Benchmarks (http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_1278_6291%5e2003,00.html?redir=CPWS1A)


I would have liked to see Maya instead of XSI and Autocad as representative examples, or better yet along with.

However, based on these very preliminary results, if accurate, the MP2600+'s out perform the competitions 2.6ghz. part by a healthy margin at a little less cost.

I'll be testing one anyday now...xeon system is actually almost 50% done benchmarking...yay.

greg: as per my other post, i'll have access to a dual 2.8GHz dell precision 650 in a fortnight. if you want me to bench it, let me know.

Sure thing elvis. What apps you have avail to bench with? Make sure your using Win2k Server, or XP.

Why buy a Dell when you could buy a 3DBOXX for about the same amount of $$$?

hey GregHess , why W2K server instead of the pro?

Win2k professional will not be able to see the logical processors if hyperthreading is enabled. Only Windows 2000 Server and Windows XP have this ability...

In fact, if your using Win2k Sp2 and you enable Hyperthreading, the OS can't seperate between logical and physical processors, and will assign the first two processors it sees...which will be CPU #1 and its logical processor...thus greatly impacting performance to an extremely negative level.

This was solved in SP3, but 2000 professional still doesn't have the ability to see both physical AND both logical processors (AND use them) when hyperthreading is enabled.

This only applys to Dual Xeon configurations. Windows XP resolves this issue, as does win2k server.

Depending on your app of choice, hyperthreading can result in massive performance increases. In Max5 + Vray for example, you'll see upwards of 25% decreases in rendertime, as vray is smart enough to assign buckets to the logical processors, as well as the physical ones.

Thanks for the info,
That must be due to W2K pro reckons up to 2 procs instead of the 4 of the server edition aintit? (since im on MPs this has little or no interest to me :) Is there any other difference between W2K pro & server on a smp system?

sumatra,

Thats exactly right. Instead of giving win2k the ability to deal with the two logical procs, they just forced it to detect the two physical ones in sp3. It still loses the extra logical unless your running a win2k variant which can detect more then 2 procs.

I don't know too much about the differences between win2k prof and server to comment on them. (I'm not an MCSE guy)

i'll be benching the usual free spec benchmarks as well as the cinebench stuff. it'll certainly be running winXP pro with HT enabled.

i can't be arsed authing the max4 copy we have (it's a pain in the arse in australia as you have to ring the US) but i can run it in the 30 day trial mode to run specAPC. what's the status of spec APC under max5? we've got a flexLM/adLM server which means max5 is much easier to get up and running and benching.

i can also run some augi AutoCAD benchmarks if anyone's interested.
