Intel SU2300 vs SU4100, much difference?

[Maximilian]

SU2300 - Dual core celeron
1.2ghz
1mb cache
800mhz FSB

SU4100 - Dual core pentium
1.3ghz
2mb cache
800mhz FSB

Is the core architecture cache sensitive? will that 1mb of cache make a big difference between these two cpu's?

Whether it is worth it really depends on the price difference. Neither one is going to be fast, but both will be adequate for a number of tasks.

The Core architecture is cache sensitive. This is the kind of difference you can expect: http://www.anandtech.com/bench/default.aspx?p=65&p2=67

But that is at 2.2ghz. These are nearly half that speed, so the difference should be less pronounced.

Personally, I think it is worth waiting for Arrandale and getting these things with Turbo mode.

The % differences would be comparable, neither any more nor any less pronounced.

The fact both of those chips run at 2.2 GHz is to equivocate as much as possible. They are basically the same exact chip, except one has half the cache. Likewise the SU2300 and S4100 are similar chips, with the major difference being one having half the cache. But in this case, the chip with more cache also has a higher clock speed, and thus this will add to its performance advantage.

No, the percent difference would be less, because cache is not as limiting at 1.2ghz. You can also look at it the other way, where people who bought 2mb cache chips and overclocked them to 3ghz+ were getting much worse performance/clock than E6000 series, despite having similar performance/clock in the 2ghz range.

That shouldn't be true, as cpus are overclocked, so is L2 cache, removing that bottleneck to an extent. You could be right but I'm almost certain cache differences produce a repeatable percent difference between processors at different speeds.

A $miss @ 1 mhz doesnt really matter, the ram has ur information already.
A $miss @ 5 ghz matters a lot more, u gotta wait for many more clock cycles to get the info

Ah that looks fine, they both perform well enough given their specs. Just wanted to make sure i avoid any crippled cpu's like that old P4 celeron with 128kb cache.

So what laptop are you thinking of buying?

Im not sure, i want a netbook, but one with more power. As far as im concerned anything 11.6" or under is a netbook to me so im looking at the acer 1810tz and the hp pavilion dm1, both can be pre ordered here in the UK.
