Core 2 Duo vs Core i3: The Veteran vs. The RookieThe Core 2 Duo has been the processor of choice in laptops for about three years. Over those three years the average speeds of Core 2 Duo processors have advanced significantly, and many of today’s Core 2 Duo laptops have speeds of around 2.2Ghz or faster. Core 2 Duo processors have also been the go-to for many less expensive desktop systems, with speeds reaching over 3Ghz. However, there is a newcomer which is challenging the Core 2 Duo. This is the Core i3. It is very similar to the Core 2 Duo in many ways. Both are dual-core processors and most Core 2 Duos and Core i3 have similar clock speeds. However, the processors are based on different architectures. So, which one is better? ArchitectureCore 2 Duo Cpu ComparisonThe Core 2 Duo processors are based off the Core 2 architecture. The Core and Core 2 architectures were arguably Intel’s most successful architectures, as they replaced the Pentium 4 processors in desktop systems and made Intel competitive in that space once again. The Core i3 is based off a new architecture called Nehalem. The Nehalem architecture has numerous advantages over the Core 2 architecture. Insidious chapter 4 full movie putlocker. Nehalem is better constructed for quad-core processors, has hyper-threading available, and can use a feature called Turbo Boost which maximizes processor speed. However, because the Core i3 is the low-end Nehalem variant, most of these features are disabled or not relevant – the Core i3 is a dual core processor and Turbo Boost is disabled, but hyper-threading is enabled. Processor PerformanceThe Core i3 is the slowest variant of the Nehalem based processor. The Core 2 Duo processors, however, don’t have the same differentiation between versions of the same architecture. The fastest Core 2 Duo desktop processor has a speed of 3.33Ghz, while the fastest Core i3 desktop processor is clocked at 3.06Ghz. You might therefor expect that the Core 2 Duo would have the edge – particularly when you consider that the Core 2 Duo costs almost three times as much if you buy it individually – but in fact the Core i3 is faster, and often by no small margin. The Core i3 is faster even in single-threaded applications, but the performance gap really widens in multi-threaded applications. This is because the Core i3 has hyper-threading, which turns the two real cores into four virtual cores. Windows works with the Core i3 as if it is a quad-core processor. Core Duo Vs Core 2 DuoThese results remain true in the mobile space, as well. Core i3 processors punch at least 500Mhz above their weight in single-thread applications, and are virtually always faster in multi-threaded applications, no matter the clock speeds of the Core 2 Duo and Core i3 processors you are comparing. Power Usage and HeatA look at the technical specifications of the Core i3 processors automatically puts them into a negative light when it comes to power consumption. The desktop Core i3 parts at listed as having a 73 Watt TDP, while most Core 2 Duo desktop parts have a 65 Watt TDP. In laptops the Core i3 has a 35 watt TDP, while Core 2 Duo mobile processors usually have a 25 Watt TDP. These differences pan out about how you’d expect them to when it comes to absolute power consumption. The Core i3 processors do consume just slightly more power than Core 2 Duo processors at load and at idle. We’re talking a difference of around 10 Watts on desktops and a few on laptops – nothing huge, but a difference none the less. However, when it comes to power efficiency the answer becomes less clear. In order for a processor to be power efficient, it needs to not only have low power consumption but also the ability to complete tasks quickly. This lowers the overall 'task energy' because a faster processor will be done with a task before a slower processor, and once done it will slip back into an idle state. Intel Core 2 Duo ProcessorWhen viewed from this perspective, the Core i3 is much more efficient than the Core 2 Duo on both the desktop and the laptop. This means that the Core i3 will probably not use any more power than a Core 2 Duo – and may actually use less – unless your usage patterns place a constant load on your processor. VerdictPokemon gba roms for pc. Overall, the answer is clear – the Core i3 is the better processor. That doesn’t mean that it absolutely body-slams the Core 2 Duo. The Core 2 Duo isn’t hugely slower. However, the Core 2 Duo is on its way out, and the Core i3 is slightly better in just about every way. In the desktop space, the ease with which you can find a Core i3 desktop means there is little reason to purchase a Core 2 Duo based system unless you’re on a very tight budget. On laptops, however, the story is a bit different. There are still some competent Core 2 Duo systems available, and they’re worth considering if their other advantages out-weight the slightly out of date processor. This post is part of the series: Core i3, i5, and i7 Explained
It is often difficult to discern which new processors are the best. This guide to Intel’s new Core i3, i5, and i7 processors gives advice and information about them so that you can decide which processor is best for your needs.
If you are looking for an entry-level laptop or desktop computer, the core i3 vs. core 2 duo comparison presented here will be a helpful read. Being the two main entry-level processor lines developed by Intel, a comparison of first, second and third generation core i3 series with core 2 duo processors will help you make an informed decision.
Why Upgrade to Core i3?
Hyper-Threading, DMI bus, higher processing speed and HD 2500/4000 graphics, along with low power consumption provided by the i3 lines make them worth an upgrade. We live in times where computing power, once available only at the level of super computers, is now within grasp of the common man. The forerunner in this race to provide the fastest computer processors, who's probably miles ahead of its competitors, is the computing giant Intel. The company delivers chips with varying degrees of power and clocking speed to serve the diverse requirement levels of its users. These include the entry-level, mid-level and high-end processors. The core i3 processors, now in their third generation Ivy Bridge line have supplanted the core 2 duo line in the entry level domain. In fact the old core 2 duo line was overthrown by the first two generations of i3 processors long ago. The new hierarchy of Intel chips, in ascending order of computing power, are the core i3, i5 and i7 processors.
