AMD Ryzen 7 5700X

If the CPU does not have the dreaded FCLK 1900 hole depending on what motherboard and memory kit you buy you can easily go over 2000 FCLK with almost any ZEN 3 CPU with two
8GB single rank DIMMS.

Increasing to Dual rank DIMMS will usually make higer FCLK more difficult to achieve but not impossible if you know what settings to change.

The only thing that holds back this RAM kit of mine is the 3600's FCLK:

It can run 1900, but it's unstable at times.

I have similar or same ram posted a few profiles here. We running the similar series B450 boards but ZEN 3 does have better RAM OC VS ZEN 2 etc

This is another Micron Kit I have Crucial Ballistix 3600 CL 16-18-18-38-58 (C9BLM) 16GB DR Micron Rev. E Running ar 4133 CL16-19-19-44-63 1:1:1. Left CCD on Auto it will only boot with 1.2 CCD. This passes at least 5 cycles of TM5 1usmus. I see you are above 2K.. very nice. I am on the fence...

Since I'm watching this thread from the start, but haven't noticed actual 5700X owners comments on max stable FCLK frequency, my question will be obvious: How high FCLK your 5700X can achieve?
I want to upgrade my 3600, and i need to know beforehand. If it can't hit stable at least 1900, it's a real bummer, and I'll gladly consider other options then.

pretty much all zen3 results are the same, maxing out roughly at 3800

the exact clock depends on how many ranks of memory you install, 2x8 will perform like ass but clock higher easily, while 4x2 will require some voltage adjustments to the SoC for sure

Bit blurry but thanks for posting that

Any obvious differences? Dual CCX design with one disabled like some other CPUs had?

So far I cannot tell any differences no, besides the B0 stepping, that being.

I guess they meant to launch the 5700X on CES 2021 and backed off, pushed the (probably little, this is the first instance I find of this) inventory they had into somewhere, and it ended up in retail haha.

My 5700X is B0! The date on the CPU itself is actually 2043 (43th week of 2020).

Validator link: https://valid.x86.fr/cbnkse

Just felt like making (actually, logging into a really old one) an account to say, well, B0 5700X exists, even at retail. I find it weird, as I, myself, don't find any B0 5700X references online and all pictures I find are B2.

I have the box and all, and everything matches up/passes AMD verification as a 5700X. Even most pictures I see of 5700X online have something like 2212 as the date, which makes a lot more sense than 2043, but I can assure you it is 2043, in a kind-of blurry image I took when I got it.

Remarkable. A week 43, 2020 chip is a relatively early Zen 3 sample. It must be one of those 5700X's they manufactured before they went "nah, let's hold onto releasing this until the refresh wave and sell more 5800X's".

I stand corrected, but your processor is very unusual indeed. AMD must have made your batch and then practically halted production until the second wave of Zen 3 chips started to ship, and by then all of the newer units are B2 stepping anyway.

There are no differences between B0 and B2 processors. Clocks, errata, and characteristics are largely expected to be identical according to AMD themselves. It's a manufacturing level change to increase yield, if I had to guess, something to do with the packaging process.

Makes sense. It performs pretty well too, just a bit of PBO adjusting (setting PPT/EDC higher) was enough to make it boost to 4.4GHz and score >15k in CB23

CPU seems to be limited to 120W package power consumption, either by my board or by the CPU itself. It will *not* use more than 120W even if you try to force it (though, doing so is pretty useless, even limiting PPT to 110W is good enough and keeps temps in check)

I guess they didn't wanna sell it back then because... it'd pretty much be a 5800X if you unlocked PBO, except on single-threaded performance (somehow there's no way to make it go over 4670MHz ST). Due to this ST limitation, though, "normal PC usage" power consumption never reaches stupid levels, voltage never goes over 1.32V (I've seen 1.47V on the 5800X just going around in Windows), so I'll take it lol

Covid shortages impacted them and halted that line temporarily, perhaps?

Oh yeah, that would make a lot of sense. Honestly kinda forgot about COVID now, oops.

 

[Dr. Dro]

Covid shortages impacted them and halted that line temporarily, perhaps?

I think they just saw a window to raise ASP since demand went through the roof during lockdowns, and the 800X would sell for more than the 700X while being practically the same processor. By removing the 700X from the equation, they would sell more 800X units and make more money that way. Thus is probably made no business sense to sell them concurrently like they've done with the 3700X and the 3800X.

 

[schumi28tgv]

Yeah, that's a good way to explain it.

