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.

We do have Cyberlink's software, but as it uses different code paths, the results are near-useless for a hardware review. Any differences could be the result of hardware differences, or it could be that one of the code paths is better optimized. We would never be able to tell.Our focus will always be on benchmarking the same software on all hardware products. This is why we bent over backwards to get something that can use DirectCompute, as it's a standard API that removes code paths/optimizations from the equation (in this case we didn't do much better since it was a NVIDIA tech demo, but it's still an improvement).

I have one of these and I know it outperforms the GTX 280 but not sure what it'd be like against one of these puppies.dagamer34 - Wednesday, September 23, 2009 - link
I need my bitstream Dolby Digital TrueHD/DTS HD Master Audio bistreaming codecs!!! :)ew915 - Wednesday, September 23, 2009 - link
I don't see this beating the GT300 as for so it should beat the GTX295 by a great margin.tamalero - Wednesday, September 23, 2009 - link
dood, you forgot the 295 is a DUAL CHIP?SiliconDoc - Wednesday, September 23, 2009 - link
roflmao - Gee no more screaming the 4850x2 and the 4870x2 are best without pointing out the two gpu's needed to get there.--
Nonetheless, this 5870 is EPIC FAIL, no matter what - as we see the disappointing numbers - we all see them, and it's not good.

Problem is, Nvidia has the MIMD multiple instructions breakthrough technology never used before that according to reports is an AWESOME advantage, lus they are moving to DDR5 with a 512 bit bus !

So what is in the works is an absolute WHOMPING coming down on ati that BIG GREEN NVIDIA is going to deliver, and the poor numbers here from what was hoped for and hyped over (although even PREDICTED by the red fan Derek himself in one portion of one sorrowful and despressed sentence on this site) are just one step closer to that nail in the coffin...

Yes I sure hope ati has something major up it's sleeve, like 512 bit mem bus increased card coming, the 5870Xmem ...
I find the speculation that ATI "mispredicted" the bandwidth needs to be utter non-sense. They are 2-3 billion in the hole from the last few years with "all these great cards" they still lose $ on every single sale, so they either cannot go higher bit width, or they don't want to, or they are hiding it for the next "strike at NVidia" release.

So you're comparing this product with a not yet release product and saying that the not yet released product is going to trounce it, without any facts to back it up? Do you have the hardware? If not, then you're simply ranting.Will the GT300 beat out the 5870? I dunno, probably. If it didn't, that would imply that the move from GT200 to GT300 was a major disappointment for NVidia.
I think that EPIC FAIL is completely ludicrous. I can see "epic fail" applied to the Geforce FX series when it came out. I can also see "epic fail" for the Radeon MAXX back in the day. But I don't see the 5870 as "epic fail". If you look at the card relative to the 4870 (the card it replaces), it's quite good - solid 30% increase. That's what I would expect from a generation improvement (that's what the gt200's did over the 9800's, and what the 8800 did over the 7900, etc).
BTW, I'm seeing the 5870 as pretty good - it beats out all single card NVidia by a reasonable and measureable amount. Sounds like ATI has done well. Or are you considering anything less than 2x the performance of the NVidia cards "epic fail"? In that case, you may be disappointed with the GT300, as well. In fact, I'll say that the GT300 is a total fail right now. I mean jeez! It scores ZERO FPS in every benchmark! That's super-epic fail. And I have the numbers to back that statement up.
Since you are making claims about the epic fail nature of the 5870 based on yet to be released hardware, I can certainly play the same game, and epic fail anything you say based on those speculative musings.

Well the GT200 was 60.96% increase average. AT says so.http://www.anandtech.com/video/showdoc.aspx?i=3334...">http://www.anandtech.com/video/showdoc.aspx?i=3334...
So, I guess ati lost this round terribly, as NVidia's last just beat them by more than double your 30%.
Great, EPIC FAIL is correct, I was right, and well...

Team Green foames out of their mouthes. It's funny to watch.SiliconDoc - Wednesday, September 23, 2009 - link
Glad you are having fun.Just let me know when you disagree, and why. I'm certain your fun will be "gone then", since reality will finally take hold, and instead of you seeing foam, I'll be seeing drool.
