I want to upgrade the CPU of an old computer I have(CPU in it being an Intel Core2 Duo E8400 3.0Ghz). I’ve looked in the motherboard manual to see wich CPU are compatible with it. Since there’s is a few options I’ve looked the benchmark of some of them on the passmark website. The current CPU installed in the computer is a 3.0 Ghz dual core and has an average CPU mark of 2154.
I’ve looked 2 options for the upgrade:
Intel Core2 Quad Q9300 2.5Ghz quad core with an average benchmark of 3163 (CPU released in Q4 2008)
Intel Core2 Quad Q8400 2.66Ghz quad core with an average benchmark of 3176 (CPU released in Q4 2009)
Of course the second option seems better than the first one, but I’m still worrying about the Ghz, since the current CPU installed in the computer is 3.0Ghz and these 2 options have lower Ghz than the current installed one,but more core.
I want to have higher computer performance, so should worry about the lower Ghz, or it doesnt matter since they both have more cores?
First, sadly this question should be closed because the choices are too broad and too opinion based. That said, without knowing what you want to do or what your motherboard can handle, CPU speed is silly at best. Tons of other factors affect speed on modern systems and it is utterly all dependent on purpose of the system and what you expect it to do. My recommendation is get the best upgrade you can afford. Don’t penny pinch if you care about the system. But again, who knows if your current CPU is fine for your purposes and something else—like storage—should be upgraded. – JakeGould – 2018-07-14T23:56:20.087
This is a 10 year old system so you can look at the benchmarks and get a very good idea of the relative capabilities. You will not notice any difference between those two upgrades but either will be significantly better than what you have. I don't see how this is being seen as an opinion by some. The fact that going from HDD to SDD will be a bigger system speed improvement is only a distraction because it isn't what is being asked. – krowe – 2018-07-15T00:02:36.030
You might get better answers if you provide more information - like CPU model numbers and system purpose. – davidgo – 2018-07-15T00:04:24.847
@JakeGould ive checked in the motherboard manual to check only cpus who are compatible according to the manual. The hard drive of that computer has been replaced about 1 year ago for a standard SATA III 5400rpm one so I dont think the hard drive is really causing problems here. I updated my post with CPUs brands and models if that can help – William Weifenbach – 2018-07-15T00:35:56.473
@davidgo updated the post with CPUs models and brands name – William Weifenbach – 2018-07-15T00:38:46.280
@krowe ive updated my questions with cpus models and brands names if that can help – William Weifenbach – 2018-07-15T00:43:03.583
@WilliamWeifenbach Unfortunately, this is all still very opinion based. Besides, while you replaced the hard disk, I believe an SSD would improve things. Two understand my perspective, I work daily on a mac Mini (2012) and a MacBook Air (2013) and the MacBook Air has worse CPU specs than the mini but it’s noticeably faster. And my mac Mini turned into a faster machine when I upgraded the hard disk to an SSD. It really all depends on personal use. – JakeGould – 2018-07-15T00:46:19.743
