The GT300/Fermi Thread - Part 2!

[zerazax]

Wow that IHS is smaller then that on GTX 285 die.

Holy smokes its almoust the size of the G80 ihs.

Hahahaha....snap.

Uh, what?

First of all, you can't prove die size off IHS - and besides, the IHS doesn't seem as large as GT200 but let's put it closer to inspection:

GTX 280


GTX 480


So no, they're actually pretty close in IHS. Somewhere between GT200 and GT200b is my bet - ~500mm^2

Rev A2?

According to information from board partners circles the GTX 480 could be less than 512 shaders cores exhibit.

Hmmm

They also show the IHS is about 4.2 cm across

[annihilat0r]

yeah and why were the bottoms blacked out? Maybe this card isn't PCIE but........... ISA??

I smell another Charlie article out of this

[zerazax]

I'm not photoshop expert, and this is NOT going to be an exact representation (due to the differing angles of the cards, etc. there will be skewed results) but I cooked this up for those wondering about IHS comparisons between GTX280 and GTX480 and it's worth some talkin:

[Chumbucket843]

so ~540mm2? 23.4mm*23.4mm!

That heat sink looks like its using 5 direct touch heat pipes.

Don't know if anyone noticed but nvidia has 300 series driver options on their site now.

[H2O]

Don't know if anyone noticed but nvidia has 300 series driver options on their site now.

Probably for the low-end GT315 type chips that are available to OEMs right now.

Yes the release of geforce 196.75 drivers brings support for the geforce 300 Series.

[takamishanoku]

Can anyone tell how many shader cores from the 480 pcb?

[mapel110]

Can anyone tell how many shader cores from the 480 pcb?

You can't tell that from a picture. But the Geforce 480 will have 512 Shader Cores.

[DeathReborn]

I really like the PCB layout, its nice and clean, I am starting to fear it will run really hot, only reason I could see to add the cut out in the PCB is if the cooler was unable to work well without it.



Its really about time Nvidia did that, will also save them some money I bet.

I am starting to think I will really get to see Fermi in person at PAX later this month, It will be nice to have a two player field again in PC graphics.

Ironically if they had kept the NV I/O chip it would have been much easier to change it for a newer version allowing 3+ display outputs without having to redesign the GPU. In a way it had its benefits.

I don't think this is certain, like I said before someone who has been giving me reliable info (I don't call it a 'source' anymore, it makes me look like I'm trying to look like a journalist or a spy ) , after insisting that it would be 512sp for weeks, said that it was recently decided that the top part would be 480SP at launch.

And if you look carefully, some other people have been pointing to 480SP recently.

Gigabyte GTX 480 and GTX 470 retail boxes

[annihilat0r]

Awesome!

[InCredible]

so both are 384bit

[Chumbucket843]

hmmm... the gtx 470 has 1536MB VRAM. maybe it has a 192 bit bus with 24 rop's, 32 tmu's and 256sp's with g92 clocks?

or maybe that was a typo. one side says 1280MB and one side says 1536MB.

lol, WTF indeed ?

a huge typo in the front of the box is unlikely, so its def 320bit and 1280mb.

[hennyo]

so both are 384bit

yeah, now that I notice, is the 470 just a complete softmod on other features from the 480?

Another picture - 1280MB

[ethomaz]

This pictures are fakes??? Because in this picture has written "GIGABYTE ATI 5000 Series models now support DirectX 11".

[annihilat0r]

Hahaha OMG... yeah, these must be fake

[Mabyboi]

this pictures are fakes??? Because in this picture has written "gigabyte ati 5000 series models now support directx 11".

oh man! I just saw that!
