from DailyTech - Don't Get Too Accustomed to GDDR4: Qimonda Ships GDDR5 SGRAM

Global memory supplier Qimonda today announced that it is has shipped the industry’s first 512MB Graphics Double Data Rate (GDDR5) samples to partners and customers. GDDR5 SGRAM is the successor to GDDR4 SDRAM, which has yet to completely overtake GDDR3 SDRAM.

GDDR5 features data rates at 20GByte/s per component. This is double the bandwidth of the fastest GDDR3 memory.

GDDR5 operates using two different clock types. One clock type that GDDR5 comes with is a differential clock (CK), where address and command inputs are referenced. The other clock type that GDDR5 uses is the forwarded differential write clock (WCK), which operates at twice the frequency of the CK. Read and write data are referenced to the WCK.

Each write clock of GDDR5 SGRAM is assigned to two bytes.

High end graphics cores in development today, NVIDIA's next-generation architecture and AMD's R700, would be the first graphics cores capable of utilizing the new signalling required for GDDR5.



Click the link above for more. I wonder how this will affect the recent release of GDDR4, and how overclockable it will be. Apparently the memory has 2 different clocks... that should shake OCing up a bit. Other things mentioned are power saving features, particular memory I/O throttling.

Im actually working on GDDR6 right here in my room so y'kno watch for that

[aetherh4cker]

My GQDR6 will show that up.

Graphics Quad Data Rate.

Runs in a PCI Express x32 slot on a HATX motherboard.

lol you guys are funny..

I'm still waiting for quantum computers.


But is brand new graphics memory similar to brand new system memory in regards to costing a lot and giving little benefit or does Nvidia and ATI typically design the cards around it to get the advantages?

plz, my starship uses DDR900, you guys are so behind.

um... faster memory, faster video card, thats the advantage?

[Wildside]

how differ is GDDR5 from GDDR4? I mean, we r barely seeing GDDR4 GPUs n GDDR5 is right around the corner? Wow.

Lol guys, what are you talking about, you're obviously not keeping up with today's technology, you should come one day and take a look at my sixteen Nvidia G3950GTX8 Octo-GPU cards running in Octo-SLI with a combined video memory of 1TB of XGODR9, it's running ok on my PCP&C 3000kW PSU with 1300 32-MegaVolt rails. My computer's idle at about 1500 degrees celsius, 5200 on load.... still can't play Crysis on very high settings though, only get like 5 fps... sigh.

What I mean is if you look at ddr3 it offers little advantage at this time. I'm wondering if the same has been true for gddr memory.
