Graphics adapter AMD Radeon HD 6670: features, comparison with competitors and the current product at the moment

In 2011, the niche of entry-level graphics cards was replenished with the AMD Radeon HD 6670. The characteristics of this accelerator were not revolutionary for budget-class products at that time, but certain engineering solutions allowed it to outstrip all possible competitors and come close to mid-range video cards. It is about this accelerator five years ago that will be discussed further.

For which market segment was this accelerator released

As it was mentioned earlier, the entry-level product was positioned by the manufacturer of AMD Radeon HD 6670. The characteristics and cost at that time of this accelerator were only confirmed. But in terms of speed and performance, it significantly exceeded its direct competitors for the reason that in this semiconductor crystal the total number of shader units and the frequency of the processor core were increased. At the current moment, this video accelerator for speed is still ahead of integrated accelerators and allows you to solve most of the tasks. The only thing that he will have problems with is the most demanding toys, which are very demanding for hardware graphics accelerator specifications.

Characteristics of the graphics chip

это кодовое название чипа, лежащего в основе AMD Radeon HD 6670. Технические характеристики его указывают на то, что он произведен по нормам 0,04 мкм техпроцесса. Turks is the code name for the chip underlying the AMD Radeon HD 6670. Its technical specifications indicate that it is manufactured at the standards of 0.04 micron process technology. аналогичной частоте, а их количество — 480 штук. The clock frequency is 800 MHz, and the shader processing modules in this case operate at the same frequency, and their number is 480 pieces. TMU, а блоков ROP в составе данного кристалла было всего 8. С позиции софта этот акселератор соответствовал спецификациям DX 11.0, OpenGl 4.1 и OpenCl 1.1. There were 24 TMUs on each pipeline , and only 8 ROPs in this crystal. From the software position, this accelerator conformed to the specifications of DX 11.0, OpenGl 4.1 and OpenCl 1.1. типа выходов можно было встретить на таких платах: Four types of outputs could be found on such cards:

• HDMI- версии 1.4. Digital HDMI version 1.4. The maximum resolution of it was 1920 * 1200 px.

• DVI. Another digital port is DVI. px*1600 px. In this case, the picture could be displayed in 2560 px * 1600 px. елителя сигнал можно было вывести одновременно на 2 монитора. Due to the special divider, the signal could be simultaneously output to 2 monitors.

• Display Port version 1.2. DVI, но возможности вывода изображения на 2 монитора при использовании этого интерфейса уже не было. The resolution in this case was identical to DVI, but the possibility of displaying the image on 2 monitors when using this interface was no longer there.

• VGA. Analog VGA port . px *1536 рх. Its maximum resolution was stated at 2048 px * 1536 px.

Thermal adapter specifications, temperature and power

The base power consumption for this accelerator was declared at 66W. 16Х равна 75 Вт, данный акселератор вполне мог обойтись и без системы дополнительного электроснабжения со стороны блока питания. Given that the maximum output power from the PCI-E 16X slot is 75W, this accelerator could well do without the system of additional power supply from the power supply side. But the majority of manufacturers with the purpose of increase of sales of the production dispersed the videocards, and in the recommended 75 W such accelerators simply simply did not fit. As a result, they were necessarily equipped with additional six-pin connectors.

Adapter memory subsystem

Under the use of GDDR5 was formalized RAM controller. But some manufacturers, in order to save and reduce the cost of products, completed such adapters with GDDR3 chips. Accordingly, it cost much less than a similar AMD video card Radeon HD 6670. The characteristics along with the performance in this case also significantly deteriorated and decreased. The size of the RAM interface in both cases was identical - 128 bits, but for GDDR5 the memory subsystem was operating at 4000 MHz, and for GDDR3 - only 1800 MHz. Due to this, the bandwidth of the video memory subsystem was dramatically different, which in the first case was 64 Gb / s, and in the second case it was 28 Gb / s. The amount of RAM in this case could be 1 GB or 2 GB.

Analogs and HD 6670 on their background

и GT430 были п рямыми конкурентами со стороны NVidia для AMD Radeon HD 6670. Характеристики всех этих трех ускорителей были весьма схожими. GT240 and GT430 were the direct competitors from NVidia for AMD Radeon HD 6670. The characteristics of all these three accelerators were very similar. But due to the increase in the number of shader processing units and the increased clock speed of the graphics processor core, the last accelerator left far behind its competitors. Crysis: Warhead в режиме 1280рх* 1024рх с максимальными настройками HD6670 выдавал 45-66 fps, а его конкуренты GT430 – 24-37 fps и GT240 – 32-48 fps. In the same Crysis: Warhead game in 1280px * 1024px mode with the maximum settings, the HD6670 gave out 45-66 fps, and its competitors GT430 - 24-37 fps and GT240 - 32-48 fps. Of these figures, one can clearly see that AMD's solution in this case is 1.5 times faster at a comparable level of cost.

Dirt 3 ( версия Colin McRae). A similar situation in the game Dirt 3 ( version of Colin McRae). 1050рх решение АМД выдавало 42-51 fps, а видеокарты Nvidia соответственно: GT240 – 31-39 fps и GT430 – 27-33 fps. In the 1680px * 1050px mode, the AMD solution produced 42-51 fps, and the Nvidia graphics cards, respectively: GT240-31-39 fps and GT430-27-33 fps. FPS для комфортной игры установлено на значении в 30. Как результат, решения Nvidia находятся на этой грани и могут не обеспечивать приемлемый геймплей, а у HD6770 есть определенный запас и за счет этого можно вполне комфортно на нем поиграть. The minimum number of FPS for a comfortable game is set at 30. As a result, Nvidia solutions are on this side and may not provide acceptable gameplay, while the HD6770 has a certain stock and due to this it is quite comfortable to play on it.

Adapter price to date

In an absolutely new state, such an accelerator can not be purchased right now. Such accelerators have already been removed from production, and stocks are sold in warehouses. You can buy such an adapter only in the market of second-hand components. At the same time, the price starts from 1500 rubles and ends at 4,000 rubles for the AMD Radeon HD 6670 Series. The characteristics of the video subsystem in this case play a key role in pricing. The minimum cost for accelerators with 1 GB of RAM and GDDR3 memory. Well, the maximum, as it is easy to guess, in models with 2 GB and GDDR5.

Results

In 2011, there were no real competitors from AMD Radeon HD 6670. The technical plan characteristics provided him with a higher level of performance. But now this accelerator has already come very close to the niche of integrated video cards. That is why it is not at the moment an actual graphic solution.
