Hi

i would like to buy a mini-itx in order to use it with my tv fullHD 46" with all the emualtors, CEMU included. Do you think that this could be ok in order to play CEMU with its best performance adn effects at maximum level? is it better i7 8700 or Ryzen 2700X?

CASE
Silverstone SST-RVZ03
CPU
i7 8700 or Ryzen 2700X ?
MOTHERBOARD
ASROCK H370M-ITX/AC or AsRock B360M-ITX/AC ?
RAM
Corsair Vengeance LPX 2x4GB 2666Mhz
GPU
ZOTAC GeForce GTX 1070 8GB Mini
PSU
550W Enermax Revolution SFX 80+ Gold
HDD
Hard Disk 2,5 2TB Western Digital Blue 128MB
SDD
SSD 250GB Samsung 860 Evo Sata III

Do you think that with this pc i will be able to play CEMU with top performance also with a 4K tv if i will set the output of the emualtor to 1080p instead of 4k? I think that if i want to play it at 4K with maximum effect i need a more powerful pc...

thanks

Windows 7 (x64) or above
OpenGL 4.1 minimum (4.6 is used if available)
RAM: 4 GB minimum, 8 GB or more recommended
Microsoft Visual C++ 2017 X64 Redistributable: vc_redist.x64.exe
These are the minimum reqs.

Since you just said two LGA 1151 motherboards I assume you're going with intel. 2700x in my opinion has more applications, but single core performance goes to the intel. If you're looking to play at 4k, presumably at 30fps like the switch or wii u I think a 1070 will get you where you're going. Just not very familiar with the performance of the mini. Look up benchmarks of the card you're looking at, look at youtube for people playing Cemu with the components you want to go with. Can't go wrong there.
8gb should be plenty for the emulator

yes, i thinnk that an i7 8700 could be better than a Ryzen 2700X, am I right? I'm speaking about emulation in particular...or not?

thanks

Well yes, for emulation maybe. But 2700x has much better multicore performance if you have any kind of workflow or multitask a lot. Problem is I've never seen an 8700, only the 8700k. I know an 8700k will get you 4k at least 30fps no problem, but I couldn't tell you confidently of the 8700 even though they should technically be within a stones throw in performance

well, i don't have currently a 4K tv so i think that this pc could use CEMU emulation at its best performance, isn't it?
If i will use in the future a 4K new tv, i don't know if this pc can run CEMU in 4K at ist best performance..

I think it will. You can test 4k internal textures on any monitor/tv you have by selecting the 4k graphics packs. Should give you a good idea of how well it will perform if you get a 4k tv

ah ok i can test it even if i don't have yet a 4k tv simply choosing the 4K options in the emulators, good!

You get benefits on a 1080p (or other lower than 4K) monitor if you use 4K on Cemu. That is because it effectively does supersampling antialiasing which is the best quality antialiasing method that exists.

What supersampling antialiasing does is to first render normally at very high resolution and then scale down to the monitor. That is effectively identical to Cemu rendering at 4K textures.

For proof and explanation see the guide and its "PS." from my signature: http://forum.cemu.info/showthread.php/79.

ah ok, many thanks!

hi

i have another question: if i buy a notebook instead of a pc desktop, with same specifics i have written above, do you think that a cpu like i7 8750H or i7 8850H, are enough for CEMU with maximum performance (even if these 2 cpus aren't good like the i7 8700 of a desktop pc)?
thank you

Heck I have a Ryzen 2700x before I had a 1700 and I never had any issue to reach a stable 30fps in 4k in any area of BOTW. In fact i usually are between 52fps and my max refresh rate of 60fps at 4k, but I have a potent GPU backing it. At some point especially with triple core recompiling on you simply
in 4k will hit the gpu bottleneck area before you hit the cpu bottleneck area.

Sure on some Intel configs probably a stable 60fps is reachable but then add the price difference as well and ... it comes down on how much you want to spend, but in my opinion it is better to push the money into
a better gpu than cpu if you have limited budget especially if you also do gaming on non emulated games in 4k (where you basically always will be gpu bottlenecked and your gpu always will be the issue). Now atm I really cannot recommend
an AMD gpu for CEMU for known problems (slow opengl drivers and apparently no vulcan port for cemu yet), and on the other hand NVidia cards are rather expensive. But any cent spent on the gpu is basically 5 cent spent on the CPU side
regarding performance gains once you hit a certain point which is basically in the 6 core processor area on both sides. So on the processor side wait til the CES and check what AMD will have to offer with their 2019 lineup. Given that they
will go for 7nm next year, they might give Intel a run for its money.

The only emulator where I can say you have a real advantage with a high end intel cpu is the RPCS3 and only in a handful of games and only because this emulator use an intel only instruction for thread synchronisation
which is marked as unsave but apparently gives a huge speed boost on a handful of games.

As for gaming laptops forget them unless you want to have heat/performance problems and throw the entire thing out in a couple of years instead of gradually upgrading your stuff and saving money along the way.
Also most of the stuff which is branded gaming nowadays is overpriced shiny junk with as many leds possible, charging premium prices for often really shoddy build quality.

I have been burned with a corsair gaming keyboard which had shoddy keycaps for a really premium price and I have seen alienware tests which exposed similar patterns of gaming junkware for the idiots who want to pay too much.
So be warned.


Also one general word regarding laptops have several problems
a) limited space for heat dissipation
b) they should limit their power draw

This usually ends up in well designed laptops with cutting down on performance and adding fans to the system to even get rid of the reduced heat.
In lesser well designed systems you basically will get really loud fans and a processor/gpu combo which rather quickly will thermal throttle to avoid
permanent damage to the hardware. In the end a laptop gaming or non gaming always is a compromise between form factor and performance and power draw.
Of course manufacturers love that people buy laptops because they earn way more on them, once a laptop breaks down, the customer needs to buy another one.

From this angle also comes the trend of less to zero self servicability and often not even be able to replace the battery (which for sure will break down
after 1000 loading cycles).

With normal pcs there is a high degree of self servicability possible (face it building a pc is not harder than building a lego car most people simply do not know that),
although normal pcs you buy prefabricated usually
have small breaking points like non ATX motherboards or weird power supply connectors to prevent that the customers change too much themselves.
(and often their default configurations are really shoddy)
