AMD Ryzen 7 4800U vs Intel Core i7-1065G7

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).

Intel Core i7-1065G7

The Intel Core i7-1065G7 is a power efficient quad-core SoC of the Ice Lake U product family designed for thin laptops and Ultrabooks. It was announced in May 2019 (Computex). The CPU has four Sunnycove processor cores (8 threads thanks to Hyper-Threading) clocked at 1.3 (base) - 3.9 (single core Turbo) GHz. 2 cores can reach 3.8 GHz and all four 3.5 GHz using Turbo Boost. According to Intel the Sunnycove cores achieve 18% more IPCs (Instructions per Clock).

Other improvements for Ice Lake are the AI hardware acceleration and the partial integration of Thunderbolt and Wi-Fi 6 in the chip. The integrated DDR4 memory controller supports modules with up to 3200 MHz (and LPDDDR4 3733).

The biggest improvement of Ice Lake is the integrated Gen 11 graphics adapter called Iris Plus Graphics. The Core i7-1065G7 integrates the biggest G7 variant with 64 EUs clocked at 300 - 1100 MHz. The Iris Plus G7 should be twice as fast as the predecessors and best the AMD Vega 10 GPU from current Ryzen APUs.

Performance

The average 1065G7 in our database is most comparable to the AMD Ryzen 7 2700U and the Intel Core i5-8259U, as far as multi-thread benchmark scores are concerned. This is a so-so result and a direct consequence of Intel's inability to make the best of its brand-new 10 nm node. The Core i7-10710U, a 10th generation processor built with an older 14 nm process, will easily rip a 1065G7 to pieces. That said, the 1065G7 will surely beat a 10710U in terms of energy efficiency.

Thanks to its decent cooling solution and sufficiently high CPU power limits, the Galaxy Book Flex 15-NP950 is among the fastest laptops powered by the 1065G7 that we know of. It can be around 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i7 has a default TDP, also known as the long-term power limit, of 15 W. Laptop makers are free to change that value to anything between 12 W and 25 W with clock speeds and performance changing accordingly as a result. Either way, that's a tad too high to allow for passively cooled designs.

The quad-core Intel CPU is built with Intel's second-gen 10 nm process (not 10 nm SuperFin or Intel 7) for average, as of late 2022, energy efficiency.
