performance if upgrade i5 to i7 for my x230
Some will argue otherwise but I don't think you'll notice it enough to attempt to source an i7 over an i5 if the cost or rarity is too much
I had a x230 i5 and i7. There is zero noticeable difference in performance in basic computer functions such as video streaming and surfing the web. The i5 has better battery life than the i7 in my opinion.
First 2 CPUs are stock, as you can see, performance boost is quite small.
Last one is aftermarket modification that requires desolder CPU and solder another one in its place and requires specialized equipment. You can of course buy already modified motherboards
Can't find significant difference.
But, if you upgrade frome HDD to SSD, there will much different between.
tested both i7 3632 and i7 3840 on my t430 i5 3320, speed is quite the same if you use pc with daily software
If you mean web browsing with bad connection then yeah, but because most of the time you're waiting for IO. Otherwise, 4 core CPUs outclass any 2 core anytime since load is distributed among them. That's why even single-process applications benefit from more CPU cores.
Basically what he's getting at is having more workers share the same workload accordingly being more efficient or less taxing overall than if you were to have the same workload across less workers
You can think of it as having 4 librarians stacking shelves from a single box of unorganized books, compared to having 2 librarians stacking shelves from the same box
It's called parallel processing, and it can only be used for a few types of applications, and only for code that's written to take advantage of the technique.
maybe I should rephrase it, by load I mean everything that is going on on your desktop all at once, having more cores would lessen the load of running your OS and the apps on it overall
Sorry about delay. Yes, you can't run single process application on multiple cores. Such process will always occupy single CPU thread.
But hell of a lot of processes are running concurrently at any given time. Just look at windows task managers. THOSE are distributed among other CPU threads so main thread has more free time to do whatever needs to be done
Write down use cases. Portability and getting things done? T480s. 4 core 8 threads CPU, decent performance, though you will hit crippling thermal throttling (from 4GHz turbo boost to 1.8GHz base clock) the moment you try to run any demanding task(e.g. compile C++ project).
Extreme portability? Anything from X series. Though X280 might be more pricey with same CPU as T480s. Office use vs. travelling manager use cases.
If you need cheap but solid workhorse, you might try T460p, T470p or even P5x series. Be warned though-while my company issued P53 packs quite a punch-6 core 12 threads 9th gen high performance i7-i don't want to carry it all day in backpack.
Honestly I don't see the big difference between x201 i5 and x230 i5 3.5 GHz
Yes maybe if I would do something more graphical cpu loading stuff, than there will be difference. But day to day of regular use (browsing, office, YouTube, 2D games) no issue at all.
Can't do xD besides it's more less the same as they had "fake" dual core i7 so it was more like i3 than i7
