Zen 2 APUs/"Renoir" discussion thread

Ehm, this is better than ADL-N in what way exactly? I get this is probably the Raven2 replacement intended to target ATOMs but come on AMD, you were supposed to destroy them not join them!

With all the budget stuff AMD has released over the years I can't say I'm surprised.

This is just the latest version of Brazos.

 

[mikk]

Imagine unironically thinking that gaming performance matters for this portion of the market.

You know what matters here? That a system is responsive for day to day tasks, and has excellent battery life. Having slightly less rubbish (but still rubbish) graphics capabilities is frankly meaningless.

The same people criticized Intel for their minimalistic iGPUs and hailed AMD not that long, now it's fine. AMDs lowcost platform Dali launched early 2020 with a Vega 3 on a 14nm node. Almost 3 years later we get 2CU RDNA2 on a 6nm node. Great progress.

Oh please, nobody being realistic thought Raven Ridge was a competitive platform for ultrabooks. It had FAR too many shortcomings compared to Intel offerings at the time.

Re: Dali, okay? And? Has the needs of people looking for a basic laptop suddenly changes such that they need 2-3x the compute throughput in the last couple of years?

The problem with this thing is that it may fall short of ADL-N in ALL AREAS, incluiding IGP if it really just have 128kb cache.

That said, we dont the specs for sure yet.

 

[dark zero]

WIth 3 CU at least Mendocino would give a massive advantage with the GPU department since Alder Lake -N looks decent in CPU department.

Sure, ADL-N will be impressive, though I wouldn't be surprised if Mendocino maintains a lead on battery life. Outside of that though, yeah.

AMD Ryzen 3 7320U processor spotted, it's most likely the new Mendocino Zen2/RDNA2 APU - VideoCardz.com

One of the first Ryzen 7000 CPUs at large Over at Userbenchmark website one can find a new entry featuring yet unreleased AMD Ryzen 3 7320U processor. This Ryzen 7000 CPU is most likely not based on Zen4 microarchitecture, in fact, it may not even be Zen3. The Ryzen 3 7320U is reportedly based...

Looks like the specs of one SKU of Medochino may have leaked - the Ryzen 3 7320U. Has a 2.4 Ghz base. Userbenchmark though so could be fake.

If that should turn out true that's one hell of a stupid model naming and numbering again. Now I'm afraid this is going to be the sub 6 cores chip on AM5. Please not. *knocks on wood*

The detected memory chips are LPDDR5 so they are laptop based I guess, but I have seen some GFX 1037 with DDR4, so they are heading to laptops and AM4 I think.
GFX1036 is Raphael, DDR5+LPDDR5
GFX1037 is Mendocino, DDR4 + LPDDR5

Seems both are APUs, SMU version 13.0.5 and 13.0.8. One of them is behaving like YC.
They have new VCN version also, 3.1.2

One funny bit is that one of them is LPDDR5+DDR5 and the other is LPDDR5+DDR4 !

 

[jpiniero]

Well it's going to be branded Ryzen 3 because of what they are going to charge for it. And you're not going to brand it 6xxx or 5xxx because it's new.

It's possible. I think the alternative might be busted IGP Rembrandt/Phoenix, however many chips they get where that happens.

AM4 would be a better fit at least.

If it's Mendocino it's a crippled (half the FPU, half the channels) Zen 2 core using the brand and numbering of the upcoming Zen 4 gen. That's a new level of misleading compared to Lucienne. At least call it Athlon and/or use a more Athlon-like 7xx numbering.

Edit: I forgot that the leaked slide included the mention "Scalable mainstream NB, Athlon to Ryzen 5"

We already had mentions of Ryzen 3 7420U and Athlon Gold 7220U. Ryzen 5 to go. 🤦

 

[NostaSeronx]

.... I have seen some GFX 1037 with DDR4, so they are heading to laptops and AM4 I think.
...

AM4 would be a better fit at least.

DDR4 variant would most likely be inserted into FT5 rather than AM4.

FT5 => 64-bit DDR4
FT6 => 64-bit LPDDR5

AM4 has only supported 128-bit DDR4 products.

Only in concept with the E300SFF AM4-Stoney and concept AM4-Banded/Raven2 with 64-bit DDR4/LPDDR4. Did AM4 ever hint at 64-bit/Single-channel support.

