P8600 vs T9300 on a P-6831FX, worth the difference?

would it be extremely preferential to get a t9300 on this lappy as opposed to a p8600? this price difference is nearly 100 dollars and im wondering what the major upgrade is with the t9300, i know it has 3 more mb of cache and its 2.5ghz as opposed to 2.4, but what else?

 

Are you talking about the t8300 vs the t9300?

Because you cant use the p8600 in the 6831. (Wrong generation of CPU)


But if your looking at the t8300/t9300. The t9300 is nice, but if you want great preformance for not a whole lot of investment then the t8300 is deffinatly the way to go

 

The P8600 is a P socket but it still wouldnt work?

 

Correct. I forget exactly why, something to do with the pin number staying the same which is why they're both Socket P, but the orientation of the pins being different between Santa Rosa platform CPUs and Montevnia platform CPUs.

That's off the top of my head and could be wrong though, anyone better informed correct me if that's the case.

 

alright, i think i found the equivalent of the p8600 in the T7700, how does that stack up to a t9300?

 

T8300 is the one your looking for

you could go with the t7700, but your better off with the t8300 due to the die shrink and more efficent operation. Plus you would save on heat due to the wonders that the t8300/t9300 can reach with undervolting.

But to answer your base question. No your not going to notice a difference between 2.4ghz and 2.5gHz. The only thing that will show a difference will be artifical benchmarks, in real worl preformance 100mHz isnt going to be noticable to humans when your already talking of speeds like this.

As to why the new CPU's dont work... yes they both use the P socket but the newer ones have an extra pin I believe 378pins vs 379 pins, but i'll have to check again to be sure

 

Socket P Meroms and Penryns have the same pin-package and the same pin-out. So, they are interchangeable, but most SR system BIOSs won't recognise the new Penryn-Refresh series, and even if they do, the CPUs would run at a reduced FSB, as 965 chipsets are not instructed to run at 266MHz FSB.

A better CPU than the T7700 will be the T8300.

Basically Merom vs Penryn, newer/efficient instructions (SSE4) in penryn, newer fabrication materials used in penryn, 45nm technology -> shrinked transistors, more cache, etc etc.

Penryns are better. Now all cpu-intensive applications are not able to use the cache. Most only benefit from the CPU frequency. And larger cache, more latency, which almost negates whatever real-world performance boost is provided due to the increased cache size.

So, sticking to the Penryns will be better, and the T8300 is a good CPU and most T8300s out there undervolt well.

 

Thanks for all the help, ill probably get a t8300 soon, although i wonder how much my machine is actually being bottlenecked by a t5450?

 

I can tell you this: The T5450 and/or T5550 are certainly no slouches, but when I moved up to the x7800, even at stock speed, it was like a whole new machine! And the T8300 isn't too far behind a stock x7800 performance wise.

 

I see the t5450 going around 50 bucks on ebay which kinda gives me a negative image of it. Plus it seems like everyone upgrading to a processor past 2.0 is getting much better results especially in the realm of gaming.

 

Yea. The 5450 is priced pretty cheap, and is clocked pretty low, but think about it this way, the T5450 stomps pretty much every mobile CPU AMD has out currently. It's definitely not a bad performer, but as you have figured out, there are certainly better to be had.

 

now all that remains is for me to get a good deal off the t8300.

 

this is all i can find on ebay

I was researching whether upgrading the stock CPU is worth it. I'm looking to get some performance boosts in Warhammer Online. Right now, stock, it runs fairly well at balanced settings at a high resolution. It lags a bit though during big RvR battles. Maybe upgrading the CPU will help.
