Pretty substantiated or unsubstantiated! Up to you to decide!

"However the leak suggests IPC improvements will be less than the expected 20% hinted at by AMD and may end up being closer to 10 - 15%. The leak also claims that L3 cache will remain at 32 MB however it will no longer be split due to the single CCX. While this may be disappointing for some, remember to take the claims with a grain of salt as with any rumor."

Well I guess one day, in 10 years, I'll upgrade my 5ghz 9900k to something that is 500% faster. It's probably going to be viable in 2030 anyway.

If they can get a 15% IPC improvement and a 5% bump in clock speeds why would anyone be mad?

But tbh, fuck adored. So many of his rumors are way off base. AMD has actually delivered on their performance promises for ryzen, zen +, zen 2, and navi so I'll wait to hear their performance projections.

10-15% IPC improvement is more than budging the needle, especially paired with clock frequency increases. An 8 core 65W Zen 3 would be a hell of a base for a media server - not so many threads they can't be leveraged in transcoding, and high clocks and performance per watt.

Never such thing as too many threads for transcoding. Unless you like to do them one at a time...

What is more important for overall game performance than IPC increase, is how they will be able to bring down the latencies.

Right now, I would be happy with a desktop 7nm Zen 2-based 8C/16T processor with Vega igpu. it would make a great compact ITX media server.

Guilty as charged - on my Ryzen 1700 server I frequently just queue up a gaggle of rips, then walk away and let it grind for a while. Limiting thread usage per encode and running two queues at a time on my 7940x is standard practice when I've got a bunch to get through, but setting that up is twiddly and I don't usually have a half-dozen movies ready to encode at a time. But right now, working from home with my Blu-ray binder sitting a few feet away, that's more tempting...

Same boat here. The idea of spending a lot of $ for basically just a higher cinebench score is not vaulting me over the fascination threshold. CPUs are at the point where it's diminishing returns; rather put the money into 3080Ti or Valve Index.

However: Mobile Ryzen 4000 looks very cool and will prob be my next laptop

A good IPC bump is needed, not that the CPUs are slow currently. A clock boost plus a solid 10-15% IPC boost across the board would be great. IMO, more important than more cores currently. But playing around with Handbrake and H265, you would certainly benefit a lot from going to a higher end platform with more cores. A 12 core 24 thread CPU in the mainstream socket would be nice to have in a few years.

Is that not what we have now?

the 3900 and 3950 are mainstream socket with 12 and 16 cores.

but yeh the 4600 going 8 core and 4700 and 4800 going 12 core would be awesome, but doubtful with the lack of competition.

Since AMD already matches/beats Intel in IPC, getting a 10-15% increase is respectable. The problem is Intel has the clock speed advantage over AMD. Once AMD can get clocks close to Intel, then in my eyes it would be a huge game changer.

Of course rumors are...well taken with a grain of salt.

I hope so. I'm eyeing a Ryzen system upgrade at some point. However, games being what they are, I still need really good per-thread performance. Plenty of games, particularly Elder Scrolls Online in my case, are reliant on a single main thread. While they are multi-threaded, that one main thread is the bottleneck so you need high per core performance for it. Adding more cores doesn't get you anything.

I'm hoping they'll make something that gives a non-trivial per-core boost over my 8700k @4.6GHz. IF so, I'll probably buy one... Assuming I don't lose my job in the upcoming economic depression ><

Well considering AMD has matched/beat Intel in single core performance you could get a Ryzen 3000, since you only have your 8700k at 4.6ghz. BUT, that would barely be an upgrade right now, so you are good to go. Wait for Ryzen 4000 or even intel's upcoming rumored 10nm products.

Because right now there isnt a game out there that needs more than a 8700k imo.

Ya I will only upgrade if it looks like there's something to gain that is non-trivial. Also depends on how the new thing handles clocks, my 8700 is 4.6GHz all the time, all cores loaded with AVX2. I've noticed new CPUs have a trend of having a lot of CPU offsets which may look impressive, but is not useful since games (and other things I use) run AVX and do hit more than one core. So if a CPU does 5GHz single core, no-AVX, but then downclocks to 4.2GHz when actually running real software, that doesn't get me much.

