The Core i5 CPU knocked it out in 1 minute and 12 seconds, 16 seconds faster than the category average. The Core i7 did it a only few seconds faster, at , for a mere 4. But which does it better? On the 3DMark Ice Storm Unlimited benchmark, which tests the overall graphics performance , the Core i5's GPU hit 78,, falling just short of the 78, ultraportable notebook average. Meanwhile, the Core i7 nailed an 83,, effectively making it 5. With great power comes great power consumption, so we decided to test that by having each laptop continuously surf the web over Wi-Fi at nits of brightness.
The Core i5 lasted 10 hours and 51 minutes, sailing past the ultraportable notebook average. However, the Core i7 stood its ground and survived for 10 hours and 49 minutes, making an unnoticeable 0. Some laptops, like the massively expensive Alienware Aream , actually come with a desktop i9.
Not only is the K cheaper, but it also has fewer issues with power and thermals, and it comes with two more cores and four more threads.
If you have workloads that can use the extra power of an i7, consider springing for an i9 especially if you can get a last-gen chip on sale. Laptops are a different beast. Your processor can process more information at once, thanks to more threads and cores. Instead of stressing a single core or thread, the processor spreads out the workload. So, the benefit of more cores and threads is clear: It allows the processor to better handle multitasking.
Some applications are explicitly optimized to capitalize on multiple threats, in conjunction with most file compression and decompression, Adobe Premiere, and Handbrake apps. There are only a few applications that still use a single thread or core from your computer.

What's the difference? Is it worth it to own a CPU with more cores, a faster clock-speed or advanced features like hyper-threading?
If you're building your first PC, the main thing you need to keep in mind here is that the 3, 5 and 7 attached to each family of Intel Core processors are simply meant to be indicative of their relative processing power. Which family an Intel Core CPU falls into is based on a collection of criteria involving their number of cores, clock speed in GHz and cache size, the number of Intel technologies they integrate also plays a role.
At the most basic level, these numbers reflect where each class of Intel Core CPU sit relative to one another and are intended to give consumers an idea of the kind of performance they should expect from each. Essentially, the idea that Intel are looking to convey with this CPU classification system is that PC builders should expect:.
Some are intended for us inside laptops, others are intended for use with desktop PCs. Wattage is the big differentiator here, since CPUs inside mobile devices generally have to make do with less power draw,. However, to avoid confusion, let's start by exclusively talking about the desktop variants. This means that a PC with a higher core-count is going to be better for tasks where multithreading is important, such as web servers, web browsers and some video games.
The reason for this is that i3 processors are designed to hit a lower price-point more than they are push boundaries for performance. They tend to be found inside PCs that target a more budget-conscious market-segment where the need for a device to be affordable eclipses the demand for higher performance.
It is dual-core or quad-core processors. You can use it on both desktop and laptop computers. If you are playing solitaire, then you will not see much between Core i3 and Core i5 processors. However, If you are editing multiple files in Adobe Photoshop, you can see that Core i5 performs the same task faster compared to old generation processors.
Core i7 is a family of high-end performance x86 bit processors developed by Intel. It is designed for high-end desktops and laptops. It is the first processor generation using Nehalem Microarchitecture.
