| 1320939 | 2013-01-01 03:35:00 | The title says it all. How much difference does a 1.8 ghz upgrade to 2.5 ghz make? Same specs otherwise for use at school so maybe some 3D work and a little code compiling and website creation Thanks in advance |

| 1320940 | 2013-01-01 03:52:00 | Is this a overclock? Or a cpu upgrade? By itself a .7ghz difference would be noticeable, combined with a faster, newer cpu it would definitely make a difference. | Nick G (16709) | ||
| 1320941 | 2013-01-01 04:00:00 | Guess it somewhat depends on the cost of the upgrade. For the same cost, you would take 2.5 without doubt. Most of the time the cpu is waiting for disk or input but for 3D rendering, for example, the higher speed would cut time off the job. Maybe 10 min off an hour's job? All very subjective, though. But some rendering programs can use the GPU so all bets are off! Not much help but there really is no simple answer. |

| 1320942 | 2013-01-01 04:02:00 | No, just comparing different models of computer but other than the cpu difference they are the same. Both i5 just different values. Would there be a noticeable difference if compared side by side? Thanks |

| 1320943 | 2013-01-01 04:20:00 | Yes especially if the higher clocked one has more cores. But weter or not its worth it really depends on what you use your computer for. |

| 1320944 | 2013-01-01 12:49:00 | Maybe of a similar question for this topic If both Cpu are the same speed what difference does it make if the motherboard is of Sandy Bridge VS ivy bridge? |

| 1320945 | 2013-01-01 13:13:00 | None really.... And its the cpu that is sandy or ivy bridge. | Slankydudl (16687) | ||
| 1320946 | 2013-01-01 19:33:00 | Maybe of a similar question for this topic If both Cpu are the same speed what difference does it make if the motherboard is of Sandy Bridge VS ivy bridge? The motherboard is neither, it is the CPU which is. Ive bridge CPU's a newer, so more energy efficient and probably a bit faster. They also have better integrated graphics which is an important point to not if you are not using a dedicated graphics card. |

| 1320947 | 2013-01-02 01:02:00 | These days it is near on impossible to compare CPUs simply on the clock rate. The performance will vary depending on the number of cores, how much cache there is, how the cache is shared between the cores, ...... etc. The best you might be able to do is find a bench mark test between the two CPUs in question. | johnd (85) | ||
| 1320948 | 2013-01-02 18:49:00 | When they are both the same series then an approximate 30% difference in clock speed does translate to an approximate 30% in CPU performance. But as mentioned it will only be noticeable in those applications that can utilise 100% of the CPU power. In general usage it will feel pretty much the same. Ivy bridge is a little faster clock for clock than sandybridge and uses less power, the only advantage to sandybridge is a slightly better amount of headroom when overclocking. Ivybridge seems to hit a wall where the heat output and voltage requirements for overclocking goes up dramatically whereas sandybridge seems a bit more linear. The result is the maximum overclock of ivy tends to be lower but the improved per clock performance makes up for that meaning a maxed out 2500K or 3570K perform much the same. If you are buying new there is no reason to still buy sandybridge, but nothing wrong with them if you do. |
