News - Leaked slide sheds light on AMD Radeon HD 6970 and 6950

[HEXUS]

High-end successors to 5870 and 5850 to land in late November?

Read more.

Slide is a fail.. AMD would not be stupid enough to get the units wrong on memory speed. 6Gbps is several orders of magnitude out.

[cameronlite]

I thought the 6970 was the new 5970? Wasnt the 5970 sort of a 5870x2?

Surely 1GB of memory is a bit low for a dual card?

[nibbler]

it's set to be a single GPU card supposedly.
I really have no faith at all in these slides, why would AMD spend the whole time having meetings with dubiously trustworthy workers instead of doing any actual work?

From reading other discussions on here I think the consensus is that the 6970 is going to be more of a replacement for the 5870 - so yeah that would make it single-GPU. 6000-series naming is going to confuse a few people I think!

[cameronlite]

ah yes, i did read about the 5870 becoming the 6970 - noob comment, sorry

so does that mean the 6970 x2 will be the 6990?

Welcome to the real world.

[ultrasbm]

Welcome to the real world.

Precisely.

Don't want to do any work? Simply call a meeting...!

6Gbps is the speed of the 5450 ram (800mhz ddr2/3 64bit) , s , yeah , ummmmm

heres another of the slides:

so whats a GTX450 again

calliing fake

and if you look the badwidth is mentioned as Gpbs - thats Giga Bits Per Second , ......

I have been wondering that myself, i suspect they might bring the x2 suffix back as it makes it clear you have 2 GPUs on the single board.

erm... current memory speed on a 5870 is 4.8Gbps (x 256/8 bytes = whatever the ridiculous bandwidth is actually available!).

I believe they started using Gbps instead of MHz with the 5 series due to the differences between clock speed, transfers and bitrate for GDDR5 memory. Basically it'll be GDDR5 clocked at 1500MHz. Nothing wrong with the slide there...

Given that both of these slides come from an August OEM briefing, prior to either the dropping of the ATI brand or the release of the GTS450; and given that they contain very little in the way hard facts (remember the < 300W TDP on the GTX480 that turned out to be 250W? And quelle surprise! that AMD are targeting the new card ranges to perform just above the nvidia equivalents!) I hardly think they'd be worth faking. In fact, in news terms this whole thing is a bit of a non-event.

The only question is whether the Juniper core will get a touch up or whether they'll just directly rename the 5750 / 5770 to 6750 / 6770.

You sure? So you can reach the speed of ultra fast DDR5 VRAM with a few SSDs in RAID?

SATA 2 is 3Gbps.

I thought the 5870 mem speed was 153.6GBps, so about 1500Gbps.

edıt: or I could actually read.. sorry. okay, makes sense consıderıng the x256 /bytes thing. Speed, not bandwidth. So hard to compare until we know the bus width.

No worries, does my head in most days (I'm just particularly lucid this week apparently ). Bus width is 256bit apparently, so these cards are going to be heavy on bandwidth and pixel fill rate, but a little light on shading power. Should make for interesting benchmarks when we get some official ones

300 Watts for a single chip card, have AMD hired some of Nvidia's staff??
