However, what the SPECint_rate and SPECfp_rate benchmarks don't show is the ability to handle process-to-process throughput rates. Kanter highlights this to DailyTech, stating, "For stuff like web serving, application serving, I think Barcelona will kinda be a mixed bag, won't be a real home run." He clarifies this by emphasizing many of the K10 changes have possible drawbacks, including the split power-plane.
"The split power-plane, while saving power, has tendencies to make moving data between them a little awkward." Kanter continues, "It's a subtle thing, but in the end it will all depend on latency."
