AMD Ryzen 7 3700U vs AMD Ryzen 5 4500U

AMD Ryzen 7 3700U

► remove from comparison AMD R7 3700U

The AMD Ryzen 7 3700U is a mobile SoC that was announced in January 2019. It combines four Zen+ cores (8 threads) clocked at 2.3 GHz to 4 GHz with a Radeon RX Vega 10 graphics adapter with 10 CUs (640 Shaders) clocked at up to 1,400 MHz. Specified at 15 Watt TDP, the SoC is intended for thin mid-range laptops. In Chromebooks, AMD calles the APU AMD Ryzen 7 3700C, but with the exact same specifications (and performance).

The Picasso SoCs use the Zen+ microarchitecture with slight improvements that should lead to a 3% IPC (performance per clock) improvements. Furthermore, the 12 nm process allows higher clock rates at similar power consumptions.

The integrated dual-channel memory controller supports up to DDR4-2400 memory. As the features of the Picasso APUs are the same compared to the Raven Ridge predecessors, we point to our Raven Ridge launch article.

The performance of the Ryzen 7 3700U depends heavily on the TDP settings and the cooling solution of the laptop. The average 3700U at the time of writing is only as fast as an older Ryzen 5 2500U (in our performance rating). This comes from the differences of performance in different laptops. For example, the ThinkPad E595 offers a miles better short and long-term CPU performance compared to the HP Envy x360 (see Cinebench R15 loop below). Compared with Intel CPUs, the Ryzen 7 is on par with a Core i5-8250U on average, but e.g. in the E595 it can be matched with higher end Intel counter parts. However, even the slow examples offer enough performance for demanding multi tasking.

AMD Ryzen 5 4500U

► remove from comparison AMD R5 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 outpaces Intel's Core i7-1065G7 (4 cores; up to 3.9 GHz), the fastest consumer-level Ice Lake-U family processor, by a comfortable margin while understandably being noticeably slower than the octa-core Ryzen 7 4700U and Ryzen 7 4800U. In fact, the Ryzen 5's real-world performance approaches that of entry-level H-class Intel Core CPUs such as the i5-9300H and i5-11300H. This is a very potent 15 W CPU delivering an undeniably impressive performance jump over the outgoing Ryzen 5 3500U.

Your mileage may vary depending on how high the Power Limits and how competent the cooling solution of a laptop are.

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

Laptop-grade Ryzen 4000-series processors are rather energy-efficient thanks to the cutting-edge 7 nm process and the mature architecture. Ryzen 5 4500U has a default TDP (also known as the long-term Power Limit) of 15 W that can be changed to anywhere between 10 W and 25 W by an OEM. This makes the chip a good fit for thinner, lighter laptops (with an active cooling solution, preferably) as well as gaming consoles, mini-PCs and other gadgetry.
