Intel's Core i7 870 & i5 750, Lynnfield: Harder, Better, Faster Stronger

SYSMark 2007 Performance
Our journey starts with SYSMark 2007, the only all-encompassing performance suite in our review today. The idea here is simple: one benchmark to indicate the overall performance of your machine.
I already spoiled the surprise and gave out the SYSMark data earlier, but this should put things in perspective. See how the Core i7 870 and Core i5 750 fit nicely in between the Core i7 920 and 975? Yeah, that's because pretty much anything below the 975 doesn't make sense anymore thanks to Lynnfield.
Guess what else doesn't make sense anymore? AMD's pricing on the Phenom II X4 965 BE. The 965 BE is priced at $245 while the i5 750 is a $196 processor. The 750 is about 6% faster here. AMD will need to adjust its prices downward after this.
The standings move around a bit in the individual SYSMark tests, but the bottom line remains: the Core i5 750, despite lacking Hyper Threading, is worthy.

well i have the better model i5 750 1156 socket gaming score is 5.9 on basic 500 gb hd 7200 with a ssd it hit 7.9 on a gigabyte GA-P55A-UD6 12gb ram. as for the pricecost was cheep intel (R)quad core (TM) i5 750 @2.66 GHz 2.67GHz cost around £100 mobo cost me £100 i though it is a very cheep upgrade considering price i wood like to here what score any Pehnom II X4 965 hit

The article itself is good. But Why on earth compare a standard clocked CPU (AMD) against overclocked ones (Intel). Makes no objective sense att all. I's like having a car test between a standard car and a tuned racecar. Of course the racecar will win in performance. The overclock results shouldn't be there at all. Maybe as a remark that tell what will happen if one would like to overclock. Looks rather unfair and biased.So... why??

All I saw in this article is comparison of CPUs in their stock configuration. What's wrong with that?Bozo Galora - Friday, September 11, 2009 - link
I must say this was a very good logical coherent review with just about all the info one would requireGood job - I had no intention of getting one of these, but now I may change my mind

http://www.intel.com/support/processors/sb/CS-0299...">http://www.intel.com/support/processors/sb/CS-0299...According to Intel...
Core i7 870:
5/4/2/2
Core i7 860:
5/4/1/1/
Core i5 750:
4/4/1/1
So the i7 870 has higher Turbo mode for 3 and 4 cores than 860 does.

Yeah and that means that the OC numbers for the 750 with Turbo don't make sense. For example 4160 / 160 = 26 which would be a Turbo of 6 BCLK.Same thing for the 860 OC 3C/4C Turbo number.
Am I missing something?

Its likely Anand has ES versions or such which allows multiplier adjustments. But at stock, the linked speeds are the Turbo Boost grades.Nich0 - Friday, September 11, 2009 - link
Yeah obviously I am not disputing the stock OC with Turbo enabled (that sounds weird: stock OC?), ie 160*20= 3200, but just what it means in terms of Turbo: it 'should' read 3.36 for 3/4C and 3.84 for 1/2C if the 1/1/4/4 Turbo spec is correct.rdkone - Thursday, September 10, 2009 - link
I don't like the fact that the BCLK directly and synchronously communicates with PCIe buss, thus affecting the videocard negatively (among other PCIe cards)... This is like overclocking years ago whereas the PCI bus would be affected in the same way and causing headaches... This is a major issue I feel for those wanting to push a fairly big overclock on these CPU's... Intel screwed the pooch for us overclockers I feel... Just more justification to limp along with my core 2 quad at 4.1Ghz rock solid... Like others have said, is funny how the articles don't show older CPU overclocks against all this new garb... In the past they used to... But that hurts sales : )SnowleopardPC - Thursday, September 10, 2009 - link
Ok, so what type of boost do I get over a Q6600 with 8gb of ram and windows 7 64?Is it worth upgrading or waiting for that 6 core 32nm to come out next year?
To upgrade to any of these I will need to replace a motherboard and ram with the processor.
