Intel Core i5-1035G7 vs AMD Ryzen 5 4500U vs AMD Ryzen 7 4800H

Intel Core i5-1035G7

The Intel Core i5-1035G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Ice -Lake-U generation that was announced in Mai 2019 (Computex). It integrates four Sunnycove processor cores (8 threads thanks to HyperThreading) clocked at 1.2 (base) - 3.7 (single core Turbo) GHz. 2 cores can reach 3.6 GHz and all four 3.3 GHz using Turbo Boost. According to Intel the Sunnycove cores achieve 18% more IPCs (Instructions per Clock). The Core i5-1035G7 is the second fastest Ice Lake-U chip at the time of announcement in 2019.

The biggest improvement for Ice-Lake is the integrated Gen 11 graphics adapter called Iris Plus Graphics. The Core i7-1065G7 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).

Performance

The average 1035G7 in our database is in the same league as the Ryzen 3 4300U and the Core i5-10210U, as far as multi-thread benchmark scores are concerned. Which isn't bad at all as of late 2021. The Core i5-1035G4 and the Core i5-1035G1 are two other chips that nearly match the 1035G7 in multi-thread performance.

Thanks to its decent cooling solution and a long-term CPU power limit of 22 W, the Surface Laptop 3 13 is among the fastest laptops built around the 1035G7 that we know of. It can be at least 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i5 has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers are allowed to change to anything between 12 W and 25 W if required with clock speeds and performance changing accordingly. Those values are a little too high to allow for passively cooled designs.

The processor is built with Intel's second-gen 10 nm process for decent, as of late 2022, energy efficiency.

AMD Ryzen 5 4500U

The AMD Ryzen 5 4500U is an upper mid-range, hexa-core processor of the Renoir product family. The APU was unveiled in H1 2020; it is designed for use in thinner, lighter laptops. Its six Zen 2 CPU cores run at 2.3 GHz (base clock speed) to 4.0 GHz (highest Boost frequency possible). Ryzen 5 4500U features the Vega 6 iGPU.

The sole advantage of Ryzen 5 4600U over Ryzen 5 4500U is the thread-doubling SMT technology support. The former has SMT while the latter does not.

Architecture

Zen 2 is a resounding success, delivering massive improvements over outgoing Zen Plus-based processors. Ryzen 5 4500U is manufactured on the cutting-edge 7 nm TSMC process; it is compatible with dual-channel DDR4-3200 or quad-channel LPDDR4-4266 memory. This processor has 8 MB of Level 3 cache.

While the APU uses Zen 2 cores just like the desktop-grade Ryzen 3000-series processors do, Ryzen 7 3800XT included, it does does not have PCI-Express 4.0 support. It does feature several PCI-Express 3.0 lanes for connecting discrete graphics cards, SSDs and other devices. 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.

Ryzen 5 4500U gets soldered permanently on to the motherboard (FP6 socket interface) and is anything but user-replaceable.

Performance

The average Ryzen 5 4500U in our database nearly matches the Core i5-11300H, the Core i5-11320H and also the AMD Ryzen 3 5300U as far as multi-thread benchmark scores are concerned - thus delivering an undeniably impressive performance jump over the outgoing Ryzen 5 3500U.

Thanks to its decent cooling solution and a long-term power limit of 38 W, the Xiaomi RedmiBook 16 R5 is among the fastest systems powered by the R5 4500U that we know of. It can be about 20% faster in CPU-bound workloads than the slowest system built around the same chip in our database, as of August 2023.

Graphics

Just like its name suggests, the Radeon RX Vega 6 graphics adapter has 6 Compute Units (6 x 64 = 384 unified shaders). In the case of Ryzen 5 4500U, this graphics adapter runs at up to 1,500 MHz. The iGPU definitely supports UHD 2160p monitors at 60 Hz; it will have no trouble HW-decoding HEVC, AVC, VP9, MPEG-2 and other widespread video codecs. AV1 is not supported though; such a video will have to be software-decoded for much lower energy efficiency.

