AMD Ryzen 3 4300U vs Intel Core i3-L13G4

AMD Ryzen 3 4300U

The AMD Ryzen 3 4300U is a processor for thin and light laptops based on the Renoir family. The 4300U integrates four cores based on the Zen 2 microarchitecture (quad core CPU). They are clocked at 2.7 (guaranteed base clock) to 3.7 GHz (Turbo) without SMT / Hyperthreading support (4 threads). The chip is manufactured on the modern 7 nm TSMC process and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips. Compared to the faster Ryzen 5 4000 CPUs (e.g., Ryzen 5 4600U), the Ryzen 3 only offers 4 cores and lower Turbo clock speeds.

In addition to the four CPU cores, the APU also has the Radeon RX Vega 5 integrated graphics card with 5 CUs and up to 1400 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 4 MB of Level 3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.

Performance

The average 4300U in our database matches the Core i5-1035G4 and the Core i5-11300H, both quad-core chips, in multi-thread performance. Technically a lower mid-range CPU, this Ryzen is light years ahead of Intel Pentiums and AMD Athlons that so many sub-US$500 laptops ship with.

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

Power consumption

The Ryzen 3 series chip has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers are free to change to anything between 10 W and 25 W with performance and clock speeds changing accordingly as a result. By going for the lowest value, it is possible to build passively cooled tablets, laptops, mini-PCs around this APU.

The 7 nm TSMC process the Ryzen 3 4300U is manufactured on makes for average, as of mid 2023, energy efficiency.

Intel Core i3-L13G4

The Core i3-L13G4 is an SoC with 5 processor cores based on the Lakefield architecture. It uses one fast Sunny Cove core (known from Ice Lake CPUs but without AVX512) with up to 2.8 GHz and 4 small Tremont cores (Atom / Celeron). Using all 5 cores, the CPU can reach up to 1.3 GHz, base clock speed is 0.8 GHz. The CPU does not support HyperThreading / SMT (= 5 threads max). The rest of the SoC is similar to the Ice Lake chips, like the Gen 11 graphics adapter with 48 EUs (similar to the Iris Plus G4 but only clocked at 500 MHz and using the UHD Graphics name).

Performance

While we have not tested a single system built around the L13G4 as of August 2023, we have tested a certain number of laptops powered by the Core i5-L16G7, a processor that's just a bit faster than the L13G4 (5 cores, 5 threads, up to 3.0 GHz). Based on that, expect the L13G4 to be 5% to 10% slower than the Pentium N6000 and the Core i3-1110G4, as far as multi-thread benchmark scores are concerned.

Needless to say, this kind of performance is only sufficient for basic day-to-day activities as of late 2023.

With a specified TDP of 7 Watt (PL1, 9.5 Watt PL2), the CPU is well suited for thin and light laptops and Windows based tablets. / 2-in-1. Intel claims that the standby power was greatly reduced (91% better compared to the i7-8500Y with 2.5 mW). The SoC is manufactured in 10nm and uses the Intel Foveros 3D Packaging technology. Foveros is used to stack the in 22FFL manufactured I/O die, the compute die in 10nm and up to 8 GB LPDDR4X-4267.
