I think you mean 128KB and 512KBNo Semprons have 128MB of L1, No Semprons have 1MB or 512MB of L2!!
The older Celeron D's only had 256K, but the new 65nm models have 512KB.Not all celeron D have 256KB cache
Some of them have 512KB cache like this one

All in all, the Sempron would be better if your more focused on gaming, but if you dont do much gaming, the newer Celerons would be the best overall.
