Intel dual-core Wolfdale series base using 45nm process. These processors use a smaller silicon wafers for the core processors. Coupled with the power of a larger L2 vs. Conroe Core. Conroe Core only has 4MB of L2, while the Wolfdale or Intel Core 2 Duo 8000 series has a 6MB L2. Peryn Series has an additional special instructions for multimedia, with SSE4.1 instructions, while core Conroe still only provide SSE4.
In the picture below, left is the back of the E6600 is the right picture is the E8500. E8500 uses a smaller component than the E6600.
For this article described the best ability of the Intel E8000 processor. To test series processors use the highest with the E8500, 3.16Ghz speed (9.5X 333MHz). Internal FSB E8500 with 333MHz X 4 or 1333Mhz. E8500 Multiplier has a speed of up and down by 6 (idle) and 9.5x (load). When the processor is idle with EIST features enabled, the speed will decrease the speed of 2GHz, while full speed will reach 3.16Ghz.
Bus and multiplier on the E8500 processor is high, but the strength of internal and external bus has not been able to withstand the performance of processors for the overclock.
E8500 while requires mainboard with the latest chip-set. Like type P35, X38 or X48 with a new type of delayed release. in thethe figure below is the BIOS settings for the E8500 .

For benchmarks, comparable between the Core 2 Duo E8500 Wolfdale vs. Conroe E6600. 65nm Conroe core speed will be adjusted to match speed with the 3.16Ghz E8500 Wolfdale. The objective test at the same pace, to see the capabilities of the ratio of performance and power consumption of both processors.
All benchmark tests on the two processors do not change settings on the board, and only set by default, including setting Vcore to processors, including the settings to overclock processors.
Setting benchmark Procesor Speed Default speed
E8500 Overclock 4.0Ghz (9.5 x 422Mhz)
E8500 Default 3.16Ghz (9.5 x 333Mhz)
E6600 Overclock 3.16Ghz (9 x 352Mhz)
E6600 Default 2.4Ghz (9 x 266Mhz)
Below is an overclocked E8500. It takes only change the FSB from 333MHz to 422Mhz, make E8500 3.16Ghz reach 4.0 Ghz speed
Benchmark with CPUmark, between E6600 vs 8500 is not much different. E8500 is superior to a few points compared to E6600. With the same hardware capabilities, seen both processors have the performance did not differ. CPUmark only make an assessment of major systems such as memory, power supply and chip-sets. Looks a little above E6600 E8500 capabilities.
One test on SiSoft Sandra jangkal enough. Since E8500 has an additional SSE4 instructions for multimedia. So the test results appear different processor capabilities of the appearance of E8500 vs. E6600, and has a higher score than the E6600 although using the same speed.
There also appears on multimedia tests between integers with floating point, integer for multimedia capabilities of the processors E8500 through E6600. 2 score appear between the E6600 and E8500 with overclock at default speed is far different. While the number of Floating Point for a multimedia look at large.
Memory bandwidth is certainly related to the ability of memory. It is better to prepare a premium memory if you want to spur the E8500. Because the E8500 was able to generate bandwidth transfer above 7000MB / s with PC8500.
For PCMark 05, the second score processor processor looks not much different in speed 3.16Ghz. While the speed of memory appears from the E8500, because the processors are synchronous with FSB 1333Mhz FSB and a speed comparable to DDR2 PC8500.
In the test of multimedia applications with Vegas Pro 8 and TMPGEnc is very visible that the E8500 has the best score. Both video editing software can take advantage of dual core processors.
Test Vegas Pro to the same processor speed, E8500 9 seconds faster than the E6600 with overclock. When processor E8500 raced higher to 4GHz, the time can be saved to 48 seconds. Certainly not the number of seconds that will be analyzed, but the ability of E8500 processors are better able to handle multimedia applications.
Similarly, the test encoding software TMPGEnc from DivX to DVD format conversion. E8500 looks faster than the E6600 complete the encoding process.
Quite interesting to E8500 power consumption. For a computer system, it turns E8500 power consumption and performance was more efficient than the E6600.
Idle speed only by default 3.16Ghz E8500, only consumes 120W electric power. Power Consumption 10W E8500 looks lower than the E6600 with a lower speed. Even save up to 40W with the same speed of the overclock E8500 E6600 3.16Ghz.
When the processors are given half load or single-core, E8500 only requires 147W power to 3.16Ghz speed. Compared with the speed overclock E6600 3.16Ghz, even throwing power 186W. Differences both processors with the same speed to be much difference with 40W. Even when tests carried out for single and double core, E8500 4GHz driven up to speed consumes only 185W and 200W power, who uses a power like the E6600 with a lower speed 3.16Ghz
Overall, the performance ratio and the use of power is not yet capable E8500 Conroe Core matched by E6600.
There are 3 main abilities of the E8500 is a new instruction of SSE4.1 and a larger L2 cache, low power and the ability to overclock.
To SSE4.1 very well utilized for those who require encoding files such as DivX. Multimedia features make faster Penryn core mengulah multimedia data types. While we must wait for the features of the software that is able to take advantage of SSE4 instructions. E8500 L2 cache up to 6MB also larger so that it can help performance 3D games.
E8500 Wolfdale core code, it is more power efficient than the 65nm Conroe core. Multiplier processors will drop to 6x when idle make the processors work on the speed of 2GHz and more power efficient. So that users do not need to worry borosnya E8500 PC as a high-end PCs only require 100W at idle.
Overclock with E8500, is very good. With the premium board processor can be driven directly from 3.16Ghz up to 4GHz without special settings. The problem is when the processor is driven up to 4GHz, will have an impact on memory. If you want to work with overclocked E8500 processors, it's good to see also the ability of memory. Due to the lowest setting with the FSB above 400Mhz, need for speed grade DDR2 800Mhz or more.
