Quad Crossfire coming soon from ASUS and Gigabyte

[infrared]

yep, having 8x pci-e on each gpu is kinda stupid in my opinion. But to be honest, I think it's a great peice of engineering and i don't see any other way to make it 16x for each core.

Anyway, awsome peice of kit!

Quake2owns > you can stop right now.

All others, keep your comments to yourselves. It makes you look just as bad when you come back at them. Tell a mod/admin and they will take care of it.

And I'm sick of people telling others to "STFU" too. Next person I see tell some one else to "STFU" will have a nice vacation.

I should close this thread now... but I wont. Next comment that is at all out of line from any of you, thread will be closed and you'll be dealt with.

And to clear this up a bit, here are some facts.

Lets start with the basics...

• Bit = 1 Binary digit
• Nibble = 4 Bits
• Byte = 8 Bits
• b = Bit
• B = Byte
• Mb = MegaBit
• MB = MegaByte
• Gb = GigaBit
• GB = GigaByte
• So on and so forth...

Prefixes:

• Kilo = 10^3
• Mega = 10^6
• Giga = 10^9
• Tera = 10^12
• Peta = 10^15
• Exa = 10^18
• Zetta = 10^21
• Yotta (Looked that one up ) = 10^24

But don't forget the "24" in the 1024... it's not a 1000 Bytes in a KiloByte, it's 1024 Bytes. (this is why a 200GB hard drive shows up as 186GB due to the "24" being dropped)

Now PCI-E comes in 1x, 2x, 4x, 8x, 16x, and 32x. These number are the amount of lanes, not times faster than AGP and what not.

• PCI-E 16x = 16 lanes.
• 1 lane = 2.5Gb/s (GigaBits) or ~250MB/s
• 16 lanes (16x) = 40Gb/s (GigaBits)
• 40Gb/s = ~4000MB/s
• PCI-E is full duplex so it has two directions, and you double the bandwidth. A lane is up/down stream.
• PCI-E 16x = ~8000MB/s (upstream, downstream)
• 8000MB/s = ~8GB/s

Calculations above are rounded to save time and to just give a general idea.

Thanks to DantheBanjoman as well for checking this over and picking out my typos.

well thank you djbbenn. me and this guy have butted heads on technical specs and countless other issues. please keep an eye on him cuz we (as in casual board readers) dont need this kind of attitude.

as far as i know theoretically the agp8x bandwidth limit has not been reached. agp4x definatly has but not 8x. these cards should yeild some insane performance numbers but its not really worth the cost. either way this is a beautiful peice of tech.

The AGP 8× limit is far from reached, however PCI-e is full duplex so a videocard (or any other card) could read and write at the same time. Obviously this is an improvement.

As for quad SLI/crossfire, those techs are quite pointless to begin with for the average user. Unless you can afford 2 high end cards it's not for you. A single high end card would be much better than 2 low/mid end cards so these aren't an option either.

Good for it... I'm so glad you feel that way.

LOL, i don't think anyone was doubting that. Everyone just jumped at each others throats. Was quite scary!

it was like a brawl i made popcorn and sat at my desk and kept hitting refresh........

and as cool as these cards are im seriously thinking of switching over to nvidia for a gen or 2 as agp is the only thing im going to be having for a while (and it was givin to me by a freind of mine who whanted to save me from pci sooo) so im seriously considering a 6800gs so i can mod it and it beats my 9800pro.

Nice 3dmark06 score there Solaris My card wouldnt do any better either
