Embedded Systems

HP t5700

Released in early 2003, the t5700 was among HP's first PC-compatible thin clients, featuring Transmeta's low-power Crusoe TM5800 x86-compatible 128-bit VLIW microprocessor with independent 64 KiB instruction and data caches as well as a 512 KiB unified secondary cache. All tests are performed under Debian 9.8 on a system not specifically configured for benchmarking.

HP t5325

The t5325 is a miniscule low-power thin client unveiled by HP in late 2009, designed around a Marvell Kirkwood 88F6281 system-on-a-chip implementing a Marvell designed ARMv5TE-compliant "Sheeva" processor core clocked at 1.2 GHz with independent 16 KiB instruction and data caches and a 256 KiB unified secondary cache. All tests are performed under the HP "ThinPro" operating system, a lightly customized variant of Debian Lenny, on a system not specifically configured for benchmarking.

Laptops and Portables

Apple iBook G4 (Mid-2005/1.33)

The last and fastest of the 12'' consumer-oriented iBook G4 line, the mid-2005 model is built around the 32-bit PowerPC 7447a microprocessor fabricated by Freescale Semiconductor, then recently spun off from Motorola in the previous year. The 7447a is the final desktop iteration of the PowerPC 7400 'G4' microprocessor used by Apple in their systems, featuring two 32 KiB primary caches for instructions and data, a single 512 KiB on-die unified secondary cache, and some additional mobile-oriented features, such as dynamic frequency scaling and an on-chip thermal diode. As implied by the system model, the processor clock is 1.33 GHz.

Workstations

Apple Power Mac G5 (Late 2005/2.3DC)

The mid range of Apple's final generation of PowerPC-based professional systems, the 2.3DC was introduced in October 2005 and featured IBM's new dual-core 64-bit PowerPC 970MP processor, which featured two PowerPC 970 cores each with 32 KiB data cache, 64 KiB instruction cache, and a unified 1 MiB secondary cache. This system has a clock frequency of 2.3 GHz. All tests are performed under Mac OS 10.4.11, on a system not specifically configured for benchmarking.

HP VISUALIZE C3000 (9000/785/C3000)

A mid-range Unix workstation released in 1999, based on HP's indigenous PA-8500 microprocessor with 1 MiB of on-die data cache, 512 KiB of on-die instruction cache and a clock frequency of 400 MHz. All tests are performed under HP-UX 11.11 (11i v1) on a system not specifically configured for benchmarking.

Servers

Sun Fire T1000

The Sun Fire T1000 is an entry-level 1U rackmounted server released in early 2006 as one of the first systems to use Sun's radically multi-threaded UltraSPARC T1 "Niagra" microprocessor, derived from a SPARC implementation originally developed by Afara Websystems that features four, six or eight relatively simple SPARC V9 cores with individual 16 KiB instruction caches and 8 KiB data caches, a shared 3 MiB secondary cache and a single floating-point unit shared among all cores. Each core also has four threads, all sharing a single pipeline and a massive register file composed of 640 64-bit registers that allows for a thread's state to be quickly saved and resumed in a single cycle in order to maximize processor utilization in heavily multi-threaded workloads. The T1 utilized in the T1000 is clocked at 1 GHz.

All tests are performed on a T1000 with an 8-core UltraSPARC T1 running Solaris 10 10/09 with no specific configuration for benchmarking purposes. Because the ANSIbench makefile is not yet set up to build CoreMark with multi-thread support, all results are for execution on one thread only. Keep this in mind when interpreting these results, as the T1's single-thread performance can be incredibly weak, even weaker than many low-power embedded processors like the ARM9 chip found in the HP t5325 above.
