OcUK now selling e2180! Well when stock arrives.

[thumper]

anyone got any results from this chip and the asrock 4core board yet?
cheap 3ghz?

Hi all

I can also report that these chips clock very well! Had mine at 3ghz with stock volts (orthos stable). Once i get a better cooler i will push it futher but at the mo, its plenty fast enough compared to my old 4600X2.

So my advice is buy coz you wont be disappointed.

What kind of extra FPS are you getting? I have a 4600 X2 myself and have been thinking about jumping ship over to Intel and the C2D's look pretty awesome at the moment.

one thing to note is that the E21nn series does suffer the lack of l2 cache when playing UT3

interesting states, but it seems that with a good overclocke you can overcome the loss of cache.

Remember what we discovered about the impact of L2 cache on performance: you need around 20% more clocks to make up for a 2MB L2 deficit on Intel's CPUs, and about 35% to make up for a 3MB deficit.

 

[str]

From 1MB to 2MB there's a pretty hefty 12 - 13% increase in performance at 1.8GHz, but the difference from 2MB to 4MB is slightly more muted at 4 - 8.5%. An overall 20% increase in performance simply due to L2 cache size on Intel CPUs at 1.8GHz is impressive.

Overall 20% difference isn't too bad really.

We note the clock speed simply because the gap will only widen at higher clock speeds; faster CPUs are more data hungry and thus need larger caches to keep their execution units adequately fed.

Pure conjecture. Where is the test results to back up this claim?

In order to close the performance deficit, you'd have to run a Pentium Dual-Core at almost a 20% higher frequency than a Core 2 Duo E4000, and around a 35% higher frequency than a Core 2 Duo E6000 series processor.

That 35% to make up a 3MB deficit doesn't add up. The tests show a ~20% difference between 1MB and 4MB cache and they says clock speed scaling would make it a bigger percentage but they don't provide any facts just that statement with nothing to back it up so while it could be true until it's properly verified it's just fiction IMO.

at the moment they say the same, these are preliminary results...still another bit of info to add

What's interesting is that they arrive at this figure by underclocking a 4MB cache chip, rather than overclocking a 1MB cache chip which is what users do in reality. I think in a lot of cases once you get to 3GHz the graphics card is the limiting factor

Asrock board should be delivered today then the chip next week hopefully should be good. gonna drop some ddr2 into it and keep my 1950pro for the moment

 

[bandit]

so what have people managed to get on the stock coooler for the 2180?

 

[Going to Cali]

I've put mine straight to 3ghz with the stock HSF.
Haven't had any problems yet, but when the new braket arrives I'll be putting the Zalman 7000b copper cooler from my 754 system in. It should lower my temps and perhaps give me an extra .3ghz

 

[bandit]

what temps at 3ghz?

Hi

Well in current games i am gpu limited, but certainly in GRAW i notice around 5fps at least using this chip at 3ghz. I sold all my gear on the auction site and bought my current set up for less than what i sold!!!
