It is a common mistake to mix the terms TDP (to make it clear, thermal watts) and consumption(electric watts). In this article, we will explain exactly what TDP is to which manufacturers refer in their processors, how to calculate it, how to use it, and why it is very important.
TDP (which literally means Thermal Design Power) is strictly the measure of thermic output of an ASIC (or, using other words, the thermal heat generated by the processor), which defines the necessary thermal solution to achieve its nominal performance.
How to calculate TDP
The formula to calculate TDP is the following:
TDP (watts) = (tCase°C – tAmbient°C)/(HSF Θca)
- tCase°C: The maximum temperature to the union between IHS and the processor’s die to achieve the nominal performance.
- tAmbient°C: The maximum temperature of the ambient at the entrance of the sink fan to achieve the nominal performance.
- HSF-Θca (°C/W): The minimum value of temperature per watt of the sink fan to achieve the nominal performance.
With these data in hand, let’s see an example with the new processor AMD Ryzen 7 1700, which as a 65 watts TDP.
What is the best processor for gaming? In this processor comparison, we have only chosen the best processors from each category.
The situation as it stands now (March 2017):
The Ryzen R7 line has been released. (This corresponds to Intel’s i7).
- The positive points: AMD has come out with some very good CPUs (8 cores) at very reasonable prices. This has lead to Intel significantly lowering their prices.
- The negative points: The architecture of these processors suffers from a small memory limitation which makes them less powerful for gaming than their INTEL i7 counterparts.
- Nuanced interpretation: It should be said that the Ryzen 7’s performance characteristics are still very good, and there is a very strong possibility that this processor will never cause you any game-play limitations.
Gamers should await the release of the Ryzen R5 line (which corresponds to Intel’s i5 line) in order to get the Ryzen CPU with the best performance to price ratio for gaming.
What is INTEL’S reply to these new RYZEN CPUs?
Intel will sharply decrease their prices in order to respond to the release of the new AMD Ryzen CPUs.

The situation as of January 2017:
The new Kaby Lake generation of Intel processors (January 2017) does not really bring anything new to the high-end processor market. In actuality, the performance increase, relative to the old Sky Lake generation, is only on the order of 3%.
In the last few years Intel has given us almost insignificant upgrades while steadily rising its prices. All in part because of AMD’s inability to offer a competitive processor. That’s over with Zen architecture. It’s all we expected and more and it will bring with it a renewed competition that will once again boost processors development, at least for the moment, in desktop systems.
The first models to hit the market are the Ryzen series 7. They will not be much different than inferior models, but they are the perfect example of what this architecture can offer to the domestic and professional users. These are eight-core processors where, for the first time in the history of AMD, the ability to process in two parallel threads by each of the cores is introduced.
After spending dozens of hours testing numerous models, I have concluded that the Asus C300 is the best inexpensive laptop.
1 – Acer Chromebook 14: Obtaining elegance and performance without going broke
If you are looking for a laptop which is not just fast but also well-built and with a great aesthetic design, the Acer Chromebook was certainly made for you.
With its entirely aluminum case and sleek design, this laptop is really easy on the eyes.
And the best thing about it is that not all the attention was paid to its design. It is fast and well-built. The Acer 14 also has a battery which can provide up to 12 hours of charge.
ASUS has some of the best manufactured laptops in the market. Especially its mid and high range of ultrabook laptops and convertibles made of aluminium. Laptops in which Asus integrates engineering, design, autonomy, sound and of course image quality.
14mm thickness. This is what this convertible laptop with touchscreen has, and is an aspect that adds to the screen thickness. Completely made in aluminum with that pretty anodized “purple” color of ASUS. Anodized and brushed with a circular treatment around the ASUS logo in the screen cover.
It’s a slim and light laptop, 1.2Kg with battery, where you can enjoy the latest in technology with an autonomy up to 12 hours thanks to its built-in 52Wh battery. It has a 360-degree screen rotation. It can switch into a 13 inch Tablet or use any position in between. The only bad thing I can notice is that ASUS didn’t properly protect the edges for the tent mode, the one you see in the picture.
At the time of buying a computer, part by part, one of the components that least receives attention is the power supply. This component is key for the correct functioning of the computer. We will explain why is not enough to say “I’ll just use the same 600W power supply”. When choosing a power supply, we have to check many factors, which can be summarized in quality of the components, stability, security, efficiency, power and quality.
The higher the quality of the components, the longer will be the useful life of the power supply. In addition, higher quality power supplies usually have a longer warranty, from 5 up to 10 years. A poor quality power supply could have a shorter useful life and damage other components if it fails.
Stability and security
Better components imply higher stability in power input. Furthermore, when buying a power supply, you have to look at the maximum time it can stay on without electricity. This is good to know in case there is a voltage drop. The minimum acceptable is around 17 milliseconds.
What is a Chromebook, exactly? You have probably heard people talking about Chromebooks, those strange computers that don’t run Windows, but that have other specific advantages.
In this article, I will give you a concrete explanation of what a Chromebook is and what the differences are between it and a Windows portable computer as well as its advantages and downsides.
Chromebooks, what are they?
Chromebook is the generic name given to portable computers which are based on the Chrome OS. It is not just portable computers that use this operating system, but it is more common to find it being used on a portable computer.
- Beautiful Convertible screen

The Acer Chromebook CB5-132T succeeds at being aesthetically appealing, practical and fast, all while keeping its price low thanks to the use of the Chrome OS. Keep reading to find out if this Chromebook is really worthwhile.
Being a student of several years myself, and having used a laptop every day in my classes and for working, I can say that, in my opinion, the Toshiba Chromebook 2 is the best laptop for college students.
1 – The laptop with the best quality/price ratio
The laptop with the best ratio of quality to price is the Toshiba Chromebook 2.
Its IPS Full HD display is excellent, its battery easily holds a charge for 6 to 8 hours, its light – 1.3 kg – weight makes it very easy to transport, and it it powerful enough to take notes in class and surf the web without any difficulty.
The display on the Toshiba Chromebook 2 measures 13.3 inches, which makes it highly mobile while remaining large enough to be comfortable for working at. It offers very decent sound and its refined design makes it stylish.
