AMD will reveal more parameters about Zen4 + Zen4c hybrid architecture Ryzen processor

AMD recently released two new mobile processors, namely R5 8540U and R3 8440U. This release confirms that this series of processors uses the Zen4 Zen4c hybrid architecture, although AMD has not yet released detailed information such as the base frequency and acceleration frequency of the Zen4c "small core"

According to Tom' s Hardware news, AMD’s official processor parameter page will be updated soon to show more parameter information about Zen4c “small core”.

Previous reports have mentioned that the R5 8540U processor consists of 2 Zen4 cores and 4 Zen4c cores, while the R3 8440U includes 1 Zen4 core and 3 Zen4c cores. Regardless of the model, these hybrid architecture processors are equipped with 4CU core graphics. In addition, there is news that early next year, AMD plans to launch an R5 8500G desktop APU. The specifications are expected to be similar to mobile processors, including 2 Zen4 cores, 4 Zen4c cores and 4CU core graphics

Intel The official website can provide clear large-core and small-core frequency information, which is different from Intel's large and small core architecture processors. For example, the i7-14700K's large core frequency ranges between 3.4GHz and 5.6GHz, while the small core frequency fluctuates between 2.5GHz and 4.3GHz. There are some differences between large and small core architectures. The Zen 4c architecture is an optimized version of the Zen 4 microarchitecture that debuted in the AMD EPYC 9704 Bergamo and EPYC 8004 Siena data center processors. Zen 4c retains all the features of Zen 4, including the same instruction set, IPC (instructions per clock cycle) and cache structure. The area of ​​the Zen 4 core is 3.84 square millimeters, while the area of ​​the Zen 4c core is only 2.48 square millimeters, a reduction of 35%

According to AMD’s official PPT data, Zen 4c and Zen 4 are different in all aspects The performance indicators are basically the same. The only difference is that each core of Zen 4 has a 4MB L3 cache, while each core of Zen 4c only has a 2MB L3 cache.

According to AMD data, the IPC of Zen 4c It's the same as Zen 4 at any frequency, which means there's no noticeable difference in performance. The launch of these processors will bring more diverse choices to the mobile and desktop sectors

The above is the detailed content of AMD will reveal more parameters about Zen4 + Zen4c hybrid architecture Ryzen processor. For more information, please follow other related articles on the PHP Chinese website!