I've got a friend with a ryzen 1400 buying my 2700x, he only plays LoL - he cant understand why he gets 144FPS at the start of a match but ~60 at the end, he kept upgrading GPU's but doesn't understand that the CPU has work to do as well.

50% usage to him said the CPU had room to spare, until i explained SMT to him

Hi Mussels,

Can you elaborate what did you explain to your friend , related to only having 50% CPU usage?
I'm kind of in the same situation between going from 1600x to either 5600x or 5700x .
Current GPU is 2060 6GB MSI Gaming X

Thanks!

because task manager is a percentage of all the cores in a system, a single threaded task maxing out on a 5900x is only 4.1%

Thought i chime in, I'm about upgrading my 2600 and basically I was set for 5600 (was waiting past Xmas to see if price will go any further) , but i was just looking at prices of other ryzens and situation is much more favorable to 5700x than it was at review time.

5600 150eur
5600x 180eur
5700G 210eur
5700x 210eur
5800x 260eur

Still 5600 at 150 is best value, though 200 for 8/16 core looks tempting but QHD gaming difference is like 2% so not worth +40% price

Agreed, the 5600 (and the 3600 before it) is the best value for the money.
You also need to pay attention to where the 2% come from. Most tiles gain nothing at all, while a select few will get more than 2% faster with a 5700X. If you happen to play any of the latter, 5700X just might be a better buy. Otherwise, it's 5600 all the way.

Upgrading to the 5600 from the 2600 will definitely get you a massive boost, and later on you still have the option of the 5800X3D.

Massive boost?
At QHD, the 5600 is like 12% faster than 3600X https://www.techpowerup.com/review/amd-ryzen-5-5600/16.html
In turn, that was like 5% faster than the 2600. For me, that (~20%) is the bare minimum to justify an upgrade.

 

[Lordken]

Well, its around +50% isnt it? Or 30% depending how you look at table - the 7600x review happens to have also 2600 in (although its only in summary, not in individual benchmarks)

Also, i plan to pass 2600 to different rig - but I need to get mobo as well, but with current crazy am4 prices not sure when this will happen

that's going to be a large upgrade, any time you're not CPU limited you'll get a good 20% boost (if not more)


Keep in mind the graphs appear different depending on what CPU is at 100% - the scale changes
They also matter depending on the resolution chosen
so if the 5800x is the #1 the performance gap would be larger than if the 5800x was in the middle of the charts

Oh and %faster vs % slower, the values are different - people forget that distinction and think it's "X percent different" when you have to clarify faster or slower
So with that graph you'd have the 2600 at 65.2 and 3600 at 83.6

divide 65.2 by 83.6 for 22.1% slower
or 83.6 by 65.2 28.2% faster


5600 at 90.5 vs 2600 at 65.2

5600 is 38.8% faster
2600 is 72% of the speed (aka 28% slower)

 

[bug]

@Mussels The inconsistency I was talking about is showing the 3600X being significantly faster than the 2600. At the same time the 3600 review says it's about as fast as the 2600. Both times I looked at the QHD results. Since you can't put a piece of paper between 3600 and 3600X, seeing different results is unexpected.

Very likely because the GPU used in those reviews changed in the years between


yep, 2080ti vs 3080

Basically, at ultra settings the 2080ti was the bottleneck there

This is why 720p results are what you should use for comparing different CPU's, since it emulates what they'll behave like on future GPUs

At 720p we see gaps more like what the future GPU results showed - 10% vs 2%

This is also because over time games change, and it's why every few years the games used in the reviews are changed as well. We're into the days where every single game is multi threaded now, for example

 

[bug]

@Mussels Thanks, I was wondering what I have missed (knowing TPU reviews are always thorough). I just didn't have the time to read it all carefully. Even if I'm on a holiday, I still seem to be short of time

 

[Mussels]

All good, worthy questions to ask - and why some people fall right off the wagon with knowledge since they'll check one specific review and then forever assume hardware hasnt changed


my 5800x3D was king of the heap til the 4090 launched, now it's the king of 0.1% lows while the 13900k is the king of maximum FPS

So it's still the king, considering how many people will buy a 4090

 

[Mussels]

So it's still the king, considering how many people will buy a 4090

It's the practical king, with all the conditions that need to be met for the 4090 to reach those high FPS values

I'd rather be able to game at 120Hz knowing i'll never drop below 120FPS, than to game at 240Hz with dips to 45
