IMB-1003 vs IMB-150

ASRock Industrial’s IMB-1003 Mini-ITX motherboard is directly based on their hugely popular IMB-150 Mini ITX motherboard solution, which has sold in the many thousands per annum since its release in 2013.

Providing exactly the same form factor and location of I/O (and the majority of other constituent components, too) the IMB-1003 offers improved performance in the same compact and space-efficient package, with its Elkhart Lake J6412 SOC providing an improved single thread performance of up to 53% efficiency over that of its J1900 counterpart; the N6415 Quad Core SKU provides processing speeds up to 3.0GHZ @ 6.5 W TDP.

The IMB-1003 also supports 4 times more memory (2 x 260 pin SO-DIMM DDR4, 3200 MHz – up to 32GB in capacity.   With the IMB-1003 providing identical input/output (I/O) to that of the  IMB-150, the IMB-1003 is an ideal replacement or considered upgrade path if you’re already utilising the IMB-150 and are contemplating a future IPC upgrade where more system performance is needed, but are also aiming to make the minimum of disruption around physically redesigning your product to accommodate a newer motherboard solution.
