DDR3 1600 RAM operates at a 1600 MHz clock speed, achieving a peak data transfer rate of 12,800 MB/s (or 12.8 GB/s), known as PC3-12800, by performing 1.6 billion transfers per second, making it a fast standard for DDR3 systems, though not the absolute fastest possible.
In general it is good enough and it actually is the fastest kind of memory supported on locked Intel motherboards before socket 1151. Though if you have a Z87/Z97 motherboard and unlocked K cpu, then getting memory faster than 1600MHz can be beneficial.
Yes -- 16 GB of DDR3 RAM was and remains sufficient for the vast majority of PC games in 2020, with caveats. Gaming requirements: Most AAA titles released around 2020 list 8--16 GB as recommended RAM. 16 GB covers the game itself plus the operating system and common background processes with comfortable headroom.
The clock speed of DDR3 vary from 800 MHz to 2133 MHz, where 2133 MHz is the its peak in some cases, generally clock speed is vary between 1600 to 1800 MHz.
The DigiTimes insider network proposes that the big three: "may phase out DDR3 and DDR4 by 2025...by the end of 2025... anticipating a future focused on advanced memory technologies." Older standards are falling out of favor, with DDR5 and high-bandwidth memory (HBM) on the ascent.

DDR3 is not used on modern systems. It started getting phased out back in 2015 when Intel launched their Skylake CPUs that used DDR4. Even DDR4 is on its way out now, DDR5 is the memory standard used on most current systems.
DDR4 boasts faster transfer rates in comparison to DDR3, commencing at 1600 MT/s. This starting speed is twice that of DDR3, and planned bandwidth increases could propel it well beyond 25600 MB/s. DDR4 exhibits greater efficiency by consuming up to 40% less power and requiring only 1.2V per RAM module.
At maximum resolution and the best graphics settings, the game along with the system occupies almost 9 GB of RAM. A good reserve of RAM is necessary for the normal operation of the computer. So, if you plan to play in UHD quality, you need 16 GB of RAM.
Here are a few circumstances that may make it less suitable for modern computing needs: Lower Speed and Bandwidth: Compared to DDR4 and DDR5, DDR3 has significantly lower data transfer rates and bandwidth, which can affect performance in demanding applications like gaming, video editing, and high-performance computing.
System Compatibility: DDR3 and DDR4 are not interchangeable due to different pin configurations, so you'll need a motherboard that specifically supports DDR4. Upgrading will likely require a new motherboard and, in many cases, a compatible CPU, as older processors may not support DDR4.
Signs It Might Be Time for More RAM
For light users, students, or those on a very tight budget: Yes, 8GB is still a manageable, entry-level option for basic tasks. For everyone else—especially gamers, creators, and anyone who wants a frustration-free, future-proof PC: No. You should consider 16GB the absolute minimum for a new machine in 2025.
No worries, 3200 MHz RAM shows up as "1600 MHz" (half the RAM's speed) because what you see is the RAM's clock speed at half the speed, hence it is showing as 1600 MHz, but the actual RAM's bandwidth is doubled (DDR = Double Data Rate) and thus the effective RAM speed is 3200 MHz. Stick with the 3200 MHz RAM.
some games would run but i think you'd experience a bottleneck. DDR3 was my favorite era. Depends what you want to use it for. Older games or esports titles should be mostly fine.
4th gen was the last generation to use ddr3 widespread. There are some 6th/7th gen motherboards that use ddr3, but there aren't very many of them, so I'd consider 4th gen to be the last time that ddr3 was used for the most part.
DDR3 modules can transfer data at a rate of 800–2133 MT/s using both rising and falling edges of a 400–1066 MHz I/O clock. This is twice DDR2's data transfer rates (400–1066 MT/s using a 200–533 MHz I/O clock) and four times the rate of DDR (200–400 MT/s using a 100–200 MHz I/O clock).

With DDR3, you can only get 16GB DIMMs as load-reduced, buffered and fully-buffered modules. As asoroka already mentioned, these are server-oriented variants that won't work on mainstream and even HEDT Intel CPUs.
If you're upgrading an older PC, DDR3 RAM might be your only option, but it's not ideal for modern gaming. For most gamers, DDR4 RAM provides excellent performance and value. But if you want cutting-edge speed and are building a new high-end system, DDR5 RAM is the way to go.
