Dual Core Linux Performance: Two Penguins are Better than One

Multitasking Scenario 2: File Compression
This is also a very valid test on Linux, although most Linux users will use BZip2 or GZip, but BZip2 is more CPU intensive. Since BZip2 and GZip are both integrated into a typical SUSE desktop, it makes sense for us to just run it from the cmdline, shell script or via right click (we ran from a shell script).
- Open FireFox 1.0.4 and load all 5 web pages
- Open XMMS and start playing a Nine Inch Nails CD ripped to Ogg
- Open Thunderbird
- Import 260MB mailbox
- bzip2 -c a 130MB single text file and time the compression
Unfortunately we could not quite replicate this benchmark in the same manner Anand did during his previous analyses because we were not able to time the number of emails imported per second with reliable accuracy (which is why we do not have the second metric on this test). There may be vast differences between the number of emails imported per second between these processors. We will tone down the significance of this benchmark in our conclusion.

where is the pentium EE? :-)JGunther - Friday, July 1, 2005 - link
#4, it's 'cause Kris is writing the article. 'nuff said. ONCE AGAIN he's skewed the benchmarks by throwing the top of the line Intel dual core chip up against the entry level AMD chip. Nice job.Also, ditto on #7 and #12... way to criticize the AMD part for its price, Kris, without mentioning that the Pentium-D requires a mobo upgrade while the X2 does not.

#6 that's what i'm thinking.plus, i thought that with dma enabled, the cpu would not have to do too much work to burn a dvd

I look forward to some database server/web server tests.appu - Friday, July 1, 2005 - link
Kris, great work! You might want to consideramaroK (http://amarok.kde.org) as an equivalent
of iTunes under Linux, or even gtkpod. XMMS is
better treated as an equivalent of Winamp 2.x.

I have one question: why was the compile job on the x2 system only run with -j1? Not trying to flame you or anything, just a wondering...bob661 - Friday, July 1, 2005 - link
Kristopher Kubick,"At $558 you pay through the nose for the additional performance of the Athlon 64 X2 4200+"
That's the price for the P-D 840 not the X2 4200.

I think #7 has hit the nail on the head. One other large difference in the prices besides the memory is the extra $100+ spent on a 955x motherboard or a comparable nforce4 sli intel edition (not sure if these support dual core yet though). The price difference, as has been pointed out several time before, between the intel cpus and amd cpus is just about negated once you tack on the extra cost of the MB and memory.You could definitely choose a 945 MB and save about $100 but I have yet to see the pentium D benched on that platform, and I don't think there is an sli platform for intel that's available for under $225.
