The network has a preliminary review of future graphics chips from AMD Radeon HD 5700 series, and the source of published specifications Juniper on this "grab-bag. Analyzing these data, it should be borne in mind that before the official announcement of the new processors, these characteristics may change.

Thus, the chip HD 5750, reference video which shows the top picture, will work at a frequency of 700MHz, the chip HD 5770 will work on 850MGts (some sources report 825MGts). GPU Radeon HD 5750 will have 720 universal processors, while the HD 5770 to be 800 units.

Earlier there were rumors that the HD 5750 and HD 5770 are identical to the frequency of memory, but according to available data, the memory on graphics cards with HD 5750 will operate at a frequency 1150MGts, while the memory cards in the HD 5770 will be 1200 MHz, ie at 50MHz faster. This is not a very serious differences, which, nevertheless, worth noting. In addition, in the future will be HD 5750 with 512MB of memory, but the official announcement will be presented only version of HD 5750 and HD 5770 with 1024MB of memory GDDR5. By the way, again according to rumors, the memory interface is 128-bit, which can hardly be attributed to a number of merits for future graphics cards.

Announcement scheduled for Oct. 13. According to some experts, Radeon HD 5770 almost as fast as HD 4890 or GTX 260 from nVidia, and in doing so will cost just over € 130 per party of 100 pieces, which will cause some headaches for nVidia. Video Cards on-chip Radeon HD 5750 should meet the range from € 110 to € 120 in the batch of 1000 pieces, but about the performance of this chip yet unknown.

In addition to the expected characteristics of the new graphics chips in the network appeared photography video Asus Radeon HD 5770 and the results of the same test. This video was made based on the reference design ATI, its printed circuit board is somewhat shorter than the HD 5850, and the board has a 6-pin power connector. On board there are 8 chips Hynix GDDR5, GPU core is 850MGts, the memory frequency is 1200 MHz. Connect this card to different devices, possibly through the two ports, DVI, and also through the HDMI and DisplayPort.

When testing the video card Asus Radeon HD 5770 in 3DMark Vantage has achieved results P9103, while HD 4890 was P10312. Maximum temperature of GPU HD 5770 reached 83 ° C, although the ambient temperature remained under the cloak of secrecy. In addition to the HD 5770 for comparison were tested on the video chip ATI Radeon HD 4890, nVidia GeForce GTX 260 and the nVidia GeForce GTX 275.
