Advanced Micro Devices (AMD) has been on the forefront of the technological world with its innovative microprocessors and graphics processing units. AMD’s recent foray into mobile processors has yielded some impressive results, and the Ryzen 5 7640U is the latest addition to its lineup. This six-core processor with six Zen 4 cores and an integrated Radeon 760M iGPU featuring 8 RDNA 3 cores has been spotted on Geekbench, and the results are impressive. The processor is almost as fast as the Ryzen 9 6900HX, and it brings considerable performance gains over its predecessor, the Ryzen 5 6600U.
Single-Core Performance:
The Geekbench results for the Ryzen 5 7640U show that it has a single-core score of 1896 points. This puts it ahead of the Ryzen 9 6900HX and the Ryzen 5 6600U by 300 points, which translates to a 25% performance uplift. This is a significant increase in performance and is likely due to the Zen 4 architecture, which brings improvements in IPC (instructions per clock) and cache sizes.
Multi-Core Performance:
In multi-core mode, the Ryzen 5 7640U shows even more impressive gains over its predecessor, the Ryzen 5 6600U. The processor is 60% faster in multi-core loads, which is a significant improvement. However, it lags behind the Ryzen 9 6900HX by approximately 15%, which is understandable as the Ryzen 9 has two more cores than the Ryzen 5 7640U.
Architecture and Features:
The Ryzen 5 7640U is based on AMD’s Zen 4 architecture, which is the latest iteration of the Zen architecture. The Zen 4 architecture brings improvements in IPC, cache sizes, and power consumption, which all contribute to better performance. The processor also comes with 1 MB of L2 cache per core, which is a significant improvement over its predecessor, the Ryzen 5 6600U, which had only 512 KB of L2 cache per core.
The Ryzen 5 7640U also comes with an integrated Radeon 760M iGPU featuring 8 RDNA 3 cores. The RDNA 3 architecture brings improvements in performance and power consumption over its predecessor, the RDNA 2 architecture. The integrated graphics are capable of handling basic gaming and graphics tasks, which is a significant improvement over the Ryzen 5 6600U, which had only basic integrated graphics.
Power Consumption:
The minimum TDP of the Ryzen 5 7640U is not stated in the Geekbench entry, but it is expected to be around 15 W. This is a significant improvement over its predecessor, the Ryzen 5 6600U, which had a TDP of 15 W. The lower TDP means that the Ryzen 5 7640U will consume less power, which is beneficial for battery life in mobile devices.
Comparison with Desktop-Grade Processors:
Benchleaks on Twitter has estimated that the Ryzen 5 7640U is 8.2% faster in single-core mode but 17.6% slower in multi-core mode compared to a Ryzen 7 5800X desktop-grade processor. This is not surprising as desktop-grade processors have higher TDPs, which allows them to perform better than mobile processors. However, the fact that the Ryzen 5 7640U is able to come close to a desktop-grade processor in single-core mode is impressive.
Conclusion:
The Ryzen 5 7640U with six Zen 4 cores spotted on Geekbench is an impressive addition to AMD’s lineup of mobile processors. It brings significant performance gains over its predecessor, the Ryzen 5 6600U, and even rivals the high-end Ryzen 9 6900HX in multi-core performance.
