In the constant competition in the market of technical novelties, the focus is always on the most productive and advanced solutions. But in addition to them, budget products are also in constant demand, which meet the basic requirements and are accessible to a wide range of consumers. Among them is the Hewlett-Packard HP 250 series notebook, which this review is devoted to. HP 250 G3 belongs to the business class of inexpensive laptops and it, in general, has already been discontinued. Some remains can still be caught in the store, but they should be supplanted by the newer HP 350 models. Nevertheless, and with the example of such a laptop you can get a general idea of ​​this class of devices. At the same time, we will test the budget graphics of NVIDIA GeForce 820M, which is still used in cheap laptops. Let's see what its potential is, and whether it can be considered at least as a minimal game option.

If you are looking for a laptop with a higher shelf, then in comparison you will also see good laptops from the offers of various stores so that you can find the best price offer. A good laptop is what is characterized. They can be used to store system data and programs to make the most of them. Small laptops or attitude towards convenience.

For the same money

The smallest notebooks under 15 inches are called netbooks. They are useful for students, businessmen and people who often move. A portable computer with small weight and small size provides greater mobility without weighing the luggage and spine. Choosing a small laptop, you will have access to your documents anywhere and anytime. These devices provide a long battery life, so you can use them for a long time without access to an electrical outlet.

Since the laptop HP 250 G3 (L3Q09ES) belongs to the category of inexpensive devices, the packaging is as simple as it is - a faceless cardboard box.


Inside the box, in addition to the notebook itself, there is an external 65 Watt power supply and documentation.


You can successfully use the time spent on a plane, waiting room, train or trip on a long car. Small does not mean the worst - the netbook is suitable for work, completion of projects on the go, as well as watching movies and serials on airplanes and hotel rooms.

Design, color, design - the look of the laptop is important. The laptop often travels with us, making it a showcase that expresses our style. When laptops were mostly black, now we can choose between different colors and materials. Elegantly presented models - brushed aluminum, highlighted by its matte silver surface. We also find laptops with a red, blue and even a purple coating. Among gaming laptops - models with a highlighted keyboard that looks modern and facilitates the gameplay at night.

The HP 250 G3 is made in a simple plastic housing in black. The surface is slightly rough, on the front side there is the HP logo.


The lower part has slots for air inflow in the center and closer to the front side. There are small rubber feet. At the edge of the card slot is visible for SD memory cards.

Another, but very practical feature is the touch screen on laptops. Laptops with a touch screen combine the capabilities of a laptop computer with a tablet. When we are comfortable using tablet functions, we can turn the screen and manipulate it with your fingers. This option works for browsing the Internet, reading e-books and games in fitness games. Touch screens also benefit from graphics - the latest graphics programs work with touch screens, which in combination offers features similar to graphics tablets.

Modern laptops have different shapes of the case - some are more ordered, others - more sharp silhouettes. It combines the fact that they become slimmer, which not only looks good, but also makes them less room in a bag or backpack. Today you can almost forget about the separate baggage carrying laptops. Miniaturization is converted into user convenience. The choice between a more rounded or square shape is a matter of taste, and producers try to satisfy a wide variety of tastes.


The design does not provide separate removable covers, which opens access to memory slots to increase RAM. Only the battery is used.


The exhausted hot air is blown out through the holes on the left side of the notebook. Nearby there is a power connector and a Kensington security lock, DVI, HDMI, Ethernet, USB 3.0 and a combined audio jack.

In the ranking you will find excellent laptops. You can also sort by popularity, referring to products recommended by other users. Their products are distinguished by modern design and the use of components of the highest quality. Their characteristic feature is the combination of special applications and subtle shapes. These are devices suitable, for example, for computers for employees. Using our comparator for laptops, you easily find yourself in a bundle of deals and choose the perfect laptop.

Convenience, design and, above all, ease - these are just some of the advantages of laptops. But what, apart from aesthetics and ease of movement, should be considered when choosing a laptop? Screen: One of the most important problems that arise when working with laptops is the screen diagonal. However, the parameters of this element do not end there. We also need to pay attention to its resolution, as well as the type of matrix - available glossy or matte.


On the right side there are two USB 2.0 ports and an empty space for DVD-drive, which in this version is not.


