AMD Radeon HD 6700 family of graphics accelerators was introduced in 2011. This group of devices included three models and was intended for the assembly of middle-class computers. Their parameters and specifications will be further considered.
Specialization
As previously noted, the Radeon HD 6700 series of graphics accelerators was designed to build mid-range computing systems. Moreover, in performance they were only marginally inferior to flagship accelerators. Moreover, their price was much lower.
The main area of use for such adapters is mid-range gaming PCs. Most games released in 2011 started without problems on such an accelerator. The only caveat is that in some cases the image quality will not be maximum.
Another possible area of application of these adapters is personal computers that specialize in processing graphic information. In this case, the computing resources of such an accelerator will also be quite sufficient for the implementation of the tasks. That is, as part of the graphics station, such video cards in 2011 also looked very decent.
Junior graphics accelerator model
The most affordable accelerator in the Radeon HD 6700 Series line is labeled 6750. It was based on the RV850 chip. This chip was produced using 40 nm technology. This microprocessor includes 720 graphic information processing units. Each of them operates at a fixed 700 MHz.
This adapter is mandatory equipped with GDDR5 memory chips that operate at a frequency of 4600 MHz. The nominal size of the video buffer for this accelerator is 1 GB. The width of the bus connecting the RAM to the microprocessor is 128 bits. All this ultimately allows you to get the bandwidth of the video buffer at 73.6 Gb / s.
Middle class accelerator
A higher level of performance in the AMD Radeon HD 6700 line was provided by the model marked 6770. It was also based on the RV850 chip, which had identical technical specifications. But clock speeds provided a high speed of processing graphic images. The microprocessor itself in this case was already operating at 850 MHz, and the memory at 4800 MHz. Actually, due to such a simple solution, a higher performance of this graphic subsystem was provided. In percentage terms, the increase in speed was 10-15%. But at the same time, the cost of this discrete accelerator proportionally increased by all the same 10-15%.
The most productive adapter in this family
The fastest graphics solution of the Radeon HD 6700 family was labeled 6790. In this case, the adapter was based on the Barts microprocessor. It was manufactured using a similar technology, but it already included 1,700 million surface transistors. It included 800 stream processors that worked at a frequency of 840 MHz.
This GPU also included 40 TMUs and 16 ROPs. The volume of the video buffer was 1 GB. Moreover, all the same GDDR5 chips were used, which worked at a lower frequency of 4200 MHz with respect to HD 6770. The key feature of this accelerator is the increased bit capacity of the RAM connection bus, which in this case was 256 bits. Due to this, the bandwidth of the RAM of this accelerator was 134 Gbit / s compared to 76 Gbit / s for the HD 6770. Therefore, this adapter already had a 30% advantage over the mid-range device.
Conclusion
The key drawback of the Radeon HD 6700 series of graphics accelerators is that they are out of date. Indeed, such adapters were introduced over 5 years ago. During this time, the world of computer components has changed dramatically and the model range of AMD accelerators has been updated quite often. Therefore, now such devices can be classified as entry-level solutions with low performance.
