There are more parameters when comparing and choosing CPUs.
Also lets not forget that performance depends on what we do.
Lets bring list of parameters which can affect performance (sorted by importance, high to low).
CPU frequency - how many GHz. The most important parameter. The more, the better.
Core/Thread count - (another very important ...
The advantages of using water cooling over air cooling include water's higher specific heat capacity, density, and thermal conductivity. This allows water to transmit heat over greater distances with much less volumetric flow and reduced temperature difference.
For cooling CPU cores in computing equipment, the primary advantage of water ...
The most obvious way is just to simply benchmark the two against each other. If you have a machine with each processor installed, or one machine with the ability to change the processor, then you can run tests. One machine would be better, to preserve all the other contributing aspects.
Perform some common tasks with each processor installed. These should ...
General guidance for buying cameras alone can be applied here. There are several important aspects:
This is the resolution that the image sensor is capable of capturing. The greater the number, the more detail you'll get in your image. This does, however, combine with the next point:
The bigger the sensor, the bigger the pixels can be. ...
Water-cooling is better than traditional fan-cooling.
Using it is reasonable if you have hardware that gets hot very often and reaches its temperature limits; and you can't cool it down in traditional ways. Another (bad) reason is something like "hey people look, I have watercooling because its cool". And the last reason is - it's not noisy and dusty.
I'm going to divide water cooling into two categories: Closed loop and Open loop. Now we can compare Tower (air), CLC, Open loop and exotic (LN2 or similar) cooling methods.
Big air coolers are generally around the $50-80 mark and produce decent performance for the 50-150W CPUs that you see in everyday life. Pretty heavy, and mounted on the motherboard, in ...
I've got the 256gb variant of the Samsung 850 Pro and running a few tests would be quite enlightening. Improving compile time may also depend on processor so... it depends on your options. Likewise with IDE & Git performance. That said, I upgraded from an 840 (which I can't find the benchmarks for, its on my laptop at the moment) and it was a significant ...
The general list of features you should consider has been pretty well covered by others, I will tackle this from a slightly different angle:
Just how important is the camera to you?
Is it more or less important than the phone features, or the phone OS for example? There are options that prioritize the camera over the phone, like the Samsung Galaxy S4 Zoom. ...
It depends mainly on the type of NAND the SSD uses, and also somewhat on the controller.
Higher quality SLC NAND stores one bit per cell. This make the cells much faster and longer lived, whereas MLC and TLC (2 bits and 3 bits) degrade more easily and are harder to read and write, especially write. Since the MLC SSDs are more common, most SSDs do have slow ...
Please note, this is answer is for the Dell Inspiron 15-5558, which hopefully is the same as the OP has.
Is my laptop compatible to upgrade to SSD ?
Yes, as you can see in the following picture, the drive positioning was clearly designed to make the drive easily replacable.

What dimensions of SSD will be compatible ?...
Since, you're starting out with coding I wouldn't expect you to be using heavy Integrated Developer Environments, like Visual Studio + Resharper which can weigh heavily on the performance of your cpu and non-volatile memory storage devices. I've focused on budget laptops that should work fine for basic C coding. I've purposely avoided HDDs because they tend ...
This is a rather vague question, but I will do my best to answer it. A budget of $5000 will bring you a long way. My recommendation is a Microsoft Surface Book. Without knowing what the "same performance of standard notebooks" is I can almost guarantee that the this insanely powerful Tablet/Laptop hybrid will fit your needs. You could probably also play some ...
Are there any benchmark tests which compare older i7's to current i7's?
Cinebench (benchmarks) (6700k performs 72% better)
3DMark (benchmarks) (comparison1) (6700k performs 33% better)
Passmark (comparison2) (6700k performs 122% better)
Mixed Benchmarks by AnandTech (comparison) (6700k performs 85% better average)
I wonder why it is that CPU's are being ...
With SSDs, assuming all else is equal - same speed, size etc, then there is no speed advantage in having two separate drives.
Instead you have an element of redundancy. If one fails, you still have the other - less 'eggs in one basket' syndrome.
As both OSes are not going to ever be running simultaneously, I'd see this as the only real advantage. [you could ...
The other answers are technically correct, but are IMHO unlikely to help. The benchmark you care the most about is your real-life usage of the processor.
Watch yourself using the processor and watch how the processor is doing in critical times, for instance by using htop or whatever works for you. Find the critical components, compare measures for those. ...
