Planning to get a Intel i7 7700T for my low power Desktop, Will this be enough as for 7th gen?

A24G_1_201702121051283876.jpg


I going put this CPU on a
H270 Motherboard with a 64GB DD4 Memory.

Mostly not use for gaming, and but i need this.\

Is it good?

Oh, and for a little comparison about performance....

PC = Core 2 Quad 9550, 8GB 1066MHz DDR2 RAM, SATA2 bus, 1x 250GB SSD, 2x 320GB 7200RPM HDD's in RAID 0, 2x 1TB 7200RPM HDD's in RAID 0
LT (LapTop) = Core i7 4710HQ, 24GB 1600MHz DDR3 RAM, SATA3 bus, 1x 250GB SSD, 1x 1TB 5400 RPM HDD

PC's SSD (remember, SATA2 limited):
Sequential Read (Q= 64,T= 4) : 283.243 MB/s
Sequential Write (Q= 64,T= 4) : 268.415 MB/s
Random Read 4KiB (Q= 64,T= 4) : 203.193 MB/s [49607.7 IOPS]
Random Write 4KiB (Q= 64,T= 4) : 189.629 MB/s [46296.1 IOPS]
Sequential Read (T= 1) : 273.324 MB/s
Sequential Write (T= 1) : 258.424 MB/s
Random Read 4KiB (Q= 1,T= 1) : 23.890 MB/s [5832.5 IOPS]
Random Write 4KiB (Q=...

35 watt cpu with 64 gigabytes of ram sounds like zfs server.

64 gigabytes of ram does is alot for a low power desktop.

I'm sitting at about 6.5 gigabytes of ram in use with steam, winamp, bit torrent, crashplan and firefox open on Windows 7.

As the previous post may have missed the Intel Core i3-7300T Processor, Intel Core i5-7600T Processor and Intel Core i7-7700T Processor all use 35 watts according to intel.

So an i7 can still have the same tdp as an i3.

What is your intended use for this computer.

An i3 / i5 with 16 gigabytes of ram is enough for the majority of people, although if you run multithreaded apps or run alot of single threaded apps the i7 can be beneficial.

Same with Ram, 16 gigabytes is enough for most but if you open alot of programs or use phototshop, Adobe cs6 or similiar graphical editing program, you don't need more than 16 gigabytes.

As for the original question

Is an i7-7700T good?

Well its a normal i7 with 4 cores and 8 threads with a tdp of 35 watts.

Each thread runs at 2.9 gigahertz and can turbo up to 3.8 gigahertz.

(When I say normal I only mean 4 cores 8 threads with intel not trying to trick you with the laptop version of i7 which could be 2 cores or the i7 extreme editions that can have more than 4 cores / 8 threads.)

For comparison:

i7-7700K it's big brother

Also a normal i7 with 4 cores and 8 threads but with a tpd of 91 watts.

Each thread runs at 4.2 gigahertz and can turbo up to 4.5 gigahertz.


So if you were running single threaded applications you would almost ironically choose the 7700T due to since it would only use a single core that core would be boosted up to 3.8 gigahertz most of the time, although you could argue just drop down to an i5 if that was the case to save money.

In other words if you ran a multithreaded application that used all of the cores on the 7700T you would most likely only have like a 3 gigahert processor since the cpu would be unable to boost up to 3.8 gigahertz with so many threads active.

If you were running highly demanding workloads with blender or handbrake then the i7-7700k would be the way to go.
Even if you used all the cores you are still guaranteed 4.2 gigahertz.

SSDs are more secure than hard drives due to no moving parts.

As long as you don't write multiple terabytes a day to them on a database server they should last many years before wearing out normally.

Anandtech did a special a few years ago on the Samsung 840 1 terabyte evo.

http://www.anandtech.com/show/7173/samsung-ssd-840-evo-review-120gb-250gb-500gb-750gb-1tb-models-tested/3


I should be able to write 50 gigabytes a day to it for the next 60 years before it fails.

1.09 petabytes if my math has not failed me.

50 gigabytes x 60 years x 365 days in a year = 1,095,000 gigabytes


Edit: Math was right, reading comprehension was wrong. 50 gigabytes a day instead of 100 gigabytes. Still a big number.

Yea i don`t believe it, I going stick with HDD (Keeping at a decent slow Hdd speed).

So far will be getting
Intel i7 7700T
Some kind Coooler
x4 1TB Surveillance HDD
64GB DD4 Memory
Seasonic Flagship PRIME TITANIUM 650 Watts PSU

Is that good?

Those 4 terabyte drives;

Are they going to be in a JBOD, raid5 or raid10?

I would switch to the Seagate raid drives if you are putting them in a raid 5.

Surveillance oriented drives are ok to use in a JBOD or raid 10.

I guess another question would be how many cameras?

10 - 1080p cameras will most likely out strip the write speed of 4 hard drives especially if the cameras are connected by ethernet sending uncompressed frames at 30 fps.

The write speed of a raid 5 with 4 drives is the equivalent to the write speed of a single drive.

The write speed of a raid 10 is equivalent to the write speed of 2 of its drives.

The write and read speed for a raid 0 is equivalent to 4 drives, but I doubt you would use that one with a need for data security.

A handy calculator for Ethernet Cameras:

A handy raid performance calculator i use:
http://wintelguy.com/raidperf.pl

Be sure to set the raid calculator to 100% writes.

My opinion, you might still consider a small SSD for the operating system, it will greatly improve system responsiveness.

Also, an i7 7700T is not any more efficient than a normal 7700 when running at the same clocks, the 7700 can just go to higher clockspeeds and finish the work sooner, before going back to a low power state. The 7700T is only good for running in cooling-constrained environments.

650 watt power supply is massive overkill for a system that would probably run comfortably on a quality 250w unit. Having a larger unit wastes power because power supplies are most efficient when they're more highly loaded.

EDIT: The most secure RAID you might consider is either RAID 0 or 5. 0 mirrors data so you lose half of your space, whereas 5 would cause you to lose only 25% of your space (as I understand it).

If your stomach can hold 1 gallon of food, and you eat 1 gallon in 15 minutes one day, and you eat 1 gallon in 45 minutes on another day, on which day did you eat more food?

This about HDD and SSD.

SSD will have its performance durability worn out faster. I do not know why heck you mixing it up with food. Irreverent comparison.

Just waiting for a user with a proper response, so i can pick a final answers..Waiting for user answer my topic thanks.
