The Ryzen 7 4800U powers past Tiger Lake U in Time Spy with 40 percent higher CPU performance

Tipster @TUM_APISAK recently spotted a leaked 3DMark Time Spy benchmark listing for the Ryzen 7 4800U. The 15W 8-core, 16-thread Renoir SoC scored 1045 on the GPU test, but delivered a remarkable 6061 on the CPU test.

This is nearly twice as high as what the Ryzen 7 3780U managed, and nearly 40 percent faster than leaked Time Spy CPU scores for an upcoming Tiger Lake U SoC. 

The leaked 4800U Time Spy scores cement the upcoming Renoir SoC's position as a potential game-changer in terms of power efficiency. Early reports indicated that the Ryzen 7 4800U would potentially offer double the battery life of competing Intel parts. It now appears that it'll also deliver significantly better performance to boot. 

The gains in both performance and efficiency largely stem from AMD's decision to use 7nm Zen 2 cores in its Ryzen 4000 mobile lineup. These offer significant IPC gains over the Zen+ cores in Picasso parts. However, the move to 7nm also allows for higher clocks and higher sustained performance.

The Ryzen 7 4800U's additional physical cores play a big role in better performance, too, with AMD managing to deliver 8 physical cores at a frugal 15W TDP. Tiger Lake U will likely deliver better single-core performance, and this is something we'll update you on as more information comes in.
