AMD Ryzen 7 4700G is "Renoir" Desktop AM4 Processor: 8-core/16-thread with "Vega" iGPU

[TheoneandonlyMrK]

Bleh, you seem to be right. The mobile Renoir has 8+4+4 lanes.

Well it does have a GPU attached, and is not made to lay waste to their own released generation R3#£#.
They have a plan it seams.

I can see that being a good plan with 2200G/2400G/3200G/3400G where APUs had 4 cores anyway.
If 4700G will appear in this form, it would be artificially limited to small but definitely measurable degree.

Well it's not an artificial limit, there are no pciex lanes hidden, spare, or fused off, it is a limit designed in.
Artificial implies they did something deliberate post manufacturing to limit it.

It's a design that was made specifically for mobile and adapted to desktop with deliberate choices made on the use of die space, more core's, less PHY's.

This should become AMD's best gaming processor - a monolithic die without all the negatives of the chiplet approach.

This Ryzen 7 4700G probably is faster than Ryzen 7 3700X for the very same reason.

The Vega 512-shader iGPU will render the lowest-end discrete graphics cards obsolete.

You will no longer need any chiplet-based quad-core Ryzen.

Sorry to break it to you, but this is NOT a monolithic design, it does feature 2 CCX each with 4 cores and 4mb of l3 cache.

It's all in one die not a multi chip module so it is monolithic.

 

[btarunr]

8Mo of L3 ? Damn, that's a farcry from the 3700x 36Mo...

36 MB is total cache. L3 is 32 MB. Renoir's total cache is 12 MB.

 

[ShurikN]

I'm quite surprised they made a 8c part for desktop. Genuinely expected an R3 4/8 and an R5 6/12. And nothing more above that. Maybe an Athlon 4000 (4c 4t) for the lower end.

There's a fly in the ointment. Renoir, like its predecessors, spares only 8 PCIe lanes for discrete graphics. It's probably PCI-Express 4.0 x8. So unless you have a GPU with gen 4, you're going to be running something like an RTX 2070S at gen 3.0 x8 bandwidth.

IMO the 4700G will be an i5-10600 killer (non-gaming desktop), if priced at something like $230. The non-gaming market that only needs CPU muscle and couldn't be bothered with even the most basic graphics cards, is rather huge.

I also predict AMD's 10th gen Core i3 competitor will be a Renoir-based 6-core/12-thread processor with 11 MB total cache, and that UHD630-slaying iGPU.

(take on 6c/12t CML-S Core i5 with 8c/16t Renoir, and taken on 4c/8t CML-S Core i3 with 6c/12t Renoir, at comparable price-points)

I predict the moarkoaring could continue with Vermeer, with Ryzen 5 being 8c/16t, Ryzen 7 12c/24t, and Ryzen 9 16c/32t.

Probably should have put some of that in the OP bro

The iGPU performance doesn't really matter, it's simply that having an iGPU option on desktop has been the only missing part of AMD's strategy until now.

I'm sure the motherboard manufacturers are quivering in anticipation of once again being able to clog up motherboard IO panels with useless display outputs like VGA, so they don't have to put a decent amount of USB on them. Yes Biostar, i'm looking at you, kindly FECK OFF with 2000-era display connectors.

Honestly that's not a massive issue, considering that our very own lord and master W1zzard has demonstrated that 8 lanes are good enough: https://www.techpowerup.com/review/nvidia-geforce-rtx-2080-ti-pci-express-scaling/7.html - I doubt that picture will change much with the next gen of GPUs.

With all the reports of RX 5500 showing signs of underperforming with gen 3.0 x8 vs gen 4.0 x8, I don’t doubt things are changing.

Yeah but that seems very specific to that particular GPU. In fact I'd go as far as stating that the 5500 is a mistake that AMD won't make again (until they do).

 

[nikoya]

interested by this CPU/APU to drive a 4k TV for the 2D and light 3D couch games from Steam.
my only concern is that no later upgrades possible as it will be the last gen with this socket.
B550 will last only 1 generation if I am not mistaken ?

