<< The pentium 4 only has one FPU unit compared to 2 on the p3... how is that improved? >> This has more to do with the way the FPU is described then any real difference in the FPU itself. The PIII has separate add and multiply units, but both are issued instructions from the same port. As...

CZAR &quot;RDRAM should be used for low memmory consoles not for high end workstations&quot; You might want to drop by aces hardware (http://www.aceshardware.com/) sometime and try telling that to Aaron Spink. (He is part of the team designing the memory interface for the next generation...

I basically agree with everything you said, but there is one thing. << In addition, it means that the number of instructions for ILP decreases, because, when there are data dependancies, it goes to the reorder buffer to look for stuff to do that isn't dependant upon data in the pipeline. If...

<< I wish I was lucky enough to be in JEDEC conferences scribbling down discussions and passing it all off as my own work. It's a scam worthy of any naughty schoolboy. God-damn! >> Rambus work preceded JEDEC's by a number of years. Check out the patents. (I hate putting this in a thread...

Thanks for putting that in a link for me. I have also heard rumors of additional stages in the Mustang. Adding a stage should not be that hard. In theory it is as simple as putting in a latch. In practice you have to find a place that a latch could actually go. I think Intel added stages...

digitalalgorithm, soccerman, hans007 You all seem to not fully understand what pipelining does. In any logic circuit (MPU's included) the number of logic gates in series determines the frequency the circuit can operate (along with the frequency the gates themselves can operate at.) When you...

NTFS has a lot of initial overhead compared to FAT32 (several hundred MB if I remember correctly) This is why I specifically mentioned small partitions. It takes a lot of wasted space on FAT 32 to overcome this. (This is why I said &quot;may use less disk space&quot;) Why would NTFS not be...

NTFS allows you implement security that allows only specified users to access a file or directory.

FAT32 will be a little faster and may use a little less disk space (especially on a small partition). NTFS offers file security, and is much less likely to suffer from corruption then FAT32. Most of the additional features of NTFS are really only useful in a corporate setting, but I do find...

&quot;The one device per channel limitation is a design limitation of the Rambus interface itself. Think about it: Rambus is serial in nature-a single Rambus chip (device) can spit out 16 bits of data at a time on a 16 bit bus (channel).&quot; I disagree. The number of open banks and therefor...

This is a little unclear. This would make sense since it can only support 8 open pages and one chip can have as few as 8 open pages, but I do not know if the pages can span more then a single chip. This isn't that important since it is the number of open pages that count.

On the contrary it would be a limitation of the chipset. The i820 only supports 8 active pages total. RDRAM supports either 8 or 16 open pages per device. The i840 supports at least 32 open pages.

Power management doesn?t kill Rambus performance, it just gives away an advantage that DRDRAM should have. It limits the 820 chipset to 8 open pages total, but this is still more then the 4 SDRAM is limited to. Read here. http://www.realworldtech.com/page.cfm?ArticleID=RWT112299000000 This...

Much of the latency of DRDRAM comes from the way it is used in PC memory. (DRDRAM uses the same DRAM cells as SDRAM so at that level the latencies are the same.) For small embedded devices with memory located close the processor and soldered directly to the board Rambus can get very good...
