DAte uno sguardo qui, non sembra per niente male, vero?
Perdonami, che c'e' di nuovo rispetto al 745?
Sbaglio o e' una revisione veduta e corretta del 745?
Io aspetterei il SiS 748...

> Io aspetterei il SiS 748...
Io anche , ma non uscirà mai perchè non esiste...la roadmap sis parla
chiaro.
Cmq euste sono le specifiche:
The SiS746 Host & Memory & AGP Controller integrates a high performance host
interface for AMD Socket A processor, a high performance memory controller,
a AGP interface, and SiS MuTIOLT Technology connecting with SiS963 MuTIOTL
Media IO. The SiS746 Host Interface features the S2K complaint bus driver
technology to support AMD Polamino, Morgan, Athlon/XP, and Duron processors.
It also supports the AMD PowerNow!T dynamic power management technique. The
Memory Controller can support DDR and offer bandwidth up to 2.7GB/s under
DDR333 in order to sustain the bandwidth demand from host processor, as well
as the multi I/O masters and AGP masters. The memory controller also
supports the Suspend-to-RAM function by retaining the CKE# pins asserted in
ACPI S3 state in which only AUX source delivers power.
The AGP interface can support external AGP slot with AGP 2X/4X/8X capability
and Fast Write Transactions. A high bandwidth and mature SiS MuTIOLT
technology is incorporated to connect SiS746 and SiS963 MuTIOLT Media IO
together. SiS MuTIOLT technology is developed into three layers, the
Multi-Threaded I/O Link Layer delivering 1.2 GB/s bandwidth to connect
embedded DMA Master devices and external PCI masters to interface to
Multi-Threaded I/O Link Layer, the Multi-Threaded I/O Link Encoder/Decoder
in SiS963 to transfer data w/ 1GB/s bandwidth from/to Multi-Threaded I/O
Link Layer to/from SiS746, and the Multi-Threaded I/O Link Encoder/Decoder
in SiS746 to transfer data w/ 1GB/s from/to memory sub-system to/from the
Multi-Threaded I/O Link Encoder/Decoder in SiS963.

Seguirą a ruota il 746DX versione con supporto memorie DDR 400
Speriamo

Io anche , ma non uscirą mai perchč non esiste...
E' un'indiscrezione letta su OCworkbench...
evidentemente devono mettere fuori prima i 735/745/746 ;)
In quest'immagine:
http://www.sis.com/images/products/diagram/746.gif
capisco che il SiS 746 dovrebbe avere queste caratteristiche:
- Support AGP 8X/4X/2X Interface
- ATA-133 (finalmente, se ne sono accorti che c'erano HD ATA133)
- IEEE1394e (questa sarebbe interessante; ma sara' disponibile?
  anche il SiS 745 la implementa ma non si capisce perche' non  
  l'abbiano resa disponibile - conferma che il 745 e' stato un 
  test chipset....)
- USB 2.0/1.1 
Invece poi dalla descrizione testuale:
http://www.sis.com/products/chipsets/oa/socketa/746.htm
Non ritrovo quello promesso nell'immagine...

 Non ritrovo quello promesso nell'immagine...
A me sembra corrispondere perfettamente anche perchè il 746 è formato da un
north bridge e da un south bridge in coppia, le key feature si riferiscono
solo al
north (il 746)...e non al south.
