Hi Guys,

Planning to build a new Rig with the below specs, what do you think? will there be a bottleneck?

CPU: Ryzen 5 3600
Mobo: MSI B550 Tomahawk
GPU: Sapphire RX 5600XT
RAM: 16GB DDR4 Vengence LPX 3600mhz
Drive: ADATA XPG SX8200 512GB Gen3x4 M2.PCIE or Silicon Power 1TB NVMe Gen4x4 M.2 PCIE
PSU: 650w 80+ Bronze
Case: Cap Ayam with 6 case fans

Thanks for any suggestions and recommendations.

Are you looking to futureproof your machine or something? That board is way overkill for a 3600 (unless you have intention to go for a 5950X in the future) icon_idea.gif

Looks good, but I think for your budget you can get a better PSU hmm.gif

Should be fine for light gaming. Some area of improvement: Mobo, RAM and PSU, especially the PSU.

If you have extra budget, personally, I'd get an Asus or Gigabyte Mobo. Msi isn't bad value wise, but I consider MSI inferior than these 2 brands in terms of mobo quality. Again, you can ignore my advice if you want to go for MSI. You should consider Asrock too coz that's another contender for decent value & feature set (e.g. B550 Steel Legend / B550 Extreme Legend)

My only qualms is the PSU: don't get cheap out on it. It's the heart of ur system and I've experienced first-hand of the consequences in cheaping out on a PSU.

I'd get least 750W  / 850W Gold even if I was on budget. 750W gives you more headroom and future-proof. A good PSU can last you through multiple upgrades/build coz it's the component that can outlast your rig's lifespan (provided it is a good quality PSU).

There is a PSU tier list that you can use for your reference:
PSU Tier List 4.0

If you wish to save money, RAM is the where I'd look at. Getting the 3200mhz is more than enough coz speed wise vs 3600mhz, there is no real world tangible benefit.

However, if you have extra $$$ then stick to 3600mhz coz that is the 'sweet spot' for Ryzen 3000s CPU.

Good luck!

You do not need 750/850W PSUs for futureproofing (unless you intend to go HEDT/RTX3080/90) icon_idea.gif

A decent 550/650W unit will be sufficient for most mainstream PC builds icon_idea.gif

I know, but someone used to raise this; is there an incentive for the PSU makers to put good/premium grade/TOTL materials in a 550W/650W PSU? That's why the pricing for 550W/650W is as what it is.

What's the harm of spending an extra $$$ for a peace of mind smile.gif

This is the one that is pumping life to your entire pc component. And come on, you really don't want 3080/3090/Big Navi 2 in your PC if you can afford one? tongue.gif

Actually there is, but not on the local market: see RM550x/Straight Power 11 550/others icon_idea.gif

There are a lot of top tier 650W units too (XPG Core Reactor/NZXT C650/Super Flower Leadex/others), and a lot of them are even available here too icon_idea.gif

Not really future proof but to enable the GEN4 PCIE capabilities. I was initially look at a B450 board but since B450's are limited to GEN3 PCIE... So I decided that I can spend a bit more for a B550.

Yeah, agreed on the PSU part as advised by bro latios507.. therefore now thinking to get 80+ Gold PSU instead of the initial Bronze.
I did a PSU calculator at beQuiet page, seems that the total power consumption of my new selected specs will be around 337watts. Therefore I initially thought 650w 80+ Bronze will do the trick. As advised by Bro latios507, I will be going 80+ Gold instead now to be safe.
Right? I was really thinking about it... price not that far... might as well put in a bit more for a PC that I hope can last me the next 5 years?

I see, do note that there's no GPU (even Ampere) that can properly utilize PCIe 4.0, and even PCIe 4.0 SSDs offer no meaningful performance upgrade over 3.0 ones icon_idea.gif
Things might change over time though (especially next gen games) icon_idea.gif

Efficiency =! quality, there are some 80+ Gold units that perform worse than less efficient units icon_idea.gif

The 3600 and the 5600 XT are not power hungry at all, and so a decent quality 450W should do the trick just fine icon_idea.gif

If you want something that can last a while, something in the line of the NZXT C650/XPG Core Reactor 650W should be perfect icon_idea.gif

AMD/Distribution mark up 10% noone points this out or complains. Then shops get low stock but want a piece of the cake as well and say must bundle.

