AMD Ryzen 7 4800H Mobile APU

The AMD Ryzen 7 4800U not only comes with 8 cores, it also supports simultaneous multithreading, allowing it to process up to 16 threads at the same time.

It has a 4 MB L2 cache and 8 MB L3 cache, with a 2.9 GHz base clock and a 4.2 GHz boost clock. It comes with a Radeon Vega 7 Graphics integrated GPU that runs at 1.6 GHz.

The AMD Ryzen 7 4800H has a nominal TDP of 45 watts, but is configurable by the laptop manufacturer for a TDP of 35 watts to 45 watts.

Like the other AMD Ryzen 4000 Mobile processors, it is fabricated on the 7 nm process, and supports LPDDR4x memory. It also has SmartShift capability, when paired with a separate Radeon GPU.


AMD Ryzen 7 4800H Specifications Compared

Here is a comparison of the AMD Ryzen 7 4800H against the other members of the AMD Ryzen 4000 Mobile family.

Processor Model Cores /

Ryzen 7 4800H 8 / 16 45 W 2.9 GHz 4.2 GHz 4 MB 8 MB Vega 7 1.6 GHz
Ryzen 7 4800U 8 / 16 15 W 1.8 GHz 4.2 GHz 4 MB 8 MB Vega 8 1.75 GHz
Ryzen 5 4700U 8 / 8 15 W 2.0 GHz 4.1 GHz 4 MB 8 MB Vega 7 1.6 GHz
Ryzen 5 4600H 6 / 12 45 W 3.0 GHz 4.0 GHz 3 MB 8 MB Vega 6 1.5 GHz
Ryzen 5 4600U 6 / 12 15 W 2.1 GHz 4.0 GHz 3 MB 8 MB Vega 6 1.5 GHz
Ryzen 5 4500U 6 / 6 15 W 2.3 GHz 4.0 GHz 3 MB 8 MB Vega 6 1.5 GHz
Ryzen 3 4300U 4 / 4 15 W 2.7 GHz 3.7 GHz 2 MB 4 MB Vega 5 1.4 GHz


AMD Ryzen 7 4800H Performance

The AMD Ryzen 7 4800U is targeted directly at the Intel Core i7-9750H, offering :

  • Up to 5% better single-threaded performance
  • Up to 46% better multi-threaded performance
  • Up to 25% faster 4K video encoding on Adobe Premiere
  • Up to 39% faster gameplay physics simulation performance

Thanks to its 2 extra cores and ability to process 4 extra threads, the Ryzen 7 4800H significantly cuts down on the time it takes for content creators to process their work.

Now, its integrated Radeon Vega 7 Graphics is not very fast, which is why AMD did not quote any graphics performance figures. In fact, it has one less core and runs at at a slower speed than the Radeon Vega 8 Graphics in the Ryzen 7 4800U.

Instead, AMD shared with us the PHYSICS test results of the 3DMark Firestrike benchmark. It shows the Ryzen 7 4800H beating not only the Core i7-9750H mobile processor, but also the Core i7-9700K desktop processor! However, it is CPU-only benchmark.

Its gaming performance will definitely be poorer than that of the 15W Ryzen 7 4800U, which means it will likely be paired with a Radeon RX 5500M or RX 5600M, to take advantage of the new AMD SmartShift capability.


AMD Ryzen 7 4800H Availability

One of the first laptops to feature the AMD Ryzen 7 4800H is the ASUS ROG Zephyrus G14, which claims to be the world’s most powerful 14-inch gaming laptop.

It comes with a 14-inch Pantone-validated display with a Full HD or WQHD resolution, and a 120 Hz refresh rate.

It is less than 18 mm thick and weighs just 1.6 kg. ASUS claims a 10 hour battery life, not while gaming though but playing videos.

The Zephyrus G14 and the first slew of laptops to feature the Ryzen 7 4800H will debut in Q1 2020. We will update this article once we know more.
