Processor
Boost Clock Speed
Boost clock speed (GHz) is the peak frequency a few cores can reach for short bursts when thermal and power headroom allow. Higher boost clock makes interactive apps feel snappier and accelerates short, bursty workloads like web browsing and Office.
5.2 GHz
Processor Model
Intel Core 7 240H
CPU Brand
Intel
Efficiency Cores
Efficiency cores (E-cores) are smaller, lower-power CPU cores that handle background tasks (telemetry, sync, web tabs) while the P-cores stay free for the active app. They boost multi-threaded throughput cheaply and extend battery life on notebooks.

Performance Cores
Performance cores (P-cores) are the high-power CPU cores used for demanding foreground tasks - games, rendering, single-threaded productivity. They run at the highest clock speeds and consume the most power. P-core count is the main driver of peak single-

Memory Speed
Memory speed (MT/s or MHz) is how many transfers per second the RAM can do. Higher memory speed reduces the wait for data and noticeably boosts performance on Ryzen CPUs and integrated graphics. DDR5-5600 is the current entry; DDR5-6400+ benefits enthusia
5600 MHz
Cache Memory
Cache memory is the tiny but extremely fast on-chip memory the CPU uses to keep frequently accessed data close to the cores. Larger L2 and L3 caches cut down on slow trips to system RAM, which is especially valuable for gaming, databases and compilation.

Memory Type
Memory type sets the RAM generation. DDR5 is the current standard for Intel 12th-gen+ and AMD AM5; it delivers higher bandwidth and lower voltage than DDR4. DDR4 is still common on older platforms. Memory type must match the motherboard; the slots are phy

Memory Slots
Number of physical RAM slots (DIMM or SO-DIMM) available on the motherboard.

NVMe
NVMe SSDs are 5–10× faster than SATA. Standard in modern notebooks.

SSD Storage
SSD storage (GB or TB) is the usable space on the solid-state drive. The operating system plus a few games and apps already consumes 200-400 GB. 1 TB is comfortable for general use, 2 TB+ for large game libraries or content creation.

Display
Resolution
Native resolution is the pixel grid the panel was designed to display. FHD = 1920x1080, QHD = 2560x1440, 4K UHD = 3840x2160, 5K = 5120x2880. Running below native resolution makes the image fuzzy unless content is scaled cleanly (which only works for some
1920 x 1200 pixels
Refresh Rate
Refresh rate (Hz) is how many times per second the screen redraws its image. 60 Hz is the standard for productivity; 120-144 Hz feels noticeably smoother for everyday use; 240+ Hz benefits competitive gaming. Higher refresh rate also reduces motion blur.
165 Hz
Resolution Class
FHD=1920×1080, QHD=2560×1440, 4K=3840×2160, OLED refers to panel type.

Connectivity
Bluetooth Version
Bluetooth version controls range, throughput and the supported audio codecs. 5.0+ doubles range and bandwidth vs 4.x; 5.3 adds LE Audio with the higher-quality LC3 codec. Both endpoints must speak the same version to use the new features.

Wi-Fi
Wi-Fi generation sets peak speed and how well the device coexists with neighbours. Wi-Fi 6 (802.11ax) is the modern baseline; Wi-Fi 6E adds the cleaner 6 GHz band; Wi-Fi 7 (Be) brings multi-link operation and even higher peaks. The router and the client m

HDMI Version
HDMI version determines the maximum supported resolution and refresh rate. HDMI 2.0 = 4K at 60 Hz, HDMI 2.1 = 4K at 120 Hz or 8K at 60 Hz with HDR. To run 4K120 the HDMI cable, source and display must all be 2.1.

Battery Capacity
Battery capacity (Wh or mAh) is the total energy the battery stores. For comparing devices the Wh value is the meaningful one (mAh requires knowing the voltage too). Bigger capacity adds weight and bulk; mid-range notebooks land at 50-70 Wh.
