The Intel Core i3-1005G1 is a low-power, Ice Lake family processor (SoC) featuring 2 cores, 4 threads, 4 MB of L3 cache and the UHD G1 (32 EUs) iGPU. It saw the light of day in 2019. The chip is designed for use in highly portable laptops of the more affordable flavour; the CPU cores run at 1.2 GHz to 3.4 GHz which is not a lot.
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 i3 (meaning it 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 i3-1005G1 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 64-bit Windows 11, as well as many Linux distros.
Performance
The average 1005G1 in our database is a disappointment, its multi-thread benchmark scores only matching those of Intel's Core i5-7267U and AMD's Ryzen 3 2300U. This is unfortunately in line with what we've been seeing from other Ice Lake family processors; they tend to be held back by their comparatively low clock speeds. While not as slow as many Celerons and Pentiums, this Core i3 will still look out of place in anything but the most affordable laptops and mini-PCs.
With its long-term CPU power limit of 25 W, the Lenovo V17-IIL 82GX008TGE is among the fastest laptops built around this Core i3 that we know of.
Graphics
The Core i3-1005G1 features the UHD Graphics G1 (32 EUs) graphics adapter running at up to 900 MHz. This DX12-compatible iGPU is not much faster than the dated UHD 620 graphics solution, making it almost useless to gamers, and there are no cutting-edge features such as ray tracing support to be found here, either. The list of supported resolutions tops out at 5120 x 3200, and there is no hardware AV1 codec support meaning such a video will be SW-decoded with rather low energy efficiency. The usual HEVC, AVC and VP9 options are supported, thankfully.
The G1 will drive up to 3 monitors simultaneously, provided the system has the outputs required. Higher-end Ice Lake chips are equipped with the G4 (48 EUs) or the G7 (64 EUs) adapters that are significantly faster.
Power consumption
The Core i3 has a 15 W default TDP (also known as the long-term power limit), a value that laptop makers are allowed to reduce slightly - 13 W being the lower limit - resulting in lower clock speeds and lower performance. Either way, that's a tad too high to allow for passively cooled designs.
The SoC 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.
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).
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.
