plz tell me which one is superior out of AMD Athlon II X2 250 VS E8400

More about : amd athlon 250 e8400

Superior how? The E8400 is clearly faster but it's also what, double the price? The athlon 2 has a much better platform (mobo upgradability) but if you want raw performance and dont care about that then the E8400 is the best option.

Any particular reason why you chose to compare those two cpus? Some details might help you get a better answer.

AMD Athlon II X2 250 Dual Core Processor Technical Specification:

* 2 Cores
* Speed: 3.0GHz
* Socket: AM3
* L2 Cache: 2MB (2 x 1MB)
* 4000MHz HyperTransport bus
* CMOS Technology: 45nm
* Virtualization Technology Support
* 64 bit support
* Heatsink and Fan included
* Voltage: 0.85V – 1.425V
* TDP: 65W

Intel® Core™2 Duo Desktop Processor E8400

Processor Specifications:
sSpec Number:SLAPL
CPU Speed:3 GHz
PCG:06
Bus Speed:1333 MHz
Bus/Core Ratio:9
L2 Cache Size:6 MB
L2 Cache Speed:3 GHz
Package Type:LGA775
Manufacturing Technology:45 nm
Core Stepping:C0
CPUID String:10676h
Thermal Design Power:65W
Thermal Specification:72.4°C
VID Voltage Range:0.85V – 1.3625V

The above specs shows that both are 3Ghz 2 core 45nm processors with comparable L2 Cache size.They operate at the very same rating of 65W
.85V-1.325V VID. Now what makes the difference and how.

Well they don't have anything like the same cache size, the E8400 has a lot more.
December 29, 2009 9:48:46 PM

Come on make that fast.............. I am waiting for your replay
December 29, 2009 9:55:03 PM

What that has to do with the 3Ghz assured??????? Is there any dependence?
December 29, 2009 9:56:36 PM

the e8400 will give you maybe 20% better frames per clock but the athlon ii 250 will give you maybe 100% better frames per dollar
December 29, 2009 10:01:35 PM

To be specific the AMD states 3Ghz at 2Mb L2 and Intel , the very same 3G for 6Mb L2 .

What???? I don't Understand

Now from http://www.pcstats.com/articleview.cfm?articleID=2427 I had this:

The Athlon II - Phenom without L3 Cache

Inside the AMD Athlon II processor is an architecture largely based on AMD's Phenom II 'Deneb', but optimized for dual-core processing. Instead of a large 6MB L3 cache that's shared between four cores, AMD has stripped out the L3 altogether and implemented a more sensible 2MB of L2 cache. Like the Phenom II, the L2 cache is split into a single megabyte of per core.

Sticking to a smaller cache size reduces overall cache latency, while increasing the size of a cache means greater hit rates, which reduce the amount of trips needed to fetch information from system memory. Having a large cache makes sense for quad-core processors, but for a dual-core processor like the Athlon II it would most likely be under utilized. Large caches also makes the CPU's silicon die larger, which increases the amount of power consumed and heat produced.

AMD has kept the size of the Athlon II processor small, about 117.5mm2. This is in part due to smaller cache sizes, but also thanks to moving to a 45nm manufacturing process. This makes the Athlon II X2 250 one of the smallest processors AMD has ever produced.

Now if those reviews prove right then why should we pay Intel almost twice for those 10% rather a Phenom or Athlon will do the job
December 29, 2009 10:37:50 PM

generally you shouldn't. the e8400 is overpriced. however it might make sense to buy it as a drop in upgrade for an aging socket 775 system
December 29, 2009 10:45:20 PM

Anyway a Great Thanks to all of you, and new info always awaited
December 29, 2009 11:34:13 PM

I have a Athlon 240 , the 2.8 ghz brother of the 250, and I really cant praise it enough, I have it clocked at 3.2 ghz and it is very cool and very stable and fast enough for anything I throw at it

Yeah the price for performance is weird for the Intel dual cores.... I have no idea how Intel is still keeping them at such high prices. One thing I can vouch for is I have an overclocked E8500 and this baby has never let me down on anything and I mostly game.

It shouldnt do, fact is it's still a very fast cpu for a lot of things.

But yes, dual cores are almost finished now and the prices for them on intels side are way higher than they should be.
