New HUDIMM DDR5 Standard Promises Cheaper Memory, But Testing Shows It Slashes Bandwidth in Half
Wccftech • • technology
Key Points:
- Intel and partners have introduced a new DDR5 memory standard called HUDIMM, which reduces the memory channels from two 32-bit channels to one 32-bit channel to lower costs by populating half the banks on a module.
- HUDIMM modules will be available in 8 GB and 12 GB sizes, allowing users to mix and match with standard UDIMM kits, targeting budget-conscious PC builders.
- Performance tests show a significant drop in bandwidth with HUDIMM compared to standard UDIMM, with single-channel HUDIMM bandwidth roughly half that of dual-channel UDIMM, while latency remains similar.
- The reduced performance means that HUDIMM modules, despite their lower cost, may underperform even compared to DDR4 memory or single UDIMM modules in single-channel mode, raising concerns about their value proposition.
- It remains unclear if HUDIMM modules will be priced proportionally lower to justify the substantial performance trade-offs, which could impact their adoption among gamers and PC builders.
