What I would be really curious about (and maybe teethri can educate us there.. I don't have the time to get the data myself): What does the percentage increase in cpu score look like for quad channel systems in-game?
Still, in percentage terms, at least when you're at low MHz, you're getting about 6.8 to 8.7% additional performance per extra stick with the 1920x and 1950x (smaller benefit with the 1900x). The benefit of adding sticks for threadripper seems to be a consistent amount of points that each CPU gains rather than a consistent percentage benefit, so the percent benefit for adding more sticks gets smaller as you go up in MHz and your total score gets higher. Again, for threadripper, adding a stick is roughly equivalent to just going up one big step in MHz (even though for most other processors the benefit of adding a stick is considerably larger than a MHz step; for many, you would have to go from a single 2133 stick to a single 3000 or 3200 stick for it to be better than two 2133 sticks), and the number of extra points of performance each CPU gets from extra MHz is basically a CPU-specific multiple of the number of extra MHz.
I willl confess to not having played around with threadripper benchmarking myself; I'm playing with a spreadsheet of Wow Actual's numbers.
That's how much it increases your CPU component score; as described above, that's only about 15% of your total 3DMark score when the CPU and GPU scores are equal. If you slant the build toward GPU, as you should if 3DMark is your focus, the importance ratio changes from .15 to .85 to something more like 36.56% versus 63.44% when measuring how big the effect of a certain number of extra points to each component score is (meaning that GPU is still more important, but less than twice as important). Or, the CPU to GPU importance ratio is 24.18% to 75.82% in terms of the relative importance of raising a component score by a certain percentage of what that score already is (meaning that if the GPU score is already larger we're looking at a proportionate increase, so the GPU increase is 3 times as important in the percent effect on the total score but it's a bigger increase). This is due to the way the harmonic mean reflects CPU bottlenecking, and is based on the 62.04% / 112.11% numbers in the first post.
I posted in Snuke's thread about "Formula that calculates CPU score with ram impact" about the role of RAM frequency as well. I focused on frequency there, even though for most CPUs (threadripper not included) adding a second stick usually makes a bigger difference than one or even three incremental MHz boosts.
It was made for version v0.8.6.1 (like the title implies)
And we are now in v1.3.1
So I don't know how much of your post is related to variations in numbers between the v0.8.6.1 & v1.3.1, but you should really, if you want to look for things, use BiuBiu's calculator that is up to date
https://steamcommunity.com/sharedfiles/filedetails/?id=1596577871
Way faster in spitting results than the sheet you're using (that I used in the past too btw, when it was up to date)
And the link to BiuBiu's thread in case you want to communicate mistakes and such

Well, the first comment was about the equation for determining total 3DMark score from the component scores, which is based on the actual Time Spy scoring system, so the difference between game versions should have almost no bearing on what I said in the first comment. The only things it would affect are the part where I briefly mentioned the 3DMark score for the Celeron 3930, and whether or not my estimate that it would cost around 1.72 or 1.735 times as much to raise GPU score as CPU score is in the ballpark. For my later comments that got more specific about how RAM affects CPU score, the difference in game versions could be more important.
But with your thing about value of upgrading CPU vs GPU... just remember that, later game, when you unlock GPU tuner and can OC GPU, as you can push them way more than CPU OC, and due to their 85% "weight" of the score, all that value thing just goes to trash nope ???
I mean, you can be happy if you oc a CPU with +400MHz, so the impact on the score is still "limited", while on the other hand, you can go so much higer with GPU's and thus their cost vs price when OC is totally crushing CPU's nope ? I mean, I always looked at CPU's to just not penalize too much the score when you need to reach a given benchmark score.
Again, it's just a question I offer to you, and that's just to add "fuel" to your thinking, but I don't need an answer for me, as :
- I'm not a math guy
- Budgets are now so ridiculously high, I just don't see the point of saving on costs for the few hundreds you can save early game, and that anyway don't go into your bank account.
So again, for my "limited" undertsanding in your math, while I applaud the effort of your calculations and typing, I just don't see a use for me in game, and also nor do I see a use for the higest benchmarck scores, as it's more about binning known parts, due to silicon lottery, than understanding how much this or that "lower" tier parts could impact this or that score for a few hundreds of points.
**************************************************
Also, you can clerely see here in my comments, I have a slight "issue" understanding mybe 1/5 of your initial post, while your title is...
How 3DMark works: Simplified....
simplified... really ?
To me simplified means :
GPU score = 85% of the benchmark score
CPU + RAM impact = 15% of the benchmark score
The higher RAM speed I can use will give my base CPU score a few more points (and as it's exponantial with the CPU score, with low scores CPU, no need to go crazy on RAM speed, as it will still be limited, nor do I need an expansive Mobo that can give me better RAM max speed)
So the quickest and simpliest way to increase benchmark score to a SIGNIFICANTLY higher score = a GPU upgrade.
END
That's simplified to me.
**************************************************
Also I'm still at loss with you saying that :
Because to me, you are probably very right if you build everything from scratch, but nowhere in your post you mention if all your theory is about overall gameplay, or only "new build" theory build.
So due to the fact that, when you have a given CPU "architecture", let's say a Kaby Lake, you are limited to a CPU that will have a max base score of 4886 with a single RAM stick of 2133MHz.
Then if you want to have a better CPU score (stil with 1x 2133MHz RAM stick reference), you need to swap the Mobo as well... Adding to the cost.
