Apple M2 vs Intel Core i5-1035G4

Apple M2

The Apple M2 is a System on a Chip (SoC) from Apple that is found in the late 2022 MacBook Air and, MacBook Pro 13. It offers 8 cores divided in four performance cores and four power-efficiency cores. The big cores offer 192 KB instruction cache, 128 KB data cache, and 16 MB shared L2 cache (up from 12 MB). The four efficiency cores are a lot smaller and offer only 128 KB instruction cache, 64 KB data cache, and 4 MB shared cache. The efficiency cores (E cluster) clock with  up to 2,4 GHz, the performance cores (P cluster) with up to 3,5 GHz and therefore higher than the M1 cores. The architecture should be similar to the A15 (iPhone 13) with Avalanche and Blizzard cores.

The chip features a unified memory architecture for the CPU and GPU cores and supports up to 24 GB LPDDR5-6400 for a bandwidth of up to 100GB/s.

According to Apple, the M2 offers a 18% higher CPU performance at the same power consumption level compared to the Apple M1. In our tests, the MacBook Pro 13 with active cooling was able to reach the 18% in Geekbench Multi. In other benchmarks we measured 12 to 15% gains compared to the M1. Therefore, the performance is now near the M1 Pro with 8 cores. The passively cooled MacBook Air may however suffer from throttling in longer load scenarios.

The integrated graphics card in the M2 offers 8 or 10 cores and a peak performance of 3.6 TFLOPs.

Furthermore, the SoC integrates a fast 16 core neural engine with a peak performance of 16 TOPS (for AI hardware acceleration), a secure enclave (e.g., for encryption), Thunderbolt / USB 4 controller, an ISP, and media de- and encoders.

The Apple M2 includes 20 billion transistors (up from the 16 billion of the M1) and is manufactured in the second generation 5nm process at TSMC (most likely N5P). The power consumption is rated at 20W what we also measured under CPU load.

Intel Core i5-1035G4

The Intel Core i5-1035G4 is a low-power, Ice Lake family processor (SoC) featuring 4 cores, 8 threads, 6 MB of L3 cache and the Iris Plus G4 (48 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 1.1 GHz to 3.7 GHz, with only 3.3 GHz achievable if all the cores are loaded.

Unlike the costlier Core i5-1035G7, the 1035G4 has the 48 EU Intel iGPU at its disposal as opposed to the more powerful Iris Plus G7 (64 EUs); CPU cores have a slightly lower base clock speed in the case of the 1035G4, 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 CNVi Wi-Fi 6 support (making it easier for Intel to sell its proprietary WLAN cards to laptop makers). The Core i5-1035G4 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 average 1035G4 in our database is very close to the Ryzen 5 2500U and the Core i5-10310U, as far as multi-thread benchmark scores are concerned. This makes it a mid-range chip, as of late 2021. It can even be used for a bit of gaming if mated to a decent graphics card.

The Acer Spin 3 SP314-54N-56S5 is one of the fastest laptops with this chip that we have tested. Thanks to the power limit 1 of 16.5 W, the Acer can be roughly 30% faster than the slowest system with the 1035G4 we know of, depending on the circumstances.

Graphics

The Iris Plus G4 (48 EUs) runs at up to 1.05 GHz. This is a rather decent iGPU that can be as fast as Nvidia's GeForce MX110 or even MX130, depending on the circumstances. It will handle many games at 1080p or 720p provided one is content with low or medium quality settings, respectively.

This DX12-compatible graphics adapter will drive up to 3 monitors with resolutions as high as 5120 x 3200. There is no support for ray tracing here and no hardware support for the latest AV1 codec; the usual HEVC, AVC and VP9 codecs are supported, thankfully.

Power consumption

This 10th generation Intel Core i5 processor has a default TDP of 15 W (also known as the long-term power limit). Laptop makers are allowed to change that value to anything between 12 W and 25 W, with clock speeds and performance changing accordingly. This means the CPU is too power-hungry to be used as the base of a passively cooled laptop, tablet, mini-PC.

The Core i5-1035G4 is manufactured on Intel's 2nd generation 10 nm process (not "10 nm SuperFin" or "Intel 7") for average energy efficiency, as of early 2023.