The working surface around the keyboard is lighter, but the same is not as bright as the main body. The screen is a diagonal of 15.6 inches. It is executed on the TN-matrix with a resolution of 1366x768. The screen has a matte finish. The image quality corresponds to the general level of such devices. Complaints can cause small viewing angles, but this affects all budget laptops.

Keyboard. Theoretically, the problem is very simple in choosing a laptop, but nothing more. In the market we have available keyboards with numerical functions or without them. We can also choose, depending on the layout of the buttons and the level of the key stroke. Therefore, when buying, it is worth checking whether a particular keyboard is convenient for everyday use.

Parameters: what parameters we choose depends largely on the purpose of our computer. For us, a completely different laptop will be enough, if we expect only effective office software and Internet browsing capabilities. On the other hand, we will definitely choose another device when we are witty players, and our games require better and better parameters.


Black keyboard without backlight. There is a digital block. From the nuances it should be noted that in this notebook the top row of keys F1 ... F12 by default works as multimedia buttons, adjusting the volume, brightness, etc.


The most important in terms of performance is the processor. However, for a typical office use, a model with a lower mark is sufficient. Those who dream of a typical laptop should pay special attention to the battery of their laptop. Producers to extend their lives, offer us solutions such as: increased battery capacity, more cameras and an additional battery. Computers, whether stationary or portable, are mostly hard drives. Of course, everyone knows that the more capacity, the more data we can store on it.

The laptop is based on an Intel Core i3-4005U processor with two physical cores, which, thanks to Hyper-Treading technology, can process data in four streams. Operating frequency is 1.7 GHz. The processor belongs to the Haswell architecture and is made in the SoC format (system on a chip) with a modest TDP of 15 watts.

This is much more than offering integrated graphics cards. The power of the keyboard: the performance of the most commonly used keys after 10 million strokes and touchpad buttons 1 million strokes. Do not worry, you will end your romance. Current up to 900 mA not only provides stable power for peripheral devices, such as external drives, but also allows faster charging of rechargeable batteries for connected phones or tablets.

It also has a faster startup and shutdown compared to previous versions of the system. This allows you to quickly and easily move between applications, move items and move from one place to another. If you are looking for a universal laptop at this price, check out our recommended configurations.


Four gigabytes of memory are collected by a single DDR3 bar with a frequency of 1600 MHz. For data storage, a Hitachi Travelstar Z5K500 hard drive with a capacity of 500 GB is installed with a spindle rotation speed of 5400 rpm. The network capabilities are 100 Mbps Ethernet and Wi-Fi 802.11 b / g / n. There is a compulsory Bluetooth and SD-card reader.

Memory subsystem

Universal laptop computer. The case is hard and carefully processed, unfortunately, it does not allow you to quickly replace the battery. A large terabyte hard drive, of course, will not quickly fill up. The desktop is huge, which increases the comfort of working with applications and programs.

Nevertheless, it is an excellent laptop for home use, which is worth the money spent on it. Powerful configuration case with backlit keyboard. . Unfortunately, the battery is small, and the tests fell below expectations. It allows you to run new games, but at lower resolutions and reduced detail. The brightness does not differ from the average.

The graphical system is represented by two devices. The processor has built-in graphics Intel HD Graphics 4400 with a frequency of 200 MHz (basic value) to 950 MHz. This graphic is active in 2D mode. The processing of 3D takes on the GeForce GT 820M. This video card is based on the GF117 GPU of the Fermi architecture. In the asset of this GPU only 96 stream processors and 64-bit memory bus.

The laptop works quietly and has a large and comfortable keyboard with a numeric keypad. Unfortunately, the screen is glossy and reflects everything in it, like a mirror. It offers a toned style, has a carefully crafted body with good stiffness and a comfortable numeric keypad. Unfortunately, it does not have a backlight. The cooling system is located on the right, and the case heats up when the laptop is intensively used.

For everyday use it is enough to work with office packages, multimedia tandem. The lack of more effective graphics will be felt only by people who would like to use a laptop for games. The advantage of this solution is low current consumption and longer battery life.

The frequency of the GPU can be different, in our case it is 625 MHz. There are also faster configurations. The video card has its own DDR3 memory of 1 GB and a frequency of 2000 MHz. According to the characteristics of the mobile video card GeForce GT 820M closest to the desktop models GeForce GT 610/620. It's hard to talk about some kind of gaming performance. But if the video card is present in the system, then it is something it is capable of. Its possibilities will be clear on the basis of testing results.

