Games are typically not deterministic, which means that there will be subtle differences each run. Add unpredictable network latency to that, and the inputs will end up out of sync.

So yes, it's quite complicated.
That's why you do several runs, and throw out outliers.

Gamer's Nexus supposedly tests WatchDogs2 by running up and down an empty alley for 30 seconds. That will absolutely give you consisted results. They are consistent alright, consistently worthless! If your benchmark isn't indicative of actual gameplay, then it's pointless.

That's not going to help if in one run the input occurs at the right time and a bullet hits, then in the next run it occurs slightly later and misses. Like a butterfly, small differences in input timing will add up to massive differences in outcome.

If you really want automated tests, you either need humans in the loop, who can correct such errors, or you need a deterministic game engine which can record and play back events in-engine.

Normally for MP tests they just join 4-5 games of the same type (conquest etc) on the same map and just average the results. It's really not terribly difficult to do, it's just not a fast way of benching. These guys make money off clicks and views, they want to be the first reviews out so they get the limelight for a longer period of time. Quality content isn't always the main concern for these guys since a lot of them depend on their channels to make enough money to pay rent.

re. multiplayer benchmarks...

is it really beyond the wit of man to have several remote computers send keyboard/mouse scripted actions of "players" in a multi-player environment, as well as have a keyboard/mouse script on the local computer that can allow for a repeated multi-"player" environment for benchmarking?

It can't be much more complicated.

It isn't. Let's just say AutoIT scripts can be used for all sorts of things if you have an image-recognition/OCR module and are reasonably clever about making the inputs seem human-like. Including botting in popular MMOs. If you're really clever, you make it run different raids/runs/quests in a randomized sequence. Running multiple VMs for more instances even. I uh, may have done something like that in the past.

Pity you've already resolved that AdoredTV is indeed Scottish, but there's this TV advert running in the UK about this rather loud (American) sales guy called Captain Obvious, and this is the bit when he overhears some Geordies talking and takes them to be Danish...

EDIT: 20 seconds onwards. The forum doesn't allow time jumps to Youtube clips.

The 6950x is a quad-channel setup and yet consumes 30Watts lower than the 1800x while only being 8fps slower. The 1700x is 4fps faster while consuming 6 watts more. So yeah, "no free lunch," my brother!

You are comparing with a 10 cores at lower clocks.
You have to look at the curve not at a fixed speed to compare.
Summit Ridge does best in efficiency bellow 1V.

The TI NexFETs used on the higher-end boards like the Asus C6H and Asrock Taichi are rated 25A continuous output at 90% efficiency and 40A maximum.

Ok. My data was on a datasheet found on google, of some years ago. I guess that technology has gone ahead...

Sure, but wouldn't that require 64 BF1 accounts though?

I'm sure for acknowledged reviewers, the publishers would happily agree to work with them to use the game as a benchmark. After all, improved user experience means more likelihood of more sales.

In fact, when you think of it, its somewhat surprising the developers don't already make "canned" multiplayer review setups.

Every player on the map would be running from a script - therefore you remove the "AI" out of it.
There is a lot more to it than just AI. Physics engines for instance can yield wildly different results on multiple runs, even given identical inputs. There is often deliberate randomness introduced too, including to things that are significant, like the direction a bullet is fired in. Once enough differences creep in, then the entire rest of the script is invalid.

If we look at the stilt fmax vs V graph there is a liniar correlation all the way up to 3.3GHz. I stlill dont understand it is so high?

Obviously more die mm2 solves a lot of efficiency problems if its prioritized. Also showed for 7700 vs 1700. But we are looking at this as consumers and 6950 is hardly comparable to 1800 or 1700 even if it in this specific workload appears to be the same. Its different price, dev and process cost and - for the most part - performance segments. How would a x399 16c perform for perf and efficiency?

Thats the product that can be compared to a 6950 class products (more likely the hedt skl 12c derivative)

At the end of the day Intel is still focused on high perf designs while AMD went for low power.
That appears to be changing for Intel with first gen 10nm (lower perf than 14++) but remains to be seen how they handle desktop and server in 2019 when they go 10nm+ and those finally make the jump to 10nm. For AMD it would be wise to stick with low power and more cores on 7nm in 2019 and also unleash the ARM version and use the same socket for it.

What happens when games are tuned for Ryzen?
“I’ve always been vocal about taking advantage of every ounce of performance the PC has to offer. That’s why I’m a strong proponent of DirectX 12 and Vulkan® because of the way these APIs allow us to access multiple CPU cores, and that’s why the AMD Ryzen processor has so much potential,” said Stardock and Oxide CEO Brad Wardell. “As good as AMD Ryzen is right now – and it’s remarkably fast – we’ve already seen that we can tweak games like Ashes of the Singularity to take even more advantage of its impressive core count and processing power. AMD Ryzen brings resources to the table that will change what people will come to expect from a PC gaming experience.”

Well, evidently it starts to keep up with Broadwell-E in games too, granted i don't fancy anyone turning his Ryzen into a furnace for the sake of 10% more performance.



That data in no way allows you to draw that (erroneous) conclusion. If you were talking about a construction core based FX processor, then sure. But Ryzen is great in terms of efficiency.