So I have eyes on the Ryzen 4000. We'll see what happens with it.

As I said the main game that needs it currently is ESO. That rarely, if ever, maxes my GPU and nowhere near loads up the CPU. What it does is load up a single core, and that is limiting everything else. If I can boost that core speed, the game runs faster. My goal with my system, which I don't often reach but still my goal, is to have games refresh rate limited, not CPU or GPU limited.

Personally waiting on Ryzen 4000 since the 3000's came out. Really hope they can knock it out of the park even more, then I can finally retire my 5930k

4.2 all core seems about where it's at on Zen 2 for the lower-core parts. Not quite as fast as Intel but closing the gap.

I'm just hoping that DDR4 will still be an option when this comes out. I'll be looking to upgrade and I'd rather not buy new ram if I don't have to. 32GB of DDR4 at 3200Mhz should be fine for quite some time to come.

Heh I was thinking the same. I’d hate for that to be a reason it becomes hampered though.

Everything I've seen suggests that it will still be AM4 and the next round after it will switch to a new platform.

This should be AM4 and our 3000 supporting boards should be good to go. It will be the chip after this one that brings DDR5 and perhaps PCI5 as well... and I think with everything going on that probably isn't happening till late 2021 or even 2022 at this point.

I know I look forward to being able to take my 3600 slot it in a budget build for the wife or one of the kids... and slot me a 4700, would be fantastic if it ends up being a 12 core part, but 8 core with 20% more performance per core through a combo of clock and IPC sounds great to my ears.

An Nvidia Shield makes a great media server...

I get why transcoding on the CPU is a thing right now, but I'd hope that it would generally be used for 'archival' transcodes. It would be nice to use GPU resources for streaming transcodes where necessary as it's so much more efficient all around.

Anything more than 10% improvement ON DESKTOP is impressive at this point.
When can we expect desktop parts? It feels like all the attention is on mobile.

it will be, ddr5 at the earliest for consumers will be 2022.

I hope to see more Desktop parts soon. Mobile parts are frankly a quandary - I know mobile devices (including laptops) are getting more popular but in general it is for the " basic use" demographic. Thus, its split between the ARM processor setups etc... to the point I'm not sure if x86 laptops, especially performance ones are really going to be a big market segment. I mean its all well and good for them to improve on mobile and I'd like to see AMD mobile parts with more cores and more per-core performance than Intel's general mobile stuff, but ultimately it seems like desktop is a larger demographic for these kinds of processors.

The 3950x is 10% behind 9900k in low-threading games, and faster in everything else. a 15% IPC increase plus 5% clcok bump would exceed inlet's new 5.3 GHz 10-core Skylake.


I would expect the clocks for the 4950x to be 4.9 boost. Add 15% IPC, and it will roll all over Intel/.

I run 4.4Ghz all core on my 3800X 24/7. Was at 4.5Ghz but the voltage increase wasnt really worth the 100Mhz. Still, at 4.4Ghz it matches or beats 9900K @ 5Ghz in CB.

It is--the trend is clear, more people are getting on laptops than desktops.

Also it's a market AMD is really excited about. Traditionally their power/performance made them a non-starter for laptops. Few, if any, vendors wanted to make an AMD laptop since it was going to get worse battery life at a given performance point. Now though, between a smaller node, good core, and their graphics expertise, notebooks are a market they could aggressively target Intel in.

Nice. I like the ability to let the clocks float, which overlooking disables, so I'm not ocing my 3600x. As I said, I get about 4.2 all core, a bit less if I'm doing heavy stuff, and {really short} spikes up to 4.35.

Yeah. One thing I like, too, is the higher base clocks. It's somewhat not, though, for me, as I'm not really in the market for a laptop right now.

For sure, my friend who only games has a 5820k at 4.5GHz and asked whether he should upgrade, I told him to hold off. Long lifespan for those haswell-E chips.
