Qualcomm's Snapdragon 888 often outperforms the Exynos 2100 in GPU benchmarks. Exynos is Samsung's own chipset brand, and Snapdragon is developed by Qualcomm.
Which RAM technology is commonly used in modern flagship smartphones for improved power efficiency?
HBM2
GDDR6
DDR3
LPDDR4X
LPDDR4X is a low-power DDR memory standard widely used in flagship smartphones for its balance of speed and energy efficiency. DDR3 is older and less efficient, GDDR6 and HBM2 are used in graphics and high-performance computing.
In smartphone cameras, what does the term aperture describe?
Shutter speed
Lens opening size
Pixel count
Sensor size
Aperture refers to the size of the lens opening that lets light reach the camera sensor. A wider aperture (lower f-number) allows more light and affects depth of field.
Which connectivity standard is used for wireless local area network connections?
NFC
Bluetooth
Zigbee
Wi-Fi
Wi-Fi enables high-speed wireless local area network connections over tens or hundreds of meters. NFC is for very short ranges, Bluetooth is for personal area networks, and Zigbee is for low-power IoT.
For a user prioritizing long battery life, which smartphone spec is most relevant?
High refresh rate screen
Large mAh battery
Largest camera sensor
Highest GPU score
Battery capacity in mAh is the most direct indicator of potential runtime, assuming similar power consumption. A high refresh rate screen and powerful GPU often consume more power, reducing battery life.
Which technology allows a smartphone to have multiple SIM profiles without a physical SIM card?
Dual SIM tray
eSIM
Micro-SIM
Nano-SIM
An eSIM is an embedded SIM that can store multiple operator profiles digitally. It eliminates the need for physical SIM cards and supports remote provisioning.
In LTE-Advanced, which feature combines multiple frequency bands to increase data throughput?
Carrier aggregation
Beamforming
VoLTE
MIMO
Carrier aggregation in LTE-Advanced combines separate frequency bands into a single, wider data pipe, boosting throughput. MIMO increases capacity through multiple antennas, beamforming focuses signals, and VoLTE is voice over LTE.
Compared to LPDDR4X, what benefit does LPDDR5 RAM provide in smartphones?
Higher clock speed and bandwidth
Lower camera resolution
Smaller screen size
Lower refresh rate
LPDDR5 offers higher clock speeds and greater data bandwidth while improving power efficiency over LPDDR4X. This boosts performance for demanding tasks like gaming and multitasking.
A smartphone advertising "sub-6 GHz" 5G refers to which frequency range?
Ultra-high band
Above 6 GHz
Satellite band
Below 6 GHz
Sub-6 GHz 5G uses frequencies below 6 GHz, offering a balance of coverage and speed. Frequencies above 6 GHz (mmWave) provide higher speeds but shorter range.
Why might a smartphone with an integrated 5G modem consume less power than one using a separate modem chip?
Separate chips eliminate software updates
Integrated modems reduce inter-chip communication overhead
Separate modems always overclock the CPU
Integrated chips require additional cooling
An integrated 5G modem shares power and data paths with the main SoC, reducing inter-chip communication overhead and power loss. Separate modem chips require additional interfaces and can be less efficient.
