The catch
Yamaha DGX-670
At 445 mm, the body is deep before you account for placement and accessories.
Side by side
The DGX-670 is the choice for singing, score display and multi-track recording. If the arranger piano has to be carried often or connected to a separate speaker system, take the XE20.
Before you buy
Listed instrument weights are 11.4 kg for the XE20 and 21.4 kg for the DGX-670, a 10 kg difference. The Korg is also 109 mm shallower, at 336 versus 445 mm. If you move an accompaniment piano between rooms or rehearsals, that combined change in load and depth can be worth more than choosing between 263 and 280 styles.
Where this comes from
Listed instrument weight: DGX-670 21.4 kg, XE20 11.4 kg. Depth before music rest: DGX-670 445 mm, XE20 336 mm. Accompaniment styles: DGX-670 263, XE20 280. This is a conditional workflow inference drawn from these documented inputs. There is no matched performance measurement.
The catch
At 445 mm, the body is deep before you account for placement and accessories.
The catch
Eight accompaniment parts take up part of the 12-track allocation. According to the manual, user-song overdubbing is supported, but twelve independent keyboard parts are not.

Yamaha DGX-670 vs Korg XE20, compared on listed instrument weight, depth before music rest and microphone input, plus the practice routines that decide the better choice.
Each is a weighted 88-key arranger piano for people who play with automatic accompaniment. Yamaha's recording and singing tools go up against Korg's lighter body and dedicated outputs.
Which one fits
Listed instrument weights are 11.4 kg for the XE20 and 21.4 kg for the DGX-670, a 10 kg difference. The Korg is also 109 mm shallower, at 336 versus 445 mm. If you move an accompaniment piano between rooms or rehearsals, that combined change in load and depth can be worth more than choosing between 263 and 280 styles.
The DGX-670 provides a microphone input and a 4.3-inch score display, whereas the XE20 has no microphone input in its connector list. When singing and following a displayed score happen in the same session, Yamaha brings those tasks together. If you have a separate singer's system, Korg's portability becomes attractive again.
On the XE20, the sequencer allocates four keyboard parts and eight accompaniment parts, and the manual supports overdubbing on a user song. The DGX-670 gives you 16 recorder tracks, which leaves Yamaha with more room when you need more than four keyboard parts. A simpler arrangement works on the Korg too, since you can still layer playing over a saved song. Do not read 12 total parts as 12 independent keyboard tracks.
Dedicated L/R outputs are on the XE20. For an analog output route, the DGX-670 uses its shared headphone output.

Yamaha, DGX-670
A score display, microphone input and 16-track recorder share one weighted piano in the DGX-670. If your routine includes arranging and singing, it makes sense, as long as you have a permanent spot for the deeper body.

Korg, XE20
In an 11.4 kg body, the XE20 has weighted keys and 280 accompaniment styles. Dedicated line outputs come in handy if you also use the piano with a separate speaker system.
Spec by spec
| Spec | Yamaha DGX-670 | Korg XE20 | In practice |
|---|---|---|---|
| Listed instrument weight | 21.4 kg | 11.4 kg | Work out the load you will be moving from the stated measurement basis, and then add the stand, case and accessories. |
| Depth before music rest | 445 mm | 336 mm | The music rest, cable route and comfortable playing clearance are all left out of bare depth. |
| Microphone input | Yes | No | Before vocal effects count for anything, a singing setup needs a documented input and a compatible microphone. |
| Dedicated line outputs | No | Yes | With dedicated outputs, the route to external amplification stays apart from the headphone sockets. |
| Internal recorder tracks | 16 | 12 total parts, including 4 keyboard and 8 accompaniment parts | Layered recording is supported by both. Compare how many parts are allotted to the keyboard, and don't treat all 12 Korg parts as independent keyboard tracks. |
| Accompaniment styles | 263 | 280 | Arranging and play-along sessions are where accompaniment patterns count, and not every piano lesson needs them. |
Trade-offs

If you move an accompaniment piano between rooms or rehearsals, that combined change in load and depth can be worth more than choosing between 263 and 280 styles.
Neither model fits. Manufacturer records contain no matched test for those outcomes. Try the instruments under the conditions you intend to play in.
