AMD "Renoir" Die Shot Pictured

Here is the first die visualization of AMD's new "Renoir" processor. Having made its debut with Ryzen 4000 series mobile processors, "Renoir" succeeds a decade-long legacy of AMD APUs that combine CPUs with powerful iGPUs. AMD designed "Renoir" on TSMC's 7 nm silicon fabrication process. The die measures 156 mm², and has a transistor-count of 9.8 billion. The die shot reveals distinct areas that look like the processor's 8 CPU cores, a cluster of GPU compute units, the integrated memory controllers, southbridge, and PHYs for the chip's various I/O.

"Renoir" features 8 CPU cores based on the "Zen 2" microarchitecture, divided into two 4-core CCXs (CPU complexes). Unlike on 8-core chiplets meant for "Matisse" or "Rome" MCMs, the "Renoir" CCX only features 4 MB of shared L3 cache, probably because latencies to the memory controller are low enough. The L2 cache per core is unchanged at 512 KB. The "total cache" (L2 + L3 on silicon) adds up to 12 MB. The iGPU of "Renoir" is a hybrid between "Vega" and "Navi." The SIMD components are carried over from "Vega," while the display- and multimedia engines are from "Navi." The iGPU features 8 NGCUs that add up to 512 stream processors. Infinity Fabric covers much of the die area, connecting the various components on the die. AMD introduced a new dual-channel integrated memory controller that supports LPDDR4x at up to 4233 MHz, and standard DDR4 up to 3200 MHz.

Any word on when the NDA ends and we'll see some reviews?

Except this is quite obviously not a die-shot (as in: colorized macro photography), but a visualization.
Frankly, it looks like a remastered SimFarm map.

I am wondering if memory phy is more like 64-bit GDDR6 by looks of it. Look at navi 10 die shot (exactly the same amd way different to Piccasso )

the cpu cores are like rdna cu and not cpu cores, it's a render and not a die shot :'(

Those are RDNA WGPs; Two CUs per WGP. So, that is a 16 CU render. It's probably not Renoir, but Van Gogh or Cezanne.
No L1 Graphics, but L2 is per WGP, rather than shared. Of the L2, it looks like 2 MB L2.
The bottom thing across the memory phys, looks like a Navi 10/14 command processor.

NGCUs are basically;
Core+L2 SRAM - 0.5MB L3 SRAM - L3 Interface - 0.5 MB L3 SRAM - Infinity Fabric stuff - Another L3 Interface
Also, the thing that is next to it is awkwardly replicated. It kind looks like southbridge I/O.

It definitely is Renoir.

Sad part... OEM's still can't "de-couple" from Intel, and will continue to configure and market such AMD offerings to gimp their performance and not promote the merits of such technology.

AMD's Project Fusion has been created with the idea to use the iGPU shaders for software acceleration:

"Support OpenCL C++ directions and Microsoft's C++ AMP language extension. This eases programming of both CPU and GPU working together to process support parallel workloads."
en.wikipedia.org/wiki/AMD_Accelerated_Processing_Unit#Heterogeneous_System_Architecture

Today some apps use Intel's Quick Sync only.

How is it possible I don't know.

Is that so?

It is so.



For clarification, the AMD Ryzen 7 4800HS is not a CPU, but an APU with 7 graphics cores.

But what is gimped with that notebook? AMD only offers mobile APUs, which is what this news post is about.
You throw something out there, don't back it up and then change the subject matter. :kookoo:

The purpose of an APU? Asus don't even know what an APU is and what it can do. They don't even mention that it has graphics units inside.

Not to mention that they most probably use single-channel memory out of the box.

So you're making assumptions based on partial specs of an unreleased product... Lovely, just lovely...

It seems like it's single channel, but there's a spare SO-DIMM slot. Supposedly it has 16GB of RAM soldered down.

This thing switches to its discrete external RTX 2060 only in 3D gaming mode.
In all other instances, it uses its Vega iGPU for hardware acceleration.

I mean this:

What Does Heterogeneous Computing Really Promise?
TH: Do you have a sense of the optimization ratio, CPU versus GPU?
KS:
I think we’re seeing, on our AMD system here, CPU usage drop by about 10% and then the GPU utilization increases about 20%.

TH: So increasing GPU usage by 20% saves 10% off your CPU utilization?
KS:
I’d say 15% to 20%, yes, but I’d probably need to look up the exact number.

And this is a bad thing how? I mean, correct me if I'm wrong but I would think having the discrete GPU handle the gaming load and the iGPU handle everything else (everyday tasks, watching video/movies, etc.) would be a GOOD thing. Would you rather the iGPU handle the heavier gaming workload and the RTX 260 handle the everyday stuff? :wtf:

The SIMD components are carried over from "Vega,"
And like that, you lost me.

There is sense to it though. Vega is focused more on computing performance so having it as the onboard iGPU over anything Navi.

The last hurrah I guess.
We're near D3D13 territory, mesh shaders and ray tracing being the stars, and Vega is not part of it.

D3D13? I thought Microsoft is content with extending D3D12 by adding more feature levels

Exactly. I don't see how this is a bad thing. NVIDIA's Optimus implementation is really good.

And seeing how the current NVIDIA Studio Driver and current Radeon Pro drivers are working well (not in Optimus, of course) in my desktop, I'm sure this configuration would work out just fine.
180W power adaptor
Support Type-C PD 3.0 up to 65W
Err.. why not 100W (20V/5A)? PD 3.0 supports this.

But this thing would definitely replace my Dell G5 5587 provided that it is at most $1,399.00.

Next change is not just features, and some are even being dropped, like tessellation.
