6 published specifications differ · Updated · Step-up pairing across price tiers
Two genuine dual-boiler machines with PID and 58 mm commercial groups, approached from opposite directions. The Breville is a consumer appliance with a stainless dual boiler and a digital interface; the Rancilio is a commercial manufacturer's home machine with brass boilers, twin PIDs and soft infusion. The Breville publishes a price; Rancilio does not.
$1,700 · Semi-automatic
Stainless dual boilers, PID and a 58 mm commercial portafilter — the point where Breville stops using its own 54 mm standard.
$1,318 · Semi-automatic
Two boilers, two PIDs and adjustable 0–6 second soft infusion — the Silvia with the single-boiler compromise removed.
On the specifications both manufacturers publish, this machine has no clear advantage — the case for it is price and availability rather than hardware.
Rows where the two machines differ are highlighted. A row is only counted as a difference when both manufacturers publish the figure — an em dash against a number is a gap in disclosure, not a win.

Only one of these publishes a pump figure (15 bar). Either way the coffee sees roughly 9 bar, so this is not the specification to choose on.
