t7500 TO T9300 UPGRADE real price...

I have chance for this upgrade in hp 8510p... What i s OK price to pay for that???

 

I wouldn't pay much for that, since T7500 is 2.2ghz / 4mb cache, and T9300 is only 2.4 ghz / 6mb cache.

if it's an upgrade option, i wouldn't pay more than $40-50 more for the extra 200mhz and 6mb cache personally. it's an improvement, but not really one worth more than $40-50 for the difference in my opinion

 

Agreed . . . the upgrade is not worth much in any situation.

The CPU is not a performance-limiting factor for the majority of applications. Your money is likely better spent on a faster hard drive/SSD and RAM.

 

The T9300 is 2.5GHz, not 2.4. It's also Penryn (45nm) rather than Merom (65nm) and thus should run somewhat cooler and contains an extra instruction set (SSE4.1).

According to notebookcheck, the difference between the two in benchmarks and CPU-bound applications varies between 20% and 35% depending on the application (usually closer to 20%). How much this is worth to you depends on what you are going to do with it. If you don't run any CPU-bound applications (few people do), then don't waste your time or your money. If you use them all the time, its value depends on how much time you'd save and how much this time is worth to you. I'd pay a bit less than $100 for this kind of upgrade, but that's just me -- you have to consider your own usage to determine the upgrade's value.

 

Thanks guys... Definitely 120euro is tooooo much- according to your posts... I also have chance to replace it with T8100 from mine other notebook for 0 euros... Mine target is less temps and silent machine not performance... T7500 is not so good for this...

 

The T8100 would be a good upgrade then; it will run cooler and have better battery life since it is built with newer 45nm technology. The performance difference between the T8100 and the T7500 will not be significant.

Note that by upgrading your CPU, you will likely void your warranty.

 

What is real price for whole 8510p (in very good conditions)...
T7500 2GB RAM, 160GB hard 1680x1050 screen...

 

it seems it was about 1k USD when sold recently by someone here........ but personally i wouldn't pay more than $750..

 

I've seen many people assert that 45 nm penryn runs cooler than 65 merom cpu. Does anyone have actual real world data to back this up? The only metric I have seen is that intel rates all T series cpus to same 35 watt tdp (heat output) regardless of frequency or manufacturing process.

 

Probably closer to $750 that $1000. It's not worth all that much nowadays unfortunately.

At stock, the difference isn't huge. But these Penryn CPUs undervolts really well. The top multiplier of my T8300 runs at under 0.9750V and at 23.7W peak power. I am also a 8510p owner.

 

Do the math.. a size shrink in processors but keeping the same clock speed almost always yields lower peak and average temps.

 

I am surprised- 750 dollars... I thought it is max 400 euros...
It is few years old machine...

 

My undervolted T5250 merom runs under 0.9750 volts as well

As I said, have you seen any emprical data to quantify that? Does the difference actually translate into even a single degree cooler chip (same task same frequency merom vs penryn)?

 

actually it was for 700 pounds which is about 1000... but u nver know.. depends on warranty left and all.
