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

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 4800H

The AMD Ryzen 7 4800H is a Renoir APU designed for larger, more powerful laptops with room for better termals. The Ryzen features eight Zen 2 cores running at 2.9 GHz (base clock speed) to 4.2 GHz (Boost). The CPU also has 8 MB of L3 cache and a Vega series integrated GPU. Thread-doubling SMT tech is enabled in this processor, allowing for up to 16 concurrent processing threads.

Architecture

Ryzen 7 4800H is manufactured on the modern 7 nm TSMC process and in part thanks to this fact AMD promises an up to 2x higher performance-per-watt figure compared to Ryzen 3000 series mobile APUs. This isn't the only noteworthy change however as Zen 2 architecture is leagues ahead of the outgoing Zen+ when it comes to single-core performance. Renoir family processors feature up to 8 CPU cores compared to 4 cores of the previous generation mobile AMD CPUs.

A 4800H will work with dual-channel DDR4-3200 or quad-channel LPDDR4-4266 RAM. The important difference between desktop Ryzen 4000 and mobile Ryzen 4000 processors is that the latter do not have PCI-Express 4.0 support, meaning those blazing-fast NVMe SSDs will be limited to a throughput of 3.9 GB/s.

The Ryzen 7 gets soldered straight to the motherboard (FP6 socket) and is thus not user-replaceable. Please go to our Renoir processor family hub for more information on these CPUs.

Performance

The average 4800H in our database is in the same league as the Core i7-11850H, the Core i7-1360P and also the Ryzen 7 PRO 6850U, as far as multi-thread benchmark scores are concerned. This highlights just how great of a job Renoir designers did, back in the day.

Thanks to its decent cooling solution and a long-term power limit of 45 W, the MSI Alpha 17 A4DEK is among the fastest laptops built around the 4800H that we know of. It can be more than 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

Ryzen 7 4800H features the Radeon RX Vega 7, a 7 CU integrated graphics adapter running at up to 1,600 MHz. The iGPU's underlying architecture is fairly old as of 2021, yet its 448 shaders will let you play many games of 2020 and 2021 as long as you stick to reasonable resolutions and presets. F1 2021 runs well at medium quality, 1080p resolution, to give you an example. A Vega 7 can be as fast as a GeForce GTX 1050 Max-Q, or as slow as an 80 EU Iris Xe; this depends on the benchmark as well as on cooling system performance and TDP settings of a laptop as mentioned above. As the iGPU has no VRAM of its own, it is paramount that fast system RAM is used.

The Vega definitely supports UHD 2160p monitors at 60 Hz. This iGPU is capable of hardware decoding AVC, HEVC and VP9-encoded videos. There is no AV1 support to be found here though. Such a video will have to be SW-decoded leading to much lower energy efficiency.

Power consumption

This Ryzen 7 series chip has a default TDP (also known as the long-term power limit) of 45 W. Laptop makers are allowed to change that to anything between 35 W and 54 W, with clock speeds and performance changing accordingly as a result. The Ryzen 7 4800HS is a 35 W edition of the Ryzen 7 4800H that trades away a bit of performance for lower power consumption. In both cases, an active cooling solution is a must.

Both the 4800H and the 4800HS are built with TSMC's 7 nm process for decent, as of late 2022, energy efficiency.
