IS there going to be a ddr5 version of the 4850?

[benskia]

I'm sure I read that there were different revisions of the 4850 coming out with ddr5 memory like on the 4870.

Is this right? Any ideas when?

Thanks

What is the difference between DDR5 and 3?

 

[Klo]

First guys, its GDDR, which is actually different to DDR, second, GDDR5 it meant to have something like 2 or 4 time the bandwidth of GDDR3 ( I think).

gddr3 is actually very similar to ddr2, Klo. gddr5 has twice the throughput of gddr3 per clock.

with the 4850 at £130 and the 4870 at £200 even if they did make a gddr5 4850 it would probably cost £170 and who would buy that over the 4870?

 

[james.miller]

that would be interesting, what with the only differences being the ram and the clockspeed.

Can't see it happening as it would be an underclocked 4870 then and people would be buying them instead of the "real" 4870's.

As pastymuncher says

Would negate the need for the 4870

what was gddr4?

 

[Lightnix]

GDDR4 was just an incremental upgrade to GDDR3 that was slightly faster, consumed less power but had quite relaxed timings. I'm fairly sure the 4850 is GDDR3 and the 4870 is GDDR5 to try and keep the products at a reasonable distance from one-another.

that would be interesting, what with the only differences being the ram and the clockspeed [and the dual slot cooler]

Yes its called the HD4870!

Yup, who would buy a 4870 when you could just buy a cheper 4850 and clock it up to a 4870.