At the end of the day ppl still get and all happy with this n follow.

Those that are unhappy won't voice up and it will always continue this way.

Yikes, it seems like AMD has cornered Intel in basically every single aspect (desktop, mobile, HEDT, server/HPC) sweat.gif
...and judging from the rumors of Rocket Lake where the chip only maxes out at 8c/16t doesn't really bode well for Intel either sweat.gif

The nice thing about Zen 3 chips is despite the higher price, you can actually counteract it with cheaper boards (this is the exact opposite of Intel platforms) icon_idea.gif

A 5600X + a cheap B550 board like the B550M Pro4 will be cheaper than a 10600K + Z490, and you still get extra features like PCIe 4.0 (and still faster than the 10600K in many games) icon_idea.gif

It's pretty amazing that now you can build a PC with HEDT-like (or even faster than Intel/older AMD HEDT) performance at much lower cost icon_idea.gif
Even the 1st and 2nd gen Threadrippers look kinda silly to buy right now laugh.gif

Yup, that's why Intel really needs to cut prices on their boards, along with enabling memory overclocking on non-Z boards in order to become competitive with Zen 3 icon_idea.gif

My Corsair H115i Pro doesn't go max speed with Balanced. It will only go max speed with Extreme setting.

My 5900X idles at 45-49C. Load can go up to 82C.

Just to add on a few things:

1. The thermal density of 7nm is quite high, so high operating temps are normal
2. AMD uses a very aggressive boost algorithm to maximize performance, by making full use of its thermal headroom to increase clock speeds
3. The CPU will throttle itself it the CPU gets too hot icon_idea.gif

7nm heat density is why Zen 2 and 3 temps goes up very fast. Intel still 14nm and already producing a volcano.

Wait until Rocket Lake with even more pluses added to their 14nm tongue.gif

https://videocardz.com/newz/intel-rocket-la...t-up-to-5-3-ghz

You know Intel is struggling right now when their future flagship CPU has even less cores/threads than the current one (and half of what the 5950X offers), possibly run hotter and even more power hungry sweat.gif

They need to get out of 14nm ASAP, but that won't happen anytime soon I afraid sweat.gif

Yeah Prime95 is going to toast this CPU for sure with small FFTs.

Pretty sure AMD engineers had thought of that, otherwise they won't consider putting such a large cache on the chip itself tongue.gif

On the other hand the fact that AMD can get 15-20% performance gains out of the same chip by adding a large cache is nothing sort of impressive (those performance gains would be only expected from a new microarchitecture) - it would be even more surprising if the tweaked Zen 3 core somehow manages to outperform Alder Lake in gaming biggrin.gif

From experiencing all the fatal stability and reliability problems first hand, i feel like they dont give much thought on that. Even the 5800x is already overwhelmingly hot for such low powerdraw, cant imagine how much worse it will be by insulating the hot ccx cores with a very hot cache..

I think the only cpu i would be interested is the monolithic cezanne APU.

Wont be surprised if alderlake is behind but since AMD has taken the throne, i stopped being an AMD fan laugh.gif they gave me the impression of being the new intel. I somehow wanna see intel succeed so we can get cheaper high performance cpus.

Well we'll see about that - 2022 could be a very good year for PC hardware enthusiasts, as long as the pandemic and the chip shortage doesn't ruin the party for us biggrin.gif

Hopefully my next upgrade will be whichever the Ryzen with the thicc cache and DDR5.

