Intel Pentium Dual-Core E2140 - HH80557PG0251M / BX80557E2140 / BXC80557E2140
Author: xcarlos

Traditionally, the Pentium brand has always been associated with high-performance desktop processors. Starting from the Pentium Dual-Core family, the brand was "downgraded" to medium-performance and medium-priced processors. During its introduction, in May 2007, the family was positioned between Core 2 Duo family and single-core Celeron 400 series family. First two members of family were E2140 and E2160. Both processors had 1 MB level 2 cache - 2 or 4 times smaller than the level 2 cache on Core 2 Duo processors, but 2 times larger than the L2 cache on Celeron 400 series CPUs. Processor's frequency and Front Side Bus frequency was comparable to those frequencies of Celeron 4xx and the slowest Core 2 Duo processors.

Pentium Dual-Core E2160 is very similar to the slowest member of Core 2 Duo family, Core 2 Duo E4300 CPU. Both processors run at the same core and FSB frequency, have the same size of level 1 caches, and include pretty much the same core features. The only difference between them is the size of level 2 cache - 1 MB for the E2160, as opposed to 2 MB for the E4300. Having smaller L2 cache, the E2160 is up to 20% slower in memory intensive applications, including games, but performs at the same level in CPU intensive applications (3D rendering, encoding, and others).

Pentium E5500 and E6000 lines of microprocessors use the same Wolfdale core with 3 MB level 2 on-die cache, but processors from the E6000-series have larger size of L2 cache enabled - 2 MB as opposed to 1 MB for E5500-series. Other improvements in the E6000 series is 266 MHz higher Front Side Bus frequency, and included from the start Virtualization technology.

Pentium E6300 was the first microprocessor from E6000-series. The fastest processor in May 2010, when the E6300 launched, was Pentium Dual-Core E5400. The E6300 had not only larger size of L2 cache and faster FSB, but also 100 MHz faster clock frequency (2.8 GHz).
Intel Pentium Dual-Core E6500K - AT80571XH0772ML / BXC80571E6500K
Author: gshv
Pentium Dual-Core E6500K is the first Intel's low-priced microprocessor with unlocked clock multiplier. While the E6500K does not offer extreme performance like Core 2 Extreme processors, it's more than 10 cheaper than the cheapest Intel Extreme processor. At the time of its introduction, beginning of August 2009, this CPU is sold only in China.
Intel Pentium Dual-Core G6950 - CM80616004593AE / BX80616G6950 / BXC80616G6950
Author: gshv
Pentium G6950 is the only processor from Pentium Dual-Core family (now branded as "Pentium"), which was released in the first batch of Intel 0.032 micron microprocessors at the Consumer Electronics Show in Las Vegas in January 2010. The G6950 processor runs at 2.8 GHz, that is a bit slower than the fastest Pentium Dual-Core processor at present time (January 2009). On the other hand, the G6950 is based on newer Westmere micro-architecture, and, as such, has on-chip memory controller and graphics processor, and includes large shared level 3 cache. Being a budget processor, the Pentium G6950 lacks advanced features found in many Nehalem/Westmere processors. The Pentium CPU doesn't support Hyper-Threading and Turbo Boost features, and doesn't include new AES instructions. The G6950 has only 3 MB level 3 cache, as opposed to 4 MB or 8 MB L3 cache in Core-branded processors. The biggest advantage of the new Pentium microprocessor is its low price. At introduction, the G6950 was priced for $87 - much cheaper than any other 0.032 micron processor at the time.

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.
