# Intel Celeron 3765U Laptop CPU: Intel Also called intel celeron 3765u, celeron 3765u, 3765u, celeron-3765u Intel, Laptop CPU, Broadwell Intel Celeron laptop processor on Broadwell, with 2 cores and 2 threads and 2 MB L3 at 15 W TDP on a 14 nm process addressing up to 16 GB and Intel HD Graphics for 5th Generation Intel Processors. ## What you need to know Intel Celeron 3765U is a legacy laptop cpu. Intel Celeron 3765U launched in April 1, 2015., It has 2 cores and 2 threads on Broadwell, dropping into the FCBGA1168 socket. Treat the spec table as the facts. Age alone does not tell you to throw it out. - **Still good?**: Only if the workload is light **Product age**: 11 years old **Upgrade pressure**: Moderate Feex says Laptop SKUs are power-limited. The name on the lid is not the same chip you would get on a desktop board. ## What this hardware means today Age and usefulness are not the same number. This page keeps them separate. - **Performance today**: **Modest.** Laptop performance depends on the OEM power limit as much as this SKU name. **Product age 11 years old**: **Legacy.** Launched April 1, 2015. Newer platforms exist. That does not make this chip unusable by itself. **Support status **: **Supported.** Current Windows and current applications still run on this class of CPU. Platform BIOS support depends on the motherboard or laptop vendor. **Upgrade pressure **: **Moderate.** Upgrade pressure comes from platform features and specific CPU-bound work, not from the chip being unusable. ## Where does it sit? Broadwell sits on Intel's recent Core timeline. Later desktop branding moved toward Core Ultra. 11th Gen 12th Gen 13th Gen 14th Gen Core Ultra ## Performance context These are qualitative readings, not a fake 8.7 out of 10. Workload still wins. ### Gaming: Good Fine when the laptop GPU is the limit. CPU names on thin laptops often are not. ### Productivity: Modest 2 cores cover office, browser, and compile work in this class. ### Multithreaded workloads: Average 2 threads. Heavy encodes still scale further on higher-core parts. ### General use: Good Everyday Windows use is not where most people notice this SKU first. ### Efficiency: Depends on the laptop The same SKU in two laptops can draw very different power. Read the device, not the CPU name alone. ## Should you upgrade? Probably not based on CPU performance alone. ### Upgrade makes more sense if - Your workload is strongly CPU limited - You need a newer platform for memory, I/O, or chipset features - You need substantially more multicore performance - You are buying a whole new laptop anyway ### Upgrade makes less sense if - The GPU is the real bottleneck - Current applications are already responsive - The CPU rarely limits your workload ## Specifications Figures below follow the Feex Hardware Database record for this SKU. Fields without a recorded value are omitted. ### Processor Intel Celeron 3765U is built on Broadwell using a 14 nm process. | Manufacturer | Intel | | --------------------- | ----------------------------------- | | Family | Celeron | | Architecture | Broadwell | | Generation | Intel Celeron Processor 3000 Series | | Manufacturing process | 14 nm | | Segment | Laptop | ### Cores and threads Intel Celeron 3765U has 2 cores and 2 threads. | Cores | 2 | | ------- | - | | Threads | 2 | ### Clock speeds Base clock is 1.9 GHz. | Base frequency | 1.9 GHz | | -------------- | ------- | ### Cache Cache on this sheet is 2 MB L3. | L3 cache | 2 MB | | ----------- | ---- | | Total cache | 2 MB | ### Memory Intel Celeron 3765U addresses 16 GB across 2 memory channels. | Supported types | LPDDR3 | | --------------- | ------ | | Max capacity | 16 GB | | Channels | 2 | ### Package and power Intel Celeron 3765U uses the FCBGA1168 socket and a 15 W TDP. | Socket | FCBGA1168 | | ------ | ---------------------- | | TDP | 15 W | | PCIe | Revision 2.0, 12 lanes | ### Integrated graphics Intel Celeron 3765U includes Intel HD Graphics for 5th Generation Intel Processors. | Integrated graphics | Intel HD Graphics for 5th Generation Intel Processors | | ------------------- | ----------------------------------------------------- | ### Market Intel Celeron 3765U launched April 1, 2015. | Launch date | April 1, 2015 | | ----------- | ------------- | | Model | 3765U | ### Features Intel Celeron 3765U records 3 instruction sets on this sheet. | Instruction sets | 64-bit (x86-64)SSE4.1SSE4.2 | | ---------------- | ---------------------------------------------------------------------------- | | Security | Hardware RNG | | Virtualization | Extended Page Tables (EPT)VT-d (DMA Remapping)VT-x (Hardware Virtualization) | ## Compatibility | Socket | FCBGA1168 | | -------- | ------------------------------------------------------------------------------------------------- | | Board | A shared socket is not automatic compatibility. Check the motherboard CPU list and BIOS revision. | | Memory | LPDDR3, up to 16 GB | | Graphics | Intel HD Graphics for 5th Generation Intel Processors | A shared socket is not automatic compatibility. Boards often need a BIOS update before a newer chip in the same socket will post. Laptop power limits, cooling, and the OEM firmware matter as much as the model name. Read the memory list on the board. The CPU can list more standards than one motherboard will accept. ### No post after a CPU swap Clear CMOS only after you confirm the board list includes this SKU and the BIOS is new enough. A supported name on a box is not the same as a flashed board. ## Related These entities connect to this article. Type is shown on every link.
