Intel Celeron Dual-Core microprocessor

Celeron Dual-Core E1200 is a dual-core version of Celeron 420. Both processors are based on a Core micro-architecture, have the same core and front-side bus frequency, and the same size of L1 and L2 caches. Having one extra core, the E1200 outperforms the Celeron 420 in multi-threaded applications (in some well-designed applications by almost 100%), and, thanks to L2 cache shared between two cores, the E1200 can perform as fast as the Celeron 420 in single-threaded applications.

Having only 512 KB of level 2 cache, the Celeron E1200 processor performs 5% - 10% slower in business applications than the Pentium Dual-Core E2140, or up to 15% slower in games and other memory-intensive applications.
