CPU Comparison
Intel Core 3 305 vs Intel Core 5 330
A side-by-side comparison of specs, performance and value. Intel Core 3 305 is a six-core mobile SoC from the Wildcat Lake family, pairing two Cougar Cove P-cores with four Darkmont low-power efficient cores and a single Xe3 iGPU, designed primarily for affordable laptops and edge devices.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Everyday office work, web apps, and light multitasking feel responsive thanks to the 4.3 GHz P-core and modern IPC. Single-channel memory can affect memory-sensitive workloads, but the 4 MB memory-side cache helps mitigate latency.
Snappy single‑thread performance from the Cougar Cove P‑cores makes everyday tasks, office suites, and web apps feel responsive, though sustained multi‑thread workloads are limited by 6‑core/6‑thread configuration and single‑channel memory.
Gaming
Not aimed at gaming. The single Xe3 core (16 EUs) can handle very light and older titles at low settings, but modern AAA games will be severely limited by both GPU throughput and single-channel memory bandwidth.
With two Xe3 cores and single‑channel memory, the Core 5 330 can handle older or lighter games and eSports titles at low/medium settings, but it is not intended as a gaming chip.
Virtualization
Limited by 6 GB total addressable RAM on many value laptops and only 6 PCIe lanes; adequate for light VMs but not for serious lab work.
Supports VT‑x, VT‑d, and EPT, so it can run a few VMs for light lab work, but with only 6 cores and modest memory bandwidth it is better suited to one or two light VMs than heavy server workloads.
Efficiency
The 18A process, low base power, and LP-E cluster allow thin-and-light devices with long battery life, especially at 10–15 W. OEMs targeting fanless designs can push minimum assured power down to 10 W per ARK.
The 15 W base power and Intel 18A process contribute to strong efficiency for everyday workloads, aligning with Intel’s all‑day battery claims for the Wildcat Lake platform.
Specialized Performance
AI / ML
- Platform-level AI TOPS vary by SKU (family up to ~40 TOPS with GPU+NPU+CPU). For Core 3 305, ARK does not list NPU TOPS; the GPU alone contributes 9 TOPS (Int8), and CPU DLBoost adds some CPU TOPS for supported instructions.
- Suitable for running small models and inference tasks via OpenVINO, DirectML, or WebNN, and for UI AI enhancements (background blur, eye gaze).
- Not targeted for large local LLMs or sustained AI training workloads.
- NPU delivers 16 INT8 TOPS with sparsity support, suited to local inference tasks.
- GPU contributes an additional 20 INT8 TOPS; CPU also supports DL Boost.
- Software support includes OpenVINO, WindowsML, DirectML, ONNX RT, and WebNN.
- Meets everyday AI features (e.g., Windows Studio Effects) but falls short of Microsoft’s 40 TOPS NPU‑only Copilot+ PC requirement.
Content Creation
Gaming
- Single Xe3 core (16 EUs) with 2.3 GHz max clock provides only light gaming capability.
- Single-channel memory reduces available bandwidth for GPU workloads.
- Suitable for older or very light e-sports at low resolutions and settings; not designed for modern AAA gaming.
- Integrated Intel Graphics with 2 Xe3 cores and up to 2.5 GHz boost.
- Single‑channel memory limits GPU bandwidth.
- Best suited for eSports and older titles at 1080p low/medium.
- AV1 encode/decode helps with streaming from supported apps.

Strengths & Weaknesses
Pros
- Modern 18A compute and GPU in a small, 35×25 mm FCBGA1516 package.
- Hybrid 2P+4LP-E design delivers responsive single-thread performance and good efficiency.
- Single-channel DDR5/LPDDR5X with 4 MB memory-side cache helps everyday memory latency.
- Up-to-date I/O: six PCIe 4.0 lanes, Thunderbolt 4, Wi-Fi 7 (R2), Bluetooth 6.0.
- Low power envelope (10–35 W) enables fanless or ultra-portable designs.
Cons
- No Hyper-Threading (6 cores/6 threads) limits heavily threaded workloads.
- Single-channel memory caps bandwidth; memory-sensitive workloads suffer despite the 4 MB MSC.
- Only one Xe3 core (16 EUs) for graphics—insufficient for serious 3D gaming.
- Only six PCIe 4.0 lanes constrain storage and expansion options.
- NPU TOPS are lower than higher-tier Core Ultra 3 parts; Core 3 305 is not designed as a Copilot+ PC.
Pros
- Modern Intel 18A compute tile with Cougar Cove and Darkmont LP‑E cores.
- 16 TOPS NPU plus 20 TOPS GPU AI (40 TOPS platform total including CPU).
- Single‑channel LPDDR5X‑7467 / DDR5‑6400 with a 4 MB memory‑side cache.
- Very low 15 W base power with 35 W turbo for occasional bursts.
- Thunderbolt 4 and six PCIe 4.0 lanes for a value platform.
- SIPP and TXT support for commercial and fleet deployments.
- AV1 encode/decode and Quick Sync Video for modern codecs.
Cons
- Only six PCIe 4.0 lanes and single‑channel memory, limiting high‑end use cases.
- No Hyper‑Threading on LP‑E cores, so threads equal cores (6/6).
- Not intended for serious gaming or heavy content creation workloads.
- Multiplier is locked; no enthusiast overclocking.
