ATI and NVIDIA both onboard for Samsung 80nm GDDR4

Samsung Semiconductor Incorporated has just announced that the company has started mass producing its GDDR4 memory for graphics cards.  GDDR4 is now JEDEC sanctioned and commercially “ready” for video card manufacturers.  GDDR4 is the memory successor to GDDR3 -- both of which are unrelated to the JEDEC DDR3 memory standard.

The new GDDR4 memory has a data transfer rate around 2.4Gbps on a 32-bit bus.  Samsung is shipping the new 80nm memory in 512Mb configurations, which is likely configured in 16x32 layouts.  Samsung also claims that this 2.4Gbps GDDR4 showed a 45% power savings when compared to 2.0Gbps GDD3.  The reduction in power is clearly a welcomed trend.

"We're delighted that we'll be able to use GDDR4 from Samsung in our latest graphics cards,"."Samsung's timely introduction will increase the performance of our upcoming products and ultimately improve the gaming experience for our users,” claimed Joe Macri, ATI Senior Director of Engineering.

ATI is expected to launch its R580+ graphics card before the end of the year.  This card is essentially the R580 (Radeon X1900) ASIC with GDDR4 memory – which was built into the R520 and R580 design from the start.  NVIDIA has GDDR4 on its roadmap for the next generation GPUs scheduled for sampling this fall as well.

Samsung isn’t the only player in the GDDR4 market: Hynix just announced the company would completely refocus its DRAM efforts specifically on graphics memory.  More importantly, Hynix has already announced its GDDR4 is running at 2.9Gbps – a feat Samsung would have to best if it is to stay the number one DRAM supplier.

Very true...
Though I deviated from this when I went from my 9700 Pro (the best video card purchase I have EVER made... what a fantastic card) to a 6600 GT (switch to a PCIe platform)

Though I did eventually at the second 6600 for some SLI performance, it still gets SMOKED compared to a SINGLE 7800. Even a 6800 at the time of purchase could equal a pair of 6600s.

Next time around I will be getting the top end once again... hoping to have as much success as I did with my 9700 Pro.

Good grief...

That was that long ago! What a great card...
(I was one of the "few" Anand talked about in being able to purchase the card when it came out... but got a heck of a deal on it)

What relle matters is the time u buy that top end or whatever part... Never go with the newest 1, coz ur money will be burnt real fast... i like to wait a few months.... coz 10 fps more a month ahead, will not make my life any better... while maybe a hundred bucks saved, might...

p.s. That goes to the middle class :P
