What the Celeron 797 is
Intel Celeron 797 is a single core Sandy Bridge mobile processor that Intel released in January 2012 for thin laptops with soldered boards. It runs at a fixed 1.4 GHz with no turbo and no Hyper-Threading, so 1 core gives 1 thread. Cache is 1.5 MB Intel Smart Cache. Power is rated at 17 W on a 32 nm process.
Graphics are Intel HD Graphics for Sandy Bridge at 350 MHz to 950 MHz. The low base suits thin bodies with small batteries. The controller takes DDR3 SODIMMs at 1066 or 1333 MT/s, often soldered in the thinnest designs.
One thread at low clocks covers single task web and office loads of the period and little more. Laptops pair it with HM65 class boards and small drives. The LGA, PGA and BGA: CPU package types explained guide explains why this soldered BGA part cannot be serviced like Socket G2 Celerons.
Socket and motherboard compatibility
The Celeron 797 solders to BGA 1023 with 1,023 balls in a 31 by 24 mm footprint and cannot be moved. Thin makers qualify each model with a fixed board and BIOS, so another BGA part is not a field swap. Boards use slim layouts with soldered or slotted RAM.
The BIOS must list the exact Celeron 797 string. Power is light, so screen and battery decide the buy. The CPU cooler compatibility by socket guide notes soldered mobile cooling stays board specific.
Memory, PCIe and cooling
Memory support is DDR3-1066 and 1333, two channels, up to 16 GB. The thinnest bodies solder RAM and lock size at purchase. Two channels still help the shared graphics block.
PCI Express lanes come from the CPU in a board specific layout for Wi-Fi and storage. There is no graphics slot to consider at 17 W.
Cooling is a slim 17 W spreader and fan. Fixed 1.4 GHz operation needs little airflow, but dust still raises fan noise over time.
Upgrade paths
There is no CPU upgrade path on soldered BGA 1023. The Celeron 797 cannot be removed, so a faster thin laptop means a new board or a new device. A soldered dual comparison is Intel Celeron 867 on the same package, but boards rarely exchange models.
A platform move means a new thin laptop on a current BGA package. Keep the old machine for single task duty after wiping the drive.
Frequently asked questions
What socket does the Intel Celeron 797 use?
It uses BGA 1023, a soldered package. The chip cannot be removed.
How many threads does the Celeron 797 have?
One core with 1 thread at a fixed 1.4 GHz.
What memory does the Celeron 797 use?
DDR3-1066 and 1333, two channels, up to 16 GB.
Can the Celeron 797 be upgraded?
No. Soldered BGA parts need a board or laptop replacement for more speed.
