The rest of the specifications are identical and largely uninspiring. We're looking at 4800MHz DDR5 memory modules with 4800MHz frequency, CL40 timings, and operating voltage of 1.1V. So far, all of the first DDR5 memory modules have CL40 timings, which is very loose.
The DDR5 technology will not only improve the frequencies and bandwidth but will also provide a power efficiency upgrade by offering lower voltage by default. The DDR5 modules will also feature onboard power controllers, which will further improve overclocking potential. Multiple memory modules manufacturers have already announced that they are developing kits with frequencies from 6400 MHz up to even 10 GHz. However, those are expected at a later time.
The first DDR5 capable platforms are expected towards the end of this year. Intel's Alder Lake-S is expected to support DDR5-4800. AMD is expected to support DDR5 via its future Zen 4.
