This I am aware of. But it closes the gaps for the chips that don't have vcache. Hence my point in my prior post.
| Captain_Yuri said: You are also not looking at the cost factor and the early adopter tax. AM5 and DDR5 are both new platforms which means they have a high price if you want them and the result is only 10-15% increase in CPU performance if you go with Zen 4. Where as if he spends $320 and gets 5800X3D + X570, he can wait till AMD has a CPU that's 60-70% faster than his current CPU. The benefit by that point is AM5 motherboards will be cheap and DDR5 will also be cheap and he gets a huge boost in CPU performance instead of paying the early adopter tax while enjoying a significantly faster gaming performance by going with a 4080 instead of 4070. |
Again. Long term costs.
Buying AM5+DDR5 may not be more expensive than buying AM4+X5800X3D+The next platform.
That is the point I am making here.
| Captain_Yuri said: "Gaming performance is where the 5800X3D takes a front and center role, with a few instances of 50% performance lead, but most games are closer." They are closer but the gap is still huge. The only one that's close is GTA V and I am sure that one is running into a GPU limitation or Engine limitation. But all of these are old games and not counting the new Ray Tracing performance hit that a 3950X will get killed at because while Zen 2 was good for it's time, isn't aging very well in gaming. 3950x vs 5800X3D from your link: Civilization VI: 127 vs 188 And sure, a 3950x might be cheap but now he has to spend money on higher tier Ram where as with 5800X3D, he doesn't. |
Not a single one of those games is under 120fps. That makes the 3950X is fine.
He may not have to spend money on better Ram.
Again, it's making those assessments to make the best bang-for-buck choice, the market is littered with fantastic products, it doesn't start and stop with the 5800X3D.
Weigh your options.

Sure there are areas where a 3950x is better at but a lot of Transcoding/encoding/modelling/art stuff can all be done by the 4080 thanks to CUDA acceleration which is in majority of the programs these days and can be done much faster than a 3950x. GN did plenty of videos about this where you don't need a high core count CPU for a lot of tasks as long as you have a good GPU. I am not denying the fact that there are certain areas that a higher core count CPU will be better in but so far, he hasn't indicated anything that would suggest he needs high core count CPU over a strong gaming CPU to power the 4080. Cause a 3950X will absolutely hold the 4080 back compared to a 5800X3D. |
Both CPU's will be fine. I am not suggesting he *has* to upgrade to the 3950X, just suggesting it as an option.
Just like AM5+DDR5 is another option.
And just like sticking with his current CPU and overclocking it hard is another option.
GPU transcoding/encoding/art stuff has been around for decades... And for over a decade, they have been GPU accelerated, but anyone who has a high-core count CPU like myself, knows the GPU can't do everything yet.
The advantage of high-core count CPU's is especially prevalent when you are doing tasks other than just gaming... Or when games start to get heavier threading support. (Which is happening, 6-cores are regarded as minimum now in terms of thread counts.)
If you are buying an RTX 4080 or better, then we must assume that 4k is going to be the target resolution, otherwise that is wasted hardware.
And from there, the CPU becomes even less relevant as you will be GPU bound anyway.

A lot of factors coming into play.
Inflation is causing commodities to rise in price (That means Ram), plus reduced manufacturing as fabs start to retool and shift to DDR5... And still relatively high demand causing supply/demand price pressures.
Back in my day you could get 16GB of DDR3 for 60 bucks AUD. Cheapest DDR4 is $85.
Still not the heights we saw during the middle of the pandemic or during the great Ram shortage a good 4-5 years back, but not super crazy either.
