Conroe

The first Intel Core 2 Duo branded processor cores, code-named Conroe (Intel product code 80557), were launched on July 27, 2006, at Fragapalooza, a yearly gaming event in Edmonton, Alberta, Canada. These processors were fabricated on 300 mm wafers using a 65 nm manufacturing process, and intended for desktop computers, as a replacement for the Pentium 4 and Pentium D branded CPUs. Intel has claimed that Conroe provides 40% more performance at 40% less power compared to the Pentium D. All Conroe processors are manufactured with 4 MB L2 cache; however, due to manufacturing defects or possibly for marketing purposes, the E6300 and E6400 versions based on this core have half their cache disabled, leaving them with only 2 MB of usable L2 cache. These Conroe-based E6300 and E6400 CPUs have the B2 stepping.

The family has a 1066 MT/s front side bus, 4 MB shared L2 cache, and 65 watts TDP. These processors have been tested against AMD's current top performing processors (Athlon 64 FX Series), which were, until this latest Intel release, the fastest CPUs available. Conroe chips also experience much lower heat output compared to their predecessors — a benefit of the new 65 nm technology. At launch time, Intel's prices for the Core 2 Duo E6600 and E6700 processors were US$316 and US$530, respectively, each in quantities of 1000.

E6320 and E6420 Conroe CPUs at 1.86 and 2.13 GHz respectively were launched on April 22, 2007 featuring a full 4 MB of cache and are considered Conroes.

Intel has stated that the E6300 and the E6400 are Conroe CPUs with the cache disabled. Allendale core CPUs are the E4XX0 series of CPUs.

At launch time, Intel's price for the Core 2 Extreme X6800 was US$999 each in quantities of 1000. Like the desktop Core 2 Duo, it has 4 MiB of shared L2 cache available. This means that the only major difference between the regular Core 2 Duo and Core 2 Extreme is the clock speed and unlocked multiplier, usual advantages of the "Extreme Edition." The unlocked upward multiplier is of use to enthusiasts which allow the user to set the clockspeed higher than shipping frequency without modifying the FSB unlike mainstream Core 2 Duo models which are downward unlocked only.

Allendale

There was contention as to whether the previously-available low-end Core 2 Duo desktop processors (E6300, at 1.86 GHz and E6400, at 2.13 GHz, both with 2 MiB L2 cache) are specimens of the Allendale core. Prior to Q1 2007, all E6300 and E6400 processors released were Conroe (4 MiB L2 cache) cores with half their L2 cache disabled. The Allendale core, manufactured with 2 MiB L2 cache in total, offers a smaller die size and therefore greater yields.

Quoted from The Tech Report:

You'll find plenty of sources that will tell you the code name for these 2 MB Core 2 Duo processors is "Allendale," but Intel says otherwise. These CPUs are still code-named "Conroe," which makes sense since they're the same physical chips with half of their L2 cache disabled. Intel may well be cooking up a chip code-named Allendale with 2 MB of L2 cache natively, but this is not that chip.<ref> You must specify title = and url = when using {{cite web}}. . The Tech Report (2006-08-08 techreport.com/reviews/2006q3/e6300-vs-sff/index.x?pg=1//techreport.com/reviews/2006q3/e6300-vs-sff/index.x?pg=1) . Retrieved on 2006-11-22. </ref>

Another difference between the premium E6000 series (Conroe core) and the E4000 series (Allendale core) is the front side bus clock rating. The E4000 series are rated to run on a quad-pumped 200 MHz front side bus ("800 MT/s") while the E6000 series are rated to run on a quad-pumped 266 MHz front side bus ("1066 MT/s"). The E4000 series also lack support for Intel VT-x instructions.

The Allendale processors use a smaller mask with only 2 MiB of cache, thereby increasing the number of chips per wafer. Allendale processors are produced in the LGA775 form factor, on the 65 nm process node. E6300 and E6400 CPUs have been made from both the 4 MB Conroe die and the 2 MB L2 Allendale die. The steppings of the chip differs depending on the die used- the Conroe-based E6300 and E6400 are stepping B2 and the Allendale-based E6300 and E6400 are stepping L2.//www.xbitlabs.com/articles/cpu/display/core2duo-e4300.html Core 2 Duo E4300] only uses an Allendale core, released on January 21, 2007.

For example, the QX6700 consisted of two E6700 chips connected together by a 1066 MT/s FSB on one MCM, resulting in lower costs but less bandwidth to the northbridge. The Kentsfield was one socket processor sitting in a LGA775 socket, as well as Core 2 Duo (AMD Quad FX consisted of two dual-core processors in two separate sockets on one motherboard with a 2 x 125 W<ref>You must specify title = and url = when using {{cite web}}.

The quad-core CPU, including the Kentsfield, processes very well with multi-threaded applications (typical for transcoding audio and video, compressing, photo and video editing and rendering, ray-tracing), where its processing ability may approach double that of each of its halves. Each Kentsfield's half comprised an equally clocked dual-core CPU on a separate die. Both dies were in one package similarly to the Pentium D branded processors. A quad-core CPU (as a two-die set in particular), however, can rarely double the processing ability of each of its constituent halves (e.g. the Kentsfield rarely doubles the ability of the Conroe), due to a loss of performance resulting from connecting them (i.e. sharing the narrow memory bandwidth, and operating system overhead of handling twice as many cores and threads).