Screen with a battery screen. . A modern hybrid ultrabook with 12, 5-inch screen and a modern thin frame. It is convenient and much smaller than the 15, 6-inch models, and has a full-sized keyboard and a large touchpad. This matrix with a touch screen with increased brightness, but, unfortunately, with a glossy finish.

This is a laptop for basic applications. The case has a built-in design and does not allow you to remove a battery weighing just over 1, 6 kg.

  • Hybrid design and wide viewing angles.
  • Average performance built into the battery case.
The case is made of high-quality plastic. Although it is thick and angular, it looks modern and practical.

A discrete graphics accelerator of the middle class for mobile computers isThis video card was released in early 2014 and still continues to be relevant. The presence of such an accelerator allows on the laptop to run most toys even now, but not with the maximum settings.

Niche adapter

To date, laptops, depending on the capabilities of the graphics subsystem are divided as follows:

The screen cover is quite thick and protects the matrix well. The processor offers the right performance for processing office and multimedia packages. Removable filter with fuser. . This is a huge workspace, which allows you to work comfortably with several open programs.

The case is angled and completely made of plastic. A huge touchpad and a large keyboard allow typing and working on a laptop. Unfortunately, the keyboard does not have backlit keys. The battery can be removed and replaced, it has a large capacity, and the battery life of the laptop has reached a good result of more than 300 minutes. Inside the case there is a fingerprint reader.

    Mobile entry-level systems with a minimum level of performance, maximum autonomy and democratic value. Typically, these PCs use an integrated graphics card. In this case, the computer can only run the simplest and least demanding games.

    Mid-level laptops are necessarily equipped with a discrete graphics subsystem, have reduced autonomy and a higher level of performance, compared with the entry-level mobile PCs. At the same time, the cost significantly increases. It is at the heart of such computing systems that the GeForce 820M lies.

    The most productive notebooks are equipped with high-performance graphics accelerators. The cost in this case, they significantly increases, but autonomy is minimal. The hardware parameters of such computing systems allow solving any problems, including the most demanding toys of the latest generation.

Graphics Accelerator Specifications

GF117 - this is the code name for the graphics processor installed in theGeForce 820M. Characteristics it is indicated that it is based on an architecture codenamed "Fermi".The same semiconductor crystal is produced according to the standards of the 28-nm process technology. This discrete graphics system includes 96 shader modules, 16 blocksTMUand only 4 modulesROP.The clock speed of the video processor can vary from 719 to 954 MHz, and shader units, in turn, can operate from 1438 MHz to 1908 MHz. This video card implements proprietary technologyNVidiaentitledGPU Boost,which allows you to change the frequency of the graphics chip, depending on the degree of complexity solvedth  task and heating level of a semiconductor crystal.At the software level, technologies such asDirectX version 11.0 andOpenGL 4.5.


Memory subsystem

The basic equipment of this accelerator has 1 GB of RAM, and the more advanced version of GeForce 820M - 2 GB. Again, the availability of faster GDDR5 in this case is out of the question for the reason that this graphics chip is aimed at using DDR3. As a result, the RAM controller has lower frequencies in this case. Theoretically, in conjunction with such a video chip, you can use GDDR5, but the speed increase will be minimal. All the same, the bandwidth of the memory subsystem will be limited to the maximum value at the level of DDR3. The bit-width of the video buffer in this accelerator is 64 bits, and the memory frequency is 2000 MHz.

Thermal parameters

Thermal package in GeForce 820M is 15 watts. Accordingly, this graphic accelerator does not need an active cooling system and an additional power supply from the power supply side. But the majority of manufacturers nevertheless complete such laptops with active cooling. This is done taking into account the fact that such video cards are often overclocked and, as a result, an additional heat sink is needed.

Analogues

At once it is necessary to note that in terms of speedNVidia GeForce 820M surpasses the performance of any of Intel. For example, the HD Graphics Model 4400 is 2.5 times slower than the hero of this review. A slightly different situation with the products of the AMD company. Its hybrid processors are equipped with a powerful built-in graphics subsystem and the difference in this case is almost not felt. With discrete solutions from this manufacturer, the direct competitor is the Radeon model R7 M360. At a comparable level of cost, this graphics solution has a slightly higher speed. The performance level is equal to each other R7 M360 and GeForce 820M. They have very similar characteristics.
