AMD's Radeon HD 5870: Bringing About the Next Generation Of GPUs

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.

Oh really ? Now wait a minute, spin master. When the site here whined about "paper launch" it was Derek who brought up a two or three year old nvidia card, and cried and whined about it. Then speculated the GTX275 was paper, and then "a phantom card".Well, that didn't happen.... no apologies about it ever either.
---
The PAPER launches of late are ATI ATI ATI ! ! !
We have the 4770, and now this one !
----
Gee, when ATI BLOWS IT, we suddenly talk in vague terms about "the companies" having "papery launches" as " the general rule of thumb of how it's done.." - and that makes us "not a fan boy!??!"
R0FLMAO !!!!
Yes, of course, since the red ati is bleeding paper launches and the last one from nvidia one can actually cite is YEARS AND YEARS ago, yes, of course, you're correct, it's "unnamed companies in the multiple" that "do it"....
---
I swear to god, I cannot even believe the massive brainwashing that is a gigantic pall all over the place.
---
If I'm WRONG, please be kind, and tell me what nvidia paper launches I missed.... PLEASE LET ME KNOW.

Is\was a good idea to shoot for as this is most certainly what Nvidia is going to attempt to achieve. But I am a bit disappointed this care rarely achieved it.I do like angle independent AF though. Should be interesting to see what Nvidia brings to the table. But kind of like the CPU situation(i5) I am kind of meh. But will say this has more potential compared to its predecessor than the i5 series does compared to Core 2 Duo.

I thought that was just great, those pretty pictures, and then I get to reading. I see the 4890 and SQUARES. I see the GTX285, with CIRCLES and an outer rounded octagon.Then the 5870- and it's "perfectly round" angle independent algorithm, but I still see some distortions.
--
So I get to reading and am told "the 4890 and 285 are virtually the same". I guess the wheel was first made square, and rolled as well as when it became round. No chance the reviewer could tell the truth and remark that NVidia has the best, until today.. NOPE can't do that!
---
Then, of course, the celebration for the "perfection" of the 5870 and ATI's superb success in the "round" category...
EXCEPT:
We get to the actual implementations and NO PERCIEVED DIFFERENCE IS VISUALLY THERE. It cannot be seen. The article even states they searched in vain for some game to show the difference. LOL
All that extra effort to for pete sakes show that ATI superiority...all WASTED EFFORT, but for red roosters I'm certain it was a very exciting quest, titillating, gee a change to take down big green...
---
So bottom line is IT'S A BIG FAT ZERO, even the older, worse ati implementation is apparently "non distinguishable".
It is remarked that NVidia doesn't "officially" support this method in game, and of course, after much red rooster effort, one finds out why.
THERE IS NO DIFFERENCE in visual quality. Another phantom red "win".
Another reason NVidia makes money (why waste it on worthless crap in developement that makes no difference), while ATI does not.
Yeah, that was so cool.
So happy the "mental ideation of perfection in the card for ati fans" was furthered. ROFL

A quick question. Why is there no 5850 review available atm?1> Was there a separate NDA for the 2 cards?
2> Were there no sample cards given by AMD to reviewers?
3> Did AMD ask reviewers to postpone said reviews due to market supply problems/glitches?
4> Was this a strategy decision by AMD, for marketing or other reasons?
Ryan Smith - Wednesday, September 23, 2009 - link
AMD only provided us with 2 5870s, the 5850 was not sampled. 5800 series cards are in short supply, even for reviewers.Dante80 - Thursday, September 24, 2009 - link
Thank you for the prompt answer, that was what I was guessing too. Cheers...^^Spoelie - Wednesday, September 23, 2009 - link
To get enough 5870 cards in the channel for a hard launch, they used every possible die.There are probably not enough harvested dies to create the 5850 line just yet. And they're not gonna use fully functional ones that can go in a 5870 when supply for them is tight already.
Once the 5850 is launched, demand for them is up and yields matured, they'll have to use fully functional dies to keep supply up, but now they're building up inventory for a hard launch during the coming weeks.

Uhh, just a minute there feller. The SOFT or PAPER LAUNCH has already hit, the big LAUNCH DATE is today....Newegg is a big ZERO available... (one Powercolor was there 30 mins ago, the other 3 listed are NOT avaailable, I watched them appear last night).
---
So, when Ati has a "hard launch" they get "many weeks after the launch date" to "ramp up production" and "fill the need".
ROFLMAO
I was here when this site and the red roosters whined about Nvidia and appear launches, and I believe it was the GTX275 that was predicted to be PAPER (not very long ago in fact) here, and the article EVEN SPECULATED IT WAS A PHANTOM CARD.
All the red roosters piled on, but.... the card was available on launch, it wasn't a PHANTOM, and all that bs was quickly forgotten and shoved into the memory hole like it never happened...
---
Oh, but when it's ATI and not Nvidia, the 4770 can remain almost pure paper near forever, and this one, golly it can be 95% paper and it's just " getting ready for a hard launch" WEEKS BEYONDS the launch date!
ROFLMAO

No bias here?!? "Where's da' bias?!?!" said the red rooster (to the green goblin)...
Give me a break.

Just because you can't find it in the states doesn't mean it's a fake launch. And fake launch? What are you a 12 year old or something? You're like the nvidia version of snakeoil. Just go play with your nvidia part m'kay ?SiliconDoc - Sunday, September 27, 2009 - link
Well, since you insulted, and mischaracterized, I came across the reminder about the 4870 paper launch.Yes, that's correct, this is how ATI rolls, a big fat lying launch date, a piddle of a few cards, then wait a couple weeks or a month.

" The cards are fast, but as many pointed out HD 5870 is not faster than Geforce GTX 295, which is something that many have expected. Radeon 5850 will also start selling in October time, but remember, last summer when ATI launched 4870, the card was almost impossible to buy and weeks if not months after, the availability finally improved. "

Like I've kept saying, the bias is so bad... I keep discovering more big fat ati blunderous moves, that are instead ascribed to imaginarily to Nvida.
Thanks for the incorrect whining, anger, and standard PC e-mindless chatroom repeated, non original, heard ten thousand times, brainless insult, it actually helped me.
I learned ATI blew their 4870 launch with paper lies as well.
You're a great help friend.
