Is 850E Chipset slower than the new 875PE

Hi guys, anyone can help me on which is a better card. 850E is a discountinued model which will has been replace by 865 and 875. Which is a better technology, RDRAM or DDR-SDRAM? Which is faster in terms of information retrieval and games?

Thanks
 
Strictly speaking, RDRAM is probably the better technology, but it is on its way out. Who knows when it will make a comeback? Certainly not in its current form.

In any case, if you want support for the latest 800MHz FSB Pentium 4 processors with HT, you will need to buy a motherboard based on the i865/i875 chipsets, as the i850E won't support them.

Thanks for that but I still want to know which is faster? RDRAM PC800 which has a memory speed of 40ns or faster but what is the new DDR-SDRAM speed like? Or is it based on a totally different technology? I am currently using a 850E chipset running on 1 GB RDRAM with a 2.4GHz chip but still kinda feel quite slow. So what can I do about it to make it faster? Upgrade the chip to a higher speed? Sorry about the misunderstanding but actually I just like to know which is a better memory bandwidth not the card. Wondering why I need so high speed and ram? Well I do a lot of Photoshop work and it really sucks up a lot of memory when I am creating multiple layers of images. Thanks again if you can feedback on my questions! Hey anyone esle interested, please feel free to comment...............

Reformat. That should not feel slow!
Now, for photoshop, I believe a HT supporting CPU would work better (assuming your mobo supports HT, and your OS does), but you're then limited to the 3.06GHz P4 (not the P4C CPUs), and I personally don't know if the i850E allows you to use the PC800 at 100MHz and the FSB at 133 (which is what the 3.06GHz uses). But hey, the memory might just work at 133, too.

As far as the memory goes, yes, they are very different. The 865 and 875 are faster, but it has little to do with the memory itself (this site does happen to have a nice article about the 865 and 875 chipsets 🙂), but rather that the rest of the chipset has gotten performance boosts, and RDRAM has been left in the dust, as it never came down in price.

The performance boost it got was basically from having a 200mhz (effective 800mhz) bus. So, yes, the memory itself is a factor since you have to use dual-channel DDR400 in order to really take advantage of the newer CPU's with the 800mhz FSB. But if you run the 865/875 boards with a 133mhz FSB CPU (effective 533) just like the 850E, I doubt it would be any faster at all. If you have an RDRAM chipset (and memory) that runs synchronously with a 800mhz FSB, RDRAM would probably still be the fastest. But the 865/875 chipset does have some awesome features like gigabit LAN and Serial ATA integrated in the southbridge.

The 850E will allow you to use a 533 FSB processor and PC800 RDRAM (which runs at 100mhz or effectively 400mhz). Its not as fast at PC1066 RDRAM though.

I am not disputing that, but the same thing would have happened w/ RDRAM, if it hadn't been forced into nothingness, and allowed to speed on up. So using DDR vs. using RDRAM has nothing to do with the performance of the 865/875--consumers and DRAM companies had and have everything do with using DDR over RDRAM.
