The Qualcomm Snapdragon 8cx processor beats AMD in this race for being the first 7nm PC processor. But here the thing does not end, in the last few hours we are seeing the first benchmarks of this ARM chip, which slightly exceeds an eighth-generation Core i5 CPU Intel.
Qualcomm will compete strongly in the portable market with its Snapdragon 8cx chip
Qualcomm first showed off its 8cx processor at the Snapdragon Technology Summit in 2018, but at Computex 2019, they're showing what it's capable of. The company showed some benchmark numbers using PCMark 10, demonstrating its superiority over Intel's proposal.

Test and performance equipment
For all tests (Performed by Toms Hardware) a Qualcomm Snapdragon 8cx reference equipment with 8 GB of RAM and 256 GB of NVMe storage was used together with Windows 10 May 2019 Update (1903). The competing PC (which looked like a Dell XPS 13 on some slides) had an 8th Gen Intel Core i5-8250U, 8GB RAM, 256GB NVMe storage along with Windows 10 October 2018 Update (1809).
In the Office app benchmark, Qualcomm 8cx came out slightly ahead of the eighth-gen Core i5 CPU overall, though it didn't win in all tests.
| PCMark 10 | Intel laptop (Expected) | Qualcomm 8cx (Expected) | 8cx, Run 1 | 8cx, Run 2 |
| Total | 3, 894-3, 970 | 4, 039-4, 139 | 4, 296 | 4, 356 |
| Excel | 4, 334-4, 627 | 3, 925-4, 141 | 3, 929 | 4, 083 |
| Word | 2, 943-3, 089 | 3, 499-3, 609 | 3, 841 | 3, 823 |
| PowerPoint | 3, 688-4, 145 | 3, 780-4, 250 | 4, 375 | 4, 464 |
| Edge | 4, 401-4, 4599 | 5, 032-5, 278 | 5, 163 | 5, 168 |
The graphical test consisted of 3DMark Night Raid, which has a native version of ARM. In these tests, the results from Qualcomm and UL showed that the Snapdragon 8cx Adreno 680 integrated graphics outperformed those of the eighth generation Intel Core i5:
| 3DMark Night Raid | Intel laptop (Expected) | Qualcomm 8cx (Expected) | Snapdragon 8cx, Run 1 |
| Overall | 5, 047-5, 055 | 5, 710-5, 815 | 5, 841 |
| Graphics Score | 5, 172-5, 174 | 6, 138-6, 266 | 6, 251 |
| Graphics Test 1 | 21.45-21.49 fps | 24.84-25.31 fps | 25.22 fps |
| Graphics Test 2 | 29.43-29.47 fps | 36.21-37.10fps | 37.05 fps |
| CPU Score | 4, 431-4, 483 | 4, 093-4, 133 | 4, 261 |
Qualcomm's new chip provided the expected scores for both the Intel laptop and Snapdragon benchmark unit. Here the 8cx performed better in each of these tests, which has been a benefit of the ARM chips, but it should be noted that the Qualcomm design has an FHD display, while the competitor had a 2K panel, so things were not so even, because a 2K screen consumes more battery.
Qualcomm 8cx battery life
| PCMark 10 - Autonomy | Intel laptop (Expected) | Qualcomm Snapdragon 8cx (Expected) |
| Apps | 8:27 - 10:21 | 16:11 - 17:01 |
| Video | 10:19 - 12:17 | 17:27 - 19:55 |
| Idle | 15:02 - 15:45 | 22:00 - 23:27 |
From these numbers, it seems that Snapdragon 8cx will rival a Core i5, which is very interesting because it adds a new competitor in the market of notebooks for Intel and AMD, in addition to improving the segment of ARM notebooks 'Always Connected' of great autonomy.
