Heat dissipation is a limiting factor and larger chips require higher voltages. Which would require a even lower clock rate.

- michaelt 13y agoLet's say the NSA's chip fab is 10 years out of date - the same technologies as an Athlon XP "3000+" 2.1 GHz CPU with a 70 watt TDP. Worked just fine in a lot of consumer desktop PCs. If they needed a lower TDP, couldn't they just drop the clock rate and use wider features for lower gate leakage?
- DannyBee 13y agoAgreed. It's also likely the case that in practice, their TDP doesn't matter. Yes, they have a budget, but somehow i think their main problem is more finding sources of electricity and cooling, not paying for it.