 

[Daven]

I could definitely see next gen AMD CPUs and GPUs mimicing the strategy of current Nvidia GPU product splits (16xx and 20xx):

CPU
$50-$250
2-8 core APU
Integrated graphics
Monolithic
Zen 2/Vega

$300-$750
10-20 core CPU
Chiplet
Zen 3

GPU
$150-300
Navi 1 refresh
1408-2560 cores
DirectX 12

$350-$1000
Navi 2
2560-5120 cores
DirectX 12 Ultimate
Ray-tracing
DLSS

Or more possibly:

RDNA2 will be the big core GPUs named 6900(XT) and 6800(XT) and refreshed RDNA1 will get the names 6700(XT), 6600(XT), 6500(XT).

This is probably all the GPU I would need for what I do these days. To me, that’s what this is all about, being able to make a simple, slim, form factor box that would still be very powerful on the CPU front. AMD needed something better than quad-core + IGP SKUs.

 

[AnarchoPrimitiv]

I'll probably have to wait another year or two, but I cannot wait for the real powerhouse APUs, with a CU count approaching that of the PS5 APU/SoC AND (most importantly) with at least 4GB of embedded HBM2e acting as VRAM (but also as a huge L4 Cache for CPU tasks if it's available). The reason why the PS5/Xbox Series X have such great graphical performance while being an APU is the CU count, but also the attached GDDR6 which removes all the shortcomings when an APU has to depend on DDR4 system memory. So you could imagine what 4GB-8GB of HBM2e would be able to do if it was directly embedded in the APU MCM.

I wouldn't care if the socket would have to be the size of Threadripper, I think it'd be amazing to be able to buy APUs as powerful as the next gen consoles. AMD could also help overtake the entire low-end and part of the midrange dGPU market with such APUs. Personally, I think it'd be awesome to be able to skip the dGPU market entirely and the powerful SFF systems that would be possible with powerful APUs would be legendary...

People might start thinking this is something else other than a Zen2 chip with traditional Vega iGPU in it.
Philosophically, im not too sure about having an 8 core one, but can see reasons for a sucess of a 6 core one

I can think of at least one reason to have the iGPU in addition to a dGPU, and that's Adobe who just extended quicksync to AMD CPUs. It was always a feature that worked well with Intel iGPUs and cut a significant time off of rendering, so I could see a professional that works almost exclusively with Premiere picking one of these APUs up as a cheaper way of improving rendering performance than having to buy a more expensive dGPU

PCIe 3.0 at x8 is not a problem for this type of graphics units. I am running my discrete at PCIe 3.0 at x8 and it's perfectly fine.

Renoir probably runs its iGPU at full x16 speed.

It should be capable of Dual graphics, though, on select motherboards.

IIRC iGPU on APU connected using Infinity Fabric not PCIe

Si this is the replacement of ryzen 5 3400g? If so what will the price be?

GPU-Z reports PCIe 16 3.0.

I dont think GPU-Z able to read the internal IF bus. You can see most IGPU from intel are reported either PCI or N/A in GPU-Z

Infinity fabric is a protocol that uses pciex as an interface.

You'd be surprised then to know many offices still have rather decent monitors (for standard office use, of course) using VGA...

 

[ARF]

I would be so helpful for the users if @W1zzard includes these real bandwidth values in GPU-Z:

PCIe 3.0 x16 is 15.75 GB/s
PCIe 3.0 x8 is 7.88 GB/s
PCIe 4.0 x16 is 31.51 GB/s
PCIe 4.0 x8 is 15.75 GB/s
PCIe 1.0 x8 is 2 GB/s

PCI Express - Wikipedia

Also....
With future DDR5 and increased memory modules' capacities, we might be able to run Windows on DDR5 RAM disks.
So that NVMe M.2 SSDs with PCIe 4.0 and 5.0 might be just for added backup capacities and not for Windows.

Si this is the replacement of ryzen 5 3400g? If so what will the price be?

Probably a tier or two tiers above since the Ryzen 5 3400G is just a quad-core.
So, Ryzen 7 4700G should be somewhere around Ryzen 7 3700X with regards to performance, and somewhere around its value + the value of the graphics part in price.
There should be also Ryzen 5 4000G with 6 cores...
