Testing the Ryzen 9 4900HS Integrated Graphics

Under the hood of the Ryzen 9 4900HS, aside from the eight Zen 2 cores, is an enhanced Vega 8 graphics solution. For this generation of mobile processors, AMD is keeping the top number of compute units to 8, whereas in the previous generation it went up to Vega 11. Just by the name, one would assume that AMD has lowered the performance of the integrated graphics. This is not the case.

For the new Ryzen Mobile 4000 processors, the Vega graphics here are enhanced in three main ways over the previous generation. First is that it is built on the 7nm process node, and AMD put a lot of effort into physical design, allowing for a more optimized version that has a wider voltage/frequency window compared to the previous generation. Secondly, and somewhat connected, is the frequency: the new processors top out at 1750 MHz, rather than 1400 MHz, which would naturally give a simple 25 % boost with all other things being equal. Third on the list is memory, as the new platform supports up to DDR4-3200, rather than DDR4-2400, providing an immediate bandwidth boost which is what integrated graphics loves. There’s also the nature of the CPU cores themselves, having larger L3 caches, which often improves integrated graphics workloads that interact a lot with the CPU.

Normally, with the ASUS Zephryus G14, the switching between the integrated graphics and the discrete graphics should be automatic. There is a setting in the NVIDIA Control Panel to let the system auto-switch between integrated and discrete, and we would expect the system to be on the IGP when off the wall power, but on the discrete card when gaming (note, we had issues in our battery life test where the discrete card was on, but ASUS couldn’t reproduce the issue). In order to force the integrated graphics for our testing, because the NVIDIA Control Panel didn’t seem to catch all of our tests to force them onto the integrated graphics, we went into the device manager and actually disabled the NVIDIA graphics.

This left us with AMD’s best integrated graphics in its Ryzen Mobile 4000 series: 1750 MHz of enhanced Vega 8 running at DDR4-3200.

Our comparison point here is actually a fairly tricky one to set up. Unfortunately we do not have a Ryzen 7 3750H from the previous generation for comparison, but we do have an Honor Magicbook 14, which has a Ryzen 5 3500U.

This is a 15 W processor, running at 1200 MHz and DDR4-2400, which again makes the comparison a little tricky, but it is better than comparing it to the Intel HD630 graphics in the Razer Blade.

We also re-ran the benchmarks on the latest drivers with AMD's 65 Desktop APUs, the Ryzen 5 3400G (with Vega11) and the Ryzen 3 3200G (with Vega 8). These are running at DDR4-2933, the AMD maximum officially supported by these APUs (which means anything above this is overclocking).

This is a pretty substantial difference, no joke.

Hopefully we will get more variants of the Ryzen integrated graphics to test, along with an Ice Lake system.

    Der8auer did a comparison against the 9980HK and the 4900HS still came on top in performance. It even manages to keep up with the 5 GHz, 90 watt core i9 inside the Helios 700, which is a beast of a laptop in terms of size and weight. Reply

    goddamn intel fanboys truly want to distort shit so there is no real competition left in this space. Reply

    There is no real consumer "competition" in this space. Intel's 10nm production is fubar'd for the time being, To the point where expected products are just now trickling into the market place. AMD could capitalize on this, but their production is constrained because they don't have full control of their own production. This is the mobile market, not the desktop CPU market where you can have retail sales. OEMs are key here.

    2020 will be a bad year for laptop options.

    Yes, you are right.
    It is crazy because the 6-core Razer laptop is also slightly more expensive than 8-core Asus laptop.

    In all fairness, Razer is usually more expensive than Asus. Reply

    hmm ok so the Intel CPU was supposed to be at 45w but could not maintain that probably du e to thermals, its supposed to clock higher but ditto and the 2060 is a higher performance version, however other tests still show the Ryzen ahead on 8 core Intels as well, it also seems to be a common result that the AMD is a long long way ahead on its battery life, not sure about other countries but this week in the UK we have had every online seller doing ads on TV pushing Intel laptops to the max, no doubt paid for by Intels rebate scheme dirty tricks me thinks but the truth will out gen 10 indeed lol Reply

    95% of the market vs 5% of the market - that's called playing to the largest potential audience. Sorry but Intel outsells AMD at every single price point - regardless of what the AMD fanboys say - Revenues do not lie. Reply

    well other sites say different about who out sells who, others here have even posted links that show this.
    "Revenues do not lie. " of course they dont, specially when you overcharge for your products

    "Revenues do not lie. " of course they dont, specially when you overcharge for your products"

    The market says otherwise, they think the products are well priced, and Intel sells all they can make - so just because YOU can't afford them doesn't mean they are over priced - and if they were sooo overpriced, seems like AMD would be in MUCH better financial situation than they are.

    again prove it, look at the 3 links i posted farther up. yea..right well priced, over priced is more like it, Epyc Rome, more cores, it some cases HALF the price, and better performance. Reply
