CPU Comparison
Intel Core 3 304 vs Intel Core 5 315
A side-by-side comparison of specs, performance and value. Intel Core 3 304 is a five-core mobile processor from the Wildcat Lake (Core Series 3) family, built on Intel 18A, with one Cougar Cove P-core and four Darkmont low-power E-cores. It delivers up to 4.3 GHz P-core boost, 15 W base / 35 W turbo power, an NPU 5 block rated at 15 TOPS (INT8), and a single Xe3 graphics core at 2.3 GHz capable of 9 TOPS. It targets affordable thin-and-light laptops, mini PCs, and edge AI devices with single-channel LPDDR5X up to 7467 MT/s or DDR5 up to 6400 MT/s, six PCIe 4.0 lanes, Thunderbolt 4, and a 4 MB memory-side cache to reduce memory latency.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Everyday productivity is snappy thanks to strong single‑thread performance from the Cougar Cove core and efficient task scheduling across LPE cores.
Handles standard office suites flawlessly, but the 6-thread limit causes slowdowns in heavy spreadsheet calculations or large file processing.
Gaming
With only one Xe3 core and single‑channel memory, gaming is limited to light or older titles; it is not aimed at mainstream or high‑refresh‑rate gaming.
While Xe3 graphics are powerful, the single-channel memory bottleneck severely limits frame rates in modern 3D games.
Virtualization
Fine for a single light VM or container, but limited threads and memory channels restrict more serious virtualization use cases.
Can run light VMs for development or testing, but limited core count and memory bandwidth constrain heavier workloads.
Efficiency
The 15 W base and 10 W minimum assured power, combined with Intel 18A and the 4 MB memory‑side cache, enable long battery life in thin‑and‑light designs.
The 3nm compute tile and lack of SMT result in class-leading performance-per-watt for everyday tasks.
Specialized Performance
AI / ML
- NPU 5 provides 15 TOPS for on‑device AI, supporting Windows Studio Effects and lightweight local inference.

- Meets the 40+ TOPS requirement when including CPU and GPU contributions
- NPU 5 is highly efficient for sustained AI tasks
- Excellent for local Copilot+ PC features
Content Creation
Gaming
- Single Xe3 graphics core constrains GPU throughput.
- Single‑channel memory bandwidth limits heavy 3D workloads.
- Suitable for light e‑sports or older titles at low settings; not intended for AAA gaming.
- Single-channel memory heavily restricts iGPU bandwidth
- Xe3 architecture shows promise for esports titles at low settings
- Not intended as a gaming processor
