Core i7 vs i5

We’ve extensively covered the differences between Xeon and i5/i7 previously in this forum. Now let’s go over the differences between Intel’s Core i7 vs i5. Who needs which processor? Is the i7 always worth the additional investment?

Intel Core i7 – the Pros

i7 vs i5More Cache – L3 Cache is where the processor stores recent calculations to speed them up for future calculations. For example, when working in a spreadsheet, the CPU stores the framework for each number and formula in the cache, making recalculations appear almost instantly. Core i5’s have L3 cache but on average, you get about 20% more with an i7.

Higher lock Speed – Though a higher-end i5 does compare favorably to a lower-end i7 in terms of base clock speed, there’s no competing against the top of the line i7’s like the Core i7-6700k. If you need the fastest core speed possible– and subsequent turbo boost – i7 wins hands down.

Hyperthreading – This is the biggie. Hyperthreading (abbreviated as HT often on our site) means that in addition to the four/six/eight/ten physical cores, the processor has an equal number of threads or “virtual cores,” effectively doubling the number of available processing cores. For applications optimized to recognize and utilize these threads, that translates into a significant boost in performance.

Intel Core i5 – the Pros

i5 vs i7Value – the lower price point of the Intel Core i5 series translates into better value for many consumers, especially if your application does not take advantage of the performance advantages outlined above.

Quad Core – Though lacking the Hyperthreading feature of the i7, all Core i5 processors still have four physical cores, making it great for mid-level multitasking and applications not specifically optimized to access virtual cores.
