Gaming performance

Let's see how good Celeron B830 and Atom E3845 are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Celeron B830

0.3% faster in synthetic tests
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)
x86-64 (a general name for 64-bit extension of x86 instruction set. There are AMD64 and Intel 64 versions that differ very little)
