Prefill is compute-bound, decode is memory-bandwidth-bound. Why splitting inference into two purpose-fit GPU pools beats one uniform fleet.
Tag: Memory Bandwidth
The v5 generation can be told as a cores-and-clocks story, but a significant change is bandwidth: the private fabric doubled to 40 Gbps, memory moved to DDR5-6400, and the lane budget grew to 88 PCIe 5.0 lanes.
This configuration is no longer in the OpenMetal catalog. The XL v4 High Frequency was a high-clock variant we no longer stock or offer. The specifications below remain accurate for
Q: How does DDR5-5200 memory on the XL v4 High Frequency compare to DDR5-4800 on the standard XL v4? DDR5-5200 on the XL v4 High Frequency provides approximately 8% higher