All these lines have now evolved to their third generation with the 22nm Ivy Bridge architecture being the latest. Although core 2 duo processors are slowly being phased out of production, they are still available in the market. The old war horses are still in use all over the world. In this Techspirited article, I present a comparison of third, second and first generation core i3 vs. core 2 duo processors, which may help you decide which one to go for. If you can't make up your mind about whether or not, an upgrade to a core i3 line would be worth it, keep reading ahead.
A comparison between processors was simple some years ago with a single core processor. All you had to look at was the clocking frequency and cache size. The entry of multiple core chips changed it all and life became complicated. With dual, quad and even six core processors hitting the market, there are many more factors to be considered, than before. Intel's dual core and core 2 duo processors were the first ones to introduce multi-core processor based computing.
Today, Intel has gone through a phase of radical innovation to introduce three successive generations of core i3 processors, that are a significant improvement over the core 2 duo line. The following comparison will provide an overview about how the i3 processors are different from their dual core predecessors. The two points of comparison will be technical specifications and the only other factor which matters, which is - performance.
Technical Specifications
Like the core 2 duo processors, the new core i3 line of processors have two cores, with many other technological enhancements, including an integrated GPU (Graphic Processing Unit). The clocking frequency of the core i3 series of processors ranges from 2.26 GHz to 3.06 GHz.
Each processor is endowed with the new line of advanced technologies including Intel developed Hyper-Threading, Intel Virtualization and Smart Cache technology which makes these chips faster than core 2 duo processors. This is the most important point in this core i3 vs. core 2 duo comparison.
The Intel codename for the first generation core i3 architecture is 'Clarkdale'. They are based on Westmere architecture with 32 nm fabrication and a direct media interface (DMI) bus. The socket type used for core i3 processors is LGA 1156 and the RAM type is DDR3. They support mother boards with the following types of chipsets- H55, P55, H57 and Q57.
In mid-2011, a second generation Intel core i3 series was launched, consisting of 17 processors. It includes the core i3-2100 desktop series and the core i3-2300 mobile processor series. They are enabled with some new technologies, which include Intel Fast Memory Access, Intel Flex Memory Access, Quick Sync Video, InTru 3D Technology, Thermal Monitoring Technologies and Intel Insider, which are not available in the first generation core i3 series of processors. Besides a doubled DMI operating speed (5 GT/sec) and lowered power consumption, they are equipped with the Intel HD Graphics 2000 technology.
Very recently, a reincarnation of the core i3 was launched in the form of Ivy Bridge microarchitecture with a 22 nm manufacturing process. Using tri-gate or 3D transistors, Intel has managed to add more transistors in lesser space creating high-performance, power-efficient chips. With Hyper-Threading (simultaneous multithreading) enabled, the two built-in third generation core i3 processors can work on four threads simultaneously, thus making parallel computing possible. Besides the substantial boost in computing power, these chips offer 3 MB smart cache, with on-board Intel HD 4000/2500 graphics that can run intensive graphics without an external video card. In both desktop and mobile domain, these processors currently rule the market.
So how does the old dual core line measure up against these computing 'young turk' core i3 processors? Let's find out. Core 2 Duo processors came in three types of architectures, codenamed as 'Conroe', 'Wolfdale' and 'Allendale'. With 65 nm and 45 nm fabrications, they are a tad slower and less power efficient than the 32 nm/22nm based core i3 processors. The socket used for core 2 duo processors is LGA 775 and they come with a FSB bus. This bus type is a lot slower in operation, compared to the DMI bus in core i3 processors.
Coupled with the fact that i3 processors have a L2 cache size of 2 x 256 Kb and a L3 cache size of 4MB/3MB, with Hyper-Threading and Smart Cache enabled, core 2 duo processors are indeed slower. Moreover, DDR3 compatibility in core i3 processors, compared to DDR2 compatibility of core 2 duo processors, makes them faster. The price range of Intel core i3 is $100 to $133, which makes them top options in the entry-level market. The price of the third and second generation core i3 line ranges from $117 to $250. On the other hand, the price range of core 2 duo desktop line, which is still in production, ranges from $112 to $285.
Performance Compared
The technical specifications have made it clear that Intel core i3 beats its predecessor, core 2 duo, in almost all departments and in all three generations. This is but natural, as they were indeed designed to replace them. Be it processing speed, multitasking or graphic output, opting for core i3 processors is the logical choice to make. It is also clear that the second generation core i3 line has already been superseded by the third generation. Things change very rapidly in the technological arena. So if you want to go for the best entry-level processors, choose from the third generation core i3 line of processors. For your convenience, I have listed the best core 2 duo, core i3 (1st, 2nd and 3rd generation processors) in the following table.
Dual core chips will always stay in vogue, despite the onslaught of quad and hexa-core processors, as they serve the multitude and most software programs are still built to utilize two cores at the most. Going for an advanced line of processors is always beneficial in the long run. You should also check out the Intel core i5 and core i7 processors before going ahead, as they offer far more computing power and speed, compared to the entry-level core i3 or core 2 duo lines. Decide on the processor you want, according to your usage requirements and of course giving due thought to your vitamin 'M' levels, before choosing one!
The Intel Core 2 Duo E8400 is a middle level processor whichruns on the LGA 775 chipset. With a speed of 3.0 GHz running on two cores, ithas a 6MB cache which offers fast access to the programs that you need themost. It’s also built to overclock, and can reach 3.8 GHz without the need ofovervolting. It’s also more energy efficient than its Quad Core counterparts, witha TDP of only 65W. Thus, this processor is suitable for budget minded gamersand enthusiasts alike. For extreme value without breaking the bank, the new andimproved dual core is here: the Core 2 Duo E8400.
