This purchase was a step in my upgrade plan for an old PC i had in the office. Specs: E6600 is based on "Conroe" core and its key features are: - Socket 775 - 65 nm process - Actual clock speed is 2.4 GHz - 1066 MHz Bus - 4 MB Cache (2 MB per core) The old processor was Intel's Pentium D 820 (2.8 MHz, 800 Mhz, Hyper-threading enabled). I was using CrystalMark 2004 R3 as a benchmark and after upgrading processor only, there was a dramatic performance increase, from ~75K points to ~100K!! And this is with no overclocking! The reason i was upgrading is that my mainboard (ASUS P5LD2-VM SE) was not able to support any newer 45 nm CPU's (Wolfdale or Yorkfield), i.e. was limited by the Conroe family. When my search was filtered to 65 nm CPU's only, there were not many options left. First of all i really wanted to have a "full speed" 1066 MHz bus. This made my filter even more narrow and left E6??0 processors only. Among them were E6300 and E6400 which have 2 times less cache. Their older brothers, E6320 and E6420 had full 4 MBs of cache with core speeds of 1.86 and 2.13 GHz respectively. Next steps were E6600 and E6700 with clocks at 2.4 and 2.66. There is also an extreme edition, X6800, though upgrading to it would be too expensive against performance increase on an old machine. The supply on eBay was pretty limited for both of either E6600 or E6700, so I just started looking for a good offer, until finally found one. And that made me really happy. The processor can also be nicely overclocked, up to 3.0 GHz in my case, though lots of people report much more. Con's - no reallyRead full review
Intel Core 2 Duo processor family is designed to provide powerful energy-efficient performance. With Intel Core 2 Duo desktop processor you'll experience revolutionary performance, unbelievable system responsiveness and energy-efficiency second to none. And you won't have to worry it slows down for virus scan, multiple compute intensive programs, or multimedia downloads.
Verified purchase: Yes | Condition: Pre-owned
good processor, very stable, fast, overclocking posibilies, I recomended for those who want to have a good PC with few money
The Intel® Core™2 E6600 desktop processor combine the performance of the previous generation of desktop products with the power efficiencies of a low-power microarchitecture to enable smaller, quieter systems. The certain processor is 64-bit processor that maintains compatibility with IA-32 software. This processor supports several Advanced Technologies including the Execute Disable Bit, Intel® 64 Architecture, and Enhanced Intel SpeedStep® Technology and supports Intel® Virtualization Technology (Intel VT). With this Intel® Core™2 Duo desktop processor, you'll experience revolutionary performance, unbelievable system responsiveness, and energy-efficiency built in – up to 40% faster and over 40% more energy efficient. Intel® Core™2 Duo processors are the new brand name for next-generation energy-efficient performance desktop and mobile processors. The Intel® Core™2 processors for desktop and mobile computers are based on the Intel® Core™ microarchitecture, Intel's new industry-leading foundation for all mobile, desktop and server platforms moving forward. Compared to Pentium 4, Core Duo (not to be confused with Core 2 Duo) offers low power consumption, low waste heat and high performance per clock. This is almost an exact opposite to the Pentium 4 which used so much power that the ATX specification had to be modified to add more 12V rails, and produced so much heat that they often throttled and made reaching 4GHz almost impossible. Not only this, but clock for clock performance wasn't stellar – hence the need for higher clock speeds in the first place. Core 2 Duo is the next generation on from Core Duo. If it wasn't completely obvious, the "Duo" portion of the name indicates that these Core 2 Duo are dual-core processors. Unlike previous Pentium D processors, these use a shared Level 2 cache (2MB or 4MB depending on the processor). This can be dynamically allocated depending on the task being run. For instance, if running an application that isn't multi-threaded (i.e. can't take advantage of a second core), then the primary core would get the full 4MB of Level 2 cache. Having more Level 2 cache means that fewer requests need to be made to the system memory – one of the biggest causes of latency. So this makes E6600 one of the most powerful processors ever made introducing low latency and low power consumption. When idling, the Core 2 Duo E6600 will drop its multiplier from 9.0x (2.4 GHz) to 6.0x (1.6 GHz) to conserve power. With these power saving modes enabled, Core 2 Duo system conservs 17W of power (for example 186W to 169W) and rans about 5°F cooler than when power saving mode is disabled. This isn't much of a difference, really, as the "Conroe" architecture already is fairly efficient in terms of power consumption and heat production. In order to show the superiority of Core 2 Duo E6600, a CPU arithmetic test (SiSoft Sandra 2007) was conducted involving several processors. See carefully the results: Core 2 Duo E6600 (3.0 GHz)* -- 27690 !!!! Core 2 Duo E6600 (2.4 GHz) -- 22137 !!!! Core 2 Duo E6400 (2.13 GHz) -- 19738 Athlon64 FX-62 (3.0 GHz)* -- 21873 Athlon64 FX-62 (2.8 GHz) -- 20382 Athlon64 X2 4600+ (2.4 GHz) -- 17495 Athlon64 X2 4200+ (2.2 GHz) -- 15994 Athlon64 X2 3800+ (2.0 GHz) -- 14515 *overclocked processors sources: www.intel.com http://www.tigerdirect.com http://www.trustedreviews.com http://www.gamepc.com Regards, SpychroRead full review
As many people know, the Q6600 was the daddy of all quad core processors in the age of Core 2. The G0 stepping model was the best of them all and would easily overclock above 3ghz, some going as high as 3.7 or more. This is all well and good - the processor was a pretty voltage friendly chip that required a paultry 95W max power to run. Compare this with the Pentium 4 and D chips that preceded it running at between 80 and 100 for a single core and you realise the huge step forward that the Core 2 range brought in. That said, with Quad core processors only recently being implemented fully into games, their uses are still pretty limited. You will see no performance drop in a majority of situations by using an equivalent dual core. This is why i have always favoured the E6600 over the Q6600 - it gives the same power where it counts. As well as this, the E6600 is far more voltage friendly, accepting up to 1.5v rather than the quad's 1.3v. This makes overclocking it much easier and it keeps the temps down. Combine all this with the fact that you can pick one up for just 70 quid (around 2/3 of what you will pay for the quad) and it is a big bargain. The final plus for bargain hunters is that the conroe based E6600's are still compatable with the 680i series of boards, a firm favorite of overclockers for its price point, overclocking ability and SLi support.Read full review
