DerBauer hardware survey highlights issues with max boost clock on Ryzen 3000 "It's worse than I thought"

Recommended Posts

I don't really know what to say, to be honest. The results is much worse than what I expected. Again, keep in mind what I said at the beginning, [in regards] to being a public survey what can be the negative influence about this but I am pretty sure that I was not wrong, that the CPU's in general cannot hit the boost and probably its just the silicone quality is maybe not good enough. I clearly want to state that I absolutely recommend buying those CPU's...

Although this doesn't change the overall value of Ryzen 3000 in my view and its more relevant on the higher chips (3900X in particular), one should be aware what you are buying. Up to this point the "boosts up to XXX" has been a fairly reliable numbers, but AMD is changing the equation here by not consistently reaching it and it seems unlikely that changes will be made (in bios and such) to correct it due to risk of chip failures in the field.

Update: AMD has released a statement on twitter:

"AMD is pleased with the strong momentum of 3rd Gen AMD Ryzen ™ processors in the PC enthusiast and gaming communities. 3rd Gen AMD Ryzen users are reporting boost clock speeds below the expected processor boost frequency. While processor boost frequency is dependent on many variables including workload, system design, and cooling solution, we have identified the feedback from our customers and have identified it as having an impact on our firmware. We are in the process of preparing a BIOS update for our motherboard partners that addresses that issue and includes additional boost performance optimizations. We want to provide an update on September 10 to the community regarding the availability of the BIOS."

AMD should have just advertised the clockspeeds as 100Mhz lower. People are happy with the performance which is what matters.

 

What is the point of this? Do they think that they will lose sales because some people don't unerstand that clockspeed is only one factor in performance.

This is probably a complicated answer. Perhaps they didn't have the right data of production lot performance at the time they decided the marketing issues. Alternatively, between Intel's traditional higher clock speeds and trying to make 3000 series look better than their own 2000 series and make a big splash, they may have simply over-committed on the marketing aspects of boost clocks.

What I understand so far is that even though Ryzen has a fairly low TDP and runs cool on a stock cooler, the boost clocks are still dependent on cooling. So if you have good cooling they will boost a bit more.

So AMD should be advertising boost clocks based on averages using the stock cooler, otherwise its a bit misleading if boost clocks aren't consistent.

I smell another Bulldozer class action lawsuit. Heck, there was a class action (several actually) about lawn mowers not doing the advertised horsepower.

Unfortunately I think AMD will get away with this because the chips tend to hit the boost frequencies in certain ideal conditions... i.e. particular applications when running with good coolers.

I also suspect that all the marketing probably says "...up to XXX Ghz" giving themselves some room.

Sauron'stm Product Scores:

Spoiler

Just a list of my personal scores for some products, in no particular order, with brief comments. I just got the idea to do them so they aren't many for now :)

Don't take these as complete reviews or final truths - they are just my personal impressions on products I may or may not have used, summed up in a couple of sentences and a rough score. All scores take into account the unit's price and time of release, heavily so, therefore don't expect absolute performance to be reflected here.

 

-Lenovo Thinkpad X220 - [8/10]

Spoiler

A durable and reliable machine that is relatively lightweight, has all the hardware it needs to never feel sluggish and has a great IPS matte screen. Downsides are mostly due to its age, most notably the screen resolution of 1366x768 and usb 2.0 ports.

 

-Apple Macbook (2015) - [Garbage -/10]

Spoiler

From my perspective, this product has no redeeming factors given its price and the competition. It is underpowered, overpriced, impractical due to its single port and is made redundant even by Apple's own iPad pro line.

 

-OnePlus X - [7/10]

Spoiler

A good phone for the price. It does everything I (and most people) need without being sluggish and has no particularly bad flaws. The lack of recent software updates and relatively barebones feature kit (most notably the lack of 5GHz wifi, biometric sensors and backlight for the capacitive buttons) prevent it from being exceptional.

 

-Microsoft Surface Book 2 - [Garbage - -/10]

Spoiler

Overpriced and rushed, offers nothing notable compared to the competition, doesn't come with an adequate charger despite the premium price. Worse than the Macbook for not even offering the small plus sides of having macOS. Buy a Razer Blade if you want high performance in a (relatively) light package.

