AMD's Radeon HD 5870: Bringing About the Next Generation Of GPUsby Ryan Smith on September 23, 2009 9:00 AM EST

Sometimes a surprise is nice. Other times it’s nice for things to go as planned for once.
Compared to the HD 4800 series launch, AMD’s launch of the HD 5800 series today is going to fall into the latter category. There are no last-minute announcements or pricing games, or NDAs that get rolled back unexpectedly. Today’s launch is about as normal as a new GPU launch can get.
However with the lack of last-minute surprises, it becomes harder to keep things under wraps. When details of a product launch are announced well ahead of time, inevitably someone on the inside can’t help but leak the details of what’s going on. The result is that what we have to discuss today isn’t going to come as a great surprise for some of you.
As early as a week ago the top thread on our video forums had the complete and correct specifications for the HD 5800 series. So if you’ve been peaking at what’s coming down the pipe (naughty naughty) then much of this is going to be a confirmation of what you already know.
3 months ago AMD announced the Evergreen family of GPUs, AMD’s new line of DirectX11 based GPUs. 2 weeks ago we got our first briefing on the members of the Evergreen family, and AMD publically announced their Eyefinity technology running on the then-unnamed Radeon HD 5870. Today finally marks the start of the Evergreen launch, with cards based on the first chip, codename Cypress, being released. Out of Cypress comes two cards: The Radeon HD 5870, and the Radeon HD 5850.
|ATI Radeon HD 5870||ATI Radeon HD 5850||ATI Radeon HD 4890||ATI Radeon HD 4870|
|Memory Clock||1.2GHz (4.8GHz data rate) GDDR5||1GHz (4GHz data rate) GDDR5||975MHz (3900MHz data rate) GDDR5||900MHz (3600MHz data rate) GDDR5|
|Memory Bus Width||256-bit||256-bit||256-bit||256-bit|
|Manufacturing Process||TSMC 40nm||TSMC 40nm||TSMC 55nm||TSMC 55nm|
So what’s Cypress in a nutshell? It’s a RV790 (Radeon HD 4890) with virtually everything doubled, given the additional hardware needed to meet the DirectX 11 specifications, with new features such as Eyefinity and angle independent anisotropic filtering packed in, lower idle power usage, and fabricated on TSMC’s 40nm process. Beyond that Cypress is a direct evolution/refinement of the RV7xx, and closely resembles its ancestor in design and internal workings.
The leader of the Evergreen family is the Radeon HD 5870, which will be AMD’s new powerhouse card. The 5870 features 1600 stream processors divided among 20 SIMDs, 80 texture units, and 32 ROPs, with 1GB of GDDR5 on-board connected to a 256bit memory bus. The 5870 is clocked at 850MHz for the core clock, and 1.2GHz (4.8GHz effective) for the memory, giving it a maximum compute performance of 2.72 teraflops. Load power is 188W, and idle power is a tiny 27W. It is launching at a MSRP of $379.
Below that we have the 5850 (which we will not be reviewing today), which is a slightly cut-down version of the 5870. Here we have 1440 stream processors divided among 18 SIMDs, 72 texture units, and the same 32 ROPs, with the same 256bit memory bus. The 5850 is clocked at 725Mhz for the core, and 1Ghz for the memory, giving it a maximum compute performance of 2.09 TFLOPS. With the disabled units, load power is slightly reduced to 170W, and it has the same 27W idle power. AMD expects the 5850 to perform at approximately 80% the performance level of the 5870, and is pricing it at $259.
Availability is going to be an issue, so we may as well get the subject out of the way. While today is a hard launch, it’s not quite as hard of a launch as we would like to see. AMD is launching the 5800 series with Dell, so it shouldn't come as a surprise if Dell has cards when e-tailers don't.
The situation with general availability is murky at best. The first thing we heard was that there may be a week of lag, but as of today AMD is telling us that they expect e-tailers to have 5870 cards on the 23rd, and 5850 cards next week. In any case whatever cards do make it in the channel are going to be in short supply, which matches the overall vibe we’re getting from AMD that supplies are going to be tight initially compared to the demand. So even after the first few days it may be hard to get a card. Given a tight supply we’ll be surprised if prices stick to the MSRP, and we’re likely to see e-tailers charge a price premium in the first days. Depending on just how high the demand is, this may mean it’ll take a while for prices to fall down to their MSRPs and for AMD to completely clear the backlog of demand for these cards.
Update: As of 5am EDT, we have seen the availability of 5870s come and go. Newegg had some in stock, but they have since sold out. So indeed AMD did make the hard launch (which we're always glad to see), but it looks like our concerns about a limited supply are proving to be true.
Finally, we asked AMD about the current TSMC 40nm situation, and they have told us that they are happy with it. Our concern was that problems at TSMC (specifically: yield) would be a holdup in getting more cards out there, but this does not look to be the case. However given the low supply of the cards compared to where AMD expects the supply to be, TSMC’s total 40nm capacity may not be to AMD’s liking.

