i3 6100 and memory

[biggiepk]

Hi guys.

I wanna know if there is big difference betwenn DDR3 and DDR4. Here are two options that i can buy:

Don't ask about prices i live in fcked up place, and yea there is no black friday for us, and no avaliabe shiping also so..

 

CPU : i3 6100 - 180$

MOBO : ASUS H110M-K D3 - 94$

MEMORY : DDR3 Kingston FURY 1866Mhz 8GB - 79$

 

 

CPU: i3 6100 - 180$

MOBO: Srock B150M HDV - 119$

MEMORY: 8GB DDR4 2133Mhz Kingston fury 108$

 

So my question is should i pick DDR4 and be full on new platform? Also is there difference betwen 2133 and 2666mhz? Should i pick 2666? Also i heard DDR3 with skylake can make problems if the memory is more than 1.25V?

 

Thanks guys

Unless you run onboard graphics it will make no difference at all.

Why don't you get a haswell I5 for the same amount of money (or is this what you mean by the prices are fvcked up)???

[Godlygamer23]

Running at a higher frequency helps with bandwidth throughput. Will it do anything in your situation? Probably not, unless you're doing things that might benefit from it like video editing, photo editing, or using the IGP. The difference between DDR3 and DDR4 is negligible for most users.

I was thinking the same thing.

Nahh, i wanna skylake

your loss

A 4460 will outperform a 6100 by around 60% your choice is quite poor.

[biggiepk]

Oh really that much? Wow

Not exactly true. People have proven that rumor to be false time and time again. I myself put it to the test on my current Pentium G4400, and proved that the difference between 2133mhz memory and kits up to 3200mhz make on average, a 10% difference in minimum frame rates.

This video was the basis for my test.

 

 

 

There are even threads from over a year ago, discussing this subject. http://www.overclock.net/t/1487162/an-independent-study-does-the-speed-of-ram-directly-affect-fps-during-high-cpu-overhead-scenarios

 

DDR4 is the future. Clinging to DDR3 just is not wise at this point, especially considering how easy DDR4 overclocks. Using a cheap $45 2133mhz CL13 PANRAM kit (Sk Hynix IC's) I got my kit to 3200mhz CL15-15-15-30-CR1 with 1.37vDIMM and have everything super tight.

 

DDR4 is also getting closer to DDR3 in terms of latency. Take a look at my kit in Aida64 below.

 

Not exactly on par with the DDR3 overclocked average of 40ns, but compared to DDR4's stock 60ns, i would say i've bridged that gap quite nicely, and even destroyed every DDR3 kit in memory bandwidth. Bandwidth is important for compression and scenarios such as Primocache, where bandwidth matters more than latency. 

 

TL:DR? DDR4 is cheap, fast, and better in DDR3 for the most part. No need to cling to it when prices are close enough anyways.

Please, stop spreading misinformation. At the very least, back up your extremely bold claims. There is no source ANYWHERE on the internet that will show the 4460 beating the 6100 by 60% in ANYTHING. Whether it be raw compression, multi threaded workloads, single threaded workloads, anything. In gaming, the 6100 will actually cream the 4460, because of the faster IPC Skylake brings to the table, and memory bandwidth improving the minimum framerates.

 

Do not give advice if you have no idea what you are talking about.

Bro it's simple.

Skylake is about 5% better then haswell.

Hyperthreading improves performance by about 20%.

Now let's do some math

2 cores×1.05 because it's skylake× 1.20 because hyperthreading=2.52

4/2.52=1.59 rounded to 60% for convince.

[DKL]

I beg to differ. http://cpu.userbenchmark.com/Compare/Intel-Core-i5-4460-vs-Intel-Core-i3-6100/2310vs3511

 

The Skylake i3 is equal or slightly better than the i5 4460. It is worse in workloads using more than 2 cores, yes, but not by 60% lol...

