Pros: This is to the person who said: "This CPU is a beast. Everyone thinks it cannot do anymore than x16 lanes... BUT IT CAN..
This processor paired with the Asus Z87 WS motherboard, is a absolute monster.
The Asus Z87 WS is the only board that can run DUAL X16 TO EACH VIDEO CARD. OR 4 vid cards AT X8 EACH!"
(read other thoughts and cons for my myth busting! and for answers to common questions, which include what is hyperthreading? should i get a i5? what is tdp, ivybridge has a lower tdp? 4820k or 4770k, z87 vs z79? is haswell better then ivybridge and how well does the i7 4770k oc? and more )
Spending money so much on the Asus Z87 WS for 16x/16x is ridiculous, because z87 motherboards are pcie 3.0 which have double the bandwidth of pcie 2.0 (which was used by older Intel platforms and the newest amd platfroms), so 8x/8x on pcie 3.0 is the same speed as 16x/16x on pcie 2.0. EXCEPT that pcie 3.0 is still faster because pcie 2.0 (5GT/s) has a limit of 5ghz on memory and most video cards come around 6ghz these days (pcie 3.0 is 8 GT/s so it uses up to 8ghz). A 16x pcie 2.0 slot has bandwidth 8gbps, a 8x pcie 3.0 slot has 7.875gbps, there are no videocards to this date that can full saturate these slots. Bencmarks show 0~1fps difference when using pcie 2.0 x8 and pcie 2.0 16x using a 7970ghz. I would assume the same for the latter.
All in all folks, dont worry about pcie slots and bandwidth, there is NO difference at all, those 0~1 fps difference you see in benchmarks may as well be just biased or a placebo effect. Go get a decent mobo for $120 to $150 and put that money saved into a better cooler or graphics card or a larger ssd.
OK i will try and be and unbiased as possible, I am not a Intel fanboy ftr (my old pc which i forever love for lasting me so darn long with kick bum (no inappropriate words allowed lol) performance at a cheap price, has a athlon ii x 3 3.1ghz unlocked to a phenom ii x4 3.8ghz with hyper 212 + on $50 mobo with 4850 oced from 625/993mhz (core/mem) to 850/1250mhz (i get 50fps on dmc dx10 on max settings 1080p) all for $500 which i bought 2008 lol) it just stands amd is so behind in desktop high-end cpu tech the i5/i7 wins in value and performance IMO, even though I had preferred amd over Intel because usually that's where the bang for the buck used to be. I also liked nvidia over amd but with the 7970 dropping to $300 (and the r9 280, a 7970 rebrand coming out for the same price) amd is a no brainer. Don't forget about the mantel API, which looks really exciting.
Haswell cpus are so power friendly that things like power-phases, and those fancy shenanigans wont affect over your overclocking, maybe it would if you were using something that needs a lot of power from your mobo (like a phenom 2, or FX 8 core cpu, but those takes like twice the power a i7 would).
Motherboards will be the component that has the least effect on your pc performance, BUT it is still literally the center of your pc, so it is important to pick a reliable motherboard, so spend the money to get a good and reliable one within you budget AND DO NOT SPEND MORE THEN YOU NEED TO you will get nothing out of it. Put that towards a good ssd/gpu/cooler/your next meal, etc.
Other Thoughts: (cont'd)
Another myth that needs busting is tdp, these cpus have a 10w higher 10tdp then last gen. THAT DOES NOT MEAN IT USES 10w MORE THEN THE LAST GEN. In fact haswell is more power efficient then ivybridge if u check the reviews.
Heres the definition of TDP: "The thermal design power (TDP), sometimes called thermal design point, refers to the maximum amount of power the cooling system in a computer is required to dissipate. The TDP is typically not the most power the chip could ever draw, such as by a power virus, but rather the maximum power that it would draw when running "real applications". This ensures the computer will be able to handle essentially all applications without exceeding its thermal envelope, or requiring a cooling system for the maximum theoretical power"
What this means is the more tdp, the more heat/power headroom it has, which translates to better overclocking. WHICH IS A GOOD THING.
Another thing I noticed about this cpu is that it generally hits a wall at 4.5ghz (atleast the average silicon) which scored it a 9.8 in cinebench r11.5, the 4820k (ivybridge-e) hits a wall around 4.8ghz (thanks to many improvements to its internal heatsink and larger tdp, and much lower temperatures) but score a 9.4 in cinebench r11.5, even though it is using quad channel (dual channel is fine, memory clock above 1600mhz MEANS NOTHING unless you are overclocking stuff u shouldnt touch). So the z87 platform has much more value.
Hyper-threading, what is it and should you be getting a i7 over a i5? My answer: go for the i5, save $100 bucks, get a nice ssd/gpu/cooler. UNLESS You LOTS of video editing, media conversions, archiving, and all that other good stuff. Or if your just looking for a excuse to get a i7 (my case lol) and want to future proof for then next 6 years (good luck??? well, the struggle is real people).
OK now to explain hyper-threading.
Hyper-threading is not doubling your cores. You are adding 4 "logical cores" or rather each of your 4 cores get 2 threads each. You will get UP TO 30% more performance in multi-threaded applications THAT actually use more then 4cores/threads. Remember, A logical core is not a physical core. Having hyper-threading can turned on can actually hurt performance because of "resource contention" (basically a processing collision) but newer cpus have great schedulers so the impact is almost nonexistent. With hyper-threading on, each core will show the OS itself as 2 cores, and lets it analyze its work load and handle it more efficiently (in a nutshell) and is kept more busy (doing more work). with ht turned off the system will try to make best use of the 4 cores and spread the work out efficiently.
I hope this helped you decide what you want, and hopefully it wasn't too much to read. Don't mind the typos! It was a lot to type. Source: I like to researcher and learn this stuff on my spare time and i had also worked as a computer service technician and salesperson at a electronics and com
Pros: Has a excellent auto overclock feature, has all the features you need and much more reliable then most other motherboard manufacturers. Something that will have some ppl confused is the onboard audio, most boards have the alc 892, this one has the 889, the 889 happens to be better then the 892, the 892 has 95 db s/n ratio where the 889 has a 108 db s/n ratio.
It supports sli!
Other Thoughts: Tthe raw S/N ratio of the DACs in the codec chip, and says nothing about how well the motherboard maker integrated the codec into their design. Unless they've taken great pains to shield the audio section from EMI and provide extra filtering (dedicated voltage regulator) for the power to the codec, it seem to me theyve done a better job then most manufacturers, especially at this price range.READ FULL REVIEW
This review is from: MSI 870-G45 AM3 AMD 770 ATX AMD Motherboard
Pros: Great board for gaming on the budget, does everything you need without any many flaws or major flaws, and looks good.
It unlocked my athlon II x3 3.1ghz in to a phenom II x4 B45 and oced to 3.8ghz 1.312v stable prime 95 x64 all tests 24hours.
Cons: Make sure you are not using a bottom mounted psu cause the the cpu 4pin will not be long enough, i had to solder a piece of an old psu to my new one to make it long enough.
The bios is complex, so if you need to change ram setting or OC it and dont know what your doing, go get a different mobo, the bios is hard to use.
Other Thoughts: Make sure you know this board is a 770NB board not a 870NB
-Bios flashing is scary xD
