Intel Core i5-L16G7 vs AMD Ryzen 5 4680U

Intel Core i5-L16G7

The Core i5-L16G7 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 3 GHz and 4 small Tremont cores (Atom / Celeron) with up to 2.8 GHz. Using all 5 cores, the CPU can reach up to 1.8 GHz, base clock speed is 1.4 GHz. The CPU does not support HyperThreading / SMT. The rest of the SoC is similar to the Ice Lake chips, like the Gen 11 graphics card with 64 EUs (similar to the Iris Plus G7 but only clocked at 500 MHz and using the UHD Graphics name).

Performance

The average L16G7 in our database is in the same league as the Pentium N6000 and also the Core i3-1110G4, as far as multi-thread benchmark scores are concerned. This kind of performance is only sufficient for basic day-to-day activities as of late 2023.

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

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.

AMD Ryzen 5 4680U

The AMD Ryzen 5 4680U is a semi-custom APU of the Renoir family designed for Microsoft devices. The 4680U integrates six CPU cores based on the Zen 2 microarchitecture clocked at 2.2 GHz (base) to 4 GHz (Boost) with SMT support for a total 12 threads. The two advantages a 4680U has over the older Ryzen 5 4600U are its higher base clock speed and a faster iGPU.

Architecture

The chip is manufactured on the modern 7 nm TSMC process and in part thanks to this fact, AMD advertises a 2x performance per watt improvement over the 12 nm Ryzen 3000 mobile processors. The built-in dual-channel memory controller supports LPDDR4-4266 RAM. Furthermore, 8 MB of L3 cache can be found on the chip.

Just like the other mobile Ryzen 4000 CPUs, a 4680U supports PCI-Express 3.0. Please go to our Renoir processor hub page for additional information on the product family.

Performance

Multi-thread performance is most comparable to the Ryzen 7 4700U and the Core i5-10500H, the latter being a much more power-hungry chip. This makes the Ryzen a more than decent CPU for most tasks, as of early 2022.

Graphics

In addition to the six CPU cores, the APU also integrates a DX 12 compatible Radeon RX Vega 7 graphics adapter with 7 CUs (448 unified shaders) at up to 1,500 MHz. The Vega iGPU will have no trouble HW-decoding AVC, HEVC and VP9 videos, but the newer AV1 codec will only be decoded via software. In terms of gaming, we are looking at an MX150-level performance. Pretty much all games released in 2020 can be played on low to medium settings in 720p on this graphics adapter.

Power consumption

This Ryzen 5 series chip has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop makers - Microsoft, in this case - are free to change to anything between 10 W and 25 W, with clock speeds and performance changing accordingly as a result. Indeed, we saw the CPU consume roughly 23 watts when subjected to our usual stress testing routine.

The 7 nm TSMC process this Ryzen is built with makes for very decent, as of mid 2022, energy efficiency.
