AMD Ryzen 5 7535U vs Intel Core i7-10750H

AMD Ryzen 5 7535U

The AMD Ryzen 5 7535U is a processor for thin and light laptops based of the Rembrandt refresh generation. The Ryzen packs six of the eight cores based on the Zen 3+ microarchitecture. They are clocked at 2.9 (guaranteed base clock) to 4.55 GHz (Turbo) and support SMT / Hyperthreading (12 threads). The chip is manufactured in 6 nm FinFET at TSMC. The 7535U is the refresh of the 2022 AMD Ryzen 5 6600U and offers 50 MHz higher boost clock at a 3W higher maximum TDP.

The Zen 3+ is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip offers modern features, like support for USB 4 (40 Gbps), PCI-E Gen 4 and DDR5-4800MT/s or LPDDR5-6400MT/s.

The performance should be quite similar to the old Ryzen 5 6600U due to only a slightly increased boost speed (+50MHz) and TDP (28 versus 15-25W).

The integrated GPU Radeon 660M is still a fast iGPUs based on the RDNA2 architecture and offers 6 of the 12 CUs at up to 1.9 GHz.

The Ryzen 7535U is manufactured in 6nm FinFET at TSMC and specified at a TDP of 28W.

Intel Core i7-10750H

The Intel Core i7-10750H is a fast 45 W processor designed for use in larger, beefier laptops. The Comet Lake-H family CPU was launched in mid-2020. It features six cores (twelve threads) running at 2.6 GHz Boosting up to 5 GHz (single-core Boost). The likely all-core Boost frequency is 4.3 GHz. Most of the specs are the same as the 10750H’s direct predecessor, the i7-9750H. The newer model has two advantages over its predecessor in that its Boost frequency is higher and the memory controller can now officially host memory clocked at 2,933 MHz, an upgrade over the 2,666 MHz limitation of the outgoing model.

Architecture

Comet Lake is a yet another revision of the dated Skylake architecture (not unlike the previous Coffee Lake, Whiskey Lake, Kaby Lake families) for similar feature set and performance-per-MHz figures. Core i7-10750H is manufactured on the third-gen 14 nm Intel process that is undeniably inferior to TSMC's 7 nm process, the one AMD’s Ryzen 4000 series laptop-grade processors are manufactured on.

The hexa-core CPU is compatible with up to 128 GB of dual-channel DDR4-2933 RAM and has support for PCI-Express 3.0 and Thunderbolt 3 but not the professional features (vPro, TXT, SIPP) as found in the case of Core i7-10850H.

Both the CPU cores and the iGPU have access to 12 MB of L3 cache. Four PCI-Express 3.0 lanes allow for read/write rates of up to 3.9 GB/s provided a suitably fast NVMe SSD is used.

The 10750H gets soldered permanently on to the motherboard (BGA1440 socket interface) and is thus pretty much impossible to replace.

Performance

Multi-thread performance is most similar to the Core i5-10500H, the Core i5-11400H and also the Ryzen 7 4700U. While perhaps not the best bang for the buck, the i7 is fast enough for any task, gaming included, as of late 2021.

Thanks to its decent cooling solution and a long-term CPU power limit of 75 W, the ThinkPad P15 Gen 1-20ST000DGE is among the fastest laptops built around the 10750H that we know of. It can be about 80% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

We've known the Intel UHD Graphics 630 iGPU for a while. This is the same iGPU the Core i7-9750H and Core i7-8750H processors had. In this i7, the 24 EU iGPU is clocked at 350 MHz to 1,150 MHz.

Intel UHD Graphics 630 will let you connect up to 3 monitors with resolutions of up to 4096x2304@60. The built-in video decoder will happily handle AVC, HEVC, VP9 and other popular video codecs (AV1 is not supported though). This is not a gaming GPU as it is not fast enough to handle most AAA titles released in 2020. At 720p, Escape from Tarkov runs at just 17 fps (low quality preset), to give you an example. As the iGPU has no VRAM of its own, it is paramount that it is mated to fast system RAM.

Power consumption

This Core i7 series chip is built with one of the old 14 nm Intel processes leading to subpar, as of early 2022, energy efficiency.

The Core i7-10750H has a default TDP, also known as the long-term power limit, of 45 W; laptop makers are free to reduce the value somewhat, 35 W being the lower limit, allowing for leaner designs at the cost of performance. Either way, a quality cooling solution is a must.
