Im building a gaming pc.
Im planing to use i7 4771 that is Haswell.
But i was wondering is there any difference in the performance between Hasswell and Ivy bridge?
If there is,should i go with haswell or ivy bridge?
 
Haswell averages 10+% faster .... but Ivy overclocks about 6% more.

There is no point upgrading from sandy/ivy to haswell, however since you are building from scratch then you should go with Haswell.
 
Also the haswell motherboards (Z87 chipset) has some better features than the Z77 chipset).A lot off the new Z87 gaming boards have Intel's new Ethernet chip for better LAN connectivity, more USB 3.0 ports and all Sata 3 (6Gbs) ports.
 
Haswell is only about 5-10% faster than Ivy. You really wouldn't be able tell the difference. Honestly, for a gaming rig that won't be overclocking, I would pick up an Ivy Xeon 1230v2 then use the $85 saved for better GPU. For gaming, GPU matters more. If you think a CPU upgrade is in your future with this system, a Haswell 1230v3 could make sense. Here is a list of 1230 and 1240 in ivy and haswell with a 4771 for price comparison.

Since you are effectively locked out of overclocking with either I7-4771 or Xeon advice above (and thus I assume you don't want to overclock) - the you should definitely go Haswell.

There is little point going Ivy now, really, except for maybe a slightly lower price tag.
 


$85 isn't slightly lower price tag. :lol: For a gaming rig, that $85 is better served being put towards a better GPU than the Haswell solution would offer. At roughly that price difference, you could get a R9 280x/7970 over say a GTX 760. Or even a GTX 770 over the R9 280x/7970.
 


I disagree with such point of view. Besides extra performance (though 9% is a bit generous IMO), you also get additional value in extra features provided by series 8 chipper, like more USB3 and SATA6Gb/s ports and Haswell supports a couple of extra instruction sets and technologies which are unused now, but may be used later for extra performance boost.

It means that Haswell has a potential to become better with time, while Ivy is all done already.
 



We don't have any concrete info on that yet, it's more of a guesstimate now and there were some rumors that it actually may not be compatible.

Besides, I believe it is irrelevant too, since anyone who gets Haswell I7 now, won't really want to upgrade to Broadwell anyway.
 


I am going off what I read here at Tom's "News", was from Intel saying it would be compatible with the 1150 and released Q1 2014, not that long away really. But as you say this info may be a bit premature....
 
Yeah, no info. There was some supposedly leaked roadmap which featured a "Haswell Refresh" at Q2 2014 and Broadwell at Q4 2014 launched alongside Chipset 9 motherboards, which kinda implies that Intel may chose to screw Chipset 8 out of Broadwell support.

Though that's not a concern for I7 owners, it's more of a concern for lower end I5 and I3 owners who hoped to upgrade to Broadwell.

Or, it could be fake and I'm spreading misinformation :)
 


You seem to be much more up to date than I am so it is perhaps me that is spreading misinformation from the short news stories I read here.

Your take on things seems much more realistic than what I understood, think I'll just kick back and wait to get something solid from Intel before I comment again on CPUs. I follow the graphics world closer as it's is more fluid and interesting.

Thanks for your insight :)
 


That's up to or at best a 9% average performance increase and that depends on which set of benchmarks to look at.

While having more USB 3.0 ports are nice for faster transfer rates to/from a hard drive, it is not exactly absolutely necessary unless you plan on connecting many external drives. I'll give you SATA 6Gb/s, but actual performance is definitely nowhere even close to double the performance of SATA 3Gb/s.

The extra instruction sets are TSX (Transactional Synchronization Extensions) and AVX2 (Advanced Vector Extensions 2), BMI1 (Bit manipulation), and FMA3 (fused multiply–add)

TSX is only available in the non "k" model CPUs (present in the i5-4670, but not included in the i5-4670k). It's purpose is to help speed up multi-thread programs as long as the TSX instructions are used. Therefore, it could be possible that some multi-threaded programs can perform a little better on an i5-4670 vs. a stock speed i5-4670k.

AVX2 is available for all i5 / i7 CPUs to the best of my knowledge however, this instruction set is specifically used to improve financial and scientific modelling performance. Therefore, very few people will actually gain any benefits from this instruction set.

BMI1 is basically used to improve data encryption and file compression performance. Great if you do a lot of data encryption/decryption and file compression / decompression. But for most people this will have a negligible impact on performance improvement.

FMA3 is likely one of the main reason why Haswell has better performance than Ivy Bridge.Simply stated this instruction set "fuses" add and multiplying commands into a single instruction, rather than 2 separate instructions.
 


1230v2 vs the 4771 is $85. 😉 For a non overclocking gaming rig, I wouldn't ever consider buying a locked i7 when the Xeons are just as capable and a good deal cheaper. Only way this would be any different is if I was getting a really good deal on a used one. Buying brand new for a gaming rig, you get more out of your $$$ by going with a Xeon and a better GPU.

 


I was talking about Haswell to Ivy differences of the same class.

I too realize that Xeon costs a lot less, but it's not that available around, for example when I was building my rig I couldn't get any.

 


If you built your rig as soon as haswell came out, or live outside the US, I could see the Xeon Haswells not being out when you built your system. Haswell, to me, isn't worth the added cost over ivy. It doesn't offer me anything I need over what my current ivy system does now. Only way I would buy Haswell, was if Microcenter had a deal that was too good to pass up and I absolutely needed to replace something in one of my rigs.
 
Oh yes, ofc if you already have Ivy rig, then you are golden. I totally dig it, as a matter of fact I'm pretty disappointed with Intel - Haswell is a huge letdown - new architecture and only 5% improvement over "old"? That's a fail, honestly. Yeah, I get that Haswell is not about desktop performance, but it is still disappointing.

And yeah, I'm living in some shitty third world country. I guess if we are not at the point where I am getting shot for writing such things, it's not that bad, but other than that... :)
