Optimal PC for Blender 2.8

Hello, I am about to build a new PC… My suggestion is this PC set:

CPU: AMD RYZEN 7 2700X
GPU: MSI GeForce GTX 1080 ARMOR 8G OC
RAM: Corsair 32GB KIT DDR4 2666 MHz CL16 Vengeance RGB Series
SSD disk Intel 545s 512GB SSD
HDD WD Blue 500GB
power supply: Fortron Hyper S 600

for price approx: 1 374 USD.

What do you think?

Looks good, but still have some remarks:

Consider investing some in third-party cooling solution, since Wraith Prism is nice, but noisy and does whatever this type of coolers can do.

Ryzen really benefits from faster memory, so consider buying memory at least 3000-3200 mhz https://www.legitreviews.com/ddr4-memory-scaling-performance-with-ryzen-7-2700x-on-the-amd-x470-platform_205154

Why not 2080? Yes, it cost more, but it comparable to 1080ti in usual computation and EVENTUALLY Blender would support RTX, which can be a real benefit, as we can see with Octane: https://twitter.com/OTOY/status/1096659916645818368

Looks like it’s some kind of FSP brand, so maybe there’s a reason to look on more reputable brands with the certification: https://linustechtips.com/main/topic/631048-psu-tier-list-updated/

And what mobo did you choose? PC case? Are you sure that Terabyte of storage would be enough for you?

Thanks for answer. If it is noisy, I am no bother… but it must cool it! :smiley: so… I am no consider any other cooling solution. So… Have a question… if I buy 16 GB with more mhz and after an half or more I buy another 16, it is better than now 32? because I am sure I need 32 but it is no necessary for now. I somewhere listened that RTX isnt support by blender… or Substance Painter… so? IDK in this case. Ehm, what is difference between GTX and RTX? The power supply is shot in the empty space… cause I really dont know what brand or type I can use. MOBO and CASE isnt chosen now. STORAGE: Ye, I am pretty sure, because I dont intend to store many things… just for work is enough. I am open to change every component, if your advices will fit to my maximum budget (1,5k USD)

Cheers :slight_smile:

cpu cooler you can buy later
fast memories are good only in games and only with lower capacity to 16gb, so even 2400mhz will be fine. in rendering it does not matter how fast it is.
I dont think buying rtx is worth its price. 1080 is enough
hard drive could be bigger, at least 1tb

Nah, 32 gb is better option since you can add another 32 later without replacing original sticks. And don’t even think to use singe stick, because you’ll need a dual channel.

For now - yes. As it was pointed out earlier - Octane supports it and you can use Octane with Blender, so it might be a viable option, especially with upcoming free tier for it. Btw, Substance Designer is already supporting it: https://www.allegorithmic.com/blog/new-substance-designer-release-your-life-made-easier
If you are not planning to use this GPU for a very long time, then it might be irrelevant.

For Zen 2 it does

For now I am really confuse about what is good in these days… If you had budget 1.5k USD what components will you choose for happy blending, let say for next 2 years?

I think it will last more that two years :wink:

GPU was switched to 2070 due to budgetary concerns. Thermals of this one looks good: https://www.tomshardware.com/reviews/asus-rog-strix-geforce-rtx-2070-o8g-gaming-gpu,5930-5.html

And it still would outperform 1080

Also you might notice that mobo is on B450 chipset and not on a X470 since MSI’s board seems to be cheapest in this segment, but B450 version have exact the same VRM as X470 one.

Also, if you considering to replace GPU in the future, you might invest $20 on top of the budget and purchase this PSU, so you could fit new ti in it at some point: https://pcpartpicker.com/product/WrNypg/seasonic-focus-plus-gold-650w-80-gold-certified-fully-modular-atx-power-supply-ssr-650fx

Sry, but that is not true. Because of the way infinty fabric works in Ryzen CPU’s I myself could experience speedups from 5 to 15% when comparing 2300 MHz Ram to 3200. I have to admit, that these where very quick tests done yesterday and I have to investigate further over the weekend but there is improvement.

Anyway regarding RAM there is pretty much everything said beforehand. Let me just add, that you shouldn’t buy anything else than something with Samsung B-Die on it or else you will have a hard time to use them at any higher speed than 2300Mhz.

This was the build I went with a few months ago:

Ryzen 2700X (with Wraith Prism cooler. I may upgrade to water later)
32gb RAM
128GB SSD
4TB HDD + 2TB I already owned
RTX 2070

So far I’m happy with it. The only issue is having to manage space on the SSD due to Windows sometimes just randomly using more space.

I have a similar build. R2700 water-cooled using Corsair Hydro100i. Almost no noise even with high stress. Would suggest a Silver/Gold-rated PSU and of-course a spacious case.

so as you showed, mhz in ram does not matter , the difference 3333mhz - 2133mhz is only 3.7 % :slight_smile: so to speak.
Jiri Masak, dont be naive and dont buy the fastest and latest hardware.
Ostapblender, having so fast ram leads to buying better (more expensive) the rest of hardware to work in higher settings due to a couple percent of speed

Blender is not Cinema, and actual testing shows no significant boost like Cinema is experiencing

https://www.anandtech.com/show/12621/memory-scaling-zen-vega-apu-2200g-2400g-ryzen/2

So the RTX GPU is better in performance/price than GTX?

I just made post regarding this in another thread. Please have a look:

If in doubt, you can always just get the speed the CPU is rated for. The Ryzen 2700X spec. sheet shows it is rated to work with RAM around 3 Ghz, so your mileage may vary if you get anything faster.

In addition, the GTX 1080 should still be a pretty good card if you can get one, if not only because of all of the reports of the “Space Invaders” issue on Turing cards and how you almost never hear of people having trouble with Pascal.

Yes of course. But it doesn’t change anything about the fact that RAM speed does matter in rendering.

Hello,
I’ve been looking at my first build with my pcpartpicker list close to what you have in your list. As my build is focused towards 3D printing, I’ve read that it’s possible to forgo the GPU. As this MSI B450 has a HDMI on the board, would a GPU be a nessesity for my build?
Thanks

Threadripper has more CCX’s as such memory scaling should affect it even more.

Based on actual testing, results are +/-1% depending on the scene between slow 2400 and faster 3200.

Blender is more sensitive with core performance then memory, compared to other rendering engines, as such memory speeds have significantly less impact.

Where as gaming shows 10% boost (depending on game of course).

I’m still looking for other benchmarks, but so far I have not found a single one that shows Blender loving faster memory on AMD Ryzen Architecture.

Hm, I only did a quick and dirty test and came to about 5%. I just got the new RAM this week and haven’t fully setup my machine yet . I will investigate further this week and document findings. It’s going to be tedious but interesting.

Technically yes, but keep in mind that rendering and overall experience won’t be as smooth as with dedicated GPU - onboard graphics would be barely able to keep up with what’s going on. If you have absolutely no opportunity to purchase GPU - then go for it. Otherwise it would be better to purchase at least GTX 1050-1060-1650-1660 ti, whatever your budget allows.
