Is the CPU dead or alive? Nvidia says a little of both

Nvidia's hostility toward Intel is on a high boil these days. In its latest dig against the central processing unit (CPU) and the company that makes the lion's share of CPUs, an Nvidia VP said in a private missive that the CPU is dead and it has "run out of steam."

But wait. That's not what Nvidia really thinks. The message cited by the The Inquirer is "not a public statement," said Brian Burke, an Nvidia spokesperson. "The views in (Roy Tayler's) e-mail do not mirror the views of Nvidia." (… Read more

Buzz Out Loud 700: Merger-mania!

Yahoo and Microsoft bring Google, AOL, and News Corp. into the ring for a pretty awesome merger-mania that we sincerely hope involves the gratuitous use of Spandex. Sunday, Sunday, Sunday on Pay-per-view! That darned RSA conference continues to scare the sneezes out of us by demonstrating how taking down a national power grid is trivially easy. (Insert nervous giggle here.) We guess it's good to know? Listen now: Download today's podcast EPISODE 667

First Atom benchmarks appear online

Atom, Intel's new processor family for small devices, has barely been announced, and yet already one German tech site has posted some benchmark results. ComputerBase is reporting that its 1.6GHz Atom chip fell slightly behind a 900MHz Celeron M chip on the Super PI benchmark.

That may not be enough to run an actual laptop (the 900MHz Celeron is best known as the chip inside the stripped-down Eee PC) but it should be enough for the mobile Internet devices that are destined to incorporate the new platform. Besides, energy efficiency, not performance, is the Atom's main selling … Read more

Power Downloader monitors his memory

When Power Downloader is hard at work in the Powerlair he often has several programs running simultaneously. Though he has plenty of RAM in his super system, Power likes to keep track of memory usage to see what's taking up the most space. It also helps to have memory tracking apps when he needs to diagnose system slow downs.

To keep track of how much memory is being used by his mission-critical apps, Power Downloader uses FreeMeter. With this free program on his computer, Power can track disk space usage, memory usage, disk transfer rates, and more all from … Read more

CEO sees less Intel and more Nvidia in PCs

The graphics processing unit (GPU) is in, the central processing unit (CPU) is out. That was one of the main themes running through the Nvidia fourth-quarter conference call earlier this week. Nvidia is the largest graphics chip supplier.

During the call on Wednesday, Jen-Hsun Huang, President and CEO of Nvidia, repeated one thing often: GPUs are playing more of a central role in PCs, CPUs less so. "The CPU has become fast enough for the vast majority of (PC) users," he said. "PC enthusiasts, gamers, and design professionals have know this for some time." The GPU … Read more

Mobile Penryn: early test results

Intel introduced its Penryn mobile processors today, and Dell sent us a Latitude D630 with one of the new chips last week to test against an identical Latitude with a previous-generation Merom chip. As we found last year when we tested the first Penryn desktop chip, the Core 2 Extreme QX9650, performance gains aren't immediately evident. While the Penryn mobile processor we tested, the Core 2 Duo T9500, boasts a more efficient 45-nanometer manufacturing process, it really is just laying the foundation for architectural advances that Intel will release later in the year with Nehalem. Compared with the previous-generation … Read more

Report: November launch for AMD Phenom chips

Since AMD released its Barcelona server chips last month, PC users have been wondering when that native quad-core goodness might arrive in the form of AMD Phenom desktop CPUs. According to a report on VR-Zone, we'll see the first two quad-core Phenom chips next month. The site reports that the 2.2GHz Phenom X4 9500 and the 2.4GHz Phenom X4 9600 will launch sometime in November. These Phenom 9000-series parts will feature 512KB of L2 cache per core, 2MB of shared L3 cache, a 3.6GHz HyperTransport 3.0 bus, and an 89W power rating. A third chip … Read more

Killer Download: Does your computer have what it takes?

No matter what kind of computer you're running--a brand new dual-core Alienware model or your aunt's old Dell laptop--it's hard to gauge the performance of your machine by factory specs alone. Especially with all the versions of Windows PCs out there using any number of hardware configurations; it's tough to really know how your computer measures up to today's fastest systems.

Finding complete system specs is especially important to gamers of course, but they're not alone in their need for system speed. Today's release of the graphics-intensive specs for Crytek's Crysis (from Crave, CNET's gadget blog) surely has many gamers praying their computers have what it takes to really bring the long-awaited game to life. But even if you're not a gamer, you might want to know, for example, whether your computer can handle the latest image- or video-editing software. Fortunately, you can find out in advance using a good benchmarking app. This category of software runs several diagnostic tests which check everything from processor speed and drive efficiency to the output of your graphics and sound cards.… Read more
