Overseas review summary of Intel 13th generation Core processor 'Raptor Lake', performance difference with rival Ryzen?

Intel's 13th generation Core processor (development code: Raptor Lake) was released on October 20, 2022. Intel

appeals to the 13th generation Core processor that ``single thread performance is improved by up to 15% and multithreaded performance is improved by up to 41%'', and the boost frequency of the top model ``i9-13900K'' may reach 5.8 GHz. It's a hot topic. Several overseas media that quickly obtained such a 13th generation Core processor reported performance verification results, so I summarized them.

◆Spec
The 13th generation Core processors released on October 20, 2022 are 'i9-13900K', ' i7-13700K ', ' i5-13600K ' with built-in GPU and ' i9-13900KF ' and ' i7-13700KF ' without built-in GPU . ”, ” i5-13600KF ”. The specifications of the six CPUs are as follows. Two types of cores, 'Performance-cores (P-core)' that emphasizes processing performance and 'Efficient-cores (E-core)' that emphasizes power efficiency, are installed as in the previous generation Core processor. is a major feature.

◆ Various benchmark scores
The results of overseas media AnandTech's JavaScript benchmark 'Octane 2.0' on various CPUs including 'i9-13900K' and 'i5-13600K' are as follows. The score of 'i9-13900K' surpasses the score of 'Ryzen 9 7950X', the top model of the AMD 'Ryzen 7000' series that appeared in September 2022. On the other hand, 'i5-13600K' recorded a score lower than 'Ryzen 5 7600X'.

The single thread score of 'Cinebench' that can measure the 3D rendering performance of the CPU looks like this. The 'i9-13900K' beats the 'Ryzen 9 7950X' score, while the 'i5-13600K' also beats the 'Ryzen 5 7600X' score.

The multithread score of 'Cinebench' is below. 'i9-13900K' and 'i5-13600K' have recorded scores that surpass rival CPUs as well as single core scores. In particular, it is characteristic that the difference between 'i5-13600K' and 'Ryzen 5 7600X' is large. 'i5-13600K' has a total of 14 P-cores and 8 E-cores, so it is advantageous in multithreading tasks compared to 'Ryzen 5 7600X' with 6 cores It seems

Not all benchmarks are won by Intel. For example, in a test comparing the rendering speed with the 3DCG software 'Blender', rendering was completed faster with 'Ryzen 9 7950X' than with 'i9-13900K'.

◆ Gaming performance
Overseas media The Verge has released the gaming performance verification results when combining “i9-13900K” & “Ryzen 9 7950X” with NVIDIA GPU “ GeForce RTX 4090 ” released in October 2022. Looking at the table below, 'i9-13900K' has a higher frame in games such as ' Metro Exodus ', ' Shadow of the Tomb Raider ', ' Gears 5 ', ' Assassin's Creed Valhalla ', ' Watch Dogs Legion ', and ' Cyberpunk 2077 ' You can see that the rate (fps) is being recorded.

◆ Encoding performance
The results of Ars Technica's verification of the encoding performance of 'i9-13900K' and 'i5-13600K' are as follows. As a result of encoding 1080p30fps with H.264, 'i9-13900K' was able to encode faster than 'Ryzen 9 7950X'.

On the other hand, when encoding 1080p30fps with H.265, 'Ryzen 9 7950X' completes encoding faster than 'i9-13900K'.

◆ Overclocking
Overseas media HotHardware is trying to overclock the 'i9-13900K'. Below is the result of running 'Cinebench' with the overclocked 'i9-13900K'. Overclocking increases the score by about 6.5%.

However, as a result of running '3DMark' that can measure 3D performance, there was no big difference between the overclocked 'i9-13900K' and the rated 'i9-13900K'. HotHardware also points out that in order to maximize the performance of the 'i9-13900K', a high-performance cooling system is required even when operating at the rated level.