Vega 6 will let you play many titles of 2020 and 2021 as long as you stick to low settings and low resolutions. F1 2021 (720p, Low) runs at 32 fps; Outriders (720p, Low) runs at 27 fps, to give you an example or two. As the iGPU has no VRAM of its own, it is paramount that fast system RAM is used.

Power consumption

This Ryzen chip is very energy efficient, as of mid 2022, thanks to the cutting-edge 7 nm TSMC manufacturing process and the mature Zen 2 architecture.

The Ryzen 5 4500U 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 if required, a right they use more often than not. Clock speeds and performance will change accordingly as a result. By going for the lowest value, it will be possible to use the APU as the heart of a passively cooled tablet, laptop, mini-PC.

AMD Ryzen 7 4800H

The AMD Ryzen 7 4800H is a Renoir APU designed for larger, more powerful laptops with room for better termals. The Ryzen features eight Zen 2 cores running at 2.9 GHz (base clock speed) to 4.2 GHz (Boost). The CPU also has 8 MB of L3 cache and a Vega series integrated GPU. Thread-doubling SMT tech is enabled in this processor, allowing for up to 16 concurrent processing threads.

Architecture

Ryzen 7 4800H is manufactured on the modern 7 nm TSMC process and in part thanks to this fact AMD promises an up to 2x higher performance-per-watt figure compared to Ryzen 3000 series mobile APUs. This isn't the only noteworthy change however as Zen 2 architecture is leagues ahead of the outgoing Zen+ when it comes to single-core performance. Renoir family processors feature up to 8 CPU cores compared to 4 cores of the previous generation mobile AMD CPUs.

A 4800H will work with dual-channel DDR4-3200 or quad-channel LPDDR4-4266 RAM. The important difference between desktop Ryzen 4000 and mobile Ryzen 4000 processors is that the latter do not have PCI-Express 4.0 support, meaning those blazing-fast NVMe SSDs will be limited to a throughput of 3.9 GB/s.

The Ryzen 7 gets soldered straight to the motherboard (FP6 socket) and is thus not user-replaceable. Please go to our Renoir processor family hub for more information on these CPUs.

Performance

The average 4800H in our database is in the same league as the Core i7-11850H, the Core i7-1360P and also the Ryzen 7 PRO 6850U, as far as multi-thread benchmark scores are concerned. This highlights just how great of a job Renoir designers did, back in the day.

Thanks to its decent cooling solution and a long-term power limit of 45 W, the MSI Alpha 17 A4DEK is among the fastest laptops built around the 4800H that we know of. It can be more than 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

Ryzen 7 4800H features the Radeon RX Vega 7, a 7 CU integrated graphics adapter running at up to 1,600 MHz. The iGPU's underlying architecture is fairly old as of 2021, yet its 448 shaders will let you play many games of 2020 and 2021 as long as you stick to reasonable resolutions and presets. F1 2021 runs well at medium quality, 1080p resolution, to give you an example. A Vega 7 can be as fast as a GeForce GTX 1050 Max-Q, or as slow as an 80 EU Iris Xe; this depends on the benchmark as well as on cooling system performance and TDP settings of a laptop as mentioned above. As the iGPU has no VRAM of its own, it is paramount that fast system RAM is used.

The Vega definitely supports UHD 2160p monitors at 60 Hz. This iGPU is capable of hardware decoding AVC, HEVC and VP9-encoded videos. There is no AV1 support to be found here though. Such a video will have to be SW-decoded leading to much lower energy efficiency.

Power consumption

This Ryzen 7 series chip has a default TDP (also known as the long-term power limit) of 45 W. Laptop makers are allowed to change that to anything between 35 W and 54 W, with clock speeds and performance changing accordingly as a result. The Ryzen 7 4800HS is a 35 W edition of the Ryzen 7 4800H that trades away a bit of performance for lower power consumption. In both cases, an active cooling solution is a must.

Both the 4800H and the 4800HS are built with TSMC's 7 nm process for decent, as of late 2022, energy efficiency.
