Intel Core i5-7500 vs Intel Core i5-1035G4 vs Intel Core i7-7600U

Intel Core i5-7500

The Intel Core i5-7500 is a fast mid-range quad-core processor for desktops based on the Kaby Lake architecture and was announced in January 2017. It offers four cores (no HyperThreading and therefore also only 4 threads at once) that run at 3.4 - 3.8 GHz.

Architecture

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Performance

The performance of the i5-7500 is comparable to a mobile Core i7-7700HQ. Therefore, the performance is sufficient even for demanding applications and games.

Graphics

The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1100 MHz. The performance depends a lot on the memory configuration; it should be comparable to a dedicated Nvidia GeForce 920M in combination with fast DDR4-2133 dual-channel memory.

Contrary to Skylake, Kaby Lake now supports hardware decoding for H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors, which were announced in January, should also support HDCP 2.2.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency slightly. Intel still specifies the TDP with 65 Watts, which is a lot more than the 45 Watts of the mobile Kaby-Lake-H CPUs but less than e.g. the Core i5-7600K (91 Watt).

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.

Intel Core i7-7600U

The Intel Core i7-7600U is a fast dual-core processor for notebooks based on the Kaby Lake architecture and was announced in January 2017. It integrates 2 CPU cores with Hyper-Threading support clocked at 2.8 - 3.9 GHz (2 core Turbo also 3.9 GHz). Besides two cores, the processor is also equipped with the HD Graphics 620 GPU as well as a dual-channel memory controller (DDR3L-1600/DDR4-2400). It is manufactured in a 14nm process with FinFET transistors.

Architecture

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Performance

With 2.5 to 3.9 GHz, the Core i7-7600U clocks significantly higher than the old Core i7-6500U (2.5 - 3.1). That means, the i7-7600U is (at the time of announcement in beginning of 2017) the fastest dual core processor for laptops. The performance is sufficient for demanding tasks (except some games that may need four real cores).

Graphics

The integrated Intel HD Graphics 620 has 24 Execution Units (similar to previous HD Graphics 520) running at 300 - 1150 MHz. The performance depends a lot on the memory configuration; it should be comparable to a dedicated Nvidia GeForce 920M in combination with fast DDR4-2133 dual-channel memory.

Contrary to Skylake, Kaby Lake now supports hardware decoding for H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors, which were announced in January, should also support HDCP 2.2.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. Intel still specifies the TDP with 15 Watts, but it can also be reduced to 7.5 Watts by the notebook manufacturers (cTDP down). This will obviously affect the performance, because the Turbo Boost cannot be maintained for longer periods.
