Athlon 1800+ in a KT133a vs KT 266a

[maleficus]

If I buy and Atlhon 1800+, what would be the speed difference if I run it:
a) In a Kt133a motherboard with 256mb of Pc133.
b) In a Kt266a with 256mb of DDR 266mhz.

My main concern is for gaming, how the different cofigs will affect performance.

The thing is Im from Argentina, and with the economical situation right now, its very difficult for me to obtain a kt266a mobo, and much more expensive, and I have to buy many of them.

The second one will give you around 20% more gaming performance, and often it is well worth the money spent. Yes go for a KT266A, not only for performance but much better stability than the KT133A.

heh
in a couple of weeks ill be able to tell you

planning on going from my 1200C @ 1400 in a kt133a to a kt333

planning on doing some inhouse benchmarks to check the difference out as i change

You're an embarrisment to nature you know that?

Look what I found, could this be right? Differences of up to 100% in Quake 3!!!!!!!!!!!!!
Here they are...
The second fps are from the kt266a... the first ones from the kt133a...

Screen Resolution ASUS A7V133-C, 512mb SDR RAM, KT133A Chipset EPoX 8KHA+, 512mb PC2400 DDR RAM, KT266A Chipset
640x480 - 16bit Colour 132.4 fps - 179.9 fps
800x600 - 16bit Colour 119.9 fps - 178.27 fps
1024x768 - 16bit Colour 84.5 fps - 169 fps

hmmm
dunno
looks a bit sus

i hope they were using the same graphics card
cauz at 640x480, where the traditional memory bandwidth tests are done, the difference is quite small.

anyway's, one will see the most benefit with memory hungry apps.

Not enough information in that write-up. What video card? Video clock speeds? He says he has PC2400 DDR memory. Is he running a 150mhz bus on the DDR system? What is the bus speed of the SDRAM system? Is the detail level the same for all resolutions?

Even if everything is equal (1333 mhz, 133mhz FSB, etc) I have to question some of those results. I have a Tbird at 1500 mhz on a KT133A board (Epox 8KTA3PRO). At 1024x768x32 I score 98 fps. That's with Quake III set at highest quality with the LOD slide to max. (With just highest quality set and the slide at the default position I score 110 fps). By the way, that's with a lowly Geforce2 GTS at stock speeds. Why is his score so low at 70.4 fps?

Granted my CPU is at ~1500mhz and bus is 142 mhz (at this moment). I'll set to 133*10 and post a couple scores but I guarantee something wrong the numbers in that article.

<b>Update</b>

Now, I am really skeptical. At 640x480 (texture slide at max) I get 171.1 fps in 16-bit (w/ 16-bit textures) and 164.4 fps in 32-bit (32-bit textures).

His 640x480 score is too low for a KT133A system. Low resolution scores are CPU dependent, not video card dependent. His score should just about match mine no matter what video card at this low resolution. Something is configured wrong on the KT133A system. I'd bet money the Via 4-in-1 drivers aren't properly loaded or the system is running AGP 1X.

Aceshardware.com has a very detailed article on upgrading from a KT133 platform. I think it does a good job showing the merits of various upgrades. Don't be put off by the Duron at the starting point. You will still find really good information.

Here's the link.

I know, they look very suspicious to me too, and I think he doesnt mention the video cards used. Anyway in other sites I have seen the diference is between 16 and 20%
