AGP 8X or PCI Express


M

Mad_Unit

I've been a way from the computer building seen for a while and
don't fully understand PCI express. I'm wanting to upgrade my video
card and there are more PCI express cards out there than AGP. Do I need
a new board to run a pci express graphics card? If so then that cuts
$80 bucks off my graphics card upgrade. I was planning to spend around
$300. So then will a $220 pci express card beat a $300 AGP card? I know
there are tons of variations of each but just in general.

Thanks guys

Yes. And possibly a new CPU and memory, depending on what you currently
have.

No.

Well actually 'maybe', since AGP cards are now getting to be
expensive/rare/specialty items, but IMO the reason the PCIE card will
win is because it's cheaper (because the volume is supposed to be
higher, of because the manufacturers are trying to kick-start sales, or
whatever), not because PCIE is a magic solution to anything that an AGP
card was suffering from.

Each to their own, but I'd never spend $300 for a graphics card. That's
too close to the bleeding edge, and you know it'll be $150 or so for the
same thing before you've got much of anything that actually needs it.

agp wont be rare or specality for years. 90% of the market still uses agp
wont go away for at least a year or so.

1) So I exercised a slight amount of hyperbole. Just go and look at
recent graphics cards, and you'll see that PCI-E is what the market is
pushing.

2) Your newsreader is broken and fails to trim signatures properly.
There is a fix available.

Its pushing but wont be much of a push took AGP years to take over PCI and
it will take PCI express years to take over agp. Look at the 6600 and 6200
series being released to agp when they didnt really want to. Most of the
market is agp and will be for awhile. Now this time 2006 or 7 I could see
getting a PCI express mothearboard but till then AGP is still the way to go
performances between the 2 right now is negilible. (sp) so I say stick wtih
AGP for now.

That depends on which end of the market you look at - at the very top end,
there is no shortage of AGP... because there's a bunch of gamers out there
who have to upgrade at every notch. In the mid-range, say FX6600GT, AGP
was slow to get started but it is easly found now at a slight price
premium. At the low end, which implies fresh builds, AGP is pretty much
dead.

I don't know if later versions of mine have been fixed but I'm not even
going to bother to look - upgrades are often too painful.:)

Yes it's a new interconnect standard with completely different signalling.

No, for any given GPU, the performance is still much the same between AGP
and PCIe. The latest GPUs are natively PCIe and to make an AGP card,
require a bridge chip which increases the price by ~$30. Also note that
the AGP versions require auxiliary 12V power from a drive power
connector... fugly!

Using the life history of dying technology is no way to forecast the future,
son.

You're way off.

... it will take PCI express years to take over agp.

to forecast the future, ...

Besides, you have to look at all the historical
examples.
- PCI: still with us
- ISA: took many years to go
- VLB: gone in a flash
- EISA: gone even faster than VLB

My guess is that new graphics chips are already going
onto PCIe first, then (maybe) being back-ported to AGP.
Within 18 months, the backporting will cease. Within
36 months, AGP will be off the market.

You missed MCA!

They are .. like I said, the makers as busy backing PCIE big time.
then (maybe) being back-ported to AGP.
Within 18 months, the backporting will cease. Within
36 months, AGP will be off the market.

I sort of doubt that, given the after market size .. although I guess
PCI graphics cards (not PCI-e) could cover quite a bit of that. What I
=do= believe will happen (already is) is that AGP cards will be at a
considerable premium to the PCI-E versions, and with a much reduced
selection of makers, chipsets, and performance options.

MCI??

No. MCA - MicroChannel Architecture. IBM's proposed
replacement for ISA. It competed with EISA and VLB.
All three lost out to PCI.

MCA was one of IBM's several initiatives in the PS/2
timeframe that were intended to both evolve the PC
infrastructure, and recapture IP control of that
infrastructure.

That MCA is unheard of today, and the IBM-Lenova deal,
tells you how that all worked out.

But PCI is not a "video bus" like AGP is. It's a general-purpose bus,
and it be with us long after AGP fades to oblivion.

The long life of PCI cannot be used to predict a long life for AGP.
