Jan 4, 4, 92 39, 1, As stated above, you can pretty much ignore the base clock speed. The turbo boost speed is what's important. As long as the CPU isn't overheating hence the need for a good fan , it will dynamically clock up to its turbo boost speeds. The base clock speed is only really relevant to the i3, celeron, and pentium CPUs, which don't get turbo boost.
The i in particular is 2. The number in the turbo column is the number of MHz increments, for the different number of cores in use. That means it can boost to 3.
And to 4 GHz when only a single core is being used. Apr 5, 1, 4 1, That looks to be a good CPU to me. A base of 2. Just get a nice HSF so that it can reach those speeds. For most gaming, money is well spent on a faster i5 than a slower i7. That's because most games are heavily dependent on single threaded execution speeds rather than parallelism. And for games that do multi-thread, I have yet to see the advantage of going with an i7 over an i5 in terms of cost justification.
Money well spent is on a fast clocked i5 with a mid-high to high-end GPU. Mar 16, , 9, , 22, Dec 12, 67 0 1, 5. Clock speed matters almost as much as core count in comparison to same architecture CPUs. It's not all that great, you need conditions that let you do this, Something as simple as motherboard supporting that functionality, then low enough temperature and enough voltage that can be supplied. While generally it means that you get temporary boost, it can also be annoying in some cases.
If you have 40 fps with turbo boost working and it decides to lower clockspeed and then ramp it up again, that can make your gameplay appear freezy. Also there are cases, when Turbo Boost will not always work, so base clock speed matters in those cases.
Basically if you want coffee lake i5, then i5 is a great choice, but if you can get i5 for almost same price, then it's rather wise to get i5 In terms of core count 6 cores are enough for many things. If you aren't sure how do CPUs compare in terms of speed, then pick one benchmark, which tests CPU's performance and get familiar with it.
I always look at Cinebench R It tends to show off maximum possible performance from processor, which not always translate into great real life task performance, but if you take it with grain of salt, it's a great tool for quick comparisons.
Jan 14, 15, 1, 78, 2, Found a comparison between i5 and i5 You can see if tiny clock speed difference makes a tiny difference on performance. Yeah, but not with a tiny price difference however. At some point the buyer just need assess where on the scale of diminishing returns they wish to stop at. Personally, I'd stick with the i and pocket the cash, or use it towards the rest of the PC build.
If later on it's not enough CPU, just upgrade and sell off the old chip. There's a reason why is more expensive by rather high margin. It's because company just makes chip with coffee lake architecture, 6 cores and let's those run at same voltage. It's much easier to achieve lower clock speed, meanwhile chips, that can reach higher clock speed are rarer. And question of OP is good, because coffee lake i5s have generally low clock speed.
So every MHz should have more impact, than one let's say 3. Jan 22, 30, 6 , 5, Nah, it's cool stuff happens. Solandri :. That is, the prices are higher due to people mistakenly thinking it's a far superior product, not due to the actual performance difference. You must log in or register to reply here.

News Comments. Instead, the Core i7 CPU can simply do much more during each clock cycle. All other things being equal, fewer clock cycles with more work are better than more clock cycles with less — fewer clock cycles means the CPU requires less power and produces less heat. In addition, modern processors also have other improvements that allow them to perform faster.
The CPU dynamically increases and decreases its speed when needed. When doing something demanding, the CPU will increase its clock rate, get the work done as quickly as possible, and get back to the slower clock rate that allows it to save more power.
The CPU may not be able to maintain top speed all the time due to overheating concerns. On the other hand, a computer with the exact same CPU but better cooling may have better, more consistent performance at top speeds if it can keep the CPU cool enough to run at those top speeds for longer. For example, most computer users will probably consider a computer with a solid-state drive faster than a computer with a traditional magnetic hard drive in normal use, even if the computer with a traditional magnetic hard drive has a CPU that performs better.
Hard disk access is a serious performance bottleneck. On the other hand, if you plan on running several virtual machines, doing 3D modeling, and playing the latest PC games, you might care more about performance. Actual benchmarks are the only really reliable way of comparing computer and CPU performance. Browse All iPhone Articles Browse All Mac Articles Do I need one?
