Ask Engadget: what's the lightest laptop with discrete graphics?
We know you've got questions, and if you're brave enough to ask the world for answers, then here's the outlet to do so. This week's Ask Engadget inquiry is from Steve, who wants to shed weight but retain power for his next mobile computer. If you're looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com. "I'm a professional motion graphics editor looking for a laptop to take on the road with me. While I like the idea of a Haswell-powered machine, I'm really looking for a machine with proper discrete graphics. Is there an Ultrabook or really light laptop that marries both? Thanks!" Our first thought was to look at Lenovo's W-Series, which offers a 2GB Quadro K2000M on the higher-end models and weighs in at a comparatively svelte 2.61kg. If, however, you want power and the ability to sneakily game while on planes, then there's one of Alienware's 14-inch units, which offer a GeForce GT750M and a weight of 2.7kg. Finally, you could always break the bank with a Retina Macbook, which offers a GeForce GT650M as a build-to-order option but weighs a relatively slender 1.02kg. That's three from us, we bet the Engadget Community can find you something even lighter.
NVIDIA: there's nothing 'Ultra' about Ivy Bridge Ultrabooks unless you add Kepler
This is a vaguely awkward message for NVIDIA to be putting out. On one hand, the company is best buddies with Intel and is hoping to see its next-gen GPUs bundled with a large portion of the Ivy Bridge notebooks that will ship this year. But to reach that target, it must risk irking Chipzilla by emphasizing the limitations of Ivy Bridge's integrated graphics. That's exactly what happened at a recent presentation, when NVIDIA told us there'll be "nothing Ultra" about the performance of a regular Ivy Bridge Ultrabook because the integrated HD 4000 graphics will only handle around 43 percent of current games. By contrast, if you add in a GeForce GT 640M you'll find that 100 percent of current games are playable with frame rates over 30fps and high detail settings, including Battlefield 3, Batman: Arkham City, Crysis 2 and many others. If you leave the lightweight Ultrabook spec behind and combine Ivy Bridge with a GT 670M GPU then you can go even higher -- as we just discovered in our review of the MSI's GT70 gaming laptop. Fortunately, Intel was pretty magnanimous about HD 4000 when it briefed us, and readily accepted that enthusiasts will still want discrete graphics, so we don't imagine the slide above will cause too many hurt feelings.
Daily Mac App: gfxCardStatus
Some newer MacBook Pros have been packing dual graphics cards for a while now, with the ability to dynamically switch between them -- integrated for battery life and discrete for performance. It's often tricky to know which card is currently in use as the switch between the two is seamless. That's where gfxCardStatus comes to the rescue. Sitting up in your menu bar, gfxCardStatus shows you at a glance which card is currently active, but more than that, it actually allows you to manually switch between the GPUs. A drop down menu provides you with three options: Integrated Only; Discrete Only; and Dynamic Switching, which is the system default that lets OS X decide which graphics card is required. If you want to save as much battery power as possible, leaving it on integrated only will ensure that the power hungry discrete GPU doesn't fire up. On the other hand if you want maximum performance all the time, then discrete only will make sure the most powerful GPU is fired up. For most situations OS X does a decent job of managing power considerations, but if you want a little more control, gfxCardStatus will let you set up GPU power schemes to define which chip is used depending on power source. gfxCardStatus is one of those little apps that's both useful and doesn't get in your way. You won't need it a lot, but if you're on battery power and you want to keep working for as long as possible, the little menu bar app can be a life saver. It's freely available (donations accepted) to download from the developer's site and is Lion-ready.
