Samsung claims to have broken speed records with its new graphics memory

Samsung Electronics announced over the weekend that it has increased the data transfer speed on its extremely fast GDDR4 (Graphics Double Data Rate, version 4) graphics memory. The South Korean electronics giant claims that it has increased speeds by two-thirds.

Using 80-nanometer production technology, the 4Gb/s (2.0GHz) is 66 percent faster than today’s fastest commercially available memory – the 2.4Gb/s GDDR4. The new 4Gb/s graphics memory, offered in 512Mb density, has a 32-bit data bus configuration. GDDR4 uses JEDEC-approved standards for signal noise reduction to help attain the highest possible speed.

“Our new GDDR4 memory will add even more zip in video applications, making gaming, computer-aided design and video editing faster than ever before,” said Mueez Deen, marketing director, graphics memory, Samsung Semiconductor, Inc. “This will enable ultra-smooth movements in animation and make games incredibly realistic, resulting in a truly immersive user experience,” he added.

Samsung cites analyst expectations for GDDR4 to significantly boost demand for high-performance graphics memory over the next 12-18 months. The company said that it will begin customer sampling of its new chips this month.

Most video cards on the market today from NVIDIA and ATI are still using GDDR3, including solutions inside the Xbox 360 and PlayStation 3. GDDR4 memory thus far has seen limited use in recent high-end cards from ATI, and is expected to be paired with the upcoming R600 GPU.

I knew there was logic in ATI/AMD waiting to start printing R600-based cards. I just hope this decreases bottom line PSU requirements.

I really doubt it will help much since I don't think the memory is whats sucking up all the power on current GPUs. Its the several hundred million transistors on the GPU itself. Granted 512MB-1GB of graphics memory is a ton of transistors as well.

No matter how many billion transistors could be on the memory side of the things, the heat is produced on the chips that need the most cooling - that would be the graphics core itself.
On many cards that need active cooling for the graphics chip, memory chips don't even have passive heat sinks.

There is also the rumor that AMD is waiting to have the entire R600 lineup on 65nm. If they waited to have it all on 65nm and this memory, I can understanding pushing it back to May. But, please, no more delays after this.

That's ridiculous. If AMD could have gotten their cards out sooner, they would have. The simple, obvious truth is that the silicon wasn't ready.

Maybe you think NVidia has a top secret strategy reason for delays in their Windows Vista/DX10 drivers?

Further, it's not hard to stick faster DDR4 memory on an existing DDR4-based card. They could call it the "X2900XTX XXX OC Edition" or something, and let their AIB partners release it as a special version.

There won't be a decrease in GPU requirements, because both kinds of DDR4 operate at the same voltages. Increasing the DDR's speed by 20% increases the power use by 20%.

Increasing the DDR's speed by 20% increases the power use by 20%.

Actually, as we saw with Prescott, power usage tends to go up geometrically with a linear progression in clock speed... so it's probably more than 20% more power for 20% more clock speed... But that just makes your point all the more relevant.
