2.4 vs 5
Quad-core i7 mobile processors do deliver increased performance but may sacrifice some battery life to do so. So there is a smaller performance gap between i5 and dual-core i7 mobile processors. All Core i5 and i7 mobile processors support hyper-threading. Core i5 mobile processors are dual-core and so are some i7 processors, while other i7 CPUs are quad-core. Specifications for Mobile i5 and i7 Processorsįor the mobile versions of Ivy Bridge i5 and i7 processors (used in laptops and netbooks), things are a little different. i7 processors on the desktop support hyper-threading while Core i5 processors on the desktop do not. Specifications for Desktop i5 and i7 CPUsĪll Core i5 and Core i7 Ivy Bridge processors for desktop have 4 cores and a Direct Media Interface with Integrated GPU.ĭesktop versions of both i5 and i7 Ivy Bridge processors are quad-core. As discussed above, all Core i7 processors and mobile i5 processors support hyper-threading. Intel Hyper-Threading increases CPU performance for multi-threaded tasks and is helpful for multitasking when several applications are running simultaneously. Both Core i7 and i5 processors support Turbo Boost. Turbo Boost is Intel's terminology for overclocking CPUs, allowing them to run faster than their base clock speed. Concise, useful information about older models is available on Wikipedia ( for i5 and for i7) This comparison will focus on the latest (Ivy Bridge) models. There are several generations of Core i5 and i7 processors, the latest being Ivy Bridge, preceded by Sandy Bridge, Westmere and Nehalem.
According to APC Magazine, only $40 separates the different i5 chips, with a $120 difference between i5 and i7. I5 systems are typically cheaper than comparable i7 systems by about $150. However, they suggest that the i5-3750K is the best option, as it is perfectly between the i5-3450 and the i7-3770K in terms of performance, but is far closer to the i5-3450 in price. The i7-3770K delivered 89.3fps.Īccording to APC Magazine, there is some benefit to using i7 if ripping DVDs and converting them to. With 1080p, the i5-3450 delivered 81.6fps on Crysis, while the top Core i5, i5-3550 delivered 86.7.
Instead, memory ( RAM) and storage ( SSD instead of an HDD) provide greater bang for the buck for increased performance from a computer.Īccording to a study by APC, the difference between the Core i5-3450 and the top-end Core i7-3770k is about 10%. i7 processors feature a larger cache, hyper-threading, and a higher clock speed.Įven so, computer processors are rarely the bottleneck in performance these days. These are intended to be brief notes, and you should be able to find more information in either the New Features document, or in the src/CHANGES file.
2.4 VS 5 PC
Intel Core i7 is a high-end processor and is more appropriate than the i5 processors for certain intensive tasks, such as data crunching, graphics and video editing, and PC gaming.
