Professional Performance: Linux

Built around several freely available benchmarks for Linux, Linux-Bench is a project spearheaded by Patrick at ServeTheHome to streamline about a dozen of these tests in a single neat package run via a set of three commands using an Ubuntu 11.04 LiveCD. These tests include fluid dynamics used by NASA, ray-tracing, OpenSSL, molecular modeling, and a scalable data structure server for web deployments. We run Linux-Bench and have chosen to report a select few of the tests that rely on CPU and DRAM speed.

Due to our limited testing time and other issues, only the i7-5775C was processed in our Linux tests. These should be updated for Part 2.

C-Ray is a simple ray-tracing program that focuses almost exclusively on processor performance rather than DRAM access. The test in Linux-Bench renders a heavy complex scene offering a large scalable scenario.

NAMD, Scalable Molecular Dynamics: link

Developed by the Theoretical and Computational Biophysics Group at the University of Illinois at Urbana-Champaign, NAMD is a set of parallel molecular dynamics codes for extreme parallelization up to and beyond 200,000 cores. The reference paper detailing NAMD has over 4000 citations, and our testing runs a small simulation where the calculation steps per unit time is the output vector.

NPB, Fluid Dynamics: link

Aside from LINPACK, there are many other ways to benchmark supercomputers in terms of how effective they are for various types of mathematical processes. The NAS Parallel Benchmarks (NPB) are a set of small programs originally designed for NASA to test their supercomputers in terms of fluid dynamics simulations, useful for airflow reactions and design.

Redis: link

Many of the online applications rely on key-value caches and data structure servers to operate. Redis is an open-source, scalable web technology with a b developer base, but also relies heavily on memory bandwidth as well as CPU performance.

    Why i7? The i5 is just as good when it comes to games, since hyperthreading doesn't do much for games. Reply

    We call those laptops. Passively cooled? That's normal htpc and abnormal niche PC user/gamer Reply

    100 watts is less than $80 usually a year if it is only when you are gaming. Just say no to ordering lunch like 3 days a year and you are good. :) Reply

    When AMD inefficiency costs an $80 bill, skip lunch it's all good...

    When an Intel or nVidia product is $8 more let alone $80, that settles the whole matter completely in AMD's favor, and proves once again AMD is the best bang for the buck....

    That's how AMD fanboys play it.

    I guess despite all the sickening propaganda of the amd fans, no one is listening nor buying it.
    AMD is dying and nearly dead, market share and share prices...

    What the AMD fanboys forgot is no one else likes being lied to, nor told what to do.

    I don't care about small differences in power consumption for home use either. But I do like the info to compare nodes. Reply

    as a gamer in florida, I care very much... gaming in the summer the heat produced is enormous and the central A/C is running overtime trying to keep temps down Reply

    They could put 8 cores in there instead of that GPU. Reply

    well we can dream.

    i could use more cores.
    i use heavy multithreaded applications and do heavy multitasking.

    yet i have to live with 10% better performance per cpu generation. :(

    haswell-e is the only choice when i want to upgrade.
    but it runs hot and i have no use at all for internal graphics.

    so why not making another CPU tailored for people like us?
    i mean intel makes enough different CPUs anyway.
