As we saw in my previous article, AMD has just nailed it in the mobile SoC market this 2020 and made a healthy start to the year. Not only have they targeted the ultra-thin notebooks and other laptops, but AMD also is not leaving Intel on the gaming CPU front.
Previously we had some leaks regarding the Ryzen 7 4800H and today all the leaks are clarified and we get what we had expected – an 8 core / 16 thread monster mobile processor. These gaming CPUs provide exceptional performance increase than last-gen and are also based on the revolutionary Zen 2 architecture.
Named as the H series of Ryzen 4000 mobile processors, these APUs have a TDP envelope of 45W which is quite sustainable for a gaming laptop. AMD said the processors have a turbo window up to 54W while performing in high-end workloads and gaming.
If we take a glance at the processors we see 3 of them and 2 of them will be available right away and the third one i.e. the Ryzen 7 4800HS will be ASUS exclusive for the first six months.
| Ryzen 4000 45W H-Series CPUs | Cores Threads | Base Freq | Turbo Freq | L2 | L3 | CUs | IGP Freq | TDP |
| Ryzen 7 4800H | 8C / 16T | 2900 | 4200 | 4 MB | 8 MB | 7 CUs | 1600 | 45 W |
| Ryzen 7 4800HS | 8C / 16T | 2900 | 4200 | 4 MB | 8 MB | 7 CUs | 1600 | 35 W |
| Ryzen 5 4600H | 6C / 12T | 3000 | 4000 | 3 MB | 8 MB | 6 CUs | 1500 | 45 W |
The top-of-the-line Ryzen 7 4800H features a base clock of 2.9GHz and a boost of 4.2GHz along with 12MB cache. We see 7CUs of Vega graphics with 1600MHz which is lower than we saw in the Ryzen 7 4800U. The higher TDP helps the SoC to provide higher base clock frequency of 2.9GHz.
In the coming months, we can expect the Ryzen 9 product stack as well with a fully enabled IGP as well as a small bump in graphics frequency. Interestingly the Ryzen 7 4800HS, which is the ASUS-exclusive is said to be made by ASUS and AMD together helping to deliver the full 45W performance and frequency but in a 35W envelope.
The Ryzen 4000H series will directly compete against Intel’s top-of-the-line Intel H-series CPUs, whose current flagship is the flagship Core i9 9980HK. AMD even said that the new Ryzen gaming chips can beat the Core i9 9980HK in most areas, single-threaded, multithreaded, and on integrated graphics as well.
AMD has also introduced a new feature called AMD SmartShift exclusively for its H-series Ryzen 4000 processors which is a power delivery mechanism. As the laptop manufacturers will be using the APU as well as a discrete GPU, SmartShift will automatically adjust the power budget between the CPU and the discrete GPU for the max power budget allocated for the laptop.
In terms of real-world performance and benchmarks this feature can manually be turned on/off, AMD says this delivers 10% better framerates in The Division 2, and 12% faster Cinebench R20 NT.
Overall, these new powerful 7nm processors can deliver great performance and finally we can get almost desktop-like performance in a mobile form factor, thanks to AMD. We will see the Ryzen 4000H processors in laptops in the Q1 of 2020 itself, just can’t wait to test them!
