Clang Fights GCC On AMD's Athlon AM1 APU With Jaguar Cores

Filed under
Development
GNU
Graphics/Benchmarks

For this benchmarking we used the stock compilers available through the Ubuntu 14.04 "Trusty Tahr" archive, which provided GCC 4.8.2 and LLVM Clang 3.4 -- the current stable versions of each compiler. The CFLAGS/CXXFLAGS set were "-O3 -march=native" to optimize the generated code performance for this particular hardware. GCC 4.8 introduced AMD Jaguar support while LLVM Clang 3.4 followed with the support. GCC 4.9 will already land AMD Excavator (bdver4) support.

Drop cap display problem

On stories using a larger image at the top, the drop cap often appears down in the story abstract, instead of at the beginning of the text. If you provide an email address, I can send a screen capture shot.

Layout

Yes, it's an issue we see on smaller screen sizes. Maybe time to change the layout a bit.

  • The Best Graphics Card Brands For NVIDIA/AMD GPUs As A Linux Consumer?
    One of the most frequent topics I'm emailed about is any brand recommendations among NVIDIA and AMD AIB partners for graphics cards. For Linux users, is there a particular brand preference for graphics cards? The short story is, no, there isn't one particular brand when selecting either a GeForce or Radeon graphics card that a Linux gamer/enthusiast should go with over another AIB partner. Over the past 12 years of running Phoronix, there has been no single AIB partner that superbly stands out compared to the rest when it comes to graphics card AIB partner brands like ASUS, Zotac, HIS, MSI, etc. They all work under Linux, rarely the AIB differences extend beyond the heatsink/cooler and any default clock speed differences, and I haven't seen one that's over-the-top crazy about Linux. I also haven't seen any major partner consistently put the Tux logo or other Linux markings on their product packaging, let alone incorporate any Linux drivers onto their CD/DVD driver media.
