Sapphire Radeon HD 5870 and HD 5850 Smile for the Camera
Here are the fist pictures of Sapphire's Radeon HD 5800 series offerings: Radeon HD 5870 1GB and Radeon HD 5850. The cards sport the usual sticker design of a CGI girl in a reddish background. With these cards having the cosmetic "red-streak" cleaving the cooler shroud in the center, the so is the sticker. This is also perhaps the first public picture of the Radeon HD 5850, and our size projections were right: While the Radeon HD 5870 maintains a long PCB, the HD 5850 is about as long as a Radeon HD 4870 (reference design). Both accelerators stick to the reference AMD design.

Well, ati have been doing it for quite some time.
4850 is crippled to some degree, however all shaders live.
4830 is crippled, shaders removed.
4860 is crippled, shaders removed. less crippled than 4830. or crippled 4890's.
Ati rushed to get 4xxx out while 5xxx is been a longer process, might have picked up more crippled cores due to longer production run than 4xxx had in the start.
might not get a clear answer on that from ati :P
I think you're really looking too far into this. I don't think it's foundry problems -- I think it's more just to do with ATI finally increasing a bit of revenue and market share, and finally having the time and money to do those same practices that other video cards producers perform, having long enjoyed their time at the top.
And even if it's harvesting "defective" cores, that's purely academic, not the consumer's concern at all. The consumer gets a warranty-backed product.
I think there's a "preponderance of evidence." :laugh:
I don't understand the fecking CGI girl though... whats the point? Crap logo.
Whats the release date of the 5850? i forget..
Low memory bandwidth, limited to 1680x1050.
As a reminder, 256 bit GDDR3 on high end cards do 73 gb/sec
256 bit midrange GDDR5 does 140 gb/sec.
Going to 512 bit GDDR3 would make it more expensive than 5870 and still output less performance.
And the cores being defective doesn't matter, as I've said, it is standard practice. Maybe if we don't feed him, he'll go back under his bridge...
The Saphire Vapor-X coolers for the 4870 and 4890, now THAT is design!
The 4830's core is both crippled and clocked lower but still manager keep up with the 4850.
www.techpowerup.com/reviews/Powercolor/HD_4830/26.html
The 4850 is less than 10% faster due to its suckass bandwidth.
Not to mention the 4770 which can take on a 4850 simply becaue it is clocked higher. (And its memory clocks much better)
The number of tmus and shaders don't seems to matter as much as the number of ROPs,
this might be due to the fact that most games are still optimized for shader model 3.0.
Now where are the benchmarks!!!! :cry:
since it has basically twice the power of a 4870 but the bandwidth does not seems to grow nearly as much. :ohwell:
