HD5870 = Single GPU

HD5870X2 = Dual GPU

HD5870X4 = Quad GPU

The story of a dual-die GPU from AMD/ATI has been circulating since way before the launch of R700, Radeon HD 4870X2. While it did allow many to dream, it turned out to be just a rumor, or maybe it was just to soon? Either way a source has hinted that the new card R870 will be two GPU dies glued together sharing a memory bus. This is pretty much the exact same that was said before the R700 launch, and while we can't confirm this, similar information has been posted over at Chiphell.

Both are basically saying that AMD has glued two RV870 GPUs together to build world's first dual-die GPU, which is kind of amusing considering AMD's bashing of Intel's dual-die solutions. Anyhow, this means that AMD would then be able to build what many would come to call quad-fire on a stick. Four GPU dies on the same card, R800. It also means that for the first time we will have a middle between the RVx70 and Rx00.

Specification wise this would land us on something like 1000-1200 shaders and 50-60 TMUs with RV870, 2000-2400 shaders and 100-120 TMUs with R870, and 4000-4800 shaders and 200-240 TMUs with R800. In theory (IN THEORY!), AMD could launch them as Radeon HD 5870, Radeon HD 5870 X2 and Radeon HD 5870 X4.

There isn't a salt mine big enough take with this, but we just wanted to notify you that the rumor has resurfaced. Beware.

É muito power!!! x4... já as x2 custam uma pequena fortuna imganino as x4. Devem de ter um poder nos jogos...

"Actually, it doesn't sound optimistic enough to me. If the die size of 205mm² is true, ATI could sell these things for really cheap. The Radeon HD 4830, with its 256mm² die size and 256-bit memory interface, is already selling for less than $130 USD. I'm thinking something more like this:

Radeon HD 5870 X4 (Dual MCM, 800MHz Core, 2GB 1200MHz GDDR5) - $649
Radeon HD 5870 X2 (MCM, 800MHz Core, 1GB 1200MHz GDDR5) - $349
Radeon HD 5870 (800MHz Core, 512MB 1200MHz GDDR5) - $199
Radeon HD 5850 (600-650MHz Core, 512MB 1100MHz GDDR3) - $129"

"Today appeared new information about the RV870 chip . Associate reports that this 40 nm chip models will appear at the end of present year, and to the end of first quarter 2009 it will reach the series production .

The quantity of stream processors on RV870 chip can grow up to 1000 pieces. Their resulting computational performance can reach 1,5 teraflops.

The memory capacity on RV870 video card can reach 150-160 Gbit/s. If we considers that Radeon HD 4870 with 256- bit bus and 3600 MHz DDR memory frequency ensures a capacity at the level of 115,2 Gbit/s, RV870 can raise the memory frequency to 4800 MHz DDR with constant memory bus. Qimonda company already released GDDR5 microcircuits working at frequencies up to 5000 MHz DDR .

The RV870 core area will decrease from 256 sq. mm, in RV770, to 205 sq. mm. This will allow to create the two-chip graphical solutions easily."

memorias a dar 5Ghz é que tá a dar
O preço até nem é nada por ai alem, as x4 custam tanto como as x2 que são lançadas.
