ATi's next notebook GPU 90nm?

[Karma Police]

Specifically, what are the chances that it is 90nm versus 110nm?
If it's 110nm, it'll just be a X800XL in a notebook.

But do you think ATi is daring enough to release the R520 & the M28Pro at E3 at the same time? Just to demontrate their 90nm prowess?

Errr, haven't you missed one out?

M28 Pro is just a 16-pipe version of current R4X0 technology (Mobility X800), which personally I didn't think would ever be released. It won't be fabbed on 0.09u - either 0.13u low-k or 0.11u.

R5xx will be in 90nm. So there will be mobile versions too.
My personal opinion is that since M6 there were no real mobile Chips @ATI or NV. They consume too much power for real mobile notebooks (subtable!!). EDRAM and very low power consumption (no cooling needed) ...that was mobile. I'm wondering why there is no real mobile version of DeltaChrome used. The ULV variant consumes very very less power.

M6 did not have any EDRAM.
Almost all ATI's mobile chips in recent years have had memory on same package, different die than the gfx core.
for example my M10 has 4 32x4Mbit chips, making it 64MB, 128 bits.

so my M10 consumed too much power when I could play a 3d game "only" 2.5 hours on battery power?

As a basic rule: So far, there's no commericial EDRAM based PC-graphics chips and this means desktop as well as mobile. At least two have reached silicon phase from two different companies, but neither one went full production.

1.)ATI stated, there is EDRAM. (8MiB look at the Thinkpad X24!)
2.)The battery time depends on the capacity too. On subtablenotebooks there is no space and weight available for high capacity. So you have to reduce the consumtion dramatically. Every watt means a few minutes of lifetime. M10 inkl the BGA consumes still to much for that. (I don't speak about the huge >2kg Notebooks)

look, eDRAM needs totally different core design. You can't just slap it in.
Also, be sure that you don't mix up here eDRAM and ram in same chip package. (which ATI has been using for a while now.)


one more thing, is there working eDRAM fabs running at 0.13µm? afaik, NEC was testing this, but I haven't followed the development during last 6 months.

EDIT: can you give my a link reference where is stated that M6 has eDRAM? until I am proven wrong, I'll continue saying that there's no commericial desktop nor notebook graphics chip that uses eDRAM.

There is. Or rather, there was. The Neomagic MagicMedia chips.

interesting... need to look up specs for those.

1.)ATI stated, there is EDRAM. (8MiB look at the Thinkpad X24!)

google X24 edram founds 0 pages which talk about thinkpad.
google X24 gives some pages about X24 which say it has ATi gfx chip.
So point me to the place where you heard about X24 having edram.

ATI has only talked(and not only talked) about using EDRAM only with the flipper/gamecube.
And that chip was designed by artx befire the ati/artx fusion.

the memory on the M6 is ON PACKAGE, but not ON DIE.
Do you understand the difference between package and die?

2.)The battery time depends on the capacity too. On subtablenotebooks there is no space and weight available for high capacity. So you have to reduce the consumtion dramatically.

.. but what has this to do with the differnece between M6 and M10?

That was just, what I heard, so calm down.

eDRAM = embedded dynamic RAM. It's embedded directily into the core. First one with eDRAM was IIRC the Neomagic Chip.

.. but what has this to do with the differnece between M6 and M10?

The power consumption. Batterytime != Powerconsumption. If M10 would need less power like M6 the batterytime would increase.
So what's is the problem?