Still no 3rd option for hd audio.
Has anyone been able to work this thing

no 3rd option for hd audio
otni - Sunday, November 29, 2009 - linkYES, WORKING PERFECT FOR ME...TRY THIS: PLAY THE BLUE-RAY MOVIE THEN GO TO SETTING ON POWERDVD AND CHARGES TO THE 3ER OPTION FOR HD SOUND.
IS WORKING FOR ME, THANKS CYBERLINK
FlyTexas - Saturday, November 14, 2009 - linkWhat good does it do to launch this, if there are still none for sale a month later?
Yes, I know there were a few sold up front, but NewEgg has been out for awhile...
RavnosCC - Tuesday, November 17, 2009 - linkThe 57xx series are readily available, they also support HD Audio.
RavnosCC - Monday, November 23, 2009 - link"As of today, new PowerDVD 9 Ultra customers will receive build 2320, which includes support for HDMI bitstreaming of undecoded (full quality) audio with ATI Radeon 5000 series graphics cards, and the Auzentech X-Fi Hometheater HD sound card. An update patch for current owners of PowerDVD 9 Ultra is scheduled to be available next Friday (11/27).
Qfromchicago - Wednesday, November 25, 2009 - linkThough happy that finally we will get hd audio using powerdvd, but why limit it to new customers only. It seems to me that if you can offer it to new customers, you should be able to offer it to everyone at the same time.
Qfromchicago - Sunday, October 18, 2009 - linkI have win 7, a diamond 5870, powerdvd 9 ultra version 2201 and still I don't get he 3rd choice for the HD audio bitstreaming. Has anyone been able to get bitstreaming to work with powerdvd 9. Thanks
RavnosCC - Thursday, November 5, 2009 - linkUPDATE: Looks like late November for the mythical patch...
Yes... we read these forums regularly. Feedback is forwarded to the appropriate people. These forums aren't the best way for us to provide customer support, so if you have an issue, please open a support ticket through our website.
We can't always comment on new developments... or at least we like to wait until we have a definite answer. I know everyone noticed the reviews for the ATI Radeon 5000 series graphics cards, where certain reviewers were using a pre-release version of PowerDVD 9 to demonstrate HDMI bitstreaming of Blu-ray audio. Support for this feature will be in the next PowerDVD update (patch), which will be available later this month. I don't have a firm date on this, but we're trying to expedite it. Please keep in mind that each of our regular updates includes fixes for new BD titles and new (or forthcoming) hardware / drivers across the PC ecosystem, and so the feature you are anxiously waiting for isn't the only thing that we need to include in the update. Of course, each update has to go through a full quality assurance testing procedure, to make sure that none of the changes introduced any new issues.
So... sorry for going quiet on you... but I and others read every post in this thread and other relevant threads, following up as needed (in some cases, directly through private messages on these forums).
RavnosCC - Wednesday, October 28, 2009 - linkI am in the same boat, with Vista, I have powerdvd 9 ultra fully patched and still no third option for hi-def passthrough... :-/
