I'm thinking of switching my P4 3.0c and IC7-Max3, for a S939 3500+ and ASUS mobo. My 3.0c runs at 4GHz 24/7 on air, but I want more performance, could I get this from the 3500+? Would the 3500+ out-peform the 3.0c @ 4GHz? I really would your opinion as to what you think, keep the 3.0c...or go S939 A64?

BTW: Since all of the S939 chips have only 512K cache, would it be better to go 754 and get a 3400+ with 1mb cache and a NF3 250 board?

I can answer the BTW part. A socket 939 would be alot better off performance wise than a 754 because the 754 only has single channel memory whereas the socket 939 has dual channel memory. It you want a 1mb cache you could get a 939 FX-53.

I don't see what sort of logic you're using to make this conclusion. 939 boards cost on average $100 more than 754 boards, not to mention that the 3500+ costs a whopping $500, $300 more than the identically clocked S754 3200+... And not to mention that the dual channel doesn't really do anything other than make up for the cache deficit compared to the Clawhammers at best. Look at this and tell me if it's "alot better off performance wise." Let's do some research next time before posting, 'kay?

If you have a 4 GHz P4, personally I would hang tight. If you really want more performance, either socket of the Athlon64 will give you more, but you probably won't notice it outside of benchies.


Where's Sterling, btw? Somehow I'm too dumb to have heard of it... :eek:

Thanks guys. I'm really thinking of getting a S754 3400+ w/ 1mb cache. With a good NF3 250 board and working AGP/PCI locks, I hope to hit 2.6GHz with the chip on my H20 setup. S939 systems seem to be OC'ing alot better, but I think a 400MHz OC is reasonable for a good H20 setup.

There exist 939 motherboards no much expensive than 754 boards.

Are we ready for this, non PCI-e 939 system ?

MSI K8N Neo2 (nForce3 Ultra)

MSI K8T Neo2 (Via K8T800 Pro + VT8237) ~ $ 149
http://www.msicomputer.com/product/p_spec.asp?model=K8T_Neo2-FIR&class=mb

ASUS A8V Deluxe (Via K8T800Pro + VT8237), ~ $166
http://www.asus.com/prog/spec.asp?m=A8V Deluxe&langs=01
or
ABIT AV8 (Via K8T800Pro + VT8237), ~ $135
http://www.abit-usa.com/products/mb/techspec.php?categories=1&model=175
or
Gigabyte GA-K8NSNXP-939 (250 939, nForce3 Ultra) ~ $230
http://www.giga-byte.com/MotherBoard/Products/Products_GA-K8NSNXP-939.htm


3500+: ADA3500DEP4AW 1.5V (CG rev, FF0h) <- NewCastle 939, 512 KB L2, 2.2 GHz, x11, ~ $485/$495
or
FX53: ADAFX53DEP5AS 1.5V (CG rev, F7Ah) <- ClawHammer 939, 1 MB L2, 2.4 GHz x12, ~ $800


So the least cost 939 mobo + CPU would be around $620 - $661.


Some AMD roadmaps (may not be officially) show 939 mobile A64 may come out Q2/Q3 04. Cheaper 939 soon?

A64 Nforce3 Motherboards (754, 939)

A64 K8T800 Pro Motherboards (754, 939)

Since you are considering a 754 3400+, as of today, even if not waiting for CPU price drop,
for new build system, the total price different between
- a 754 3400+ and board and
- a 939 3500+ and board
plus memory, video card, ... the rest would be less than 10%.

The 939 system would be good for high memory bandwidth applications such as video streaming, rendering, scientific computations, ....

Both of 939/940 dual channel have 80% more effective memory bandwidth than the 754, hence they are always better in performance, especially for memory intensive programs such as video and image streaming, applications using spatially structured data as in scientific computation, up to 20-80% higher performance (e.g. PCmark02 memory test, Sandra memory bandwidth, Sciencemark Stream, many scientific programs). For video, image streaming, data needs to be refreshed constantly from the main memory (L3) to the on chip L2 via the memory bus as size of data >> L2 size at any given time. Under such situation, the high dual channel memory bandwidth delivers a marked performance advantage.
