Hi. I had been using a Gateway dx4860 with an i5 2320 4 core processor, it was a good system and has served me for 5 years. On Sunday I bought a Lenovo H50-55 with an A10 7800 apu. I was immediately impressed with the speed of the system, it seemed to be noticeably faster than the i5. I went on line to research the CPU benchmark graphs and was surprised at the low ranking they gave the A10. I just read about how the apu structure works for compute cores so I understand why this chip is so much faster than my old i5 I am going to take this as a lesson that the benchmark scoring process is not all that accurate. Anyway thought I would throw that out.
