yes, but your getting a noiseless case. Which, if needed, people will pay for.

:takes out soundproofed foam:

Great idea, as my PC sounds like a jumbo jet! but £800.... oh well! Maybe next year LOL!!

Then people should'nt buy 35627346283 billion case fans (or indeed, a case that IS a fan) and it wouldnt be so noisy =)

The reason A64s are so good for games and P4s so good for media editing/encoding and other such tasks is because of pipelining. There are four basic steps to processing a CPU instruction. First of all, the instruction needs to be fetched from the memory or the CPU cache. The instruction is just a binary value which needs to be decoded so that the CPU knows what it is and what it needs to do with it (this is the second stage). The third stage is the execution of the instruction and the fourth and final stage is storing the result in the correct location in the memory so that the program can continue. In older processors, one instruction would be handled at a time. It would go through each stage in turn and the result would be stored before the next instruction could be fetched.

Pipelining is found in modern processors and means that as soon as one instruction has reached the second stage (the decoding) the next one will be fetched from memory. The instructions will then move along in line so as soon as the first one reaches the third stage, the second goes to the second stage and a new instruction is fetched and so on and so forth.

There is a problem with pipelining though and that is program branches. As most programs are not linear sets of instructions the outcome of one instruction may require the program to jump to another place in memory and continue from there. The problem is that the pipeline will be full of linear instructions and therefore will need to be flushed and filled again with the new set of instructions. I think you can see where this is going now. The deeper the pipeline, the longer it will take for the new instructions to filter through and start producing results.

Pentium 4s have deep pipelines so the penalty for not predicting that a branch will occur will be far more severe than a CPU such as the Athlon 64 which has much shallower pipelines. This is why P4s will excel at media encoding because all that is is just a bunch of linear instructions, they're set out, the program isn't going to jump from encoding one part of a song to converting an entirely different part. The majority of software you come across will be more.. um.. "branchy" so a chip with a shallower pipeline such as the Athlon 64 will benefit.

Hope it helps.


Ever thought about going into the teaching profession? You just summarised in less than page what a tutor took 4 weeks to explain.

I would go for A64 because thats what i want but im skint.

that no noise case could be handy but man it looks awful.
The price looks more awful m8 :( but i agree, it would be nice to have a soundproof case seeing as mine is so freggin old and makes the sound of a helicopter, or a machine gun :agm:

Well Urban did sort of say this before - but WHY is it so?? looking at the link i posted quite clearly shows the P4 outstrips the A64 on most tests. I suppose you could argue that the A64 can do 64 bit OS etc but XP 64Bit is Kinda BETA still (no drivers) and I thought the whole point of 64bit was to get over the 4 gig ram limit yet the boards only feature 3/4 slots at most - I just dont get it tbh.

Tom’s hardware is bias’d, which is why I stopped reading them about 3 years ago.

As for A64 doing 64bit, the P4 6xx also supports 64bit and drivers have come a long way, including many official drivers from maufactuers. As for ram limits, stick to 32bit where evertything is the same.

As for HC’s comments, pipelines are indirectly responsible only for the fact that they allow for a higher MHZ output, although AMD does quite well with a lower pipeline number. When it comes to things as media encoding, P4 does well because it purely has more MHZ and most of the time AMD’s 9 operations a clock cycle per Intel’s 6 is not enough because the encoding doesn’t use it’s full potential, it needs raw speed.


[quote[Thanks for that Info Holy Cow and Bio, you can understand my wondering when I trawl Benchamrking Sites and see the A64 only really Excells at games. No matter which one I bought anyhow it would be fast, Games I am not fussed about 100%, all the games I have ever played so far are fine at the res my monitor can support (1280x1024) - you tend not to worry about the odd Jaggy line when bombing about in a FPS game tbh.

At the moment it looks like a A64 3800 with GeForce 6600 seems the best option. [/quote]

Well, when it comes to games I have NEVER seen a P4 even come close to A64 power, but then again this is well known, AMD beats the crap out of Intel when it comes to games.

or wait about 2 months and they wont be so expensive

Actually they will be still expensive for give or take 6-9 months. As illustrated by today’s cards.





As for that motherboard choice demonic, drop it like a rock. If your going AGP you want the MSI Neo2 Platinum. If your going PCI-E, you want any DFI NF4 board.
