The mainboard in the Wal-mart/Everext PC is a VIA Mfg. NO: PC2500E:
ClubIT Price: $59.99:
The cpu is a 1.5GHz VIA C7-D:
sixteen pipeline stages
MMX, SSE, SSE2 and SSE3
128KB full-speed exclusive L2 cache
The chipset is a VIA CN700:
and supports up to 2GB of DDR2 533/400 with a maximum memory bandwidth
The memory controller for the C7-D is in the chipset like the Intel's
and not in the CPU's like AMD. LinuxBIOS support for the C7+CN700 was
just posted earlier today.
There is an Intel Mainboard+CPU D201GLY that is only priced at $10.00
more than the VIA board at $69.99:
featuring a Celeron Model 215 1.33 GHz CPU:
Two 32-KB L1 Caches
512-KB L2 Cache
FSB bandwidth of up to 6.4 GB/s at 533MHz
and SiS SiS662 chipset:
1GB DDR2 533MHz 4.2GB/s max. bandwidth
Intel D201GLY $69.99 at:
Another inexpensive option with higher performance are the SiS761GX
mainboards. Now with LinuxBIOS support!
Still no x11, dri, OpenGL drivers yet though (hint, hint SiS). Not
really a problem for clustering though.
2000/1600 mega-transfers per second - Hyper Transport
Socket AM2 Sempron processors
Memory bandwidth up to 12.8GB/s with Dual Channel DDR2 800
SiS761GX mainboard + Sempron CPU for $49.99.
ECS GOAL3+ AMD Sempron 3000+ 754 SiS 761 GX Micro ATX Motherboard/CPU Combo
3.2GB/s 400MHz DDR
1600MT/s system bus
only socket 754 but the AM2 versions are out soon.
For price/performance on the low cost end the AM2 Sempron + Sis761GX
will be better than Intel Celeron + SiS SiS662 and also the VIA C7-D +
The VIA C7-D cpu's consume much less power (only 20W maximum) than
either the Intel Celeron-D (65W) or AMD Sempron(45-62W). It depends on
how much you pay for power (and how long), floor space, enclosures, hard
drives etc. to be able to compare the total long term/lifetime of the
