There are few things that are more exciting in
the lives of computer geeks than the launch of a new generation of
video cards, and rightfully so, because every generation brings us
another shining example of Moore's Law at work, bringing us a leap
in performance, adding new features and lowering costs and sometimes
power consumption as well. ATI and Sapphire are hoping that
this generation is no different, bringing forward a slew of new GPUs
to attack the high end and midrange segments of the market.
Within the last couple of weeks, we have seen the Cypress-based
HD5870 and HD5850 completely blast the high end, and now we have the
HD5750 and HD5770 attacking the mid-range.
Which brings us to today, as Sapphire has sent us
a sample of their HD5770. This RV870 based beast uses the
previously mentioned Juniper core, which is essentially the
Cypress core cut in half, and should be in the same
ballpark as the RV770 based 4870 and 4890. Let's take a look
at the specs, shall we?
||ATI Radeon HD5770
||ATI Radeon HD5750
||ATI Radeon HD5870
||ATI Radeon HD5850
||ATI Radeon HD4890
As we can see from the above table, the HD5770 has
specifications that are nearly identical to the HD4890, except for
the 128-bit memory bus, 1.2GHz of GDDR5, and the new advanced TSMC
40nm process geometry. Some bonus specs and features:
DirectX 11 Support
ATI Eyefinity Technology, with support for
ATI Stream Technology
Windows 7 Support
2nd Generation TeraScale Engine
PCI-e 2.0 x16
HDMI 1.3 support with Deep Color and 7.1 High
Bitrate Audio, supporting bitstreaming for all Blu-Ray codecs,
including Dolby TrueHD and DTSHD-Master Audio.
On chip HDCP support
CrossfireX support for up to four discrete
cards on an AMD 790FX based motherboard
Avivo HD support for decoding HD video, Blu-Ray,
DVD Upscaling, and audio over HDMI
Dynamic power management for both core clocks
and memory clocks
While it is tempting to just gloss over the list,
it is important to point out that there are a couple very big
features that I am very excited to see, the top being the addition
of Dolby TrueHD and DTSHD-MA bitstreaming support. I just
can't wait to see a potential HD5650 come out in the near future for
me to throw into my HTPC.
The other big deal, is of course no secret.
Everyone has seen the Eyefinity demonstrations, and I am eager to
see how the support for this pans out in the coming months.
Gaming at 7680x1600 on three 30" monitors? Yes, please.
