Report R5 · Benchmark report (official edition, No. -004)
This report answers whether an external KV tier can stand in for GPU memory. A seven-way comparison on a 14B model (GDS direct read, recompute at two HBM sizes, direct read with low HBM) builds a three-step argument for HBM equivalence. The platform is a single MetaX N260 GPU; the method carries across platforms, but the numbers are never mixed with MI308X results.
128 GB
MetaX N260 single GPU, 14B model, seven-way comparison
Conclusion of a seven-way comparison on a 14B model: an external KV tier can stand in for 128 GB-class HBM residency. That campaign ran on a single MetaX N260 GPU; the method carries across platforms, the numbers are not mixed with MI308X results.

Test jointly first, decide afterwards
Every engagement starts with a gated joint test of about 10 weeks. Four gates are passed in sequence; if one is missed, the project stops there, so you never pay for a benefit that was not demonstrated.
