Intel Core 3 304 socket: BGA 1516

What the Core 3 304 is

The Intel Core 3 304 is a 5-core, 5-thread mobile processor that Intel launched in April 2026 as the entry point of Core Series 3, the family codenamed Wildcat Lake. It is the only SKU in the family with a single Cougar Cove Performance-core, running at 1.5 GHz and reaching up to 4.3 GHz, beside four Darkmont low-power Efficient-cores at 1.4 GHz and up to 3.3 GHz. The five cores share the same 6 MB of Intel Smart Cache as the rest of the family, and one thread per core gives five threads.

Graphics use a single Xe3 core at up to 2.3 GHz with 9 TOPS of Int8 throughput, which covers office work, video calls and media playback while sipping power. A discrete NPU with 15 TOPS handles background camera effects and entry level on-device AI. Intel builds the compute tile on the Intel 18A process, and power ratings match the family at 15 W of processor base power, up to 35 W of maximum turbo power, and 10 W minimum assured power.

The single Performance-core defines the 304. Single-threaded bursts still reach 4.3 GHz, so everyday responsiveness stays close to its Core 3 305 sibling, but only one core can hold that peak while the four low-power Efficient-cores absorb the rest. Notebookcheck describes exactly this split: one fast Cougar Cove core plus four Darkmont low-power cores. Multithreaded throughput therefore trails every 6-core SKU in the family, while idle and light-load efficiency lead it.

Intel aims the 304 at the cheapest laptops and small systems where die cost and cooling budget dominate. TechPowerUp lists it as an active mobile part from April 2026, and press coverage names compact PCs built around Wildcat Lake silicon in this class. Buyers get modern media blocks, AV1 decode and an NPU at the lowest price in the Core brand, and they trade peak multithreaded speed for it.

Socket and motherboard compatibility

The Core 3 304 is soldered to its board in the BGA 1516 ball grid array, so there is no socket to plug into and the chip cannot be replaced or upgraded later. The 1,516-ball joint is made once at the factory on a 35 × 25 mm FCBGA1516 package, and each laptop or compact board is qualified around this exact SKU for its whole service life.

There is no board or chipset choice in the retail sense. The system vendor fixes the memory type and capacity, sets the power policy inside the 10 W to 35 W span, and validates the thermal design for that envelope. Firmware and driver support come from the same vendor, so shoppers compare finished systems rather than motherboards.

The BGA 1516 footprint carries all seven Wildcat Lake SKUs, from this 5-core part up to the Core 7 360. A shared package does not create an upgrade path, because each SKU needs its own board build and firmware. Choosing between the 304 and the 6-core 305 happens at purchase, not on a workbench.

Memory, PCIe and cooling

Memory is single-channel by design. The controller supports LPDDR5X up to 7467 MT/s or DDR5 up to 6400 MT/s, with up to 64 GB depending on memory type, and the fitted type and size are fixed when the board is built. Entry laptops usually pair this SKU with soldered LPDDR5X, which trims idle power and board space at the cost of any later capacity change. The single channel feeds the CPU, the single Xe3 graphics core and the NPU from one pool.

Expansion comes from six PCIe 4.0 lanes out of the processor. Those lanes typically serve NVMe storage and basic peripherals, while the integrated graphics drive the panel and external displays. The exact lane split and port list are set per system design, so the vendor specification governs.

Cooling is a system responsibility inside the 10 W to 35 W ratings, and the 304 is the easiest Wildcat Lake SKU to cool. One Performance-core and a single Xe3 graphics core keep peak draw low, which suits slim fanless or single-fan shells. There is no boxed cooler and no retail heatsink list for a soldered mobile processor.

Upgrade paths

There is no CPU upgrade path on a soldered package. When five threads stop being enough, the natural in-family step is a system built around the 6-core Core 3 305 or Core 5 315, which add a second Performance-core and higher peaks on the same socket. Memory size changes mean a new board for the same reason.

Moving off BGA 1516 means a new platform. Buyers who outgrow the entry tier entirely look at higher core count mobile designs or socketed desktops. The LGA, PGA and BGA: CPU package types explained guide explains how soldered packages differ from socketed ones and why the whole device is the unit of replacement here.
