NVIDIA GeForce 820M - model review, customer reviews and expert reviews

GeForce 820M. The discrete graphics accelerator of the middle class for mobile computers is the GeForce 820M. This 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:

1. Mobile systems of the entry level with a minimum level of speed, 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.

2. 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.

3. 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

это кодовое обозначение графического процессора, установленного в GeForce 820M. GF117 is the code name for the graphics processor installed in the GeForce 820M. Its characteristics indicate that it is based on an architecture codenamed "Fermi". The very same semiconductor crystal is produced according to the standards of the 28-nm process technology. , 16 блоков TMU и лишь только 4 модуля ROP. Such a discrete graphics system includes 96 shader modules , 16 TMUs and only 4 ROP modules . The clock frequency of the video processor can vary in the range from 719 to 954 MHz, and shader units, in turn, can operate from 1438 MHz to 1908 MHz. NVidia под названием GPU Boost, которая позволяет изменять частоту графического чипа в зависимости от степени сложности решаемо й задачи и уровня нагрева полупроводникового кристалла. In this video card NVIDIA proprietary technology called GPU Boost is implemented , which allows changing the frequency of the graphics chip depending on the degree of complexity of the task and the level of heating of the semiconductor crystal. Direct Х версии 11.0 и OpenGL 4.5. At the software level, technologies such as Direct X version 11.0 and OpenGL 4.5 are supported .

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 a faster GDDR5 in this case is out of the question for the reason that this graphics chip is aimed at the use of 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. Still, 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

The thermal package in the 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

NVidia GeForce 820M превосходит по производительности любую интегрированную видеокарту от «Интел». At once it is necessary to note that NVidia GeForce 820M outperforms any integrated video card from Intel in terms of performance . 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 integrated 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 performance. The performance level is equal to each other R7 M360 and GeForce 820M. Their characteristics are very similar.

Reviews about the graphic card

Of course, at the maximum settings, all the most demanding toys will not draw GeForce 820M. Reviews this only confirm. But do not forget that this is a mid-level solution. Therefore, the performance is at an average level, the price in comparison with the notebooks of the entry level is higher, and the autonomy is slightly worse. Such mobile personal computers perfectly combine acceptable speed and good autonomy. If you need autonomy, then choose a less expensive laptop with an integrated graphics card, and if you need maximum performance - we buy a more expensive mobile computer with uncompromising speed.

Results

это отличный видеоадаптер для ноутбуков среднего уровня. GeForce 820M is an excellent video adapter for mid-range notebooks. They, on the one hand, allow most toys to run, but on the other hand, they have a good autonomy and very affordable price. It is this combination that makes such PCs in this niche one of the best.
