Hynix Semiconductor Introduces 7GHz GDDR5 Memory.
http://www.xbitlabs.com/news/memory/display/20081124071421_Hynix_Semiconductor_Introduces_7GHz _GDDR5_Memory.html

Hynix Semiconductor, one of the leading suppliers of dynamic random access memory (DRAM), on Monday formally announced its new GDDR5 chips capable of working at 7GHz. The company will only start shipping those chips next year.

The newly introduced 1Gb GDDR5 capable of operating at 7GHz, or 40% faster compared to chips available now, is built on the company’s 54nm process process technology. In addition to its improved speed, it is also designed to minimize power consumption at 1.35V power supply. Previous-gen GDDR5 DRAMs required 1.5V power supply and could function at up to 4.5GHz.

Hynix’s 1Gb GDDR5 graphics DRAM meets JEDEC standard and the company plans to start volume production in the first half of next year.

Hynix did not reveal whether the new 1Gb GDDR5 chips at 7GHz are already being tested by their main customers – ATI, graphics product group of Advanced Micro Devices, and Nvidia Corp. Theoretically, the new 7GHz memory chips may be used on next-generation GeForce or Radeon graphics cards; but keeping in mind that developers of graphics processors tend to be conservative regarding clock-speeds of DRAMs, the new graphics boards may feature Hynix’s latest chips at lower frequencies.

7GHz GDDR5 chips could provide 224GB/s or 448GB/s peak bandwidth when connected to a processor using 256-bit or 512-bit memory bus, respectively.

The need for bandwidth :drooling:

Just what you need for your BR2 Mod ;)

Ha ha ha, exactly :D

in all seriousness, that is some impressive bandwidth numbers.

Waiting for over 9000 before I buy.

HOLY CRAP... i dont think we'll have to worry about ram limiting our overclocks anymore...

AMD & NVIDIA Going to Select TSMC 40nm And Hynix GDDR5
http://en.expreview.com/2008/11/27/amd-nvidia-going-to-select-tsmc-40nm-and-hynix-gddr5.html

After Taiwan Semiconductor Manufacturing Co. (TSMC) announces to build 40nm process chip, Taiwan Economic News reports that AMD and NVIDIA’s first 40nm products will debut in Q1 next year. So let’s guess who can enjoy the ahead chance.

What’s funny is, as two biggest graphics tycoons in the world, AMD and NVIDIA both choose the fastest Hynix 7Gbps GDDR5 graphics DRAM for their new-line products. It’s very likely that we find Hynix’s new DRAM in AMD RV870 or NVIDIA GT216/206.

It’s rumored that the power consumption of NVIDIA GT212 i.e. 40nm GT200 is 25% less than previous 65nm chip.

As for GDDR5 graphics DRAM, ATI has taken the lead in using Qimonda GDDR5 Graphics DRAM for its Radeon HD 4800 Series.

Not sure if with such big bandwidth improvement there is going to be need for more expensive 512-bit memory bus. Anyway it looks like 2009 is going to be another great year for graphic card competition. Hopefully the 40nm process and the competition will keep the prices down.

walterman, thanks for the links.

I know a game that would fly with that bandwidth :D

Wow - it almost seems like ram bandwidth is outpacing GPU development in terms of its needs, never expected to see that so soon.

Of course there is, just increase the amount of ROPs to 64 and we need all the bandwidth available. ;)
