The video card AMD Radeon HD 7670M. Rating of video cards for notebooks

Buying a laptop, many people think about how to get the greatest benefit in a technical specification for a lesser price. However, as practice shows, the numbers written on paper with characteristics do not always correspond to the present quality and performance of the notebook. Today we will talk about the "mobile" video card AMD Radeon HD 7670M, which can be found on many gaming computers of the economy class.

Are common

Let's start with the most basic characteristics. The video card AMD Radeon HD 7670M belongs to the classes of gaming and office graphics cards. This means that due to its technical capabilities it is able to launch most modern games, but not at the maximum settings.

It connects to the PCI-E interface x16, which ensures fast data exchange between it and the motherboard. The use of this video card (more precisely, its full model) is possible even in ordinary personal computers, but is not recommended because of low compatibility and performance in large systems.

By the way, it is worth paying attention to the process technology. The crystal size is as much as 40 nm, which testifies to the quite outdated technology. On most newer graphics cards this parameter is approximately 28 nm. In order to be better understood, we will clarify that this parameter is responsible for the cooling and clock speed of the device, so that the lower it is, the better not only for the user, but for the entire laptop as well, since there are no excessive overheating in resource-consuming applications.

Equipment

Now let's talk about the technical capabilities of the AMD Radeon HD 7670M. Characteristics responsible for performance and speed of computation, morally out of date four years ago, but still allow you to run the newest games on minimal settings.

The frequency of the graphics processor is 600 MHz, which, undoubtedly, is a very understated characteristic. On the other hand, this allows you to reduce heat dissipation, which means there will be less disruptions in the notebook.

The amount of video memory format GDDR5 is 2 GB. Yes, and with a frequency of 3600 MHz. When using the PCI-E connector, this provides a bandwidth of 57.6 Mbps. Not bad enough for a budget card, if not for the outdated 5D-architecture.

Thus, AMD Radeon HD 7670M serves as a good example of how a budget card, accessible to everyone, should look. On average, based on technical characteristics, it has a good potential and moderate heat release.

Mathematics

The next step in considering the AMD Radeon HD 7670M will be its computing unit. Most of the graphics card's performance will depend on these parameters. To better understand it, we will compare this device with a video card of the same price category, but for personal computers. Take for example Radeon R7 240.

The first parameter is the number of processors for calculating the color gamut and the geometric structure of the image. As you yourself understand, the higher this value, the faster the processing of the future picture. Here, of course, the AMD Radeon HD 7670M wins. The number of processors is 480 against 320 for R7.

Next come the blocks of textures and rasterization. And again, the 7670 wins, although not much. It has 24 and 8 blocks respectively, unlike 20 and 8 for R7.

But then it becomes more interesting. Although the degree of anisotropic filtering is the same for them, the R7 is capable of supporting newer standards, while the 7670M manages DirectX 11 and OpenGL 4.1. So, despite the fact that the video card we are considering has higher production capacities, it is not capable of supporting its relevance in modern systems.

Additionally

What else is worthy of mention when we speak about AMD Radeon HD 7670M? The characteristics of the video card, which we looked at, are obviously too high for such an old model. Therefore, the price for this performance has to pay a lot.

This video card occupies two slots in the laptop and requires a lot of space due to the need for additional cooling. Indeed, now it is difficult to meet a video card for laptops with a separate cooler designed for this purpose.

Moreover, the approximate amount of heat that must be dissipated is about 66 W. For a laptop, this can be fatal if you do not use additional cooling systems. If you are going to use a laptop with an AMD Radeon HD 7670M graphics card installed for games, then take the trouble to purchase additional cooling, for example a special stand with coolers.

Tests

How does this video card behave in practice? To compare it with modern game cards there is no sense, therefore the basic indicators were estimated, proceeding from realities of 2011.

3D performance should be similar to analogs with the same frequencies and the same structure. However, in practice it turns out that this video card periodically produces better results than HD 6730M, which itself is above the budget card. Of course, depending on the software, the tests can be very different, but the fact remains that in games of 2011 (the same age as the graphics card), the 7670M delivers maximum performance only at medium image detail settings.

Reviews

Any technical checks by professionals in the factory and the declared standards turn to dust when it comes to field testing. What difference does it make to what indicators the device issued on tests, if here and now it refuses to work fully? Let's turn to user feedback to better understand what is in the case of AMD Radeon HD 7670M. The feedback we submit will be left by users for the last 2 years, so the relevance of them is not lost yet. Let's start with the positive sides.

Most users note that the video card is working on cheers. In games until 2012 inclusive, high performance is noted even at high settings, which is very good for a budget video card. At the same time, with a certain skill, it is possible to run the newest games until 2016, at least on the "minimals". According to some statements, the same GTA 5 runs on ultra-high settings, but only if you completely sacrifice and turn off the shadows. In addition, this card is amenable to overclocking, which also allows using it in modern realities.

Negative

Despite the fact that the overwhelming majority of buyers are satisfied with their acquisition, there are always dark sides. It's the same with the AMD Radeon HD 7670M. The reviews carry relatively little negative information.

The first is, of course, overheating of the video card. Even at the stage of technical evaluation, we noted the outdated technology, because of which increases the heat released. Even the active cooling system on the board itself does not save.

The second is the performance in new games. In most cases, the overclocking of a video card saves , but it must be done with great care, all for the same reason of high temperature. In addition, there are several different models of this video card. If you are dealing with 512 MB of memory, then even overclocking will not help, but the model with 1024 MB just pulls the whole system.

The third dissatisfaction is related to the compatibility of this video card. Some users had a problem - the system refused to correctly recognize the parameters of the video card. It helped only to re-flash the BIOS to an older version. This means that people buying new laptops with such a card should be very careful. Perhaps they will not work at full capacity.

Summary

Today we told you about the AMD Radeon HD 7670M. Like most devices of the same price category, it can not boast of sky-high performance or performance, but it is quite capable of becoming a reliable "companion" for most modern laptops. Despite the low technical indicators, it gives good results in practice. And in most cases, the only thing that the user needs to take care of is additional cooling. If it were required to make a rating of video cards for laptops, then in the near 2011 it would rightly occupy the leading lines. However, now this is just another opportunity to save on the price of the device being purchased.
