Bosch Benchmark SHP9PCM5N Dishwasher vs Bosch 800 Series Dishwasher SGX78C55UC

Both are Bosch built-in dishwashers with CrystalDry and a third rack, so the real split is quietness, controls and flexibility. The Benchmark SHP9PCM5N is the quieter machine at 38 dBA, adds PowerControl and TimeLight, and offers nine cycles with more options through Home Connect. The 800 Series SGX78C55UC runs at 42 dBA with six cycles and the same core drying and rack layout. Owners of both rate them highly for cleaning and drying; the Benchmark is the step up if you want the quietest run and the most cycle choice, and the 800 is the sensible pick if those extras don't matter to you.

  • Choose the Bosch Benchmark SHP9PCM5N if you want the quietest wash, the widest cycle selection and app-based extras like Smart Cycle.
  • Choose the Bosch 800 SGX78C55UC if you want Bosch's core CrystalDry and third-rack package without paying for the quietest motor and extra cycles.

Questions and answers

Which is quieter, the Benchmark or the 800 Series?
The Benchmark SHP9PCM5N is rated 38 dBA and the 800 Series SGX78C55UC is rated 42 dBA. Both are quiet; the Benchmark is the better choice for open-plan kitchens where the dishwasher runs while people talk.
Do both dry plastics well?
Yes. Both use Bosch CrystalDry, which converts moisture into heat to dry plastics and cups. Drying performance is effectively the same on either model.
Is the Benchmark worth stepping up to over the 800 Series?
Step up if you want the quietest run, nine cycles, PowerControl and TimeLight. Stay with the 800 Series if you mainly want CrystalDry, a third rack and solid cleaning with a simpler panel.
Which has more room for tall items?
Both have three racks and an adjustable upper basket, so tall glasses and stemware fit in either. The Benchmark adds RackMatic adjustment, which makes raising and lowering the upper rack quicker.
Do both connect to an app?
Yes, both are Home Connect compatible. The Benchmark exposes more cycles and options through the app, including Smart Cycle and voice control.
Which lasts longer?
Both share Bosch's stainless steel tub and wash hardware, so service life should be similar. The Benchmark's AquaStop adds sensor-based leak shutoff, which is extra protection rather than a longer lifespan.
