Intel Core i5-11300H vs AMD Ryzen 7 4800U vs AMD Ryzen 5 4680U

Intel Core i5-11300H

The Intel Core i5-11300H is a mid range SoC for thin and light gaming laptops and mobile workstations. It is based on the Tiger Lake H35 generation and was announced early 2021. It integrates four Willow Cove processor cores (8 threads thanks to Hyper-Threading). The base clock speed depends on the TDP setting and can vary from 2.6 (28 W TDP) to 3.1 GHz (35 W). The boost of a single and two cores under load can reach up to 4.4 GHz. All four cores can reach up to 4 GHz. The L3 cache is reduced to 8 MB compared to the 12 MB of the higher end i7 models.

The SoC also has the improved Xe graphics adapter with 80 CUs running at up to 1,300 MHz.

Furthermore, Tiger Lake SoCs add PCIe 4 support (four lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4/USB 4 and Wi-Fi 6 in the chip.

Performance

The average 11300H in our database proves to be an OK lower mid-range CPU, as of early 2022, its multi-thread benchmark scores nearly matching those of the AMD Ryzen 3 5300U. The Core i5 will handle most day-to-day activities with ease, only sweating at the sight of latest triple-A games and similar tasks.

Thanks to its decent cooling solution and a long-term CPU power limit of 40 W, the Nitro 5 AN517-53 is among the fastest laptops built around the 11300H that we know of. It can be around 50% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i5 series chip has a default TDP of 28 W to 35 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, these values are way too high to allow for passively cooled designs.

The i5-11300H is built with Intel's third-generation 10 nm process marketed as SuperFin for lower-than-average, as of mid 2023, energy efficiency.

AMD Ryzen 7 4800U

The AMD Ryzen 7 4800U is a processor for thin and light laptops based on the Renoir architecture. The 4800U integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 1.8 (guaranteed base clock) to 4.2 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in the modern 7 nm process at TSMC and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips. Compared to the similar named Ryzen 7 4800H, the 4800U offers a lower TDP (15 versus 45 Watt) and base clock (1.8 versus 2.9 GHz).

According to AMD, the Ryzen 7 4800U is 4% faster in Cinebench R20 single thread test and 90 % faster in the multithreaded test compared to the fast Intel Core i7-1065G7 (Ice Lake, 4 cores, 3.9 GHz). This means the CPU should be one of the fastest processors in the 15 Watt TDP range and well suited for demanding tasks. The sustained performance however ist strongly depending on the cooling system and the TDP settings of the laptop.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 integrated graphics card with 8 CUs and up to 1750 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.

The TDP of the APU is specified at 15 Watt (default) and can be configured from 10 to 25 Watt by the laptop vendor. That means the chip is intended for thin and light laptops (but with fans).

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.
