Production microprocessors

Intel Core 2 Duo E6300 HH80557PH0362M (BX80557E6300)

As of October 2006, the E6300 is the slowest member from Core 2 Duo E6xxx series. Despite of that, the processor performs quite well when compared with Intel Pentium 4 and AMD Athlon 64/Athlon 64 FX processors. At this time (October 2006) the E6300 has the best price/performance ratio from all Core 2 Duo processors.
Intel E6305 and E6405 dual-core processors stand aside from other members of Core 2 Duo family. Designed for 1-way servers, these two processors are manufactured in 771-land LGA package, and can work only in socket 771 motherboards. Model numbers of these CPUs are derived from model numbers of Core 2 Duo processors, that have identical characteristics. Specifically, the E6305 runs at the same frequency and has the same features as Core 2 Duo E6300, and the E6405 has the same core frequency and features as the E6400. Part numbers of E6305 and E6403 processors are also different from other Core 2 Duo processors - they (part numbers) indicate that processors belong to server-class family. The E6305 / E6405 CPUs were used in the following servers: Dell Poweredge T300, IBM BladeCenter HS12, HP ProLiant BL260c, and others.
Intel Core 2 Duo E6400 HH80557PH0462M (BX80557E6400)

Slightly faster that the E6300, the E6400 microprocessor usually beats in benchmarks most of Intel Pentium 4s, including Pentium 4 Extreme Edition processors. Depending on the application, the E6400 may be as fast as Athlon 64 FX-62, but not slower than Athlon 64 FX-60.
Intel Core 2 Duo E6600 HH80557PH0564M (BX80557E6600)
Author: Mike Walker
Not only the E6600 is running at higher frequency than E6300 and E6400 processors, it also has twice as large L2 cache. This processor is clocked at 2.4 GHz, which is the same as for Athlon 64 X2 4600+ CPU and lower than for Athlon 64 FX60 and FX62 CPUs. Performance-wise the E6600 is faster at this time (October 2006) than any other Athlon 64 X2 and Athlon 64 FX microprocessor.
Intel Core 2 Duo E7200 EU80571PH0613M (BX80571E7200 / BXC80571E7200)
Author: gshv
The E7200, introduced in April 2008 together with Core 2 Duo E8300, was the first CPU from E7x00 series of Core 2 Duo processors. E7x00 CPUs are based on the same Wolfdale core as E8x00 series, and performance- and price-wise are positioned between Core 2 Duo E8x00 series and Pentium Dual-Core family. The E7x00 CPUs have lower Front Side Bus frequency (1066 MHz) and smaller size of level 2 cache (3MB) than more expensive E8x00 CPUs. Some E7x00 models do not include Virtualization technology. At this point of time (October 2009) the E7200 and E7300 processors are obsolete.
The fastest processor from E7x00 series, Core 2 Duo E7600, runs at 3.06 GHz and has 3 MB L2 cache memory. Unlike older E7x00 models, that didn't have Virtualization technology at introduction, the E7600 was released with this feature enabled. In most cases, model E7600 performs as fast as model E8300. In small applications, the Core 2 Duo E7600 has the same or a bit better performance than E8400 CPU. If you're do not run memory-hungry programs then the E7600 is certainly better upgrade / new CPU option than the E8400 due to 20% cheaper price. If you don't mind slightly worse performance, than Pentium E6500 may be even better upgrade option. The E6500 is 35% cheaper than the E7600, while only 5% - 10% slower.

kind of confused...

why 6300 is slower than 6200 or 6400; so,

cant understand if the higher or slower the number, better/worse performance... can u make some kind of chart in faster performance order???

Response: Sorry, the "Find faster/slower CPUs" currently looks only for frequency. Model numbers are pretty good indication of performance

ok thanks, im talking of one chart with overall performance, some has larger; shorter cache L2 or frecuency, even power and cooling advantages-disadvantages... sorry bad english ...

The E8600 is the best CPU what I ever bought. Fast as the lightning.:D I love it.

Recommend changing (related processors around a bit) I think the Intel Pentium Dual Cores

I think the Intel Pentium Dual Cores NOT the old Pentium belongs at the top of the related to the Core 2 duo processors. You seem to have all the other close relations, the mobile the Core 2 Quad etc, but not the Pentium Dual core which is much closer than the old Pentium D line to the C2D.

Response: Pentium Dual-Core and Celeron Dual Cores will be soon added to "related" families.

The first Pentium Dual Core CPU (E2160, E2140, etc) are based on the Allendale architecture that is found in the E4xxx series Core2 family. The latest P DC family (E5xxx) are based on the Wolfdale core, which is from the E7xxx and E8xxx Core2 families.

The last Pentium D line was based on the Presler core, a completely different architecture from what the Core2 CPUs are based on.
