Bicicleta sem rodas
Bicicleta sem pneus
Hoje, há bicicletas de todos os tipos. Mas você já imaginou encontrar por aí uma bicicleta sem... pneus? Ela foi criada pelo designer israelense Ron Arad. Ele usou tiras de aço para fazer gomos. Juntos, os gomos lembram flores. E são elas que ocupam o lugar dos pneus nesta bicicleta. Leia mais (28/09/2011 - 14h17)

Novos relógios de pulso se inspiram em smartphones

URL: http://redir.folha.com.br/redir/online/tec/rss091/*http://www1.folha.uol.com.br/tec/980215-novos-relogios-de-pulso-se-inspiram-em-smartphones.shtml


Ameaçado pelo hábito de ver a hora no celular, o relógio de pulso começa a recorrer a elementos inteligentes dos smartphones. Uma nova geração de empresas aposta em levar aos pulsos das pessoas pequenos computadores, com direito a apps, sistema operacional e Bluetooth. Uma das companhias dando fôlego ao segmento é a italiana Blue Sky, que planeja apresentar no dia 25 de outubro o I'mWatch. O aparelho vai ter Android 1.6, tela sensível ao toque e acesso a aplicativos de música e e-mail. O interesse da indústria pelos relógios inteligentes ganhou força na semana passada com Juha Pinomaa, antigo executivo da Nokia. Ele liderou um grupo de investidores na compra da Meta Watch, a divisão de relógios inteligentes da tradicional Fossil. O valor do negócio não foi divulgado. Leia mais (24/09/2011 - 10h51)

Sony offers 'adjustment' for NEX-5N camera to reduce clicking sound while recording video

URL: http://www.engadget.com/2011/09/23/sony-offers-adjustment-for-nex-5n-camera-to-reduce-clicking-so/


Looks like we weren't the only one afflicted by the Sony NEX-5N camera's annoying click problem. In case you missed it, the camera displayed the annoying tendency of producing an audible click loud enough to ruin any 1080/60p video if it was moved suddenly while shooting. Tonight Sony updated its support site to promise a "performance improvement" available to all owners under the camera's warranty that it claims reduces the sound. At the moment we don't have any more information on what's causing the sound or what the improvement entails, but owners can dial 888-868-7392 to get their units upgraded.

Zotac Z68ITX-A-E Wifi Review - Mini-ITX meets Z68

URL: http://www.anandtech.com/show/4595/zotac-z68itxae-wifi-review-miniitx-meets-z68


With every chipset, there's a call to arms in providing the package that everyone needs. Unfortunately there's never one motherboard which can cater for every possibility, but there are some that come quite close. Our review today is on the Zotac Z68ITX-A-E Wifi - a mini-ITX take on the Z68 chipset, which promises to be a winner right from the start, with dual gigabit Ethernet, USB 3.0, onboard wifi, onboard power/reset buttons, a debug LED, a lot of extras with your motherboard, and all the extras that Z68 offers. For $170, we're looking at a good contender for an award here, as long as the performance and additions compare well to its rivals. Read on for the full review!

Ivy Bridge GPU to Support Resolutions of up to 4096x4096

URL: http://www.anandtech.com/show/4838/ivy-bridge-gpu-to-support-resolutions-of-up-to-4096x4096


Thanks VR-Zone for the image!

IDF 2011 ended on last Thursday but there is still lots of data showing up because sites are processing the data they have gathered. VR-Zone is now reporting that Ivy Bridge's GPU will support resolutions of up to 4096x4096 (commonly referred as 4Kx4K). We took a deeper look at the IB GPU in our Ivy Bridge Architecture piece, but we missed this upgrade. Sandy Bridge's GPU supports only resolutions of up to 2560x1600, so this is a huge jump since 4Kx4K has over four times more pixels. 

It's unlikely that we will see any 4Kx4K displays though, given that 16:9 is the standard nowadays (some higher-end are 16:10 though). That suggests a resolution of 4096x2304, which actually makes more sense given the bandwidth limitations. 4096x4096 at 60Hz with 24-bit color would require a bandwidth of roughly 36Gb/s, more than any of the current display interfaces supports (DisplayPort 1.2 is the king at 21.6Gb/s). 4096x2304 requires only ~20.2Gb/s, and that DP 1.2 can easily provide. 4096x4096 should, however, work with DP 1.2 by lowering the refresh rate to e.g. 30Hz, which would reduce the required bandwidth to be within DisplayPort's range. 

Displays with +2560x1600 resolution are very rare and expensive at the moment though. Back in June, EIZO announced a 36" monitor with resolution of 4096x2160, with a whopping price tag of $36,000 (yes, that is three zeros). However, considering that 10.1" tablets with 2560x1600 will soon be reality, it sounds likely that displays with 4096x2XXX resolution will soon be available at reasonable price points too.

Ivy Bridge has three new features for overclocking:

  1. The max CPU ratio is now 63x up from 57x
  2. You can now adjust CPU ratios without a reboot, just via a register write.
  3. DDR3-2800 will be the maximum DRAM frequency.

3TB Hard Drive Round-up: Hitachi, Seagate, WD

When we reviewed our first 3TB hard drive almost a year ago, the market wasn't quite ready for the huge storage capacity being made available. Fully compatible motherboards featuring the unified extensible firmware interface (UEFI) were still months away, and having to use a separate host bus adapter (HBA) card was inconvenient and added extra...

Intel Leaks i7-2700K

URL: http://www.anandtech.com/show/4757/intel-leaks-i72700k


Intel's Sandy Bridge CPUs were launched in January and so far, the desktop i7 lineup has consisted of three SKUs: i7-2600, i7-2600K and i7-2600S. Earlier this week, Intel released 16 new Sandy Bridge CPUs, but the desktop i7 series remained unchanged. Yesterday, Intel updated their Material Declaration Data Sheets (MDDS) with product code for i7-2700K. The exact product code is:

BX80623I72700K SR0DG

For comparison, the product code for i5-2500 is:

BX80623I52500 SR00T

Lets break down the product codes. The first two letters, "BX", stand for boxed unit. These letters would be different if the unit wasn't a boxed unit, for example "FF" is for non-boxed PGA988 units. There could be a third letter "C" which means it's a boxed unit for China market (hence there are two product codes for i7-2700K). After that, there is a five number code "80623". This is a specific code for all boxed desktop Sandy Bridge CPUs. Finally we get to the processor number which is the most interesting part and in this case, revealed the i7-2700K. There is still a separate spec code after the processor number and it's processor specific as well. 

The specs of i7-2700K are unknown though. It's also a question whether there will be i7-2700 and i7-2700S or not. However, we would expect i7-2700K to carry similar specs as i7-2600K (four cores, Hyper-Threading, unlocked multiplier, 8MB L3...), but a slightly higher default frequency. Given Intel's history, 100MHz (one multiplier) increase sounds likely, making i7-2700K's stock frequency 3.5GHz with up to 3.9GHz Turbo. Price wise i7-2700K should also replace i7-2600K, making its price ~$317.

There is no word on the availability of i7-2700K. Leaked roadmaps suggest something equal or better than i7-2600K between Q3'11 and Q1'12. Considering that Intel just released new CPUs a few days ago, it seems unlikely that the release is imminent. On the other hand, it makes no sense to release i7-2700K just before Ivy Bridge, thus our guess would be Q4'11, around the same time as AMD's Bulldozer hits the shelves.