 

-Intel Core i7 2600/k - [9/10]

Spoiler

Quite possibly Intel's best product launch ever. It had all the bleeding edge features of the time, it came with a very significant performance improvement over its predecessor and it had a soldered heatspreader, allowing for efficient cooling and great overclocking. Even the "locked" version could be overclocked through the multiplier within (quite reasonable) limits.

 

-Apple iPad Pro - [5/10]

Spoiler

A pretty good product, sunk by its price (plus the extra cost of the physical keyboard and the pencil). Buy it if you don't mind the Apple tax and are looking for a very light office machine with an excellent digitizer. Particularly good for rich students. Bad for cheap tinkerers like myself.

      • 4.575 from 92 users (13.43%, 7.1x from claim)
      • AMD has some explaining to do.

I'd say "always wait for reviews", but in this case it took a public survey to really show all these ._.

 

EDIT: to be clear, I personally (PERSONALLY) don't mind a full 0.1 ghz difference at those speeds, but yeah ._.

Given that everyone uses the same mobo and runs their PC in the same ambient temp, this it outrageous.


Awareness is key. Never enough, even in the face of futility. Speak the truth as if you may never get to say it again. This world is full of ugly. Change it they say. The only way is to reveal the ugly. To change the truth you must first acknowledge it. Never pretend it isn't there. Never bend the knee.

The survey itself is flawed since people aren't running the same cooling, power delivery and firmware. A lawsuit is not possible. AMD have listed a given boost, not what users need to achieve it. If someone is complaining about getting 100MHz lower on a cheap 45$ B350 board, then that's their problem

I think this one's easy. If AMD were careful to say "up to x GHz", they're 100% safe. If they didn't, they need to hire a new marketing manager.

"up to" is one of the most intentionally misleading marketing phrases that is widely used, not just by AMD. It's a way of looking like you're giving useful information when you're really not, as it could be anything lower.

My personal opinion is that AMD should restrict their boost numbers to what can reasonably be achieved with stock cooling, then clarify higher boost available dependant on cooling solution used.

 

That said, these numbers are so close that I'm not going to hassle them over it.  Also, this is based on an informal, unscientific survey, so I take those results with a grain of salt.

AMD should post 4GHz as boost clock and then everyone would be shitting their pants when CPU would be hitting 4.4GHz... That's kinda like what NVIDIA is doing. Stating absolutely pointless boost clocks and then GPU always goes kilometers past that mark. Coz in this case, AMD's "Max boost clock" makes more sense. It's a number which will NEVER be exceeded by the CPU. Getting as close to it as possible falls down to many factors and none of which are made up by AMD. TDP, temperature, threads used for the workload, all this affects the clock.

 

It's kinda ironic how people always want MOAR CORES, AMD gives them MOAR CORES and then they start bitching it's not running at 4.6GHz at all times. Especially in this time and age when everyone wants everything as multithreaded as possible. Newsflash, you can't put load on all cores and expect them to run at 50GHz. But you'd also want that 105W TDP at the same time. You know, I'd love to break laws of thermodynamics too. Overclocking would be so much easier without these stupid restricting laws. What idiot made them up anyway?

Define it in a more meaningful way. Maybe something like "average CPU speed" which will no doubt lead to endless arguments as to what should go into that average. Minimum could be useful in some situations, but we have that already as base clock.

 

With Zen 2, it really feels like AMD went all out pushing the single core turbo so that can advertise higher speeds.

They sell the CPU with a specified base clock which all cores on all processors will run at on motherboards built to minimum specifications. The boost clock is dependant on so many factors that the "up to" term is used. If the bare minimum PSU is a 350W and a 350w is used, then it may sag under the extra loading of jacking up the speed and cause instability. The only way they can market guarenteed speeds is to lock the CPU and what you get is what you get.

AMD will be fine. Every chip can hit the "max boost", emphasis on "max" here. AMD never said you could all-core sustain at that boost, nor did they ever say anything beyond that the chip could hit those clocks. If you load up very specific types of single-core workloads, you'll hit the boost without much issue. Anything that hits AVX you won't see it, however. Plus, a lot of motherboards have less aggressive single-core boost effects in their power tables.

 

Currently, your max boost matters what Motherboard & BIOS you have. Chips will still hit the all-core speeds without much issue.
