See our hub page on the Renoir Processors for more information. Furthermore, 8 MB level 3 cache can be found on the chip. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics card with 6 CUs and up to 1500 MHz?. Therefore, the Ryzen 5 4680U is a very fast 15 Watt CPU and clearly faster than the old Ryzen 7 3700U. Thanks to the 4 GHz Boost clock, the single core performance should be similar. However, it should still beat the fastest 15 Watt Ice Lake Intel Core i7-1065G7 (4 cores, 3.9 GHz). With two less cores, the Ryzen 5 4600U is clearly slower than the Ryzen 7 4980U in multi threaded workloads. Compared to the older Ryzen 5 4600U, the 4680U seems identical. The chip is manufactured in the modern 7 nm process at TSMC and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips. They are clocked at 2.1 (guaranteed base clock) to 4 GHz (Turbo) with SMT / Hyperthreading support (12 threads).

The 4680U integrates six cores based on the Zen 2 microarchitecture. The AMD Ryzen 5 4680U is a processor for thin and light laptops based on the Renoir architecture. The Apple M1 includes 16 billion transistors (up from the 10 billion of the A12Z Bionic and therefore double the amount of a Tiger Lake-U chip like the i7-1185G7) and is manufactured in 5nm at TSMC.ĪMD Ryzen 5 4680U ► remove from comparison Apple claims that it is faster than any other iGPU at the time of announcement.įurthermore, the SoC integrates a fast 16 core neural engine with a peak performance of 11 TOPS (for AI hardware acceleration), a secure enclave (e.g., for encryption), a unified memory architecture, Thunderbolt / USB 4 controller, an ISP, and media de- and encoders. The integrated graphics card in the M1 offers 8 cores (7 cores in the entry MacBook Air) and a peak performance of 2.6 teraflops. Those should offer a better-sustained performance according to Apple.

The M1 is available in two TDP variants, a passive cooled 10 Watt variant for the MacBook Air and an active cooled faster variant for the MacBook Pro 13 and Mac Mini. The efficiency cores (E cluster) clock with 600 - 2064 MHz, the performance cores (P cluster) with 600 - 3204 MHz. The four efficiency cores are a lot smaller and offer only 128 KB instruction cache, 64 KB data cache, and 4 MB shared cache. According to Apple the performance of these cores should be better than anything on the market (in late 2020). The big cores offer 192 KB instruction cache, 128 KB data cache, and 12 MB shared L2 cache. It offers 8 cores divided in four performance cores and four power-efficiency cores. The Apple M1 is a System on a Chip (SoC) from Apple that is found in the late 2020 MacBook Air, MacBook Pro 13, and Mac Mini.
