Why is this new system slower than this older system?

Hi Guys,

I put together my own system a couple of years ago, and have been really happy with it (also built another exactly the same). We recently needed another, so for the sake of ease i bought a pre-built one from SCAN (with some tweaks).

I was under the impression this new pc would be faster that the one i built two years ago, however ever since first use its always seemed generally slower in comparison to my own. We are graphic designers, and it is just general use like saving, opening, loading thumbnails, computing things in adobe illustrator and photoshop etc which seem to be slow in comparison.
I'd be happy if it was just anywhere near my other pc, however it is irritatingly noticeable.

Slower (but newer pc):

The components that weren't as good, were the data hard drive, the graphics card and the ssd.
I have since replaced the basic data hard drive with a fast WD Velociraptor which is what im using in my built pc. I've also put in the same graphics card (pulled out of the second own-built pc) and finally put in a new Samsung 850 pro ssd to replace the samsung 850 evo which was in - which should be marginally faster than my custom built's slightly older samsung 850 pro.
Non of these really sorted the issue, which leads me to suggest the CPU isnt performing as fast?

Anyway, you get the picture! If anyone could have a look over the system specs in the links and see if they can find any potential differences, that would be fantastic!

Let me know if any more info is needed!

Thanks in advance!!

It's long shot, but if we ignore possible faulty hardware there is one option that it's just wrong power options for CPU.
In that CPU-Z for new CPU I noticed it was on 800MHz, does it stay at such low frequency or it jumps to it's max 3.5-3.9GHz? If it stay at lower speed try to check power option in control panel maybe you got some balance or saving plan active even if its on desktop. Also you can directly control min-max CPU state in advanced plan settings (Processor power management). This would explain why boot is fast as those power management rules kicks in after OS boot
You can also check bios some computers (mainly laptops, but maybe also some desktops) got power settings for CPU there too.

I had such problem once, well it was...

@Cons29 : it is just general use like saving, opening, loading thumbnails, computing things in adobe illustrator and photoshop etc which seem to be slow in comparison. Haven't tried gaming on the slower pc as it is only used for graphic designing. Boot time is incredibly fast - can't complain about that.

@getochkn - Well the raptor drive is exactly the same one im using in my own built pc, so i don't think that is the issue..?

I had such problem once, well it was on laptop but it was underperforming and later I found that some software from that laptop vendor was crashing and setting power management on 25% or so meaning constant ceiling of 800MHz for CPU.

Small warning, in case you would be changing that power state and you choose to use 100% min power state be adviced that in that case your CPU will constantly run on 100% frequency on all cores but also it will limit Intel Turbo boost meaning that now one of your cores can auto overclock up to 3.9 GHz, in case you set it on 100% min state, all cores will get to max speed which will be lower (probably 3.7GHz) as turbo boost can overlock only one core to 3.9 and in case it overclock more cores each of them get overclocked for less.

I think i've finally found the issue!

In the power plan setup by SCAN, they'd set the minimum processor state to 5%. This was causing the system to run so sluggish! It's FAR better now set it to 100%. Why they've set this so low is beyond me - what's the point in spending alot of money on a system for it to just run at a minimum speed!
I could understand if this was set so low to save power on a laptop, but for a desktop i've no idea why!

Perhaps for playing games it would increase the processor speed as required, however it obviously wasn't increasing enough for general windows use and photshop use for it to be as snappy as possible.

Thanks alot for your feedback anyway guys! Appreciate it! :)

@pm4 Hah, you replied as I replied myself! Yes that is the issue i'm almost certain. I noticed the 800MHz also, which prompted me to check it out, and found elsewhere on the web people had this issue. I have set the minimum to 100% for trial purposes for the meantime.

Regarding your last paragraph, would you suggest running it at less than 100%?

If you set max state at 100% and min state at for example 0%, your system should automatically adjust speed to it's needs. If it's not happening it's weird and may be cause of problems. I think default options are 5% min and 100% max.
So if you got 100% max it should always automatically depending on system load get up to max speed (3.5 - 3.9 GHz) if that is not happening there is something wrong, but no idea what that can be.
So try to check MAX settings if they are not 100% put them on it. If it wont help and you really need to use 100% min state it should be fine.

If you use 100% min state it will mean it constantly run at max speed even when not needed. It should not cause any problems to your system as CPU should be able to run constantly at max power even for years. Only problem is that CPU will ofc consume that power even on idle and also generate some heat.
Other problem as I mentioned is that Intel Turbo boost, wont overclock to max 3.9GHz but to something less like 3.6-3.7GHz.
