Intel Core i3-530 - CM80616003180AG / BX80616I3530 / BXC80616I3530
Author: gshv
Core i3 is an entry-level Core-branded family, positioned to compete with AMD Athlon II X3/X4 and Phenom II X2/X3 families. First two members of the Core i3 family, Core i3-530 and i3-540, were released on January 7th 2010 at Consumer Electronics show in Las Vegas. The CPUs are based on Westmere micro-architecture (enhanced Nehalem micro-architecture), and have all basic features of the micro-architecture - 256 KB level 2 cache per core, shared level 3 cache, support for SIMD instructions up to SSE4, Virtualization and Hyper-Threading technologies. There are a few Westmere/Nehalem features, missing from all Core i3 microprocessors. Core i3 doesn't have Turbo Boost technology, which temporary increases frequency of one or more CPU cores. Core i3 processors also lack new AES instructions, Trusted Execution technology and support for VT-d virtualization. The slowest from first two Core i3 CPUs, i3-530, runs at 2.93 GHz, which is %13 slower than the fastest Core 2 Duo CPU E8600. Not surprisingly, the i3-530 is about 10% slower than the E8600 in office and game applications. Many media applications, such 3D processing, and audio and video encoding/decoding, are heavily multi-threaded, therefore Core i3 CPUs with Hyper-Threading feature perform better in them than in office or game applications. In media applications the i3-530 CPU sometimes is as fast as the dual-core E8600, and often up to 15% faster.
With 3.2 GHz core frequency, the third member of desktop Core i3 family, i3-550, has a lot in common with more expensive Core i5-650 model. In comparison with the 650 CPU, the most important missing consumer feature on the i3-550 is Turbo Boost technology. The Core i5-650 also incorporates Vpro features and SSE instructions, which are not supported by the i3-550 model. Despite of missing features, the Core i3-550 performs quite well in comparison with the i5-650. In our benchmarks the 550 was up to 9% slower in single-threaded applications, and from 0% to 5% slower in multi-threaded benchmarks. Currently, in June 2010, the i3-550 is officially priced at $138, or about 27% lower than the price of the 650 CPU. This makes the i3-550 much more cost effective than feature-rich i5-650 model.

Additional information

Integrated HD graphics on Intel microprocessors was introduced in Westmere group of families, and it was significantly improved since then. With more and more features added to each generation of integrated GPUs, it becomes more difficult to find out what features are supported on specific integrated graphics unit. The purpose of this article is just that: to provide a comprehensive listing of all supported features for all generations of integrated Intel GPUs.
