Prenium d procssor4/1/2023 ![]() You can set it so that the light automatically turns on in dimmer environments, or you can manually adjust it between three different levels – off, dim, or normal brightness. Unlike some cheaper laptops that I’ve recently tested, I didn’t experience a quick bottoming out experience, which adds to typing comfort.īacklighting is also supported on the keyboard. There isn’t any flexing when typing, and though you won’t get the premium typing experience found on Lenovo’s more premium ThinkPad keyboards, the keys here are comfortable to type on with decent key travel. The hard plastic shell is nice, as it not only reinforces the cover and helps to protect against screen damage when the keyboard is closed, but it also makes the keyboard feel sturdy when typing. On the inside, you get a hard plastic cover over the keyboard deck with keys arranged in an island-style layout. ![]() The choice of softer fabric is a bit concerning for a surface that would touch tabletops, especially for those who work in communal spaces like coffee shops, but I found that the cover has held up and there isn’t any staining or wearing after several weeks with the Duet. With Lenovo’s implementation, you get a color-matched fabric cover on the exterior that feels like twill. The keyboard, like the Type Cover on the Surface Pro, feels solid. Lenovo claimed that the battery inside the keyboard portion can last for 28.3 hours of continuous typing with no backlight enabled. This more ergonomic experience helps reduce neck strain and improves the ergonomics of using this tablet. My neck is definitely grateful to Lenovo for this implementation, as I can use a tablet stand when I am doing work at a coffee shop and type on the same keyboard instead of having to tote around a secondary Bluetooth keyboard. This nifty trick makes the folio keyboard far more useful, and I didn’t realize how much I would love this feature until I actually used it. I had hoped that with a less premium processor, Lenovo could have figured out a fan-less base model – after all, Apple’s now discontinued 12-inch MacBook was fanless as is the entire iPad lineup. The Duet uses fans for active cooling – even on our lower-end Core i3 configuration – though at about 35 to 40 dBa at ear level, the fans are quieter than most laptops we’ve tested. There are vents located on the top edge of the tablet in landscape orientation and also on the sides concealed just beneath the speaker cutouts. Magnets on the Duet’s screen will also help keep the keyboard attached to the screen when closed, which makes the entire package easier to travel with. Like the Surface, the keyboard will magnetically adhere to the slate when connected. POGO pins on the bottom and some cutouts help to connect the keyboard to the Duet. And since Lenovo didn’t put its own take on Microsoft’s proprietary magnetic connection, the downside is you don’t have the convenience of a magnetic connector for charging the Duet. Are either of them worth it? Let's try to answer these and other pertinent questions with a closer look.And as there is no Surface Connect port on the Duet, you’ll either need to rely on USB-C for your docking needs if you want a single-cable connection to connect power, peripherals, and display to Lenovo’s slate. Which is better? High clock speed and HT, or relatively low MHz and two cores. The end result is dual-core loving that comes in at a more palatable £200 or so. The Pentium D 820 runs in at 2.8GHz, sports the same dual-core setup as its bigger brother but does not support Hyper-Threading. On the other hand, the near-£700 3.2GHz Hyper-Threading-capable Pentium 840 gets a little brother. All the same internal gubbins just 200MHz faster and, obviously, more expensive. The Pentium 4 660, which is a 3.6GHz Prescott-based Pentium 4 with 2MB of L2 cache, will now be superceded by, wait for it, the Pentium 4 670. Today Intel's officially releasing Pentium-based CPUs that offer both high clock speed and dual-core loveliness, although you won't get both in one package. Parallelism (and the price paid for it) can be both wonderful and mediocre it all depends upon your viewpoint and usage. Indeed, if you read our Intel Pentium XE 840 review, the ultra-expensive dual-core processor posted gaming results in line with a 3.2GHz single-core CPU. Single-threaded application performance, and I'm primarily thinking of gaming here, showed no benefit. Dual-core CPUs, in a nutshell, offered huge and expected gains in applications that were multi-threaded in nature, with each core beavering away at code. Both rivals launched their own dual-core, consumer-level CPUs with much fanfare. The last two months have been rather busy on the CPU front. Introduction Intel Pentium 4 670 and Pentium D 820Īnother month passes and another couple of processors are released by either Intel or AMD.
