The Intel Core i5-5300U is an ULV (ultra low voltage) dual-core processor based on the Broadwell architecture, which has been launched in January 2015. In addition to two CPU cores with Hyper-Threading clocked at 2.3 - 2.9 GHz (2 Cores: 2.7 GHz), the chip also integrates an HD Graphics 5500 GPU and a dual-channel DDR3(L)-1600 memory controller. The Core i5 is manufactured in a 14 nm process with FinFET transistors.
Compared to the Core i5-5350U, the i5-5300U features a higher CPU base clock, but integrates a somewhat slower GPU.
Architecture
Broadwell represents the "Tick" in Intel's Tick-Tock model, which means a shrink of its predecessor Haswell. The new 14 nm manufacturing process with three-dimensional FinFET transistors allows not only improvements in energy efficiency, but also a significantly smaller die size fit for more compact packages and devices.
Further advantages result from the revised microarchitecture of Broadwell. Due to its improved branch prediction, bigger buffer sizes (1500 instead of 1000 entries in the L2 TLB) and other tweaks, the performance per clock has been increased by more than 5 percent over its predecessor. There are also some new instruction set extensions designed for cryptographic applications.
Performance
Thanks to its improved architecture, the Core i5-5300U ends up 5 - 15 percent faster than the slightly lower clocked Core i5-4300U and beats the Core i7-4510U (both Haswell). Thus, the CPU has sufficient power for office and multimedia purposes as well as more demanding applications and multitasking.
Graphics
The integrated HD Graphics 5500 offers 24 Execution Units (EUs) clocked at 300 - 900 MHz. Similar to the CPU core, the GPU architecture (Intel Gen 8) has been thoroughly revised for improved performance-per-clock. Therefore, the HD Graphics 5500 is able to outperform the HD Graphics 4400 (20 EUs) as well as the HD Graphics 5000 (40 EUs), both part of the Haswell generation. Nevertheless, most games as of 2015 will be playable only in low settings.
Broadwell is the first Intel chip to fully support DirectX 11.2 as well as OpenCL 1.3/2.0 and OpenGL 4.3. Video will output natively via DisplayPort 1.2 or HDMI 1.4a. However, the new HDMI 2.0 standard is not supported.
Power Consumption
The i5-5300U is rated at a TDP of 15 W (7.5 W cTDP Down) including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited even for small ultrabooks 11-inches and greater.
The AMD Ryzen 3 3250U is an entry-level, dual-core APU that was announced in 2020. The Ryzen features two Zen cores (SMT is enabled for a total of 4 threads) running at 2.6 GHz to 3.5 GHz and a Radeon RX Vega 3 graphics adapter (3 Compute Units = 192 unified shaders) running at up to 1,200 MHz. The specifications are similar to the older Ryzen 3 3200U, with the lower peak operating temperature of Ryzen 3 3250U (95 °C versus the 105 °C) being the only difference between the two.
AMD Ryzen 3 3250C is a special edition of Ryzen 3 3250U designed for use in Chromebooks. The specifications and performance figures appear to be identical between the two.
Architecture
Unlike the costlier Ryzen 5 3500U, Ryzen 3 3250U is not Zen+ based. It makes use of the ageing Zen architecture and is manufactured on the same 14 nm TSMC process as Ryzen 2000-series laptop-grade processors. This has several repercussions; the limited RAM support is one of them. DDR4-3200, DDR4-2933, DDR4-2666 modules are not supported here. It's just the DDR4-2400, DDR4-2133 and lower on.
The CPU has several PCI-Express 3.0 lanes and is thus compatible with NVMe SSDs (read/write rates will be limited to 3.9 GB/s) as well as discrete graphics cards. Ryzen 3 3250U gets soldered permanently on to the motherboard (FP5 socket interface) and is thus not user-replaceable.
As far as multi-thread benchmark scores are concerned, this Ryzen series chip directly competes with the Core i3-10110U, Core i3-1110G4 and also the Athlon Gold 3150U. While the 3250U is certainly not a powerhouse, mundane tasks such as web browsing and casual gaming pose little problem to it, as of early 2022.
Graphics
The Vega 3 is fairly close to Intel's UHD Graphics 620 as far as performance and capabilities go. The graphics adapter supports UHD 2160p monitors at 60 fps, and it can HW-decode VP9, AVC, HEVC, MPEG-2 and other popular video codecs. The latest AV1 codec is not supported, though. Such a video will have to be decoded via software, with the limited CPU horsepower imposing a hard limit on the resolution that can be played back without stuttering.
The Vega will allow for a bit of light gaming; F1 2021 runs well at 720p / Low, to give you an example. Quality RAM will allow for higher frame rates and the opposite is true as well; please keep in mind that Vega 3 has no VRAM of its own.
Power consumption
Energy efficiency isn't great here. The Ryzen is built with a 14 nm manufacturing process leading to low, as of early 2023, energy efficiency.
The APU has a default TDP, also known as the long-term Power Limit, of 15 W. Laptop makers are free to reduce that value a little, with 12 W being the lower limit, or give it a noticeable bump (up to 25 W are possible). Clock speeds and performance will change accordingly as a result.
While not as power-hungry as the Ryzen 3 3100 or any other desktop chip, the R3 3250U is still not likely to ever feature in a passively cooled laptop, tablet or mini-PC.