NVIDIA announces GeForce GTX 580M and 570M, availability in the Alienware M18x and MSI GT780R (updated: MSI says no)
We know you're going to be shocked -- shocked! -- to hear this, but NVIDIA's gone and refreshed its high-end line of GeForce GTX cards. The GTX 580M takes the place of the GTX 485M, and NVIDIA's bragging that it's the "fastest notebook GPU ever," capable, we're told, of besting the Radeon HD 6970M's tesselation performance by a factor of six. The new GTX 570M, meanwhile, promises a 20 percent speed boost over the last-generation 470M. Both 40-nanometer cards support DirectX11, OpenCL, PhysX, CUDA, 3D Vision, Verde drivers, Optimus, SLI, and 3DTV Play. As for battery life, NVIDIA's saying that when coupled with its Optimus graphics switching technology, the 580M can last through five hours of Facebook, but last we checked, that's not why y'all are shelling out thousands for beastly gaming rigs. You can find the 580M in the Alienware M17X and M18X (pictured) starting today, though you might have to wait a week or so for them to ship. Meanwhile, the 570M is shipping in the MSI GT780R as you read this, and you'll also find the 580M in a pair of 3D-capable Clevo laptops: the P170HM3 and the SLI-equipped P270WN. Handy chart full 'o technical details after the break. Update: An MSI rep has let us know that contrary to earlier reports, the GT780R is not currently available with the 570M graphics card. The company added that it will offer some unspecified laptop with the 570M sometime in the "near" future. It's unclear if that laptop will, in fact, be the GT780R.
NVIDIA losing ground to AMD and Intel in GPU market share
NVIDIA may be kicking all kinds of tail on the mobile front with its ubiquitous Tegra 2 chipset, but back on its home turf of laptop and desktop graphics, things aren't looking so hot. The latest figures from Jon Peddie Research show that the GPU giant has lost 2.5 percentage points of its market share and now accounts for exactly a fifth of graphics chips sold on x86 devices. That's a hefty drop from last year's 28.4 percent slice, and looks to have been driven primarily by sales of cheaper integrated GPUs, such as those found inside Intel's Clarkdale, Arrandale, and most recently, Sandy Bridge processors. AMD's introduction of Fusion APUs that combine general and graphics processing into one has also boosted its fortunes, resulting in 13.3 percent growth in sales relative to the previous quarter and a 15.4 percent increase year-on-year. Of course, the real profits are to be made in the discrete graphics card market, where NVIDIA remains highly competitive, but looking at figures like these shows quite clearly why NVIDIA is working on an ARM CPU for the desktop -- its long-term survival depends on it.
ATI overtakes NVIDIA in discrete GPU shipments
You'd think with ATI having the performance, value and power efficiency lead for so long -- at least since the Radeon HD 4000 series -- NVIDIA would be in all kinds of trouble, but it's only now that AMD's graphics division has finally taken the lead in quarterly shipments. This is according to Mercury Research, whose analysts place the split at 51 to 49 percent in favor of ATI -- still a tightly contested thing, but it compares very favorably to the Red Team's 41% share in the same quarter last year. This data is concerned with discrete GPU shipments only (laptops included), whereas on the integrated front Intel continues to reign supreme with 54 percent of the market shipping its cheap and cheerful IGP units. ATI has made forward strides there as well, however, with 24.5% ranking ahead of NVIDIA's 19.8%. If Apple shifting its iMac and Mac Pro lines away from the Green livery wasn't enough, perhaps these numbers will finally start ringing some alarm bells over at NV HQ. [Thanks, Zubayer]
MacBook Pros with NVIDIA GeForce GT 330M graphics get (unofficial) discrete switching utility
We've lamented the way Apple's latest MacBook Pros switch between their integrated Intel graphics and the NVIDIA-sourced, power-sapping discrete silicon pretty much since day one (we're sorry, but Tweetie just doesn't need all the horsepower our systems have to offer). Apple has yet to pony up an official solution, but a neat little utility -- Cody Krieger's gfxCardStatus -- has been quietly evolving over the past few weeks into a decent substitute. Originally designed simply to let you know which chipset's currently in use, the latest version, 1.6.1, now allows you to toggle amongst them by hand. It's said to still be a little bit on the buggy side, but we're delighted (and not really surprised) to see that the community came to the rescue in short order when Cupertino didn't. [Thanks to everyone who sent this in]
MacBook Pros with NVIDIA GeForce GT 330M silicon making questionable graphics switching decisions
"With every choice you make, ask yourself: is this a good choice, or is this a bad choice?" That's the sage advice we were constantly given as tykes -- and it's advice that replays in our feeble brains every day as we write news. Turns out it's also a piece of wisdom Apple's latest round of MacBook Pros would be wise to heed, because currently, they're making some awful decisions about when to turn on that power-sapping NVIDIA GeForce GT 330M discrete chipset. Read on to see what we mean. [Thanks, Tom]