Where in the world are you getting your facts? Show me where that 20% number comes from. Also, how in the world can you possibly quantify how much performance a given core will give? It is all circumstantial at best, and it never scales that linearly. You are also completely neglecting clock speeds, which the 6100 has a 500mhz advantage over the 4460. You are just plain incorrect in every sense of the word.

The 6100 crushes the 4460 at winrar. Compression that generally loves more cores (as evidenced by the fact that the FX is smashing the rest). Face it. The 6100 is by far a much better buy than the 4460. If OP wanted an i5, he better get an unlocked one and overclock it, because the raw 500mhz advantage and 5% IPC on that i3, coupled with DDR4's bandwidth will absolutely shred the 4460.

No, it actually won't, even with DDR4 memory running at an effective 3GHz. http://www.techspot.com/review/1087-best-value-desktop-cpu/page4.html

@QueenDemetria.

Looks to be ahead on more often than not. Even if its not by much. However, i would like to see more test results. AC:U would have been great to see just how far behind the i3 is in a game that leverages core counts, and i would have like to have seen more serious single threaded games in the benchmark, to get a sense of how much difference that 500mhz + IPC difference would make in gaming.

 

I admit, i over-exaggerated by using the word "cream" but him throwing out a number like 60% was far more exaggerated. 

 

Really, the choice should be simple. Newer platform will most likely last longer. It still has an upgrade path coming to it with Kaby Lake, and the difference in prices are not enough to justify sticking with an older platform. A Z170 board, 8gb of ram, and this i3 will cost about $250-$260. A z97 board with 8gb of ram and the i5 4460 will cost about $280-$290. The reason i use Z97 and not H boards, is because H boards cannot overclock memory, and again, we have seen memory speed having an impact on gaming performance. Paying $20-$30 more for an i5 that will only match that i3's performance just seems silly. I mean, if you want an i5, get a stronger locked i5, or buy an unlocked i5 and overclock. At least then you will have a CPU that without a doubt will perform faster in every scenario.

[Sam Z Man]

Intel themselves say that hyperthreading in most situations increases performance by 20% in most senerios, and can peak to 30% in optimised workloads.

Again, that is circumstantial. Not every application has the same level of parallelization. Amdahl's law still applies. Either way, still a far cry from that 60% performance difference. Intel clearly held no punches with these Skylake i3's. They are priced perfectly, and perform amazingly for their price. At this point, i really see no point in buying a locked i5 unless its one of the higher end models (4690) or if you absolutely can't afford anything else, and cannot trust HT.

bullshit. this has been disproven by Digital Foundries.

stop spreading misinformation on purpose.

i3-6100 works better with high-speed RAM for gaming, and yes DDR3 will fry your Skylake CPU! But only get 2666MHz RAM if your board can use it that is kinda important to check!  (yep that board can only use DDR4-2133MHz...)

Intel supports both DDR3L and DDR4 on Skylake platforms.

[Prysin]

Intel supports both DDR3L depending on motherboard* and DDR4 on Skylake platforms.

No, DDR3 will not "fry a CPU". If you go nuts with VCCIO/SA voltages, then sure. However, people are running 1.8V on DDR4 with 6700k's all over HWbot, and their chips have not fried yet. http://forum.hwbot.org/showthread.php?t=148427

 

Intel's warning is the same as it is every year. Do we not remember when people were frying their Sandy Bridge CPU's with those 1.65v kits? It's not exactly the vDIMM voltages that kill things, but the VCCIO/SA voltages that people add with them to help stabilize the memory. That being said, i would still use a DDR3L kit, just to be safe. We have no information on what kind of degradation will be caused by using higher voltage memory, so playing it safe by staying under 1.4V on your vDIMM is the best bet. DDR3L operates at 1.35V, so it will be fine.

That sounds about right!

Yes DDR3L and note the L!

That's the case for all motherboards though, DDR4 Motherboard doesn't support DDR2, for example.
