About BogoMips

BogoMips is a simple "busy doing nothing" pseudo benchmark, based on the busy-wait loop calibration used in the Linux kernel. While not much of a performance indicator it does give a feel for relative performance when comparing systems of the same architecture.

For more information about BogoMips see:

BogoMips Results

The "Notes" describes the source of the BogoMips score, on Linux and Linux-based systems this will be from the processor information in /proc/cpuinfo or using the value reported during boot and recorded in the system logs. For other systems the BogoMips score was obtained using one of the standalone BogoMips implementations (usually Jeff Tranter's BogoMips 1.3).

That is quite a range, over many generations of processor architectures.

Emulated Systems

These are just to give a general idea of how emulated systems fit into the table above. Since there is emulation involved, scores are often going to be variable, very dependent on system load and the underlying system performance. So don't take any of this as gospel...

AlphaVM Free

Emulation of various Compaq and HP AlphaServer and AlphaStation systems. For illustration I'm using a selection of machine profiles that emulate different revisions of the processor and run at different speeds.

For a free version of the emulator, which doesn't provide accelerations for the processor emulation, these figures look really good.

FreeAXP

Emulation of an DEC AlphaServer 400 4/166 on MS Windows 10 running on an Intel i7 860 with 16 GB RAM:

The figure of 150.00 BogoMips is very consistent, suggesting that the FreeAXP attempts to replicate instruction timing and thus gives deterministic results.

QEMU

The system and user-mode emulator QEMU provides many system emulations. Here we'll look at the performance of the system emulation of some of the more common vintage systems running the operating systems associated with them.

For these tests I'm running QEMU 5.2.0 on a Debian Linux 10.9 (buster+backports) VirtualBox guest on MS Windows 10 host on an Intel i7-860 with 16 GB RAM (that sounds complicated):

Notes:

  1. Since the 3.6 series kernels, Linux for ARM has directly derived the BogoMips result from a system timer frequency. This avoids issues with CPU frequency scaling on these processors, but means the BogoMips figure does not reflect performance.
  2. During the 2.6 series kernels, Linux for PowerPC changed from calibration against a real-time clock, to calibration against a system timer, to directly deriving the BogoMips result from the system timer frequency. This avoids issues with CPU frequency scaling on some of PowerPC/POWER processors, but means the BogoMips figure reported by later Linux kernels does not reflect performance.

The Linux scores are obtained by installing (or obtaining) a Debian Linux release supporting the platform (see Debian Ports, Debian Releases and Debian version history), since some platforms have been retired from mainstream Debian releases, this means some older kernels are used:

  • Debian Linux 3.0 (woody): kernel 2.4.18
  • Debian Linux 3.1 (sarge): kernel 2.4.27, supports i386 (Intel 80386 processors & clones)
  • Debian Linux 4.0 (etch): kernel 2.6.18, supports 32-bit SPARC (pre-UltraSPARC)
  • Debian Linux 5.0 (lenny): kernel 2.6.28, supports DEC Alpha, HP PA-RISC
  • Debian Linux 6.0 (squeeze): kernel 2.6.32, supports i386 (Intel 80486 processors & clones)
  • Debian Linux 7 (wheezy): kernel 3.2.0, supports 64-bit SPARC (32-bit userspace)
  • Debian Linux 8 (jessie): kernel 3.16.0, supports 32-bit PowerPC, 32-bit MIPS (pre-MIPS32r2), supports i386 (Intel Pentium (586) processors & clones)
  • Debian Linux 9 (stretch): kernel 4.9
  • Debian Linux 10 (buster): kernel 4.19, supports 32-bit MIPS (MIPS32r2 onward) and 64-bit MIPS in big-endian mode ('mips')
  • Debian Linux 11 (bullseye): kernel 5.10

In-official Debian ports were used for:

  • hppa: Debian Linux 10.0 (buster): kernel 4.16.0
  • m68k: Debian Linux 10.0 (buster): kernel 4.16.0; Debian Linux unstable (bookwork/sid): kernel 5.17.0
  • sparc64: Debian Linux 11 (bullseye): kernel 5.10.0, 64-bit kernel and user-space

PCem

PCem provides emulation of IBM PC, PC-compatible and almost PC-compatible systems. With options ranging from the original IBM PC from 1981, through to a Slot-1 based Intel Pentium II system from 1998.

From these results for Linux 2.2.14 and earlier, it appears the initial processor states are slightly different than that in the corresponding physical systems. After Linux 2.2.14 the kernel sets the processor(s) to their working states before calculating the BogoMips result, which changed the scaling of the results for Pentium and later processors.

MAME

While MAME is best known for its arcade machine emulations, it also provides emulations of a number of computer systems. In particular MAME currently provides the only emulations of Silicon Graphics Inc. systems capable of running IRIX (see "A guide to running IRIX 6.5.22 in MAME"). MAME currently provides emulations of an SGI Indy R4600 100MHz and a SGI Indigo2 R4400 150MHz

MIPS R4600IRIX 6.5.22100?bogo-1.3
MIPS R4400IRIX 6.5.22150?bogo-1.3

Looking at the scores in BogoMips mini-Howto, regular MIPS processors appear to give either: approx. half clock speed for R4400 and earlier, or approx. equal to the clock speed for R4600 and later. Note that the MIPS R5900 used in the Sony Playstation 2 gives a higher BogoMips score than this would suggest, likely due to the customization present in the processor.

MAME attempts to emulates the hardware as fully as possible, allowing original software to be used, but this introduces overheads that can impact the performance of the emulated system. In the case of the Indy and Indigo2 systems MAME claims performance of about 15% and 10% of the original hardware on our test system, and comparing the obtained scores with those in BogoMips mini-Howto this looks to be the case... ?

GXemul

The GXemul emulator supports a range of systems with an emphasis on MIPS base systems.
