ATI is launching their Juniper series of cards today, with two cards, the 5770 and the 5750. The 5770 has 800 Stream Processors, the same as on the HD 4890 and HD 4870 cards that were the top of the line until the HD 5870 and HD 5850 launched. The number of ROPs and TMUs remains the same from the HD 4890.
One key difference is the memory interface. While the HD 4890 had a 256-bit memory interface with GDDR5 memory, the HD 5770 has a 128-bit memory interface with GDDR5 memory. The memory clock on this card is 1200MHz, or 4.8GHz effective, giving a memory bandwidth of 76.8GB/second on the HD 5770. This is less than the 115.2GB/second on the HD 4870 but it is targeted for the mainstream market, not the high-end.

The key new feature of the HD 5 series is the support for Microsoft DirectX 11. DirectX 11 adds support for Hull Shaders, Compute Shaders and advances to the other Shaders in terms of program length and complexity. DirectX 11 is set to be released with Microsoft Windows 7 on October 22nd, making this the perfect time to launch a DirectX 11 card. ATI released the HD 5870 for the high-end ($379), HD 5850 ($279). Today they are launching two new cards to support it the HD 5750 and HD 5750.
Eyefinity is ATI’s trademark for their new multi-display technology. At their launch event in San Francisco ATI showed off a 24 monitor display showing off four HD 5870s with six Display Ports on each card driving 24 monitors. The reference HD 5770 has three monitor outputs via a DP, a HDMI and a Dual-Link DVI that can be used for up to three monitors with the DP and two DVIs used to accomplish that feat. Note you can also attach adapters to the ports to connect VGA or DVI monitors to the HDMI port.
The HD 5750 card is a little bit different and designed for a little lower price. The card has 720 Stream Processors and is akin to half a HD 5850 in terms of ROPs, TMUs and the like with 36 texture units and 16 ROPs. In terms of performance the HD 5750 should be lower than the HD 5770 as the clock speed and memory bandwidth is less than the HD5770. The memory interface is also 128-bit GDDR5 memory but clocked at a lower 1150MHz giving 73.6GB/second of memory bandwidth. The HD 5750 also supports all of the DirectX 11 features, Eyefinity and the other HD 5xxx series features.
