The AMD Ryzen 5 8640U is a Hawk Level household processor unveiled this autumn, 2023. This isn’t a brand-new chip; alternatively, it is a rebadged Ryzen 5 7640U that we’re coping with right here. Identical to the 7640U, the R5 8640U has 6 SMT-enabled cores (12 threads) working at 3.5 GHz to 4.9 GHz. These Zen 4 structure cores are mated to the Radeon 760M built-in graphics adapter.
Moreover, this Ryzen 5 collection laptop computer chip comes with the 2nd-era Ryzen AI know-how.
AMD Ryzen 5 8640U Processor Structure & Options
The Zen 4 structure powers Hawk Level household chips, similar to Phoenix and Dragon Vary. That is not to say there isn’t any distinction between the three. With Hawk Level, AMD is betting massively on generative AI; these chips are stated to ship an improvement of as much as 40% in generative AI efficiency over 7040 collection APUs, making apps like DaVinci Resolve and Adobe Photoshop much more highly effective.
Unlike Zen 3, Zen 4 options AVX512 assist and, due to many different enhancements with bigger caches/registers/buffers, is slated to deliver a double-digit IPC enhancement over the previous.
Elsewhere, the AMD Ryzen 5 8640U has 16 MB of L3 cache and USB 4 assist (subsequently, Thunderbolt is supported nicely). The chip is suitable with DDR5-5600 and LPDDR5x-7500 RAM, which continues to be spectacular as of H2 2023.
A system powered by this Ryzen 5 could have entry to twenty PCIe 4 lanes; this implies a speedy sufficient NVMe SSD capable of shipping speeds as much as 7.8 GB/s.
Techniques powered by this APU are anticipated to run 64-bit Home Windows 11, 64-bit Home Windows 10, or Linux. Like most laptop computer chips, the AMD Ryzen 5 8640U is both overclockable and user-replaceable. It will get soldered down for good (FP7, FP7r2, FP8 socket interfaces).
AMD Ryzen 5 8640U Performance
It is secure to count on the chip to be a minimum of 10% quicker than the Zen 3 Plus-powered Ryzen 5 6600U (6 cores, 12 threads, as much as 4.5 GHz).
Your mileage could fluctuate depending on how excessive the CPU energy limits are and how competent the cooling capability of your laptop computer is.
AMD Ryzen 5 8640U Graphics
The Radeon 760M has 8 CUs (512 shaders) working at as much as 2,600 MHz. While it is not nice for gaming (except you might be fantastic with resolutions akin to 900p and low-element settings), the iGPU will allow you to use as many as four displays with resolutions as excessive as SUHD 4320p. Additionally, HW-decodes and HW-encodes are the most broadly used video codecs with AV1, HEVC, and AVC without breaking a sweat.
Energy consumption
The AMD Ryzen 5 8640U has a long-term energy restriction (default TDP) of 28 W that laptop computer makers are free to vary to something between 15 W and 30 W. Both methods, a lively cooling answer, are a must for any system powered by the chip.
Finally, but not least, the 8640U is manufactured on TSMC’s 4 nm course for prime, as of late 2023, vitality effectivity.
