VS Rendering Times

[pepegota]

i7 8700, 32 Gig ram, GTX 1030 video card, 2 Gig of ram vs i9 9900, 64 Gig ram, Gtx 1060 video card, 6 Gig ram.
I ran a 4k project on both machines with the same settings and timed them.
Results amazing!! i7 time 243 seonds. i9 time 112 seconds. This is more than twice as fast for the i9-117% faster.
i7 CPU temps ran 55-70, mostly in the 60's. i9 temps ran 60-80 evenly distributed between the 60's and 70's.
If you need to deal with 4k video the conclusion is obvious.

Well, it looks good but the conclusion may not be so obvious. And I am assuming your aim was to assess the efficacy (what's best) of the hardware, not the software. On the data, I read that as a vote for the i9-9900 (desktop?) and the related memory sizes and GPU card. But the reality may more or less favourable for that device when other factors are accounted for.
Such as, historically, the main (not only) determinant of processor speed/performance is it's clock speed. Extra factors are the use of hyper threading over multiple cpu's and using lots n lots of RAM. If you can get the paging file totally into RAM (along with everything else) it will really sing. Maybe even an SSD vs HDD installed.

But
- since VS only uses one cpu (let's not rant about why?, again), testing VS on multi-core cpu's should have much the same performance for equivalent clock speeds on those cpu's. And you have not stated what the clock speed of the machines on test are. If the clock speed of the i9 is say 20% faster than that for the i7, there is 20% of your favourable performance difference right there. It's still hardware, but know where the advantage is. In this context, the i9 is probably quite a bit more expensive than the i7. OTOH, if the i7 was faster than the i9, that performance result more than favours the i9 machine and probably would justify in itself any extra cost.
- you haven't stated what version of VS you did the timed test on
- did you have the hardware performance features on or off in the VS you tested with?
- did both machines have SSD? If only one did, then the disk access times for the one with HDD would be especially relevant to that machine during a render (make it work, man!!) test

If you need to deal with 4k video the conclusion is obvious.

Yes it's obvious that VS benefits from the latest high performance CPUs. However unlike many other NLEs, VS doesn't fully leverage the GPU. This means that getting better VS's performance depends on throwing more money at the CPU whilst an expensive GPU remains virtually idle - not a very satisfactory situation for most users.

While you only mention Intel CPUs, undoubtedly, an AMD Ryzen 9 3950X running VS would significantly outperform an Intel Core i9-9900.

One important point I left out was that the i9 was on drive C: and the i7 was on drive D:. That is really the difference between SSD and HD times. Tested on VS 2020.

the i9 was on drive C: and the i7 was on drive D:

What do you mean by stating that you put a CPU on a drive?

Did you overclock one or both of the CPUs? Was VS the sole application running on both systems during your testing? The configurations and test conditions that you used are unclear making your reported results hard to interpret.

No,No,No I just ran the computers as stated. I do not know what you are alluding too with CPU's. I know about the Ryzen computer also.

I think tletter was asking about this statement -- though I think you meant that you had VS 2020 on the C: drive on your i9, and on the D: drive on the i7. However, if that is what you meant, it would be useful if you could clarify whether it was the the i9 or the i7 which had the SSD...

[pepegota]

Sorry for the confusion. The i9 had the SSD and the i7 had the HD.

[Davidk]

On balance then, the i9 is faster, but not by the amount you stated. The i7 was handicapped by having an HDD, a slower overclocked cpu, and only half as much RAM.

[pepegota]

That difference is relative to the equipment tested only. It shows that ram, SSD, clock speed and configuration are important to increase rendering time. For 4k and 360 editing this is a must to reduce rendering time.
