Intel Core i7-1185G7 vs AMD Ryzen 7 5800U vs AMD Ryzen 7 4800U
Intel Core i7-1185G7► remove from comparison
The Intel Core i7-1185G7 is a power-efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP3) that was introduced September 2020. It integrates four Willow Cove processor cores (8 threads thanks to Hyper-Threading). Each core can clock from 1.2 GHz (12 W base clock speed), 3 GHz (28 W base clock speed) to 4.8 GHz (single-core boost). All cores at once can clock at up to 4.3 GHz. At the time of announcement, the i7-1185G7 is the fastest model of the line-up. Since early 2021, the i7-1185G7 supports management features like vPro.
Another novelty is the integrated Iris Xe iGPU based on the completely new Gen 12 architecture. It should offer a significantly higher performance compared to the older Iris Plus G7 (Ice Lake). In the i7-1185G7 it uses 96 EUs and clocks between 400 - 1,350 MHz. The GPU and CPU can together use the 12 MB of L3 cache.
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.
The chip is produced on the second-generation 10 nm Intel SuperFin process that is comparable to the 7 nm TSMC process Ryzen 4000 CPUs are manufactured on.
The operating range of the UP3 series is specified at 12 to 28 Watt. Therefore, the processor is suited for thin and light laptops.
AMD Ryzen 7 5800U► remove from comparison
The AMD Ryzen 7 5800U is a processor for thin and light laptops based on the Cezanne generation. The R7 5800U integrates all eight cores based on the Zen 3 microarchitecture and is the fastest U-series processor at launch. They are clocked at 1.9 (guaranteed base clock) to 4.4 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 7 nm TSMC process.
The new Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2. For desktop processors AMD claims 19 percent on average and in applications reviews showed around 12% gains at the same clock speed.
With the increased clock speed and IPC improvements thanks to Zen 3, the Ryzen 7 5800U should be clearly faster than the 200 MHz lower clocked Ryzen 7 4800U.
In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 GPU with 8 CUs at up to 2000 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.
The TDP of the APU is specified at 15 Watt (default) and can be configured from 10 to 25 Watt by the laptop vendor (most chips are configured higher than 15 Watt). That means the chip is intended for thin and light laptops (but with fans).
AMD Ryzen 7 4800U► remove from comparison
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.

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).
