AMD Ryzen 5 5500U vs Intel Core i5-1035G4 vs Intel Core i5-1038NG7

AMD Ryzen 5 5500U

The AMD Ryzen 5 5500U is a hexa-core APU of the Lucienne product family designed for use in ultra-thin, upper mid-range laptops. The processor was unveiled in H1 2021; its six CPU cores are based on the Zen 2 microarchitecture. The cores run at 2.1 GHz (base clock speed) to 4 GHz (highest Boost frequency possible) and feature the thread-doubling SMT technology for a total of 12 threads. The chip is manufactured on the modern 7 nm TSMC process.

One could be forgiven for thinking Ryzen 5 5500U is a renamed Ryzen 5 4500U - which is not the case. Ryzen 5 5500U is most similar to Ryzen 5 4600U, the most noteworthy difference between the two being the faster iGPU model of the former.

In the meantime, Ryzen 5 5600U got a little more lucky; it is based on the newer Zen 3 architecture and it also has higher clock speeds than what a 5500U can boast of.

Architecture

While Ryzen 5 5500U and Ryzen 7 5700U are Zen 2-based processors, the neighbouring Ryzen 5 5600U and Ryzen 7 5800U use AMD's brand-new Zen 3 architecture. This makes the former two a generation older than their names suggest. Still, Zen 2 is nothing to sneeze at, with its high performance-per-Watt and performance-per-MHz figures.

Ryzen 5 5500U supports dual-channel DDR4-3200 and quad-channel LPDDR4-4266 RAM and has 8 MB of Level 3 cache. Unlike desktop-grade Ryzen 5000-series processors, Ryzen 5 5500U is limited to PCI-Express 3.0 (not PCI-Express 4.0; no 7.9 GB/s NVMe SSDs here).

The processor gets soldered permanently on to the motherboard (FP6 socket interface) and is thus not user-replaceable.

Performance

Multi-thread performance is most comparable to the Ryzen 7 4700U and the Core i7-10850H, which is nothing to sneeze at. The Ryzen will have no trouble chewing through pretty much any workload, as of mid 2022.

Thanks to its decent cooling solution and a long-term CPU power limit of around 27 W, the Lenovo IdeaPad Flex 5 14ALC05-82HU006NGE is among the fastest laptops built around the 5500U that we know of. It can be more than 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

The Radeon RX Vega 7 iGPU has 7 CUs at its disposal (64 x 7 = 448 unified shaders) running at up to 1,800 MHz. Its real-life performance is close to what we've seen from GeForce MX250 and Iris Xe Graphics G7 (80 EUs); Mass Effect Legendary Edition (2021) runs well at 1080p resolution, low-to-medium settings, to give you an example. As the iGPU has no VRAM of its own, it is paramount that fast system RAM is used.

The graphics adapter definitely supports UHD 2160p monitors at 60 Hz. It will have no trouble HW-decoding HEVC, AVC, VP9, MPEG-2 and other popular video codecs. There is no AV1 support; AV1-encoded videos will be software-decoded, which six Zen 2 cores will handle with ease.

Power consumption

The APU has a default TDP (also known as the long-term Power Limit) of 15 W. That can be changed to anything between 10 W and 25 W by laptop makers and in many cases they do go for a value higher than 15 W to achieve higher performance levels. On the other hand, by going for the lowest value, it will be possible to build a passively cooled system around the Ryzen 5.

The R5 5500U is manufactured using TSMC's 7 nm process for average, as of mid 2023, average efficiency.

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 i5-1038NG7

The Intel Core i5-1038NG7 or Core i5-1038G7 is a quad-core SoC for laptops and Ultrabooks based on the Ice-Lake-U generation that was announced in Mai 2020 in the refreshed MacBook Pro 13. It integrates four Sunnycove processor cores (8 threads thanks to HyperThreading) clocked at 2 (base) - 3.8 (single core Turbo) GHz. According to Intel the Sunnycove cores achieve 18% more IPCs (Instructions per Clock) and therefore the CPU performance should be similar to the higher clocked Whiskey-Lake and Coffee-Lake predecessors (e.g. Core i7-8559U, 2.7 - 4.5 GHz). The Core i5-1038G7 is the second fastest 28W model of the Ice Lake family after the Core i7-1068G7.

The biggest improvement for Ice-Lake is the integrated Gen 11 graphics card called Iris Plus Graphics. The Core i5-1035G7 integrates the biggest G7 variant with 64 CUs clocked at 300 - 1100? MHz. The Iris Plus G7 should be twice as fast as the predecessors and best the AMD Vega 10 GPU in current Ryzen APUs.

Other improvements for Ice Lake are the AI hardware acceleration and the partial integration of Thunderbolt and Wifi 6 in the chip. The integrated DDR4 memory controller supports modules with up to 3200 MHz (and LPDDDR4 3733).

The Core i5-1038G7 is produced in the new  10nm process at Intel that should offer a comparable performance to the 7nm process at TSMC. The TDP is specified at 28 Watts and therefore the CPU is best used in small multimedia laptops from 13-inch upwards (e.g. like a MacBook Pro 13).
