Intel Core i7-12800H debut: Razer Blade 15 laptop review

Razer has refreshed its Blade 15 series this year to include the latest Intel CPUs and Nvidia GPUs. In this case, the model is getting 12th gen Alder Lake-H Core i7-12800H and Core i9-12900H CPUs alongside the GeForce RTX 3070 Ti and 3080 Ti (110 W TGP) to replace the older 11th gen Core i7-11800H, Core i9-11900H, RTX 3070, and RTX 3080 (105 W TGP) options. This review will focus on the performance differences users can expect when upgrading from an older Razer Blade 15 to the latest 2022 configuration in review.
Alternatives to the Blade 15 include other ultrathin 15.6-inch gaming laptops like the Eurocom RX315, MSI GS66, ADATA XPG Xenia 15, or the Asus Zephyrus S series.

Case
The chassis remains mostly identical to last year's Advanced Model and so there are no changes to the dimensions or feel of the system. If you've handled a Blade Stealth, Blade 14, Blade 15, or Blade Pro 17 in the past, then this latest 2022 will feel familiar.
The only major physical change this year is to the keyboard keycaps which are now slightly larger than before. The Power button has also been relocated which doubles as an easy way to visually distinguish between the 2022 model from earlier models.

Maintenance
Accessories and Warranty
There are no extras in the box other than the AC adapter and paperwork.
A base one-year warranty plus two-year battery warranty are included with every new purchase of a 12th gen Blade model. Note, however, that the two-year battery warranty does not currently apply to older Blade models.
Input Devices
Though the large clickpad remains the same, Razer has upgraded the keyboard on the 2022 Blade 15 with slightly larger keycaps than on previous generation models to reduce typing errors. Consequently, the space between each key has been reduced. Travel and feedback are otherwise identical year-over-year.
Display
The Blade 15 is one of the few 15.6-inch laptops to come with a 240 Hz 1440p panel that covers the entire DCI-P3 standard. The 165 Hz 1440p panel on the Xenia 15, for example, covers all of sRGB but only 68 percent of P3. Black-white and gray-gray response times are also very good meaning that this panel can be used for both gaming and digital editing. In previous years, Blade 15 owners would have had to settle for 4K UHD options instead for the full DCI-P3 coverage.

The display is well-calibrated out of the box with average grayscale and color DeltaE values of just 1.1 and 2.74, respectively, against the DCI-P3 standard. Razer says it individually calibrates each panel at factory and our independent measurements with an X-Rite colorimeter can confirm the accurate colors and grayscale.

Performance
Testing Conditions
Our unit was set to Custom performance mode with CPU to Boost and GPU to High via the Razer Synapse software prior to running any performance benchmarks below for the highest possible scores. We also enabled the dGPU by disabling Optimus. It's highly recommended to become familiar with Razer Synapse as it is the software hub for controlling performance and features.
Users can switch between dGPU only or Nvidia Optimus (MUX) without needing to restart the system since the Blade 15 is one of the few gaming laptops to support Advanced Optimus or Optimus 2.0. Keep in mind that G-Sync for the internal display will only work when not in Optimus mode. Additionally, Thunderbolt 4 support will only be enabled when on Optimus mode much like on other laptops running on 12th gen Alder Lake-H CPUs.
Processor
The Core i7-12800H offers 20 percent faster single-thread and multi-thread performance over the last generation Core i7-11800H that it directly replaces. Upgrading to the Core i9-12900H SKU is expected to boost CPU performance by another 5 to 15 percent based on our experience with the MSI Vector GP66.

Storage Devices
Nearly all Razer Blade laptops use either Lite-On or Samsung SSDs and the latest Blade 15 is no exception. Our test unit comes equipped with the 1 TB Lite-On CA6-8D1024 PCIe4 x4 NVMe SSD for sequential read and write rates of up to 6800 MB/s and 4800 MB/s, respectively. Our DiskSpd Read Loop test shows that the drive has no issues maintaining its maximum performance levels for extended periods.

GPU Performance
Graphics performance is about 15 to 25 percent higher than the Blade 15 RTX 3080 or 30 to 45 percent faster than the Blade 15 RTX 2080 Max-Q. Certain alternatives like the Schenker XMG Neo 15 E22 or Schenker Uniwill Technology GM7AG8P come with higher-power 150+ W versions of the same GeForce RTX 3080 Ti GPU for a 10 to 15 percent performance boost over our Blade 15 RTX 3080 Ti.
