Both the COM840 and XTX840 are said to feature the Core 2 Duo L7500 processor clocked at 1.6 GHz. Using the Intel GME965 chipset, both also have a 1 MB second-level cache and a 800 MHz front-side bus.
The Intel GMAX3100 chipset offers 384 MB of memory, eight fully programmable execution cores, and full DirectX 10 compliance. Ampro says this makes the modules "suitable for ultra-high-performance applications that require high-end graphics."
Apart from the form-factors -- one being compatible with the
COM Express standard, and the other with the
XTX specification -- there are some differences between the two modules, as noted in the specification lists below. For example, the COM840 has Gigabit Ethernet and RAM expansion up to 4 GB, whereas the XTX840 has 10/100 Ethernet and accepts up to 2 GB of RAM.
