AMD Ryzen 3 3250U vs Intel Core i5-9300H

AMD Ryzen 3 3250U

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.

Performance

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.

Intel Core i5-9300H

The Intel Core i5-9300H is a fast processor for laptops with four cores based on the Coffee Lake architecture (2019 Refresh, CFL-HR). The processor clocks at between 2.4 and 4.1 GHz (4 with 4 cores) and can execute up to eight threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. Compared to the predecessor, the Core i5-8300H from 2018, the 9300H is clocked slightly higher (+100 MHz CPU, +50 MHz GPU).

The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).

Performance

The Intel Core i5-9300H should perform similar as the older Core i7-7920HQ (3.1 - 4.1 GHz). The faster Coffee Lake CPUs, like the Core i7-8750H/9750H offers two additional cores and is therefore up to 50% faster in multithreaded benchmarks. Still, the performance of the i5-9300H should be sufficient for even demanding applications and games.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz. The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the i5 is only suited for big laptops with good cooling solutions. Using cTDP-down, the CPU can also be configured to 35 Watt resulting in a reduced performance.
