AMD Ryzen Threadripper 1920X vs AMD Ryzen Threadripper 2950X: Comparison
What is the difference between Ryzen Threadripper 1920X and Ryzen Threadripper 2950X?
The first real difference is boost clock: Ryzen Threadripper 1920X 4.0 GHz against Ryzen Threadripper 2950X 4.4 GHz. Add l2 cache to that, 6 MB on the Ryzen Threadripper 1920X versus 8 MB on the Ryzen Threadripper 2950X, and the pattern holds. There is a split on product family as well, Zen, Ryzen Threadripper 1000 Series on the Ryzen Threadripper 1920X versus Zen+, Ryzen Threadripper 2000 Series on the Ryzen Threadripper 2950X. They differ on release year too, 2017 on the Ryzen Threadripper 1920X versus 2018 on the Ryzen Threadripper 2950X. Core count is not the same on both, 12 cores on the Ryzen Threadripper 1920X versus 16 cores on the Ryzen Threadripper 2950X. There is a split on thread count as well, 24 threads on the Ryzen Threadripper 1920X versus 32 threads on the Ryzen Threadripper 2950X. On max memory speed there is little in it, 2667 MT/s on the Ryzen Threadripper 1920X versus 2933 MT/s on the Ryzen Threadripper 2950X. Memory support is not the same on both, DDR4-2666 on the Ryzen Threadripper 1920X versus DDR4-2933, ECC supported on the Ryzen Threadripper 2950X.
Which should you buy, Ryzen Threadripper 1920X or Ryzen Threadripper 2950X?
Take the Ryzen Threadripper 1920X for buyers wanting a mid-tier balance of core count and HEDT platform features within first-generation Threadripper. It is the wrong buy for buyers prioritizing per-core performance, later Threadripper generations offer meaningfully better single-threaded results. Take the Ryzen Threadripper 2950X for content creators and professionals wanting genuine 16-core Zen+ HEDT performance with real efficiency gains over first-generation Threadripper. It is not the one for buyers needing the highest core counts, the 2970WX and 2990WX offer more on the same platform.
What Ryzen Threadripper 1920X and Ryzen Threadripper 2950X have in common
The common ground is wider than the gap: tdp, l3 cache, memory channels, cpu socket and segment are identical here. They match on 11 further specifications as well.
Frequently asked questions
Is the SMT Support the same on the Ryzen Threadripper 1920X and Ryzen Threadripper 2950X?
It is. Both are listed at Yes, so it is not a reason to pick one over the other.
