Gaming performance

Let's see how good Celeron B840 and Core i3-2340UE are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Celeron B840

Cheaper ($86 vs $250)
Idle States (a set of CPU idle states of varied depth, used for energy saving purposes)
Enhanced SpeedStep (saves energy by managing CPU frequency and voltage in realtime. Supercedes SpeedStep)
Thermal Monitoring (prevents a CPU from overheating by lowering frequency upon reaching the critical temperature)
Execute Disable Bit (allows marking some memory ranges as non-executable, thus protecting software against so-called "buffer overflow" attacks)

Advantages of Intel Core i3-2340UE

Less power hungry (17 vs 35 watts)
AVX (Advanced Vector Extensions - a set of SIMD instructions working with 128- and 256-bit registers)
