Intel Core i5 660/661 CPU vs Core 2 Duo E8600 vs AMD Athlon X4 Review & Benchmarks

Intel Core i5 660/661 CPU Review and Specifications and Benchmarks vs core 2 Duo E8600 vs AMD Athlon X4 630/965

Here you can find benchmark test of six CPU from Intel and AMD from our friends in , so lets begin with the features and specification of each CPU:

The new processors have a great potential for price cuts, especially as their process technology matures. The second important benefit is original architectural features which let dual-core processors feel all right among quad-core ones. The third benefit is that the new processors are actually new. Their rollout will allow the company to introduce proper order in its market share, because three similar chipsets is too much.

 Intel core 2

Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core CPUs based on the Intel Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module.The introduction of Core 2 relegated the Pentium brand to the mid-range market, and reunified laptop and desktop CPU lines, which previously had been divided into the Pentium 4, Pentium D, and Pentium M brands.

The Core microarchitecture returned to lower clock rates and improved the usage of both available clock cycles and power when compared with the preceding NetBurst microarchitecture of the Pentium 4/D-branded CPUs.
The Core microarchitecture provides more efficient decoding stages, execution units, caches, and buses, reducing the power consumption of Core 2-branded CPUs while increasing their processing capacity. Intel's CPUs have varied wildly in power consumption according to clock rate, architecture, and semiconductor process, shown in the CPU power dissipation tables.

Intel Core i5

On September 8, 2009, Intel released the first Core i5 processor: The Core i5 750,[1]  which is a 2.66 GHz quad-core Lynnfield processor with Hyper-threading disabled. Lynnfield Core i5 processors have an 8 MB L3 cache, a DMI bus running at 2.5 GT/s and support for dual-channel DDR3-800/1066/1333 memory. The same processors with different sets of features (Hyper-Threading and other clock frequencies) enabled are sold as Core i7-8xx and Xeon 3400-series processors, which should not be confused with high-end Core i7-9xx and Xeon 3500-series processors based on Bloomfield.

The Core i5-5xx mobile processors are named Arrandale and based on the 32 nm Westmere shrink of the Nehalem microarchitecture. Arrandale processors have integrated graphics capability but only two processor cores. They were released in January 2010, together with Core i7-6xx and Core i3-3xx processors based on the same chip. The L3 cache in Core i5-5xx processors is reduced to 3 MB, while the Core i5-6xx will use the full cache and the Core i3-3xx will have no support for Turbo Boost[2]. Clarkdale, the desktop version of Arrandale, is sold as Core i5-6xx, along with related Core i3 and Pentium brands. It has Hyper-Threading enabled and the full 4 MB L3 cache.

The Clarkdale CPUs : 

All of the three new series -- Core i5-600, Core i3-500 and Pentium -- are based on the same chip, the further development of the Nehalem. As have already said, one of the key advantages of the new architecture is its "modular" nature that provides excellent scalability in terms of the number of cores, both upward (from the initial 4 to 6 and 8 in prospective LGA1366 models) and downward. This is a considerable difference from the Core 2 architecture which is strictly dual-core. (Well, there are quad-core and hexa-core processors of that design too, but their cores are connected mechanically, which complicates data exchange between cores and results in other issues.) So, as a CPU, Clarkdale is the example of the downward scalability: it has two cores instead of four, but each is completely identical to those found in Bloomfield and Lynnfield. Against all expectations, Clarkdale even has the same L1 and L2 caches: 64KB and 256KB, respectively. The L3 cache is halved down to 4MB. Since cache occupies a large part of a CPU these days, all these changes are bound to reduce processor cost price. Smaller is cheaper even within the same process technology. However, the latter has changed from 45nm to 32nm. All of these efforts can reduce the cost price by a factor of three. In other words, while Lynnfield can be in processors for $200 and more, Clarkdale can be featured in solutions sold below $100. And it does just that in the form of the new Pentium."
