Looks like AMD is full speed ahead with Xilinx (technology).
They have dies ready in the lab for testing.
Not sure which Zen core this could be, maybe a first test version of Zen5.
I would assume that the Xilinx engine is a separate die. (probably stacked)
Could also be a Zen4 as substitute...
15% was in games for V-cache equivalent as an entire generation.
The new generation is here now (tomorrow)
So what do you think for games Zen4 compared to Zen3?
I think 20%-25% average, so a little faster over Zen3 V-cache
(about a half year from now we will also have zen4 V-cache but that's...
It would only be the sales that move 2 weeks.
Making sure nobody calls it a paper launch, I don't know...
Maybe then intel's CPU isn't newer, the latest CPU.
Maybe don't give intel 2 weeks to set up an 'unfair' compare power-point to make Ryzen look bad, hurting the sales.
If intel doesn't have...
The PSB feature doesn't vendor lock it, it's the way they use it that vendor locks it. The problem is you need to do an extra effort to not vendor lock it and still be using it, but obviously they don't see the advantage in that for themself.
The condition is that the CPU must recognise the...
Since AMD CPU TDP doesn't mean as much as we would want it to mean:
Checking new motherboards of AM5, Vcore power stage seems to be 80A, 90A or 105A.
When we look at the AM4 motherboards it's more like 50A, 60A or 70A. (although 40A also exist)
high range: 105A / 70A = +50% average current
low...
They are thinking: this is all based on assumptions.... lets wait until all official benchmarks are in, then we can do a proper correction for all of them. ;)
FYI they changed the words on the website
recent launch -> recent announcement (August 4)
https://explore.amd.com/mte/aug-2022-component/register
Not sure if this is an announcement that still has to come before Friday or if they refer to old announcements.
Maybe they just wrote it down wrong...
If true, Userbenchmark will really need to update their test software again for some reason. ;)
Anyway the game score is what will mainly matter, imagine that AMD doesn't even have to release the +64MB version to beat or match the 13900K....
Then the intel CEO better gets used to cold showers...
recent means not long ago, (on august 4)
But I also think it's more likely it's mid September.
What this webinar is about exactly isn't really relevant, the time reference to a launch is the point
You missed key sentence on that page:
So launch before August 4 ????? they really going to have to hurry up.
or someone wrote down the wrong date.
https://explore.amd.com/mte/aug-2022-component/register
edit: could be the 'launch' event to say that they will be available in September.
Looking at the 'leaked' benchmark results (if true). The ratio between non AVX-512 and AVX-512 on single thread look very similar to intel.
I assume the main target was to remove this server advantage for intel and it looks like they got their target.
Even if the 'leaks' aren't true, the...
If zen5 doesn't come a year after zen4 they could fill the gap with zen4 on 4nm since they would already have done most of the work assuming zen4 mobile is not zen4c on 4nm.
Also on the slide:
"ISA extensions for AI and AVX-512"
So AI and AVX512 are two different things? or just a strange sentence.
For Zen5:
"Integrated AI and Machine Learning optimizations"
Some AI library that works with the integrated GPU as accelerator?
But you would use your bigger GPU to do...
Moore's Law Is Dead said 7-9% IPC
That's not bad, if it would be only a shrink it would be 0% IPC
N5P gives probably +20% clock (vs 7nm), add some extra power budget to 125W and you get your +40% multi thread 16 core over Zen3.
And Vcache version still has to come on top of that.
Do you really...
He also talked about TDP, that there wasn't a profile 'fused' yet (since they haven't tried/decided that yet) somewhere between 105 and 170 but certainly not maxed out.
I think they were shooting for an 125W TDP setting similar like the 12900k
In that case they get 45% more speed for the same...
About the blender demo AMD was like pressing gas and break at the same time by the marketing people.
1) They compared intel CPU and wisely said both are 16 cores. not mentioning the threads, (AMD has a Bulldozer trauma about 'counting as full cores')
It's a fair comparison from CPU point of...
Noctua already stated a long time ago that with the exception of 2 low profile coolers you can use your AM4 cooler on AM5.
https://noctua.at/en/which-noctua-cpu-coolers-are-compatible-with-amd-am5
About losing space with dual chip: adding extra chips in between lanes to cover the distance isn't...
Keep in mind that volume production of V-cache dies is a subset of the current volume production line, it's not a parallel extra production line it's extra work on a limited number of the volume production dies.
This means that AMD decides how many will be made or not.
And first batches were at...
There will be almost a year between the provided gaming performance numbers (still the same) they gave and the launch date.
I think we all feel like this is released later than what they internally planned.
And they first had almost certain more versions in mind than 8 core only.
(based on...
We may not be able to overclock the V-cache version.
Would this be a heat issue or some timing issues that AMD fears.
Seems a bit strange, if it's heat wouldn't we detect it that the overclock makes it too hot. Maybe it can break easily (mechanically) when getting hot.
DDR5 prices are going in the right direction so it may not be a big issue releasing AM5 in Q3.
Although intel has a good low thread load score with 'low prices'.... like 12700k.
Not sure if multi-thread 8 Core Zen4 will beat the 12700K for only $400 (probably less by then.)
Maybe they launch...
The 15% is the average of 5 games shown in AMD's slide.
We all know the advantage will be very load dependant, even in games we see a small change for League of Legends but a big +25% for Monster Hunter World both DX11.
For the relevant changes on the Desktop software spectrum we will have to...
It does indeed seem to be an XMP version for AMD as some already guessed correctly.
"Ryzen Accelerated Memory Profile"
AMD RAMP Is XMP For AMD's Ryzen 7000 CPUs, Accelerates DDR5 Memory on AM5 Platform (wccftech.com)
I was just checking when this thread started it's 7 months ago that they annouced it with the +15% in games, not much has changed since then.
I would think since he emphasis "it's hard" in the interview that they had some unexpected issues that pushed it back, they didn't gave a date so it could...
In this interview they say they are checking out the market for V-cache
it's still possible other SKU's are coming later.
Higher price a bit lower clock....not sure how people will react.
Very unlikely since we expect an IPC >+25% and possible all core clocks of 5Ghz. But it's possible that same target market isn't going to upgrade again so soon after an upgrade to 5950X3D (half year later)
You can also see a spring release as a good thing that they wait until they have enough so it wouldn't be a paper launch.
Nobody expected a January launch right?
BTW for everyone who wanted the '3DNow' label good news the edit will be easy :)
The die size doesn't look very big for 16 cores (unless Zen4 is much bigger than Zen3), they removed a lot of L3 and L2 cache and replaced it with cores that are power limited. (not sure about L2 I hope it's more than 1MB)
And the cost of stacking L3 cache is probably a lot cheaper than you...
If tomorrow AMD doesn't mention any future product on 6nm with stacking then you can take it as official since there isn't any important TSMC customer using 6nm stacking. (While there are already a few official sackings on 5nm)
(Marketing people never mention what it can't do only what it can.)...
About 6nm or in between full nodes supporting stacking or not:
I see that the press release of N4P does mention an 6% density increase but no mention of 3Dfabric.
Then 7 weeks later the press release of N4X, it does mention 3DFabric but no mention of a density increase.
If there is no density...
Yes but the thing is that it is also shrinking and for stacking size is important hence extra work that needs to be done again so they may have decided to skip that part. (certainly since the amount of stacking request is limited for now)
