GoKawiilBlizzard reveals WoW: Forever ran on 70,480 CPU cores and 251TB of RAM
Blizzard disclosed that World of Warcraft: Forever's launch infrastructure used 3,924 virtual machines spread across 70,480 CPU cores and 251,136GB of memory. That works out to roughly 18 cores and 64GB per virtual machine, and the launch has been widely praised as one of the smoothest in the franchise's history.
GoKawiil's interpretation of the reporting above, not reported fact.
The figures show how Blizzard shifted its scaling strategy since 2009, when WoW ran on 75,000 cores but only 112.5TB of memory across 10 data centers; the new setup has fewer cores but more than double the memory, suggesting memory capacity and bandwidth, not raw core count, is now the key bottleneck for massive online launches. The numbers also illustrate how much cloud infrastructure costs have grown for live-service games expected to handle huge concurrent player spikes without crashing.
- WoW: Forever's launch used 3,924 virtual machines, 70,480 CPU cores, and 251TB of RAM.
- Compared to 2009's WoW infrastructure, core count dropped 6% but memory more than doubled.
- The scale is roughly equivalent to thousands of high-end gaming PCs or hundreds of modern server nodes.
