ok so after effects uses single core, what cpu is out there that is so powerfull to make magic out of it so i do not se lag when effects is applied to composition.
after effects is a good software but when it comes to preview it sucks big time.
sony vegas ,premier pro drag drop and play it previews without waiting to render.
Well it isn't really single core. It just isn't optimized to be able to run on all cores, so having more cores has very little effect on performance(from what research I did). Here's a diagramme from PugetSystems that I linked earlier:
The 24 core Threadripper 3960X costs
1350 USD with the best performance in Adobe After Effects
The 10 core i9-10900K comes in at
775 USD, out of stock at 530 USD, with the KF variant coming in at
530 USD
the F refers to it not coming with integrated graphics. In theory, this shouldn't affect performance, in fact it should boost performance by reducing heat output(even if so slightly), but the KF actually
falls slightly behind
The 8 core i7-10700K starts to be a little more competitive for Adobe After Effects, coming in at
394 USD
Since your dying to hear this one, the 8 core i9-9900K comes in at
390 USD. It's most comparable alternative is the similarly cored i7-10700K, which offers
nearly identical performance. Before you start to jump at the i9-9900K, remember that it's an older card, which doesn't seem like a big deal, but it certainly won't be doing you any favors.
Now here's the juicy part. The 8 core Ryzen 7 3700X comes in at
290 USD with very comparable performance to the 8 core intel alternatives, but actually loses heavily on benchmarks(
vs i7-10700K and
vs i9-9900K). Now on paper, it should be shredded(see what I did there lol) but it seems to have near identical performance in the diagramme above.
The more similarly priced Ryzen 7 3800X comes in at
340 USD, seems to be just
marginally better than the 3700X on paper and on the diagramme above.
So now, I'd say for Threadrippers, the 24 core TR 3960X will do you the best. The 32 core 3990X actually falls way below anything listed above. For AMD CPUs, the Ryzen 7 3700X will be your best bang for buck on Adobe AE. The
430 USD Ryzen 3900X will be your best mid-end AMD CPU, with performance that actually
falls behind the i7-10700K, priced at
394 USD. However, on anything higher than 8 core, the 3900X will melt the poor thing away, having 150% the amount of cores. Am I a little biased towards AMD? Yes, but I'm trying to just lay the info out to you, unbiased(and certainly unchanged). I'm linking all of my UserBenchmarks and all of my PCPartPicker prices.
In conclusion, I'd recommend the Ryzen 9 3900X as your mid-range workstation processor. Its 12 cores will do you alright for most workstation tasks(however the 3950Xs 16 cores might do you some favours).
The TR 3960X becomes your king for a mostly Adobe After Effects and some all-core rendering workstation CPU.
The i7-10700K takes the crown for Adobe After Effects(with a little bit of other tasks). It falls in an awkward position, where if you want to handle all-core workstation tasks, the Ryzen 9 3900X(or the 16 core 3950X) becomes the obvious choice, but if you just want raw price to performance on Adobe After Effects, the 3700X will be your best bet.
The Ryzen 7 3700X takes the crown for absolute budget JUST Adobe After Effects.
And the TR 3990X becomes your king of I literally have no budget and I'm not too concerned about Adobe After Effects, just all-core performance. Maybe a TR 3970X or 3980X will be a decent middleman since at
3600 USD, The TR 3990X becomes too expensive for to justify its (relatively) lackluster performance. I just see it as a flag-ship CPU that isn't really practical for nearly all workstation users. Granted, it does have over double the cores of the 3960X, so it does have it's moments I guess.
In conclusion of the conclusion, the Ryzen 9 3900X or the 3950X seems to be your best option. Just remember that the performance and cost of the CPU isn't everything. Now the benchmarks will reflect the performance of the CPU with the average pick of motherboard, but the prices won't reflect the cost of the motherboard(and other features of the CPU, like max RAM, PCIe lanes, etc). Now the Ryzen 9s and 7s can be held similarly to the Intel 7s and 9s in max RAM and motherboard cost, but the Threadrippers are nothing close to either.
I sprained my wrist earlier in the day, so typing this was an absolute pain, hope I could help!
