Clock speed and multipliers
Clock speed and multipliers
It seems your Athlon X4 860K OC'd to 4.2GHz has a higher multiplier (42x) compared to your friend's FX-6300 at 3.8GHz with a lower multiplier (19x). The difference in performance might be due to various factors such as architecture, cache, or system configuration.
It could relate to the base clock speed of the base clock and the front side bus. I'm not confident about my AMD details these days, but Intel CPUs function roughly the same way: base clock/FSB multiplied by a CPU multiplier. For example, 100mhz base clock times a 37 multiplier equals around 3700mhz or 3.7ghz. I think Intel likely adjusts its base clock and uses a lower multiplier on the 6300.
It could relate to the base clock speed of the base clock and the front side bus. I'm not confident about my AMD details these days, but Intel CPUs function somewhat similarly: a base clock combined with a CPU multiplier results in a higher speed. I think Intel likely adjusts its base clock and uses a lower multiplier on the 6300.
it might relate to the pace of the base clock. I don’t have much confidence in my AMD details these days, but Intel CPUs operate this way: base clock (100mhz) multiplied by a factor (37 here) equals around 3700mhz or roughly 3.7ghz. You’re completely correct.
The 860k model has a base clock speed of 100, while the FX 6300 runs at 200. That gives a total of 19 times 200, which is about 3.8ghz. You can find this information in CPU-z.

the explanation might relate to the base clock speed and front side bus. I don’t have much detail on my AMD specs lately, but Intel CPUs function roughly the same: a base clock paired with a multiplier (like 37) to reach the final frequency. I think Intel likely adjusts its base clock and multiplier differently on models like the 6300. Thanks for clarifying this.

the point is likely connected to the base clock rate. I’m not confident with my AMD data now, but Intel CPUs operate similarly: base clock (100mhz) multiplied by a multiplier (37) gives around 3700mhz or 3.7ghz.
The 860k model uses a base clock of 100 and the FX 6300 has a base clock of 200, resulting in roughly 3.8ghz.
You’re correct, and this makes sense.
I had to go with the detailed one though.
