无论多么成熟的技术,落后了还是要被取代.
PCI Express means death of AGP standard
A PANEL OF Intel specialists working on the PC Express specifications confirmed
today that when products are released it means the death of the AGPx spec, with
rev eight being the last.
While PCI Express means X16 next generation graphics delivering 4GBs per second
per direction, that may mean that when Nvidia releases its PCI Express card,
you'll have to buy a whole new PC to plug it into.
PCI Express products are due to ship in the second half of next year, with
other radical changes happening in the notebook and server segments too. The
specs are far advanced and Microsoft is very likely to take full advantage of
some of its new futures, probably with Longhorn.
Bala Cadambi, who heads up the PCI Express initiative, said that the new specif
ication will run fine with existing BIOSes and drivers, and software, but it
has "a lot of features software can take advantage of".
Those include isochronous support for streaming media for TV tuners, for graphi
cs and for cameras.
The first release of products also means an X or greater IO performance for
Gigabit Ethernet, and 1394, with 250MBs per second per direction.
The notebook PC will see the death of the old PCMCIA form factor, with new card
s, codenamed oddly enough Newcards, taking their place. Two Newcards will fit
in the space of one Cardbus card, and they'll be able to use PCI Express or USB
2.0.
The advantages of the new form factor will include low wattage, a small footpri
nt, and they'll support comms, storage, and IO migration.
On the server front, PCI Express will let adaptors connect directly to the MCH
without a bridge, offering lower latency, lower cost, and fewer pins. Bandwidth
will kick off at 10Gb from launch day, while in the future vendors will offer
server modules which allow additional connectivity to be installed much like "
inserting a cartridge into a VCR".
Intel itself will have two chipsets supporting Enterprise PCI Express –
Lindenhurst and Twin Castle.

: 肯定还有3-4年才能淘汰AGP的显卡啦~~
: AGP的技术那么成熟~~

: : 如果ATI和nvidia出了,agp就被淘汰拉,这个时候难道intel amd via不动作?
: : 其实服务器也就是装几个RAID而已,市场肯定没有显卡的大.
