Comparison and Difference between DDR2 and DDR3 memory

Difference and Comparison between DDR2 and DDR3 memory

Most of the recent notebooks and computers of both AMD and Intel are coming up equipped with DDR2  and DDR3 memories. This FAQ should help you understand the difference in the DDR2 and DDR3  memories.

Q. Can I insert a DDR3 memory module in a motherboard designed for DDR2 memory ?

A. No, you can not insert DDR3 memory module in a motherboard designed for the DDR2 memory. They have different sockets and the pin outs.

Q. What are different speed grades of the DDR2 versus DDR3 memory available.
A. The DDR2 memory is available officially available in the speed range of 400 to 800 Megabits  per second. The DDR3 memory is officially available in the speed range of 800  to 1600 Megabits per second. Speeds higher than 800 Mbps in DDR and higher than 1600 in DDR3 are also available,  but they are not officially supported.

Q. How much is the real improvement in the memory throughput in DDR3 over DDR2

A. This is very good question. The actual throughput measurement involves the motherboard, CPU among other things and it makes the comparison difficult. However, there has not been any significant improvement in the performance between DDR2 and DDR3 even with  the marked increase in the frequency. It is only after DDR3-1333 that you start to see something real in terms of the improvement in the throughput. Various benchmarks have reported 5% to 1% improvements depending upon the memory configuration and the speed grades of the memory you are comparing.

Q. I heard that the Cache Latency of DDR3 memory is higher than that of the DDR2. And that this makes DDR3 memory slower than the DDR2 memory.

A. You are correct in that the Cache Latency of the DDR3 memory is higher than the DDR2 memory. Cache Latency is defined at the time between the issue of the read command from the processor and the time when the data from the memory actually becomes available. It is measures in the units of clock cycles. A higher cache latency in DDR3 means that it becomes slower. However, cache latency is not the only thing determining the overall performance and speed of the DDR3 memory. The higher speed of the DDR3 memory more than makes up the issue of the cache latency.

Q. How about power consumptions ? Which of these two memories consume lower power ?

A. DDR3 memory was designed with power consumption in mind. DDR3 consumes substantially lower power than the DDR2 memory. This especially helps the notebooks that are supposed to work on batteries and the battery life is a concern.

Q. What technological challenge is presented in the architecture and design of the DDR3 memory.

A. Since DDR3 memory works much faster than the DDR2 memory, there are Signal Integrity  challenges to keep the memory part running at much higher frequency. Also the DDR3 memory has been designed to work at lower voltage level. Lower voltage means that a small amount of noise in the power supply rail can lead to error and failure. This is manifested in terms of system hanging. The designers using DDR3 must analyze the platform and the system motherboard to ensure that it stays robust under all conditions of temperature and voltage variations.

About 2012 Honda Accord

The Accord series from Honda has been making waves in the market for the past few years.

There are several trim level versions to choose from though such as the LX, LX-P, SE, EX, and EX-L versions.

Onto the mechanical aspect, the 2012 Honda Accord will feature the same mechanical setting as with the 2011 model. However, as the eighth generation in the series, then the manufacturer are looking to add newer components. The base engine option is a 2.4-liter four-cylinder engine that will bring in up to 177 horsepower and is available for the SE,LX, and XL-P models. There is also another version of the same engine for the EX and EX-L trims that bring in a higher 190 horsepower and paired with an option between five-speed automatic and five-speed manual transmissions.

The changes made on the design and engineering for the 2012 Honda Accord pays off in terms of fuel economy rating. This model therefore offers decent performance in EPA rating to give it better mileage. The ones equipped with a manual transmission is rated at 22 mpg on the city and 31 mpg on the highway. Those on automatic performed better at 23 mpg on the city and 34 mpg on the highway.

Pro’s of 2012 Honda Accord

*Decent fuel economy rating;

*Several trim level choices;

*Powerful engine;

*Great overall performance.

Con’s of 2012 Honda Accord

*Lacks visual appeal.

Pricing Details

The current estimate given for the price range on the 2012 Honda Accord model is somewhere between $23,000 to $33,000. Thus, it will remain as competitive as the past models have been to ensure that it will retain its sales performance despite the arrival of newer models. The base model equipped with a four-cylinder engine will start at $23,000. Meanwhile, the EX-L model is expected to reach no less than $30,000. The EX model, which is equipped with a 190-hp four cylinder engine and automatic transmission will start at a $26,000 price tag.

The Bottom Line

The 2012 Honda Accord is an excellent option for those who wanted to get a car that is generously sized with maximum capability, but would not mind if the cutting edge design and exterior styling is somewhat compromised in the process.

The CR-V series from Honda has been in the market for a long time. So, when they decided to release the 2012 Honda CR-V model, the engineers were hard at work to recapture the attention of its customer base and regain its position as one of the sales leaders in the market. In these times of dour economy, the challenge is much tougher than it looks, so make sure to see more details about this new edition below.

Therefore, this model remains competitive within its class that combines well with the improved handling system. However, the five-speed automatic transmission is the sole transmission option available, which could eventually turn out to be one of the model’s major drawbacks. Thankfully, the fuel economy rating is quite impressive with an average of 21 mpg on the city and 28 mpg on the highway for those equipped with a front-wheel drive. Such rating is indeed among the best in its class.
