Whats Faster, Athlon 1100mhz(200mhz bus) or Athlon 1000(266mhz bus)?

Whats Faster, Athlon 1100mhz(200mhz bus) or Athlon 1000(266mhz bus)?
The reason I ask is they are about the same price... Also, the KT133a chipset supports the 100mhz bus, right?
Thanks!

I'd take the Athlon 1GHz with the 266 FSB because the memory bandwidth (only when you use PC133 RAM) is higher opposed to FSB200. It's not that much, though. But I'm not sure if the 1.1GHz with its additional 100MHz can compensate this.

Somebody correct me if I'm BSing!

get whats cheaper and simply overclock to the highest FSB your system supports

the KT133A supports both 200 and 266 MHz FSB speeds. The KT133 only supports 200 MHz FSB. Make sure you know what you've got before you make an upgrade you will regret later. It might be more fun to get the 1.1 GHz T-bird and then see how far you can push the FSB (there is more room to grow because you are only starting at 100 MHz).

My take on it is speed of mhz is the power here, especially in the kt133a system...I think were the 1000 (266fsb) may feel close to the 1100 will be in conjunction with the ddr memory hence the c chips being called the ddr athlon chip. With pc133 ram I think either is fine. Many of the 200fsb chips when unlocked will do the 133 with lower multiplier anyways.

I think I have seen some appzs that enjoy the more fsb, but I am not sure to the tune of what and does it outweigh a 10 percent gain in speed...

200fsb chips work on kt133a....


I would try to get a axia 1000(266) tbird and oc the hell out of it...the newer 266fsb chips came later and their stepping seems to oc much better...if any of this is right or helps...

i just got a axia 1.2ghz from newegg.com

you think this thing is real good for o/c'ing? i already put it on 145fsb but only at 9x

I think they would be close.
I seem to recall the 266Mhz FSB versions having about a 5-10% performance advantage depending on the app. And the 1100 is 10% faster than the 1Ghz. So they would probably be pretty close.
Personally I'd go for 1000/266 to eek out a little more memory bandwidth for future use (that's assuming no overclocking...if you are overclocking it shouldn't really matter which you choose since you can adjust your multiplier and FSB with AMD chips).

 

[Duvie]

Many around here got some good gains with the axia and some of the new 5 letter stepping...I think I have seen many 1gig axia getting almost up to 1400 alone...I would think with some voltage adjustments yo should get to 1400...say like 9.5x148...

Faster for what?

In applications that depend more on memory bandwidth than CPU frequency, the 1000/266 would win. For applications that rely on CPU frequency (ie RC5), the 1100 would win.

The solution?

Buy a 1100/200 & overclock the fvck out of it.

...The 1100, of course<G>

That doesn't mean the 1100/100 system is faster than the 1000/133 would be, because system performance is dependent upon the subsystems and how good a job the mobo manufacturer did with layout and implementation. Were this not the case, all the benchmarks for mobos with a certain chipset would be identical at Anand's, at Tom's, and everywhere else, irrespective of manufacturer.

Yes, the 133a is backwards compatible with 100Mhz...
