249.6 GB/s of bandwidth.
This week, two memory makers — G.Skill and v-color — formally announced their quad-channel memory module kits for AMD Ryzen Threadripper 7000-series processors. The new ECC-enabled RDIMM kits with AMD EXPO profiles are factory-overclocked and top at 6400 MT/s and 7200 MT/s speed bins. But apparently, there are more advanced memory modules (up to 7800 MT/s) for Threadrippers coming from more companies, according to a Gigabyte listing.
In addition to G.Skill and v-color, Kingston is prepping its quad-channel 64GB and 32GB kits rated for DDR5-6000 CL32 at 1.35V and DDR5-6400 CL32 1.4V speed bins for AMD’s latest Ryzen Threadripper 7000-series platform that targets both enthusiasts with deep pockets as well as professional-grade workstations. Gigabyte lists these modules alongside its TRX50 platform, so the company primarily positions its kits for the enthusiast-grade quad-channel Ryzen Threadripper 7000 builds.
Perhaps more interesting is that v-color is prepping a lineup of ultra-fast ECC-enabled quad-channel RDIMMs for AMD’s latest Threadrippers with ECC profiles. For those who are fine with moderate performance and stock speeds, v-color will offer DDR5-4800 and DDR5-5200 kits. But for more extreme enthusiasts who want to get every last bit of performance from their TRX50 rigs with Ryzen Threadripper 7000-series CPUs, v-color will offer kits rated for up to DDR5-7800. To provide some context, a quad-channel DDR5-7800 memory subsystem provides a memory bandwidth of 249.6 GB/s.
It is noteworthy that G.Skill, which specializes in high-performance memory modules, tops its overclockable RDIMM offerings with AMD EXPO aimed at Ryzen Threadripper 7000-based systems at 6400 MT/s and equips them with label heat spreaders.
By contrast, v-color goes above and beyond with 7200 MT/s, 7600 MT/s, and 7800 MT/s. To ensure that its modules do not overheat, it equips them with rather serious heat spreaders akin to those used on some server-grade RDIMMs.
When it comes to pricing, factory-overclocked RDIMMs are certainly considerably more expensive than regular performance-enhanced memory modules. G.Skill’s Zeta R5 Neo 64 GB kit costs $530, whereas the 128GB kit is priced at $1,070.
