AMD Ryzen 5 4500U Review – TechSpot

This is our first review of AMD’s Ryzen Mobile 4000 U-series processors, the low power variants intended for slim, light, ultraportable laptops. Our exploration will start in the mid-range with the Ryzen 5 4500U, a 6 core and 6 thread part with a 2.3 GHz base and 4.0 GHz boost, alongside 8 MB of L3 cache and 6 Vega GPU compute units clocked up to 1500 MHz. All with a default TDP of 15W.

When you look at AMD’s Ryzen 4000 line-up, this isn’t the lowest-end part, there is a Ryzen 3 4300U on the market with just four cores, but the 4500U is the next step up.

AMD’s segmentation in the U-series mostly deals with core and thread counts, so this Ryzen 5 4500U gets an impressive 6 cores, but without SMT. The 4600U, one step higher adds back in SMT. Then Ryzen 7 parts both have 8 cores, which we’ll hopefully get some hands-on time with soon.

These Ryzen 4000 APUs are Zen 2-based, the same architecture powering 3rd-gen Ryzen desktop CPUs under the Ryzen 3000 brand. Upgrades over previous generation APUs includes the increase in core count, depending on the model, but there’s also a change to the GPU layout.

While this APU still uses the Vega architecture and has fewer compute units, at 8 down from 11, AMD has heavily optimized the design for 7nm, so we see higher clocks and better performance overall.
