AMD Radeon RDNA2 680M iGPU Beats NVIDIA MX450 Discrete GPU

[Uskompuf]

The recently announced AMD Ryzen 6000 series mobile Zen 3+ processors feature a significant graphics improvement with up to 12 RDNA2 Compute Units available. These new graphics solutions have recently been tested and compared by an engineer working for Lenovo in China. The Radeon 680M and Radeon 660M feature 12 and 6 RDNA2 Compute Units respectively and have been tested against the NVIDIA MX450 and the Intel Iris Xe Graphics G7. The Radeon 680M represents an 85% performance improvement over the Radeon RX Vega 8 and is 24% faster than the discrete NVIDIA MX450 mobile GPU in 3DMark. This lead narrows in real-world tests where the 680M is only 1.1% faster than the MX450 and the 660M is 37% slower.

The mid-range Radeon 660M is still significantly faster than the Intel Iris Xe Graphics G7 (96EU) found in the i7-12700H beating it by 9% in 1080P gaming. The review also looks at power efficiency for the Radeon 660M & 680M showing that in their highest power configurations performance increases by 10% for the 660M and 42% for the 680M. The Radeon 680M remains behind the NVIDIA GTX 1650 Max-Q which holds a 25% lead. The Ryzen 6000 mobile series will be available in laptops starting from next month.

That the problem with western review. They test nothing. When Chinese reviewer made benchmark of everything

I can't wait to see the the desktop APUs when they're released as well as the mini-PCs that'd be possible with both the desktop APUs and mobile APUs

 

[wurschti]

I'm excited to see what the 6800U can do. Normally you can get an ultrabook with that CPU and it can game at 1080p.

I wouldn't hold my breath desktop APUs being too powerful because Ryzen 1000 to 5000 has shown that people don't even want iGPU these days.

Though personally I want AMD a create separate product line for CPUs with powerful iGPU, unrestricted by power and thermal constraints like mobile ones. Basically $200 budget graphics card replacement. Dreaming that for years. Even one SKU would be fine in my books. Just think about it. Tech sites will list a CPU as best budget GPU. Fucken hilarious.

Same here. Instead of AMD adding iGPU with 2! RDNA2 cores to each Zen4 CPU i would rather they focus on delivering the best CPU and then special G (APU) models that have at least 12-24 RDNA2 cores like Rembrandt on laptop but even stronger. But with fewer CPU cores. Like 6 max to fit the package.

also dgpuless 6800h with lpddr5 cause 4800 mts vs 6400 should benefit it quite a lot.
memory latency isn't good on lpddr but bandwidth is better so should give some good uplift, tdp down to 35 w "tdp" so 45 boost would be my dream laptop

AMD/Intel APU are not powerful enough to replace decent lower end GPU just because both aren't interested into making one that could.

AMD could make a 256bit LPDDR5 chip with 24+ compute units that would be better than most low end GPU and could even compete at the mid range ala Apple M1 Pro/MAX. it wouldn't be supported on AM4/5 but on laptop, that do not really matter.

But i suspect that neither of them want that, they prefer to sell dedicated GPU on the side and keep iGPU as low end.

The 6800h is in GTX1050 territory. That's impressive.

High-end integrated graphics like these rarely sell well (and because they require the same number of dedicated memory channels as a discrete GPU, then you might as well go with discrete.

Integrated only works because there is zero additional system cost to use it (128-bit bus max); as for why Zen 4 is including it, I'd say it's because they finally have the space (and what else are you going to use all that DDR5 memory bandwidth for? Alder Lake is wasting that bandwidth on the same 32 eus as Rocket Lake!)

Well not sure how high end integrated graphics rarely sell well since there was almost none except few outlier like that intel CPU with a vega chip. Apple Pro/Max sell very well.

The things is Apple have no interest into making a dGPU. So it make sense for them to build huge APU with a heavy iGPU. it do not compete with their own product.

Since most of the time they re-use the same die as desktop for mobile GPU, they would have to spend more to develop a new chip and it would compete for other product for fab capacity. It's the main reason. AMD prefer to re-use as much as possible their own chip and it do not make sense for them to make a new one just for that specific case.

As for bandwidth, getting into mid range GPU market, the chip would need more bandwidth than 128 bit DDR could offer.

They won't sell well, because he demand is not there!

By the time you spends all that money on memory bandwidth, you cold have simply included the discrete card!

Thanks to ARM superiority, Apple now lives in it's own world; but that doesn't mean they suddeny licked the big iGPU scaling problem:

M1 Max With 32-Core GPU Is Slower Than 100W Laptop RTX 3080, Barely Beats Low-Wattage RTX 3060 in Gaming Benchmarks

A few gaming benchmarks show that Apple’s M1 Max is unable to compete with a 100W laptop RTX 3080, and barely beats an RTX 3060

I wouldn’t write off Apple producing a dGPU. We still don’t have any real news about their in-house Mac Pros to complete the transition to Apple silicon, which would have to outperform the 2x dual Vegas they offer now to maintain that market. There’s also the afterburner card they designed which I’d assume is upgraded as well.

It's pretty difficult to really say there is no demand because there is no offer. I bet if they could make one, the demand would be there. I would have bought those kind of laptop instead one with a dGPU but there was no offer except those cheap iGPU. (and when i bought it, Vega 8 was the top !).

As for adding a discrete GPU, it would still cost less to add another 128 bit bus on top of the actual one than add another chip + other coldplate/heat pipes + another set for VRM + another memory bus.

So it would still be cheaper. And since you wouldn't have to mess up with the dGPU <-> iGPU switching or routing, it would be a simpler and more stable product.


As for ARM superiority, this is not a thing. It's more a mix of Apple design superiority with a closed source OS that they manage and better process (5nm).

Rembrandt 6800H iGPU was shown to be 2x faster at 1080 than Intel's 1280P iGPU in real games. Where did this 9% rubbish come from?

Go pander your BS rhetoric elsewhere

It is the 660M doing the 9% uplift, and the 680M in the 6800H has twice amount of CUs

Have to wait for supply to get to us, cant just steal something off the line.
