The Intel Core i5 661 carries an on-die GPU, it also hum along to the tune of 3.33GHz, despite the clock speed advantage, the 661 only feature two physical cores. Another feature present in the i5 661 is Turbo Boost. When both cores are active the multiplier can be boosted by 1x, so for the Core i5 661 that would take the multiplier to 26x, resulting in a frequency of 3.45GHz. If just a single core is active then multiplier is boosted by 2x, taking the Core i5 661 to an impressive 3.60GHz frequency.

The new Core i5 661 may just be a dual-core processor, but it's still incredibly fast at 3.33GHz, even when compared to high-performance quad-core parts. Accompanied with the rest of the Core i5 and Core i3 line-up, we finally have Intel moving...

The Intel Core i5 661 is the first CPU we've seen of a new series based on the new Intel Clarkdale design and for want of a better description it lies somewhere towards the top end of the bottom half of Intel's current CPU line-up. In other...

Even at its arguably inflated price, the Core i5-661 represents the sweet spot in the Clarkdale Core i5 lineup. The Core i5-670 adds fractionally more speed (3.46GHz vs 3.33GHz) and Trusted Execution Technology, but drops iGPU speed from 900MHz to...

So where do the Core i5 600 series processors fit into the scheme of things? Well, if it means anything, a quick look at my favorite online retailer found 20 H55 motherboards. Out of the 20, 19 were mATX boards. There was one H57 board, and it was...

Core i3 and Core i5 CPUs with the new Clarkdale core take a significant step towards the mythical system-on-chip where the functions and features are delivered by a single chip, rather than the traditional CPU, chipset and GPU. As things stand you'd...

For about three months now, we have been talking about the next step in Intel's tick-tock strategy of introducing products. All of the new i series CPUs were made using Nehalem architecture, so the new 32 nm CPUs represent only a die shrink, in...

By the way, to use the display output from the integrated GPU, you need the new Intel chipsets, the H55 or H57, the latter having storage acceleration. I used two new motherboards to try out the CPU. Intel's DH55TC is a decent well featured...

The new Core i5-661 is certainly an interesting CPU. It beats Phenom II X4 965 with AMD 785G in almost all tests we performed. However on applications capable of using four CPUs, the CPU from AMD was faster: file compression with WinRAR, DivX encoding...

The Core i5-661 is more than just a dual core version of the Lynnfield core processor. A die-shrink from 45nm to 32nm gave Intel the space to fit both a dual core processor and their latest onboard graphics chip, GMA HD, onto the same package. This...
