Core2Duo vs Pentium Dual-Core ???

Hey everyone,

whats really the difference between the core2duo and a pentium dual core processor?

also which would be better for gaming and overclocking?

  1. At the same clocks the core 2 duo is faster! The pentiums have smaller L2 cache but there are so many versions you would have to pick the two processors in question to compare them.
  2. okay then the Core2Duo E6700 and the Pentium Dual Core E6700?

    aside from the L2 Cache i dont see any difference?

    also, what exactly does the L2 Cache do in reference to performance?
  3. The Pentium CPUs are currently the "value" line of Intel's CPUs.

    The former value oriented CPUs were the Celerons (celery) when the Pentium name was used for the performance and mainstream CPUs.
  4. L2 Cache is used to store instructions for the CPU to process. It sits in the CPU itself and it has low latency; meaning it is fast.

    Instructions that cannot fit into the L2 Cache is stored in the system RAM which is much slower than the L2 Cache. It means the CPU takes a little longer to process because it has to wait to receive the instructions from RAM to the L2 Cache and finally to the CPU.
  5. Core2duo E6700 http://ark.intel.com/Product.aspx?id=27251
    Pentium E6700 http://ark.intel.com/Product.aspx?id=42809&processor=E6700&spec-codes=SLGUF
    Comparing those two the pentium makes up for the lack of L2 Cache with 3.2 GHz over the 2.66GHz on the Core2duo.
  6. now in reference to L2, is that 1 or 2mb extra, that a comparable core2 might have, enough that i will actually see some sort of performance increase?
  7. also, i heard from a few places that the pentium is much better at running higher clock speeds more stable on air than a core 2?

    Between the two E6700 that is correct the Pentium is the better it has 20,3 % higher core clock! If you had a core2duo that ran the same speed as the pentium it would be faster!
    Here you can compare c2d E7500 and pentium E6500 that run the same clock, http://www.tomshardware.com/charts/desktop-cpu-charts-2010/compare,2433.html?prod[4429]=on&prod[4434]=on
  9. i guess that confirms the theory that the pentiums overclock much better then the C2D's!!
