Hynix Rolls-out 7 GT/s GDDR5 Memory Chip

DRAM major, Hynix has announced the depelopment of 7 GT/s GDDR5 memory chips for use by the visual-computing industry. These chips are built on the company's 54nm silicon fabrication technology.

The 1 Gb (128 MB) chips labelled H5GQ1H24AFR operate at the fastest speeds so far: 7 Gbps (or GT/s), which is a 40% boost in speeds compared to the older 5 GT/s chips already in production. The chip handles up to 28 GB of data per second across a 32-bit wide interface. The incorporation of new fab. processes also means reduced power consumption at 1.35V power supply. The JEDEC-standard 1Gb GDDR5 graphics DRAM chip targets high-end applications such as game consoles and graphics cards. The company will commence volume production in the first half of 2009.

28GB/s at 1.35v. sounds like we know whats going on the next gen video cards.

w00t ,did they mean it is really shown 28gb/s in gpu-z

It means, at reference speeds, 28 x [number of chips] = bandwidth shown in GPU-Z.

More like 8*28=224GBps combined memory bandwidth of 8 chips.

Yup, although in some cases, AIBs piggyback memory chips (two chips are made to share a 32-bit wide channel), so the chip count becomes abstract. If card has 8 chips, (256/32 = 8), then yes, 224 GB/s.

No, Hynix said sometime in H1'09. That's too late for RV790-based SKUs.

How about for the RV8xx-based SKUs: too late for those too?

Depelopment? shouldnt it be Development ;).

Yeah the new 5X series could have these which would be a boon.

next gen ATI . . . unless nVidia is finally willing to stick their foot in their mouth over the whooping the HD4000 series gave them.


I'm sure ATI will be the first to jump on this, though . . . the red-camp has a hard-on for brand-new industry tech. Just go ahead and mention PCI-E 3.0 and you'll hear a red-camp engineer shout "dibbs!!!!"

So...any chance that ATI might make a new chip?

Don't know. RV870's launch is largely dependent on when it's able to tape it out for TSMC. It could be as early as March, or as late as July. Normally we would expect a small gap between the commencement of mass-production of these DRAM chips and those graphics cards. Since we don't know exactly when either of them start mass production, we can't even take a guess. As for RV790, some say it's already taped out and is awaiting mass production, some say it's pushed to very late 2008. In either case it's too late for these chips to make it to RV790 SKUs.
