It looks like L4 cache has the potential to really improve gaming experience. Maybe I will be tempted to upgrade the trusty (but hot) 9900k.

Same old story: Should I buy or should I wait.

There is always new and better stuff on the horizon, so that means waiting forever. The right choice is to buy te best thing available for you, when you need it.

what gives more speed to cpu small L3 and L4 cache or just big L3 cache as is the case of ryzen 7950x3d

There was recently a long, stagnant period of virtually no (worthwhile to upgrade) CPU improvements (post Sandy Bridge). This new era of advancements is the way I like it. Now, within a year or so, our newish CPUs seem a little dated. Awesome!

Yes, absolutely true. But just like what I wrote above, it's truism... so I can only concur. I'm still not sure about what to get though, AMD vs Intel, 7800X3D vs 13700KF? DDR4 vs DDR5? Because nothing really looks like a kick ass buy, nothing really looks bad, and nothing really makes me want to have it, that's the subjective first world issue I tried to softly graze here 😀 The question is highly subjective though, since coming from a 5930K, everything I buy is a major upgrade anyway. 😀

At this point, I would go for DDR5. The price on DDR5 has dropped so much that it makes no sense to go for the older tech. As for the platform, I would go for AM5. AMD plans to have support for it for around 5 years. And if it is as good as AM4, then it's going to be a great investment. You can easily buy into Zen4 today, and later, buy into Zen5 or Zen6 or Zen7, without having to change the whole system. The 7800X3D is the best gaming CPU today. It's performance is top notch, although it doesn't distance itself much from other CPUs. But power efficiency is amazing.

From what I recall when Intel did this last, it didn't make a big difference in CPU performance in most cases but it made the iGPU go from ignorable crap to actually worth using. Intel today still isn't particularly as bottlenecked by memory as AMD is, though, with the asymmetric core configuration, I could see how this may potentially help with that. So - I'd say this isn't going to be as big of a win compared to AMD's V-cache, simply because unlike AMD, Intel doesn't really have a latency or memory bandwidth problem.

It made a world of difference but when it came out all we had was GTX 980 for testing, see how it did on GTX 1080 OC https://www.purepc.pl/test-procesora-intel-core-i5-8600k-rzeznik-zwany-coffee-lake?page=0,14

Like horus said, there`s always something better or cheaper on the horizon, so better to buy it when you want it anyway. Personally, i tend to use my hardware for more than 5/6 years so i can get the best value of it. This also makes upgrades more worthwhile because i know that the performance increase is going to be big after such a long time. For example, when i started thinking about a new GPU, i wanted a card that provided a 50% performance increase. But stuff happened, like crypto, inflation and such, and cards become much more expensive, so i moved my objective from 50 to 100%. My 6950XT provides a 110/120% performance increase over my 1080ti, so objective accomplished. Next in line regarding upgrading is my system platform (CPU+RAM+MB). Right now i have a 7600K that i`m planning on replacing by a 7700X. Not only is the 7700 going to provide much more performance in general, it will also eliminate the bottleneck create by my current CPU when gaming. I`m expecting a 30% increase while gaming with my 6950XT no longer being held back by an old CPU. So, stop with the lame excuses and upgrade your rig!:D

The intel 5775C with the L4 cache was a beast regarding gaming, so i`m also expecting a good showing for meteor lake regarding this aspect, if the rumours are true.

When comparing iGPUs, yes. When using a dGPU, it didn't really stand out compared to anything else Intel had at the time. Sometimes it would top the charts but not by much.

See my comment above, it made a lot of difference but not until tested on later generations of gpus past Maxwell.

You`re probably right, i must be confusing stuff and thinking it works like the 3d parts from AMD. But who knows, maybe they will copy AMD and release something similar.

The L4 cache on the 5775C with ~30ns of latency and 50Gb/s of bandwidth was good, but not amazing. It pretty much had double the bandwidth and half the latency of system memory. It did have 128MB of it, so hit rates were good. But put that cache on one of today's Intel's CPU and it would make go slower. Of course, almost a decade later, Intel will be able to make an L4 cache that is much faster.

Yeah, I am kind of excuses since it's more the limited time I have to build the rig, the "I just threw money at it" approach with today's hardware prizes compared to value, and the lack of anything that's just good, and not just meh with some good, some pretty bad tags attached to it. And like I said, everything coming from my current rig's a gain.. I too expect to see performance increases, even with my 2080Ti if I'd change CPU (like going for Broadwell).

With my 1060 still holding the fort .... I am going for 400% maybe even more 😛 Fun fact I thought my 1060 died last weekend but false alarm still kicking the problem was elsewhere I almost brought a 320 euros 306012gb ... I was not fancing the etc 4070 price the upcoming possible 8gb 4060 made the card an instant no and the 3060ti eventually seems it will loose to the 3060 12gb on newer tittles.... And since I keep my GPUs normally 4-5 years (if there is no crypto rush to delay their retirement ..... On bellow 500 euros only the 3060 was making sense ....

You could look into getting a 5800x3d and mobo for pretty cheap and reuse your memory. It will give you a good couple of years with out too much investment. Save for a GPU.

My personal upgrade policy is simple, at least 100% performance uplift in my typical workloads over what I have now. Unless something is released with a feature I really want, then, as any other enthusiast, all bets are off.

Do not spread rumors and AMD claims (2025 and beyond) should be taken with a grain of salt. Unless there is specific need to pair best CPU with best GPU to play games at low resolution, there is no real reason to buy 3D chip, mainly because next gen CPUs will most likely beat it anyway.

This will be good. I remember 5775c being fast as 6700k just for the L4 cache it had.
