Better CPU required?

[kidloco]

Hi,

Recently built a small form factor system made up of the following

• ASRock Z97E-ITX/AC, Intel Z97, S 1150, DDR3, SATA III 6Gb/s, SATA RAID, PCIe 3.0 (x16), DP/DVI/HDMI, Mini ITX
• Intel Core i5 4590T, 1150, Haswell Refresh, Quad Core, 2.0GHz Base, 3.0GHz Turbo, 1150MHz GPU, 35W, CPU
• 16 gb DDR3
• Transcend 2242 256 GB SATA3 Solid State Drive (to go in the m.2 slot of motherboard)
• 250GB SAMSUNG 840 SSD as photoshop drive
• 1tb WD blue drive for everything else

Whole system runs great for 95% of the time, the only issue im having is when using Photoshop or Lightroom. It seems so much slower then my old full sized system which had a i5 3570K with a Nvidia 660 GPU. I knew the small form factor would be a compromise but was hoping for a little more when pushed.

Ive been looking at swapping hte CPU for either

i5 5675C

or

i7 4790T

Would either be worth it, ie will they give me the boost im after?. Ive looked on all the GPU comparisons and it seems gains are to be had, but real use feedback would be great.

the 4790t is more power efficient, and benefits from hyperthreading, although the i5 has a high base clock, you're likely to see more benefit from the i7. Although you cant really go wrong with either.

Here's a nice 4-way comparison

It's no wonder the 4590T feels slower than your old 3570K - it's 2 GHz base clock compared to 3.4 GHz. This is why I always urge people to avoid the low-power models. If you buy a regular model and find it's too hot you can undervolt/clock it yourself and achieve just as good an outcome, while keeping the option of a higher clock speed if cooling allows.

Saying that the 4790T has more generous clock speeds (2.7 GHz/3.9 GHz) though that's still anaemic when not boosted.

Between the two you've mentioned I'd probably get the Broadwell (not considering the price difference) because the base clock is higher and hyperthreading tends not to be that useful in desktop graphics.

What HSF have you got and how's that case for dumping heat? If it's decent despite being small I'd probably go for a regular model (i5-4690K for example) and adjust the speeds and voltages yourself.

You would have benefited lots on your old system having the 660 GPU with CUDA support.

That'll be why your SFF seems slow in comparison.

As above, those software uses hardware acceleration which relies on a decent GPU. The Intel IGP is what's holding it back. Maybe find a CPU with Iris graphics, they perform considerably better thanks to the eDRAM cache. I think for Haswell they have an R at the end of the name.

Hard to tell if it's the CPU or graphics as the OP didn't describe the slowness.

Maybe find a CPU with Iris graphics, they perform considerably better thanks to the eDRAM cache. I think for Haswell they have an R at the end of the name.

Thought they were really expensive?

The i5-5675C seems to have Iris Pro 6200 according to the ark comparison. The others have HD Graphics 4600 which is indeed slow.

Should have built a proper small form factor with a 4690K/6600K inside.

Do you have photoshop on the ssd ?

Sorry for the lack of response , been away with work.

Yes photos hop and lightroom are on a sad in fact they have a whole ssd just for them, I've maxed the cache file they use and that has helped a bit but it still just feels slow when moving between images on light room, and when exporting batches of images.

The iris pro 6200 of the i5-5675C is the reason it's on my shortlist I knew losing the graphics card would have some impact, but not all that much as I had actually turned off the gpu support on light room as it never played nicely for me.

Heat sink is the Ince that came with my old i5 which is actually really good, cools well and is pretty near silent with this rig. Case also seems great at getting rid of what little heat there is due to the mesh top and I don't have the case stood tall on its side, so heat can disperse quicker.

Seems there is no straightforward choice between the 2 chips mentioned I was hoping you would all say get a specifix one.

well when the graphics card is gonne ur gonna need a more powerfull cpu now..
