Recently, Intel slated its latest lowest priced 45nm product to market in name of E5×00. This is the chip that would be destined to arouse every cost-conscious customer’s eyeball. Intel CPSs had been enjoying good headroom in thanks to their more advanced manufacturing processes. Since 2006, this advantage became much larger as AMD ran into an eventual frequency wall due to its rather elder all-time-around architecture.

Especially after Intel introduced the greatest Core micro architecture in 2006, almost each and every Intel processor, regardless of what label they got stuck upon, can all boost up directly a healthy 1GHz over its slated frequency, and as producing process matures, that grows much more. Thus it brought upon a revolution to the low-end market with huge impact upon the whole system’s performance. No longer comes back the days when cheap chips meaning chips burnt and slow.

Thanks to Intel, the hero, computer builders today can have such a great variety of choices in CPUs which is just unimaginable two years ago. Any PC today can outperform the best ones a year before. That is just crazy! Yet ,it is true. E21×0 got this proven. E1×00 got the theory sealed as a fact. And .since Intel had been switching all its products to its latest 45nm manufacturing process, you may wonder when the low-end CPUs will get 45nm refreshment.

And the answer is now. The small chip that will become the talk of the town in coming months, a brand new low-end processor from Intel, utilising 45 nanometer technology, in the name of "Intel Pentium Dual Core E5×00", is finally here. If you got confused by its name, just remember the shorter title it carries "A replacement while enhancement to E21×0".

Ladies and gentlemen, E5200, from Intel.

Although frequency defaulted at 2.5GHz with the same 800FSB as E2×00 had, E5200 is equipped with a very high multiplier, 12.5, which guarantees the potential for its overclocking headroom, and the low core voltage also provides more chances to unleash the chip’s real power. Latest version of CPU-Z can already detect the new CPU accurately while Core Temp still obviously lacking information.

Compared with E21×0, 5200 has twice the L2 cache, a great improvement thanks to the 45nm process. All 5×00 inherit the common TDP of 65W applied almost to all medium Intel CPUs, but according to CPU-Z, it obviously enjoys a lowered core voltage, thus that will secure the fact that this 45nm derivative will consume much less energy than its 65nm counterpart.

The test focus only upon the overclock possibility, leaving out the detailed performance comparison. If E5200 can be overclocked to the level of what E21×0 could manage, the chip will definitely be empowered enough to well demonstrate the power of 45nm Penryn family.

Setup:

P5K PRO P35 Chipset

G.SKILL 2GB*2 DDR2 800 OC 1066

E5200 2.5GHz

AMD ATI Radeon HD4850

Default Intel Heatsink

So first of all, find out the voltage to power up 3.6GHz for daily use. 1.368v set in BIOS.

55

Then, search for the voltage to power up 4GHz.

7  781 23

Seems like Everest is having some problem with the new CPU. Never mind.

Have a look at how it helps 4850 perform under 3DMark 06.

After a long test-run, the lowest steady voltage for default 2.5GHz operating is found.

At 1.1125v, E5200 can operate perfectly. Really stunning!
