AMD vs Intel: A Linux Bout

Posted by CmdrTaco on from the battle-of-the-titans dept.

CrzyP writes "AnandTech puts the latest and greatest AMD and Intel CPUs, including 32-bit and 64-bit versions, to the test in their first ever "Linux Desktop CPU Roundup" to see which performs the best in various Linux applications including database, compiling, rendering, encryption, and more. They suggest the Athlon 64 3500+ over the P4 560 for "balancing price and performance". Very informative!"

    So this latest benchmark suggests that HyperThreading doesn't do a whole lot. Is this the case on all unixy systems (ie: is HT geared more to Windows?) or is lacklustre performance on Windows the case as well?

    I'm leaning heavily to the AMD 64 stuff for my next home unixy machine, any arguments for the P4?

      No input re: M$ on HT'd cpu's.

      Under Linux I have seen various effects due to HT in the CPU. In the bad old (2.4 kernel) days dual Xeons would often run slower under relatively high load because the scheduler was agnostic of the fact that virtual cpu's share cache. I have also seen some sections of code which a)caches up nicely and b) is VERY heavy on FP math, give me about 1.8x the throughput by enabling HT. Seems the more a feature is hyped by marketing, the more likely it is that your mileage will vary greatly. Now if we could just get an OS/compiler that could use all the freakin' MMU's on a Power4 instead of just one .....

  2. Where's the 754s? by ameoba · · Score: 5, Interesting

    Any article that bases its conclusions on price/performance ratios that leaves out AMD's socket 754 Athlon64s is overlooking a major contender. Socket 754 chips generally cost far less than the s939 ones at comparable speeds and with the current generation of chips the dual-channel memory that s939 offers doesn't provide that much of a performance boost.

    Some might say that the s754 chips are an upgradability dead end but most people aren't upgrading CPUs without replacing the motherboard & RAM anyways. A s939 chip doesn't really get you much more upgrade headroom since there are no 939 boards with PCI-Express and DDR2 on them anyways...
