The race of the petaflops: These are the ten most powerful supercomputers in the world

February 27, 2018 by Lincoln

Some time we have shown you examples of supercomputers, those incredible equipment in power and size that are necessary tools for the tasks of prediction and design in scientific and military fields. In the beginning of time this was something quite American, but today the globe is full of examples that bother and even surpass the ‘USA’ artillery, something especially recognizable if we go to China.

Accustomed to comparing domestic equipment in the teraflops scale, to measure the dexterity of these mega computers we have to go up to the petaflops. For those who are lost with the nomenclature, in the computer world, the floating-point operations per second are used to measure the performance of the equipment.

Intel returns to the charge with a few Optane SSD 900P reserved for gaming and workstations

February 15, 2018 by Lincoln

Our analysis of the first Intel Optane units that this manufacturer brought to the market left us with mixed feelings that did not make it very clear if this storage technology could become a reference in a market dominated by traditional SSDs.

It seems that Intel strongly believe that it is, because they just presented the Intel Optane SSD 900P Series, a new family of solutions based on 3D XPoint technology in this case, yes, is aimed at users of gaming equipment and those of work stations, where of course the preliminary benchmarks of Intel promise excellent performances.

Batteries of our mobile devices have become protagonists of our user experience, but a lot are also critical components in laptops do. Has the technology integrated in these batteries improved? What is the best way to squeeze these components and extract the most out?

This is what we will try to explain by clarifying some of the most important myths and realities of portable batteries. If you want to know when you should charge your laptops, if you must have them plugged in all the time or what happens with the recharge cycles, attentive.

Ryzen Threadripper 1900X: AMD also has an affordable beast, even for gaming

November 23, 2017November 11, 2017 by Lincoln

A few days ago AMD introduced its new Ryzen Threadripper processors, which are focused on more professional experiences that require full power. At first it was said that these processors were not designed for gaming, something very similar to what happens today with the Intel Core i9, but AMD is taking advantage of SIGGRAPH 2017 to show a new version of its management program ‘Ryzen Master’, that will allow us to enable an interesting ‘Game Mode’.

Why are printed circuits usually green?

November 4, 2017 by Lincoln

The vast majority of plates with printed circuits that we see in the market usually have that characteristic green color of all known: we have seen it in the Raspberry Pi for example, but also in many other solutions.

Why this green color and not another? In fact it is possible to find plates with printed circuits in many other colors, but that green has become a de facto standard without anyone seems to be clear about the reason. There are some theories about it, however …

Gigabyte overclockers upgrade to Intel Core i7 ‘Kaby Lake X’ up to 7.5GHz

August 29, 2017 by Lincoln

The extreme overclocking is as it is, practically no use and a lot of showmanship in the figures. It seems that Intel and associates intend to have a lot of fun with this in the early days of their Core X family of processors.

ASUS Zenbook Flip S: An ultra-thin convertible that bets on power

August 9, 2017 by Lincoln

ASUS continues to bet on the thinness and feather weights in its new devices. During Computex 2017 event, the Taiwanese company has presented this morning its latest convertible notebook, the ASUS Zenbook Flip S. Its main attraction is that it is the thinnest convertible in the world, and ASUS also defines it as one of the lightest.

The laptop comes equipped with Intel Core processors of the seventh generation, includes a screen that can reach 4K UHD resolution, and as a good convertible its lid can open 360 degrees to enter the “tablet mode.” With these features and a maximum range specifications, the device is an interesting response to alternatives such as the new Surface Pro from Microsoft.

Acer Switch 5: More wood for a convertible that boasts of Kaby Lake and liquid cooling

July 6, 2017 by Lincoln

Last year in the presentation of a singular convertible by Acer: the Switch Alpha 12 highlighted by a unique design support, but above all by a liquid cooling system called LiquidLoop that allowed integrating powerful processors without the need to use traditional fans.

That success is repeated in the Acer Switch 5, which now come with new Intel Core i5 and Intel Core i7 seventh generation (Kaby Lake) that bring more efficiency and power to these flashy 2 in 1.

Acer Swift 7, the thinnest laptop in history

June 7, 2017 by Lincoln

The ultrabooks sector has advanced rapidly in recent years motivated by this sector of consumers who want laptops that really are. In addition, the ultrabooks have advanced hand in hand with the ultra low power processors, which have been rising notably power, also becoming more versatile for use in a professional environment.

The Acer Swift 7 model is one of the last additions to this sector, aimed at those who want a lightweight equipment but that can be used without problems in everyday tasks and presuming thinness less than one centimeter thick.

Intel Optane and the half-measures: Do these memories solve a current problem?

May 15, 2017 by Lincoln

The introduction of the new Optane family of memory drives comes after years of development and promise to bury the traditional hard drive. In fact, Intel seemed to indicate that its non-volatile XPoint 3D memories might even make it difficult for successful SSDs.

Things are not so clear now that the first units have reached both the business market and the end user market. At least in the second case we find small units and whose advantages, no matter what Intel says, show no revolution in the current market. It seems rather that Intel wants to invent a solution to a problem that (already) does not exist.
