Intel processor questions t7600 and the t8300

[bass1175]

While researching for possible t60 upgrades I learned that these three t7200 7400 7600 are my best bet with the first two being better options. My friend was also on his laptop and decided to research his processor which was the t8300. What surprised me is how it seemed as a higher model with faster processing power, yet was much cheaper in the market then the t7300 or the t7600. Can someone fill me in as to why the major difference in price and why the t7600 would be more then the t8300.

The T7600 is the top of the line Socket M, 667MHz bus Core 2 Duo. It's the best processor for many machines like the T60, Z61t or Z61m, R60, etc. (and many non-ThinkPads, too). Which makes it very desirable.

The T8300 is a solid Socket P performer, but not the top of the line at all for 800MHz bus Core 2 Duo machines, like the T61 or R61. It was probably also introduced at a lower cost than the T7600 ever sold.

Intel shows the T7600 list as $619 and the T8300 shows as $241.

Supply and demand.

Thanks for your insight under, one more thing I used this small software called Super Pi for windows that calculates the processors speed, so I compared my currently installed t2500 to my buddies t8300 and the results were very close, only 1 second off on most test.
Both were on max performance. Is this normal?

hi there

might wana try this version ,,, to compare (mili'sec version)

Thanks for the updated version, the tests gave the same results on my machine and will test my partners processor later on this evening. Should there be a huge difference between the t2500 and his t8300? I made sure that nothing with occupying the processor on both machines. I also made sure both were running on max performance and not max battery while both were plugged in.

With this software my 512kb were processed at 12.860 seconds and the 1mb at 32.641s.

Would love to see other reading if anyone is interested to compare your processor with my t2500. Most interestingly how the t7000 would compare.

T7200: 512kb @11.750s, 1mb @26.640s

My guess is that the extra 2MB cache start making the difference at some point.

T60p w/T7600 C2D cpu;

512KB --> 10.000s
1MB --> 22.454s

This is with your T7600 or with a T7200? That's a strangely big difference if it is the latter.

T7600! Sorry about that, I mistyped! (I corrected the post.)

Exactement. Just like you would think that the Core 2 Extreme X9100, which runs at 3.06GHz, is listed at a much higher price than the T9900 Core 2 Duo, which also runs at 3.06GHz and has the same amount of cache than does the X9100.

However, the T9900 is the technologically more advanced CPU for a couple of reasons. For one, it runs cooler at 35W, where as the X9100's TDP is 45W. The X9100 also does not have Trusted Execution Technology, which the T9900 does support.

Then there is the name...Core 2 Extreme. Wow. This must be something very special. Well yes, it was, as it came out almost two years before the T9900 did, which is "only" a Core 2 Duo.

If the X9100 Core 2 Extreme supported out-of-the-box overclocking, which "Extreme" processors often do, that would be a different story, but it doesn't. It's all marketing and timing.
