Acer Swift X 14 (SFX14-71G) review – going to a gunfight with a knife
Temperatures and comfort, Battery Life
Max CPU load
In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.
Average P-core frequency; Average E-core frequency; CPU temp.; Package Power
| Intel Core i7-13700H (45W TDP) | 0:02 – 0:10 sec | 0:15 – 0:30 sec | 10:00 – 15:00 min |
|---|---|---|---|
| Acer Swift X 14 (SFX14-71G) | 1.36 GHz @ 3.23 GHz @ 80°C @ 80W | 0.40 GHz @ 1.95 GHz @ 54°C @ 20W | 0.60 GHz @ 3.16 GHz @ 83°C @ 50W |

| Acer Swift Go 14 (SFG14-71) | 3.13 GHz @ 2.34 GHz @ 75°C @ 67W | 3.08 GHz @ 2.32 GHz @ 91°C @ 66W | 2.46 GHz @ 1.83 GHz @ 89°C @ 43W |
| MSI Pulse 15 (B13V) | 3.70 GHz @ 2.36 GHz @ 86°C @ 96W | 3.52 GHz @ 2.37 GHz @ 87°C @ 89W | 3.23 GHz @ 2.54 GHz @ 77°C @ 87W |
| MSI Vector GP77 | 3.86 GHz @ 3.08 GHz @ 89°C @ 135W | 3.75 GHz @ 3.10 GHz @ 94°C @ 128W | 3.24 GHz @ 3.00 GHz @ 81°C @ 90W |
Unfortunately, the Acer Swift X 14, and its 100W power adapter’s love-hate relationship with Intel Core i7-13700H’s P-cores can never be recovered. Apparently, the device prefers to run the E-cores to very high values, yet completely neglects the P-cores.

On the bright side, the RTX 3050 performs just as expected, managing to max out its 50W TGP budget.
Comfort during combined load
Even though it has only one fan, the laptop can become a bit loud. Plus, there is a noticeable coil whine. We shouldn’t skip the part where the entire keyboard gets very warm during gaming. Not to mention the part north of the keyboard, which runs at almost 50°C.
Battery
Now, we conduct the battery tests with the Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. This device has a 76Wh battery pack. It lasts for 10 hours and 50 minutes of Web browsing, or 8 hours and 56 minutes of video playback.
Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better
In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.

Thanks for the review. One question. Can the P-Core responses be addressed through software updates are is this a hardware issue?
