What is the Fastest CPU supported by Vostro 1500?

So I have a 3 year old Vostro 1500 with T5470 (1.6Ghz), and it's starting to show its age... I'm thinking of adding some extra life to it and doing a CPU upgrade to the best possible CPU. So I'm just wondering what's the fastest CPU the Vostro 1500 will still support? Is it the T9300, or something higher?

 

The fastest = the most expensive in its segment.
T9300 is the best price-performance. And you can upgrade the HDD for better speed and snappiness too

 

Wow, it looks like you've went through many CPU upgrades, haha! By the way, I'm also reading up on the T8300, it's a lot cheaper (anywhere between $60-80 cheaper), but it's only 100Mhz slower and has 3MB Cache instead of 6MB... Wouldn't this "technically" be the best price-performance CPU? Just wondering.

 

I only have comparisson of T8100 and T9300 with wprime
(T8100 is 300MHz lower than T8300)

T8100 = 40.187 sec
T9300 = 33.562 sec

If you can get a T8300 with alot cheaper price than T9300, then yeah its the best.
Check out NBR marketplace or other forums, I got my T9300 for less than $125, and overall cpu upgrade cost ~$30 LOL

 

Wow, a T9300 for $125?!?!? Crazy... On eBay, even the T8300 are going for $165 after shipping. T9300 are easily over $200 on eBay.

I'll check out the Marketplace and see if anyone is willing to part with their T8300 or T9300 .

 

I upgraded my Vostro 1500 from a T5470 to the T8300 and it's noticeably faster now. Definitely worth it. After two and a half years, my 9 cell battery finally started to die. I picked up a Dell branded replacement from Ebay. I fully expect this laptop to last for years more.

 

Are you hitting 100% processor usage? If not, then upgrading the processor isn't going to do anything for you. More RAM or an SSD is going to be the way to go.
