[Hardware] AMD Ryzen 9 5980HS 'Cezanne' Defeats Intel Tiger Lake in Early Benchmarks

[Sxynix]

 

The first alleged independent benchmark results of AMD's recently introduced eight-core Ryzen 9 5980HS "Cezanne" laptop processors have been published. AMD's Zen 3-based chip uses integrated Radeon graphics, and, according to the new numbers, beats its predecessor and Intel 10th Gen Comet Lake in single and multi-core workloads, as well as 11th Gen intel Tiger Lake in single-core. Yet, there is a processor that beats AMD's Cezanne. 

Hardware enthusiast @Tum_Apisak found two Geekbench 5 results from the Asus ROG Flow X13. The gaming notebook runs the eight-core Ryzen 9 5980HS at a 3.30 GHz default clock speed and can boost it all the way to a 4.53 GHz. In one case, AMD's Cezanne APU hit a 1,532 single-core score and 8,219 multi-core score. In another case, the processor finished with 1,541 single-core points and 8,224 multi-core points.  

When compared to previous-generation AMD and Intel architectures, the new Cezanne looks very good

The most interesting comparison we can make with a Zen 3 APU is with an Intel Willow Cove processor. Since Intel hasn't launched its eight-core Tiger Lake-H chips yet, the only available CPUs featuring the Willow Cove microarchitecture are quad-core Core i7 1100-series "Tiger Lake-U" processors. These CPUs are not quite meant for gaming machines and, therefore, come inside notebooks with less sophisticated cooling. 

Generally, Intel Core i7-1185G7-based machines score 1,350-1450 single-core points on Geekbench 5. A well-cooled example can hit around 1,550 on a single core and about 5,600 on multi-cores. 

Therefore, it looks like mobile CPUs featuring AMD's Zen 3 and Intel's Willow Cove cores have comparable single-core performance (assuming that both are cooled properly). Naturally, AMD's eight-core gaming APU naturally beats Intel's quad-core CPU in workloads leveraging multiple cores. 

As far as Geekbench 5 results go, AMD's Ryzen 9 5980HS looks like a very potent mobile APU with a 35W TDP. Yet, it's not unbeatable. 

Apple's tiny M1 system-on-chip  (SoC) running at 3.20 GHz scored 11% better than the Ryzen 9 5980HS in single-core workloads and 7% worse in multi-core workloads while consuming about 30% less power, assuming that its TDP is up to 24W. 

Typically, AMD's eight-core Ryzen 9 4900H "Renoir" APUs, based on the Zen 2 microarchitecture, scores about 1,230 single-core points and around 7,100 multi-core points when running at 3.30 / 4.44 GHz clocks in Geekbench 5. Therefore, the new Cezanne APU is apparently 25% faster than its Renoir predecessor in single-core tasks and  about 15% faster in multi-core workloads. 

Cezanne's noticeably higher performance compared to its predecessor can be explained by microarchitectural improvements, as well as a two times larger L2 cache. The Ryzen 94900H is rated for up to a 54W TDP, whereas the new one has a default TDP of 35W. 

A comparison of the new numbers for the Ryzen 9 5980HS to Intel's eight-core Core i9-10885H, Intel's fastest mobile Comet Lake CPU with a locked multiplier, suggests the Ryzen 9 5980HS is 15% faster in single-core workloads and 4% faster in multi-core tasks. 

It should be noted that the Ryzen 9 5980HS numbers haven't been confirmed, so you should take them with a grain of salt.
