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.

Today’s Launch

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
Stream Processors 1600 1440 800 800
Texture Units 80 72 40 40
ROPs 32 32 16 16
Core Clock 850MHz 725MHz 850MHz 750MHz
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
Frame Buffer 1GB 1GB 1GB 1GB
Transistor Count 2.15B 2.15B 959M 956M
Manufacturing Process TSMC 40nm TSMC 40nm TSMC 55nm TSMC 55nm
Price Point $379 $259 ~$180 ~$160

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.

    I think that you're missing the point. AMD appeared to want the part to be small enough to maximize the number of gpu's generated per wafer. They had their own internal idea of how to get a good yield from the 40nm wafers.

    It appears to be similar to their line of thinking with the 4870 launch (see http://www.anandtech.com/video/showdoc.aspx?i=3469">http://www.anandtech.com/video/showdoc.aspx?i=3469 for more information) - they didn't feel like they needed to get the biggest, fastest, most power hungry part to compete well. It turns out that with the 5870, they have that, at least until we see what Nvidia comes out with the G300.

    It turns out that performance really isn't all people care about - otherwise nobody would run anything other than dual GTX285's in SLI. People care about performance __at a particular price point__. ATI is trying to grab that particular sweet spot - be able to take the performance crown for a particular price range. They would probably be able to make a gargantuan low-yield, high power monster that would decimate everything currently available (crossfire/SLI or single), but that chip would be massively expensive to produce, and surprisingly, be a poor Return on Investment.

    So the comment that Cypress is "too big" I think really is apropos. I think that AMD would have been able to launch the 5870 at the $299 price point of the 4870 only if the die had been significantly smaller (around the same size as the 4870). THAT would have been an amazing bang-for-buck card, I believe.

    Ryan is updating the page now. He should be finished up shortly. We had a lot of images that needed to be displayed in a different manner at the last minute. Reply

    You very clearly fail to mention that the cheapest GTX295 one can buy is nearly $100 more expensive than the HD 5870. Reply

    In my own defense, when I wrote that paragraph Newegg's cheapest brand-new GTX 295 was only $409. They've been playing price games... Reply
  • SiliconDoc - Friday, September 25, 2009 - link

    That "price game" is because the 5870 is rather DISAPPOINTING when compared to the GTX295.
    I guess that means ATI "blew the competition" this time, huh, and NVidia is going to get more money for their better GTX295.
    LOL
    That's a *scowl* "new egg price game" for red fans.
    Thanks ATI for making NVidia more money !

    lol, did they drop the price while they had 5870s in stock, then raise it again once they were gone? Reply
  • SiliconDoc - Wednesday, September 23, 2009 - link

    Oh, so sorry, 1:46pm, NO 5870's available at the egg...
    I guess they sold 1 powercolor and one asus...
