Intel Core i5-1035G1 vs AMD Ryzen 7 4800U vs AMD Ryzen 7 4700U

Intel Core i5-1035G1

The Intel Core i5-1035G1 is a low-power, Ice Lake family processor (SoC) featuring 4 cores, 8 threads, 6 MB of L3 cache and the UHD G1 (32 EUs) iGPU. It saw the light of day in H2 2019. The chip is designed for use in highly portable laptops; its CPU cores run at 1.0 GHz to 3.6 GHz, with only 3.2 GHz achievable if all the cores are loaded.

Unlike the costlier Core i5-1035G4, the 1035G1 has the 32 EU UHD Graphics G1 iGPU at its disposal as opposed to the more powerful 48 EU Iris Plus G4; CPU cores run at a slightly lower clock rate in the case of the 1035G1, too.

Architecture & Features

Ice Lake family chips are powered by Sunny Cove CPU cores.The latter aim to do what Palm Cove cores (that we never really got a chance to get a taste of) were expected to do, delivering a double-digit IPC uplift over the venerable Skylake architecture thanks to a range of small improvements across the board including scheduler improvements, larger caches and buffers, and support for new instruction sets.

Thunderbolt 3 support is built right into the Core i5 (meaning the latter has several PCIe 3 lanes exclusive to Thunderbolt devices, reducing the number of additional components required for Thunderbolt to work) and so is Intel CNVi Wi-Fi 6 support (making it easier for Intel to sell its proprietary WLAN cards to laptop makers). The Core i5-1035G1 also has the DL Boost and GNA features for applications centered around machine learning.

The 4 GT/s bus is indicative of a consumer-grade chip, since CPUs for gaming laptops and portable workstations usually employ the faster 8 GT/s bus. RAM support is nothing to sneeze at, at up to DDR4-3200 or LPDDR4-3733. NVMe SSDs are supported, with data transfer rates limited to 3.9 GB/s (this is what four PCIe 3 lanes are good for). SATA drives and even eMMC chips are also natively supported here.

This is not a user-replaceable CPU, as it gets permanently soldered to the motherboard (BGA1526 socket interface).

OS support is limited to 64-bit Windows 10 and Windows 11, as well as many Linux distros.

Performance

The Core i5-1035G1 is a lower mid-range CPU, as of mid 2022. It is good for more than just the basics while being no match for true high-performers such as the mighty Core i7-10850H.

According to our in-house testing, the Core i5 delivers multi-thread performance that is similar to what the Core i7-10610U, the Core i7-1160G7 and the Ryzen 5 PRO 3500U have to offer. Your mileage may vary depending on how competent the cooling solution of your system is and how high the CPU power limits are.

The Lenovo IdeaPad 5 15IIL05 is among the fastest laptops featuring the 1035G1 that we have tested.

Graphics

The UHD Graphics G1 is based on Intel's Gen 11 architecture. The UHD Graphics runs at up to 1,050 MHz and has 32 EUs for fairly unimpressive performance; the Iris Plus G4 has 48 EUs while the Iris Plus G7 has 64 EUs, for reference. This iGPU will drive up to 3 monitors simultaneously and is DX12-compatible. The resolution options are capped at 5120 by 3200. There is no hardware AV1 codec support here, meaning such a video will be SW-decoded with rather low energy efficiency. The usual HEVC, AVC and VP9 codecs are supported, thankfully.

The UHD Graphics is significantly faster than the UHD Graphics 620, yet it's still not as good as a proper discrete graphics card would be. It will let one play certain games, F1 2020 included, provided one is content with the 720p resolution and low quality settings.

Power consumption

The Core i5-1035G1 has a default TDP (also known as the long-term Power Limit) of 15 W. Laptop makers are free to increase that value somewhat, with 25 W being the upper limit, or reduce it (values as low as 13 W are possible). Clock speeds and performance will change accordingly as a result. Either way, an active cooling solution will be required to dissipate the heat.

The chip is manufactured on Intel's second-generation 10 nm process (not "10 nm SuperFin" or "Intel 7") for average, as of late 2022, 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 7 4700U

The AMD Ryzen 7 4700U is a processor for thin and light laptops based on the Renoir architecture. The 4700U integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 2 (guaranteed base clock) to 4.1 GHz (Turbo). There is no support for the thread-doubling SMT tech. 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 R7 4800U, the 4700U offers slightly lower clock speeds and no support for SMT / Hyperthreading.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics card with 7 CUs and up to 1600 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.

Performance

The average 4700U in our database proves to be a rather competent little processor. It trades blows with the much more power-hungry Intel Core i7-10750H, as far as multi-thread benchmark scores are concerned. While it fails to get far enough away from the more affordable Ryzen 5 4600U, this Ryzen 7 is still a good CPU for most tasks.

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

Power consumption

The Ryzen 7 4700U is a 15 W chip. However, laptop makers are allowed to change that value to anything between 10 W and 25 W, with clock speeds and long-term performance changing accordingly as a result. By going for the lowest value, it is possible to build a passively cooled system around the APU.

The fairly modern 7 nm TSMC process this Ryzen is manufactured on makes for above average, as of mid 2022, energy efficiency.