FT5 support allows Mendocino to replace Pollock and utilize the same RAM as Jasper Lake. Specifically, single-channel variants of N5100/N5105/N5095 in EDU/Chromebook.

Issues with Pollock:
- Under-utilized by EDU/Chromebook instead opted for Jasper Lake
- Intel went 2933 MHz, AMD went backwards to 1600 MHz. Downscaled 2400 MT/s became rare, while Downscaled 3200 MT/s didn't.
- AMD's product became expensive and rare.

Mendocino on FT5 can be a plug in fix, while leeching off high-volume Jasper Lake. That is basically spec'd the same in the same use market.

But it's not the Zen 4 Gen, it's the 7000 series. Again, if they want to charge Ryzen 3 prices they are going to call it Ryzen 3.

 

[SteinFG]

AM4 has only supported 128-bit DDR4 products.

And why can't mendocino have a 128bit bus? All we know is that FT6 is 64-bit.

 

[NostaSeronx]

The R3000-series is indicated with a 64-bit PHY
Whereas R1000-series is indicated with a 128-bit PHY.

LPDDR5 FT6 is replacing FP5 dual-channel. (2x64-bit @ 2.4 GT/s to 1x64-bit @ 6.4 GT/s)
DDR4 MDN FT5 is improving upon PLK FT5 single-channel. (1x64-bit @ 1.6 GT/s to 1x64-bit @ 3.2 GT/s)

There isn't a case for 128-bit DDR4 on A0h-AFh models.

The market for these chips are in the embedded side. DT-FT4 Stoney was viable, so would DT-FT6/DT-FT5 MDN, etc.

What? I'm hearing about 64-bit R3000 for the first time, where does it come from? Also, It's A0 because of it's order in CPUID, there's already cpu with 90 index - van gogh.

 

[Thibsie]

I dont see the problem, at all.
Much less annoying than Lucienne/Cézanne

 

[dark zero]

Makes me think... it will be better than the Ryzen 5300U?
I mean CPU wise it should be, but how about GPU wise?

AM4 would be a better fit at least.

At least Lucienne is double channel.
Heck, I see an offer of a Ryzen 3 5300U Lenovo laptop with the cost of 257 dollars... if Mendocino is that bad... I better go to Lucienne and then use a external dGPU in case I need more GPU power.

There is no way that a 2CU RDNA2 with literally no cache and 64 bits would beat a 6CU Vega, if the Vega has dual channel.

So, is recommended to go to the Ryzen 3 5300U in case I can obtain it?
If that so, thanks for the information. I'll go with the laptop with that processor.

PS: And despite I have a laptop with a Ryzen 7 and a GTX1650, but if somehow I need to send to the maintenance to said laptop, I need a backup and I saw it for 280 bucks (sadly in Peru is very hard to obtain decent deals for less than 300 dollars) and looking for 2nd hand market is extremely hard since is mostly overpriced.

AMD introduces Ryzen/Athlon 7020 "Mendocino" APUs with 6nm Zen2 and RDNA2 architectures - VideoCardz.com

AMD Mendocino is almost here Today, AMD is introducing its new low-power CPU series designed for budget laptops. AMD Mendocino is part of the 7020 series (according to AMD’s new product naming schema), which means Zen2 CPU architecture and 7th generation of Ryzen. Unlike Intel, who dropped...

videocardz.com

Videocardz says the launch of Medochino is today. They also have the SKU list - a 7520U, a 7320U and an Athlon Gold 7220U with the cores cut to two.

 

[naad]

4 cores with halved cache and an anemic rdna2 GPU at around 100mm2, can't but help feel another 40mm2 would make this quite a little beast.. in this case most of the die area is spent on analog circuitry like memctl and i/o

 

[Abwx]

That s a 8-15W SKU, at 4C/8T that s a quite good product for everyday basic usage and it should be more efficient than RMB.

even zen1 Dali dual cores felt pretty competent in light laptop use. These will feel blazing fast by comparison

Can't say I have any complaints about the 3.5GHz 2C/4T Zen1+ cores in my HTPC. Zen2 should obviously be even better. Couple with an NVMe drive, and you have a decent combo for a budget laptop.