So example of a possible mid game upgrade job
I have a build, with a :
Mortoni H170 Mtech (limited to 2666MHz RAM speed)
A single RAM stick of 2133MHz
An Intel Celeron G3930
A MSI GeForce GTX 960 GAMING 4G
Score of the build
CPU score : 1392
GPU score : 2225
Total score : 2041
Est. Wattage : 368
Now let's say the game asks me to upgrade that PC to a 2422
Now to reach that score you need an Intel Core i7-7700K = $270
But to reach said score a GPU of $265 does the job, like a MSI GeForce GTX 970 GAMING 4G for a total score of 2674.
So in this example the upgrade for a given target is $5 cheaper the the CPU upgrade. Specially since the GPU becomes the bottleneck if not upgraded.
Then with that same example you come to a bottleneck point, where if you're not upgrading the mobo, you will be still very limited to a 5456 score for the CPU, no matter what, due to the limitation of the RAM speed of Mobo, and the best Kaby Lake CPU possible.
When you have upgrade jobs, it's so situational that I porobably don't need so many calculations as yours to understand that :
If it's the original GPU that will bottleneck the overall score (like a stupid 1050), due to it's "weight" in calculation, I have no better choice than to upgrade GPU, or my "$ value" from CPU upgrade will be completely negated by the GPU. (just like in my previous practical example)
If the CPU is a VERY low end CPU, and I need to raise TOTAL score by about 20 points, indeed I can probably get my score with a second RAM stick and/or quicker RAM.
If I need to raise total score by +100pts to +300pts, probably a better CPU will make it.
If I need a score increase that goes from +500 and higher, I probably will get there with the GPU upgrade.
SINGLE GPU scores are never impacted by the Mobo, while on the opposite, CPU scores are very dependent of Mobo (OC able for CPU IF CPU is unlocked for Intel, so yeah, there is also that... AMD or Intel build ? Why ? Then all AMD mobo are limited to a max 3600MHz Ram speed in game), the mobo will cap the max RAM speed too.
So again, if upgrade jobs, it's so situational of original customer's PC build, that so often you are probably better of simply don't care much and upgrade GPU anyway, specially now that budgets are a NON limiting factor, you have NO incentive to spare a few hundreds on builds and upgrades (as your only income is anyway only labour)
So as the game is as much about upgrading as building new from scratch, I feel (again, FEEL, because honnestly I don't understand 1/5 of your original post I think ?) your text is more a "theory in a vaccum" that works probably 100% if building from scratch, but has it's limitations when it comes to upgrading.
Only thing I know, I have never "overthought" the game, even when budgets were WAY tighter than they are now, I had no issues building and upgrading within budgets, and once more, as your ONLY INCOME is from labour, I hardly see a use of "penny pinching" for this game, and moreover now that budgets have been stupidly raised to an unchallenging level of any sorts.
When Budgets were tight, you always had 2 requests possible for upgrades, aka, install AIO or more RAM and then a given better score.
The trick was to always buy the CHEAPEST request (AIO or RAM) and then deduct that from parts budget, and buy the best available GPU with remaining budget. That never ever failed me to reach the target requested score.
Sorry for wall of text, and again, it's just fuel for your thoughts, no need to try to explain me more, because I probably will not understand half of what you say XD
G = .85CT / (C - .15T)
Or
C = .15GT / (G-.85T)
So if you know that you're keeping a Ryzen 1600 and just need a GPU upgrade, and you know the CPU component score for that Ryzen, you can just multiply .85 times the target total score times that CPU score, divided by the CPU score minus .15 times the target total score, and that's what your GPU score needs to be.
I agree that having a guide on how to penny pinch builds that target benchmarks in this game may not be necessary, since consumer budgets tend to be way bigger than necessary.
As I mentioned in Reply #2, although the GPU is 85% of the score when the two scores are equal, if your build is already slanted toward GPU, increasing the GPU score further may only account for 63% of the amount of potential increase you can get by increasing the subscores, not 85%.
Once you reach level 18 and unlock the GIGABYTE B450 AORUS M
, which is a low-cost AM4 motherboard that allows multi-GPU support, literally EVERY target score between 3606 and 16239 is achieved most cheaply by using that motherboard, a Ryzen (which is what that motherboard is for), and a dual graphics card solution. Now, there are some caveats here. First, this is only considering CPU, GPU, motherboard, and RAM cost, not power supply or case fan cost, so that's obviously going to bias the results toward multi-GPU solutions. Second, at the extreme high end, you might need some graphics cards that are not available at level 18, like the AORUS 2080 you get at level 25 or an 11 gigabyte version of the 1080 that you get at level 21. But even with the pro multi GPU bias of not considering PSU costs, I was stunned that, as far as I can tell, every target score in that range is achieved most cheaply with Ryzen and a dual graphics card solution. In many cases, you can still get the exact same score with the exact same CPU, GPU pair, and RAM without that motherboard at a higher price before level 18 with a different motherboard that supports multi-GPU, but I haven't checked whether it's still the cheapest option. I haven't actually checked every score in that range, but I did check every budget from 565 to 1435 (as the budget for the parts included in this comparison), and it always comes up Ryzen and double graphics card. Jumping up to higher budgets like 2085 and 2705, it's still Ryzen and double graphics card.
For example:
AMD Ryzen 3 Quad Core 1200 1 RAM 2133 DFL Radeon R9 280 GR8 3G 2 GPU GIGABYTE B450 AORUS M Mortoni Value Supreme 2GB 2133 Mhz 565 Cost 465 Watts Score 3724 Level 18
You don't have to worry about your client's electricity cost, but I'm pretty sure that once you factor in PSU and case fans, using two graphics cards versus one is basically break even.
Most of the target scores of 3605 or lower can be achieved at the same cost at any level that is 5 or higher (as in, the cheapest build and its cost does not change as you level up once you've reached level 5) and involve using a Celeron or Pentium.
