPUs).

Note that a report back in March said Nvidia wouldn't make … Read more

AMD adds new mobile graphics chips: Radeon 7700, 7800, 7900

With Intel's new Ivy Bridge third-generation Core i-series CPUs dominating the PC component discussion this week (or really, the last several months), it would be easy to miss today's announcement from AMD about new GPU parts.

AMD's Radeon graphics line, formerly branded under the ATI name, is found in many high-end laptops, including HP's Envy line and Apple's MacBook Pro. The current HD7000 series is now being expanded to include the HD7700M, 7800M, and 7900M.

AMD promises several new features from these updated GPUs, including smoother switching between integrated and discrete graphics. Rival Nvidia has … Read more

Nvidia to debut GTX 690 GPU soon?

Graphics processor giant Nvidia has posted on Facebook a shadowy image of its "eye" logo on a graphics card processor (or other related chip) with the decree: "It's coming."

A stream of rumors began to flow after the cryptic Facebook posting by Nvidia, but PC enthusiast blog SweClockers wrote that several independent, reputable sources say the upcoming Nvidia announcement coincides with the anticipated launch of the Nvidia GeForce GTX 690, a dual-core graphics card that employs two very powerful GK104 graphics processing units.

The Swedish blog mentions that the GTX 690 release falls between April 30 and May 5, a period directly after the launch of Intel's Ivy Bridge chips that emphasize graphics and multimedia processing.

Nvidia: Smartphone graphics to best Xbox 360 by 2014

For now, mobile devices still can't match game consoles in graphics quality. Nvidia thinks that could change, and soon.

The company last night sent over a slide to enthusiast site Anandtech charting the graphics performance progress across the console, PC, and mobile markets. And although PCs will continue to stand above the fray, Nvidia believes that by 2014, mobile system-on-a-chip (SoC) GPUs will offer better graphics performance than does the Xbox 360. In 2013, the mobile chips could match Microsoft's console.

Nvidia's findings -- which, while listed on the slide as "console," only examined the … Read more
