The Intel Core i5-5300U is a dual-core Broadwell-U mobile processor with Intel HD 5500 graphics, offering slightly higher clocks than the i5-5200U for mainstream ultrabooks requiring balanced 15W performance.
The Intel Core i5-5300U features 2 cores and 4 threads with a base clock of 2.3 GHz and turbo up to 2.9 GHz — a modest 100 MHz base and 200 MHz turbo improvement over the i5-5200U.
It uses the smaller 82mm² die with 1.3 billion transistors and Intel HD 5500 graphics with 24 Execution Units at 300-900 MHz. The 15W TDP with configurable TDP down to 7.
5W matches the i5-5200U, and it supports DDR3-1600 memory on dual channels. This processor was aimed at mainstream business and consumer ultrabooks where the slight clock advantage over the i5-5200U could justify a small price premium in OEM configurations.

Architecture Overview
The i5-5300U uses the smaller 82mm² GT2 die that Intel designed for cost-effective Broadwell-U implementations. This die contains only the CPU cores and a GT2-class integrated GPU (HD 5500) with 24 Execution Units, without the 128MB eDRAM found on the larger GT3 die. The 2.3 GHz base and 2.9 GHz turbo clocks represent a modest binning improvement over the i5-5200U's 2.2 GHz base and 2.7 GHz turbo. The architecture is fundamentally identical — same Broadwell microarchitecture, same cache hierarchy, same memory controller. The small clock increase comes from slightly better silicon quality in the binning process, where dies capable of stable operation at higher frequencies within the 15W TDP are assigned to the i5-5300U SKU. The DDR3-1600 memory controller and 12 PCIe Gen 2 lanes are unchanged from the i5-5200U.
CPU Design
Two Broadwell cores with Hyper-Threading, 64KB L1 and 256KB L2 per core, 3MB shared L3 Smart Cache — identical layout to the i5-5200U with higher clock targets.
Memory Subsystem
Dual-channel DDR3-1600 controller providing 25.6 GB/s bandwidth, same as the i5-5200U.
PCIe & I/O
12 PCIe Gen 2 lanes from the CPU, standard for all Broadwell-U variants.

History
The Core i5-5300U served as Intel's mainstream workhorse for business ultrabooks in the Broadwell generation. While the i5-5200U launched as the entry-level i5 option, the i5-5300U provided OEMs with a slightly higher-clocked alternative for mid-tier laptop configurations, particularly in the enterprise segment where vPro manageability was valued.</br></br>In practice, the i5-5300U was a product of Intel's meticulous binning strategy.
The 82mm² die was shared with the i5-5200U, with the i5-5300U receiving dies that could sustain stable operation at 2.3 GHz base and 2.9 GHz turbo within the 15W power budget.
For enterprise IT departments, the i5-5300U represented a safe, standardized choice for fleet deployments — reliable, efficient, and compatible with Intel's vPro management platform.</br></br>The processor's legacy is one of quiet ubiquity rather than excitement. It powered countless Dell Latitudes, HP ProBooks, and Lenovo ThinkPads in offices worldwide throughout 2015-2018.
While it never garnered attention from enthusiasts, it reliably executed the tasks it was designed for. However, its dual-core architecture became a liability as web applications grew more demanding, and many organizations found themselves replacing i5-5300U laptops earlier than anticipated as browser-based workflows pushed the chip beyond its comfortable operating range.
Improvements over Previous Generation
- 14nm process from 22nm
