The Ryzen 7 5800 U is AMD’s response to Intel’s Tiger Lake and is their fastest readily available chip for ultraportable and ultrathin laptop computers. This is the very first Ryzen Mobile 5000 U-series processor to land in our workplace despite the fact that it was revealed method back in January, however like numerous releases this year, it’s taken a little additional time to really strike the marketplace.

When Intel released Tiger Lake in 2015, they had the ability to recover the efficiency crown in lots of crucial work for thin and light laptop computers. While they just had up to 4 CPU cores compared to 8 in AMD’s line-up, Intel had the ability to provide class-leading single thread and graphics efficiency, topping the charts in lots of lighter applications you may anticipate to utilize on this sort of makers.

However with Ryzen 5000, AMD is back to nullify Intel’s essential benefit. The Ryzen 7 5800 U maintains its 8-core CPU style, double the cores of Intel’s Core i7-1165 G7 and 1185 G7, however bumps up those cores to utilize the more recent Zen 3 architecture. With a substantial bump to IPC, an upgraded core complex with a single CCX, double the L3 cache, and power optimizations– AMD declares much greater single-thread efficiency versus Ryzen 4000 and multi-thread gains that will just extend AMD’s lead on Intel.

Nevertheless, not every location to Ryzen Mobile 5000 has actually been upgraded. The Ryzen 7 5800 U includes the very same Vega GPU style, with 8 calculate systems, which might not suffice adequate to beat Intel’s Xe GPU. The multimedia engine, memory controller, PCIe design and other functions likewise stay extremely comparable to their last-gen APU.

AMD’s line-up is a little complicated because not all Ryzen Mobile 5000 U-series processors utilize Zen 3 CPU cores. The Ryzen 7 5800 U we’re taking a look at today does, it’s their brand-new Cezanne pass away. The Ryzen 7 5700 U that sits straight listed below it stays a Zen 2 processor, utilizing a revitalized die AMD are calling Lucienne. This is something to bear in mind (and more described here) when purchasing a brand-new Ryzen 7 5000 series chip.

The Ryzen 7 5800 U loads 8 cores and 16 threads, with a base clock of 1.9 GHz and an optimum increase frequency of 4.4 GHz. There’s 16 MB of L3 cache and 4MB of L2, together with 8 Vega calculate systems clocked as much as 2.0 GHz. This is all constructed on TSMC’s 7nm production node with a default TDP of 15 W. The 5800 U winds up as a completely opened Cezanne pass away however isn’t rather as extremely clocked as AMD’s H-series chips that, for instance, push increase frequencies approximately 4.8 GHz.

In spite of striking the outright greatest frequencies this silicon can do, the Ryzen 7 5800 U does supply some frequency enhancements over the Ryzen 7 4800 U. The base clock is 100 MHz greater and the increase clock 200 MHz greater, which remains in addition to the IPC gains of Zen 3 versus Zen 2. The GPU is likewise clocked 250 MHz greater although it utilizes essentially the exact same Vega style and calculate system count. We likewise get double the L3 cache as anticipated.

The system we’re utilizing for evaluating the 5800 U is Asus brand-new ZenBook 13, which is a really compact slim and light note pad with a remarkable OLED screen. I’m delighted this new age of ultraportables pertaining to market are utilizing OLED screens, since this thing is seriously outstanding in regards to contrast, black levels and colors. Although it’s simply a 1080 p screen, the advantages to utilizing OLED are huge, consisting of correct HDR performance.

Aside from OLED, we’re likewise getting the Ryzen 7 5800 U in several power modes, 16 GB of LPDDR4X-3733 memory, and in my system 1TB of storage. The construct quality is rather good, I enjoy how portable this thing is, it has a great big touchpad and a good keyboard. And that’s without even talking about efficiency. It does absence Thunderbolt which is a typical function omission on AMD laptop computers.

Like our previous U-series processor screening, today we are benchmarking the Ryzen 7 5800 U in both its 15 W and 25 W power setups (long term power limitations). As with all laptop computers checked, there’s likewise an increase duration, in the case of this laptop computer up to about 30 W. The 5800 U will be pitted up versus other laptop computer processors likewise evaluated at 15 W and 25 W, although when it comes to Tiger Lake, we have actually run Intel’s style at 15 W and 28 W, as 28 W is the greatest power config readily available compared to 25 W for AMD.

Our criteria charts are approximately outcomes drawn from numerous laptop computers performing at the very same long term power setup. Here you can see the complete list of laptop computers we have actually checked. We evaluate by doing this to provide you a basic concept of how laptop processors compare without variables like OEM setups and cooling styles having much impact.

For this evaluation, we ought to likewise keep in mind that we re-tested the Ryzen 7 4800 U with increase habits that carefully matches the 5800 U in this ZenBook 13, so we might have the outright finest apples-to-apples contrast in between AMD processor generations.


In Cinebench R20 we get our very first take a look at the Ryzen 7 5800 U’s multi-threaded efficiency. At 15 W we do not see a substantial efficiency boost over the Ryzen 7 4800 U, simply a number of percent all up. At the greater 25 W setup, the 5800 U ends up about 5%ahead of the older style.

This little efficiency uplift permits the 5800 U to extend its lead on Intel. In the greater power class, AMD holds a 75 to 80 percent efficiency lead, which is definitely huge when comparing 2 processors at a comparable rate point. At the lower 15 W power specification, AMD’s style seems more effective once again, pressing their lead up to over a 2x benefit. This sees AMD’s CPU being in the area of H-series processors like the Core i7-10750 H and Core i9-10980 HK for multi-thread efficiency.

The huge concern around Ryzen Mobile 5000 however isn’t multi-thread efficiency, however single-thread efficiency, and how that compares to Tiger Lake. The outcomes are appealing: the 5800 U is 14
