ATI RADEON X800 XT & X600 XT PCI-E Performance Preview

Here is something to read. Forums have been slow lately.

PCI-E seems to be a bit faster in some benchmarks but not buy much.

interesting, AGP seems to actually outperform PCI-E in some cases. woo future!

Maybe its me but they ****ing suck big time.

Hmmm..... I was actually getting quite woried about upgrades at the moment. Bu PCI-Express does not really increase performance that much. I mean... obviasly it does. But not by like over 50% which i was expecting x8 and x16. Kinda would make sense to a noob.

I am going to have to think about what gfx card I should buy.

You guys do realize they were tested using different Motherboards, Sockets and Chipsets, right?
They are not apples to apples.

AGP to PCI Express still won't be a huge differencel. It was always about what to do for future gfx card upgrades.I bet it's just that the new platform that is to blame when they show PCI Express falling short of AGP. Refer to my Pentium 4 thread and the link for more on that.

I still think the idea of PCI Express on an Intel platform is partly flawed.
PCI Express talks up and down at the same time to a Front side bus which talks only one way. If it wants to talk to the CPU then it may have to still wait just like the AGP would have had to.

I want to see PCI Express on an A64 platform. PCI-E talking up and down to a HT link to the CPU up and down at the same time. Granted we could be only talking about 1-4 FPS improvment here. But they don't have a new sucky CPU taking over their new Socket either.

i just glanced over the benchmarks quickly but it looks like the PCI wins in the more dx9 heavy benchmarks (halo). But then again What about farcry thats dx9 and the PCI didnt win in that.

The X800 owns everything, but the X600 is barely a difference.

well, another thing to think about is nVidia's accuasations that thier chips jsut have a pci-e bridge "attached" to the standard agp bridge, whch would limit it to agp 8x speeds.


but that's what nvidia says.
