I'm considering, mostly just for the fun of it, upgrading the processor in my M93p Tiny desktop. According to CPU World, the socket type is a Socket 1150 / Socket LGA1150 / Socket H3. My M93p currently has a Intel Core i5-4570T (http://www.cpu-world.com/CPUs/Core_i5/Intel-Core%20i5-4570T.html), dual-core 2.9 GHz. I would like to put a quad-core processor in it, but I am concerned with the potential for increased power consumption and thermal load.
I am looking at the following options for upgrading it:
As I said, my major concern is increased power consumption and thermal load. The Thermal Design Power (TDP) of my current processor is 35 watt. The TDP of the processors I am looking at upgrading to range from 35 watts (the lower powered i7-4785T, not my first choice) to 88 watts. If I go with a TDP of 65 watts or 88 watts, is my heat sink going to be able to handle the thermal load? And is the power supply going to be able to handle the added power consumption. Any help would be appreciated. Thanks!

Updated to the latest BIOS.
Swapped in a 45W Xeon 1275L V3.
It worked !! and the performance increased to double in passmark.
I think you will able to use low power comsumption Haswell CPUs.

Hi, I saw your post that you have upgraded your m93p tiny form factor CPU to Xeon E3-1275L v3 with 45W TDP. Does your machine handle it good enough so far ? Did you encounter any issue like heat problem or hang after running for some time ? I wanted to upgrade to this CPU as well.

Was totally confused today. Based on specifications, Tiny M93p works with i7-4785T.
Bought i7-4785T SR1QU few days ago, swapped into M93p and nothing is working.
While powered, no LED's a light, just fan constantly spinning. No video, no boot.
Absolutely identical behavior as described on this thread:
Latest bios (FBKTCGA) installed, this i7-4785T CPU works well on my desktop Z87x mainboard.
Any ideas on wth is wrong with Tiny M93p?

I personally can confirm that, the XEON E3 1275L V3 totally work on my newly upgrade M93p tiny Model 10AA,
I have run the upgrade XEON CPU for a week 27/4 with high load >85% CPU resource all time for media transcoding with FFmpeg lib, apis serveving on http request on linux box. so far so good. the teperature is not hotter then the previous core i5-4750T , the original power adaptor coming with the M93p is good enough to handle all stress test for continous 4 hours with seige-win.
I also test the XEON e3 -1275L v3 on my M83 tiny that run Q85 chipset , a little bit different with Q87 chipset on M93p tiny. the M83 with and BIOS information shows exactly teh XEON E3 1275L V3 as it is.
So just take the aftermarket XEON chip that pulled from rack server that sold on ebay, the do upgrade yourself, remember to buy the heat-glue to paste to the CPU and teh heatsink sink once you open the heatsink, you should not use the thermal paste silicon that manufacture pasted anymore.
This may be the good new for one that want to upgrade the XEON to the little beast tiny CPU from Lenovo.
Discalimer: Do the upgrade on your risk, since i can not garanntee that you follow steps strictly the CPU upgrade procedure.
Tested: the XEON E3 -1275L V3 work on socket 1150 , Q85, Q87 chipset test and stress test with half a day with 65W original power adaptor.
performace seems double the core i7 on passmark result.
I'm using two lenove m93p and m83 tiny as load-balance web server, one of these also doing the task of media transcoding with FFmpeg for 5 TVs simultanously.

Hi, friends. As i've mentioned earlier, i've tried to run my M93P Tiny 10AB with i7-4785T without any success, so i sold it and bought Xeon E3-1275L v3 even cheaper on ebay ($150 vs $190). While searching, found info that to be able to install i7-4785T, your Tiny should be late 2014-2015 models, like 10E9 etc. They were equpped with i5-4590T, not 4570T from factory. So, if you have most common 10AA, 10AB (2013 year), i7-4765T is the fastest option possible for you. Or the boosted +10W (45W) option with Xeon.
Okay, back to my Tiny with Xeon. Works perefectly for about two weeks, never ever had any problems running it at high loads.
Aida64 burn-in CPU+GPU+Cache test never shows throttling or temperatures over 74°C with something like 2400 rpm fan. With OCCT test i was able to see peak 81°C after 2 hours continuos testing in "CPU:Linpack" mode. While getting such temperature values, CPU fan starts blowing at 3300+ rpm and decreases temp back to 78°C with 2400 rpm. So the cooling system is pretty enough to use with 45W CPU plus little reserve for hot days but nothing more. I've seen youtube video with i3-4170 (54W TDP) M93p upgrade and autor noticed he have cooling problems with such power and they're not possible to be fixed by changing the thermal grease or even opening the case.
I think many of you want to see real perfomance difference between their "stock" i5-4570T and Xeon E3-1275L v3. So, i made them. PCMark, Aida64, Passmark, Cinebench, WEI. My system was equipped with Lenovo 90W PSU from factory, thus i don't know what results you will get with your most common 65W PSU. But i personally can confirm that i have seen 47W power drawing on Xeon 1275L v3 from Tiny. That's just the CPU. Plus 8,7W by DDR3 16Gb + 5W SSD. Add some USB devices, chipset, mainboard circuits etc. and decide.
Back to test results.
Xeon E3-1275L v3:
As you can see, there is significant perfomance increasement with anything that uses multiple core.
But, from the other side you will get tangible decreasement in GPU perfomance. Because of Xeon's integrated video is Haswell GT1 with 40 cores, 10 CU's at 1200 MHz while desktop CPU like 4570T have Haswell GT2 with 80 cores, 20 CU's at 1150 MHz. GPU cores rule the same as CPU core quantity.
There's is one more variant of Xeon i found interesting, but almost 99.9% it will not start in our systems - Xeon E3-1268L v3. Compromise variant between CPU/GPU power, it have P4600 graphics with 20 CU's at 1000 MHz with 2.30-3.30 GHz frequency and 45W TDP. Rare CPU, found it on eBay for $175. I was not able to find any info regarding it's BIOS support on any MOBO websites like Asus, Gigabyte, MSI etc. Passmark database have only one result record, made on some kind of industrial Siemens PC. While Xeon E3-1275L v3 is supported almost on any Q87+ 1150 mainboard, no matter desktop or server.
I've decided to stop on E3-1275L v3 variant and not to try i7-4765T since Xeon is top option, without doubts. Such upgrade uses the manufacturer's reserve for power and cooling systems capabilities and does so exact within a reasonable range. I may obtain, let's suggest, 23 fps on i7-4765T instead of 17 fps with current Xeon E3 in some games after applying LQ settings, but anyway integrated video is not the forte of our systems and both variants won't be comfortable to play, so I'll use what he's good at - CPU power.
If anyone have Xeon E3-1268L v3 on their systems, it'll be interesting to try whether it will run on M93p Tiny, please share results.
Also it'll be great if someone is able to decomnpile or provide any kind of utility that can show us real CPU support list that hardcoded in M93p Tiny BIOS. There's none official info about E3-1275L v3 support on Tiny M93p, but it is working. I think it's the only way to figure out on why some systems works with i7-4785T while others don't.
