HD4350 is aiming at OEM market and 64bit too, it's quite obvious 530gt is targeting at the same market segments, so it's selling point must be performance per watt, not performance or powerconsumption alone.

take a look at this discussion thread in S3's official forum:

430gt can't beat HD4350, but its overclocked version - 440gtx does (review on pcper.com tells this). 530gt can achieve the similar score with much lower clock frequency than 440gtx did. so I agree that 530gt uses another optimized Destination chip. maybe reviews come up in next couple of days will tell us more about its difference to the previous 400 series.

Excalibur which the rumor says is 128bit and supports DX11, can't be out earlier than NV or AMD. if Excalibur can be out within half year lagging behind, that could be a great success, given its bad record of always delaying in the past few years!! :twisted:

i agree with CarstenS, don't know what the acronym stands for, actually it's meaning lessto guess the name.
it should be another memory hierarchy of storage system, nearer to the procesing engine than caches, and it's not small or it's meaningless to draw it separately in the architecture block diagram. so it's a pile of registers in form of Register File. no doubt about this.

but it should be of complicated control logic there also. it's the entrance for multiple stream processors with in one section, or varies processing unit within a stream processors, to load or store data from or to L1 cache. they must have to elaborately design the micro-architecture to balance the throughput and latency. I'm interested in their scheduling strategy among multiple requests at the same time. and look at multiple L1 to a single L2 path, same problem will happen there. As they claim their architecture to be scalable, it will become more challenging if scale up to a large chip with times of SPs. so they might do well in 64bit and entry level but when scaling up, much work need to be done there to keep it small and efficient.

that might explain why you can't expect S3 lauch mid- or high- end products soon.

shader units, what does 8(5D) mean ?

I think that means 8 shader units capable of 5 Dimensional Vector ops each ?

Yep, that's what CB denotes vector-based units with.
