Pentium dual core T2080(1.73GHz/1MB) performance?

Hey guys, I was thinking about buying a dv6000t and I noticed a Pentium T2080 as one of the upgrades. So I'm wondering has anyone know the performance of this cpu compared to a Core duo? From what have heard the performance is like a dual core Celeron M, but that was off newegg.

I'm also curious about the heat and battery life, when I first saw it I thought it was a low clocked dual core Pentium 4 so I thought I should stay away like a plague. But now I'm thinking its something that Intel is making for a budget dual core cpu.

 

There is no such thing as a dual core Celerom M...

The Pentium T2080 is simply a 1.73GHz Core Duo chip with the cache halved.

Performance would be a little bit lower than current Core processors, but it shouldn't make a big difference, unless you're gaming or editing videos and the like.

 

The T2080 is one of the dual core variants which Intel produces but, judging by the lack of info on its website, doesn't know exists. There's a useful description at the bottom of this Wikipedia page. The slightly slower T2060 has been around for several months and the only difference between it and other Core Duo CPUs is that has only 1MB of cache. Unlike the Celeron CPUs, the T2060 normally has working speedstep.

There's a review here of a Toshiba A135 with the T2080. Having only 1MB cache does slow performance a little, but that is a trade-off, provided the price is right.

So what is Intel doing. They obviously collected a pile of chips which were OK except for having less than 2MB of working cache. So rather than chuck them out, it makes sense to sell them as a lower priced product with only 1MB cache. Or maybe they are perfectly good Core Duo CPUs being crippled and sold cheap in order to give AMD a hard time at the budget end of the market.

Better to not think of it as a dual core Celeron but a slightly crippled Core Duo CPU. The review noted above was favourable about the heat aspect.

When I said a dual core Celeron M it was in terms of performance (it was actually hes words not mine) but it did make sense since they both had 1MB of cache.

Thanks for the fast replys though, the exact info I was looking for.

 

Both the Pentium Dual-Core T2060 and recently introduced T2080 aren't crippled versions of Intel's Core Duo or Core 2 Duo series processors, with L2 Cache reduced to 1MB. Other key differences are:

1) The T2060 / T2080 are not classified under Intel's Centrino Duo Mobile Technology. Rather they are part of Intel's Pentium dual-core processor family (Intel had announced that they were dropping the Pentium branding, but here it is resurrected - don't know why).
2) The T2060 / T2080 operate with a Front Side Bus frequency of 533MHz. All the performance dual-core processors in the Centrino Duo Mobile Technology family operate at a FSB frequency of 667MHz.
3) Also, the T2060 / T2080 do not support Intel Virtualization Technology and Intel 64, 64-bit computing on Intel architecture; both features are prominently supported on all performance dual-core processors in the Centrino Duo Mobile Technology family.

To get a good overview of the Pentium dual-core processor family, you can go to the following website: http://asia.cnet.com/reviews/pcperipherals/0,39051168,61998152-8,00.htm

This website will give you more info than what's on Intel's own website.

Good luck with your purchase!

hmmm yes they are not centrino-rated CPUs but i cant see anything in that article which states they are not Core Duo or C2D CPUs that have been trimmed down. a core duo or c2d doesnt have to be a centrino, that is just a rating system Intel developed.

 

Intel poured millions and millions of dollars into promoting the Pentium brand name over the years and most computer customers know what a Pentium is. It was actually quite a good idea on Intel's end to make a new processor using that name.

As far as buying a Pentium Dual-Core T2080, do yourself a favor; spend another $50 and get the T2350, which has a 2MB L2 cache and a faster 1.86GHz clockspeed.

 

from the Toshiba A135 review I have to say that this CPU is not bad at all as it's only 1second behind the C2D 1.66Ghz (with 2MB cache) on the Pi test.

 

You got it backwards, T2080 is similar to Pentium E2140 and E2160 desktop processors, outperforms T2350 in many things, multimedia/SSE performance is like twice as high. T2080 lines up somewhere between Core2Duo and Turion X2 performance wise.

 

Wait so 1.7GHz 533MHz bus 1mb cache > 1.86GHz 533MHz bus 2mb cache?

Where did you get ur information from if I may ask?

 

It also depends on the motherboard and how it handles stuff

 

The E2140/E2160 are Conroes, while the T2060/T2080 are truncated Yonahs. Even with the desktop/mobile platform difference aside, the T2060/80 is not even of C2D architecture. The only thing they share with the E2140/60 is the budget branding.
