Lenovo ThinkSystem SR685a V3
Lenovo's 8U AMD accelerator server, and the machine Lenovo builds around the Instinct MI300X. Two AMD EPYC processors, either 5th generation 9005 Turin or 4th generation 9004 Genoa, reach 128 cores at up to 400 W and are paired with up to 3 TB of host DDR5 across 24 DIMMs. The accelerators arrive as one factory-integrated 750 W eight-GPU board rather than as separate modules, ordered under feature code C1HK. Power is eight hot-swap supplies in full N+N redundancy, all standard rather than optional, and the chassis measures 447 by 351 by 924 mm at up to 109.4 kg. Lenovo publishes no system power draw, no accelerator memory total and no system-level throughput; its guide gives per-GPU figures only. Worth noting that Lenovo's earlier datasheet for this model number describes an HGX H200 machine, while the current product guide describes this MI300X configuration; the guide is the source used here.

Frequently asked questions
How much does the ThinkSystem SR685a V3 cost?
Lenovo sells the ThinkSystem SR685a V3 on quote through OEMs and resellers, and nobody rents a whole one by the hour. Renting its 8 Instinct MI300X accelerators separately at the cheapest live rate Flopper tracks, $2.39 per GPU-hour across 5 providers, comes to about $19.12 an hour for the equivalent capacity.

How much power does the ThinkSystem SR685a V3 require?
Lenovo has not published a power figure for the ThinkSystem SR685a V3, and Flopper does not derive one from the accelerator count because the rest of the system draws power too.
How many GPUs are in the ThinkSystem SR685a V3?
8. The ThinkSystem SR685a V3 carries 8 AMD Instinct MI300X 192GB accelerators in a rack form factor, and every throughput figure on this page is the total across them. Instinct MI300X specifications →
