Released in early 2003, the t5700 was among HP's first PC-compatible thin clients, featuring Transmeta's 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. One of the Crusoe's dual on-die memory controllers is directly interfaced to 256 MiB of 266 MT/s DDR memory through a 64-bit wide data bus. All tests are performed under Debian 9.0.3 on a system not specifically configured for benchmarking.

Announced at CES 2010 and launched on Verizon Wireless on March 2010, the Pre Plus was an updated version of Palm's innovative Pre smartphone with double the RAM (512 MiB) and storage (16 GiB), as well as a new touch-based gesture area rather than the previous home button. Like the original Pre, the Pre Plus is designed around Texas Instruments' OMAP3430 multimedia processor featuring an ARM Cortex-A8 core clocked at 500 MHz with independent 16 KiB instruction and data caches as well as a unified 256 KiB second-level cache.
The Pre Plus features 512 MiB of 400MT/S LPDDR memory mounted directly on the OMAP3430 package and attached to its on-die memory controller via a 32-bit bus. All tests are performed under WebOS 1.4.5 with WebOS Internals' UberKernel allowing for greater range of clock frequency tweaking, but otherwise no benchmarking-specific configuration.
GCC 4.2.3, -O2, Palm default profile (500 MHz underclock)

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. The C3000's microprocessor is interfaced to the "Astro" chipset through a 120 MHz Runway+ bus. The particular system tested had 2,560 megabytes of SDRAM, also running at 120 MHz, and was not specifically configured for benchmarking. All tests are performed under HP-UX 11.11 (11i v1).
