Which display is better for daily use?
Google Pixel 8 has a 6.2-inch Actua OLED display with 60–120Hz refresh, while Pixel 8a has a 6.1-inch Actua OLED display reaching 120Hz.
The display specifications below show the differences in size, brightness, protection and refresh rate for scrolling, video and outdoor viewing.
| Specification | Google Pixel 8 | Google Pixel 8a |
|---|
| Display size | 6.2-inch | 6.1-inch |
| Display type | Actua OLED | Actua OLED |
| Resolution | 1080 x 2400 pixel | 1080 x 2400 pixel |
| Refresh rate | 60–120Hz | Up to 120Hz |
| Touch sampling rate | Not specified | Not specified |
| Peak brightness | Up to 2,000 nits | Up to 2,000 nits |
| Display protection | Corning Gorilla Glass Victus | Corning Gorilla Glass 3 |
| HDR | Supported | Supported |
| Fingerprint sensor | Under-display fingerprint sensor | Under-display fingerprint sensor |
| Water and dust resistance | IP68 | IP67 |
Pro tip: If you regularly use your phone outdoors or want stronger protection against water and dust, Pixel 8's IP68 rating and Gorilla Glass Victus are useful differences.
Which phone has stronger performance and software support?
Both phones use the Google Tensor G3 processor and 8GB LPDDR5X RAM, so the core processing hardware is the same.
The performance setup gives both phones enough memory for switching between common apps, while seven years of updates support longer ownership.
| Specification | Google Pixel 8 | Google Pixel 8a |
|---|
| Processor | Google Tensor G3 | Google Tensor G3 |
| Processor core | Nine-core | Nine-core |
| GPU | Immortalis-G715s MC10 | Immortalis-G715s MC10 |
| Manufacturing process | 4 nm | 4 nm |
| RAM | 8GB | 8GB |
| RAM type | LPDDR5X | LPDDR5X |
| Operating system | Android 14 at launch | Android 14 at launch |
| User interface | Pixel UI | Pixel UI |
| Storage type | UFS 3.1 | UFS 3.1 |
Keep in mind: The shared processor means Pixel 8a does not give up the Tensor G3 platform simply because it is the lower-priced model. Pixel 8's extra cost is tied more to its display, build and camera hardware.
Which phone offers the better camera setup?
Google Pixel 8 uses a 50MP main camera and 12MP ultrawide camera, while Pixel 8a uses 64MP and 13MP rear cameras with Google's image processing.
The camera specifications show why megapixel count alone does not tell the whole story, especially when the two phones use different sensors and camera systems.
| Specification | Google Pixel 8 | Google Pixel 8a |
|---|
| Rear camera setup | 50MP wide + 12MP ultrawide | 64MP wide + 13MP ultrawide |
| Main camera | 50MP, f/1.68, OIS | 64MP, f/1.89, OIS |
| Ultra-wide camera | 12MP, 126° field of view | 13MP, 120° field of view |
| Macro camera | Not specified | Not specified |
| Front camera | 10.5MP | 13MP |
| Rear video recording | Up to 4K | Up to 4K |
| Front video recording | Up to 4K | Up to 4K |
Pro tip: Do not choose between the two only by comparing 64MP and 50MP. Sensor size, stabilisation, processing and the type of shots you take matter more for daily photography.
How do storage and connectivity compare?
Both phones offer 128GB and 256GB storage with no memory card slot, while Pixel 8 and Pixel 8a support 5G, Wi-Fi and Bluetooth connectivity.
The connectivity setup covers common wireless features, wired connections and storage expansion for people who use phones across work, travel and entertainment.
| Specification | Google Pixel 8 | Google Pixel 8a |
|---|
| Storage options | 128GB / 256GB | 128GB / 256GB |
| Expandable storage | No | No |
| Wi-Fi | Wi-Fi 7 | Wi-Fi 6E |
| Bluetooth | Bluetooth 5.3 | Bluetooth 5.3 |
| GPS | Supported | Supported |
| NFC | Supported | Supported |
| USB | USB Type-C | USB Type-C |
| 3.5mm headphone jack | No | No |
| IR blaster | Not specified | Not specified |
Keep in mind: Neither phone accepts a memory card, so 128GB can become limiting if you store many large videos. The 256GB option is more useful for longer-term storage.
Which phone has better battery and charging features?
Google Pixel 8 has a 4,575 mAh battery with up to 27 W wired charging, faster wireless charging and Battery Share, while Pixel 8a has a 4,492 mAh battery.
The charging difference matters more if you use wireless charging or want to share battery power with compatible accessories.
| Specification | Google Pixel 8 | Google Pixel 8a |
|---|
| Battery capacity | 4,575 mAh | 4,492 mAh |
| Wired charging | Up to 27 W | Fast charging |
| Wireless charging | Up to 18 W with Pixel Stand 2 | Up to 7.5 W with Pixel Stand |
| Reverse charging | Battery Share supported | Not supported |
| Stereo speakers | Supported | Supported |
| Dolby Atmos | Not specified | Not specified |
| Security | Titan M2 security chip | Titan M2 security chip |
| Water and dust protection | IP68 | IP67 |
Keep in mind: Pixel 8 has the larger battery, faster wireless charging and Battery Share, but neither phone is designed around very high-wattage wired charging.
