While not yet a common term, over the past year or so we have started to see a rise in the usage of the term "Aggregate CPU Frequency". It seems reasonable enough: take the frequency of the CPU and multiply by the number of cores to arrive...
With 4K monitors becoming more and more affordable, it appears that the long-standing reign of 1080p may finally be coming to a close. The question is: can the human eye actually see the difference with a 4K monitor? To answer that question we will need to determine the pixel pitch of a monitor and compare it to what you are actually capable of seeing.
You may be familiar with Intel naming their processors under the Core i7, i5 and i3 moniker based on the performance and features offered. But beyond that there are also a handful of different product lines within each of those brands identified by a K, X, S or T appended to the model name. In this article, we'll cover the 'S' product line in particular to determine the actual performance, power draw, and thermal differences compared to its standard counterpart.
Older CPUs would simply fail if they started to overheat, but modern CPUs adjust their frequency based on temperature (among other things) to prevent a dramatic failure. Because of this, it stands to reason that once you reach certain temps, you will no longer be getting the maximum performance from your CPU because it will be busy protecting itself. But what is that temperature? And do you really need a high-end liquid-cooled system to get peak performance?
A SED, or self-encrypting drive, is a type of hard drive that automatically and continuously encrypts the data in it without any user interaction. What may surprise many is that a decent potion of the drives currently in the market are in fact SEDs. The method involves a Data Encryption Key that encrypts and decrypts data whenever data is written to the drive or read from it. But the process is so transparent to user that it is unlikely they would ever realize they have such a feature.
Much of the ECC versus Non-ECC argument comes down to speed versus reliability. The reliability argument at least is easy to validate, but to settle the question of whether ECC actually lowers system performance, we ran a series of benchmarks with standard RAM, ECC RAM, and Registered ECC RAM that all run at the exact same frequency, timings, and voltage.
We've all been there. You want to buy a new graphics card, you read the reviews, and settle on the best GPU within your budget. Then you have to decide from half dozen or so manufacturers that offer nearly identical hardware. But which is the most reliable? The same scenario could be applied to other components like motherboards, storage or memory. That's why when we found this annual list compiled by boutique PC manufacturer Puget Systems we asked them to reproduce it for you.
