Speaking of the current Ryzen 5000 series, the desktop CPU is the Vermeer series with the Zen 3 architecture, but the Ryzen 5000 series laptop APUs are mixed with the improved Zen 2 architecture (Lucienne) versions. and the new Zen 3 (Cezanne). Accordingly, the Ryzen 5000 series with odd tails will use Zen 2 and even Zen 3 like:
Lucienne (Zen 2)
- Ryzen 3 5300U 4/8, 2.6 – 3.85 GHz, 4 MB L3 Cache
- Ryzen 5 5500U 6/12, 2.1 – 4 GHz, 8 MB L3 Cache
- Ryzen 7 5700U 8/16, 1.8 – 4.3 GHz, 8 MB L3 Cache
Cezanne (Zen 3)
- Ryzen 3 5400U 4/8, 2.6 – 4 GHz, 8 MB L3 Cache
- Ryzen 5 5600U 6/12, 2.3 – 4.2 GHz, 12 MB L3 Cache
- Ryzen 7 5800U 8/16, 2 – 4.4 GHz, 16 MB L3 Cache
While all these variants feature a 10 – 25 W TDP, manufactured on TSMC’s 7nm process, the Zen3 architecture can be seen for significantly higher clock speeds and with a new CCD layout with 8 cores / CCX. AMD could also design a larger L3 buffer, as evidenced by the Ryzen 3 5400U with 8 MB of the buffer, double the Ryzen 3 5300U.
However, compared to the Ryzen 4000U (Renoir) line on current AMD laptops, the direct replacement Ryzen 5000U versions opened hyperthreading. For example, the Ryzen 7 5700U replaces the Ryzen 7 4700U which has 16 threads instead of 8 as before.
Going with the Ryzen 7 5700U is a Radeon RX Vega 8 GPU with 8 CU, 512 Stream cores, 1900 MHz clock, an upgrade over Ryzen 7 4700U’s RX Vega 7.
As for the Acer Aspire A515, besides the new APU, it has 8 GB of DDR4 RAM, which can be upgraded up to 24 GB and so this 8 GB of RAM is soldered on the board, has 1 SO-DIMM slot to upgrade with dark 16 GB multi-bar. SSD has a capacity of 512 GB. This machine is in the popular segment, the size is 15.6 “, FHD screen with IPS panel.
The machine has 4 USB-A ports including 2 USB 3.1 Gen1 (5 Gbps) ports and 2 USB 2.0 ports, 1 USB-C supports USB 3.1 Gen2 (10 Gbps), HDMI and RJ-45 LAN connection next to the Wi-Fi 6. 48 Wh battery capacity and weight of only 1.9 kg.
