Info 64MB V-Cache on 5XXX Zen3 Average +15% in Games

[Kedas]

Well we know now how they will bridge the long wait to Zen4 on AM5 Q4 2022.
Production start for V-cache is end this year so too early for Zen4 so this is certainly coming to AM4.
+15% Lisa said is "like an entire architectural generation"

That has to be a rather odd custom configuration. Only way I see an Epyc chip reach 36 cores is with 6 chiplets with 6 active cores each. Wonder what about that makes it more suitable to 95W TDP than other possible configurations.

it will be mem bandwidth to min clock to core count ratio. thus 6 channel , 36 core and X clock.

Ah, good catch. Didn't even see the part that it's limited to 6 channels (power consumption of IMC is significant, as non-Pro Threadripper compared to Epyc/Threadripper Pro show). 29 PCIe lanes as well. So the whole platform is castrated, and around a quarter of the IOD can be and likely is deactivated as well.

I keep saying that the IOD uses a significant amount of power and that their use on mobile parts(low power devices) would be very limited and thats why AMD when to the trouble of making a single Monolithic CPU instead for low power devices

It's the way the IOD is connected to the cores that lead to the increased power. What exactly is in the IOD that does not exist in a monolithic die? Answering that will show why. CPU responsiveness is a clue.

Amd could care less about Rocket lake sales going up when compared to Desktop Ryzen, Their priority is the Client market and they just had a few big wins recently, they can charge premium per CCD as compared to desktop where people made a fuss about a $50 increase for for the 5000 line

I think AMD is keeping all it target market's somewhat supplied, while ramping up wafer purchases from TSMC, not letting the foot from the gas pedal, even while pressing that gas pedal only slightly.

This, to prepare the market for greater supply when it comes.

But in this case (Desktop Zen 3D Ryzen), AMD needlessly released that gas pedal in desktop segment, which does not need a huge supply (in the DIY segment) but has disproportional influence...

Meta AMD North Dome 36 Core 95W TDP CPU

Facebook Meta AMD EPYC North Dome CPU and Platform Details

Details on the big AMD EPYC win at Facebook-Meta were shown with the 36C 95W TDP EPYC in the North Dome OCP platform

www.servethehome.com

I was looking at that earlier. That's an odd configuration. If it was 32 cores, AMD could supply it with 4 chiplets, but to supply 36, AMD would need an odd number of chiplets (5?) or give Facebook full 8 chiplets...

Maybe it was a sly move by Facebook to get a CPU with full 256MB of L3 while paying for only 4.5 chiplets... Either way, AMD got its foot in the door, and (what must be embarrassing for Intel), it is one for one replacement of taking out Intel mobo and putting in AMD mobo...

Good point on that. And looking at the configuration, it seems that 6 channels was all that could fit widthwise into the enclosure...

Obviously not a good news for anyone waiting for Zen3D. Maybe I should look into mining RTM since I have i7-5775C.

You almost have to wonder when they start mining on Raspberry Pis...

That new Jetson board from Nvidia looks like it would be a mining beast. I can't wait to see wat happens to that.

I will get a few to just to mine Raptoreum

Please take mining stuff elsewhere (Hopefully, to Mars).

Intel Rocket Lake CPUs sales are being lifted, selling ahead of Zen CPUs in the last week.

Did Rocket Lake suddenly became materially better, more competitive vs. Zen?

No, Rocket Lake sales are up vs. AMD CPUs because AMD did not have Zen 3D in comparisons against Alder Lake.

Maybe it does not make sense to you. Maybe you should think a little harder, until it clicks.

Why would people buy an older Intel CPU that's inferior to the competing AMD CPU just because Intel released a new CPU that's better than Zen 3 in some workloads?

It makes no sense unless prices have been cut by retailers on the older Intel inventory in order to clear it out before the rest of the Alder Lake lineup releases and they have a more difficult time moving Rocket Lake parts. The only other explanation is that the DIY buyers are complete idiots that don't know the difference between an 11 and a 12 when picking parts.

I'd really need to see where you're getting this information because I'm skeptical of the claims you're making. Either they're overblown, due to other factors than you attribute them to, or even just within the normal market fluctuations that can be observed on a month to month basis for no particular reason.

Consider this data from Mindfactory. Although they're a single retailer in a specific market, they do provide data to illustrate the point. Over the span in the graph Intel gained 15% market share, but when you examine the figures closely Intel wasn't selling significantly more CPUs. Rather AMD just isn't selling as many because they don't have the full Zen 3 lineup released and it seems as though more wafers are being devoted to the laptop and server markets and AMD's gross margin is up as a result.

Curious here. Anyone has an idea of the memory size needed for storing say, 90% of most used X86 instructions converted to uops?

I don't know offhand, but Pareto would suggest that ~20% of the instructions in the ISA will account for ~80% of the usage.

Nobody knows. Maybe we'll learn more at CES. Maybe.

Any bets on 170W refreshes for certain Ryzen SKUs?😀

Also, random thoughts on SKU repositioning while taking (legal 🤣) oxycodone:

• 5950xt - 5950x + vcache + clocks - $800-$999
• 5950x -> $650-$700
• 5900xt - 5900x + vcache + clocks - $600-$650 (😍)
• 5900x - $450-$500
• 5800xt (vcache + clocks) $400-$430
• 5800x $330
• 5700x (lower bin version of 5800x) $300
• 5600xt (+clocks!) $280
• 5600x - $250

This is a guesstimate.

So while AMD did not release Zen 3D, and instead released a video, Intel at first threw extra 100 Watts to regain performance leadership.

Next, Intel is throwing in extra 100 pins, to try to keep the performance leadership next year.

That would kill a lot of desire to get Alder Lake if you've got no upgrade path.

Depending on how Zen 4 and AM5 shape up I'm not even sure if more pins will help Intel. They managed to claw back a victory over AMD, but it was only a partial victory and required really pushing the power draw to eek out a few more percentage points at that.

Some of that uplift is as much attributable to the move to DDR5 memory as it is to core improvements on Intel's part and AMD will get that bump soon as well.

Twitter responses are saying the socket already supports Raptor Lake and that ADL just doesn't use all the socket pins so existing motherboard should support RPL, we'll see.

These sockets are somehow supposed to be compatible, but I don't see how.

It's unlikely that you can place 1800 pin into 1700 socket (or the equivalent), only the other way around, but what would be the point of new CPUs being incompatible with old motherboards, but instead, old CPUs compatible with new mobos?

Seems like a strange upgrade, keeping old CPU and upgrading mobo. Mobo is the last thing I want to replace.

 

[Mopetar]

I was hoping that was the case. It would be really shortsighted if Intel didn't use that kind of approach.

 

[Joe NYC]

But is the motherboard wiring all the extra pins even though ADL is not using them?

Or are all of these just power and ground pins?
