3DMark Wants to Benchmark Everything

by Leave a Comment

3dmark logo3DMark, the go-to benchmarking software, is not only improving it’s Windows based tests but it’s also moving onto other types of hardware besides the PC. Apple iOS, Android, and Windows RT are all fair game when it comes to being benchmarked by 3DMark.

I must admit that I never really thought about benchmarking my smartphone, it’s kind of interesting idea. We read the specs on our tablets and smartphones and we know how much memory we have  and what our screen resolution is but do we really know just how much power we have to work with ?

When it comes to performance in multitasking, surfing the web, or gaming we really don’t think of measuring it all, at least not as often as we should. For the most part we download our apps and they run, but can they run better? How far can we push the hardware, what are the limitations, and how does it stand up against the competition?  These are all great questions that can be answered by a trusted benchmark tool that provides a standard to go by.

The new benchmarks are visually, much improved and a leap ahead from previous iterations. There are three benchmarks, FireStrike for Windows gaming PC’s, CloudGate for Windows Notebooks and home PC’s, and Ice Storm for Android, iOS and Windows mobile. This is great for enthusiasts who really want to get a clearer picture of what’s going on under the hood of their favorite non-PC devices.

To make things even better, the basic version is free and can be found at 3DMark along with complete details on the benchmarking software.

How To Test Your CPU Performance with SuperPi and wPrime

superPi

For a custom PC builder there’s nothing more satisfying than finishing up your build so you can put it to the test. Sure you can open up an application and perform certain tasks to give you an idea of how your new build is performing, but you can also use specific programs that are designed specifically to benchmark.

One of these applications is actually quite simple. SuperPi calculates Pi to a specific number of digits and then displays the time it took to calculate the answer for each iteration. You can also determine the accuracy of the calculation which can also help determine stability of the system, this is perfect for overclocking.

It’s important to note that SuperPi is intended to test single threaded performance, if you’re looking to test multi-threaded performance you can utilize wPrime.

wPrime uses a recursive call of Newton’s method for estimating functions, with f(x)=x2-k, where k is the number we’re square rooting, until Sgn(f(x)/f'(x)) does not equal that of the previous iteration, starting with an estimation of k/2. It then uses an iterative calling of the estimation method a set amount of times to increase the accuracy of the results. It then confirms that n(k)2=k to ensure the calculation was correct. It repeats this for all numbers from 1 to the requested maximum.
