The Intel Celeron 847 processor unit is universal. It can be found both in low-speed laptops and in economy class desktop systems. A key feature of this CPU model is its low power consumption, due to the technical parameters of the chip, so the microprocessor can do without an active cooling system.
Positioning and possible use cases
As previously noted, Intel Celeron 847 can be found both as part of the system units of personal computers and laptops. In any case, such computing systems have a low level of performance and are aimed at implementing the most simple software tasks. The latter include office packages and browsers that are undemanding to the hardware specifications of the game. The chip allows work in the simplest graphic editors, for example, Paint or Paint.Net. In addition, the PC allows you to play audio files and videos. In the latter case, the resolution of the picture should not exceed HD.
CPU Features
Characteristics Intel Celeron 847 attribute this CPU to the Sandy Bridge generation, that is, this is the second revision of the Core architecture. The composition of this chip includes two separate blocks for processing software instructions. Each of them operates at a frequency of 1.1 GHz. The microprocessor should be nominally installed in the BGA1023 connector, but most manufacturers minimized the cost of such low-performance PCs, so it was soldered directly to the system board.
The thermal package of the semiconductor device is limited to 17 W and this CPU can function in combination with a conventional passive cooling system. The crystal manufacturing technology of this processor complies with 32 nm standards. The highest chip heating temperature is 100 ° C.
This microprocessor is equipped with an impressive cache size, which is divided into three parts. The first of them has a capacity of 128 kb, the second - 512 kb and the third - 2 MB. An integrated RAM controller is located on the same substrate as the computing modules. According to specifications, it operates in dual channel mode and is aimed at working in tandem with DDR3 memory. The maximum volume of the latter is 16GB.
Graphics Accelerator
The Intel Celeron 847 processor is equipped with an integrated graphics adapter - HD Graphics. This is a stripped-down version of a more productive accelerator with an index of 2000. This video card can display a picture simultaneously on two screens. Its computing units dynamically change their frequency, which can vary from 350 to 800 MHz. To store the processed information, this accelerator uses part of the system RAM. The amount of video buffer can be set in the BIOS.
Performance
We will evaluate the performance of the Intel Celeron 847 CPU using the example of the MSI C847IS - P33 motherboard. It is designed to build compact PCs in a Mini-ITX package. The competitors of the hero of this review were E - 350 from AMD (AsRock E350M1 motherboard), ATOM D2700 (Intel D2700DC) and Celeron G1610 (Z77IA-E53 from MSI). The last two CPU models are Intel devices.
At the first stage, testing was carried out in the PCMark'7 package. In this case, computing systems were able to produce the following results:
- Celeron G1610 - 3429.
- Celeron 847 - 2164.
- AMD E-350 - 1613.
- ATOM D2700 - 1463.
The G1610 microprocessor has higher clock speeds and the most advanced architecture, which is why it shows the highest result. The hero of this review lags significantly behind him. Its architecture is identical with the leader of this test, but the frequencies are reduced and energy efficiency is improved. This is due to its lag. But the E-350 and D2700 are hopelessly behind. They have a small cache and outdated architecture.
The next test was conducted in Photoshop CS5. Within its framework, 4 pictures were processed in a resolution of 10 megapixels. The following time was taken in seconds to complete this operation:
- Celeron G1610 - 152.2.
- Celeron 847 - 377.6.
- ATOM D2700 - 490.7.
- AMD E-350 - 544.7.
The winner has not changed - G1610, due to the higher frequency of his work. The second place is occupied by an energy-efficient representative of this Celeron 847 series. Outsiders have switched places, but they have a comparable result.
Relevance and reviews
The Intel Celeron 847 is still able to cope with the initially assigned tasks, so it is too early for owners of such computers to think about upgrading and updating, but it is no longer advisable to buy a new PC based on such a CPU. There are more modern similar solutions.
The advantages of the hero of this review, the owners include speed, energy efficiency and low cost. This processor has one minus - it is outdated at the moment.
Conclusion
In this article, the microprocessor of the Intel Celeron 847 model was considered. Its key feature was reduced power consumption. The main area of its use is computers with low performance, both desktop and mobile.
