On the eve of the GeForce GTX 280 launch just last week, ATI unveiled a bombshell—a brand-new GPU architecture that utilized better process technology and a more power efficient design to outperform Nvidia's gargantuan new GPU. ATI eschewed the huge, hot monolithic GPU for a more compact, but modular core. With twin goals of decreased power consumption and more efficiency per die area, ATI looks poised to dethrone Nvidia, and all without building a videocard that sports an aural footprint roughly equivalent to a Dyson vacuum cleaner.
With the new RV770 GPU comes two products, the $200 Radeon 4850 and the $300 Radeon 4870. While their prices vary wildly, the videocards all use the same GPU. Click the jump to find out exactly what makes it tick.
From the Air to the Pro, Apple’s MacBooks are winning the hearts and minds of consumers everywhere—including PC enthusiasts. Maximum PC investigates whether the hoopla is warranted.
What do you really get for the money when you throw down for a MacBook, and how do these Apple computers compare to their PC counterparts in terms of performance, features, overall usability, and price? Maximum PC tests and reviews the MacBook Air, the standard MacBook, and the MacBook Pro against five PC models sporting similar price points and formfactors. It’s time we set the record straight.
Watching the ongoing race between AMD and Nvidia to build the ultimate graphics processor reminds us of the tale of the tortoise and the hare. AMD has played the hare, aggressively bounding ahead of Nvidia in terms of process size, number of stream processors, frame buffer size, memory interface, die size, and even memory type. Yet Nvidia always manages to snag the performance crown. The GeForce 200 series is but the latest example. We lay hands on the smokin’-fast GeForce GTX 280. Could this be the graphics processor to finally tame Crysis? We reveal what makes the card unique and how its architectural advances translate in the benchmarks!
Fragmentation forces the drive head to jump all over the place to find the bits and pieces of files whenever you access them. Defragmentation, then, is the means by which these files are realigned into contiguous chunks. Windows Vista does this automatically, only the slow speed at which it defrags makes us wonder: Is the time spent worth the supposed performance payoff? And do third-party defragmenters, free or otherwise, do a better job? Should you spend money on third-party defrag tools? Our extensive experiments put commercial utilities (and Vista's built-in solution) to the test!
As much as we would love for our computers to work perfectly, the fact is that PCs and gadgets are complex devices that often fall short of exactly what we want. When confronted with this fact, we’re reminded of the old saw that says if you want something done right, it’s best to do it yourself. And who are we to doubt that kind of wisdom? As power users, we’re not content with hardware the way it comes out of the box; we have an insatiable need to hack our electronics in ways that will improve performance, functionality, and ease of use. And there’s no doubt about it, modifying your hardware will increase your productivity and make your life that much simpler.
