Ook word de reden aangegeven waarom de nieuwe Thunderbirds niet compatibel zijn met met de huidige plankjes. Uitleg ontbreekt nog echter.":
While I am not very competent in reading the language of Goëthe (=German), I found some interesting tidbits in this c't article.First of all, it appears that the Thunderbird works with a "push and Pull" signal and the K75 works with a "Open Drain" signal. Feel free to enlighten me about this signal stuff, but it seems to be the reason why the Thunderbird does not work together with VIA's KX133 which only supports "Open Drain". AMD will produce 40.000 thunderbirds with "open drain" signaling, which will work happily together with VIA's KX-133 chipset, to make the motherboard manufacturers happy. AMD, we want some of those on the DIY market too
.
C't also states that whether the rumours that certain boards with the KX-133 (Abit, ASUS) will nevertheless work (thanks to a bios upgrade) remains to be seen, and will create a lot of confusion. [break] Verder in het artikel nog wat info over de Ali DDR chipset voor de Athlon; volgende maand zou het bedrijf de chipset presenteren. VIA ziet nu meer kans in de Pentium III markt en werkt hard aan haar Pro266 chipset met ondersteuning voor 133MHz DDR SDRAM:[/break] ALI, the other chipset company, will present a Socket A/Slot A chipset in june, and it is rumoured that this chipset will support DDR SDRAM!!
VIA seems to focus on the PIII market, and is readying a PRO266 chipset with support for 133 MHz DDR SDRAM (2.1 GB/s) for the PIII market. Ace's readers know that DDR SDRAM will not push the PIII's performance much higher, as the PIII's memory performance is crippled by the 133 MHZ GTL+ bus. As you can read here, 133 MHz SDRAM combined with the 200 Mhz EV6 bus delivers as much bandwidth as a 133 MHZ GTL+ FSB does with DDR SDRAM!