Single or dual-threaded applications alone, including many games, do not benefit from the second pair of cores of a quad-core CPU over an equally clocked dual-core CPU. For example, the quad-core Extreme QX6700 (Kentsfield) did not process those applications faster than the older dual-core Extreme X6800 (Conroe XE core), because its FSB's speed was the same, and it was clocked slightly slower. Nevertheless, a simultaneous running of several processor-intensive single/dual-threaded applications on the quad-core CPU is generally much faster than on equally clocked dual-core CPU. The quad-core CPU is useful also to run both the client and server processes of a game without noticeable lag in either thread, as each instance (up to four) could be running on a different core. Furthermore, multi-threaded games (see Crysis and Gears of War) benefit from the quad-core CPUs<ref>You must specify title = and url = when using {{cite web}}.

Yorkfield XE

On November 11, 2007, Intel released the first Yorkfield XE processor, Core 2 Extreme QX9650. It is the first Intel desktop processor to use 45 nm technology and a high-k metal gates. Yorkfield features a dual-die quad core design with two unified level-two (L2) caches, with a total of 12 MiB (2 × 6144 KiB) of L2 cache. It also features a 1333 MHz FSB and clock speed of 3 GHz. The processor incorporates SSE4.1 instructions and has total of 820 million transistors on 2x107 mm² dies.

The newest Intel Core 2 Extreme processor that boasts this new core is the Core 2 Extreme QX9650. This chip has a clock speed of 3.0 GHz and a FSB of 1333 MHz, and features new SSE4.1 instructions. SSE4.1 can greatly speed up tasks such as some key operations in video encoding. Intel released sixteen new 45 nm Penryn processors on November 12, 2007. However, all but the QX9650 were Xeon models.

Intel has announced its new 45nm Penryn-based Core 2 Duo and Core 2 Extreme processors will be released on January 6, 2008. The new processors will launch exclusively with a 35W thermal envelope. The new processors are slated to be unveiled further at MacWorld 2008 as part of Apple's mobile lineup.<ref>You must specify title = and url = when using {{cite web}}.

System requirements

Motherboard compatibility

Conroe, Conroe XE and Allendale all use Socket LGA775; however, not every motherboard is compatible with these processors.

Supporting chipsets are:

The currently released Yorkfield XE model QX9650 (45nm with 1333fsb) currently has limited chipset compatibility - with only X38, P35 and some 975X motherboards being compatible. BIOS updates are gradually being released to provide support for the new penryn technology.

Synchronous memory modules

Unlike the previous Pentium 4 and Pentium D design, the Core 2 technology sees a greater benefit from memory running synchronously with the Front Side Bus (FSB). This means that for the Conroe CPUs with FSB of 1066 MT/s, the ideal memory speed for DDR2 is PC2-4200 or PC2-8500 (twice the speed of PC2-4200). In some configurations, using PC2-5300 can actually decrease performance. Only when going to PC2-6400 is there a significant performance increase. While expensive DDR2 memory models with tighter timings do improve performance, the difference in real world games and applications is negligible.<ref>You must specify title = and url = when using {{cite web}}.

The Core 2 processor does not require the use of DDR2. While the Intel 975X and P965 chipsets require this memory, some motherboards and chipsets support both the Core 2 and DDR memory. When using DDR memory, performance may be reduced because of the lower available memory bandwidth.

Chip bugs

The Core 2 Memory management unit (MMU) in X6800, E6000 and E4000 processors does not operate as previously specified or implemented in previous generations of x86 hardware. This may cause problems, many of them serious security and stability issues, with existing operating system software. Intel's documentation states that their programming manuals will be updated "in the coming months" with information on recommended methods of managing the Translation Lookaside Buffer (TLB) for Core 2 to avoid issues, and admits that, "in rare instances, improper TLB invalidation may result in unpredictable system behavior, such as hangs or incorrect data."<ref>You must specify title = and url = when using {{cite web}}.

  • Floating point instruction non-coherencies.
  • Allowed memory corruptions outside of the range of permitted writing for a process by running common instruction sequences.

Intel errata Ax39, Ax43, Ax65, Ax79, Ax90, Ax99 are said to be particularly serious. 39, 43, 79, which can cause unpredictable behavior or system hang, have been fixed in recent steppings.

Pricing

The pricing for various models of Core 2, in lots of 1000 to OEMs, at the time the processors were released, can be found in the list of Intel Core 2 microprocessors. It should be noted that these prices are what it costs system builders such as Dell and HP to stock Core 2 processors. There are no set MSRPs for Core 2 CPUs in the retail channel — prices at retailers are usually very close to the aforementioned prices, but are dependent on what the supplier is charging to stock these CPUs as well as supply and demand.

Nomenclature and abbreviations

With the release of the new Core 2 processor, the abbreviation C2 has come into common use, as well variants C2D (the present Core 2 Duo), and C2Q, C2E to refer to the Core 2 Quad and Core 2 Extreme processors respectively. C2QX stands for the Extreme-Editions of the Quad (QX6700 or QX6800).
