AMD Ryzen 3 5300U vs AMD Ryzen 3 3250U vs AMD Ryzen 7 5700U

AMD Ryzen 3 5300U

The AMD Ryzen 3 5300U (not to be confused with the A4-5300, a CPU released in 2012) is a Lucienne family processor designed for use in thin and light laptops. The R3 5300U integrates four cores (quad core) based on the Zen 2 microarchitecture. They are clocked at 2.6 (guaranteed base clock) to 3.8 GHz (Turbo) and support SMT for a total of 8 threads. The chip is manufactured on the modern 7 nm TSMC process. Compared to the older and similar Ryzen 3 4300U (Renoir), the Ryzen 3 5300U offers SMT and slightly higher clock speeds. The faster Ryzen 3 5400U is based on the newer Zen 3 architecture. See our hub page on the Renoir Processors for more information on the Lucienne / Renoir architecture.

In addition to the four CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics adapter with 6 CUs at up to 1500 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 4 MB level 3 cache can be found on the chip.

Performance

The average 5300U in our database matches the Core i5-11300H, the Core i7-11375H and also the Ryzen 5 4500U in multi-thread performance, making it an outstandingly good chip as far as sub-US$700 laptops go.

Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.

Power consumption

The Ryzen 3 series chip has a default TDP of 15 W, a value that laptop makers are allowed to change to anything between 10 W and 25 W with clock speeds and performance changing accordingly as a result. By going for the lowest value possible, it will be possible to build a passively cooled system around the chip, however, most companies will do the opposite to achieve higher performance levels.

The AMD Ryzen 3 5300U is built with TSMC's 7 nm manufacturing process for average, as of mid 2023, energy efficiency.

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.

AMD Ryzen 7 5700U

The AMD Ryzen 7 5700U is an APU of the Lucienne product family designed for leaner laptops. The Ryzen features eight Zen 2 cores clocked at 1.8 GHz (base clock speed) to 4.3 GHz (Boost) as well as a Vega 8 iGPU. Thread-doubling SMT tech is enabled in this CPU for up to 16 concurrent processing threads.

Architecture

In spite of what its name may suggest, Ryzen 7 5700U is not a Zen 3 part, meaning this is a Ryzen 4000 series mobile processor in disguise. Nevertheless, the CPU is manufactured on the modern 7 nm TSMC process and its performance as well as energy efficiency figures are very strong compared to what Intel currently has to offer in this segment.

The Ryzen 7 features 8 MB of Level 3 cache. Its built-in memory controller is designed to work with dual-channel DDR4-3200 or quad-channel LPDDR4-4266 RAM. Unlike the desktop Ryzen 5000 processors, Ryzen 7 5700U does not support PCI-Express 4.0, meaning those speedy NVMe SSDs will be limited to read/write rates of 3.9 GB/s.

The Ryzen gets soldered directly to the motherboard (FP6 socket) and is thus not user-replaceable.

Performance

The average 5700U in our database is in the same league as the Ryzen 7 4800U, Ryzen 7 PRO 5850U, Core i7-1365U, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term CPU power limit of 35 W, the Schenker VIA 15 Pro is among the fastest laptops built around the 5700U that we know of. It can be roughly 50% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

In addition to its eight CPU cores, Ryzen 7 5700U features a Radeon RX Vega series graphics adapter with 8 CUs (= 512 shaders) running at up to 1,900 MHz. This iGPU trails behind the 96 EU Intel Iris Xe Graphics G7 in synthetic benchmarks, yet its real-world performance is good enough for many games released in 2020 and 2021 at reasonable resolutions (up to Full HD 1080p) and low to medium quality. As the Vega has no VRAM of its own, it is paramount that fast system RAM is used.

The graphics adapter definitely supports UHD 2160p monitors at 60 Hz, and will gladly HW-decode AVC, HEVC and VP9-encoded videos. There is no AV1 support here though.

Power consumption

This Ryzen 7 has a default TDP, also known as the long-term power limit, of 15 W; laptop makers are free to change that to anything between 10 W and 25 W, with clock speeds and performance changing accordingly as a result. Most companies will go for a higher value to extract more performance out of the APU. By choosing the lowest value, it will be possible to build a passively cooled system around the chip, too.

The 7 nm TSMC process the R7 5700U is built with makes for decent, as of late 2022, energy efficiency.
