AMD64 Windows vs. Fedora vs. SuSE benchmarks
Illissius writes "AnandTech just posted a review comparing 32- and 64-bit performance on both Linux and Windows. They focused on what is available out of the box without having to compile anything seperately - unfortunately, 64-bit binaries weren't available for most of the Windows benchmarks. To save people the pain of RTFA, there's a very tangible gain moving to 64-bitness, Linux wins some (MySQL, UT2004), and Windows wins some (rendering, RtCW)."
Windows = Desktop and Linux = System ?
How new !
That this is a test for Gentoo. 64bit optimization! WHOOO!
UT2004 is a must in any server worth it's salt.
As a Gentoo user what really stands out to me is that this test was clearly biased away from Linux. If the reviewers had been serious they would have used an optimised distributions such as Gentoo, which would have taken far fuller advantage of the extra 32bits in each register to provide a much fuller experience, more than any current Linux distribution possibly could.
It really saddens me to see that people go out of their way to spend so much money on such expensive hardware and then squander their investment by running barely suitable software on it. To me, an extra 0.1% performance increase, even if I am only imagining it to be faster, is certainly worth one day a week recompiling all of the latest packages from source code. Even if I do occasionally get my CFLAGS in a muddle!
I think I speak for Slashdot when I say that Gentoo is the only sane option for getting the most from your hardware!
Just the fact that you're running a 64 bit system gives you the sense that everything is faster.
Besides, 64 being twice 32 justifies the upgrade cost...
What factor of raw "speed" faster would a 64bit processor be over a standard 32bit processor of the same clock-speed.
Clearly, 64 bits would be twice as fast as 32 bits. Not only that, but space for 64 bits means that you can use bigger bits for all of your old 32-bit applications.
I cook my Thanksgiving turkey at 900 degrees to shave the cooking time in half...
Uhm, you didn't READ the graphs...
Some said Lower Is better ( Usually test exec time )
Others said Higher is Better ( Usually FPS for the games )
And in each case, the 64 bit proc did do better.
Not considering possible discrepancies with SMP performance, the relative performance with Athlon 64s and Opterons should be exactly the same, as the architectural differences are minor - the Opteron has more cache and uses registered ECC memory. There's also a variant of Athlon 64s which only have single channel memory (socket 754), but again, all of these are for the most part minor 1-2% performance differences and shouldn't affect the big picture.
As for SuSE vs. Fedora, do note that they didn't actually recompile anything, which could change the picture significantly.
Work is punishment for failing to procrastinate effectively.
You're right, that is OBVIOUS! Nope. Just poking fun, great summary post of the technology.
A 64-bit processor has an upper limit of about 18 million terabytes... (32-bit = 0.0043 terabytes... 64-bit = 18,000,000 terabytes)
I think 18,000,000 TB should be enough for anyone.
I just don't trust anything that bleeds for five days and doesn't die.
Just wait until the Windows following Longhorn is released...
Stupidity is an equal opportunity striker.
