    Still another gen I think before I upgrade...

    Nice review Hilbert.

    I'll just wait a few days to see the comments of Skylake owners and then I'll go and buy. My stuff is getting old and I like to upgrade every three years or so. Especially my PSU definitely needs to be upgraded (bought late 2010).

    Next gen is Kaby Lake, its neither a new Arch or a die shrink, so really not sure what anyone thinks next gen is going to bring.

    Skylake platform has already had some upgrades, DMI 3.0, lots of PCIe 3.0 connectivity for the PCH, USB 3.1, DDR4.

    Not sure what Kaby Lake is going to bring, perhaps a slight bump in clock frequencies on the chips, maybe some more USB 3.1 ports

    And this is about a year away! The next "big thing" will be Canonlake, about 18-24 months away.

    So anyone not upgrading now is likely to be waiting another 2 years for a potential upgrade. Which will no doubt disappoint everyone again with their unrealistic expectations of massive IPC gains, and huge increases in FPS since Canonlake is just a die shrink of Skylake with architectural tweaks.

    I feel the same matey

    IMO DDR4 is a completely pointless change - it was only done to force people to throw away hundreds worth of perfectly fine DDR3 modules and have to go out and buy replacement DDR4 modules. Absolutely no performance improvements at all with the stuff.

    Can I ask do all you people leave your CPUs with these overclocked voltages all the time or do you just do it for the hour you are doing 3DMark benchmarking?

    Reason I ask is I really can't see the reason or advantage of it at all. I mean have you seen the amount of extra power it uses for no reason or benefit at all. I mean most of you that seem to do all this overclocking seem to just use your PCs for games and for that use this overclocking is completely pointless.
    Seriously I'm getting a bit sick listening to morons and talking about their overclocked CPUs which are idle 90% of the time and at the same time increase the power from socket by a massive amount for 100% of the time FFS! It's ridiculous. There is a reason Intel sets the speed on the individual CPU when it leaves factory - they did extensive tests on each die and find the optimum voltage and cpu speed for each one to minimise the power usage while idle.

    Wow hold your tits mate... Some of us are running with speedstep etc on.
    I for one am running @ 4.3Ghz 1.24V and idle 0.8V still (also at 4.3Ghz)

    Some boards and CPU's arent happy with a high OC and powersaving options on. It all depends on the user and how much they know and read on forums what can be achieved. Most of the times you see that they recommend to turn everything off and most do so without testing themselves.

    IMHO a good OC'er goes for maximum OC and stabilty with powersaving options ON.

    Ps: i also like low idle temps, idle my rig is totally silent. Controlled with Speedfan with temp fan control. Loving it.

    CPU: 3930K is cooled with a Nocuta D14. Room temp: 23c, core temps range ~26,28,27,25,28,29. 2x GT@500RPM.

    GPU: MSI Gaming OC 980 TI Temp: 30c, fans @25%
    Motherboard: Temps Chipset are ~35C

    All cooled with my Silverstone Fortress FT-05. Both AP are @650RPM.

    Great review! But seems CPUs are no longer a reason to upgrade when it comes to gaming. The pentium g3258 is not far off from the 6700k as well as the 5960k :D. Although I think other games would have shown a wider spread in the benches.

    Pretty much. The performance improvements were meant to be as a result of higher speeds, however that has shown not to be the case in the review. However, I still would like to see a review of standard DDR4-2133, and the 14-14-14-35 DDR4-2400 both at standard CPU clocks, overclocked clocks, and tweaked timing settings (including slightly upped RAM voltage) as I do believe that the right faster RAM modules will show a difference. It might sound counter-intuitive, but a good tweaked DDR4-2400 could perform better than DDR3-3200 currently.

    This is what makes me laugh. People say I can't justify cost etc. of replacing cpu/motherboard/ram etc. because as we all know it costs hundreds to do this... and yet....

    ...people don't realise or care that they are actually paying hundreds a month/year more on ELECTRICITY BILLS because they are doing all this ridiculous stress tests and overclocking and Folding@Home type stuff that is massively increasing electricity usage.

    These new generations of cpus are not designed to be more powerful - they are designed to be more POWER EFFICIENT. That's what you get when you upgrade - not massive performance increases.

    Intel knows they have to redesign their tech to suit mobile, tablet and massive server / hosting environments and for these power efficiency is number one, not a performance increase - they know that even a first gen i7 has enough performance for most people and what they do.

    Lets see.

    [​IMG]

    A 1 watt increase compared to the 3770K at idle.

    [​IMG]

    A 3 watt increase compared to the 3770K at load.

    Breaks even performance/efficiency?

    Its not but some places like Novigrad is heavy on the CPU.

    Right but do you care about power usage or elecricity bills at all?
    Can you do a test and power a WATT meter on your power plug going into your PC and measure the idle power usage and then the gaming power usage with your overclocked setup and then do these two again with STOCK settings on CPU/GPUs. Then see what the difference in power usage is. Now convert that to whatever way the electricity company charges you per unit and figure out how much extra a month/year it is to leave things overclocked. You will be surprised how much more it is. Is it worth it? It's up to you, you might get a few more FPS but really who gives a f about a few more fps - if you really want that get a better GPU - don't overclock, but it will probably be the price of a new Intel CPU per year...

    Really not sure what you're getting at. You suggest for people to upgrade every year instead of overclocking their current system to save a few pound a year?
    Do you work in marketing?

    No it won't for 99% of applications. There is a reason that CPUs have a large very fast level 1 RAM cache and multiple levels of slower RAM cache (level 2, 3) which is still way faster than any DDR3 or DDR4 memory. It's because normal compiled software will NOT be reading large chunks of memory as it works - it will be working away with 100% of its code and data in the CPU cache - it might have to update its cache with reads from main RAM maybe 2% of the time.
    The main RAM of a PC is meant to be just a large scale slow archive of data which the CPU occcasionally accesses to fill its high speed processing cache buffers. Main RAM does not have to be very fast.
    Problem is most gamers don't really seem to know how computers, cpus, software actually works at all so marketing men and sales men take advantage with numbers to sell more pointless **** and upgrades...

    Right not much there but can you imagine the difference in power between a first gen i7 920 and one of these in idle/load? An especially an overclocked i7 920 and one of these overclocked... A lot...

    Fun fact, my Mobo sets the vcore (on stock, with turbo) to around 1.28 so with my OC im achieving a higher clock with less vcore. So gaming im using less power with a higher OC. I really dont want to run my rig at the bleeding edge all day when idle, and i only have a 500Mhz oc above stock.

    No I suggest people give up this stupid overclocking altogether and leave their systems at stock voltages. There is no logical reason for people to be doing this overclocking.

    If you need more CPU computing power (for whatever reason) then get a more powerful CPU or dual socket server board - Intel will happily sell you an 18-core Xeon if you need that level of parallel computing (and its still at only 2.3GHz).

    This overclocking is only for muppets. Literally the big boys in industry laugh at this **** - they push cpus and motherboards to suckers by using the overclocking marketing.

    Really this is the computing equivalent of the boy racers in their Honda Civic de-catting, putting on a larger exhaust, changing intake filter and then thinking their car now increased by 100bhp and now competes with a Nissan GTR.

    Do I work in marketing? No. I have 20 years in industry and degree in computer science where i specialised in advanced computer architecture, hardware and parallel computing.

    In your opinion anyone with an Intel K processor is a muppet? Your de-catting analogy is flawed. Installing a Turbo is more appropriate.
