What's the difference between the Core Duo and Core 2 Duo?

Question

What's the difference between the new Intel Core Duo processor and the Core 2 Duo processor? Just better quality, more durable, faster?

Answer 1

In case you don't wanna read a whole book about it, the Core 2 Duo is based on brand new architecture that is faster and more efficient than the old architecture. The Core Duo is still based on the old Pentium M architecture, with just 2 cores instead of one.

Answer 2

the difference thats between a pentium 3 and a pentium 4

Difference between Merom core (Core 2 Duo) and Yonah core (Core Duo):::

Compared to Intel Core Duo (Yonah), Intel Core 2 Duo (Merom) has larger L2 cache, slightly deeper pipeline and added decode and execution units. In addition, Merom features more aggressive pre-fetch mechanisms than Yonah, as well as Intel’s Memory Disambiguation technology that allows for out-of-order loads. In other words, not only is Merom able to process more data at once, at a faster speed, but it can also get access to that data quicker.

According to Anandtech

Overall, Merom may not be as big of an upgrade to Yonah as Conroe was to NetBurst, but the bottom line is that you get equal or better performance in every test without increasing cost or decreasing battery life. Owners of Core Duo laptops really have no reason to worry about upgrading for now, and waiting for the Santa Rosa platform before your next laptop upgrade seems reasonable. Those looking to purchase a new notebook on the other hand have no reason to avoid Core 2 Duo models, assuming pricing is consistent with what Intel is promising. There will be a delay of at least a few more weeks as we await availability, and testing and validation by laptop manufacturers may delay things a bit more, but within the next month or so you should be able to get a Core 2 laptop.

Answer 3

From what I've read, Core 2 Duo is just the latest, great model out. It's supposedly better in every way.

Answer 4

It can handle many more programs at once without one processor affecting the speed of the other. On the other hand, it
"combines" the speeds of the processors. It also enhances gaming experience for gamers and programs that run on high graphics.

Answer 5

you'll go loopy and waste a lot of time attempting to understand or evaluate those information. in basic terms %. the fastest CPU you are able to arise with the money for. (you should use their PassMark CPU ratings to judge them.)

Answer 6

Core Duo contains 151 million transistors, including the shared 2 MiB L2 cache. Yonah's execution core contains a 12 stage pipeline, forecasted to eventually be able to clock to 2.33–2.50 GHz of maximum frequency. The communication between the L2 cache and both execution cores is handled by an arbitration bus unit, which eliminates cache coherency traffic over the FSB, at the expense of raising the core-to-L2 latency from 10 clock cycles (in the Dothan Pentium M) to 14 clock cycles. The increase in clock frequency offsets the impact of the increased clock cycle latency. The power management components of the core features improved grained thermal control, as well as independent scaling of power between the two cores, resulting in very efficient management of power.

Core processors communicate with the system chipset over a 667 MT/s front side bus (FSB), up from 533 MT/s used by the fastest Pentium M.

Yonah is supported by the 945GM, 945PM, 945GT, 965GM, 965PM, and 965GT system chipsets. Core Duo and Core Solo use Socket M. Due to pin arrangement and new chipset functions are not compatible with any previous Pentium M motherboard.

The T2300E was later introduced as a replacement for the T2300. It has dropped support for Virtualization Technology. Early Intel specifications mistakenly claimed a halving of the Thermal Design Power.

New T2150 & T2250 have also appeared in OEM systems as a low-cost option with a lower 533Mhz FSB and no Virtualization Technology. No official data on these processors is yet available from Intel.

Core 2 is an eighth-generation x86 architecture microprocessor produced by Intel based on an all-new CPU architecture called the Intel Core microarchitecture, which is the successor of NetBurst microarchitecture that has powered most Intel processors since 2000. Core 2 also marks the retirement of Intel's Pentium brand name that has been used from 1993 and the reunion of Intel's notebook and desktop product lines since Pentium M was released apart from Pentium 4 in 2003.

The first wave of Core 2 processors was officially released on July 27, 2006. Like the Intel Core processors that they supersede, the Core 2 brand is subdivided into Duo (dual-core), Extreme (high-end) and Solo (single-core) models, and a confirmed Quad (quad-core) model is on the way.

Unlike NetBurst-based processors, such as the Pentium 4 and Pentium D, Core 2 does not stress designs based on extremely high clock speeds but rather improvements on other CPU features, including cache efficiency and number of cores. The power consumption of these processors is much lower than the Pentium desktop line of products. With a TDP of only 65 W, Core 2 has a significantly lower power consumption compared to its predecessor desktop chip the (Intel code named processor known as) Prescott's with a TDP of 130 W.

Intel Core 2 processors feature EM64T, Virtualization Technology, Execute Disable Bit, and SSSE3. The release also introduced LaGrande Technology, Enhanced SpeedStep Technology, and Active Management Technology (iAMT2).

The first Intel Core 2 Duo processor cores, codenamed Conroe, were launched on 27 July 2006. These processors are built on a 65 nm process and are intended for desktops, replacing the Pentium 4 and Pentium D. Intel has claimed that Conroe provides 40% more performance at 40% less power compared to the Pentium D. All Conroe processors have 4 MB L2 cache, however the E6300 and E6400 versions have half of their cache disabled, hence they only have 2 MB of usable L2 cache.

The lower end E6300 (1.86 GHz) and E6400 (2.13 GHz), both with a 1066MT/s FSB, were released on July 27, 2006. Traditionally, CPUs of the same family with less cache simply have the unavailable cache disabled (this allows parts that fail quality control to be sold at a lower rating). At launch time, Intel's prices for the Core 2 Duo E6300 and E6400 processors were $183 USD and $224 USD each in quantities of 1000. Conroe CPUs have an enormous value with their overclocking capabilities, the 1.86 GHz model has been shown to overclock to over 3.0 GHz with a good motherboard supporting high FSB speeds. In these reports, an overclocked Allendale 1.86 GHz was shown to edge out the Core 2 Extreme in certain benchmarks. According to well respected reviews, the E6300 and E6400 only suffers on average 3.5% because of the smaller L2 cache size. With the higher overclock of the two processors, enthusiasts can easily make up the 3.5% percent by overclocking further than its higher end Conroe cousins. However, the low multiplier on these two lowerend chips requires a very high FSB to reach high speeds, which few motherboards support.

The higher end Conroe processors are labeled as the E6600 and E6700 Core 2 Duo models, with the E6600 clocked at 2.4 GHz and the E6700 clocked at 2.67 GHz. 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 X2 Series), which were, until this latest Intel release, the fastest CPUs available, and the vanilla Conroe boasts much faster performance. Overclocking results show that the E6700 and E6600 are stable when overclocked to 4 GHz with air cooling and 5.4 GHz with liquid nitrogen cooling, despite having locked multipliers.

At launch time, Intel's prices for the Core 2 Duo E6600 and E6700 processors were $316 USD and $530 USD each in quantities of 1000.

Answer 7

I think they are the same thing. It's just core2 duo. The previous ones were pentium d (dual core).

Answer 8

faster, more efficient can't handle more programs running simultaneously..
