ATI Mobility Radeon HD 5470: Specifications

Introduced in January 2010, the video adapter for mobile computers ATI Mobility Radeon HD 5470 was focused on the creation of mid-range computing systems. Such laptops, on the one hand, had quite good performance and without special problems coped with the most simple tasks. On the other hand, the availability of such discrete graphics allowed at that time to get high-quality "gameplay" in most toys, but with not the most maximum quality of the output image.

The market segment of this adapter

Very, very high requirements are advanced to mobile discrete graphics adapters. On the one hand, they must be highly energy-efficient. If this condition is not met, the autonomy of the device will be significantly reduced. On the other hand, their productivity should be at an acceptable level and even have a certain reserve. The laptop is bought for a long enough period of operation, and if you do not fulfill the last condition, it will quickly become obsolete. данной модели успешно применялись в сегменте ноутбуков среднего уровня в 2011 году. It was the harmonious combination of high energy efficiency and acceptable performance that was the basis of the ATI Mobility Radeon HD 5470. The Graphics Card of this model was successfully used in the mid-range notebook segment in 2011. It was this niche market of discrete mobile video cards that this solution was aimed at.

Technical specifications of the accelerator

² и содержал 292 миллиона транзисторных элементов. The advanced hardware specifications were in the ATI Mobility Radeon HD 5470. The characteristics of its processor indicated that its silicon crystal was produced using 40 nm technology, had an area of 59 mm ² and contained 292 million transistor elements. RV810 и имел кодовое имя Cedar . According to the manufacturer's nomenclature, it was designated as RV810 and had the codename Cedar . была фиксированной и имела значение 750 МГц. Its clock frequency was fixed and had a value of 750 MHz. PCI-Express в модификации 16Х и версии 2.1 . As the interface for connecting this video accelerator to the motherboard, PCI-Express in version 16X and version 2.1 should be used . Also in practice it was possible to meet laptops with versions of this interface 2.0 or 3.0, in which this video card was used. But it did not provide a special prize in terms of speed. In the first case, the accelerator mode automatically decreased to 2.0, and its performance decreased. In the second case, the resources of the motherboard were not fully used, and because of this, the performance of the computer system fell below its maximum capabilities. CrossFire. At the level of hardware specifications for this accelerator was announced support for CrossFire technology. That is, this accelerator could work in tandem with other adapters in this series, and due to this, the performance of the computer system should significantly increase.

ноутбуки с двумя дискретными ускорителями невозможно. In practice, it is impossible to meet laptops with two discrete accelerators. And as a result, this technology in the world of mobile computers has not received a significant spread. Shader blocks within the given video device were realized 80, and their frequency was 750 MHz, and they functioned synchronously together with the graphics processor. Rasterization modules for this accelerator were only 8 pieces. VGA ( максимальный формат картинки 1536х 2048) и два цифровых порта HDMI ( формат картинки — 1080р) и DVI (1600х2560). The list of supported video outputs with this accelerator included analog VGA ( maximum picture format is 1536x 2048) and two digital HDMI ports ( picture format - 1080p) and DVI (1600x2560).

Power consumption, temperature mode

The thermal package for the accelerator was declared at a level of 15 watts. Again, such a high value of power consumption did not allow using a passive heat sink system in combination with such an adapter. All the accelerators of this model were necessarily equipped with an active cooling system. The maximum value of the temperature for this semiconductor solution was set at 70 ^° C. Even in the most difficult modes of image output, this parameter did not exceed 62-65 ⁰ C. Only in the event of a breakdown of the cooler entering the cooling system could this emergency value.

Video buffer

это DDR3. The main type of RAM for ATI Mobility Radeon HD 5470 is DDR3. GDDR5, но подобная практика не получила особого распространения. Theoretically, his controller also allowed even GDDR5 to be used in conjunction with it , but this practice was not widely spread. The use of such an expensive component had an extremely negative impact on the cost of the mobile computing system, but it did not give much gain in terms of speed. The minimum size of the video buffer in this case was 512 MB, and the maximum - 1 GB. The recommended memory frequency was 800 MHz. The width of the video bus connection bus was 64 bits. подсистемы памяти такого видеоускорителя была заявлена на уровне в 25 Гбит/сек. The bandwidth of the memory subsystem of such a video accelerator was declared at 25 Gbit / s.

Comparison with representatives of previous generations of this manufacturer

HD4570 и HD3470 показывает существенный прирост быстродействия более свежего быстродействия. Comparison ATI Mobility Radeon HD 5470 with representatives of previous generations in the face of HD4570 and HD3470 shows a significant increase in the performance of more recent performance. The results of these three graphics accelerators in synthetic tests are given in the table below.

и HD3470 представлены ниже в таблице. The results of synthetic tests HD5470, HD4570 and HD3470 are shown in the table below.

Of all the values given, only the 2005 version of this test falls out. против 6925 баллов HD5470. 7846 points HD4570 against 6925 points HD5470. Most likely, the lower result of the latter is due to some flaws in the software.

Cost

In 2010, notebooks with such a video accelerator could be purchased for 600-800 dollars. In a new state, a mobile PC with such a video adapter can not already be purchased because the chip itself has become obsolete and out of production, and their stockpiles for the past six years have been sold out. But the processor RV810 can still be bought in a new state for repair of a failed laptop. Its price is in the range of 900-1400 rubles.

Drivers of video accelerator. Their features

The main operating system was for ATI Mobility Radeon HD 5470 Windows 7. It was under this and was released the latest version of the drivers for such software. There were also driver versions of this accelerator for Windows XP and Windows Vista. And for the previously mentioned three operating systems there were driver modifications for both 32 bit version and 64. In turn, for later versions of the system software in the face of Windows 8, 8.1 and the most recent 10 drivers for HD5470 were not released. Accordingly, under the control of such operating systems, the hero of this review could not function fully.

Reviews

A fairly balanced solution was ATI Mobility Radeon HD 5470. Reviews about it indicated that as a middle-class solution, it had no weaknesses. He had excellent energy efficiency and acceptable speed. At the same time, the price was appropriate. As a result, he had no significant shortcomings.

Summary

The balanced middle-level graphics accelerator was ATI Mobility Radeon HD 5470 6 years ago . At that time, its characteristics were relevant and allowed to solve any level of complexity of the task. But now this accelerator is outdated and has already moved to the entry-level solution segment.
