At the time of the release of the HD 5700 series video cards, they could no longer be called the best. This series was intended for the mass buyer, and AMD thus simply continued to fill the niche of video chips with support for DirectX 11. In fact, the cards in this series should become cheaper analogs of the HD 5800 version. This conclusion can be drawn from the characteristics of the ATI Radeon HD 5700 Series. Only two cards were included in this series: these are HD 5770 and HD 5790. There was also a video card HD 5830, which would be logical to rank as ATI Radeon HD 5700 Series. Its characteristics were consistent with this series, and it should have had a "name" HD 5790, but the developer ranked it as another series due to the 256-bit memory bus and another GPU.
ATI Radeon HD 5700 Series Features
Given that there are two video cards in the series, let's start with the younger model. The reference model HD 5750 operates at a frequency of 700 MHz, and the GPU has 720 universal processors. The older HD 5770 graphics card is different for the better: here the processor frequency is 850 MHz, and the number of processors is 800.
Before the release of both video cards, there were rumors that they would get a memory operating at the same frequencies, but in fact the frequencies are slightly different. The younger model has a memory frequency of 1150 MHz, and the memory frequency of the older model is 1200 MHz. This means that the latter will be slightly faster, although the difference is very small. The GDDR5 memory of both cards is 1024 MB, and the memory bus is 128 bits. This clearly can not be attributed to the list of advantages of models.
The main competitors of the HD 5750 video card are either the GTX 260 from the manufacturer Nvidia or the HD 4890 video card. However, the latter is a little faster, because in the 3DMark performance test the 5770 card scores 9103 points, and the older HD 4890 graphics gets a score of 10312 points.
Cost and overclocking characteristics of the ATI Radeon HD 5700 Series
In this line, the HD 5770 card turned out much better than its younger version. Its price in Moscow averages 4000 rubles. Although today this model is no longer manufactured and it is impossible to find it on sale. Note that the adapter has established itself as a fairly cold and quiet solution with high performance. And if you buy this video card from third-party partner partners with an improved cooling system, you can generally get complete silence from the system unit even when you launch quite “heavy” 3D applications.
If you overclock this board a little with a good cooling system, it can even catch up with the performance of HD 5830. And if you use 2 HD 5770 graphics cards in tandem using CrossFire X technology, you can get a big increase in performance.
About the HD 5750 Card
As for the HD 5750 in the ATI Radeon HD 5700 Series, its performance is worse than the older model. Although the performance almost did not drop compared to the HD 5770 card, the model turned out to be quite hot and loud. It was very hot, and its cooling required high speeds of rotation of the cooler. Most likely, the cooling system was extremely unsuccessful, but there are partner video cards with their cooling systems. Perhaps they are not noisy.
However, despite the lower characteristics of the ATI Radeon HD 5700 Series (HD 5750) video card, it can achieve the performance of the HD 5770 model when overclocked. This means that the buyer can get approximately the same performance for the same money. But, frankly, the heat and noise of the youngest in the line of the video card scared off many buyers who learned about these shortcomings from forums on the Internet.
Conclusion
At the time of release, both cards were positively received by the public. For relatively little money, you could buy a card that supported modern technology and allowed you to run game releases at maximum settings. At the same time, these cards were never TOP cards, and today they are obsolete. By modern standards, the technical characteristics of the ATI Radeon HD 5700 Series are rather weak for 3D applications (games). However, such cards are found in old office computers or laptops (mobile versions are used there), which are suitable for surfing the Internet and office tasks.
