CPU benchmarks??? - Intel P4

[David_L6]

These are the results I get when benchmarking the CPU's in BOINC Manager.

P4 550 (3.4 GHz): ~ 2770 Dhrystone (always slightly less than 2800).

P4 630 (3.0 GHz): ~ 2350 Dhrystone

Both of those are socket T, LGA 775. The 550 is in a mobo with a 925X chipset with 3 GB DDR2 533MHz RAM. The 630 is in a mobo with a 915 chipset with 2 GB DDR2 533 MHz RAM. Both have plenty of hard drive space. Settings are the same in BOINC for both.

Now here's what lead to this post......

Socket 478 P4 3.4 GHz Northwood: ~ 3500 Dhrystone (slightly more than 3500).

This computer has ample hard drive space, but less than the two above. It also has less and slower RAM (1.5 GB DDR 400 MHz) than the two above. However it beats the P4 550 in benchmarks every time.

The P4 Northwood and the P4 630 computers are hooked directly to router with cable. The P4 550 computer is wireless. Would that (wireless) make a difference in benchmark results?

What are the latencies on the DDR2 in comparison to the DDR? the boinc benchmark likes tighter latencies.

Ah yes. the good old northwood. i have one of them at home. rare chip pal. I'll be running it again tonight after I ship off the 3.4 gallatin ..... to fund the C2D rig.

I don't know. I'll have to check on that. It's probably not very good. Just cheap RAM (Crucial and stuff I bought off of eBay). Thanks for the tip about BOINC liking tight latencies.

that may be optied?

my prescott 530 3.00Ghz LGA775 gets ~2000 odd dhry, so that is about right for the 630...

(off topic, is the only difference between my 530 and your 630 EM64 support?)

I don't understand that question. ???

The only difference between your 530 and my 630 is the line 2 cache. The 630 that I have doesn't support EM64T. The 530 has 1MB line 2 cache and the 630 has 2MB's. The line 2 cache does make a slight difference. I benchmarked a 570J and a 670 in the same computer using PCMark05, 3DMark05, and 3DMark06 and the 670 came out ahead overall everytime. (That was with both CPU's and the 7800 GTX at stock timing.) The 570J beat the 670 in two or three tests but overall the 670 always came out on top.

it may be optimised, ie, using the optimised boinc files, giving it use of the SSE2/3 instructions, and so increasing the benchmark score.

although, that would still seem a little low for an optied p4, and i think when i was running rosetta, with the optimisations, i was hitting at least 5k dhry.

Argh you had one, i been hunting one of these for ages for my shuttle htpc rig which is a wcg cruncher 24/7 too
using a 24.c northy at 3.12ghz water cooled Passive (big Rad)

hmmmm I may be selling it sometime... don't hold the breath though. They still cost €150-200 on ebay. I sold the Gallatin for .... $500 w/o shipping last week! Movieman will vouch on that one!