Interestingly the idea of a large cache on a CPU isn't new - Intel actually did this with the somewhat forgotten i7 5775C, and the performance in some benchmarks is even comparable to a modern day Comet Lake CPU (if the application takes advantage of its larger cache):

Some more tidbits from Anandtech regarding 3D V-Cache:

QUOTE
- This technology will be productized with 7nm Zen 3-based Ryzen processors. Nothing was said about EPYC.

- Those processors will start production at the end of the year. No comment on availability, although Q1 2022 would fit into AMD's regular cadence.

- This V-Cache chiplet is 64 MB of additional L3, with no stepped penalty on latency. The V-Cache is address striped with the normal L3 and can be powered down when not in use. The V-Cache sits on the same power plane as the regular L3.

- The processor with V-Cache is the same z-height as current Zen 3 products - both the core chiplet and the V-Cache are thinned to have an equal z-height as the IOD die for seamless integration

- As the V-Cache is built over the L3 cache on the main CCX, it doesn't sit over any of the hotspots created by the cores and so thermal considerations are less of an issue. The support silicon above the cores is designed to be thermally efficient.

- The V-Cache is a single 64 MB die, and is relatively denser than the normal L3 because it uses SRAM-optimized libraries of TSMC's 7nm process, AMD knows that TSMC can do multiple stacked dies, however AMD is only talking about a 1-High stack at this time which it will bring to market.

Also, as a comparison with the 11400, 5600G has a faster GPU but performs worse overall when using a discrete card. It doesn't make it a worthy buy for gaming systems where folks are holding on to integrated graphics while waiting for RTX prices to drop.
*
To be fair though if you need to game while waiting for a proper GPU, the 5600G isn't too bad, and depending on the motherboard you can move to a proper Zen 3 chip like the 5600X or the 5800X in the future with a BIOS update and a CPU swap (along with a cooler upgrade) icon_idea.gif

If we are lucky enough we might even see the big cached Zen3s to be the last line of CPUs for the AM4 platform icon_idea.gif

While the 11400 is good, the somewhat limited upgradeability and the fact that you need a decent B560 (which isn't cheap by any means compared to B550) just to make proper use of the chip itself (otherwise you'll end up getting 30% less performance) is going to sway some people away from Rocket Lake icon_idea.gif

It's fine though if someone isn't going to upgrade their systems for a long time icon_idea.gif

The undervolt + OC results are interesting hmm.gif

I wonder whether AMD has pushed too much power just for the sake of making benchmarks look good hmm.gif

So far, Zen 4 doesn't seem to be worth the price right now (feels like much of its pricing are early adopter's tax, not to mention board prices and DDR5 RAM) hmm.gif

Yes, that's why when I did my first run I was unimpressed. (as stated in video).

It was until I was doing OC and downvolt where I found it interesting.

Can go DDR5 5200MHz 2x 8GB but do you want to pay twice? smile.gif Can go B650E board with some wait.

BUT my concern is about gains la, the performance level is that of an i9.

I do feel that they did over-do the power, considering I can go from 4.7GHz base to 5.4GHz base and went from 1.25v to 1.2v and still works fine.

My recommendation is to skip 2 generations for upgrade, or if up 1 generation then have to step up on the CPU rank.

That also see what GPU and reso you're on.
*
Guess AMD did took a page out of Intel's playbook sweat.gif

Also somewhat interesting is that if you are only gaming you can basically run the 7950X at ECO mode (aka '65W' mode) and it'll still perform better than a 5950X without power limits icon_idea.gif
Ideally you will want to do some power tuning + undervolting for best results icon_idea.gif

But yeah, Zen 4 isn't very compelling so far (feels more like an introductory chip to the AM5 platform rather than a substantial upgrade over what we have right now) icon_idea.gif

Out of the box ....... meh, personally I feel my i5-12600K is the better all-rounder, thanks to those E-cores.

BUT the E-cores is not without issue, some benchmarks / games actually result in lower FPS when E-cores enabled. Haven't try Windows 11 though.

Did you try E cores on older games? I heard that some older games don't play well with E cores (either they don't run at all or they run very poorly) hmm.gif
