Graphics card AMD Radeon HD 7670M. Ranking of graphics cards for laptops

Buying a laptop, many people are thinking about that for a lower price to get the greatest benefit in the specifications. However, as practice shows, numbers, written on paper with characteristics not always correspond to present quality and performance of the laptop. Today we will talk about "mobile" graphics card AMD Radeon HD 7670M, which can be found on many gaming computers in the economy class.

General

Let's Start with the most basic characteristics. Graphics card AMD Radeon HD 7670M belongs to the classes of gaming and office cards. This means that thanks to its technical features it is able to run most modern games, but not at maximum settings.

It connects through the PCI-E x16, that provides fast data exchange between it and the motherboard. The use of this card (or rather its model) is possible even in ordinary personal computers, but is not recommended due to low compatibility and performance for large systems.

By the Way, you should pay attention to the process. The size of the crystal is as much as 40 nm, which is indicative already of a rather outdated technology. On most newer graphics cards this option is approximately 28 nm. To better understand, explain - this parameter is responsible for cooling and the clock speed of the device so that the lower it is, the better not only for user but also for the entire notebook as a whole, since the processor-intensive applications does not occur excessive heat.

Technique

Now let's talk about the technical capabilities of the AMD Radeon HD 7670M. Characteristics responsible for the performance and speed of computation are obsolete even 4 years ago, but still allow you to run on minimum settings most new games.

The Frequency of the graphics processor is 600 MHz, which, no doubt, is a very underestimated feature. On the other hand, this reduces the dissipation, and hence the malfunction of the laptop will be less.

The Amount of video memory GDDR5 2GB. So even with a frequency of 3600 MHz. When using PCI-E this provides a bandwidth of 57.6 Mbps. Quite good performance for a budget card, if not obsolete 5D-architecture.

Thus, AMD Radeon HD 7670M is a good example of how should look like a budget card, available to everyone. On average, based on the technical specifications, it has good potential and moderate heat.

Mathematics

The Next step in the review AMD Radeon HD 7670M will be her computing unit. A large part of the graphics performance will depend on these parameters. To better to understand, we compare this device with the graphics card in the same price category, but for personal computers. Take for example the Radeon R7 240.

The First parameter is the number of processors for the calculation of the color and geometric structure of the image. As you know, the higher the value, the faster processing of future image. Here, of course, wins AMD Radeon HD 7670M. The number of processors is 480 vs 320 at R7.

Followed by blocks of textures and rasterization. And again 7670 wins, though not much. It has a 24 and 8 units, respectively, in contrast to the 20 and 8 at R7.

But then it becomes more interesting. Despite the fact that the degree of anisotropic filtering is the same, R7 is able to support newer standards, while costs 7670M DirectX 11 and OpenGL 4.1. So, despite the fact that we are considering video card the above production capacity, it is not able to maintain its relevance in the modern systems.

Details

What else is worthy of mention when we talk about AMD Radeon HD 7670M? The characteristics that we considered, clearly too high for such an old model. So the price for this performance has to pay a lot.

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

The more that the approximate amount of heat which must be dissipated is about 66 watts. Laptop it can be fatal if not using the additional cooling system. If you are going to use the laptop with an installed graphics card AMD Radeon HD 7670M for games, then take the trouble to buy additional cooling, for example a special stand with coolers.

Tests

Behaves Like this card in practice? Compare it to modern gaming cards there is no point, therefore, the main indicators were estimated, based on the realities of 2011.

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

Reviews

Any technical checks by professionals at the factory and the stated standards crumble to dust when it comes to field trials. Who cares what indicators were given the device to test, if here and now it refuses to work? Let's turn to user reviews to better understand what is in the AMD Radeon HD 7670M. Reviews that we present are left by users during the last 2 years, so the relevance is not lost. Let's start with the positives.

Most users say the video card works great. In games up to 2012 inclusively, is high performance even on high settings, which is very good for a budget graphics card. At the same time at a certain skill has the ability to run most new games until 2016 at least "the minimum salary". According to some, the same GTA 5 runs on ultra-high settings, but only if you completely sacrifice it and turn off shadows. In addition, this card lends itself to overclocking, which also allows its use in modern realities.

Negatives

Despite the fact that the vast majority of buyers satisfied with their purchase, are always the dark side. Similarly, in the case of AMD Radeon HD 7670M. Reviews are relatively few negative information.

The First is, of course, overheating of the graphics card. At the stage of technical evaluation, we noted outdated technology, which increases heat. Do not save even the active cooling system on the card.

The Second is the performance in new games. In most cases, saves the overclocking, 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 card. If you have 512 MB of memory, then it will not help even acceleration, but the model with 1024 MB of just stalling the entire system.

The Third frustration is related with the compatibility of this card. Some users have discovered a problem - the system refused to properly recognize the graphics card. Helped only flashing the BIOS to an older version. This means that people buying new laptops with this card have to 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 in the same price category, it could not boast of sky-high performance or performance, however, is quite capable to become a reliable "friend" for most modern laptops. Despite the low technical indicators it gives good results in practice. And in most cases the only thing you need to take care of the user is additional cooling. If I had to rank graphics cards for laptops, in the near 2011, she would rightfully holds the leading strings. However, now it is just another opportunity to save on the price of the purchased device.
