£50 wow. Thats a bargain. Especially if it overclocks even remotely like the rest of the C2D family. Also the final nail in the coffin for AMD's current line up.

If it comes out at £30 i'll buy one just to see how well it clocks.
and there was me about to build a rig around an x2 3800, or 5600 depending on funds. bah, humbug. more choices :(
Some sites say it gives the E4300 a run for its money, for £50 I will buy one for my second rig

Should clock well, good for 3.2Ghz with DDR2 800 without pushing the memory.
surely going from 1.6 to 3.2 would have issues? thats like double :surprised:
Not really, the silicon design is mostly the same, just with differing cache. But the 1Mb cache will be a limitation compared to say the E6600 in large complex algorithms used by modern games, video transcoding and the like.
No it won't. My 3800 only has 512k cache - game performance is near identical to equivalent 1mb cache processors, and far better than 2-4mb pentiums.Quote:

Don't think so in the slightest to be honest :p Core 2 Duo's advantage is mostly explained by 4 IPC to X2's 3. Better mem-prefetch is in addition to that, but the way that's improved actually means you could get away with less cache - it's the way it's fetched, not the volume of cache, that's made the difference.
Sure, more cache provides some small benefits in some circumstances, but in the volumes we're talking about it's not going to be limiting, given such tasks fit perfectly fine with 512k cache of AMDs chips.
I agree, and you could get away with less cache in x86 compiled apps (which most people tend to use these days), however x86_64 compilers will make use of more optimisations because they are aware that x86_64 CPUs have heaps more registers and cache.
It's hard to say with absolute certainty of course until someone writes performance benchmarks that are designed to test cache. But I am fairly confidant that Intel gets away with it's lower memory bandwidth thanks partially due to it's larger cache on top of better modern pre-fetching hardware and software. :)
The point about registers is interesting. There aren't all that many new anyway, but some of the earlier results comparing AMD X2 to Core 2 Duo showed that there was a bigger boost in performance for the X2 going from 32 to 64bit than doing the same with the Core 2 Duo.
What was actually happening had nothing to do with cache size - even 64bit intructions fit fine within 512k cache, but the length of them actually means you can't fit so many in the 16bit instruction fetch/predecode of core 2 duo, meaning it dropped back to 3 IPC.
So infact the cache size has no special importance for 64 bit processing, especially not L2 cache, but infact it's the width of the instruction fetch/predecode that's important, and in this regard the E2140 should be identical to the E6600.

100% overclock. Looks good. Stock cooling and everything.

Engineering samples are 99.99% of the time a lot better then the final product.
Take that with a pinch of salt.
Can anyone here send a enote to Ebuyer and ask when the E2140 are coming in stock.
I dont have an account with them.

Ask for Mike Hunt. :)
hahaha.. Anyway, looks like a great chip to mess around with.. Bought my E4300 2 weeks ago, not really fearing the price drops (as I'd get 2 weeks of joy out of it!) but didn't really think they'd introduce something new that was that cheap and overclockable! I run my E4300 at 2.7ghz, which I'm sure would be easily obtainable with the new cpu. Oh well..
Now we just need a decent mATX for Intel Core 2 Duos :D
Was planning on X2 3600 and an Abit NF-M2 nView but I think I can wait a bit now :P
I was never that interested in the whole HTPC side of things, but if they keep coming out with cheap powerful components, I might as well have to take the plunge.. :S
On a side note, bought an alphacool res from ebuyer, turned up as B-Grade. Quick trip to saynoto0870.com and 10 minutes later I was off the phone with an advance replacement being sent out and a collection booked. Painless to be honest.Quote:
