Today, AMD announced a new video card ATI Radeon HD 5670. As in most cases, the emergence of new items was not a surprise to us. Even before the announcement of unofficial sources “sprayed” web rumors about the characteristics of the accelerator, which is worth noting, largely confirmed. In addition, there were even published a comparative test results against the Radeon HD 5670 Radeon HD 4670.
So, ATI Radeon HD 5670 is the world’s first DirectX 11-compatible graphics accelerator in the price category up to $ 100. Chip is made on the basis of the advanced 40-nm process technology, includes 627 million transistors, 400 stream processors, 20 texture units, 8 raster operation units (ROP), operates at a clock frequency of 775 MHz and has the computing power of 620 GFlops. The detailed structure of the chip is shown in the figure below.
There are two versions of the accelerator – with 512 MB and 1 GB of GDDR5-memory. The memory is clocked at 1000 MHz (effective frequency of 4 GHz), and its bandwidth is 64 Gbps. From the interfaces in the picture we see the reference sample D-Sub, DVI, HDMI. Typical power consumption innovations is 61 watts, and idle power is reduced to 14 Tues
Because technology is supported noteworthy ATI Eyefinity, which allows you to organize multiple monitors. In the ATI Radeon HD 5670 is implemented to simultaneously connect up to four monitors. Thanks to technology ATI Stream when playing flash videos in Adobe Flash player to 50% reduced load on the CPU, and significantly accelerated transcoding video CyberLink Espresso.
Unfortunately, samples of the new cards, which were intended for our test lab, were delayed at customs. Therefore, the article with conclusions about the performance of Radeon HD 5670 will be released later.
Finally, we note that in February, AMD plans to release several new products – boosters series Radeon HD 5500 and Radeon HD 5400. Decisions Radeon HD 5500 Series will be implemented in low-profile form factor and focus on the computers of small size and HTPC-system. They will also support DirectX 11, ATI Eyefinity (up to three monitors) and have low power consumption – less than 50 watts. From features Radeon HD 5450 indicated the possibility of producing solutions with passive cooling.
