Sempron vs XP

[ausdog]

I have an Abit nForce2 with XP3200+.Would I gain much by going to Gigabyte nForce3 with Sempron 3100. Also I hear the XP3200 is discontinued.Did I buy a dog? Ed

 

[Ned_Flanders]

No, that system is OK - you wouldn't see any performace increase to justify the price. The minimum you would want to upgrade to is an NF3/4, and a socket 939 Amd 64 3200/3500 (Avoid semprons).

No you didn't buy a dog. AXP 3200+ is a quite good CPU, you won't gain much (in some cases none at all) by upgrading to Sempron 3100+

But doesn't the improvement from nForce2 to nForce3 (on the mobo) give a large jump by itself?

Can I direct you to Toms Interactive CPU charts?
Do the comparisons for yourself.. You may even want to consider an Intel if ur predominantly into multimedia stuff

The loving are the daring!

There are two versions of the sempron 1 is a athlon64 with half the cache and 64bit disabled the other is a thoroughbred B core Athlon XP just renamed! So you actually could be buying yourself the same CPU.

Nforce3 was made to support socket 754/939 CPU's it isnt necessarily any faster than the Nforce2, just made for different CPU's.

I was looking and comparing the nForce3 boards to mine on Sandra and I'm betting that the reason the nForce3 was showing so well was because it was running a 64 bit cpu.

No. It is not because it is a 64 bits CPU, it is because the 32 bit core of the Athlon64/sempron754 is much better than the core of old XP. Tu use the A64 in 64 bits, you need to have a 64 bits OS and 64 bits apps. And running those benchmark in 64 bits and comparing them agains the same benchmark in 32 bits would not be fair.

Running the benchmark in 32 bits with an A64 and comparing them with other 32 bits cpu will only show how improved and better the A64 core is, and that's what you are seeing with Sandra.

Better core, OD memory controller, improved BPU,.. is what makes the A64/sempron754 a better 32 bits CPU.. 64 bits is a plus when 64 bits apps will be available..

The sempron he is talking about is the sempron 754.. not the obsolete 462 socket a one ..

[ausdog]

No it wouldn't be fair.Looking at the copy of Sandra that I have, they include no Semprons and they do include Opterons which correct me if I'm wrong but aren't all Opterons 64 bit? They have only Opterons and XP's and they are all in the same list.Sandra needs to update...and make clear what is 32 bit and what is 64 bit.

 

[pat]

Opteron, Athlon 64, sempron 754 all use the same architecture. they are 32 bits CPU with 64 bits capability, except for the sempron that has no 64 bits instruction capability and smaller cache. They all can be benchmarked in 32 bits mode and the results will be fair.

Ok, I'll try to make it clear ..

AMD took a 32 bits architecture, fine tune it for efficiency, add the ability to execute 64 bits without downspeeding the 32 bits side ... That give the AMD 64 bitd serie. what about reading a bit at amd.com???

[ausdog]

But are they benchmarking in 64 bit or 32 bit? Look at the score under the only memory benchmark for an nForce3 3100. If what the other members say is true that a 3100 Sempron will benchmark about the same as an XP3200, why is Sandra showing it almost doubling the performance of the XP3200? And they don't show any benchmarks except for XP and Opteron.

 

[pat]

This is memory bandwidth ...not a real performance anyway, I gave up.. you should read the CPU faq, read amd.com,... and learn something, because, if you dont understand the answer, I see no point in continuing.. maybe somebody else will

sempron is no good.

 

[jammydodger]

Basically dude, you are not gonna notice any performance difference between a 3100 sempron and an Athlon XP barton core 3200+.

You would notice a performance difference when going from a 3200+ XP to a 3200+ Athlon64 but even then we are only talking 10-20%.