SDDs are quite conspicuous when it comes to quality and performance. Capacity, read/write times are made very clear so you can buy what you need. Any further optimisation will come down to your OS, and they're usually pretty good. 250 GB is more than I need for programming but if you think you need that then go for it. Depending on the size of the project, ...
The answer is simple: yes, switching from HDDs to SSDs is a huge improvement but that depends on the write and read speed of the SSDs themselves.
Personally I gave up a 1TB HDD for a 240GBs SSD and it was the best choice ever. (programming, OS and gaming refference)
The SSD's write and read speeds are different from one SSD to another. Personally I have ...
I would suggest the Acer.
It has an SSD which improves boot times.
It comes stock with 16GB of RAM, which is the most you will ever need for gaming.
Also, some applications, including possibly Android Studio, will benefit from the extra RAM and the SSD speeds.
With the Acer, you get more bang for the buck without having to upgrade.
Seeing as ...
I can answer your question. In terms of CPU utilization, there are three kinds of programs the average computer user will encounter:
Programs that don't use very much CPU at all (most programs)
Programs that use only one thread of a CPU heavily (a few programs)
Programs that use all threads of a CPU heavily/evenly (a few programs)
So what does that mean ...
Nowadays, many tablets have the same, or more, performance than laptops.The Microsoft Surface Pro 4 is a very good option for portability and performance. It has a beautiful screen, a powerful processor and a generally well built device.
A general rule of thumb is that a 100% increase in memory speed corresponds to a 5% increase in overall performance. This is because memory access is slow relative to the CPU, so CPUs and programs are designed to minimize memory access.
My experience with POV-Ray bears this out: overclocking the RAM/FSB of my computer from 266 MHz to 333 MHz resulted in ...
I recommend getting a secondhand Core 2 Quad Q9650 or Core 2 Quad X9650 (for your purposes, they're all the same CPU, just with different branding). This will give you almost double the single-threaded performance, and four times the multi-threaded performance. You can find them on Ebay for $20-$60.
You'll also want to upgrade your RAM to 4 GB ($60 or so),...
On a laptop, I would recommend an i7 8th gen for your use case. These CPUs are 4 cores for the U (low power), and 6 cores for the H (high performance) series. They have decent single thread performance (only desktop CPUs would have better single thread performance), and have enough cores such that they work very well for multi threaded workloads as well.
Yes, it does work together.
Yes, this motherboard will run both ECC and non ECC ram (always in non ECC mode though) according to AnandTech.
Will the opposite case work?
Depends. ECC unbuffered memory should work on non ECC memory, from LinusTechTips.
could my the graphic card (NVIDIA GTX 570) be the limiting factor in the refresh rate?
It is absolutely this.
The GTX 570 is too old to have a DisplayPort that can handle 3840x2160 at 60hz.
Update your GPU, the CPU can survive a while longer.
You can easily tell if your CPU is the limiting factor by looking at the CPU usage in Task Manager. If the whole CPU ...
You could upgrade to a quad core processor and 4GB of RAM if you intend to keep the motherboard. CPUs codenamed Yorkfield were the latest you could get for the 775 platform (they are about USD 40 on ebay), but make sure that you can fit a sufficient cooler in your case to cool the additional 2 cores and higher clock speed. I don't see a reason why you ...
Both the machines are upgradable to the same extent.
SSD can be added.
More RAM can be added.
Now, Acer comes with the higher specs in ram and SSD. Which extremely reflects your performance.
Now buying is dependent on pricing of the machines. If Acer comes at the same cost of dell or slightly higher or lower then simply choose the Acer blind folded.
According to the product page the Chromebook has a Celeron 3205U Dual Core clocked at 1.5 GHz. The other machines in your list (1, 2, 3, 4) start with Intel Core i5 processors of the 6th or 7th generation usually clocked about one GHz higher featuring Hyper Threading.
Cnet says the Chromebook has M.2 storage, which is better than the typical non-upgradeable ...
The two bottlenecks of file copying are transfering from the external hard drive, and writing to the internal drive. Everything else in a modern computer is much, much faster than the drives.
My recommendation is that you go to a local store and buy the cheapest computer you can find that has one or more USB 3 ports (USB 2 is roughly the same speed as a ...
Is this memory compatible with the ZBook?
"Up to two SODIMMs, for system memory up to 32GB." - HP's website
Will this memory run at 2666MHz or will the computer/cpu limits its use at 2133Mhz?
I have never heard of RAM speeds being bound by a CPU, and even if it was IMO the performance increase is negligible in everyday tasks.
What will bring me ...
