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

Conclusion
The easiest kind of product for us to write about is the kind that’s clearly superior to its competition. The hardest kind to write about is the kind that’s stuck in the middle. For the 5870, we have the latter case.
Let’s be clear here: the 5870 is the single fastest single-GPU card we have tested, by a wide margin. Looking at its performance in today’s games, as a $379 card it makes the GTX 285 at its current prices ($300+) completely irrelevant. The price difference isn’t enough to make up for the performance difference, and NVIDIA also has to contend with the 5850, which should perform near the GTX 285 but at a price of $259. As is often the case with a new generation of cards, we’re going to see a shakeup here in the market as NVIDIA in particular needs to adjust to these new cards.
The catch however is that what we don’t have is a level of clear domination when it comes to single-card solutions. AMD was shooting to beat the GTX 295 with the 5870, but in our benchmarks that’s not happening. The 295 and the 5870 are close, perhaps close enough that NVIDIA will need to reconsider their position, but it’s not enough to outright dethrone the GTX 295. NVIDIA still has the faster single-card solution, although the $100 price premium is well in excess of the <10% performance premium.
Meanwhile AMD is retiring the 4870X2, which ended up beating the 5870 enough that we would consider it a competitor to the 5870. However, you can’t consider it if you can’t buy it.
Then we have the multi-GPU space, where things are rather clear. Having the fastest single-GPU card makes the 5870 in Crossfire the fastest dual-GPU solution by far. Unfortunately we didn’t have a chance to benchmark a GTX 295 Quad SLI setup, but given the notoriously finicky nature of Quad SLI and Quad Crossfire, we’re comfortable calling the 5870 CF the better multi-GPU solution.
And that brings us to our next conundrum: if dual-GPU setups can overshoot the 5870, does that make them better? At equal performance levels, we would take a single-GPU setup any day of the week; there are no profiles to deal with or the sometimes inconsistent scaling in performance (see: Dawn of War II). Even with a slight lead in performance, we would pick the 5870 over the 4870X2 or GTX 295 so long as the latter were not significantly cheaper. As it stands the 5870 is the greater value, even if it's not the fastest card.
Moving away from performance, we have feature differentiation. AMD has a clear advantage here with DirectX11, as the 5870 is going to be a very future-proof card. The 8800GTX is a good parallel here – it took 3 years for it to really be outclassed in terms of features, and the performance is still respectable today. DX11 is going to give the 5870 the same level of longevity when it comes to being up-to-date on features, although we’ll see if its performance lasts for quite as long. When games using DX11 arrive, it’s going to bring about a nice change in quality (particularly with tessellation). However it’s going to be a bit of a wait to get there.
On that tangent, we have Eyefinity. Unlike DX11 Eyefinity is something we can take advantage of today, but also unlike DX11 it’s not necessarily an improvement. As Anand discussed when attempting to use it, when it works it’s absolutely great, but at the moment it has some real teething issues. And it’s expensive – even 3 cheap TV-quality monitors is an investment for most people of hundreds of dollars on top of everything else. It’s very much like a certain NVIDIA feature in terms of cost, goals, and its hit-or-miss nature. Eyefinity is something we’re going to want to keep an eye on to see what AMD does with it in the future, because they’re on the right track. It’s just not something that’s going to tickle the fancy of very many people today.
Wrapping things up, for those of you who were expecting the 5870 to shake things up, the 5870 is certainly going to do that. For those of you looking for the above and a repeat of the RV770/GT200 launch where prices will go into a free fall, you’re going to come away disappointed. That task will fall upon the 5850, and we’re looking forward to reviewing it as soon as we can.
At the end of the day, with its impressive performance and next-generation feature set, the Radeon HD 5870 kicks off the DirectX 11 generation with a bang and manages to take home the single-GPU performance crown in the process. It’s without a doubt the high-end card to get.

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.
