A computer geek friend of mine suggested that I buy nothing less than a dual core processor, and a quad core processor if I could afford it, because of the speed and ability to run multiple programs at once. If you've ever had the problem of your computer freezing because you're trying to use Paint Shop Pro, keep five different browser windows open and start up a Windows Excel spreadsheet, it's because your computer processor isn't powerful enough for every program that you're trying to run at once. So when I hunted for a new laptop last weekend, I refused to look at any computer that didn't have at least a dual core processor. But what was the difference between theIntel Pentium Dual Core T4300 and the Intel Core 2 Duo T6600?
The Intel Pentium Dual Core T4300 is a low-cost, 64-bit microprocessor. The Intel Pentium Dual Core T4300 is the economy version of the more expensive Intel Core 2 Duo T6600. The Intel Pentium Dual Core T4300 is just a little slower with a frequency of 2.1 gHz compared to 2.4 GHz. They both use quad data rate transfer and have an effective front side bus speed of 800 MHz. But the clock multiplier is a little slower on the Intel Pentium Dual Core T4300 at 10.5 executed instructions per cycle versus 11 for the Intel Core 2 Duo T6600. Both processors have a level 1 cache size of 128 KB, but the Intel Pentium Dual Core T4300 only has a 1 MB Level 2 cache versus a 2 MB Level 2 cache for the Intel Core 2 Duo T6600. The smaller Level 2 cache size is also going to affect the speed and performance of the CPU.
Although there's no question that the Intel Core 2 Duo T6600 would give me better processor performance, I chose the HP laptop with the Intel Pentium Dual-Core T4300 because of the affordable price, a full $100 cheaper. I don't watch or edit HD or Blue-Ray videos on my computer, nor am I into extreme online gaming that would require a more powerful or faster CPU.
