So some quick i5 or i7 advice? Return the i5 for i7.

@double07, it looks like your disk score is very low and that would hold your overall score down. The other numbers look about right.
I think, I know why my disc number is low. I just discovered that mine SF3 came with disc encryption on. I don't remember turning that on? I am disabling it as we speak. I am sure this have significant impact on disc performance but not yet proven.

Really would like to know if SP3 is faster without disk encryption. On mine it is on too since first start.
as an electrical engineer, I'd say microsoft made a bad decision to put i7 in it. but from business stand point of view, it may be right, for most of the people, the specs in paper talks. as an end user, if you want the performance for the money, i5 won hands down. if you consider upgrade it next year, i7 may have better resell value. I don't even expect the "burst performance", it really didn't show the advantage.
As a Computer Engineer id say they made the traditional tradeoffs that must be made on leading devices. Every Laptop ever made is a tradeoff between performance, heat, capacities, size and weight tablets and hybrids are no different.
when the capabilities of the 2 systems were trimmed to the same level, the trade off has gone too far. it's not that hard to figure that out.
.Disabled the disc encryption and reboot. I did PassMark test, the Disc Mark now score at 3098.
I'll wait for the complete analysis and tuning before making a final judgment, it might be a bit presumptive at this point. This appears to be firmware settings and changeable.
Intel engineers built the i5 for x performance @ 15w TDP and the i7 for x+y performance @ 15w TDP. If you throttle by z percent I'd still expect a y overall difference in performance. The Surface will dissipate w watts whether it has an i5 or i7 they are the same physical size. To say the i7 dissipates more heat than the i5 is to say that it violates the 15w TDP spec.
The i7 achieves its y performance gain even though it has a lower starting clock rate (1.7 vs 1.9) thru having larger on chip cache and other design enhancements.

Will disable disk encryption now and take some benchmarks before and after and post it here. think about an hour or so

SP3, Core i5, 8 GB RAM
With disk encryption:
Stopped Disk Encryption, did a restart and testet again
Without disk encryption
Will do now a passmark test again.
