AMD Zen iGPU to have performance similar to an RX 460

[Djole123]

So, as you know, Zen APUs will bring some great performance improvements, but what about the integrated Radeon RX GPU?

 

Well, some rumors say that the iGPU in the Zen APUs (possibly only in A10 lineup) will have performance that is just a tad bit lower than the RX 460. 

 

That would mean that if you want to do light gaming, you won't be needing to pay a 100$ extra when you can just plug in to the iGPU!

 

That combined with power efficent CPU would also mean less power consumption which is great.

 

But it will use system memory so that may be a bottleneck.

Looks like AMD might become a strong competitor in the gaming laptops market with iGPU and GPU CF.

It all depends on the price. If they make Zen+RX APU at a reasonable price it would smoke Intel when it comes to budget computers.

what does that slide has to do with iGPUs?

[Cracklingice]

I really hope this is the case.  Crossfire and AMD dual graphics seem to scale fairly well so I could see getting rather good performance out of a gaming quality Zen and an RX480 running dual graphics mode.  I just hope that they actually enable the functionality instead of relying on DX12 multi gpu only as I don't foresee myself doing dx12 gaming for a couple years.

IDK. It was chosen completely randomly just so I could make the post look a little bit bigger.

Dual graphics has always ran with only the lowest end cards and with cards of similar performance to the igpu in the apu. The a10 7850k could only run dual graphics with an r7 250. For this reason I think zen will only run dual graphics with a rx 460. It most probably won't run dual graphics with a 480.

R9 380 performance (ish) + decent CPU = Hello sub $300 budget builds.

Possible - but on laptops that would be sick

I don't think price is much of a problem, this is AMD we're talking about here. It's the power consumption we should be worried about.

460 is confirmed at 60W and the APU should be 90W

Hella sick. I'm personally pretty excited for this. An integrated desktop gpu which is able to pull of 1080p medium settings and a decent cpu for around 150$ is quite a good deal. Not to mention all the possibilities of mini itx builds.

Actually it's both. The engineering sample of Zen CPUs had a 65-95W TDP, but I expect a tad bit more with that beefy iGPU. But not as much as when you plug in an actual 460.

[Energycore]

If anyone of you thinks RX 460 is going to perform like an R9 380, prepare to be dissapointed. It's got less than 40% the SPs of an RX 480 so I just can't see it perform like the 380 which is 60% 480

[awesomeness10120]

Cool. GTX 950 performance in a much smaller package.

It *should* be more than that, follow the trend of 480 = 970~ and 470 = <970 and >960

Well it's not a full fledged RX 460. It's going to be bottlenecked because it uses system memory rather then it's own memory, also it won't be exactly 460 performance, it'll be a bit lower. So it is essentially GTX 950 performance.

[Belgarathian]

If that's true... Then APUs might be making a comeback with a vengeance.

I suppose it could be locked to the 460, but in the past it had a range of GPUs that would work didn't it?

 

They should bring back cartridge CPUs.  Make the APU like 5 to 6 inches long by 3 to 4 inches tall with full RX480 die but uses system ram.

You do realise its the same performance, not the same gpu.

But that's gonna dissipate a TON of heat. It would be sub 9590 TDP, so it would need a water cooler. And they cost, so it's not suitable for budget builds.

Well maybe not cartridge because it would probably not handle a large cooler well, but still make the chips BIG with lots of power!   BTW, large air coolers can dissipate large amounts of power.  It should be possible to cool even 450 watts TDP on air.  Although I don't know how a CPU die would deal when the GPU die is putting out 80°C right next to it.  Maybe this could never happen.  

 

Although - keep in mind that GPU coolers are terribly inefficient.  Even the aftermarket solutions like windforce are stuck in the constraints of a certain number of PCIE slots.  A CPU sized cooler like the Noctua ND-15 is capable of much better heat dissipation.

[themaniac]

welp we can say good bye to intel competing in the igpu front if this is true

[samcool55]

Damn if it handles games well like LoL, Dota 2 and CS:GO this one might be their golden ticket to get into the asian market.

Not really. The a10 5800k could run either the hd 6570 or 6670 (both being basically the same card just with different clock speeds). The a10 7850k could only run dual graphics with the r7 250 and nothing else.
