a64 vs axp?

[DumpALump]

OK I'm really curious now as what areas the a64 excels at?

I haven't seen any benchmarks that show the a64 totally dominating the axp, but have been told that. I've heard an a64 at 2.2ghz is faster than even a mobile at 2.7ghz.

Can someone enlighten me with benchmarks, scores, or even just tell me what areas the a64 is much better?

Just trying to figure out the best price/performance for overclocking.

As far as I am aware, the A64 will beat all except highly clocked Barton CPUs. Add in the onboard memory controller, and 64bit support, and I would say go A64 if you have the money.

... the part of hitechjb1's post you're looking for is:

A 754 512 KB L2 A64 + 250 GB motherboard is around $100 more (as of May 04) compared to a Nforce2 + mobile Barton, but in return, one gets a NEW system with the A64 technologies + 15-25% average gain over a Barton (at same frequencies).

A 754 1 MB L2 A64 + 250 GB motherboard is around $150 more (as of May 04) compared to a Nforce2 + mobile Barton, but in return, one gets a NEW system with the A64 technologies + 20-30% average gain over a Barton (at same frequencies).

With the price drop of AMD CPU anticipated next week as reported in this thread,
AMD A64 Price Drops Effective 07/26/2004
such price difference would be further reduced by about $50 - 80.

Benchmarks aside, I'd say in real life, Athlon 64 overclocked to just 2.2 GHz is a better option than the best of Bartons and if you look around, 64's overclock above 2.2 GHz quite often with the right equipment.


So in the end it comes down to overall system cost.

Cheapest mobile Athlon XPs do 'only' 2.4 now for $77.

While I saw everyday use improvement jumps when I sold a Pentium III CPU for enough $ to buy a 1700+ Palomino when it came out with a motherboard,
and I saw a nice clear improvement when I overclocked the 2100+ to 3x00+ speeds, (I got it from the first batches newegg ever had), the improvements have slowed down when I compare the 200-300 MHz gain mobile 2400+ gave me.


How would every day use improve if I jumped from 2.4 Barton to 2.2 or slightly higher Athlon 64? Is it worth the cost?


I’m guessing not, for me.

They now say that even the HL2 and Doom 3 games will be quite playable on worse systems than 2.4 GHz Barton and a GeForce4 Ti card.


My thinking now is that switching to DVD burning is the event that will cause the need for the next upgrade, but that's always been Intel territory and it’s hard to find out just how much DVD burning and video rendering is improved when comparing Barton to 754 and 939 and Intel...

hitechjb1, if you're reading this, that's a q 4 u,
1. Expensive high quality video capture card
2. What improvements would one see if one uses it in a Socket A system such as mine (to burn a few shows off of TV), vs. putting it in motherboards running CPUs expected on current roadmaps in the next year...

I don't have much experience in these area. I am capturing video using a Leaktek TV card, or firewire + digital camcorder.

If you want to burn DVD, video rendering while using the system smoothly, I would say a dual processor system or future dual core would be good.

Things that are related to video rendering, streaming, ... a high memory bandwidth system (with sufficiently large amount of memory) such as 939 would have an advantage.

Actually thread hijacking was not in progress:

We could have filed my questions under thread starter's 'Areas Athlon 64 excels at' opening question... but OK we'll start a new thread:
http://www.ocforums.com/showthread.php?p=2946453

please tell me there, if you would, did you do this with your old Socket A system and if so how has switching to 754 improved things for you in this area?

 

[DumpALump]

Thanks guys, very informative =)

And no thread hijacking occured cause a64 would be faster with encoding.

Least expensive 754 for general purpose, games
2800+/3000+ 754 newcastle (may be clawhammer) + board
~$250-280 (after july CPU price drop)

Least expensive 939 for video encoding, scientific computation
3500+ 939 + board
~$500 (after july CPU price drop)
