AMD has finally revealed the much anticipated Ryzen 4000 APUs for laptops. The 7nm Ryzen 4000 APUs come in both U (15-28W) and H (35-45W) series, and offer up to 8 cores 16 threads with boosts up to 4.2 GHz. Preliminary benchmarks show that AMD has managed to significantly close the performance gap with Intel's mobile offerings and is, in fact, leading by large margins. A bevy of new laptops designs are expected to launch this year featuring AMD Ryzen 4000 processors bringing a lot of choice to the consumer.


Given how AMD has managed to decimate Intel in mainstream desktop and HEDT with Ryzen 3000 and Threadripper 3000 platforms, a lot of speculation was in the air as to what AMD would do with its mobile offerings — probably the only area that Intel still rules the roost in the consumer space. A lot of those speculations have come true so, without further ado, let's dive right into the details.

In this article, we will take a comprehensive look at the AMD Zen2 mobile platform and benchmark comparisons available so far with corresponding contemporary offerings from Intel.

The Ryzen 4000 mobile APUs come in three variants — the U-series with a cTDP of 15-28W, the H-series with a cTDP of 35-45W, and the Pro versions of these targeted towards professional users with added security and enterprise management. 

AMD Ryzen 4000 U-Series: AMD's 7nm answer to Intel Ice Lake-U and Comet Lake-U

The Ryzen 4000 U-series is comprised of the following SKUS:

SKUCores/ThreadsBoost/Base Clock (GHz)Cache (MB)GPU CoresGPU Frequency (MHz)TDP (W)
Ryzen 7 4800U8/164.2/1.8128175015
Ryzen 7 4700U8/84.1/1.8127160015
Ryzen 5 4600U6/124.0/2.1116150015
Ryzen 5 4500U6/64.0/2.3116150015
Ryzen 3 4300U4/43.7/2.7651400


The SKUs clearly seem to indicate that AMD has taken good cognizance of Intel's lackluster Comet Lake-U offerings. AMD's move to 7nm has enabled them to cram-in not just enough CPU cores, but an equivalent number of Vega GPU cores as well, all in a 15W TDP envelope. We also managed to get some preliminary benchmark numbers of the Ryzen 7 4800U against Intel's Ice Lake Core i7-1065G7. The 1065G7 is a 10nm part with a fairly capable 64-EU Iris Plus Graphics onboard.

From the data, we get to see that the Ryzen 7 4800U thrashes the Core i7-1065G7 in Cinebench R20 Single Core (+4%), Cinebench R20 Multi Core (+90%), and 3DMark Time Spy (+28%). Content creation workloads also seem to benefit a lot from the Ryzen 7 4800U offering improvements of nearly 40% in Handbrake transcode, 49% in Adobe Premiere Pro, 45% in Chief Design Home Architect, and 27% in PCMark 10 Digital Content Creation workloads compared to the Core i7-1065G7. 

AMD also said that the Ryzen 4000 U-series offers 2x the performance per watt compared to Ryzen 3000 U-series thanks to a 70% process gain and 30% IPC and design improvements. Also on the anvil are LPDDR4X support up to 32 GB, 5x lower power state entry/exit latency, and 20% lower SoC power consumption.

Intel has been the traditional CPU of choice at least when it comes to gaming laptops. AMD didn't quite have a competing offering that can dethrone Intel's H-series 45W chips. That may change this year with the launch of the Renoir Ryzen 4000 APUs.

We have discussed about AMD's lineup of H-series offerings during the company's CES 2020 keynote. Back then, we said that AMD would be launching a Ryzen 9 SKU as well. Now, the company has offered more details into the Ryzen 9 4900H and Ryzen 9 4900HS, and how they fare when compared to Intel's offerings such as the Core i9-9880H

AMD Ryzen 9 4900H

The Ryzen 9 4900H features 8 cores and 16 threads just like the Ryzen 7 4800H but offers higher base and boost clocks at 3.3 GHz and 4.4 GHz, respectively. There are 8 Vega cores on offer clocked at a 1,750 MHz frequency. All this is rated at a 45W TDP. OEMs can configure this TDP at 35W, but that doesn't make it a HS processor.

AMD Ryzen HS series

AMD is pitching the HS series as special APUs that conform to certain standards, similar to what Intel did with Project Athena. As such, the HS APUs are set at a default power consumption of 35W only and OEMs will have to ensure their designs are able to offer sustained performance at this TDP. This also means that AMD will be working only with select OEMs on notebook design and testing. The Asus ROG Zephyrus G14 is one such offering.

AMD indicates three HS processors in the offing. Of these, only the Ryzen 9 4900HS differs a bit from its non-H variant, the Ryzen 9 4900H. The 4900HS offers 8 cores and 16 threads, and a 3 GHz base and 4.3 GHz boost. A Vega 8 iGPU clocked at 1,750 MHz is available and the entire package is rated at a 35W TDP. 

The Ryzen 7 4800HS and Ryzen 5 4600HS are merely HS variants of the Ryzen 7 4800H and the Ryzen 5 4600H and sport similar corresponding specs.

Ryzen 5 4600H6/124.0/3.0116150045
Ryzen 5 4600HS6/124.0/3.0116150035

AMD showed off some comparative metrics of the Ryzen 9 4900HS with the Core i9-9880H. Overall, the Ryzen 9 4900HS shows significant performance gains in most benchmarks with the only regression being shown in PCMark 10's Digital Content Creation test.

We have previously reported about a leaked Cinebench R15 benchmark in which even the Ryzen 7 4800H surpassed most Core i9-9980HK results, so we would believe that Renoir's multicore prowess will come in very handy for productivity on the move.

When paired with the RTX 2060 Max-Q, the Ryzen 9 4900HS seemed to have put up an good numbers in eSports and AAA games. Of course, these are AMD's tests and we will reserve judgement till we get to benchmark this processor ourselves. Till then, check out the benchmarks in the slides below.
