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

Dawn of War II
Dawn of War II is our other RTS benchmark. It’s among the more challenging games in our collection, leading to there being a definite cutoff for playability.
Here we are going to see the 5870’s other dominating performance of the day, as it crushes the 4870X2 and beats out the GTX 295. This game responds very poorly to CF/SLI, which means it’s really only a contest among single-GPU cards and the fastest multi-GPU cards. AMD’s cards in particular can’t get any traction, as Crossfire offers a minimal gain at best, and a performance loss at worse. This will be the only game where 5870 CF loses.

I'll be watching you for the very same conclusion when NVidia launches soft and paper.I'll bet ten thousand bucks you don't say it.
I'll bet a duplicate amount you're a red rager fan, otherwise YOU'D BE HONEST, NOT HOSTILE !

It may be paper-launch in the US, but here somewhere in South East Asia I can already grab a Powercolor 5870 1GB if I so desire. Powercolor is quite aggresive here promoting their ATI 5xxx wares just like Sapphire does when the 4xxx series comes out.SiliconDoc - Thursday, September 24, 2009 - link
I believe you. I've also seen various flavors of cards not available here in the USA, banned by the import export deals and global market and manufacturer and vendor controls and the powers that be, and it doesn't surprise me when it goes the other way.Congratulations on actually having a non fake launch.

"The engine allows for complete hardware offload of all H.264, MPEG-2 and VC1 decoding".This has afaik never been true for any previous card of ATi, and I doubt it has been tested to be true this time as well.
I have detailed this problem several times before in the comment section and never got a reply, so I'll summarize: ATi's UVD only decodes level 4 AVC (i.e. bluray) streams, if you have a stream with >4 reference frames, you're out of luck. NVIDIA does not have this limitation.

Yeah and my GTX 280 has to run full throttle (3D frequency) just to play a 720p content and temp climbs the same as if it were a 3D game. Yeah it can decode some *underground* clips from Japan, big deal. Oh and it does that for only H.264. No VC-1 love there. I am sure you'd think that is not a big deal, but the same applies to those funky clips with 13+ reference frames. Not a big deal. Especially when AMD can decode all 3 major codecs effortlessly (performance 2D frequency instead of 3D frequency)rennya - Thursday, September 24, 2009 - link
G98 GPUs (like 8400GS discrete or 9400 chipset) or GT220/G210 can also do MPEG2/VC-1/AVC video decoding.The GPU doesn't have to run full throttle either, as long as you stick to the 18x.xx drivers.

Ryan,Great article, but there is an inconsistancy. You say that thanks to there only being 2 TDMS controllers, you can't use both DVI connectors at the same time as the HDMI output for three displays, but then go onto say later that you can use the DVI(x2), DP and HDMI in any combination to drive 3 displays. Which is correct?
Also, can you play HDCP protected content (a Blu-Ray disc for example) over a panel connected to a Display Port connector?
Otherwise, thanks for the review!
Ryan Smith - Wednesday, September 23, 2009 - link
It's the former that is correct: you can only drive two TDMS devices. The article has been corrected.And DP supports HDCP, so yes, protected content will play over DP.

Thanks for clarifying that Ryan - It confirms what I thought.. :-)chowmanga - Wednesday, September 23, 2009 - link
I'd like to see a benchmark using an amd cpu. I think it was the Athlon II 620 article that pointed out how Nvidia hardware ran better on AMD cpus and AMD/ATI cards ran better on Intel cpus. It would be interesting to see if the 5870 stacks up against Nv's current gen with other setups.
